Abstract:
To study the effect of vermicompost and zinc levels on 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 7.5 ha^-1 and 6.0 kg Zn ha^-1, respectively increased significantly (P=0.05) the number of seeds per pod, grain yield and zinc uptake by grain 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 number of seeds per pod, grain yield and zinc uptake by grain of greengram. The application of vermicompost @ 7.5 t ha^-1 and 4.0 kg Zn ha^-1 along with the recommended dose of fertilizer results in significantly (P=0.05) higher productivity of greengram under Typic Ustipsamment soil.
