Yield of Mustard as Influenced by Date of Sowing and Varieties in Western Rajasthan, India

An experiment was conducted at agricultural research station, SKRAU, Bikaner during rabi season of 2017-18 to evaluate yield of mustard as influenced by date of sowing and varieties in western Rajasthan. The treatment consisted of three dates of sowings viz., 10th October, 25th October and 9th November were kept in main plot and five varieties viz. RH-119, NRCHB-101, RGN-48, RH-749 and Laxmi was kept as sub plot replicated thrice in split plot design. Crop sown on 25th October recorded significantly higher seed yield as compared to 9th November sowing. In case of stover yield of mustard maximum was recorded under 25th October as compared to 10th October and 9th November. Days taken for emergence were no significant difference in varieties. RH-749 taken maximum days for 50 per cent flowering as compared to all varieties and for Siliqua appearance maximum days also taken by RH-749 as compared to NRCHB-101 and it statistically at par with RH-119, RGN-48 and Laxmi. RH-119 days to maturity and no. of branches/plant were minimum as compared to all varieties and these were remained statistically at par with each other. Maximum number of siliqua /plants was recorded under RGN-48 which was superior over rest of varieties and statistically at par with NRCHB-101. Highest grain/siliqua was recorded under NRCHB-101 over RH-119, RGN-48 and RH-749.
