Response of late sown mustard to different nutrient combinations

The field experiment was conducted at Agronomy Research Farm NDUA&T Faizabad during the rabi season of 2011-12 to assess the “Response of late sown mustard varieties to different nutrient combinations”. The experimental field having the soil texture silty loam pH 7.9 O.C 0.32% EC 0.33% and available N available P available K available S and available Zn were 180.4 kg ha-1 18.4 kg ha-1 290 kg ha-1 7.3 (ppm) and 0.59 (ppm) respectively. Treatments were consisted of five nutrient combinations and three varieties of mustard i.e. Vardan Narendra Rai-1 and Narendra Ageti Rai-4. Application of 120 kg N + 60 kg P2O5 + 40 kg K2O + 40 kg S + 5 kg Zn + 0.2% Boron spray before flowering increased almost all the growth yield attributes and biological seed and Stover yield of mustard significantly over to rest of the nutrient combinations. Significant higher oil content was recorded with 120 kg N + 60 kg P2O5 + 40 kg K2O + 40 kg S + 5 kg Zn + 0.2% Boron spray before flowering over rest of the treatments. Among the different mustard varieties Narendra Rai-1 being at par with Vardan recorded significantly higher growth and yield attributes as well as yield and oil content.
