EFFECT OF PHOSPHORUS AND SULPHUR ON THE YIELD AND YIELD CONTRIBUTING CHARACTERS OF SAU SARISHA I (Brassica campestris L.)

Abstract

An experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural University, l)haka. during the period from November 2006 to March 2007 to study the cllect of phosphorus and sulphur singly and also combined on the yield and yield contributing characters of SAL) Sarisha I (Brassia, eainpesnt I..). the experiment included four levels of phosphorous viz.. 0. 30.60 and 90 kg Mi kg haS ' as well as four levels of sulphur vii.. 0, tO, 20 and 30 kg S ha* The experiment was laid out in a Randomized Complete Block l)csign with three replications. Phosphorous showed significant ellect on yield and yield attributes of rapeseed except the number othranches plant'. Application of phosphorus 41 60 kg ha' produced the highest seed yield, plant height. siliqua plant'. siliqua length, seeds siliqua- '. 1000-seed weight. stover yield. biological yield and harvest index. In all the cases lower response was found from the control treatment. Sulphur fertilizer also had significant effect on yield and yield attributes of rapeseed except branches plant' and siliqua length. Application of sulphur 20 kg ha' gave the highest seed yield, plant height, pods plant'. seeds pod'. 1000seed weight. stover yield, biological yield and harvest index. But in all cases the lower response was found from the control treatment. Sulphur (iS

20 kg haS ' was found statistically superior to all other treatments. Phosphorus in combination with sulphur showed significant effect on yield and yield attributes of rapeseed except branches plant". siliqtia length. seeds and 1000-seed weight. Phosphorus @ 60 kg and sulphur &1 20 kg ha" resulted the highest seed yield, plant height, stover yield, biological yield and harvest index. But in all the cases lower response was found from the control treatment.
