Effect of fertigation on growth and yield of mango cv. Alphonso under Konkan agro climatic condition

Abstract

A fertigation experiment was conducted to assess the spatio-temporal variation in soil water content, productivity, fruit quality and nutrient distribution in drip irrigated mango cv Alphonso. For this purpose, full bearing and mature (30 years old) trees were subjected to fertigation application of N, P and K in different proportion at different time i.e. after harvest, during fruit set and at marble stage of fruit. Results revealed that the yield parameters namely number of fruits and yield kg/tree was found significant. Significantly the highest number of fruits/tree (140.89) and yield/tree (38.16) were recorded in the treatment T3 (N-25%, P-50%, K-15%, through drip at after harvesting, N-20%, P-25%, K-15% during fruit set and N-30%, K-45% at marble size of fruits) and was superior over all the treatments under study. The fruit quality parameters i.e. fruit weight (g), Yield (t/ha), TSS (OB) and acidity (%) were found non significant.
