A field experiment was conducted at the Research Farm, Department of Agronomy, College of Agriculture, CCS HAU, Hisar (Haryana), India during Rabi, 2018-19. The experiment was laid out in a split-plot design in three replicates, keeping cutting management (No cut, cut at 56 DAS, cut at 68 DAS) in main plot and varieties (BH 393, BH 946, RD 2552 and RD 2715) in sub-plot. Highest plant height (64.8 cm and 79.6 cm) and green fodder yield (17.40 t/ha and 23.21 t/ha) were recorded with the variety RD 2552 and RD 2715 at 56 DAS and 68 DAS, respectively. Lowest canopy temperature was also recorded with RD 2715 at both the stages. The results also showed that highest grain and straw yield of 5.05 t/ha and 9.30 t/ha, respectively was produced in no cut treatment. Yield attributes viz. Effective tillers/m2, test weight and no. of grains per ear-head were also found maximum in no cut treatment. Among the varieties, RD 2552 recorded with highest grain and straw yield (3.01 t/ha and 5.80 t/ha). Significantly highest effective tillers/m2 of 318.2 was also found with RD 2552. Canopy temperature was significantly lower in the variety RD 2552, however, maximum value of NDVI and SPAD were recorded in RD 2552 and RD 2715. However, highest no. of grains per earhead was recorded with BH 393(49.3). Highest B:C was observed with the no cut treatment (2.18) and in the variety RD 2552 (1.61). Delay in cutting for green fodder decreased the regenerating capacity and consequently the grain yield of barley for dual purpose. The varieties viz. RD 2552 and RD 2715 out yielded than the BH 393 and BH 946, which are commonly used for feed purpose in north-western plain zone of the country. Although no-cut is more economical but in fodder scarcity conditions, RD 2552 and RD 2715 varieties of barley may be recommended as dual purpose.
Key words: Barley, cutting management, grain and straw yield, NDVI and varieties
