A field experiment was carried out during Kharif season of 2018 to evaluate Effect of nitrogen and sulphur on the performance of blackgram under custard apple (Annona squamosa L.) based agri-horti system. The result indicated that Number of nodules plant-1 decreased drastically from 30 to 50 DAS of crop. The maximum root nodules plant-1 was found at highest nitrogen (40 kg N ha-1) and sulphur level (40 kg S ha-1) followed by, medium and over control at 30 and 50 DAS. The maximum dry matter accumulation plant-1 was observed at 40 kg N and 40 kg S ha-1 whereas; lowest dry matter accumulation was found under control. Increasing levels of N and S from control to 40 kg N ha-1 and 40 kg S ha-1 significantly increased the grain yield, stover yield, biological yield and harvest index of blackgram. The N and S contents in grain and stover of blackgram significantly improved due to 40 kg N ha-1 and 40 kg S ha-1 whereas, minimum was found under control (0 kg N and 0 kg S ha-1). The nutrient uptake in grain and stover of blackgram under custard apple based agri-horti system, increased markedly with increasing levels of nitrogen and sulphur and uptake highest with 40 kg N ha-1 and 40 kg S ha-1 and lowest uptake was found under control. Protein content and protein yield were found statistically superior with 40 kg N ha-1 and 40 kg S ha-1 while minimum was noted in control condition. The maximum gross returns (Rs 55,468 ha-1), net returns (Rs 26,472 ha-1) and benefit: cost ratio (1.94) were obtained with 40 kg N ha-1, although, maximum gross returns (Rs 54887 ha-1), net returns (Rs 24371 ha-1) and benefit: cost ratio (1.83) was maintained by 40 kg S ha-1 and minimum net returns (Rs 17719 ha-1) and benefit: cost ratio (1.38) in control condition.
