ROLE OF PHOSPHORUS AND SULPHUR ON THE GROWTh, CHEMICAL COMPOSITION, YIELD AND OIL CONTENT OF MUSTARD (SAU SHARISHA-1)

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka 1207 during November 2010 to March 2011 to study the role of phosphorus and sulphur on the growth, yield and oil content of mustard (SAU Sharisha-1). The experimental soil was clay loam in texture having pH of 5.8. The experiment included four levels of phosphorus viz., 0, 20. 40 and 60kg P ha4 and four levels of sulphur viz., 0, 15, 30 and 50 kg S hi'. The experiment was laid out in a Randomized Complete Block Design with three replications. Phosphorus showed significant effect on yield and yield attributes of mustard. Application of phosphorus 4), 60 kg hi' produced the highest seed yield, plant height. number of primary branches plant", number of siliqua. plant'1 . 1000-seed weight. Sulphur fertilizer also had significant effect on yield and yield attributes of mustard. Application of sulphur @ 15 kg ha4 produced the highest number of primary branches plant 4, number of siliqua plant" but in all the eases relatively the lower response was found from the control treatment. Phosphorus in combination with sulphur showed significant effect on yield and yield attributes of mustard. Plant height, no. of siliqua plant". siliqua length, no. of seed siliqua ', weight of thousand seed, seed yield was found highest in the treatment combination PS 50,

P40S15,

PS30, P0550 , PS0 , PS,5 respectively. The oil and protein content was found highest in PS30 and P20S30. The addition of P and S not only increased the yield but also protect the soil from total exhaustion of nutrients.
