The experiments were conducted at farmer’s field of Tukerbazer, Sylhet in Boro season and T. aman season of 2013. The initial soil properties of the experimental site are presented. Soil texture, pH, organic matter, available P and S, exchangeable K, Na, Ca and Mg were determined following standard methods. For T. Aman season, the following eight treatment combinations were tested viz. T1= Control (without fertilizer), T2= Agro-Sar (Organo-Chemical) (ASOC) @ 750 kg/ha, T3= STB (Soil Test Based), T4= T2+50% STB, T5= T2 + 60% STB, T6= T2 + 70% STB, T7= T2 + 80% STB and T8= T2 + T3. The experiment was laid out in a randomized complete block design with three replications having unit plot size of 5m x 4 m. Fertilizer doses of STB were 93 kg N, 16 kg P, 20 kg K and 10 kg S/ha, and was applied as Urea, TSP, MP and Gypsum, respectively. BRRI dhan 31 was used as test crop. Thirty day old seedlings where 2-3 seedling/hill were transplanted maintaining 20 cm x 20 cm spacing. For Boro season,: the following ten treatment combinations were tested: which are T1= FRG ’05 dose: N, P, K, S and Zn @ 123, 26, 60, 13 & 4 kg/ha, T2= Agro meal plus @ 300 kg/ha, T3= T2 + N, P, K, S @ 74, 16, 60 and 8 kg/ha, T4= ASO @ 740 kg/ha, T5= T4 + N, P, K, S @ 74, 16, 60 and 8 kg/ha, T6= Agro-Sar (Organo-chemical) (ASOC) @ 740 kg/ha, T7= T6 + N, P, K, S @ 74, 18, 36 and 8, T8= Raj Jaibo Sar @ 790 kg/ha, T9 = T8 + N, P, K, S @ 74, 20, 54 and 9 kg/ha, and T10= Control (without fertilizer). The experiment was laid out in a randomized complete block design with three replications using unit plot size of 5 m x 4 m. BRRI dhan29 was used as test crop. Fifty day old seedling where 2-3 seedling/hill were transplanted maintaining 20 cm x 20 cm spacing. Fertilizers TSP, MP, Gypsum, and Agro-Sar (Organo-chemical) were applied at final land preparation in the both experiments. Urea was applied into three equal splits like 1/3 basal, 1/3rd maximum tillering stage and the remaining 1/3rd at panicle initiation stage. Intercultural operations were done when it was required. At maturity, the crop was harvested from 5 m2 area for grain and straw yield and grain yield was adjusted to 14% moisture content. The plant height, number of tiller, number of panicle, filled and unfilled grain per panicle and grain & straw yield were recorded. The data were analyzed following randomized complete block design and mean separation was done by DMRT. Finally, economic analyses were done for net benefit and marginal rate of return.
