SUMMARY
The experiment was conducted at Sorghum Agronomy Block of Instructional Dairy Farm, Nagla, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Udham Singh Nagar, Uttarakhand (India) during kharif seasons of 2015 and 2016 to evaluate fodder based intercropping systems for various quality and yield traits of fodder. Ten treatments as detailed in materials and methods section were tested in three replications following randomized block design. The analysis of data indicated that all cell wall structural components (NDF/ADF/hemicelluloses) showed positive correlation with each other. NDF and ADF were existed negative association with cell content, CP content, DDM, DMI, TDN, RFV, NEl and mineral content. CP content was significantly and positively associated with DDM, DMI, TDN, RFV and NEl while negative association with cell wall structural components (ADF/NDF/ hemicellulose). DDM was positive correlation with cell content, DM content, CP content, DMI, TDN, RFV, NEl and mineral content. DMI and RFV were negative association with cell wall structural components. The CPY and DDMY were positively and significantly correlated with DM content, cell content, CP content, DDM and mineral content. DM content was positively correlated with all yields (GFY, DFY, DDMY and CPY) and this association was significant. The CPY and DDMY were positively and significantly correlated with DM content, cell content, CP content, DDM and mineral content. Association of cowpea with sweet sorghum improved the quality of fodder. Sweet sorghum+cowpea system provided higher green fodder, dry fodder, crude protein and digestible dry matter yield under Tarai agro climatic situation of Uttarakhand.
Key words:Correlation, crude protein content, dry matter intake, hemicellulose, net energy
