ABSTRACT

Research was conducted at the Parasankulum located in Vavuniya district, to study the effect of growth and yield performances of mung bean (Vigna radiata L.) under different mulching practices during the period of February to May 2016. Three different mulching treatments such as live mulch with sun hemp (T1), dry mulch ie paddy straw mulch (T2) and No mulch (T3) were tested in randomized complete block design with four replicates. Size of each plot was 3.5 m x 2 m and mung bean sowing was done by hand at a depth of 2 cm and thinned out at 5-7 days after germination. The soil properties, plant growth, yield components, dry weight of weeds and their counts were recorded. The data were analyzed by using SAS 9.1 package. In weed composition and biomass, both were lowest in the live mulch treatment than other treatments. In growth parameters, there was a significant difference between mulched treatments and no mulched treatment, but there was no significant differences among the mulched treatments. The yield components of mung bean significantly different among treatments and highest yield was observed in live mulch. The live mulched treatment produced the highest 1000 grain weight (89.43 g) in comparison to the no mulched treatment (86.43 g). Significant yield increase was observed in live mulched treatment (1.86 tons /ha) compared to the other treatments. Profit from live mulched treatment also the highest than other treatments. Mulched treatments produced highest yield compared to no mulched treatment. Among mulched treatments, the live mulch produced the highest yield. Therefore, live mulch was the best mulch than straw mulch in weed suppression, crop yield and profit.
