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.

A field experiment conducted during summer season 2018 on College Farm, Navsari Agricultural University, Navsari on heavy black soil consisting nine treatments combinations were laid out in Randomized block design with factorial concept with four replications. The results revealed that the highest yield and net return of summer pearl millet was obtained with row spacing 45 × 15 cm or 60 × 15 cm along with hybrid GHB – 732 or GHB –558. Sowing of pearl millet at 45 × 15 cm row spacing showed significantly higher protein yield (508.85 kg/ha), grain yield (4775 kg/ha), straw yield (7828 kg/ha), nutrients uptake by grain and straw and maximum net realization of Rs.81295/ha with BCR of 3.07.  The hybrid GHB-732 gave significantly higher protein yield (498.75 kg/ha), grain yield (4579 kg/ha), straw yield (7536 kg/ha), nutrients (N and K) uptake and total uptake by grain and straw and maximum net realization of Rs.77014/ha with highest BCR 2.91.
