PRE-RICE GREEN MANURING ON THE GROWTH AND YIELD OF BINA DHAN7 (Pages : 19 - 22)

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during Aman season of 2013 to study the effect of pre-rice green manure (GM) on the growth and yield of BINA dhan7. To undertake field trial with GM, five treatments were chosen: Fallow (No GM), GM with Deshi Dhaincha (Sesbania aculeata), African Dhaincha (Sesbania rostrata), Black gram (Vigna radiata) and Mungbean (Vigna mungo). After chopping GM at 50 days, short duration T. Aman rice BINA dhan7 was planted. For T. Aman there were nine treatment combinations: T1 (No GM + 100%RDN), T2 (Sesbania aculeata + 75%RDN), T3 (Sesbania aculeata + 50%RDN), T4 (Sesbania rostrata + 75%RDN), T5 (Sesbania rostrata + 50%RDN), T6 (Vigna radiata + 75%RDN), T7 (Vigna radiata + 50%RDN), T8 (Vigna mungo + 75%RDN) and T9 (Vigna mungo + 50%RDN). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The recommended fertilizer doses were used to supply N, P, K and S from Urea, TSP, MoP and gypsum, respectively. Among the yield contributing characters the panicle length and grains/panicle differed significantly due to different treatments which resulted in significant effect on the grain and biological yields of BINA dhan7. However, the other yield components and straw yields were statistically similar. The highest grain yield was found in T2 (Sesbania aculeata + 75%RDN) which was statistically similar to T6 (Vigna radiata + 75%RDN) and the lowest grain yield of 4125 kg ha-1 was found in T8 (Vigna mungo + 75%RDN). The straw yields were identical in all the treatments. The N uptake by BINA dhan7 was also influenced by different treatments. The overall results indicate that use of Sesbania aculeata or Vigna radiata as pre-rice green manure with 75% recommended dose of nitrogen fertilizer could be recommended for higher production of BINA dhan7 in Aman season.
