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 /m
2 difference between D
1 and D
2 under irrigated condition is very highly significance. The difference between D
1 unirrigated and D
2 unirrigated is not significant. In other treatments the difference is highly significant. Thus the sowing data under unirrigated conditions could be extended till 20
th November under Raipur conditions. The grain yield (gm/m
2) difference between D
1 irrigated and D
2 irrigated is highly significant but the difference between D
1 unirrigated and D
2 unirrigated is not significance. In D
1 unirrigated and D
3 unirrigated and D
2 unirrigated and D
3 unirrigated conditions the difference in yield is highly significant. This indicates that under unirrigated condition sowing should not be done after 30
th November. Among irrigated conditions the difference between D
2 irrigated and D
3 irrigated is also highly significant. Difference between D
1 and D
2 unirrigated condition and between D
2 and D
3 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, D
2 and D
3 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 D
1 irrigated (777.2 gm/m
2) treatment followed by D
1 unirrigated, D
2 irrigated and unirrigated. Lowest dry matter accumulation was observed in D
3 under unirrigated (248.2 gm/m
2). Dry matter production reached almost plateau during maturity of the crop.
