摘要:To investigate the effect of different levels of potassium fertilizer with and without use of Farmyard Manure (FYM) on growth, yield and nutrition of tomato a study was carried out in year 2011 in pots. FYM was kept as main plots with five treatments of potassium (0, 60, 90, 120 and 160 kg K2O/ha) replicated four time. The results indicated that application of FYM and various K levels had significant effect on the growth, yield and nutrient content of tomatoes. The highest yield of tomatoes was (39.05 t/ha) observed in the pots receiving FYM and 41.97 t/ha was found in the treatment receiving K @ 120 kg/ha. The growth parameters including number of flowers per plant, number of fruits per plant and fruit diameter were also found significantly different by the application of FYM and K fertilizer. The mineral nutrition of tomato showed significant effect of FYM and K levels on plant P and K. FYM and K levels also significantly improved soil K content. It may be concluded that the Potassium applied @ 120 kg/ha along with the FYM was effective in improving the tomatoes attributes as well soil K content.
