Effect of irrigation regimes on growth and yield of Barley (Hordeum vulgare L.) varieties

Abstract

A field experiment was conducted during Rabi season of 2019-20 at department of Agronomy, R.B.S. College Bichpuri, Agra. The variable involved in this study were four stages of irrigation (No irrigation-I0 one irrigation at Jointing stages-I1 two irrigations at Jointing & flowering stage-I2, three irrigation at Jointing, flowering and grain filling stages-I3) and two varieties viz. BH-946 (V1) and DWRB-160 (V2) thus, in all 8 treatment combinations were compared in a “split plot design” having stage of irrigation in main plots and varieties in sub-plots with four replications. The soil of experimental field was sandy loam in texture with a pH 7.85. The soil was low in available nitrogen (172.65 kg ha-1), medium in available phosphorus (25.20 kg P2O5 ha-1) and rich in potash (215.1 kg K2O5 ha-1). the field capacity was 16.50 per cent and wilting point was 7.80 per cent, During Rabi season of 2019-20 no rains were received during the crop season. Results showed that I₃ significantly outperformed other treatments across all yield parameters, including the highest biological yield (109.88 q/ha), grain yield (45.79 q/ha), and harvest index (41.69%). All the growth and yield attributes can be obtained appreciable higher with barley variety DWRB-160.
