Many studies have been conducted on the effects of annual legumes on subsequent corn production but they rarely extended beyond a second succeeding crop. We have therefore conducted field experiments on a sandy gravelly loam at St-Anselme and on a silty loam at Deschambault in eastern Quebec to determine the residual effects of (i) faba bean (Vicia faba L.) and soybean (Glycine max [L.] Merr.) on a third succeeding corn (Zea mays L.) crop and (ii) 2 consecutive years of these legumes on a second subsequent corn crop. In monoculture or following legumes, corn was fertilized with 0, 50, 100 or 150 kg N ha−1 as NH4NO3. The corn stover and whole-plant dry matter yields (DMY), and the ear and whole-plant N uptake were higher following faba bean grown 3 years earlier than in monoculture at both locations. At Deschambault, the stover DMY of second subsequent corn following 2 consecutive years of faba bean did not vary with the N application. At both locations, the DMY, N concentrations and N uptake of second subsequent corn were higher after 2 consecutive years of faba bean than after other previous crop sequences. Two consecutive years of soybean had significant effects on the DMY and N uptake of a second subsequent corn crop with N application at Deschambault. At both locations, the N-fertilizer replacement values (NFRV) of soybean were lower or equal to 0 kg N ha−1. The NFRV (DMY and N uptake bases) of faba bean grown three years earlier and of 2 consecutive years of this pulse varied widely between locations.

The costs of N fertilizer and concern for sustainable agriculture have led to renewed interest in the use of legumes as a source of N for succeeding non-legume crops. In this regard, field experiments were conducted in 1987,1988 and 1989 on a Rivière-du-Loup sandy gravelly loam (Ferro-Humic Podzol) at St-Anselme and on a Chaloupe silty loam (Orthic Humic Gleysol) at Deschambault in eastern Quebec, Canada, to determine the effects of 1 or 2 years of faba bean (Vicia faba L.) Outlook and soybean (Glycine max [L.] Merr.) Maple Amber on subsequent forage-corn (Zea mays L.) Pioneer 3979 dry matter yields (DMY) and N uptake, and the N-fertilizer replacement values (NFRV) of the different crop sequences. Corn in monoculture or following a legume was fertilized with 0, 50, 100 or 150 kg N ha−1, and legumes received 20 kg N ha−1 as NH4NO3. In 1989, at both locations, the DMY and N uptake of forage corn in monoculture or following 2 consecutive years of soybean, or subsequent to soybean and faba bean grown 2 years previously, increased linearly with N application. After 2 consecutive years of faba bean, the DMY were not affected by increasing fertilization, but the N uptake generally increased proportionally to N application. The estimated NFRV (on a DMY basis) after 2 consecutive years of faba bean varied from 60 to 125 kg N ha−1 at St-Anselme, and from 100 to 110 kg N ha−1 at Deschambault for the ears and stover, respectively. The NFRV estimated for the same cropping sequence varied from 122 to 129 kg N ha−1 at St-Anselme and from 104 to 131 kg N ha−1 at Deschambault, for the stover and ears, respectively, on the basis of N uptake. For 2 consecutive years of soybean, it averaged 14 kg N ha−1 at St-Anselme and 33 kg N ha−1 at Deschambault, on the basis of the DMY; when based on the N uptake, the NFRV of 2 consecutive years of soybean varied from 14 to 21 kg N ha−1 at St-Anselme and from 0 to 15 kg N ha−1 at Deschambault for the stover and ears, respectively. The average NFRV (based on the DMY) for faba bean grown 2 years previously were 17 kg N ha−1 at St-Anselme but NFRV varied from 0 to 16 kg N ha−1 at Deschambault for stover and ears, respectively; on the basis of N uptake, the NFRV for the same crop sequence averaged 24 kg N ha−1 at St-Anselme, but varied from 0 to 15 kg N ha−1 at Deschambault for the stover and ears, respectively.

Field experiments were conducted in 1987 and 1988 on a Rivière-du-Loup sandy gravelly loam (Ferro-Humic Podzol) at St-Anselme and on a Chaloupe silty loam (Orthic Humic Gleysol) at Deschambault in Eastern Quebec. In monoculture, or following a legume, corn (Zea mays L.) Pioneer 3979 was fertilized with 0, 50, 100 or 150 kg N ha−1, and faba bean (Vicia faba L.) Outlook and soybean (Glycine max [L.] Merr.) Maple Amber received 20 kg N ha−1 as NH4NO3. In 1987, the whole-plant dry-matter yields (DMY) of corn increased linearly with the supply of N at St-Anselme and Deschambault. The stover and whole-plant N uptake, also increased linearly with the N levels at both locations, but the supply of N had no effect on the ear N uptake. In 1988, at St-Anselme and at Deschambault, the ear, stover and whole-plant DMY of plants not receiving N and following faba bean were significantly higher than those in monoculture or following soybean and not fertilized with N; these differences between previous crops were more evident at St-Anselme than at Deschambault. At both locations, the DMY of the stover, ears and whole plants of corn were more responsive to the increased N levels following soybean or corn. At both locations, the N uptake of corn following faba bean did not increase with the N levels in contrast to corn following corn or soybean. The N-fertilizer replacement values (NFRV) for soybean (on the basis of corn DMY) were negligible or lower than 0 kg N ha−1 at both locations. At St-Anselme, the values for faba bean were higher than 150 kg N ha−1, but averaged 32 kg N ha−1 at Deschambault (DMY basis). On the basis of corn N uptake, the NFRV of faba bean ranged from 92 kg N ha−1 for ears and was higher than 150 kg N ha−1 for whole plants at St-Anselme, and varied from 37 kg N ha−1 for stover to 44 kg N ha−1 for ears at Deschambault.Key words: Previous crop, forage corn, soybean, faba bean, N-fertilizer replacement value

Factors Affecting

In pot and field experiments, N application somewhat increased the I content of the harvested crop, although I concentrations in the herbage decreased considerably (diluting effect of increased dry matter yields). Herbage I contents were not consistently affected by chemical fertilizers which produced no yield response. I contents were up to 13 times higher in dicotyledenous pasture species than in grasses. I contents varied between grass species and to less extent between varieties of a single species. Contrary to earlier New Zealand data, good quality grasses were lower in I content than medium-value and inferior grasses. Small I dressings were less effective than larger amounts in terms of percentage return in the harvested crop; residual effects in later cuts were always small. The effectiveness of I dressings depended on soil type and tended to be lowest on soils of low natural I content. ADDITIONAL ABSTRACT: Studies were with ryegrass in pots and pastures. N dressing increased I uptake by the crop but reduced the I content considerably because of the diluting effect of higher DM yields. Dressing with fertilizers which did increase yield did not affect herbage I content consistently. Dicotyledonous species in pasture had I contents up to 13 times that of grasses. The I content of grasses varied over a 2-fold range but variation was smaller in a given species. Good quality grasses had a lower I content than inferior grasses. Smaller I dressings gave a smaller percentage return in the crop than larger amounts; the efficiency depended on soil type and tended to be less for soils with the lowest natural I content.

A trial was conducted on an Ethiopian Vertisol from 1990 to 1995 to determine the residual effects of fertiliser N applied to tef [Eragrostistef (Zucc.) Trotter] on the grain and straw yield, N content, and total N uptake of succeeding crops of durum wheat (Triticum turgidum var. durum) and tef. The mean agronomic efficiency of 60 kg fertiliser N ha−1 was 13.1 kg grain kg−1 fertiliser N applied in the current year and 5.4 kg grain kg−1 fertiliser N applied in the previous year. Thus, the residual fertiliser N benefit was equivalent to 41.2% of the response to current season N application for the two cereal crops. The mean rates of apparent recovery of fertiliser N were 65.8% for current season N application and 31.0% for previous season N application. Soil organic matter and nitrate levels increased linearly in response to both previous and current season N application rates. The current study demonstrates that the residual effect of fertiliser N enhanced the yields and N contents of the grain and straw of both wheat and tef, resulting in a significant increase in total N uptake. Any analysis of the profitability of fertiliser N response should reflect the multi-year benefit period. Key words: N recovery, N residue, N uptake, tef, wheat

Plot Design

An attempt was made to evaluate the N supplied by crop residues through crop rotation experiments on Oxisols and Ultisols. Field experiments were conducted on three typical soils following a split-plot design. Main plots were three rotations: soybeans, corn , corn; fallow, corn, corn; and continuous corn. Subplots included two treatments: 0 and 110 kg/ha of fertilizer N. Fair yields of soybeans were obtained while corn yields were good, especially on the Humatas soil (Ultisol), 6240 kg/ha. Substantially higher yields were obtained in the Bayamón (Oxisol) and Humatas soils from the first corn crop following soybeans or corn than when following fallow. Although the second corn crop yield following soybeans was slightly higher than the first, the second corn crop after initial corn and fallow were substantially higher. The effect of applied N at all sites was striking, regardless of the previous crop. There was no apparent relationship between the amount of N returned to the soil and yields of subsequent corn crops.

As concern over NO3-N pollution of groundwater increases, California lettuce growers are under pressure to improve nitrogen (N) fertilizer efficiency. Crop growth, N uptake, and the value of soil and plant N diagnostic measures were evaluated in 24 iceberg and romaine lettuce (Lactuca sativa L. var. capitata L., and longifolia Lam., respectively) field trials from 2007 to 2010. The reliability of presidedressing soil nitrate testing (PSNT) to identify fields in which N application could be reduced or eliminated was evaluated in 16 non-replicated strip trials and five replicated trials on commercial farms. All commercial field sites had greater than 20 mg·kg−1 residual soil NO3-N at the time of the first in-season N application. In the strip trials, plots in which the cooperating growers’ initial sidedress N application was eliminated or reduced were compared with the growers’ standard N fertilization program. In the replicated trials, the growers’ N regime was compared with treatments in which one or more N fertigation through drip irrigation was eliminated. Additionally, seasonal N rates from 11 to 336 kg·ha−1 were compared in three replicated drip-irrigated research farm trials. Seasonal N application in the strip trials was reduced by an average of 77 kg·ha−1 (73 kg·ha−1 vs. 150 kg·ha−1 for the grower N regime) with no reduction in fresh biomass produced and only a slight reduction in crop N uptake (151 kg·ha−1 vs. 156 kg·ha−1 for the grower N regime). Similarly, an average seasonal N rate reduction of 88 kg·ha−1 (96 kg·ha−1 vs. 184 kg·ha−1) was achieved in the replicated commercial trials with no biomass reduction. Seasonal N rates between 111 and 192 kg·ha−1 maximized fresh biomass in the research farm trials, which were conducted in fields with lower residual soil NO3-N than the commercial trials. Across fields, lettuce N uptake was slow in the first 4 weeks after planting, averaging less than 0.5 kg·ha−1·d−1. N uptake then increased linearly until harvest (≈9 weeks after planting), averaging ≈4 kg·ha−1·d−1 over that period. Whole plant critical N concentration (Nc, the minimum whole plant N concentration required to maximize growth) was estimated by the equation Nc (g·kg−1) = 42 − 2.8 dry mass (DM, Mg·ha−1); on that basis, critical N uptake (crop N uptake required to maintain whole plant N above Nc) in the commercial fields averaged 116 kg·ha−1 compared with the mean uptake of 145 kg·ha−1 with the grower N regime. Soil NO3-N greater than 20 mg·kg−1 was a reliable indicator that N application could be reduced or delayed. Neither leaf N nor midrib NO3-N was correlated with concurrently measured soil NO3-N and therefore of limited value in directing in-season N fertilization.

Abstract. In this study we use the multifractal analysis, through generalized dimensions (Dq) and the relative entropy (E(δ)) to investigate residual effects on wheat and grain, biomass and nitrogen content, of fertigation treatments applied to a previous crop. The wheat crop covered nine subplots from a previous experiment on melon response to fertigation. Each subplot had previously received a different level of applied nitrogen and plants from the previous melon crop had already taken up part of it. Many factors affect these variables, causing it to vary at different scales creating a non uniform distribution. The Dq were used to study the relation between scales meanwhile E(δ), and their increments between scales, were used to identify the scale at which the variable had a maximum structure and compare with the scaling behavior of the nitrogen applied. The E(δ) is particularly appropriate for this because of does not require any prior assumptions to the structure of the data and it is easy to calculate. The four variables studied presented a weak multifractal character presenting a low variation in Dq values, around the unit, that wasn't relevant for the study. On the other hand, the E(δ) and the increments in E(δ) help us to detect changes in the scaling behavior of all the variables studied. To this respect, the results showed that the applied nitrogen through fertirrigation dominated the wheat and grain biomass response as well as nitrogen content of the whole plant; surprisingly grain nitrogen content didn't show the same structure than the applied nitrogen. At the same time, there was a noticeable structure variation in the biomass and nitrogen content at the smaller scales that correspond to the previous cropping root arrangement due to uptake of the applied nitrogen.

Method Of P Application

Yield responses of faba bean (Vicia faba L.) cv. Fiord to applications of fertiliser phosphorus (P), as superphosphate, were measured in 2 field experiments. The P was either (i) placed with the seed while sowing at 6 cm depth and also cultivating at 3–4 cm below the seed (drilled P) or (ii) placed 3–4 cm below the seed while sowing at 6 cm depth (banded P). This was done when the seed and fertiliser were placed in rows at either the standard 19 cm apart (current recommendation) or 38 cm apart (makes it easier to sow into the stubble of the previous crop). Yield of dried shoots and seed (grain) increased with increasing amount of P applied (0–30 kg P/ha in experiment 1, 0–45 kg P/ha in experiment 2), but were unaffected by the method of P application or spacing between seed and fertiliser rows. Therefore, (i) up to 45 kg P/ha can be drilled with the seed while sowing faba bean crops (current farmer practice) and (ii) faba bean can be sown and fertilised at 38-cm spacings making it easier to sow into the stubble of the previous crop than the 19-cm spacing currently being practiced.

The fate of 15N-labelled fertilizer applied to rice (Oryza sativa L) was studied in microplots established within two field experiments comprising a range of stubble levels, stubble management techniques, N application rates and times. The first experiment investigated uptake of soil and fertilizer N in plots where application of 0 or 100 kg N ha-1 to the previous rice crop had produced 11.5 and 16.1 t ha-1 of stubble respectively. The stubble was then treated in one of four ways-burn (no till); burn then cultivated; incorporated in autumn or incorporated at sawing. Microplots within these large plots received 60 kg ha-1 of 5% 15N enriched urea at sowing, just prior to permanent flood (PF), or just after panicle initiation (PI) of the second crop. The second experiment was undertaken within a field in which half of the plots had stubble from the previous three rice crops burned, while the other plots had all stubble incorporated. In the fourth successive rice crop, the two stubble management systems were factorially combined with three N rates (0, 70 or 140 kg N ha-1) and three application times (PF, PI or a 50 : 50 split between PF and PI). Nitrogen uptake and retention in the soil were studied within 15N-labelled microplots established within each of these large plots. Only 4% of the 15N applied at sowing in the first experiment was recovered in the rice crop, while delaying N application to PF or PI increased this to an average of 20% and 44% respectively over the two experiments. The doubling of N application rate doubled fertilizer N uptake and also increased uptake of soil N at maturity by 12 kgN ha-1. Three years of stubble incorporation increased average uptake of fertilizer and soil N in the second experiment by 5 and 12 kg N ha-1 respectively. In both experiments, the soil was the major source of N, contributing 66-96% of total N uptake. On average, in the fourth crop, 20% of fertilizer N was in the grain, 12% in the straw and 3% in the roots, while 23% was located in the top 300 mm of soil. A further 3% was in the soil below 300 mm. The remaining 39% was lost, presumably by denitrification.

This study aims to explore the optimum nitrogen (N) application method by analyzing effects of variable N application stages and ratios on the N absorption and translocation of high-yield summer maize (DH661). The study included field experiments and <sup>15</sup>N isotopic dilutions for pot experiments. Results showed that the yield was not increased in a one-off N application at the jointing stage. The uptake of fertilizer-derived N in the grain increased with the increasing of N applied times. Compared to a single or double application, total N uptake (N<sub>up</sub>) and biomass increased significantly by supplying N at the six-leaf stage (V6), ten-leaf stage (V10) and 10 days after anthesis in ratios of 3:5:2 and 2:4:4. The fertilizer-derived recovery rates were 67.5% and 78.1%, respectively. The uptake and utilization of fertilizer-derived N was enhanced by increasing the recovery rate of N supplied after anthesis, and reducing the absorption of soil-derived N. Therefore, the 2:4:4 application ratios was the optimal N application method. &nbsp;
