Effect of zinc supply on growth, yield and chemical characteristics of chick pea (Cicerarietinum L.) varieties

The experiment was conducted during rabi 2016–17 and 2017–18 at Students Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology Kanpur-2. The experiment was applied Factorial Randomized Block Design with three replication, four varieties and four treatments. The chick pea varieties viz., V₁,(KWR 108), V₂(KGD 1168), V₃, (Udai) and V₄ (pragati) with four different doses of ZnS0₄ viz., T₁, (Control), T₂, (2.5kg/ha), T₃,(5.0kg/ha) and T₄ (7.5kg/ha) as soil applied, then total treatment 16 at different stages and at harvest. Among these dose of ZnS0₄ (5.0 kg/ha) was increased maximum plant height (cm/plant), number of primary branches, net assimilation rate, number of pod per plant, biological yield(hg/ha), seed yield (kglha)and starch per cent in seed. Result revealed that application of 5kglha ZnS0₄ were significantly increase all above observation in comparison to other varieties and control (Zn 0 kg/ha) at both the year. However application of ZnS0₄ @S kg/ha on chick pea produce significantly maximum seed yield in comparison to control. Amongthe variety V₁ (KWR108) was increased in comparison to other variety.
