Understanding about the combinations of agronomic options can be used to improve the fodder and grain yield of dual purpose wheat varieties is limited. An experiment involving three
management strategies was conducted during Rabi season of 2020-2021 at Research farm of CCSHAU Regional Research Station, Rohtak, to evaluate changes in fodder and grain yield of dual purpose wheat varieties. The soil of the experimental field was sandy loam in texture, neutral in reaction, low in organic carbon and available nitrogen, medium in available phosphorus and high in available potassium. The experiment was laid out in split plot design with two varieties viz. V1 : VL289 and V2 : C306 and six seed rate x cut treatment at 55 DAS viz. S1 : 100 kg/ha. without cut, S2 :100 kg/ha with cut, S3 :112.5 kg/ha without cut, S4 :112.5 kg/ha with cut, S5 :125 kg/ha without cut and S6 : 125 kg/ha with cut in main plot and three fertility levels viz. F1 : 100% RDF (60 kg N/ha+30 kg P2O5/ha), F2 : 20% higher than RDF and F3 : 50% higher than RDF in subplot replicated thrice. Results revealed that among both the dual purpose wheat varieties, VL 829 recorded taller plants with 33.51 % higher grain yield than C 306. Among various seed rate × cut treatments, highest green fodder yield was recorded in seed rate of 125 kg/ha with cut while highest grain yield was recorded in 125 kg/ha without cut treatment which was at par with 100 kg/ha and 112.5 kg/ha without cut treatments. Fodder yield increased significantly with increase in fertilizer dose from 100 % RDF to 150 % RDF. Application of 150 % RDF being at par with 120 % RDF recorded significantly higher grain yield with better yield attributes of wheat. The B: C ratio calculated was higher in wheat variety C 306 and application of 150% RDF. Among various seed rate × cut at 55 DAS, highest B: C was recorded with 125 kg/ha without cut treatment.
Key words: Dual purpose wheat, fodder yield, grain yield and BC ratio
