INTERACTION EFFECT OF SULPFUR AND BORON ON THE GROWTH, YIELD, CHEMICAL COMPOSITION AND OIL CONTENT OF MUSTARD (SAU SARISHA-1)

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka during the period from November 2007 to March 2008 to study the effect of sulphur and boron alone and combined on the growth, yield, chemical composition and oil content of SAT) Sarisha -1 (Brassica campeslrtc L.). The experiment included four levels of sulphur viz.. 0, 15,25 and 35 kg S ha" and four levels of boron viz., 0, I. 2 and 4 kg B ha". The experiment was laid out in a Randomized Complete Block Design with three replications. Sulphur showed significant effect on yield and yield attributes of mustard except 1000-seed weight. Application of sulphur @ 25 kg ha 1 produced the highest seed yield, plant height, siliqua plant", siliqua length, seeds siliqua '. 1000-seed weight, stover yield. In all the cases lower response was found from the control treatment. Boron fertilizer also had significant effect on yield and yield attributes of rapeseed except 1000-seed weight. Application of boron @ 2 kg ha' gave the highest seed yield, plant height, pods plant", seeds pod S ', 1000-seed weight, stover yield but in all cases the lower response was found from the control treatment. Sulphur @ 25 kg ha' was found statistically superior to all other treatments. Sulphur in combination with boron showed significant effect on yield and yield attributes of mustard. Sulphur @ 25 kg and boron @ 2 kg hi' resulted the highest seed yield, plant height, stover yield, protein content, oil content and total uptake of S and B by mustard. On the other hand in all the cases lower response was found from the control treatment. The addition of S and B not only increased the yield but also protect the soil from total exhaustion of nutrients.
