Effects of Organic Manure: Amirthakaraisal and Cow Dung on Performances of Greengram (Vigna radiata) Grown in Pots

Abstract

Green gram (Vigna radiata) is an annual important pulse crop that mainly grown in tropical, subtropical and, temperate regions of Asia. Traditionally it is grown on commercial scale with synthetic fertilizer and on subsistent scale with organic manure. Amirthakaraisal is an organic liquid nutrient solution containing of N, P and K. The present study was conducted with the objective of investigating the effect of combination of Amirthakaraisal and Cow dung on the growth and yield of Vigna radiata. The experiment was conducted as a pot experiment with six treatments and ten replicates in a completely randomised design (CRD). Which was maintained in open field. The treatments are T1 -100% Amirthakaraisal, T2 - 75% Amirthakaraisal and 25% Cow dung, T3 - 50% Amirthakaraisal and 50% Cow dung, T4 - 25% Amirthakaraisal and 75% Cow dung, T5 - 100% Cow dung, T6 – control(zero treatments). Treatments were applied two week interval according to the pot area. Growth and yield parameters were measured and analysed statistically using ANOVA and means were compared with DMRT at 5% significance level.. The results proved that T3- 50% Amirthakaraisal and 50% Cow dung significantly (P < 0.05) increased the dry weight of shoot (27.27 %), , number of pods per plant (31.03 %), weight of 100 seeds (29.78 %), total yield (33.73 %) in comparison to plants without application of organic manure(T6). T3 given best results when comparing with T1, T2, T4, T5 and also T3 plants were expose their 50% flowering 30 days after planting compared with other treatments. Therefore, it could be concluded with the final yield of Vigna radiata that application of 50% Amirthakaraisal and 50% Cow dung to soil increased the growth and yield performance of Vigna radiata.
