Nutrient uptake and yield of clusterbean (Cyamopsis tetragonoloba) as influenced by nitrogen, phosphorus and seed rate
Year: 2001
Type: article
Abstract: A field experiment was conducted at Lakhaoti to study the effect of nitrogen, phosphorus and seed rate on yield and uptake of nutrients in clusterbean [Cyamopsis tetragonoloba (L.) Taubert] on a sandy-loam soil. The soil was low in organic carbon and available N and high in available P and K with pH 7.8. The crop seeded @ 30 kglha gave the highest yield. Application of 20 kg N/ha + Rhizobium inoculation resulted in higher yield over their individual application and control, except Rhizobium alone in 1988. A dose of 60 kg P,O,/ha gave markedly higher seed yield over lower rates of P in both the seasons. Crop seeded using 10 kg seedha recorded noticeably higher gum and protein contents in seed than 30 kgha, but remained at par with 20 kg seedha in both the seasons. Tha highest values of these were noted with 60 kg P,O,/ha and 20 kg N/ha + Rhizobium inoculation. The N and P uptake were highest when crop was seeded with 30 kg seed1 ha, 60 kg P,O,/ha and 20 kg Nha + Rhizobium inoculation.
