Effect of the Phosphorus and Sulphur Levels on Growth and Yield of Mustard (Brassica juncea L.) Crop under Rainfed Condition

Abstract

Background: Phosphorus has been pointed out as one of most important in oilseed crop wich is responsible for vegetative growth,reproduction and consequently yield of mustard. Sulphur element is important for crop growth and development especially in oilseed. At present, 42% of Indian soil have been found to the sulphur deficient, sulphur is essential for synthesis of oil percentage, protein, vitamins, in oilseed crops. Methods: The field investigation was carried out at the Rajaula Research Farm, Faculty of Agricultural Science ,Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalay, Chitrakoot- Satna (M.P.) during Ravi season 2019-20. The treatment comprised three levels of phosphorus and three levels of sulphur along with absolute control. Result: The result revealed that application of 30kg phosphorus/ha significantly increase the plant height , plant leaves, primary branches, secondary branches and yield indices vis number of siliqua/plant, number of seed/siliqua, 1000 seed weigh and seed yield than 20kg phosphrus/ha and 0kg phosphorus/ha . Sulphur levels also hed significantly influereced on these growth and yield indices and reconded higher values 20kg sulphur/ha found at per 10kg sulphur/ha and significantly higher over 0kh sulphur/ha. The finding that application of 30kg phosphorus with 20kg sulphur/ha proved the most optimum and beneficial fertility management for the Pusa Mahak veriety mustard for the Bundelkhand/ chitrakoot region of M.P.
