Abstract
ABSTRACT A field experiment was conducted for five years to study the optimal frequency of zinc fertilizer application on zinc deficient Typic Haplaquent in the rice-wheat cropping system. The treatments were soil and foliar application of zinc sulfate at different doses. The results indicate that the pooled yield of rice (32.5 q/ha) was higher than that of wheat grain (15.8 q/ha). The frequency of zinc application, based on ten cropping systems, indicates that the use of 25 kg zinc sulfate/hectare as soil application after a two crop interval was found to be optimal. The rate of increase in yields of rice and wheat was 52.4 and 21.0 kg per kg of zinc sulfate, respectively, and the percent increase in yield of rice was 46.6 and in wheat 38.1. The rice and wheat yield in the cropping system was significantly correlated with zinc removal.
