Abstract:
Experiment was carried out at the farm of Zonal Agriculture Research Station, Shendapark, Kolhapur (M.S.), India during kharif, 2021. The experiment was laid out in randomized block design with three replication and consisted of twelve treatments. The treatment consists of different levels of RDN along with seed treatment and foliar sprays of nano nitrogen fertilizer. Variety Phule Ekadashi was used for experiment. Though the effect of nano fertilizer and different nitrogen levels on soil parameters were found non-significant still the highest values of soil pH (6.87), EC (0.26 dSm^-1) and OC (0.53%) was recorded by the treatment T₁₂ (75% RDN+ Seed treatment with 1% nano fertilizer + Foliar spray of nano fertilizer @ 0.4% at active tillering stage and 7-10 days before flowering) over initial observations. In case of nutrient availability in soil after harvest the maximum nutrient was recorded in treatment T₁₂ these are as follows N (278.67 kg ha^-1), P (48.85 kg ha^-1) and K (245.81 kg ha^-1). However, lowest nutrient availability was shown by treatment T_2. The higher cost of cultivation was recorded in treatment T₁₂ which was Rs. 26655 ha^-1 and treatment T₁₁ [75% RDN + Foliar spray of nano fertilizer @ 0.4% at active tillering stage and 7-10 days before flowering] which was Rs. 26655 ha^-1. The lowest cost of cultivation was recorded by treatment T₂ [T₁ without Nitrogen application] which was Rs. 22896 ha^-1. The T₁₂ recorded maximum values for both gross monetary returns (Rs. 53316 ha^-1) and net monetary returns (Rs. 26661ha^-1). However, treatment T₂ observed the lower figures in case of both gross monetary returns (Rs. 35784 ha^-1) and net monetary returns (Rs. 12888 ha^-1). The higher benefit: cost ratio was recorded by the treatment T₁₂ which was 2.00 and the lowest benefit: cost ratio was recorded by treatment T₂ which was 1.56.The treatment T₁₂performed good in obtaining higher grain yield of 1466kgha^-1 and straw yield of 2458 kgha^-1.
