PENGARUH PEMBERIAN PUPUK ORGANIK TERHADAP PERTUMBUHAN BEBERAPA BENIH ASAL KLON KAKAO (Theobroma cacao L.) DI PEMBIBITAN

Abstract

This study aims to determine the growth response of some kind of clone of cocoa ( Theobroma cacao L. ) with an organic fertilizer in a polybag with using randomized block design (RBD ) factorial with 2 factors studied , namely : The first factor is Organic Fertilizer ( O ) divided into 3 levels ie O0 = Without Giving , O1 = Amazing Bio Fertilizer Growth ( ABG ) and O2 = Fertilizer Super Bionic , and the second factor varieties Cocoa ( K ) is divided into three types namely TSH K1 = 858 , K2 = 70 and K3 = RCC PA 300 . While the parameters measured were plant height ( cm ) , number of leaves ( blade ) , stem diameter ( mm ) , leaf area ( cm ) , root fresh weight ( g ) , stem fresh weight ( g ) , root dry weight ( g ) , stem dry weight ( g ) and root volume ( cc ) . The results showed that the use of organic fertilizers provide a significant effect on the parameters of plant height , leaf number , stem diameter , leaf area , stem fresh weight , and root volume and provide no real influence on the parameters of the wet weight of the rod . Treatment varieties only significant effect on plant height parameters , and no real influence on the other parameters .While the interaction of treatment showed a marked influence on the parameters for a high cocoa seedlings and other parameters showed no real difference.
