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

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.
