Effect of Sources and Levels of Sulphur on Quality, Nutrient Content and Uptake of Summer Cowpea (Vigna unguiculata L. Walp.) under South Gujarat Condition in India

Abstract

A field experiment was conducted during 2021 to study the effect of sources and levels of sulphur on summer cowpea (vigna unguiculata L. walp.) under south Gujarat condition. The results revealed that application of sulphur with gypsum source showed significantly higher seed yield (1392 kg ha-1), stover yield (2502 kg ha-1), crude protein yield (295.18 kg ha-1), nutrients content and uptake (N, P, K and S) by seed and stover and maximum net realization of Rs. 56100.38 ha-1 with BCR of 1.74. The application of 30 kg S ha-1 gave significantly higher crude protein yield (302.03 kg ha-1), seed yield (1393 kg ha-1), stover yield (2508 kg ha-1), nutrients content and uptake by seed and stover and maximum net realization of Rs. 55861.08 ha-1 with maximum BCR 1.71.

Effect of Mineral Fertilizer on Yield, Quality and Nutrient Uptake of Black Sesame [Sesamum radiatum (L.)]

“…Sesame is grown in areas with annual rainfall of 625-1100 mm and temperature of >27 0 C. The crop is tolerant to drought, but not to water logging and excessive rainfall. Sesame is well adapted to a wide range of soils, but requires deep, well-drained, fertile sandy loams" [2].…”

“…Lower productivity is due to use of sub-optimal rate of fertilizer, poor management and cultivation of sesame in marginal and submarginal lands, where deficiency of macronutrients such as nitrogen, phosphorus, potassium and micronutrients is predominant. Balanced fertilization with N, P, K and S is proved beneficial in all the oilseed crops to minimize the unfavourable exploitation of soil fertility and plant nutrient, thus maintain the soil health and plant nutrient at optimum level" [2].…”
