EFFECT OF SULPHUR ON YIELDS AND S UPTAKE BY ONION AND GARLIC GROWN IN ACID ALFISOL OF RANCHI

摘要

Field experiments were carried out for three consecutive years ((2001 to 2004) at farmer's field of Ranchi district to study the response of graded levels of sulphur on bulb yields and S uptake by onion and garlic crops applied through sulfer' 95 andgypsum. An increase of 37.8 q ha1 in bulb yield of onion and 18.8 q ha1 bulb yield of garlic were obtained with S application up to 40 kg ha1 over the recommended dose of fertilizers (NPK). Sulfer' 95 was identified superior over gypsum to meet the S requirement of onion and garlic in S deficient soils of Ranchi. S use efficiency was found to be higher by these two crops with sulfer' 95 than that of gypsum application.
