Evaluation of various herbicide treatments on growth, yield and economics of barley (Hordeum vulagre L.) under the irrigated condition of Jharkhand

Abstract

A field experiment was conducted during Rabi season of 2023-2024 to study the evaluation of various herbicide treatments on growth, yield and economics of barley (Hordeum vulagre L.). The experiment was led out in randomized block design (RBD) and replicated thrice with the variety DWRB137. The treatment consists of (T1)- Halauxifen- methyl (1.21% EC) + Fluroxypyr (38.9% EC), (T2)-Metsulfuron methyl (20% WG) + Surfactant (0.2%), (T3)-Carfentrazone(40% DF), (T4)- Metsulfuron methyl (20% WG) + Carfentrazone (40% DF)+Surfactant (0.2%), (T5)-2, 4-D-Sodium Salt (80% WP), (T6)- 2, 4-D- Sodium Salt (80% WP) + Carfentrazone (40% DF), (T7)-2, 4-D-Ethyl Ester (38% EC), (T8)-2, 4-D- Ethyl Ester (38% EC) + Carfentrazone (40% DF), (T9)- Weedy check, (T10)-Weed free. Application of Halauxifen- methyl (1.21% EC) + Fluroxypyr (38.9% EC) recorded significantly highest plant height at maturity (85.81cm). This combination of herbicide also resulted in the highest yield attributes and yield namely number of ear head/m2 (305/m2), ear head length (7.35 cm), number of grains per ear head (44.33), test weight of grain (38.03 g) and grain yield (3428.74 kg/ha), straw yield (5328.66 Kg/ha) net return (50039 Rs./ha) with highest B:C ratio (2.94) followed by Metsulfuron methyl (20% WG) + Carfentrazone (40% DF) + Surfactant (0.2%).
