Abstract

A field experiment was conducted for three years to study the effect of sowing dates, mulching and seed rates on nutrient uptake and productivity of soybean under irrigated conditions in sub-humid Punjab on a silty clay loam soil which was low in available N, medium in available P and available K. The experiment was conducted in a split plot design with the combination of three sowing dates and mulch in main plots and three seed rates in sub-plots with three replications on fixed site. The results revealed that sowing on June 30 and mulching recorded the highest number of pods plant-1.There was no significant influence of seed rates on yield attributes. Seed yield also remained at par under different sowing dates, mulching and seed rate treatments. Stover yield however, was significantly higher under the earlier sowing dates and mulching. Highest total N uptake was observed under June 30 sowing date whereas total P and K uptake was highest in May 20 sowing date. No significant effect of mulching was observed on total N and K uptake. Among seed rates maximum total N uptake was observed under 75 kg seed ha-1. The results suggest that soybean performed better when sown with 60 kg seed rate ha-1 on June 30 and mulched with wheat straw.

印度旁遮普省半湿润地区播期、覆盖和播种量对大豆养分吸收和生产力的影响

进行现场试验了三年学习的影响播种日期、覆盖和种子利率在灌溉条件下大豆的营养吸收和生产力在半湿润旁遮普粉砂质粘壤土土在可用低N,可用介质P和k .可用实验是在分裂阴谋进行设计组合的三个播种日期和地膜主要情节插曲和三个种子率三个固定的网站上复制。结果表明，6月30日播种和复盖时植株1号的荚果数最高。籽粒率对产量性状无显著影响。不同播期、覆盖和种子量处理的种子产量基本相同。然而，较早播种和覆盖的秸秆产量显著较高。6月30日播期全氮吸收量最高，5月20日播期全磷、全钾吸收量最高。覆盖对全氮和全钾吸收无显著影响。各种子速率下，总氮吸收量在75 kg种子hm -1时最大。结果表明，6月30日播种60 kg播种率hm -1，覆盖麦秸时，大豆表现较好。
