Abstract
In 1985-87, short-duration pigeonpeas cv. ICPL 87 were grown on a Vertisol and an Alfisol at ICRISAT Center (peninsular India), an Inceptisol at Gwalior (central India) and an Entisol at Hisar (N. India) in as non-limiting environmental conditions as possible. N fertilizer was applied to the soil at various growth stages to determine when N becomes most limiting. There was a significant response in seed yield to N applied at flowering in the Vertisol but not in the Alfisol, Inceptisol or Entisol. This suggests that biological N2 fixation by the short-duration cultivar was not adequate to meet N requirements of the crop grown in the Vertisol but that it was probably adequate in the other 3 soil types. These results are discussed in relation to the nodulation and acetylene reductase activity of pigeonpeas and also the N mineralization potential of different soils
