IMPACT OF FERTILITY LEVELS ON BARLEY (HORDEUM VULGARE L.) VARIETIES' GROWTH AND YIELD IN UTTAR PRADESH'S CENTRAL PLAIN ZONE

Abstract

To determine the Impact of Fertility Levels on Barley (Hordeum vulgare L.) Varieties' Growth and Yield in Uttar Pradesh's Central Plain Zone, a field experiment was carried out at the agricultural farm of Rama University, Kanpur, during the rabi seasons of 2023–2024.The treatment included three fertility levels (F1 (N, P2O5& K2O)- 40;20;20, F2 -60;30;30, and F3- 80;40;40) assessed in a split plot design (SPD), and nine combinations of three varieties (V1-Haritma (K-560), V2-Narmada (K-603), and V3-Lakhan (K-226)).Whereas 'Lakhan' (26.43 q/ha) generated lower grain yield, 'Haritma' (29.51 q/ha) and 'Narmada' (29.40 q/ha) were comparable. The highest grain yield (31.22 q/ha) among fertility levels was achieved by N-80, P-40, and K-40, followed by N-60, P-30, and K-30 (29.27 q/ha), and the lowest yield was recorded by N-40, P-20, and K-20 (24.85 q/ha).
