Effect of Different Levels of Nitrogen, Phosphorus and Sulfur on Yield Attributes of Mustard (Brassica juncea L.) Var Varuna at Sandy Loam Soil of Allahabad (UP)

摘要

The experiment was conducted during rahi season of 2013-14. It was observed that the best yield attributes characters was in treatment T_8- @ 120 kg N/ha + 60 kg P/ha -t- 40 kg S/ha in respect to different days intervals i.e. 30,60 and 90 days after sowing (DAS). Plant height was 30.27 cm, 115.53 cm and 160.47 cm, no. of leaves plant' were 16.73,47.33 and 61.53 and no. of branches planr‘ were 5.73,11.47 and 14.07 found to be non-significant at 30 DAS but, significant at 60 DAS and 90 DAS. Highest seed yield (q ha ') and straw yield (q ha~(-1)) WAS 25.33 and 59.33 in T_8 Was found to be significant and highest C : B ratio (1:2.47) was recorded in same treatment T_8,. Adequate plant nutrient supply holds the key for improving the food seed productionand sustaining soil fertility and food security.
