Abstract

Tatsoi is included in the Brassicaceae family which contains protein, fat, fiber, calcium and several vitamins making the tatsoi an exclusive vegetable. Tatsoi is not widely cultivated by farmers, so there are not many guidelines for the cultivation. To increase the growth and yield of tatsoi  can be done using mulch and Liquid Organic Fertilizer. This study aims to determine effect of the thickness of rice straw mulch and variations  concentration of liquid organic fertilizer on the growth and yield of tatsoi. The research was conducted at the STIPER Dharma Wacana experimental garden from November to December 2018. This study used a randomized block design in two factors. The first factor is the thickness of straw mulch which consists of 3 levels (without mulch, rice straw mulch 10 tonnes/ha, and rice straw mulch 20 tonnes/ha). The second factor is the concentration of liquid organic fertilizer which consists of 3 levels (control,  2 ml / l, and 4 ml / l). The results showed that the thickness of the rice straw mulch had no significant effect on the growth and yield of Tatsoi. The addition of 2 ml / l and 4 ml / l liquid organic fertilizer  significantly increased the growth and yield of tatsoi compared without liquid organic fertilizer  as indicated by the variables of plant height, number of leaves, crown diameter, yield per plot, wet weight salable yield, and  yield per hectare. There is no interaction between the two factors.

Abstract

Dragon fruit is one type of plant that is quite popular in Indonesia because of its sweet taste and high selling price. Dragon fruit has various types, including dragon fruit with red flesh, white flesh with yellow skin color and red skin with white flesh. Dragon fruit contains high betacharotene and antioxidants to prevent cancer and ward off free radicals. The fiber content in it can facilitate digestion, prevent colon cancer, and cope with diabetes. The objectives of this study were to determine effect of length stem cuttings on the growth of red dragon fruit cuttings, effect of different methods of giving between immersion and watering coconut water on the growth of dragon fruit cuttings, and interaction lengths cuttings and how to give coconut water to the growth of dragon fruit cuttings. The results showed that red dragon fruit stem lengths of 25 cm and 30 cm give better results than 15 cm and 20 cm.  Dragon fruit stem lengths of 25 cm and 30 cm had a significant effect on bud emergence variables, number of shoots, average shoot length per cuttings and number of roots, but the root length variables, root wet weight and root shoot ratio were not significantly different. The method of giving coconut water shows that watering is better than soaking. but on the variable number of shoots per cuttings, the average length of shoots per cuttings,  root  wet  weight  and  root  crown  ratio  had  no  significant  effect.  There  is  no interaction between rod length and means giving coconut water to the growth of red dragon fruit cuttings on all observed variables.

Abstract

This research aimed to find out the effect of the number of plants per hole on the growth and yield of hydroponic pakcoy plants. The study was carried out in the STIPER Dharma Wacana Metro greenhouse from May to June 2018. The treatments tested were one plant, two plants, three plants, and four plants per hole. The hydroponic system used is the Nutrient Film Technique (NFT) system. The variables observed were plant height, number of leaves, widest leaves, stem diameter, total plant weight, and root weight. The results showed that the treatment of one plant per hole produced better growth than other treatments with plant height of 23.65 cm, number of leaves 12.1 strands, crop diameter 5.59 cm, and longest root 38.25 cm.

Abstract

Shallots are one type of vegetable plant that has the potential to be cultivated in polybags to be used as filling plants in the yard of the house. The aim of the study was to determine the best dose of KNO3 fertilizer for the growth and yield of shallots in polybags. The treatments used in this study were unfertilized (0 g polybag-1), 0,3 g polybag-1, 0,6 g polybag-1, 0,9 g polybag-1, 1,2 g polybag-1, 1,5 g polybag-1, and 1., g polybag-1. The results showed that the treatment used had a significant effect on the growth and yield of shallots, especially on the variables of tuber diameter, dry bulb weight harvested per clump, and average dry weight harvested per tuber. KNO3 treatment dose of 0.9 g polybag-1 was the best treatment to increase the growth and yield of shallots in polybags

Abstract

The cultivation of Red Onions (Allium ascalonicum, L.) in paddy fields needs to be investigated further because paddy fields have constraints on the soil physical and chemical properties, such as soil structure, drainage, pH, and nutrient availability. The application of husk charcoal and K fertilizer is expected to increase the productivity of Red Onions, so it is necessary to study the appropriate dose. The research aimed to determine the effect of the interaction between the application of husk charcoal and KCl fertilizer and the influence of each factor on the growth and yield of Red Onions. The results showed that rice husk charcoal treatment at a dose of 20 Mg ha-1 was effective in increasing the growth and yield of Red Onions compared to rice husk charcoal at a dose of 10 Mg ha-1 and 0 Mg ha-1 (control), as evidenced by the variable shallot plant height, number of leaves, number of tubers per clump, wet tuber weight per clump, and tuber dry weight per clump. KCl fertilizer treatments at doses of 100 kg ha-1, 200 kg ha-1, and 300 kg ha-1 did not significantly affect to growth and yield of Red Onions. There was not interaction between the rice husk charcoal and KCl fertilizer treatments.
