TilleringBehaviour and Yield of Different Duration Rice Varieties under different Dates of Sowing under Aerobic Culture

A field experiment was conducted at Agriculture Research Station, Madhira for two consecutive seasons of kharif, 2012 and 2013 on clay soils to study the effect of different sowing dates on tillering behavior, growth and yield of rice varieties under aerobic culture. The results indicated that, the crop sown early i.e on 18 June produced more number of total and effective tillers, grain and straw yields and decreases with every successive 15 days delay in sowing from 7 July to 18 August during both the years. Among the cultivars medium and long duration cultivars viz., JGL 11470 and MTU 1061 took more number of days to reach maximum tillering and produced more number of tillers, grain and straw yields over short and extra short duration cultivars viz., JGL 17004 and MTU 1010. Therefore, under assured irrigation and well distributed rainfall condition early sowing of long and medium duration cultivars would produce more yields under aerobic culture in Central Telangana Zone of Telangana State, India.
