Evaluation of oat accessions for different agronomic traits under agro-climatic conditions of narc Islamabad

Abstract

Oat is one of the most commonly planted forages and a significant component of crop rotation in a farming system. Keeping in view the importance of oat crop, seven oat accessions were evaluated at National Agriculture Research Center, Islamabad during Rabi season 2020-21. Randomized complete block design with three replications with row to row distance 30 cm was maintained for sowing the aforementioned oat accessions. Significant variation was observed for all the studied traits except plant height and leaves tiller^-1. Highest mean values were observed for Jasper and Local Saryab for number of tillers plant^-1 whereas Jasper was found to have maximum values for leaf area tiller^-1 and leaf area index as well. Maximum flag leaf area was displayed by accession PP2-LV65 while the highest plant height was achieved by accession Local DIK. Maximum leaves tiller^-1 was exhibited by S. 2000 while Local T.Jam achieved maximum green fodder yield and maximum dry matter yield t/ha. On the basis of high values for green fodder and dry matter yield Local T.Jam can be used for onward use for variety development.
