CONTINUOUS CROPPING OF RICE-INFLUENCE OF TEMPERATURE ON UPTAKE OF N, P. K AND Zn IN RICE

Abstract

                                In a field experiment involving twelve monthly plantings of rice in a calendar year it was observed that the pattern of uptake of NPK and Zn was influenced by temperature prevailing at the growth stages Zinc content at tillering was higher in February planted crop which gave the highest grain yield. The correlation studies of uptake with grain yield pointed out that phosphorous and potash uptake was having positive relationship with available zinc in the soil at the tillering stage of the crop.
