Seasonal Influence on Seed Yield of Jute ( Corchorus capsularis L.) under Krishna Agro-Climatic Conditions of Andhra Pradesh

A field experiment was conducted at Regional Agricu ltural Research Station, Lam farm, Guntur-34, to study the Seasonal influence on seed yield of jute under rabi sowings in Krishna agro-climatic zone of Andhra Pradesh during rabi 2010-11 and 2011-12. The treatments consisted of combination of two factors viz., four sowing windows (2 nd FN of September, 1 st of FN of October, 2 nd FN of October and 1 st of FN of November) and two varieties (JRO-524 and J RO-8324). The rainfall of 457.4 mm with 18 rainy days was received by crop sown on 2 nd FN of September and the lowest (247.2 mm in 8 rain y days) was received by the crop sown on 1 st FN of October. Due to variation in sowing dates, p lant height, number of branches, number of pods/plant, pod length and seed yield were affected greatly. Correlation coefficie nt between growth, yield and its components and agrome teorological parameter were calculated and parameters showing statistically significant correl ation. Rainfall, rainy days, mean minimum temperature, mean RH2 had shown significantly negat ive correlation while mean maximum temperature, mean sun shine hours, mean RH2, wind speed and pan evaporation had shown positive correlation on yield and yield parameters. Both JRO-524 and JRO-83 24 recorded maximum seed yield in respect of the crop sown on 1 st FN of November followed by 2 FN of October.
