TL;DR: The correlation studies of 24 F1 crosses showed that, grain yield per plant exhibited highly significant positive association with plant height, number of productive tillers per plant, panicle length, grains per panicle, and harvest index while days to 50 per cent flowering registered non-significant negative association with grain yield.

Abstract: : The experiment was conducted out at the Indian Institute of Rice Research, Rajendranagar, Hyderabad during dry season (Rabi) 2013-2014 and Wet season (Kharif) 2014 crop seasons. The objective was to establish the nature of relation between grain yield and yield components by partitioning the correlation co-efficients between grain yield and its components into direct and indirect effects by using simple correlation and path analysis. A correlation co-efficient and path analysis study was conducted with eleven parents and their 24 F1 crosses for eleven component characters including grain yield. The correlation studies of these crosses showed that, grain yield per plant exhibited highly significant positive association with plant height, number of productive tillers per plant, panicle length, grains per panicle, and harvest index while days to 50 per cent flowering registered non-significant negative association with grain yield

TL;DR: In this article, genetic divergence was studied for grain yield and six other morphological characters in mungbean and the results showed that these characters are governed by additive genetic effect and improvement of these characters would be effective through phenotypic selection.

Assessment of bat guano as source of nutrients for rice production
A. A. Hatibu
- 01 Jan 2018
TL;DR: It was concluded that P release from the three bat guano deposits in soils is gradual and reaches the pick in almost three months after application, and should be applied at least two months before planting to ensure that P will be readily mineralized and available in soil to be taken up by plant.

Correlation and Path Coefficient Analysis for Yield and Yield Related Traits of Upland Rice (Oryza sativa L.) Genotypes in Northwestern, Ethiopia
TL;DR: Assessment of trait association and direct and indirect effects of yield related traits on grain yield of upland rice genotypes revealed strong positive correlation between grain yield and other traits, which helps in identifying traits that could be used for indirect selection for the improvement of grain yield.

TL;DR: High values of heritability and genetic advance were observed for total spikelet per panicle, thousand grain weight and total biomass, and these traits which contribute to the grain yield under alkaline soil condition could be exploited for further breeding programme.
