Rapeseed- Mustard is the second most important oilseed crop in India after soybean and accounts for nearly 20-22% of total oilseeds produced in the country. Mustard seed is grown with a different consumption pattern in the country, Indian mustard is mainly used for extraction of mustard oil while black mustard is mainly used as a spice (Anonymus, 2015). Improved varieties plays a crucial role in raising the seed yield of the crop. Development of HYV’s of mustard has been one of the major concern of the scientists because use of the improved varieties alone accounts for 15-20% increase in productivity. This is probably because of their altered morphology which results into efficient utilization of water, nutrients and radiation. The fertilizers have played a prominent role in increasing the oil seed production, balanced fertilization is the key to achieve higher production and increase nutrient use-efficiency. Use of optimal dose of primary, secondary and micro nutrients International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 2 (2017) pp. 1343-1347 Journal homepage: http://www.ijcmas.com Keywords Mustard, Varieties, Nutrient combinations, Seed yield. Accepted: 22 January 2017 Available Online: 10 February 2017 Article Info A field experiment was conducted at N.D.U.A&T, Faizabad, U.P., to assess the response of mustard varieties (Brassica juncea L.) to different nutrient combinations under late sown condition during winter (rabi) season of 2011-12. Application of 120 kg N+60 kg P 2 O 5 +40 kg K 2 O+40 kg sulphur+5 kg Zn+0.2% Bo spray before flowering (F 5 ) recorded significantly higher plant height (except 30 DAS), primary branching and yield over rest of the treatments but remained at par with 120 kg N+60 kg P 2 O 5 +40 kg K 2 O+40 kg S+5 kg Zn (F 4 ). However, significantly higher oil content was recorded with 120 kg N+ 60 kg P 2 O 5 +40 kg K 2 O+40 kg S+5 kg Zn+0.2% Bo spray before flowering over rest of the treatments but remained at par with 120 kg N+60 kg P 2 O 5 +40 kg K 2 O+ 40 kg S and 120 kg N+60 kg P 2 O 5 +40 kg K 2 O+40 kg S+5 kg Zn. Among the different varieties, Narendra Rai-1 being at par with Vardan recorded significantly higher plant height (except 30 DAS), primary branching as well as yield and oil content over Narendra Ageti Rai- 4.
