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 agrihorti 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. |
