Abstract

Among crop husbandry practices, wheat straw incorporation brought about a significant reduction in Cyperus rotundus population and soil solarization in Cynodon dactylon population at 20 DAS in soybean. The total monocot weed population due to these two treatments was thus significantly lower. Summer cowpea for fodder, on the contrary, recorded the highest population of Cynodon and total monocot weeds, but the population of Commelina benghalensis was zero/nil and Parthenium hysterophorus was greatly reduced. Wheat straw incorporation had significantly higher Trianthema portulacastrum population, which resulted in very high dicot and total weed population. At 40 DAS of soybean, total monocot weed distribution was almost similar to what observed at 20 DAS. However, total weed population was the lowest in soil solarization and differed significantly with others. The monocot, dicot and total weed dry weight followed similar trend as their respective population and soil solarization proved most superior. At harvest of wheat, wheat straw incorporation; however, recorded the lowest total weed dry weight comparable with soil solarization and summer cowpea for fodder. Soil solarization and wheat straw incorporation were at par with each other on soybean grain yield, but solarization recorded significantly higher grain yield than others. Repeated tillage with irrigation and summer cowpea for fodder also recorded soybean grain yield significantly higher than in control/farmers’ practice. Wheat straw incorporation and repeated tillage with irrigation being at par with soil solarization recorded significantly greater number of ear-bearing tillers and grain yield of wheat. However, soil solarization recorded the highest system productivity in the soybean-wheat cropping system closely followed by wheat straw incorporation and repeated tillage with irrigation.
