Effect of Sources and Levels of Sulphur on Yield and Qualityof Summer Groundnut

摘要

The probable reasons for declining yields of groundnut are; unscheduled sowing dates, inadequate and imbalanced nutrition and moisture stress at critical stages. Among these factors, mineral nutrition to groundnut plays an important role in productionof groundnut. Dimree et al. (1993) indicated that application of sulphur increased the yield attributes and yield of groundnut. Agasimani et al. (1993) observed significant increase in the yield and oil content of groundnut due to application of sulphuron medium black soil. Singh (2000) reported that about 45 districts of the country showed more than 40 per cent sulphur deficiency. Therefore, sulphur is now considered as fourth major plant nutrient next to nitrogen, phosphorus and potassium. For production of one tone seed on average 10 kg sulphur is required for oil seed crop. Considering the above facts the present study was under taken to study the effect of levels and sources of sulphur on yield and quality.
