Abstract

The objective of this research is to measure the effect of giant salvinia compost and compound fertilizers on growth of cocoa seedlings. This research has been conducted in State Polytechnic of Lampung experimental garden, Rajabasa, Bandar Lampung on December 2014 until May 2015. The method used was a randomized block design (RBD). The factorial pattern consisting of two factors. The first factor was the rate of giant salvinia compost consists of four levels, namely: K0 = 0 g.polybag-1, K1 = 200 g.polybag-1, K2 = 300 g.polybag-1, and K3 = 400 g.polybag-1. The second factor was the rate of compound fertilizer consists of two levels, namely: M0 = 0 g.polybag-1, M1 = 5 g.polybag-1, M2 = 10 g.polybag-1. Data were analyzed by analysis of variance further significantly different if followed by LSD test at the 5% level of accuracy. Observations included plant height, number of leaves, stem diameter, root length, dry weight, and ratio of root-shoot dry weight. The results showed that giant salvinia affected on plant height, number of leaves, stem diameter, root length, and the ratio of root-shoot dry weight. Compound fertilizer also affected on plant height and number of leaves, stem diameter, root length, and and ratio of root-shoot dry weight. There was an interaction between rate of giant salvinia compost and compound fertilizer on length root.Keywords: compound fertilizer, giant salvinia compost, Theobroma cacao L.Permalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/18

Abstract

NPK fertilizer and organic fertilizer on the growth of oil palm seedlings in the main nursery aims to determine a single effect or interaction between the two on the growth of oil palm seedlings in the main nursery.  The experiment was conducted at the Polytechnic of Lampung from July 2013 to March 2014.  The study used Complete Randomized Design (CRD) factorial, which consists of two factors and each combination was repeated 3 times.  The first factor of NPK fertilizer with 3 levels, 100%, 50%, and 25% of the dose recommendation as much as 142 g.  The second factor is the dose of organic fertilizer (Organonitrofos) with 3 levels of treatment, without organic fertilizer, 18 g polybag-1, and 36 g polybag-1. Observation variables such as plant height, number of midrib, stem diameter, length of midrib, shoot dry weight, root dry weight and P total.  The results showed that NPK fertilizer at the age of 9 months to increase the length midrib, shoot dry weight and root dry weight. Effect of dosage of the best there is at 100%.  The combination of NPK fertilizer and organic fertilizer there is an interaction of the dry weight of the roots and the best interaction was achieved by treatment of 50% NPK fertilizer and organic fertilizer  36 g polybag-1.Keywords: NPK fertilizer, oil palm, organonitrofosPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/20

Abstract

Cocoa plants are plantation crops that have high economic value and stable. Cocoa prospects quite good because the market demand is very big commodity. The research was conducted in field trials, Lampung State Polytechnic, from  September 2014 up to February 2015. Experiments conducted with factorial randomized block design with 2 factors and any combination treatment was repeated three times. The first factor, namely the provision of oil palm fiber to the growing media consisting of 0% oil palm fiber and 100% soil, 25% oil palm fiber and 75% land, 50% oil palm fiber and 50% of the land. The second factor, namely the provision of liquid organic fertilizer of cow urine which consists of 0 ml of cow urine, cow urine of 40 ml, 80 ml of cow urine, cow urine and 120 ml. This study was conducted to determine the effect of oil palm fiber and cow urine, as well as the provision of fiber interactions palm and cow urine on the growth of cocoa seedlings. The results showed the provision of oil palm fiber 0% gives better results than the 25% and 50% in high-seed, stem diameter, number of leaves, dry weight and root length stover. Giving cow urine of 40 ml to 120 ml showed better results than without the provision of cow urine on seedling height, stem diameter, number of leaves, dry weight stover, and root length. In general, oil palm fiber giving no effect on the growth of cocoa seedlings and cow urine giving a dose of 40 ml to 120 ml to give effect to the growth of cocoa seedlings. There is interaction granting palm fiber and cow urine on a number of leaves and length of plant roots.Keywords: cocoa seed, cow urine, fiber palm oilPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/25
