Impact of bio-fertilizers and chemical fertilizers on yield and yield attributes of pumpkin (cucurbita moschata) in lower Assam

(Highest Pumpkin fruit yield (q/ha) was recorded by the treatment T7 followed by T5treatment and both this two treatments were found at par and significantly superior to rest of the treatments. Highest vine length(m),Total leafs/vine and Fruit yield(q/ha)were recorded by the treatment T7 (30% Field soil+30%Vemicompost+40%Jeevamrit).Highest net return(Rs/ha)was also recorded by the treatment T7 (2,16,750=00) followed by the treatment,76 (1,92,900=00),T5 (2,16,375=00),T4 (1,91,813=00),T3 (1,80,750=00),T2 (1,57,688=00) and T1 (1,54,011=00).Experimental soil was Loamy textured soil with pH-5.25 to 5.36,Available N(kg/ha) was Low to Medium, Available P2O5 (kg/ha) was Low and Available K2O was medium to high. Av. rainfall during this crop growing period was 870mm to 950mm with the air temperature varies from 300C-360C.Relative humidity was found almost 82% during the vege) tative period of Pumkin crop)
