Abstract:

Two experiments were conducted at farmers’ field, Tukerbazer, Sylhet during T. aman season 2011 and Boro season 2012 in order to test the integrated effect of different organic manures and inorganic fertilizers on the growth and yield of wetland rice. In T. aman season eight treatments combinations were: T1= Control, T2= Agro-Sar Organic (ASO) @ 750 kg ha-1, T3= Soil Test Based (STB), T4= T2+50% STB, T5= T2 + 60% STB, T6= T2 + 70% STB, T7= T2 + 80% STB and T8= T2 + T3. BRRI dhan31 was used as test crop. In Boro season ten treatments combinations were: T1= Fertilizer Recommendation Guide 2005 dose: NPKSZn @ 123, 26, 60, 13 and 4 kg ha-1, T2= Agro meal plus @ 300 kg ha-1, T3= T2 + NPKS @ 74, 16, 60 and 8 kg ha-1, T4= ASO @ 740 kg ha-1, T5= T4 + NP KS @ 74, 16, 60 and 8 kg ha-1, T6= Agro-Sar (ASOC) @ 740 kg ha-1, T7= T6 + NPKS @ 74, 18, 36 and 8, T8= Raj Jaibo Sar @ 790 kg ha-1, T9 = T8 + NPKS @ 74, 20, 54 and 9 kg ha-1, and T10= Control (No fertilizer). BRRI dhan29 was used as test crop. The experiments were laid out in a Randomized Complete Block Design with 3 replications. In T. aman season maximum grain yield (3.87 t ha-1) was recorded in treatment T7 (ASO @ 750 kg ha-1 + 80% STB). In Boro season highest grain yield (7.41 t ha-1) was obtained in treatment T5 (ASO @ 740 kg ha-1 + NPKS @ 74, 16, 60 and 8 kg ha-1). The organic fertilizer ASO @ 750 kg ha-1 in combination with 50% reduced rate of chemical fertilizer on STB at T. Aman season and ASO @ 740 kg ha-1 in combination with 50% reduced rate of chemical fertilizer on FRG’05 dose at Boro season produced substantially higher yield.
