Abstract

Cocoa (Theobroma cacao L.) is one of the estate crop commodities that is currently being developed because the cocoa plant is one of the export commodities that produce a lot of foreign exchange and has a role as high value sector besides oil and gas. Cocoa farming can increase the income of cocoa farmers, create and expand employment. This experiment used Randomized Block Design (RBD) which consisted of 4 treatments that was repeated 6 times (control, 1 tablet.polybag-1, 2 tablet.polybag-1, 3 tablet.polybag-1). This study was conducted to determine the best rate of compound fertilizer tablets for cocoa seedlings growth. The data obtained were analyzed by analysis of variance at 95% accuracy level. The results showed that there was a compound effect on the growth of cocoa seedlings to the variable of seed height, stem diameter, leaf number, leaf area, dry root weight, and total dry weight of stalk. Application of tablet compound fertilizer 1 tablet.polybag-1 gives the best results on the growth of cocoa seedlings.     Keywords: cocoa seedlings growth, inorganic fertilizer, tablet compound fertilizerPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/647

Abstract

There are many benefits of sugarcane (Saccharum officinarum L.) as a sugar source to fulfil human staples food. The use of sugarcane bud chips is one of cultivation technology in order to achieve national sugar self-sufficiency program. Bagasse mulch kept soil moisture and increased organic matter in the soil thathas positive impact on sugarcne growth. The experiment was conducted in Teaching Farm of the State Polytechnic of Lampung, from November 2015 until April 2016. The experiment used Randomized Block Design (RBD) in factorial pattern, consisting of two factors. The first factor is the treatment of bud chips position consisting of 3 levels i.e. top bud chip, middle bud chip, and bottom bud chips. The second factor is the bagasse mulch treatment consisting of 4 levels i.e. control, 3 ton.ha-1, 6 ton.ha-1, and 9 ton.ha-1. The objectives of the study were to obtain optimal growth among bud chips, optimal bagasse mulch, and to know the interaction between the bud chips position and the bagasse treatments. The results showed that the top bud chips were better than  middle bud chips and bottom bud chips. The optimal rate of bagasse mulch was 3 ton.ha-1. There was an interaction between the treatment of sugarcane bud chips and mulch bagasse on leaf length and soil moisture growth.   Keywords: bagasse mulch, bud chips, sugarcane seedlingsPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/648
