Abstract: The present investigation entitled Effect of time of sowing on growth, yield attributes, yield of chickpea. was conducted during rabi season 2013-14 at Research Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh).Studies were carried out on different phenological stages right from sowing to harvesting under irrigated and unirrigated conditions in the three dates of sowing. Based on the duration of different phenological stages the average maximum and minimum temperatures at different growth stages in the different dates of sowing were workout. For comparative analysis Stevenson screen was installed in the crop field and the average maximum and minimum temperatures at different growth stages were also workout using the field data. The number of seed /m2 difference between D1 and D2 under irrigated condition is very highly significance. The difference between D1 unirrigated and D2 unirrigated is not significant. In other treatments the difference is highly significant. Thus the sowing data under unirrigated conditions could be extended till 20th November under Raipur conditions. The grain yield (gm/m2) difference between D1 irrigated and D2 irrigated is highly significant but the difference between D1 unirrigated and D2 unirrigated is not significance. In D1 unirrigated and D3 unirrigated and D2 unirrigated and D3 unirrigated conditions the difference in yield is highly significant. This indicates that under unirrigated condition sowing should not be done after 30th November. Among irrigated conditions the difference between D2 irrigated and D3 irrigated is also highly significant. Difference between D1 and D2 unirrigated condition and between D2 and D3 irrigated condition are not significant. In the other treatments it is significant. This is the reason that the grain yield under these two treatments is not significant. However, D2 and D3 under irrigated condition the grain yield is highly significant but the test weight is not significant. The highest dry matter accumulation was observed at maturity in D1 irrigated (777.2 gm/m2) treatment followed by D1 unirrigated, D2 irrigated and unirrigated. Lowest dry matter accumulation was observed in D3 under unirrigated (248.2 gm/m2). Dry matter production reached almost plateau during maturity of the crop.
