Abstract

Growing medium influence plant growth and development. The purpose of this study was to determine the best growing medium used in the nursery of pepper (Piper nigrum L.). The experiment was conducted by using a randomized block design (RBD) with treatment: P0: subsoil, P1: subsoiland manure (2: 1), P2: subsoil and sand (2: 1), P3: subsoil, manure and sand (2: 1: 1), P4: topsoil, P5: topsoil and manure (2: 1), P6: top soil and sand (2: 1), P7: topsoil, manure and sand (2: 1:1). There are 8 treatment, 4 replicates of each treatment was repeated. Each experimental unit comprises 3 cuttings, cuttings planted each polybag, so there are 32 experimental units  with overall there are 96 polybags. Based on the results of the study there were significant differences among the medium on the growth observed variables: shoot height, number of leaves, shoot diameter, shoot dry weight and root dry weight. Subsoil + manure (2: 1), subsoil + manure + sand (2: 1: 1), topsoil, topsoil + manure (2: 1), topsoil + manure + sand (2: 1: 1) provide good growth on cuttings of pepper, so it can be used in the nursery cuttings pepper.Keywords :pepper cutting, planting medium, seedling growthPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/22

Abstract

The aim of this research is to analyse the effect of the number of buds per stem cutting on vegetative growth, especially from germination phase to budding phase of sugarcane GMP2 and GMP3 varieties. Research carried out in the garden practices of The State Polytechnic of Lampung, Rajabasa, Bandar Lampung in November 2014 to February 2015. The research method used a factorial randomized block design, consisting of two factors. The first factor was the sugarcane varieties, i.e. GMP2 and GMP3. The second factor was the amount of buds from stem cutting which consists of 4 levels: 1, 2, 3, and 4 buds per stem cutting. Based on the results of this research there was no interaction between variety and number of buds from stem cutting. Varieties affected on plant height, number of leaves, number of tillers, length of roots shoots (butters roots) and roots length rope (rope system roots). While the number of buds seeds mule had no effect on plant height, number of tillers, stem diameter, length of roots surface (superficial roots), and heavy roots.Keywords: number of buds, stem cutting, sugarcane varietiesPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/33

Abstract

The sugarcane (Saccharum officinarum L.) is the plant that worth high economical enough, because is the main raw material in manufacture of sugar. One of the efforts to increase the sugarcane production is applying organic fertilizer that can support the growth of sugarcane. The organic fertilizer is fertilizer that's mostly or entirely consist of organic material that from plants or animals that have through the decomposition process, it's can be solid or liquid which is used to supply organic material to improve the physical, chemical and biological soil. It's carried in the garden at Politeknik Negeri Lampung in September 2014 until January 2015. The experiment were performed using a randomized design group (RDG) factorial design which consists of two treatment factor is dosage of organic fertilizer and sugarcane varieties. The first was treatment    dose of organic fertilizer that consists of  5 levels, it’s 0 kg.ha-1 (control), 500 kg.ha-1, 1000 kg.ha-1, 1500 kg.ha-1, and 2000 kg.ha-1. The second factor is a sugarcane varieties, it'sGMP 2 and GMP 3 varieties.  The study aims to get the optimal dose of organic fertilizer (Ghaly Organik), the best sugarcane varieties and knowing the interaction between the treatmenton vegetative growth of sugarcane. The result showed that the optimal dose that was applied on GMP 2 and GMP 3 varieties is 1000 kg.ha-1. GMP 2 Sugarcane varieties have better vegetative growth as compare with GMP 3sugarcane varieties. There is not interaction that happened between treatment dose of organic fertilizer and sugarcane varieties.Keywords : organic fertilizer, sugarcane varieties, vegetative growthPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/44
