Effect of weather parameter on growth and yield of wheat under different growing environment in bastar plateau zone

The IGKV funded research work was carried out during Rabi 2016 at Instructional cum Research Farm of Shaheed Gundadhoor College and Agricultural Research Station, Kumhrawand, Jagdalpur (C.G.). It comes under bastar plateau of Chhattisgarh which comprises of large plateau having elevation of 553 m above mean sea level and lies between 17°46’ N and 20°34’ N latitudes and 80°15’ and 82°15’ E longitudes. The treatments consisted of three different date of sowing viz., D1- 1st December, D2- 10th December and D3- 20th December 2016 and three wheat varieties viz., V1- Ratan, V2- GW273 and V3- GW366, in factorial randomized block design with three replications.These results lead to conclusion that wheat optimum sowing date for bastar region is first fortnight of December. The date of sowing treatment D1-1st December registered 4250 kgha-1, followed by D2-10th December 4070 kg ha-1 of grain yield. The verities did not influenced yield statistically.
