Abstract
A field experiment was conducted to study the effect of intercropping and nitrogen levels on biometric growth parameters and yield of forage sweet sorghum at AICRP on Sorghum, Main Agricultural Research Station, Dharwad during kharif season of 2015. The experiment was laid out on medium black soil in randomized complete block design with fifteen treatments and three replications. The results of the experiment indicated that intercropping of sweet sorghum + horsegram (2:1) with 100 % RDN recorded significantly higher total dry matter production (71.23 g/plant), LAI (7.72), LAD (106.3 days) and NAR (0.0737 g/dm2 /day1) as compared to others. The same treatment produced significantly higher total green and dry forage yield (49.08 and 12.81 t/ha respectively) and LER (1.36) followed by sweet sorghum + horsegram (2:2) with 100 % RDN due to higher growth and yield attributes.
