Integrated nutrient management for
The establishment and growth of the tree crops planted in wastelands are not satisfactory. Nutrient supply is one of the major factors, which decides the establishment and growth of trees planted in wastelands.
In wastelands (sandy loam clay soil) under rainfed conditions, nutrient treatments were imposed twice a year i.e., during the onset and cessation of monsoon. Lower plant height in native soil without any fertilizer application. When Farm Yard Manure and Di-ammonium phosphate are applied in combination with bio-fertilizers the response was better.
Combined application of farm yard manure 25kg + DAP 50kg + Azospirillum 50g + Phosphobacteria 500g/tree recorded the maximum height after 3-1/2 years of planting.
Maximum girth was recorded in combined application of organic, inorganic and bio-fertilizer applied trees. Hence there should be integrated nutrient management practice for better growth of Neem trees planted in wastelands under rainfed condition.
