A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka, Bangladesh during December 2013 to April 2014 to evaluate the effect of phosphorus (P0: 0 kg TSP ha-1, P1: 100 kg TSP ha-1, P2: 175 kg TSP ha-1, P3: 250 kg TSP ha-1) and potassium (K0: 0 kg MoP, K1: 60 kg MoP ha-1, K2: 120 kg MoP ha-1, K3: 180 kg MoP ha-1), and their combinations on growth and yield of soybean (Glycine max). Number of nodules plant-1, number of filled pods plant-1, number of seeds pod-1, 1000-seed weight, seed yield, biological yield and harvest index increased significantly up to 175 kg ha-1 TSP. On the other hand, numbers of nodules plant-1, number of filled pods plant-1, length of pod, number of seeds pod-1, 1000-seed weight, seed yield, stover yield and biological yield were enhanced significantly up to 120 kg ha-1 MoP. The treatment of combined phosphorus @ 175 kg ha-1 and potassium @ 120 kg MoP ha-1 depicted the highest number of filled pods plant-1 (63.00), length of pod (3.16 cm), number of seeds pod-1 (3.11) vis a vis the highest (3.67 t ha-1) seed yield. Thus, the combined application of 175 kg ha-1 TSP and 120 kg ha-1 MoP could be the optimum for getting maximum yield of soybean.Bangladesh Agron. J. 2016, 19(1): 99-108

An adequate supply of phosphorus (P) is important for the proper growth and yield of lentil, particularly in poor fertile soil. As such an experiment was carried out to evaluate the effects of phosphorus (P) fertilizer application on growth, yield, and yield components of lentil at the agronomy research field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during 2013-201. Four lentil varieties (BARI Masur-4, BARI Masur-5, BARI Masur-6, and BARI Masur-7) and four levels of P (0, 20, 40 and 60 kg P2O5 ha-1) were used in this experiment as treatment variables. Interaction of cultivar and P levels showed a significant influence on all the plant characters studied except plant height and branch production. The highest seed yield (1.98 t ha-1) was obtained from the combination of BARI Masur-7 with 40 kg P2O5 ha-1, and the lowest (1.08 t ha-1) was from BARI Masur-5 with 0 kg P2O5 ha-1. Addition of P fertilizer beyond 40 kg ha-1 decreased seed yield irrespective of varieties. Results revealed that the application of P fertilizer offers a large scope for obtaining a higher yield of lentil in Bangladesh. However, the application of P fertilizer at the rate of 40 kg P2O5 ha-1 would be the optimum for achieving higher yield irrespective of varieties. Bangladesh Agron. J. 2020, 23(1): 29-36

An experiment was conducted at the Agronomy Field of Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from November 2011 to March 2012 to evaluate the performance of prilled urea and urea super granules (USG) on the growth and yield of wheat varieties. The experiment comprised of four wheat varieties viz., BARI Gom 21, BARI Gom 24, BARI Gom 25 and BARI Gom 26, and five nitrogen (N) levels viz., control (no Nitrogen), 84 kg ha -1 N from USG, and 30, 50 and 70 kg N ha -1 from prilled urea i.e., 67, 112 and 155 kg urea ha -1 . The experiment was laid out in a split-plot design with three replications where wheat varieties were placed in the main plot and nitrogenous fertilizers in sub-plots. Experimental results indicated that different varieties had the significant effect on plant height, number of tillers and dry weight plant -1 , and number of grains spike -1 , grain and straw yield, and harvest index. The variety BARI Gom 24 produced the highest grain yield (2.49 t ha -1 ) that mainly attributed by the maximum number of spikes plant -1 , number of grains spike -1 and 1000-grain weight. Among the different nitrogenous fertilizers 84 kg N ha -1 from USG (1.8 g) gave the highest grain yield (2.69 t ha -1 ) due to the maximum number of spikes plant -1 , maximum number of grains spike -1 and 1000-grain weight. The variety BARI Gom 24 produced the highest grain yield (2.80 t ha -1 ) with 80 kg N ha -1 from USG application.
