Abstract:
The effect of vermicompost and zinc levels on response study and productivity of greengram (Vigna radiata L.) in Typic Ustipsamment soil of Semi Arid Eastern Plain of Rajasthan. A field experiment was undertaken during Kharif 2016 at Agronomy Farm, S. K. N. College of Agriculture, Jobner, Jaipur (Rajasthan). The treatments comprised of four levels of vermicompost (VC) i.e. control, VC @ 2.5, 5.0 and 7.5 t ha^-1 and four levels of zinc application i.e. control, 2.0, 4.0 and 6.0 kg Zn ha^-1.The experiment was laid out in a factorial randomized block design with three replications. The increasing levels of vermicompost and zinc up to 5.0 t ha^-1 and 4.0 kg Zn ha^-1, respectively increased significantly (P=0.05) the grain and straw yield of greengram. However, the combined application of vermicompost @ 7.5 t ha^-1 and 6.0 kg Zn ha^-1 was found to record significantly higher grain and straw yield of greengram. The economic optimum level of vermicompost and zinc was found to be 4.12 t ha^-1 and 4.86 kg ha^-1 with grain yield of greengram 1158.24 and 1197.54 kg ha^-1, respectively.
