Abstract:
The present experiment was conducted to determine “Studies on the effect off foliar application of nitrogen and phosphorus on growth, flowering and fruiting of guava (Psidium guajava L.) in three year old plant cv. Allahabad Safeda” under Allahabad agro-climatic conditions in the Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Sciences, Allahabad, (U.P.) during the year 2016-2017. The field experiment was conducted in Randomized Block Design with 10 Treatments each treatment replicated thrice, different concentrations of Nitrogen through urea (0.2%, 0.4% and 0.6%) and Phosphorus through SSP (0.2%, 0.4% and 0.6%] were used. The result reveals that Treatment T₉ [(Nitrogen through urea (0.6%) + Phosphorus through SSP (0.6%)] was effective in improving pre and post-harvest parameters of guava. Treatments influenced significantly Plant height (cm), Number of branches per plant, No of leaves per plant, No. of cluster per plant, No. of Fruit set per plant, Fruit set percent, Yield per plant and yield q/ha and Post-harvest attributes like, TSS, Ascorbic acid%, Total sugar%, Pectin (%), Acidity (%) and P^H was also found maximum in treatment T₉ and minimum was recorded in treatment T₀-control.
