Abstract
The effect of diclosulam WDG on plant growth, nodulation and crude protein content of greengram was studied during the kharif season of 2014 at Raichur (Karnataka). The pre-plant surface application of diclosulam @ 17.5 and 27g a.i. ha-1 adversely affected the parameters because of its phytotoxic effect. Premergent application of pendimethalin 1.5 kg a.i. ha-1 and diclosulam 17.5 g a.i. ha-1 increased the total dry matter production (17.64 and 17 g/plant) among the herbicidal treatments. Pendimethalin 1.5 kg a.i. ha-1 recorded increased the number of effective nodules formed per plant (22.93 and 59.63) and 22.06% of average maximum crude protein content compared to all the herbicide treated plots. In contrast, the pre-plant surface application of diclosulam 27g a.i. ha-1 lower number of effective root nodules (12.47 & 44.80) @ 30 and 60 days respectively, and minimum crude protein content (21.54%). Among the different methods of application, diclosulam pre-plant surface application showed a large degree of phytotoxicity to the crop.
