Experiments were conducted to investigate the effects of applications of N, P, K, B and dolomitic limestone on yields of strawberry (Fragaria × ananassa Duch ’Redcoat’). Yields were increased by applied N and P, but were not affected by added potassium or boron. Second crop yields were increased by a greater extent than first crop yields by both N and P. First crop yields were increased by a pre-planting application of dolomitic limestone on a sandy loam soil with initial pH of 4.9. Leaf tissue concentrations at full bloom of 1.4–3.2% N, 0.17 to 0.34% P, 0.7 to 1.6% K, and 26–57 ppm B appear to be in the sufficiency range for the cultivar Redcoat. The concentrations of these elements in strawberry leaf tissue were lower after harvest than at full bloom.Key words: Strawberry fertility, leaf tissue concentration

The effects of preplant soil applications of B, Mo and dolomitic limestone on yields and leaf tissue nutrient concentrations of Rally peas were investigated at five locations with initial soil pH levels of 5.1–5.9. Experiments were conducted for two consecutive growing seasons at each location. All treatments were preplant incorporated in a 2 × 2 × 2 factorial design with five replicates. Yields of shelled peas, adjusted to tenderometer 100, varied between experiments from 1.1 to 4.8 × 103 kg ha−1 and were not generally affected by B, Mo or lime at application rates of 2.0, 0.25 and 10 000 kg ha−1, respectively. Also, the micronutrient and lime treatments had no significant effects on germination, vine length, pea/vine ratio or maturity. Leaf tissue B, Mo and Mg concentrations were increased by the applications of B, Mo and dolomitic limestone, respectively. However, leaf tissue Ca concentration was not affected by the lime treatment. The results indicate that leaf tissue concentrations of 16–74 μg g−1 B, 0.04–1.34 μg g−1 Mo and 0.23–0.55% Mg were within the sufficiency range.Key words: Peas, boron, molybdenum, dolomitic limestone, yield, leaf tissue concentration

Water Treatments

Abstract Various insecticides applied as transplant water treatments were compared with foliar and soil treatments for TA and TFB control and for their effects on the yield of flue-cured to bacco. Tests were conducted on a Chesterfield-Mayodan-Bourne sandy loam soil at the Southern Piedmont Agricultural Agric. Res. and Ext. Cntr., Black-stone, VA. Eleven treatments and an untreated check were established in a RCB design with 4 replications. Plots, 4 X 40 ft (1 row X 24 plants), were separated by single untreated guard rows. The Temik treatment was applied in a 14-inch band using a tractor mounted-Gandy granular applicator and immediately covered with 6 inches of soil at bed formation on 21 May (soil temperature 75 °F ambient temperature, 88 °F, soil pH, 5.6; weather, sunny; soil moisture, good). The Admire drench treatment was applied to tobacco seedlings in 288-cell float trays 24 hrs before transplanting. The treatment was applied with a CO2-pressurized backpack sprayer that delivered 1 fl oz of Admire 240 FS in 1.84 gal of water/1,000 plants through 8003LP tips at 20 psi. Treatments were watered in with an additional 1 gal of water immediately after application. ‘Coker 371 Gold’ flue-cured tobacco was transplanted and the transplant water (TPW) treatments were applied in 204 gal solution/acre with a Holland plunger-type transplanter on 21 May. The weather was sunny, and soil and ambient temperature was 75 °F and 88-91 °F, respectively. Foliar applications of Orthene were applied on 3 Jul and 8 Aug with a CO2-pressurized backpack sprayer that delivered 28 gpa at 60 psi through TX-12 nozzles (3 per row. The weather was clear, wind speed was less than 5 mph, and ambient temperature was 84-86°F at each application. Except for insect control, tobacco production followed Virginia Cooperative Extension recommendations. Dipel 4 L (Bacillus thuringiensis) was applied for tobacco hornworm control on 3 Jul. TA were counted on the upper 4 leaves of 10 plants/plot about once a week from 6 to 10 wks after transplanting. On 22 Aug, TA damage was rated for each plot on a scale of 0 to 10: 0 = no signs of aphid feeding; 10 = all leaves showing severe damage resulting from TA infestations including honeydew, sooty mold, necrotic leaf tissue, and exuviae. TFB feeding holes were counted on 5 plants/plot on 2 and 26 Jun, 2 and 5 wks after transplanting. Tobacco was harvested and cured and yield was determined. Data was analyzed by ANOVA and significantly different means were separated by Waller-Duncan K-ratio t-test (K = 100). TA count data were transformed to log10 (x + 1) before analysis.

Urea Ammonium Nitrate

Soils of northwest New Mexico have an elevated pH and CaCO3content that reduces Fe solubility, causes chlorosis, and reduces crop yields. Could biosolids and fly ash, enriched with Fe, provide safe alternatives to expensive Fe EDDHA (sodium ferric ethylenediamine di-(o-hydroxyphenyl-acetate)) fertilizers applied toPopulushybrid plots? Hybrid OP-367 was cultivated on a Doak sandy loam soil amended with composted biosolids or fly ash at three agricultural rates. Fly ash and Fe EDDHA treatments received urea ammonium nitrate (UAN), biosolids, enriched with N, did not. Both amendments improved soil and plant Fe. Heavy metals were below EPA regulations, but high B levels were noted in leaves of trees treated at the highest fly ash rate. pH increased in fly ash soil while salinity increased in biosolids-treated soil. Chlorosis rankings improved in poplars amended with both byproducts, although composted biosolids offered the most potential at improving Fe/tree growth cheaply without the need for synthetic inputs.

Different Growth Stages

SummaryThe leaching behaviour of a highly saline-sodic, moderately permeable, sandy-loam soil was evaluated under continuous and intermittent submergence conditions in a longterm field study in the presence of rice and subsequent wheat and sesbania crops. Leaching curves with respect to both desalinization and desodification showed that leaching efficiency was considerably higher with intermittent than with continuous submergence. The curves were useful in determining the amount of leaching water needed for a given mode of water application to reduce harmful levels of salinity and sodicity to acceptable ones. Empirical equations were determined to fit the experimental data. Their comparison with another empirical equation from published bare-field data of this site showed that leaching efficiency under crops was higher than under fallow. From the desodification leaching curve, it is concluded that in reclamation of these soils there is no need of the application of any amendment like gypsum. The soil salinity and sodicity data recorded at different growth stages and crop yields showed that leaching during the rice growing season, under intermittent submergence without previous leaching, decreased salinity and sodicity throughout the top 100 cm of the soil to levels safe for the successful cultivation of rice and subsequently the relatively deep-rooted crops of wheat and sesbania.

The Impact

The optimum temperature regime for Solanum tuberosum cv. Russet Burbank is usually 20/15°C day/night. We studied the impact of heat stress (30/25°C, day/night) on the growth of this heat sensitive cultivar under controlled conditions (UW-Biotron). Plants were grown in sandy-loam soil which tested at 1500 Kg/ha Ca. Plants were at the maximum temperature for 6h during the middle of the day with a photoperiod of 14 hrs. All pots received identical amounts of total N (rate: 225 Kg N ha1.). The treatments were: (1) NSN: non-split N (N application 1/2 emergence, 1/2 two wks later): (2) SPN: split-N (1/2 emergence 1/6 at 2, 5 and 8 wks later); (3) SPN+Ca: Split-N+Ca (Ca at 2, 5 and 8 wks after emergence, total Ca from CaNO3 was 113 Kg ha1). Total leaf FWT and DWT was significantly reduced in NS treatment by heat stress at 13 wks as compared to optimum conditions. However, this was not reduced in SPN and SPN+Ca. Under heat stress: (a) SPN + Ca gave the highest leaf FWT and DWT, stomatal conductance, transpiration rate, and leaflet tissue Ca content; (b) Young expanding leaflets gave higher growth rate with SPN and SPN + Ca than NSN; (c) Ca content of mature leaflet decreased progressively in both NSN and SPN but not in SPN + Ca. Our results show that application of Ca and N during heat stress can mitigate stress effects and that maintenance of a certain level of calcium in leaf tissue is important under heat stress.

Collard Green

Microbial tea from a commercial source and a homemade manure tea were evaluated for 2 years under organic and conventional fertility regimens. Testing with different fertility regimens allowed broader assessment of tea efficacy. Collard green (Brassica oleracea L. var. acephala cv. Top Bunch) yield and soil microbial activity were measured after microbial tea applications were made in three fertility treatments (conventional, organic, or no fertilizer amendment) on a previously unfertilized sandy loam soil. Spinach (Spinacia oleracea L. cv. Hellcat) and collard green yields were determined after commercial microbial tea application to a silt loam soil previously managed with organic or conventional vegetable crops in open fields and under high tunnels. Results indicated that nutrient additions influenced crop yields, even doubling yield. This demonstrated that improved nutrient availability would affect yield at the chosen locations. However, microbial tea applications did not affect crop yield. These results did not support the hypothesis that microbial tea improves plant nutrient uptake. Additionally, soil microbial respiration and biomass were unaffected after two or three tea applications.

Petiole Sap

Tomato (Lycopersicon esculentum Mill.) was grown with drip irrigation on an Arredondo fine sand and on an Orangeburg fine sandy loam to evaluate the effect of N and K time of application on petiole sap, leaf-N and -K concentrations, fruit yield, and to determine N and K sufficiency ranges in leaf tissue. On the sandy soil, N—K at 196-112 kg·ha-1 were applied 0%, 40%, or 100% preplant with the remainder applied in 6 or 12 equal or in variable applications in 12 weeks. With the variable application rate, most nutrients were applied between weeks 5 and 10 after transplanting. On the sandy loam soil that tested high in K, only N (196 kg·ha-1) was applied as above. Petiole sap K concentration declined during the season, but was not greatly affected by treatment. Petiole NO3-N concentrations decreased during the season from 1100 to 200 mg·L-1, and the decrease was greater with preplant N treatments. On the sandy soil, marketable fruit yields were lowest with 100% preplant, intermediate with 100% drip applied (no preplant N), and highest with 40% preplant and 60% drip applied. With 100% drip applied, yields were higher with 12 even applications than with either six even weekly applications or with 12 variable N and K applications. With 40% preplant, timing of application had little effect on yield. On the sandy loam soil in 1993, yields were highest with 100% preplant, intermediate with 40% preplant and 60% drip applied, and lowest with all N drip applied. In 1994 when excessive rains occurred, yields were similar with all preplant and with split N applications. Petiole N concentration was correlated with tomato yield, especially at 10 weeks after transplanting. The best correlation between sap-N and total yields occurred between 4 and 6 weeks at Gainesville and between 4 and 10 weeks at Quincy.

The use of compost as an organic source of nutrients and soil improvement may help to increase the sustainability of intensively managed vegetables. Bell pepper (Capsicum annuum L.) transplants were planted into silver-colored polyethylene mulched beds in a sandy loam soil amended with 0 or 22.4 Mg·ha–1 dairy manure compost. Preplant P was added to all beds at 78 kg·ha–1. During the season, N (as NH4NO3) was added about every 10 days. Total N rates for the season were: 0, 32, 65, or 96 kg·ha–1. Percent of N in pepper leaf tissue increased from a low of 2.7% without N to3.8% at the high N rate. Leaf P concentrations were higher in 0 N plots than in other rates. Compost resulted in higher leaf concentrations of Ca. There was an interaction of compost and N rates for percent of culls. Compost increased percentage of culls with 0 or 32 kg·ha–1 N, but decreased or did not affect cull percentage at 65, or 96 kg·ha–1 N. Compost did not affect other yield parameters measured. Marketable yields increased from 11 Mg·ha–1 with 0 N to 18 Mg·ha–1 with high N, although the regression was not significant, due to extreme variability within the field.

Leguminous Crops

Background: Presently, labour force is diminishing and becoming costlier. In agriculture management of weeds in cropped field has become a real challenge to the farmers, since weeds are affecting the crop yields due to competition for growth resources. Intercropping of leguminous crops and application of pre-emergence herbicides offers an ample scope for weed control. Methods: The present study was conducted at University of Agricultural Sciences, Bengaluru during 2016 and 2017 on red sandy loam soil and the experiment was laid out in randomized complete block design (RCBD) with factorial concept and replicated thrice. There were 15 treatment combinations involving three intercrops and five weed management treatments. Result: The results revealed that intercropping of maize with cowpea has recorded significantly higher grain yield (5842 kg/ha), stover yield (7035 kg/ha) and total nutrients uptake (99.53, 27.37, 96.95 kg/ha NPK, respectively). Among the chemical weed management practices, pre-emergence application of pendimethalin 30% EC @ 1.50 kg a.i./ha has recorded significantly higher grain (6589 kg/ha), stover yield (8033 kg/ha), maize equivalent yield (8860 kg/ha), total nutrients uptake (112.81, 31.05, 109.88 kg/ha NPK, respectively) and B:C ratio (3.35) compared to other weed management practices.

SUMMARYA small-plot experiment on sandy loam soil at Woburn tested the effects of subsoiling by hand and of incorporating a large dressing of P and K fertilizer into the subsoil.Ths treatments were applied once in 1973 and their effects were assessed from 1974 to 1977 on the yields of, and N, P, K uptakes by, barley, potatoes, wheat and sugar beet grown in rotation. All crops were present each year and all plots received annual seedbed dressings of N, P and K appropriate to the crop. Dolomitic limestone was applied once in the rotation. The effects of the treatments on P soluble in 0·5 M-NaHCO3 and exchangeable K in surface and subsoils were measured.Subsoiling alone increased the 4-year mean yield of wheat by 21%, of barley by 24% and of sugar from sugar beet by 11%. Mean yield of potatoes was unaffected.Incorporating P and K into the subsoil increased the mean yield of potatoes by 16% and further increased mean yield, in addition to the effect of subsoiling, of barley by 20% and of sugar by 4%. Mean yield of wheat was not further affected.
