Abstract

A field experiment was conducted at the crop farm, Eastern University, Sri Lanka to study the effect of vermiwash application on growth and yield of green gram (Vigna radiata). The experiment was laid out in a Randomized Complete Block Design with five treatments having four replicates. The treatments were recommended inorganic fertilizer (T1) and ½ doses of recommended basal and top dressing with different concentration of vermiwash; 25%(T2), 50% (T3), 75% (T4) and 100% (T5). Vermiwash was applied at once in two weeks and data were recorded at 2nd, 4th, 6th, 8th weeks after planting (WAP). The results revealed that number of branches, days for 50% and 100% flowering, number of pods per plant and number of seeds per pod were significantly (P<0.05) varied at 8th week after planting and it was high in T4. Minimum duration of 30 days and 35 days were taken by T4 for 50 % and 100 % flowering respectively. Foliar application of vermiwash increased the root length and dry weight of root was high in T5 followed by T4 at 2nd, 4th, 6th and 8th WAP. However, there was no significant variation between T5 and T4 in dry weight of shoots. Further, plant height, dry weight of roots, leaf area index and yield components are significantly influenced (P<0.01) by application of vermiwash. Yield in T4 was 2.3 and 2.5 times greater than control at 6th WAP and 8th WAP, respectively. This study suggests that application of ½ doses of recommended basal and top dressing supplemented with 75% vermiwash (T4) would be more suitable for cultivation of green gram in sandy regosol.
