The composition of the growing media and the frequency of watering can be used as a way to increase the productivity of pakcoy plants. A study was conducted to determine the effect of planting media composition and frequency of watering on the growth and yield of pakcoy (Brassica Rapa L.) on entisol soil in the greenhouse of the Faculty of Agriculture, the University of Timor in April to August 2021 using a factorial completely randomized design consisting of two factors which were repeated 4 times. The first factor consisted of 3 levels, namely soil without biochar compost (K0), 50% biochar compost + 50% entisol soil, (K1), and 75% biochar compost + 25% entisol soil (K2). The second factor consisted of 3 levels, namely the frequency of routine watering in the morning and evening (F0), the frequency of watering every 2 days in the morning and evening (F1), watering every 4 days in the morning and evening (F2). The results showed that the treatment of planting media and the frequency of watering had a significant effect on each parameter and positively interacted with the parameters of the degree of soil acidity. Treatment of planting media dose of 50% biochar compost + 50% entisol soil was the best treatment in increasing the growth and yield of pakcoy plants. The frequency of watering for 4 days in the morning and afternoon was the best treatment in increasing the growth and yield of pakcoy plants.

Introduction: This study aimed to determine the growth of pakcoy at the time of fertigation and the composition of the verticulture system planting media with different spacing of planting holes and their interactions on dry land. Methods: The method used is an experiment using a Split Plot Design using 3 plots. The main plot is the spacing of the planting holes consisting of 15 cm, 20 cm, and 25 cm. The subplot is the composition of the growing media consisting of soil:sand, soil:biochar; sand:biochar; and soil:sand:biochar. The sub-sub plot is fertigation time which consists of 60 seconds, 90 seconds, and 120 seconds. A total of 36 treatments were repeated 2 times for a total of 72 treatments. Results: Results: The results of this study showed that the interaction of fertigation time significantly affected the growth of plant height, number of leaves and fresh weight of crown with the best combination treatment of 120 seconds of fertigation time with soil:biochar growing media. Fertigation time has a significant effect on all observation parameters, with the best treatment being fertigation for 120 seconds. The composition of the growing media had a significant effect on the observations of plant height, the number of leaves, and the fresh weight of the crown with the best results found in soil: biochar growing media (1:1). Conclusion: The best combination result is a fermentation time of 120 seconds and the composition of soil and biochar (W3M2).

Oenenu Induk village has the potential for monoculture farming that needs to be developed because it has fertile land and has natural resources such as water and a climate that allows kale to thrive. The advantages of monoculture farming systems are that they can increase agricultural yields and also have greater growth and yields than competition between other crops. The purpose of this activity is to introduce monoculture cropping patterns by optimizing narrow land with satisfactory results, to improve the literacy of farmer groups with these crops and to determine the efficiency of use. The method used is training and mentoring. Monoculture cropping patterns can simplify the process of cultivating kale and increase production.

The purpose of this study was the effect of combination doses of Organic (chicken) and Anorganic (Urea, SP36 and KCl) fertilizers on the growth and yield of cucumber plants. the best cucumber plant. This study used an experimental method and the design used was a Simple Randomized Block Design (RAK) consisting of five treatments and five replications. So there are five plots, each repeated five times and each plot having four polybags, so the total number of polybags: 5x5x4 polybags = 100 polybags. With treatment A : Organic (0.12) + Anorganic (Urea 0.55 g/polybag, SP36 0.30 g/polybag, KCL 0.25 g/polybag), B : Organic (0.18) + Anorganic (Urea 0.50 g/polybag, SP36 0.30 g/polybag, KCL 0.25 g/polybag), C: Organic (0.25) + Anorganic (Urea 0.45 g/polybag, SP36 0.30 g/polybag , KCL 0.25 g/polybag), D: Organic (0.31) + Anorganic (Urea 0.40 g/polybag, SP36 0.30 g/polybag, KCL 0.25 g/polybag), and E: Organic (0.37) + Anorganic (Urea 0.35 g/polybag, SP36 0.30 g/polybag, KCL 0.25 g/polybag). The results showed that treatment C could increase the number of leaves and plant height of the Mars cultivar cucumber. Treatment B can increase the number of Mars cultivar cucumber fruit. The application of different chicken manure and Anorganic fertilizers did not affect the fruit weight of the Mars cultivar cucumber.

This study aimed to (i) determine the type of concentration and frequency MOL banana weevil on the growth and yield of melon plants, (ii) to determine the response of melon plants to the use MOL (banana weevil). This research was carried out in June-August 2021, on the land of farmers in mamsena, west Insana sub-district, Regency North Central Timor (TTU). with an altitude of 600 meters above sea levels, rainfall between 2500-4000 mm. the design used in the study was a factorial randomized block design (RAK) consisting of 2 factors with 3 replication, the first factor (K) concentration consisting of (control )g, (K1) 500 ml, (K2) 1000 ml, the second factor (F) frequency of fertilization which consists of: F1 which is 2 times fertilization at planting time (WT) and 14 DAP, F2 is 3 times fertilization at planting time (WT), 14, 28 DAP, F3 fertilizing 4 times: planting time (WT), 14,28,and 42 DAP. Of these two factors, there were 9 treatment combinations, namely K0F1, K1F1, K2F1, K0F2, K1F2, K2F2, K0F3, K1F3, K2F3, so there were 27 experimental units. The result showed (i) the treatment of banan weevil MOL concentration and the frequency of watering had a significant effect on the growth and yield of melon plants. This could be seen from the interaction on the growth parameters, namely plants height 14 DAP, 28 DAP and stem diameter 14 DAP, concentration treatment MOL banana weevil 1000 ml is the best treatment in increasing the growth and yield of melon plantes. This can be seen with the highest values in the parameters of stem diameter, number of leaves, fresh weight fruit per plant, fruith length, fruit diameter, total fresh weight, leaf weight, root weight and harvest index, Treatment frequency of watering 3 times is the best treatment in increasing the growth and yield of melon plants. This can be seen with the highest values for the parameters of stem diameter, number of leaves, fresh weight of fruit per plant, fruit length, diameter of fruit, total fresh weight, and harvest index.

Field rice (paddy field) is one of the important crops/commodities and is an integral part of the dry land farming system in North Central Timor district. The content of rice is to meet the needs of carbohydrates in the body. The materials used are harvested grain from the local North Central Timor rice cultivar which has been carried out for the 2022 planting season. A total of 6 field rice in North Central Timor district were to be tested for Fe and Zn content. Grain samples were taken from crops grown in the same season and location, namely in the dry season of 2022. This study aims to identify local Timorese rice varieties that have high and stable Fe and Zn contents. The study was conducted in the Field Laboratory of the Faculty of Agriculture, University of Timor with a non-factorial Randomized Block Design consisting of 6 cultivar treatments V1 V2 V3 V4 V5 and V6 and the XRF Laboratory, BB Padi Sukamandi. Test the content of Fe and Zn using an XRF machine with an x-ray based performance system. A total of 6 types of field rice were tested for the content of Fe and Zn in brown and polished rice and repeated in duplicate. The content of Fe and Zn is expressed in units of ppm. Data processing was carried out using Excel and SAS 9 software. The results showed that there were differences in the growth and production components between the local Timor and East Timor upland rice cultivars. Cultivars with cultivar V2 (muit fua naek) productivity as seen from the t/ha yield of 3.20 tons per ha were significantly higher than the other cultivars. The results of the analysis of Fe and Zn content showed that cultivar V6 (Aen Mael) had the highest Fe content of 15.1 among the other cultivars, and the lowest was cultivar V4 (Aen Ek ELo) which had an Fe content of 13.0. The highest Zn content was in cultivar V5 (Aen Muit Fua Ana) with a Zn content of 27.9 while the lowest was in cultivar V2 (Muit Fua Naek) with a Zn content of 20.4.
