’N-Serve’ has been shown to reduce losses of applied N-fertilizer and thereby increase fertilizer N-utilization by plants. This study was undertaken to test the effects of ’N-Serve’ on fertilizer N efficiency in oilseed rape production and quality. Field experiments were conducted on two chernozemic soils over 4 yr in Manitoba. The oilseed rape cultivars Tower (Brassica napus L.) and Torch (B. campestris) were used in the study. Spring and fall applied ammonium nitrate, urea and fluid-N, with and without ’N-Serve’ delayed flowering and increased the herbage yield of both oilseed rape cultivars. The number of days from full pod to maturity was increased with application of N fertilizers, but the number of days from flowering to full pod was constant. Increased herbage yield and total plant N at flowering was reflected in increased seed yield and meal protein content, but decreased oil content. ’N-Serve’ applied with and without N fertilizer reduced oil content and oil yield. However, when ’N-Serve’ was applied in the fall with urea and fluid-N it improved their efficiency, resulting in higher seed yields and meal protein content equivalent to that of spring applications. ’N-Serve’ used with fall applied ammonium nitrate or with all three sources of spring applied N had no similar effect. It is concluded that ’N-Serve’ should not be applied to oilseed rape, mainly because of its negative effect on seed oil content.Key words: Oilseed rape, ammonium nitrate, urea, fluid-N, chernozemic soil, protein, oil

AbstractManipulation of organic wastes and their composts as a source of organic matter (OM) and nutrients is imperative for sustainable agriculture. Further, the fortification of composts with chemical fertilizer enhances agronomic effectiveness of both by reducing the amount of fertilizer and improving the quality of compost. The present study aimed to explore the potential of organic and chemical nutrient sources with their optimal application and integration for sustainable wheat production. Accordingly, waste fruits and vegetables were collected, dried, ground and processed in a composting vessel. During the enriched composting, waste material (300 kg) was fortified with 30 kg N, i.e. 25% of the standard rate (120 kg N ha−1) of N fertilizer. Treatments for both greenhouse and field experiments using wheat (Triticum aestivumL.) included: control (without any compost or N fertilizer), compost (non-enriched), fertilizer N 120 (120 kg N ha−1), nitrogen-enriched compost (NEC), NEC+N 30 (30 kg N ha−1) and NEC+N 60 (60 kg N ha−1). Application rate of composts (non-enriched or enriched) was 300 kg ha−1in the respective treatments. Phosphorus and potassium fertilizers were applied at 90 kg P2O5ha−1and 60 kg K2O ha−1, respectively in all treatments. The crop was grown to maturity, and data on wheat growth and yield attributes were recorded. Application of NEC significantly improved the growth, yield and N, P and K contents of wheat compared with compost and control treatments. The performance of NEC+N 60 was statistically similar to that of fertilizer N 120. Economic analysis also revealed the superiority of NEC+N 60 over other treatments in terms of net return and relative increase in income; however, the value/cost ratio was highest with NEC alone. For effective and economical use of N fertilizer, it is suggested to integrate N fertilizer at reduced rates with NEC. Through enriched compost, application rates can be decreased from tonnes to kilograms per hectare, and dependence on chemical fertilizer can be reduced to a certain extent. So the approach is farmer friendly as it lowers compost application rates, and is economically acceptable as it saves N fertilizer. It is also environmentally sustainable due the recycling of organic waste and possible reduction of N losses to the environment. Thus, the study has wide application in the global environment and fertilizer market.

Field experiments on ordinary black soil were conducted in 2018-2021 in the Rostov region. The object of research was a variety of winter barley Master. The predecessor is corn for grain. Bacte-rial preparations developed at the All-Russian Institute of Agricultural Microbiology (VNIISHM) in St. Petersburg contain strains of associative microorganisms-nitrogen fixators: Mizorin, Ri-zoagrin, Extrasol. They were applied to barley seeds in the pre-sowing period. It was found that the use of Mizorin (600 g /ha) for seed treatment before sowing against the background of a near-sowing application of nitrogen-phosphorus fertilizer in the form of a mixture of ammophos and ammonium nitrate at a dose of N30P30, nitrogen fertilization by a scattered surface method with ammonium nitrate at a dose of 30 kg/ ha of the active substance increased the increase in grain yield on average for 3 years compared with the control variant by 0.71 t/ ha or by 14.4%. The use of the biological preparation Mizorin without mineral fertilizers against the background of natural soil fertility increased the yield compared to the control variant by 0.31 t /ha or by 6.3%. On av-erage, in 2019-2021, the protein content in winter barley grain in the control variant was 10.7%, which provided a protein harvest equal to 528 kg/ha. Against the background of nitrogen-phosphorus fertilizers at a dose of N30P30 and nitrogen fertilizing at a dose of 30 kg / ha, the max-imum increase in protein content was obtained in the variant with the use of Mizorin, which compared to the control variant was 1.1%, while the protein harvest increased by 138 kg/ha or 26.1%.

Field experiments were conducted over four growing seasons in southern Alberta to develop improved irrigation and nitrogen fertilizer recommendations for soft white spring wheat (Triticum aestivum L.). Irrigation to provide available water in the root zone to maturity maintained acceptably low protein content of soft wheat fertilizer-N plus soil test NO3-N levels from 140 to 208 kg ha−1. Nitrogen fertilizer increased protein content in all 4 yr of the study and increased yields each year except 1981 when the soil contained a high level of NO3-N. The protein content was not raised above the level considered acceptable for the domestic Canadian market (10.5%, moist basis) unless fertilizer rates in excess of the economic optimum level were applied. Fertilizer-N response curves were developed for each cultivar, irrigation treatment, and year combination. These were used to show the relationship between yield and the level of fertilizer N plus soil NO3-N which would result in economic optimum yields of soft white spring wheat of acceptable protein content. The results suggest N rates can be increased about 30 kg ha−1 for each t ha−1 increase in the target yield of the producer.Key words: Wheat (soft white spring), Triticum aestivum L., irrigation, nitrogen fertilizer, protein, target yield

Plot trials measured the effect of fertilizers and defoliation on Hyparrhenia veld.N was the only nutrient limiting growth, and N fertilizer markedly increased the herbage yield and crude protein %. The herbage response was linear up to the highest rate used, 189 lb. N/acre, with a calculated N recovery of approximately 35%. Split fertilizer applications were only advantageous in one year out of three. The effect of N fertilizer steadily decreased at successive harvests after application, and the residual effect in a following season was transient. N fertilizers did not alter the botanical composition of the veld.

Soil moisture tension (100 and 151 mbars) and amendments (straw, peat, manure, and ammonium nitrate) on three Gray Wooded and one Dark Gray soil significantly affected yield, oil, and protein content of Target rapeseed (Brassica napus L.). Low soil moisture tension (LSMT) gave higher yields than high soil moisture tension (HSMT). In general, lower oil content and higher protein content were obtained under HSMT than under LSMT. Also, the ammonium nitrate treatment increased protein content of the grain more than the other amendments. Protein content ranged from 28.2 to 43.3% and oil content from 38.9 to 50.0%. Regression analysis revealed that protein and oil content were inversely related (R2 = 79.6%). Lowest fiber content (highest protein plus oil) was obtained with rape grown on Dark Gray, Nipawin loam soil. Ammonium nitrate (70 μg N/g soil) produced the lowest fiber content averaged over moisture tension and soil type treatments. Those treatments that helped to increase the available nitrogen supply to the crop and that increased protein contents of the grain produced the lowest fiber contents.

The objectives of this study were to investigate: (1) the effects of genotype, environment, and their interactions on the oil content (OC), protein content (PC) and grain yield (GY) of 25 varieties of winter wheat, (2) the correlations among these traits in different environments, and (3) the effects of different climatic variables and their interactions with wheat genotypes for the examined traits. The field experiments were performed on three experimental sites in Serbia in 2009/10 and 2010/11. The most variable traits were GY and PC, while the variations of OC were lower. A significant positive correlation between wheat bran OC and GY was found in one, while highly significant negative correlations between PC and GY were found in three out of six environments. The partial least square regression (PLSR) triplots for protein content, oil content and grain yield enabled us to identify favorable and limiting climatic conditions for each trait and explained 31.9%, 32.6%, and 30.4% of the total variance, respectively. Cvs. Renesansa and Zvezdana were identified as genotypes with high average values for all traits, while cvs. Bankuty 1205 and Banatka were identified as potential sources of high protein content.

Seedrow-placement of N fertilizer can save money and time, but it can cause reduced emergence and yield. From 1998 to 2000, a field experiment was conducted on a silty clay loam (Black Chernozem) soil at Melfort, Saskatchewan. The objectives were to determine the influence of placement, rate and source of N, seedrow opener and seeding depth on the emergence, yield, N uptake, and seed protein and oil content of canola (Brassica napus L. ‘Quest’). The treatments were optimum (1.5 cm) and deep (4.5 cm) seeding depths in two main plots with 17 subplots of different combinations of N sources [urea and ammonium nitrate (AN)], rates (0, 40, 80 and 120 kg N ha-1) and placements (sideband and seedrow) using two seedrow openers (knives – 2 cm spread, and shovels – 20 cm spread). Sidebanding of 40, 80 and 120 kg N ha-1 and seedrow placement of 40 kg N ha-1 increased yield, N uptake and seed protein content, had no detrimental effect on emergence, and reduced seed oil content. Compared to sidebanding, seedrow placement of 80 and 120 kg N ha-1 generally reduced emergence, yield and N uptake, with relatively severe effect at higher N rate, but had no effect on seed protein and oil content. The yield and N uptake of canola responded up to 120 kg N ha-1 with sidebanding compared to 40 kg N ha-1 for yield and 80 kg N ha-1 for N uptake with seedrow placement. Deep seeding reduced emergence, yield and N uptake in many cases, had no effect on seed protein content and reduced oil content in some treatments. At low rates of N, emergence was generally better with knives, while shovels tended to be superior at higher rates of seedrow-placed N. In general, the negative impact of seedrow placement compared to sideband placement of N was more severe with deeper seeding, higher N rate and narrower width of seedrow placement band. In summary, the findings indicated that practices that placed seed and fertilizer in a way that maximized canola emergence and minimized seedling damage from fertilizer, consistently optimized seed yield response to N fertilizer.

SUMMARYThe pH of soil cropped with ryegrass increased with calcium nitrate as a fertilizer and decreased with ammonium nitrate, especially in the mid-range of pH. Changes above pH 7·2 and below pH 4·5 were small.Yields of 4 cuts of grass given either N-fertilizer were similar over a pH range (in 0·01M-CaCl2) from 4·3 to 7·4. However, the composition of the grass and nutrient uptakes were affected by both soil pH and form of N-fertilizer.
