Abstract:

An experiment was conducted at saline agro-ecosystem of Burir Char Union, Barguna District during January to June 2018, with a view to find out  the fertilizer management for maximizing soybean (Glycine max L.) production in saline agro-ecosystem was laid out in randomized complete block design consisted of three varieties of soybean and four levels of fertilizer doses with three replications. Three varieties of soybean viz. BARI Soybean-5, BARI Soybean-6 and Binasoybean-3 and  four fertilizer levels viz. T1 = 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B (Soil test based fertilizer); T2 = 30-40-60-12-2.0-1.0 kgha-1 N-P-K-S-Zn-B (Fertilizer recommendation guide, 2012); T3 = 40-20-15-0-0-0 kgha-1 N-P-K-S-Zn-B (Farmers practices); T4 = Control native fertility were considered  which placed in a factorial randomized block design. The variety had significant influence on plant height, branches plant-1, number of filled pods plant-1, number of unfilled pods plant-1, seed yield plant-1, seed yield (t ha-1), stover yield (t ha-1). BARI Soybean-6 performed better than the other two varieties. The fertilizer doses had significant influence on plant height, branches plant-1, number of filled pods plant-1, number of unfilled pods plant-1, seed yield plant-1, 100-seed weight, seed yield (t ha-1), stover yield (t ha-1). Fertilizer doses 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B (Soil test based fertilizer) gave the maximum yield. The interaction between variety and fertilizer doses V2T1 (BARI Soybean-6 and 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B) produced the maximum yield SO, the variety BARI Soybean-6  with  fertilizer dose 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B could be suitable combination for higher yield of soybean in saline agro ecosystem of Barguna.
