Abstract

One of the ways to increase cucumber production is through intensive cultivation techniques with a shoot pruning system and the application of organic fertilizers. The focus of this research is to optimize fruit quality and quantity. This research was conducted at Jalan Anggrek II Simpang Selayang, Medan Tuntungan District, Medan City, North Sumatra, starting in December 2023 until February 2024, using a Randomized Group Design (RAK) consisting of two factors. Parameters observed in this study were the number of fruits per plant, weight per fruit, fruit weight per plant, fruit diameter and fruit length. Based on the results of the study, it can be concluded that pruning shoots at the age of 29 days after planting significantly increases the number of fruits per plant, weight per fruit, fruit weight per plant, fruit diameter and fruit length. Doses of chicken manure significantly increased the number of fruits per plant, weight per fruit, fruit weight per plant, fruit diameter and fruit length. The interaction between shoot pruning and manure dose had no significant effect on all parameters observed. Pruning shoots at the age of 29 days after planting increased the number of fruits per fruit by 9.06%, increased fruit weight per plant by 19.78%, increased fruit weight per plot by 28.35%.

Abstract

This research aims to describe the production of Granola Variety potato seeds from tissue culture (plantlets) and mini cuttings in the Taruna Bina Tani green house in Bukit Village, Dolat Rakyat District, Karo Regency. The observation technique is carried out by direct observation and running a questionnaire. Mini cuttings plants sourced from plantlets will have the same genetic characteristics as their parents, meaning that even though the shoot stem cuttings are small, the results of propagation using the mini shoot cuttings system are also the same as plants originating from tissue culture seeds (parent seeds). Toruna Bina Tani is one of the producers of virus-free Granola Variety potato seeds in Tanah Karo. This business started in 2018. The breeding screen house covers an area of 5000 meters which actively produces generation 0 (G0) to generation 2 (G2) potato seeds which are distributed to farmers.The results showed that the growth of plantlets and mini cuttings was not different, the production of the number of plantlet tubers was greater than the production of the number of tubers of mini cuttings, on the other hand, the weight of tubers per plant, the weight of tubers per tuber and the weight of tubers per rack were smaller in plantlets than in mini cuttings. . Propagation via mini cuttings taken from plantlets is very effective in accelerating the fulfillment of quality seeds (G0). Each individual plantlet can produce 83.8 mini cuttings.

Abstract

Chili, which is one of the seven national strategic commodities, shows fluctuating export figures and import figures that tend to increase. It is necessary to implement a cultivationtechnology to increase the growth of chili plants. One technique for cultivating chilies usesecoenzymes. Research to see the effect of ecoenzymes on the growth of cayenne pepper plants hasbeen carried out. This research used a factorial Randomized Block Design (RBD), namelythe first factor was the ecoenzyme concentration consisting of 4 treatment levels, namely: K0 : 0ml/500 ml water, K1 : 15 ml/500 ml water, K2 : 30 ml/500 ml water, K3: 45 ml/500 ml water. The second factor is the frequency of ecoenzymes consisting of 3 treatment levels, namely: F1: 1time a week, F2: 2 times a week, F3: 3 times a week. Statistical testing was carried out by compiling a list from analysis of variance. For treatments that had a significant effect, a mean difference test was carried out with an honest significant difference test at the 5% level and continued with regression analysis. The parameters observed were plant height (cm), number of leaves (strands),stem diameter (cm). The results showed that both concentration and frequency factors did not have a significant influence on all parameters except the number of leaves parameter. The increasing ecoenzyme concentration to 45 ml/500 ml of water increased the number of leaves by 49.59 pieces.
