摘 要：The field experiment was conducted at Pulses Research Centre of Bangladesh Agricultural Institute (BARI), Ishurdi, Pabna, Bangladesh during rabi season of 2009 to find out the suitable management package for better plant establishment and higher yield of lentil under relay cropping. The experiment was based on three genotypes-Rajbari local, X95S-167(4) and X95S-136; two types of rice straw height-10 cm and 30 cm; three seed rates (kg/ha)-e. g., 30, 50 and 60, and three levels of fertilizer-control, 30-60-20 kg/ha of N-P 2 O 5 -K 2 O and 30-60-30 kg/ha of N-P 2 O 5 -K 2 O. The experiment was laid out in a split-split-split-plot design with three replications. Genotype was placed in the main-plot, rice straw height was in the sub-plot, seed rate was in the sub-sub-plot and fertilizer level was in the sub-sub-sub-plot. From this study, it was observed that lentil genotype X95S-136X planted with a rice straw height under 30 cm, at a seed rate of 50 kg/ha, and with a fertilizer level at 30-60-30 kg/ha of N-P 2 O 5 -K 2 O produced the highest lentil seed yield of 2,070 kg/ha and the lowest seed yield (550 kg/ha ) was obtained from genotype Rajbari local, planted with a rice straw height under 10 cm, at a seed rate of 30 kg/ha and no fertilizer. Similar result regarding seed and straw yield was also found in the farmers field. The accession X95S-136 along with improved production technologies produced the highest grain and straw yield, and net return but the lowest grain and straw yield as well as net return were obtained by Rajbari local in the demonstration field. It was also identified that, by the inclusion of lentil in the transplanted monsoon rice field, lands could be brought under lentil cultivation to enhance lentil production, provide human nutrition and also to ensure soil health improvement for sustainable production system.
