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. |
