SEEDLING RAISING METHOD FOR PRODUCTION OF TRANSPLANTED MAIZE (Pages : 6 - 13)
MRITYUNJOY BISWAS, NAJRUL ISLAM, S ISLAM AND MASOOD AHMEDThe experiment was conducted at the Regional Agricultural Research Station, Jamalpur during the Rabi season 2002?2003 to find out suitable seedling raising method for early plant establishment of maize thereby producing higher grain yield There were two varieties viz. BARI maize?6 and Pacific?11 as main plot treatment and seven seedling raising methods viz. direct planting of seed (Dp), dry bed nursery (M1), compost nursery (M2), mud cake nursery (M3), poly bag nursery (M4) cup nursery (M5) and dapog nursery (M6) as a sub plot treatment in the split plot design. Fifteen?day old seedlings were grown in different seedling raising methods in the experiment. The results revealed that the variety Pacific?11 produced 17.49% higher grain yield than the composite BARI maize?6 mainly attributed by the higher number of cobs m?2 , number of grains per cob and 1000?grain weight. Seedling raising methods showed significant variation in respect of cob diameter, number of cobs per m2 , 1000?grain weight, grain yield, stover yield and harvest index. Statistically identical and the highest grain yields were obtained from both the methods M4 and M5. Grain yields of M2, M3 and M6 were also statistically identical to M4 and M5. Grain yields of M1 and Dp were statistically identical but significantly different and lower from M4 and M5. Both the varieties matured 6?7 days earlier when they were grown through planting of seedling than direct planting of seed. None of the characters differed significantly due to interaction effect of variety and seedling raising methods. Download
