“…Kushare et al (2009) stated that because of increasing dry matter accumulation with each increasing level of nitrogen and phosphorus, partitioning of dry matter into reproductive parts resulted in significantly higher number of spikes m -2 and number of grains spike -1 . Similar results were also obtained by El-Gizawy (2009) ; El-Razek and El-Sheashtawy (2013) and Shende et al (2020).…”

Scarce availability of chemical fertilizers threatens sustainability of wheat production in Nepal. Combined application of chemical and biofertilizer can reduce chemical fertilizer and enhance the yield under limited fertilizer availability. A field experiment was carried out to assess the combined application of chemical and biofertilizer on the growth and yield of spring wheat at Rampur, Chitwan from November 2020 to April 2021. The experiment was laid out in strip plot design with four nitrogen and P2O5 levels (0, 50, 75 and 100% of recommended dose) in vertical plots and three biofertilizer application methods (not applied, seed applied and soil applied) in horizontal plots with three replications. The research results revealed significant interaction between nitrogen and P2O5 levels and biofertilizer application methods. The highest grain yield (4624.48 kg ha-1) of wheat was obtained with 100% levels of N and P2O5 with soil applied biofertilizer at par with 75% levels of N and P2O5 with soil applied biofertilizer (4457.54 kg ha-1). The total nitrogen uptake was higher in biofertilizer applied wheat as compared with no application of biofertilizer although statistically not significant. The yield increment in 100% and 75% N and P2O5 levels with soil applied biofertilizer over same level N and P2O5 with no biofertilizer application were 10.96% and 29.60% respectively. The higher gross return, net return and B:C ratio were obtained with 75% and 100% N and P2O5 levels with soil and seed applied biofertilizers. The result indicates that 25% recommended dose of N and P2O5 could be reduced by soil application of biofertilizer without compromising the grain yield of wheat. Int. J. Appl. Sci. Biotechnol.

“…Peng et al (2011) and Wu et al, (2012) reported that rice straw biochar contains nutrients beneficial for plants such as nitrogen, carbon and silicon. Significant effect of N, P, and K fertilizer levels on plant height, yield and its components was observed by Khan et al, (2012) and Shende et al (2020). The increase in these traits in response to application of N fertilizers is probably due to the enhanced availability of nitrogen which enhanced more leaf area resulting in higher photo assimilates and rapid conversion of synthesized carbohydrates into protein and consequent to an increase in the number and size of growing cells, resulting ultimately in an increased number of tillers and grain yield (Singh and Agarwal, 2001).…”

The present study was conducted during the 2019/2020 and 2020/2021 growing seasons at Shandaweel agricultural research station, Sohag governorate to study the individual and combined effect of three rates of rice straw biochar and four rates of N, P and K mineral fertilizers on the agronomic traits, nutrient contents in leaves and grains, protein and carbohydrates content in grains of wheat cultivar Misr 3 as well as on some soil properties. The experiment design was a split plot with three replications, whereby biochar treatments occupied the main plots at a rate of 0, 5 and 10 t ha -1 , while the sub plots were devoted to mineral N, P and K fertilizers at a rate of 0, 50, 75 and 100% of the recommended dose. Results revealed that the combined application of 10 t ha -1 biochar and 100% N, P and K fertilizers treatment recorded the highest values for all the studied traits as well as improving the soil properties compared to other treatments. Furthermore, the addition of 10 t ha -1 biochar with 75% and 100% of N, P, and K fertilizers significantly improved grain yield by (11.13 and 18.80%) in the first season and by (7.69 and 16.62%) in the second season, respectively compared to the application of 100% of N, P and K fertilizers without biochar. In conclusion, biochar can be used to reduce using all chemical fertilizers (N, P, and K) by 25% as well as enhancing soil fertility and wheat productivity.

BACKGROUNDWater and nutrients are two main determinants of wheat yield, which are vital for maintaining high crop yields. In the present study, the effects of water and phosphate fertilization on wheat yield, photosynthetic parameters, water productivity and phosphate use efficiency were investigated. Five dryland wheat cultivars from the 1940s to the 2010s that are widely cultivated in Shaanxi Province, China, were used. Experiments were conducted from 2019 to 2022 using two irrigation levels (normal rainfall and no precipitation after the reviving stage) and two phosphorus application levels (0 and 100 kg ha−1).RESULTSCompared with old cultivars (‘Mazha’), the grain yield of modern cultivars (‘Changhan 58’) was 89.24% higher and was closely correlated with chlorophyll index, leaf area index, photosynthetic rate and tillers. With the replacement of cultivars, the phosphorus content, water potential and phosphatase activity of wheat leaves increased. Considering water–phosphorus interactions, the water use efficiency and phosphorus use efficiency of wheat showed a significant positive correlation.CONCLUSIONOur findings indicate that modern wheat cultivars are more responsive to phosphorus. Further analysis revealed that modern varieties have evolved two phosphorus absorption strategies in response to phosphorus deficiency – namely, the formation of a phosphorus supply source, which may result in larger numbers of green organs; and an increase in phosphorus sinks, which tended to activation and transport of plant phosphorus. Our results may thus contribute to water conservation, increased yields and the development of strategies for efficient phosphorus fertilization. © 2024 Society of Chemical Industry.
