Effect of integrated nitrogen management on micronutrient content in rice
Author(s): W Herojit Meetei, RK Kumarjit Singh, N Surbala Devi and T Sanahanbi Devi
Abstract: A field experiment was conducted for two consecutive years to study the effect of integrated nitrogen management on micro nutrient content in rice var. CAU-R1 (Tamphaphou) during the kharif seasons of 2015 and 2016. Urea, Vermicompost and Azolla were applied as nitrogen sources including one untreated control. Results revealed that application of integrated nitrogen management improved the Fe, Mn, Zn and Cu content of rice in both the years of study as well as pooled data. A declining trend of Fe, Mn, Zn and Cu content in rice with crop age was recorded which might be because of dilution effect, caused by higher dry matter production, low nutrient status of soil and fixation of applied nutrient. Statistically higher micronutrient concentration in rice was observed in soil treated with 75% RDN using Urea + 25% RDN using Vermicompost which is at par with 50% RDN using Urea + 50% RDN using Vermicompost and 100 % RDN using chemical fertilizer Urea + 100 % RDN using Vermicompost + 100 % using Azolla. This might be due to release of nutrients from organic sources thereby increasing soil availability along with inorganic source during the rice growing stage.
