Development of Fertilizer Recommendation for Blackgram in Charland of Pabna, Bangladesh

摘要

The experiment was conducted at charland of Charsadipur in Pabna district under AEZ-11 during Khrif season of 2014 and 2015 to determine appropriate fertilizer dose for enhancing yield of blackgram as well as to increase farmers’ income. The experiment was laid out in a randomized complete block design with four dispersed replications. Eight fertilizer packages, viz.Tsub1/sub: Nsub20/subPsub15/subKsub6/subSsub9/subZnsub2/subkg hasup-1/sup(STB), Tsub2/sub: Nsub25/subPsub15/subKsub6/subSsub9/subZnsub2/subkg hasup-1/sup, Tsub3/sub: Nsub25/subPsub19/subKsub6/subSsub9/subZnsub2/subkg hasup-1/sup, Tsub4/sub: Nsub25/subPsub15/subKsub8/subSsub9/subZnsub2/subkg hasup-1/sup, Tsub5/sub: Nsub20/subPsub19/subKsub8/subSsub9/subZnsub2/subkg ha-1, Tsub6/sub: Nsub25/subPsub19/subKsub15/subSsub9/subZnsub2/subkg ha-1, Tsub7/sub: Nsub15/subPsub11/subKsub5/subSsub7/subZnsub1.5/subkg ha-1and Tsub8/sub: Native nutrients (control) were tested on blackgram. Fertilizer package of Nsub25/subPsub19/subKsub15/subSsub9/subZnsub2/subkg ha-1 (Tsub6/sub) enhanced crop growth and yield of blackgram in both the years. Maximum seed yield of blackgram (1.43t hasup-1/supin 2014 and 0.97 t hasup-1/supin 2015) was obtained with Nsub25/subPsub19/subKsub15/subSsub9/subZnsub2/subkg hasup-1/sup(Tsub6/sub), which was 80 and 147% more than the control in 2014 and 2015, respectively. The highest gross return (Tk. 82815 hasup-1/supin 2014 and Tk. 65200 hasup-1/supin 2015) and gross margin (Tk. 51125 hasup-1/supin 2014 and Tk. 32020 hasup-1/supin 2015) were also recorded from the same treatment in both the years. The results revealed that fertilizer package of Nsub25/subPsub19/subKsub15/subSsub9/subZnsub2/subkg hasup-1/supmight be recommended for getting higher seed yield of blackgram and economic return as well under charland condition of Pabna district Bangladesh Agron.
