Effect of Different Sources of Nitrogen and Phosphorus and Application Methods on Yield and Quality of Hybrid Pearl Millet

Abstract

Due to high yielding and short duration hybrid pearl millet got populized in last few years under pearlmillet-mustard/wheat cropping system but its required higher nutrient as compared to composite varieties but farmers apply only N and little amount of  P which is responsile for low yield therefore,  the present study was carried out during kharif 2021 and 2022 with 12 treatments of different sources which are chemical fertilizers, vermicompost (VC) and bio-fertilizers(Azotobacter and PSB) and application methods (seed treatment, soil and foliar application) of nitrogen and phosphorus in RBD with 3 replications. The resulted indicated that the application of 100% Nitrogen and Phosphorus by chemical fertilizers produced significantly higher yield attributes (length and girth of cobs) and yield parameter (grain and stover yield and harvest index) of pearlmilletas compared to 50 and 75% NP treatments. Maximum grain yield 29.87 q ha-1) was noted with integration of chemical, organic and bio fertilizers (75% NP + Seed treatment by Azoto + PSB + 5 t VCha-1) which was significantly higher over rest of all other treatments. Minimum yield parameters were noted with control (0 % NP).  Application of vermicompost @ 5 t ha-1 with 75 per cent of NP and inoculation of Azotobacter and PSB improved test weight and protein content.
