Chickpea (Cicer arietinum L.) is a relatively new crop in Saskatchewan and acreage has undergone a rapid expansion during the past decade. However, uncertainty remains regarding growth and yield responses of this grain legume to N and P fertilization under the semiarid environment of Saskatchewan. Field experiments were conducted at various locations in Saskatchewan to investigate chick pea response to starter N (0, 15, 30, and 45 kg N ha-1) and P (0, 20 and 40 kg P2O5 ha-1) using desi cv. Myles and kabuli cv. Sanford. Starter N was side banded (2.5 cm to the side and 4 cm below the seed) and the P was placed in the seed row or side banded. Starter N promoted early vegetative growth of both desi and kabuli chickpea, but kabuli seed yield was unaffected by N application. Application of 30 or 45 kg N ha-1 enhanced desi yield by as much as 221 kg ha-1. Starter N reduced N2 fixation by kabuli chickpea whereas N2 fixation by desi apparently was not as sensitive to inorganic N. Phosphorus (40 kg P2O5 ha-1) enhanced chickpea vegetative growth, although only desi seed yield was significantly enhanced (121 kg ha-1). Shoot N and P accumulation in both chickpea types generally increased with P application, but N2 fixation was unaffected. The results suggest that although N and P application had no effect on kabuli seed yield, desi yields may be optimized by the application of low rates of starter N (i.e., 30 kg N ha-1) and P (20 kg P2O5 ha-1).

Field experiments at four sites over 3 yr evaluated the effect of banded and broadcast application of fertilizer P, with and without application of Zn on dry matter yield at flowering, and seed yield of flax. Application of P fertilizer increased dry matter yield and seed yield on a number of soils even when crop growth and yield were restricted by extremely dry conditions. Banded P was more effective than broadcast or residual P in increasing flax yields. Increases in yield due to Zn application were infrequent and showed no definite relation to soil Zn or P. Increases in yields with Zn application generally occurred only where P had been broadcast that season or the year before, while decreases in yields with Zn occurred more frequently where P had been banded. The results showed that increases in flax yields in response to Zn application are most likely to occur where P fertilizer is broadcast at relatively high levels or on soils with a history of heavy P application.

Field experiments were conducted at Pulses and Oilseeds Research Station, Berhampore, Murshidabad, West Bengal during <italic>pre kharif, kharif and rabi</italic> seasons of 2011-12, 2012-13 and 2013-14 to study the effect of water soluble fertilizer spray on growth and yield of greengram, blackgram, lathyrus, lentil and chickpea. Pulses are mostly grown by the farmers without any fertilizer application, as positive effect of supplying legume plants with supplementary nitrogen was found to have beneficial effect on enhancing growth and increasing seed yield. Five sets of experiments were laid out in a split plot design with three replications <italic>viz.</italic> two levels of basal fertilizer application (F<sub>0</sub> -No basal dose of fertilizer, F<sub>1</sub> -Basal dose of fertilizer application @ 20, 40, 40 kg N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O ha<sup>−1</sup>.) as factor A in main plot and seven levels of foliar spray of water soluble fertilizers at pre flowering stage (no spray, 0.5% NPK(19-19-19), 1% NPK(19-19-19), 2% NPK(19-19-19), 3% NPK(19-19-19), 2% DAP, 2% Urea) as factor B in sub plot. Significantly higher seed yield of pulses were recorded with application of 2% urea spray over basal dose of fertilizer application The lowest seed yield was recorded with no basal fertilizer and spray. Without basal dose of fertilizer application, 3% NPK (19-19-19) spray recorded highest seed yield. Under basal dose of fertilizer application, the results showed a gradual increase in yield with the increase in concentration of NPK (19-19-19) fertilizer spray up to 2%, Among the fertilizer spray treatments irrespective of basal dose of fertilizer application, urea spray was significantly better than all other treatments.

Yield Responses

In a field experiment, fertilizer source (poultry litter vs. commercial), plastic mulch, row cover, and fertilizer rate (residual from 1990 study vs. additional) were applied in factorial combinations to determine the effect on vegetative growth and production of triploid watermelons. Litter (3.12 % total N) was re-applied at the rate of 13.2 Mt·ha-1 along with commercial fertilizer (6N-10.5P-20K) at 1.1 Mt·ha-1. Plastic mulch showed the greatest influence on vegetative growth and production variables by increasing vine length 26.1 cm, leaf area 61.8 cm2, yield 4207 kg·ha-1, melon number 741 ·ha-1, and average melon weight 0.8 kg, over unmulched plots. Plastic mulch with or without row cover increased melon number significantly when compared to plots without mulch or row covers. Poultry litter increased vine length, yield, and average melon weight 15.4 cm, 1971 kg·ha-1, and 0.5 kg, respectively, when compared to commercial fertilizer. Poultry litter in combination with row cover increased yield by 3864 kg ·ha-1 over commercial fertilizer with row cover, and approximately 2567 kg·ha-1 over poultry litter and commercial fertilizer without row cover. Additional fertilizer increased average melon weight 1.3 kg.

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.

Yield Responses

The effects of nitrogen (N) and potassium (K) on stem growth and yield responses of Australian waxflowers were investigated. Experiments were conducted in commercial plantings at 3 sites in South Australia. Plantings of Chamelaucium uncinatum cvv. Alba (2 sites) and Purple Pride (1 site) and a Chamelaucium hybrid (C. floriferum x C. uncinatum), known locally as Walpole wax (1 site), were 3-5 years old when the study began in 1990. Nitrogen and K were applied at rates up to 160 g N and 80 g K/plant.year. Application of N significantly (P<0.05) increased stem growth, with the magnitude varying considerably between sites and years. Increasing the rate of applied N from 0 to 80 or 160 g/plant.year increased mean tip-growth of flowering stems of cv. Alba by 47.7% at site 1 and 137.1% at site 3, and of Walpole wax by 144.2% at site 2. In contrast, the effect on cv. Purple Pride was minimal. Tip-growth also varied significantly (P<0.05) between sites. Applied K did not significantly affect stem growth at any site. Application of N significantly (P<0.05) increased the yield of 41-70 and >70 cm stems, and total stem yield at all sites with variation between years and cultivars. For example at site 2 increasing the applied N rate from 0 to 80 or 160 g/plant .year increased total stem yield by 13.9, 176.2 and 77.6% in 1991, 1992 and 1993, respectively. In contrast, the effect of applying K was inconsistent. Application of N significantly increased the weight of prunings at all sites and yield of prunings also varied between years. Applied K significantly affected the yield of prunings at site 3, where application of 80 compared with 0 g1plant.year decreased the yield by 17.9%. For all sites, the mean ratios between total stem weight and total biomass harvested were in the range 0.68-0.82. The effect of applied N was only significant at site 3, where the ratio decreased from 0.76 to 0.57 when the rate of applied N increased from 0 to 160 g/plant.year. The effect of K was not significant at any site. At sites 1 and 2, and for cv. Alba at site 3, application of 80 or 160 g N1plant.year decreased mean stem dry matter by 8.0, 9.3 and 11.0%, respectively. Stem dry matter content also varied significantly between years at all sites. The effect of applied K was only significant at site 3, where application of 80 g1plant.year reduced dry matter content by 5.3% compared with 34.2% for the nil rate. Based on data for all sites, stem fractionation showed that dry matter yields (as a percentage of total stem dry weight), were in the order, woody tissue (3 15-49.9%) > leaves (22.1-29.2%) > flowers (15.9-25.8%) > tip-growth (5.0-21.9%). The effect of applied K on the yield of the different stem parts was only significant (P<0.05) at site 1, where in 1991 yield of the tip-growth fraction decreased. We conclude that to develop effective N fertiliser strategies for waxflowers requires knowledge of (i) soil type, in particular residual N fertility; (ii) annual vegetative growth cycle (i.e. periods of growth flushing); (iii) harvest period; and (iv) flowering time. For cultivars or hybrids harvested when vegetative growth is negligible (e.g. winter) N nutrition can be optimised, while for those harvested during periods of vegetative flushing (e.g. September-November) lower rates of N should be applied to ensure tip-growth is not excessive. Although yield responses to applied K were inconsistent, we recommend 20 g K/plant.year to ensure that productivity is maintained over the 5-10 years flowering stems can be harvested from commercial plantings.

Yield Responses

The effect of 2 rates of piggery waste on the growth, nutrient uptake and yield of barley (cv. Galleon) were compared with a fertiliser mixture of superphosphate and urea in the field. The piggery waste was either applied as a slurry (16 kL/ha or 32 kL/ha) or as a solid (0.5 t/ha or 1.5 t/ha). Both the fertiliser mix and the slurry significantly increased the growth and yield of barley while the dried manure failed to improve growth and yield. The effects of treatments on the nutrient concentration in plant tissue throughout the year were small and mainly not significant, while the increases in nitrogen and phosphorus content in the crop reflected the changes in dry matter production. The grain yield responses to fertiliser and to the slurry appeared due to an increase in nitrogen available to the crop rather than to the increase in the supply of phosphorus or other nutrients. The higher rate of the slurry reduced the boron concentration and increased the sodium concentration in the tissue but the concentrations of these elements were not great enough to affect plant growth adversely. However, the increase in sodium concentration following application of the slurry suggests that there may be some risk in the build up of sodium in the soil with the continued use of high rates of slurry, particularly in drier environments. The experiment indicates that the slurry was as effective as fertiliser in eliciting a response and was more effective, in the short term, than the dried form of manure.

Yield Responses

The effect of detillering on the growth and yield of a six-row barley (cv. Beecher) and a two-row barley (cv. Schooner) grown under adequate and restricted watering was studied in a glasshouse experiment. The vegetative growth of both varieties responded in a like manner to detillering and reduced watering, but there were significant differences in the grain yield responses. Detillering reduced the grain yield per plant in both the non-stressed and stressed treatments of Schooner and the non-stressed treatment of Beecher, but had no significant effect on the yield of Beecher when watering was restricted. The experiment indicated that there may be genetic differences in response to detillering under some conditions and suggests that some caution needs to be exercised when using detillering experiments to predict the value of genetic uniculms.

Field experiments were conducted during rabi (winter) seasons of 2010-11 and 2011-12 at the Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur to study the effects of nitrogen and phosphorus on growth, dry matter production and yield of French bean. A randomized complete block design was followed with 10 combinations of N (0,50, 100, 150 and 200) and P (0,22, 33, 44 and 55) kg ha-1 along with a blanket dose of control. All the treatments showed the maximum leaf area index (LAI) at 65 days after sowing (DAS). All the treatments showed the maximum total dry matter production, crop growth rate and net assimilation rate at harvest and at 55-65 DAS, respectively in both the years. LAI, dry matter production, CGR, NAR and seed yield significantly increased with the increase in nitrogen and phosphorus level upto 150 kg N and 44 P kg ha-1 , respectively. Similar trend was followed in maximum number of pods (9.45) and seed yield (1563.33 kg ha-1). The treatment comprises with 150 kg N and 44 P Kg ha-1 gave the highest seed yield which was 51.40 and 54.30 % higher than control plots.Bangladesh J. Agril. Res. 41(4): 759-772, December 2016

Inconsistent Result

Light and boron play a significant role in the physiological growth and yield of crops such as groundnut. Even so, there has been little information on the application of boron in groundnut, while no information is available in Bangladesh regarding the imposition of light in groundnut. Therefore, two field experiments were conducted in order to evaluate the physiological growth and seed yield of groundnut. Treatments included two levels of light, viz., L0 = normal day length (≈12-h light) and L = normal day length + 6-h extended light at night (≈18-h light); three levels of boron, viz., 0-kg B ha-1 (B0), 1-kg B ha-1 (B1) and 2-kg B ha-1 (B2), and two groundnut varieties, viz., V1 = ‘Dhaka-1’ and V2 = ‘BARI Chinabadam-8’. The results obtained from the experiment revealed that the highest LAI, LAR, LMR and RWR were recorded in L, B2 and V2 variants, while NAR was the highest in L0 and B0. Moreover, it was noted an inconsistent result for RGR found for boron application. Based on the results, it could be concluded that boron is one of the factors responsible for higher yield of groundnut; nevertheless, under the extended light, it is not possible to get the highest yield.
