dc.description.abstractThe response to three levels of NPK by young palms of three high yielding types of coconut was studied. The three types of palms tried were natural cross dwarf, tall X dwarf hybrid and pre-potent tall. The fertilizer levels per adult palm per year were no fertilizer, 0.5 kg N + 0.25 kg P2O5 + 0.75 kg K2O and the double of the above level. Application of fertilizers resulted in highly significant increase in all the growth characters studied. The mean percentage increase in height over 'no fertilizer' ranged between 191 and 301 in December, 1967 and between 193 and 283 in December, 1968. Similar trends were observed in respect of girth at collar and number of leaves produced. Difference in response due to the higher level of fertilizer mixture over the lower level was not significant. It would be of interest to observe whether the absence of difference in response between the two levels of nutrients would persist till the flowering stage and would be reflected in the yield of nuts as well. The optimum level of fertilizer mixture was found to be near the higher level, viz.. 1.0 kg N + 0.5 kg P2O5 + 1.5 kg K2O per adult palm per year.en_US
