Abstract:

An experiment was conducted to study the effect of water soluble on dwarf coconut at Coconut Research Station, Aliyarnagar. Application of 25, 50, 75, 100 and 125% of recommended NPK through drip irrigation system was compared with the soil application of recommended NPK as well as control with no fertilizer application. Application of 125% NPK through drip irrigation resulted in significantly higher Annual leaf production, Number of functional leaves, number of inflorescence and tender nut yield per palm compared to the control and the other fertigation treatments, except 100% NPK through drip irrigation. Higher nutrient availability in split application of fertilizer through fertigation favours increased nutrient uptake resulting in higher nutrient content in coconut leaves. With respect to economics, gross return (Rs. 302400/ha) and net return (Rs.153400/ha) were significantly higher with the application of drip fertigation of 125 per cent RDF through WSF and it found to be on par with drip fertigation of 100 per cent RDF through WSF. The drip fertigation levels 75% of RDF through WSF were found to be on par with 100 % RDF through conventional fertilizers application method i.e through soil application. The study indicated the possibility of saving 25% of the recommended fertilizers by adopting fertigation which ensures higher productivity in coconut than soil application.
