A study was conducted to access the micronutrient status of Zn, Cu, and Mn in banana growing tracts of Thoothukudi district of Tamilnadu. A total of 238 surface soil samples were collected from farmer’s field and analyzed for DTPA-extractable micronutrient status and soil properties. Content of micronutrient was in order of Fe> Mn > Cu> Zn. The DTPA- Zn, Cu, Fe and Mn in soils varied from 0.22 to 2.89, 0.32 to 5.73, 3.00 to 71.18 and 2.87 to 33.56 mg kg-1. © 2014, Journal of Chemical and Pharmaceutical Research. All rights reserved.

The present study was undertaken with the objective to determine the degree of association between yield and its component characters and their direct, indirect effects on grain yield in rice (Oryza sativa L.). A line x tester analysis was carried out with 8 lines and 5 testers at the Agricultural College and Research Institute, Madurai to study the genotypic correlations and path coefficient analysis in Rice. Ten characters were investigated viz., Days to 50 per cent flowering, plant height, panicle length, number of productive tillers per plant, number of filled grains per panicle, hundred grain weight, kernel length, kernel breadth, kernel length breadth ratio and single plant yield. The results showed that an intensive selection in the positive side for plant height, number of productive tillers per plant, filled grain per panicle and hundred grain weight will improve the single plant yield since these traits expressed significantly positive correlation with grain yield and among themselves.
