Abstract

Mustard (Brassica juncea L.) is a horticultural plant that acts as a source of vitamins and minerals. For this reason, mustard cultivation needs to be developed. The development of mustard cultivation can be done through the selection of the right planting media to support the growth of vegetable crops, especially on limited land. This study aims to study the effect of differences in the composition of the growing media on the growth and yield of mustard greens. The study was arranged in a completely randomized design consisting of four treatments. The treatment consisted of media: A = soil; B = soil + manure (1:1); C = soil + manure + compost (1 : 1 : 1); D = soil + manure + sand (1 : 1: 1). Each treatment was repeated four times to obtain 16 experimental pots. Variables observed: Plant height (measured 2 and 4 weeks after transplanting seedlings), Number of leaves (measured 2 and 4 weeks after transplanting seedlings), Wet weight of mustard greens (weighed at harvest). The data were analyzed using analysis of variance and if there was an effect of treatment, it was continued by using the BNT test at the 5% test level. The results showed that the planting medium given manure gave the best growth and yield of mustard greens. The composition of the planting media, soil + manure + compost (1 : 1: 1) is good for the cultivation of mustard plants.

Abstract

ABSTRACT This study aims to study the effect of paclobutrazol on the growth and production of tomato plants. The research was conducted at the Experimental Garden of the Pandu Agricultural Technology Assessment Center in Talawaan Bantik Village, Wori District, North Minahasa Regency. Starting from September 2017 and ending in January 2018. This study used a randomized block design consisting of 6 levels of paclobutazol concentrations of 0 ppm, 75 ppm, 100 ppm, 125 ppm, 150 ppm, 175 ppm. Variables were observed for plant height, time / time of flowering (days after seeding), number of crop collections, and fruit weight. The use of paclobutrazol in tomato plants has a significant influence on plant height at flowering and number of leaves. The administration of paclobutrazol with a concentration of 125 ppm gave the greatest emphasis which produced the lowest plant height of 47.75 cm.  The use of paclobutrazol in tomato plants can delay the flowering process compared to without using paclobutrazol. The effect of paclobutrazol on flowering is a secondary influence, while the primary effect is suppression of vegetative growth. Keywords: Application of Paclobutrazol in Tomato Plants
