ABSTRACT:

Occurrence of sulphur deficiency in Nigerian soils is becoming frequent and extensive due to intensive cultivation and shift from low analysis fertilizers to high analysis fertilizers, which do not contain sulphur. Information is required on the parameters for evaluating sulphur status and requirement of crops in the country. Studies were conducted in the laboratory, greenhouse and farmers fields to evaluate the sulphur status and requirement of groundnut in some soils of Benue state. The soils included Abinsi, Ikpayongo, Yandev, Gbatse, Tse-mker and Makurdi. The greenhouse experiment consisted of 4 sulphur treatments (0, 10, 20 and 30 kg S ha-1) applied as K SO . The crop was grown in the pots and harvested 2 4after 12 weeks. The result of the study indicated that the soils were very low in their total sulphur content and ranged from 60.0 mg Kg-1 at Yandev, Gbatse and Tse-mker to 93.0 mg Kg-1 at lkpayongo. Correlationstudy showed that the sulphur content was significantly related to soil organic matter and clay content of soils. Groundnut dry matter and pod yield were significantly related to the rate of sulphur application. Response to sulphur application was observed up to 30 kg S ha-1. It was concluded that the probability of obtaining groundnut response to sulphur application will be high.
