Description Studies on ?Effect of N, P & K on growth, yield and quality of guava (Psidium guajava L.) cultivars under meadow system of planting? were carried out during the period from July, 2013 to January, 2014 at Fruit Research Station (FRS), Sangareddy, Medak district, Dr.YSRHU, A.P. with an objective of studying the effect of varieties and fertilizer levels on growth, yield and fruit quality of guava cultivars under meadow system planting. Studies were conducted on the effect of two varieties i.e. Allahabad Safeda and Lalit and also effect of different fertilizer levels i.e. 65:30:30 g, 100:45:45 g, 135:60:60 g, 170:75:75 g and 205:90:90 g per plant on growth, yield and fruit quality of guava (Psidium guajava L.) cultivars with 10 treatments replicated four times in RBD with factorial concept. Among the two varieties studied, Lalit responded well to different fertilizer doses when compared to Allahabad Safeda. Lalit recorded maximum plant height, stem girth, plant spread at east-west and north-south direction, total number of flowers per shoot, number of fruits per plant, average fruit weight, fruit volume, total soluble solids and ascorbic acid. Allahabad Safeda recorded maximum fruit set and minimum number of days taken for harvesting from flowering in meadow system of planting. Among the different fertilizer levels (65:30:30, 100:45:45, 135:60:60, 170:70:70 and 205:90:90 g per plant ) studied, increasing the fertilizer level from
65:30:30 to135:60:60 resulted in increase of the number of fruits per plant, maximum average fruit weight, fruit girth, fruit volume, fruit yield and maximum storage life. But, further increase in fertilizer doses decreased the above characters in meadow system of planting of guava. Among the interactions, Lalit with 135:60:60 g NPK per plant recorded maximum stem girth at 90 days and at harvest. Allahabad Safeda with 135:60:60 g of fertilizer level showed minimum number of days taken for flowering from first split of fertilizer application and minimum number of days taken for harvesting from flowering. 205:90:90 g NPK per plant recorded maximum total soluble solids, ascorbic acid content and total sugars but was at par with 170:70:70 g and 135:60:60 g NPK per plant. Application of 135:60:60 g NPK per plant for two years old guava plant in two split doses were found to be optimum in increasing growth, fruit yield and quality of guava cultivars under meadow system of planting in Telangana conditions of Andhra Pradesh.
