ABSTRACT
In order to estimate the effect of organic and inorganic sources of nitrogen the present experiment was conducted on 5 years old Sardar guava trees growing at Instructional- cum Research Farm, Department of Horticulture, College of Agriculture, Latur during 2009-2010. For the investigation different sources of nitrogen viz., urea, vermicompost, neem cake, FYM, poultry manure and green manure in combination were used. The results of experiment revealed that integration of organic manures and inorganic fertilizers was more effective in increasing yield and quality of guava trees than the inorganic fertilizers alone. Among the various combinations 75% of nitrogen through urea along with 25% nitrogen through neem cake (T ) was found the best over most of the treatments in respect of yield parameters like weight of fruit 4 (243.80 g), yield per tree (58.1 kg) and yield per hectare (23.26 tonnes) and physico-chemical properties like fruit length (8.39 cm), pulp: seed ratio (40.41:1), reducing sugars (5.35%) and minimum acidity (0.32%).
Key words :
Guava, neem cake, nitrogen, organic manures, physico-chemical properties, Psidium guajava, vermicompost.
