Influence of time of sowing and plant population on the yield of Chickpea.

Chowdhury S.I.
Four dates of sowing (November 1, November 18, December 2 and December 15) and four population densities (10,20,30 and 40 plants/m(2)) were arranged in a split plot design with chickpea cv. Hyprosola as a test crop. Different populations were obtained by varying the plant to plant distance at a constant row spacing of 40 cm. Averaged over four population densities, grain yield was highest at first sowing on November 1, and showed significantly higher yield over 3rd and 4th sowing dates with no difference with that of 2nd sowing on November 18, Number of pods and branches per plant and plant height showed similar results. Although population densities 10,20,30 and 40 plants/m(2) were used the actual population stands at harvest averaged over four planting dates were 9.2, 17.7, 24.7 and 27.1 plants/m(2). The low stand at higher plant densities was due to higher mortality of plants from root rot attack. However, the grain yield data avaraged over four planting dates showed significantly higher grain yield due to 17.7 plants/m(2) over 9.2 plants/m(2) with no variation over higher plant densities. Among the yield components, number of pods per plant was singnificantly reduced with the increase in plant populations.
