Abstract
A study on the use of green manure and phosphorus Calopogonium mucunoides the agronomic properties and yield components of sweet corn (Zea mays saccharata Sturt) in the experimental garden of the Faculty of Agriculture, University of Riau. This study aims to determine the interactions giving Calopogonium mucunoides legumes as green manure and fertilizer phosphorus (P) for some agronomic properties and yield components of sweet corn and get the best dose. The research was carried out experimentally in a 4 x 3 factorial arranged in randomized block design (RBD). The first factor is the dose of C.mucunoides (L) in 4 standard, namely: L0= without giving C. mucunoides, L1= 5 tons/ha C. mucunoides, L2= 10 tonnes/ha C. mucunoides, L3= 15 tonnes/ha C.mucunoides. The second factor is the dose of fertilizer phosphorus (SP-36) in the third stage are: P0= without giving P2O5, P1= 15 kg/ha P2O5, P2= 30 kg/ha P2O5. The results showed that treatment of green manure and fertilizer C.mucunoides P (SP-36) which is applied to the corn crop influence on agronomic properties and some yield components of sweet corn crops. The rate of plant growth, root crown ratio and dry weight of sweet corn crops are the best treatment C. mucunoides green manure 15 tonnes/ha and 30 kg/ha of fertilizer P. Production cob /plots best obtained at treatment C. mucunoides green manure 10 tonnes/ha and 30 kg/ha of fertilizer P with results of 3.36 kg/plot, equivalent to 11.20 tonnes/ha.
