Abstract

A field experiment was conducted during the rainy (khurifl season of 1988 -and 1989, having intercropping systems and weed-control treatments in randomized block design. Intercrop cowpea [Vigna unguiculata (L.) Walp.] effectively suppressed weed growth, arrested nutrient depletion and resulted in significant increase in yield attributes and yield of pigeonpea [Cajunus cajan (L.) Millsp.] in both the years. The eirect of greengram (Phaseolus radiatus L.) was slightly lower than of cowpea in wet year but minor in drought year. Hand-weeding and tank mix of imazethapyr + pendimethalin effected significant decrease in weed population, weed dry weight and nutrient depletion and conspicuous increase in yield attributes and yield of pigeonpea in both years. Their application resulted in higher net return, net returnlmpees and benefit : cost ratio. Intercropping systems generated higher return than sole cropping in both the years.

8 of 11 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
