Abstract

This study aims to determine the effect of the number of tubers / kg of seeds and the dose of biological liquid fertilizer on the growth and production of potato plants. The research was carried out at the Quality University Experimental Garden in Karo District at + 2140 m asl which was conducted from June 2017 - September 2017. This study used Factorial Randomized Group Design with two treatment factors. The first factor is the size of seed bulbs with four levels, namely: 7 tubers / kg (P1); 14 tubers / kg (P2) and 21 tubers / kg (P3), and the second factor is the liquid fertilizer dosage with four levels: 0.0 ml / l water (Ho); 0.2 ml / l water (H1); 0.4 ml / l water (H2); 0.8 ml / l water (H3). The results showed that the treatment of tuber size as seeds significantly affected the number of tubers / samples of production / samples, production / plots, but not significantly different for plant height, number of branches. The treatment of biological liquid fertilizer doses significantly affected plant height, tuber / sample number, production / sample, production / plot. But it was not significant for the number of branches. The interaction between the two treatment factors did not significantly affect all parameters observed throughout the study.

Abstract

The research was carried out in the Tigapanah Village Farmers' field, Tigapanah Subdistrict, Karo Regency, from March to June 2016, where altitude was ± 1200 meters above sea level, Adosol land. The aim of the study was to determine the chicken manure dosage and the concentration of coconut water and its interaction with the growth and yield of Ercis plants (Pisumsativum L). Factorial Randomized Group Design (RBD) 4 levels, factor I: dose acquisition 1) without manure (control) 2) chicken manure 2) 200 g / plant, 3) 300 g / plant, 4) 400 g / plant (A0 , A1, A2, and A3). Factor II. Concentration of coconut water 4 level 1) 0 ml / plant, 2) 100 ml / plant, 3) 200 ml / plant, 4) 300 ml / plant (K0, K1, K2, K3). The results of the study showed that the effect of using chicken manure was significantly different (p ˃ 0.05) on the growth of plant height, number of branches, pods and weights of Ercis plants except that the age began to flower. Giving a dose of coconut water also gave a significantly different effect (p ˃ 0.05) on the growth of plant height, number of branches, production of pods and production weights except age began to flower. The interaction of doses of chicken manure and doses of coconut water did not have a significant effect on all observed parameters.

Abstract

AbstrakPerubahan yang terjadi pada buah merupakan kerusakan buah yang disebabkan karena proses respirasi dan transpirasi. Penelitian bertujuan untuk mengetahui konsentrasi penambahan gliserol dalam edible coating yang dapat menekan kerusakan buah pisang barangan selama penyimpanan dan menentukan daya daya simpan untuk mempertahankan kualitas buah. Rancangan Acak Lengkap digunakan yaitu 5 perlakuan dan 4 ulangan. Parameter yang diamati persentase di antaranya susut bobot, vitamin C, dan total asam. Hasil penelitian menunjukkan lama penyimpanan dan konsentrasi gliserol dalam edible coating yang berbeda berpengaruh nyata (p < 0.05) terhadap susut bobot, kandungan vitamin C, dan kadar total asam pada hari ke 9, 12 dan 15 dan  tidak berbeda nyata pada hari ke 3 dan  ke 6 (p > 0.05).AbstractThe fruit of pisang barangan (Musa acuminata L) is one of the short shelf life storing agriculture products. Physically changing of the fruits is a kind of fruit abolishes activated by the respiration and transpiration process. The effort to prevent the process can be the use of covering glycerol edible coating. The proposed of this study is to know the additional concentration of glycerol in an edible coating that prevents damages of the fruits along with storing and determining its storing capacity. The research was using complete design with 5 treatments and 4 duplications. The parameters observed were the percentage of rigorous, vitamin C, and acid total. Results of the study shown that the length of storing was significantly reducing the quality of the fruits and the glycerol concentration in edible coating has significantly impact (p < 0.05) to the grade of rigorous, vitamin C, and the acid total in day of 9th, 12th, and 15th; while in day of 3th and 6th shown likewise.

Abstract

This reserch aims to determine the effect of comparison of planting media and and growth regulator concentration on the growth and propagation of G-0 Potato seeds. This research was carried out in the Screen house of the Raya Village garden, Berastagi District, Karo Regency, North Sumatra Province, with a place of ± 1,300 m asl. This research was carried out from January to April 2019. This reserch used the Factorial Randomized Block Design method of two treatment factors, namely the comparison treatment of planting media with the symbol "M" which consists of five levels, namely: without compost (M0 ), 30% compost (M1), 50% compost (M2), 70% compost (M3), and 100% compost (M4). The second factor was giving a growth regulator concentration with the symbol "Z" which consists of three levels, namely: without concentration (Z0), 1.5 ml /L (Z1), and 3 ml / L (Z2). So that 15 treatment combinations were obtained, each treatment was repeated 3 times. The results of the observational data were then analyzed for variance with an F level of 5%. If there is a significant difference (p <0.05), then the test is continued with the Duncan test. The results showed that the treatment comparison of the planting media had a significant effect (p <0.05) on the variable growth in plant height, development of stem diameter, production each sample, and production each plot, and had no significant effect (p> 0.05) on number of branch. The treatment of growth regulator concentration had a significant effect (p <0.05) on production variables each sample, and production each plot, and had no significant effect (p> 0.05) on variable growth in plant height, development of stem diameter, and number of branch.

Abstract

This study aims to determine the ZPT and POC intractions that can affect the growth and production of onion plants. This reserch was carried out in Gurubenua Village, Munte District, Karo Regency, Nourth Sumatra, with a height of ±1175-1350 meters above sea level. This research was conducted from June 2019 to September 2019, using the Factorial Randomized Block Design (RBD) method consisting of two regulatory factors, the first dose of ZPT with symbol A consisting of 4 levels, namely: No dosing (A0), 0,75ml/ liter of water (A1), 1,5ml/ liter of water (A2), and 2,25ml/ liter of water (A3). Second is the POC dose with the symbol P consisting of 4 levels, namely: Without dosing (P0), 1,5ml/ liter of water (P1), 3ml/ liter of water (P2), and 4,5ml/ liter of water (P3). Approved, 16 preparations were obtained, with two replications. The data analyzed the F test variance at the 5% level. If there is a significant difference (p˂0.05), then try to continue with the DMRT test. The results of the studyprove the need for a real implementation of ZPT (p˂0.005) for height plant variables per sample, number of leaves per plotand number of tubers per plot, and not significant (p˃0.005) for variable measurements of tuber diameter per sample, plant weight per sample and plant weight per plot. The treatment of submitting POC must be real (p˂0.005) of the plant height variable per sample, number of leaves per sample, number of tubers per sample, and plant weight per sample and not significant (p˃0.005) to the variable influence of tuber diameter per sample and plant weight per plot.
