Research on Peanut Yield Increase Effect through Calcium Cynanamide Application

The test of applying calcium cyanamide on peanut led that the number of branches and dual-kernel pod increased,the condition of vegetative growth improved,100-pod weight,100-seed weight and shelling percentage increased,and the yield and economic benefit of peanut raised. Compared the treatment applying calcium cyanamide 75 kg per hectare with the control treatment,the number of branches increased 3.6 and pods increased 2.2 per plant,the weight of 100-pod increased 21 g,100-seed weight increased 11.9 g,shelling percentage enhanced 2.8%,yield enhanced 24.7%,and net income increased 4640 yuan per hectare.
