Response of short-duration pigeonpea (Cajanus cajan) to nitrogen, Rhizobium inoculation and phosphorus

A field experiment was conducted during the rainy season (kharif) of 1994 a nd 1995 to study the response of pigeonpea [Cajanus cajan (L.) Millsp.] to nitrogen, Rhizobium inoculation and phosphorus. Rhizobium inoculation incre ased the dry-matter accumulation, nodules/plant, yield attributes and yield . Nitrogen application up to 40 kg/ha increased the grain and protein yield . Phosphorus @ 40 kg P2O5/ha increased the grain yield significantly over t he control. Rhizobium inoculation was of significant consequence and benefi t to pigeonpea crop under all the levels of nitrogen. The Rhizobium inocula tion with 20 kg N/ha was found superior to 20 kg N/ha alone and was on a pa r with 40 kg N/ha.
