Abstract:
A field experiment was conducted at the College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari to study the effect of spacing and cobalt application on kabuli chickpea (Cicer kabulium L.) cultivars under South Gujarat condition. The treatments of the study included eighteen treatment combinations consisting of three varieties (V₁- Virat, V₂- Kripa and V₃- PKV2), two spacings (S₁- 45 cm x 10 cm and S₂- 60 cm x 10 cm) and three cobalt application methods (C₁- Seed priming at 1 ppm, C₂- Seed treatment at 1 g kg^-1 seed and C₃- Foliar spray at 0.01%). The treatments were evaluated with factorial randomized block design (FRBD) with three replications. For estimation of N, P, K and Co content in grain and stover were determined by Modified Kjeldal’s method, Vanadomolybdo phosphoric acid colorimetric method, Flame photometric method and 0.005 M DTPA (AAS) methods respectively. Nutrient content was multiplied by yield to calculate nutrient uptake (kg ha^-1). Available N, P, K and Co were determined by alkaline permanganate method, Olsen’s method, Flame photometric method and 0.005 M DTPA (AAS) method respectively. Sowing of Kripa variety (V₂) with spacing 60 cm x 10 cm (S₂) and application of cobalt as a foliar spray at 0.01% (C₃) had significant effect on N, P, K and Cobalt content in seed and stover and their uptake except foliar spray at 0.01% (C₃) which remained non-significant. Cultivar PKV2 (V₃) and other two factors had significant effect on available N, P, K and CO in soil after harvest.
