ThesisItem Open Access Response of Blackgram varieties to different NPK doses in Bundelkhand region of U.P.(Department of Agronomy College of Agriculture Banda University of Agriculture & Technology, Banda, U.P., 2023-08-26) Swati Maurya; Aniket Hanumant KalhapureAn agronomic investigation to study the response of blackgram varieties to different NPK doses was conducted during kharif season of year 2022-23 at college of agriculture research Unit in Banda University of Agriculture and Technology, Banda (U.P.- 210001). The experiment was laid out in split plot design with three replications. Three varieties (viz. Azad-3, IPU 10-26 and IPU 11-02) were allocated to main plots; whereas three NPK doses (viz. 75%, 100% and 125% recommended dose of NPK) were allocated in sub plots. Higher growth attributing characters at different crop stages (viz. final plant stand, plant height, number of branches, leaf area index, plant dry matter and number of nodules) and yield attributing characters at harvest (viz. number of pods plant, pod length, number of grain pod and test weight) were produced in blackgram variety IPU 10-26 with 100% recommended dose of NPK over rest of the treatments. Similarly, higher grain and stover yield, along with highest harvest index and B:C ratio was recorded in variety IPU 10-26 with 100% recommended dose of NPK as compared to all the other treatments. However, yield parameters viz. number pod per plant, number of grains per pod and test weight along with grain and stover yield was observed equivalent in 125% and 100% recommended dose of NPK in a single season of study. Higher net monetary return and B C ratio was recorded in IPU 10-26 with 100% recommended dose of NPK
