Agro-Morphological Characterization of Oat Genotypes Under Climatic Conditions of Tandojam

Abstract

The current study was conducted at Agronomy Section,Agriculture Research Institute, Tandojam during the growing season of 2019-20,toassess new oat genotypes for their growth performance under the environmental conditions of Tandojam. For this study, a total of eleven new oat genotypes along with one check genotypewere grown for their evaluation. A total of seven characters consistingcrop stand (m-2), plant height (cm), leaves plant-1, number of tillers plant-1, leaf area (cm-2), green fodderand dry mater yield (t ha-1)were investigated. The mean squares values for the investigated traits of all the genotypes were found significantly different(P≤0.05) among the genotypes, which showsthat these genotypes possess valuable genetic combinations for further improvements. Under the agro-climatic conditions of Tandojam, the maximum crop stand (96.66 m-2), greater green fodder (86.00 t ha-1) and alsomaximum dry matter yield (43.00 t ha-1) was produced by Entry-D; the Entry-H produced the tallest plants (96.66 cm) and maximum number of leaves plant-1(68.00). WhereasEntry-F produced maximum number of tillers plant-1 (17.66). Hence, these oat genotypes may be preferred for commercial cultivation in the tested climatic conditions. Regarding correlation results, the traits crop stand (r=0.93**), tillers plant-1 (r=0.39*) and leaf area (r=0.38*) showed significant and positive associations with green fodder yield, hence these characters may be given priority in high yielding oat cultivar development
