Effect of Chemical Fertilizers in Combination with Manure on the Physico-chemical Characters of Loquat at Lower Altitude of Murree Hills

Muhammad Akram Nasir, Shafqat Ali Syed, Muhammad Afzal, Shakeel Ahmed and Attiq Akhter


During 1997, maximum weight of the fruit (16.46 g), weight of flesh (14.46 g), seed size in length and diameter (1.81x1.30 cm) and least acidity (0.65 %) was observed in the fruit obtained from the trees which were applied with nitrogen in combination with phosphorus and potash. The trees where no fertilizer was applied, produced the smallest fruit of low quality. The use of potash has significantly reduced the acidity of pulp. But the fertilizer could not affect the T.S.S. contents. Whereas, during the year 1998, the fertilizers significantly increased the T.S.S. contents against untreated plants. Hence, 1 kg of nitrogen in combination with 0.75 Kg phosphorus and 0.50 Kg potassium alongwith 40 Kg of F.Y.M. per tree is recommended for full grown loquat plants.
