Abstract: The effect of combine application of inorganic fertilizers and FYM on nutrient content i.e., Nitrogen, phosphorous and potassium as well as quality parameters such as reducing sugars, non-reducing sugars, starch, crude fiber, protein, moisture content and shelf life of yam bean (Pachyrhizus erosus L.) tuber was investigated in Alfisols of Konkan region. The field experiment was conducted during Kharif 2020 at research farm of Central Experiment Station, Wakawali, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Dist. Ratnagiri. The experiment comprised of different levels of nitrogen (80,100,120 kg ha-1), phosphorous (40, 60, 80 kg ha-1), a constant dose of potassium (100 kg ha-1) alone and in combination with different levels of farm yard manure (10, 15, 20 t ha-1), was laid out in thirteen treatment combinations consisting one absolute control which was replicated thrice in randomized block design. The nutrient content of yam bean leaves and yam bean tubers were observed to be highest in treatments receiving higher dose of nitrogen, phosphorus and FYM as compared to sole application of inorganic sources and absolute control. The highest NPK content of tuber recorded was 0.61 percent, 0.24 percent and 0.24 percent, respectively. The various quality parameters were significantly improved due to various treatments receiving combined application of inorganic fertilizers and organic manures over control treatment. The total yam bean tuber yield (23.02 t ha-1) recorded was significantly highest under treatment consisting 120:80:100 N, P2O5, K2O kg ha-1 + 20 t FYM ha-1. The study further concluded that integrated nutrient application significantly improves quality as well as quantity of yam bean in lateritic soils of Konkan region of Maharashtra.
