Effect of Liquid Manure on Growth and Yield of Summer Green Gram (Vigna radiata L. Wilczek)

A field experiment was undertaken to study the effect of different liquid manure on growth and yield of green gram during summer seasons of 2015 and 2016. The experiment was conducted at Model Organic Farm at Kalyani C block of Bidhan Chandra Krishi Viswavidyalaya Nadia under New alluvial zone of West Bengal with 8 different treatments of liquid manure i.e. (T1 = Jivamrut+FYM, T2 = Sanjivak+FYM, T3 = Panchagavya+FYM, T4 = Cow urine+FYM, T5 = Vermiwash+Cow urine + FYM, T6 = Vermiwash+FYM, T7 = Vermicompost+FYM, T8 = Control) and with three replications. The result of experiment revealed that the combined application of Panchagavya @8 kg N equivalent along with FYM @ 12 kg N equivalent (T3) exerted significant influence towards higher growth parameters like plant height, LAI and dry matter accumulation throughout the crop growth period, yield attributes like number of pod/plant, pod length, number of seeds/pod and test weight and thus achieved maximum grain yield (1085 kg/ha) and stover yield (3224 kg/ha). On the basis of field performance, it may be inferred that the treatment FYM@12 kg N equivalent at land preparation + Panchgavya @8 kg N equivalent (twice equal split applications at 30 DAS and 45 DAS through irrigation water) may be recommended as a better organic package of greengram followed by FYM @12 kg N equivalent at land preparation + vermicompost @8 kg N equivalent (twice equal split applications at 30 DAS and 45 DAS as top dressing) among all other treatments applied in the soil.
