ताजे खजूर फल गुच्छों के अधिक उत्पादन हेतु, तेल खजूर (आयल पॉम) में सर्वोत्तम उर्वरक प्रबंधन विधियॉं। Oil palm (Elaeis guineensis Jacq.) is the highest edible oil yielding perennial crop producing two types of oil i.e. crude palm oil and palm kernel oil which are used for domestic and industrial purposes. It produces about 4 to 6 tonnes of crude palm oil and 0.4 to 0.6 tonnes of palm kernel oil per hectare per year during its productive life span from 4th to 30th years. Oil Palm is a heavy feeder and it requires a balanced and adequate supply of macro and micro-nutrients for growth and yield. Fertilizer requirement of Palm Recommended nutrient for oil palm grown under rainfed condition is given in Table 1. It is advised to apply 400-200-400-125 g of N-P2O5-K20-MgSO4 per palm per year during the first year of plantation, 800-400-800-250 g of N-P2O5-K20-MgSO4 per palm per year during second year of plantation and 1200-600-1200-550 g of N-P2O5-K2O-MgSO4 per palm per year during third year onwards. Fertilizer requirements as per the availability of different fertilizers available in the market are given in Table 2. Research on oil palm nutrition conducted at different agro-climatic locations namely Gangavathi (Karnataka), Mulde (Maharashtra), Vijayarai (Andhra Pradesh) and Aduthurai (Tamil Nadu) revealed that the dose...
