Effect of various combinations of organic and inorganic sources on yield and quality of lablab bean in Konkan region of Maharashtra

Abstract

A field trial was conducted during rabi seasons of 2015-16 and 2016-17 with an objectives to assess the effect of different INM treatments on yield and quality of lablab bean (cv. Konkan Wal-2). The treatments comprised of three sources of N at RDF (urea, FYM and urea + FYM), three levels of P (0, 75 and 100 per cent P of RDF) along with PSB and VAM inoculations (no inoculation and inoculation) and a control making in all nineteen (18+1) treatment combinations. Each treatment was replicated thrice in a randomized block design. Application of 100 per cent N through an equal integration of urea and FYM when super imposed with 75 per cent P of RDF along with PSB and VAM inoculations resulted in maximum seed yield and protein content of lablab bean during both the years of investigation. It was closely followed by the treatment T19 receiving similar doses of fertilizers/manure as in case of T18 with extra addition of 25 per cent P of RDF without PSB inoculation. Thus, a saving of 25 per cent P of RDF for lablab bean crop is possible under INM on Alfisols of Maharashtra.
