摘要

2015-16冬季，在梅加拉亚邦Ri-Bhoi地区的研究生学院农场进行了田间试验，研究了两种不同有机地膜对rajma品种的影响。试验采用分割小区设计，3个主小区处理(地膜处理)和4个子小区处理(拉吉马品种)，重复3次。在田间调查中，杂草覆盖的效果优于玉米秸秆和不覆盖。杂草覆盖下出苗率为89%。选择-9的株高(51.19 cm)、单株分枝数(7.84枝)、荚果长(15.05 cm)、干物质积累(1.15 kg)、荚果种子数(6.48粒)均显著高于其他3个品种。杂草覆盖的产量为2.37 t ha-1，其次是玉米秸秆覆盖(2.22 t ha-1)和不覆盖(2.05 t ha-1)。杂草覆盖收获指数最高，达41.09%，其次是玉米秸秆覆盖。选择9的平均产量为2.52 t hm -1，显著高于其他3个品种。

Performance of rajma (Phaseolus vulgaris) cultivars under organic mulches in Meghalayan Plateau of North Eastern India

A field experiment was conducted at college of postgraduate studies farm during winter season of 2015-16 in Ri-Bhoi district, Meghalaya to study the effect of two different organic mulch on rajma cultivars. The experiment was laid out in a split plot design with three main plot treatments (mulching practices) and four sub-plot treatments (rajma cultivars) and replicate thrice. It was recorded during this field investigation, that the performance of weed mulch was better over maize stover and no mulch. The emergence percentage (89%) was better under weed mulching. The plant parameters, viz., plant height (51.19 cm after 60 DAS), number of branches per plant (7.84 after 60 DAS), pod length (15.05 cm), dry matter accumulation per meter square (1.15 kg), number of seeds per pod (6.48) was found significantly higher for the cultivar Selection-9 over remaining three varieties. Yield of 2.37 t ha-1 was recorded for weed mulch, followed by maize stover mulch (2.22 t ha-1) and no mulch (2.05 t ha-1). Similarly, weed mulch registered highest harvest index of 41.09% followed by maize stover mulch. The average yield of Selection-9 was found to be 2.52 t ha-1 which was higher significantly over other three cultivars.
