EFFECT OF ORGANIC AND INORGANIC FERTILIZERS ON QUALITY AND SHELF LIFE OF GUAVA (PSIDIUM GUAJAVA L.) CV. SARDAR

Abstract

The two year data indicates that 25% of N tree^-1 through FYM + 75% of N tree^-1 through inorganic fertilizer (T₁₀) was found to be best as compared to other treatments which significantly increased the physico-chemical attributes of guava in both the years where highest fruit length (8.35 & 8.42  cm), breadth (7.92 & 7.95 cm) and fruit weight (240.85 & 247.62 g) were recorded respectively in trees receiving 25% of N tree^-1 through FYM + 75% of N tree^-1 through inorganic fertilizer whereas, the chemical attributes viz. TSS (12.92 & 12.97 ⁰B), total sugars (8.56 & 8.65 per cent) and the minimum physiological loss in weight (14.29 per cent) after 10 days under ambient conditions during both the years were found to be maximum with the application of Azotobactor + 50% of N tree^-1 through FYM + 50% of N tree^-1 through inorganic fertilizer (T₉) which were at par with the treatment comprising 25% of N tree^-1 through FYM + 75% of N tree^-1 through inorganic fertilizers.
