Effects of foliar application of paclobutrazol and seaweed fertilizer on yield and quality of peanut types

For high yield and quality of peanut,field experiments were conducted in 2012 and 2013 to study the effects of paclobutrazol( PBZ) and seaweed fertilizer( SM6) on peanut. 3 cultivars KB008( high protein),Hua 17( H17,high oil),and Nongda 818( 818,high O / L) were used as materials. Results showed that PBZ treatment significantly increased pod yield by improving pod number and pod weight per plant. But PBZ reduced kernel rate and protein content,and decreased O / L of Hua17 and Nongda 818. SM6 treatment had little effect on pod yield of Hua 17 and Nongda 818,but significantly improved pod number and pod yield of KB008. SM6 significantly improved kernel rate,protein content,oil content and O / L of the 3 cultivars. PBZ and SM6 combined application could significantly improve pod yield and kernel quality of 3 different types of peanut.
