Abstract:
Integrated use of organic and inorganic fertilizers can improve crop productivity and sustain soil health and fertility. The present experiment was conducted with an objective to study the influence of application of Erythrina biomass transfer in combination with NP chemical fertilizers. Seven treatments: no input (control); Recommended NP (RNP); 50% RNP + 50% Erythrina; 25% RNP + 75% Erythrina; 75% RNP + 25% Erythrina; 100% Erythrina; 50% Erythrina were compared in a randomized complete block design replicated three times. Data on grain and biomass yield, 1000 seed weight, number of tillers per plant, and spike length were collected. The results showed that application of Erythrina and NP either combined or alone significantly improved wheat production than untreated control. Sole application of 50% E. gave equivalent wheat yield with RNP treated plots. Although not significant application of 100% Eryhrina gave a higher wheat grain yield than RNP. Biomass yield followed similar trend. The highest wheat grain yield (3453.1 kg ha-1) was record by application of 25% Erythrina along with 75 % RNP but not have statistical difference with 25% RNP +75 Erythrina, 100% Erythrina and 50% RNP +50% Erythrina. Highest and modest net benefit and Marginal rate of return were also obtained by application of 25% Erythrina along with 75% RNP and 50% Erythrina respectively. Hence, we recommend the application of 25% Erythrina +75 RNP at Chena for improved and sustained wheat production. Since the benefits of organic sources are beyond crop yield increase, 50% Erythrina could be used as an option based on the resource availability in the study area.
