Abstract

Pakcoy cultivation in dry land is still not optimal due to the growing environment that requires technology. Fertigation verticulture is used as an effort to increase pakcoy production in dry land. The purpose of this study was to determine the fertigation time, composition of planting media and the distance between planting holes and their interactions in increasing nutrient uptake and efficiency of N and P absorption for pakcoy plants on the vertical fertigation system. This research was carried out in the agricultural garden of the Main Seed Center of the North Central Timor Regency Agriculture Office from June to December 2021. The study used an experimental method with a Separate Plot Design with 3 plots where the main plot was the fertigation time which consisted of 3 levels, namely W1 (60 seconds). ), W2 (90 seconds), and W3 (120 seconds). The main subplot is the composition of the growing media which consists of 4 levels, namely: M1 (Soil: Sand (1:1)); M2 (Soil: Biochar (1:1)); M3 (Soil: Biochar (1:1)); and M4 (Soil: Sand: Biochar (1:1:1)). The subplots are the spacing of the planting holes consisting of 3 levels, namely: J1 (15 cm); J2 (20 cm); and J3 (25 cm). There were 36 treatments which were repeated 4 (four) times in order to obtain a total of 144 treatments. Data analysis used a comparative test using the Duncan Multiple Range Test method at 5% level. The results showed that the fertigation time of 120 seconds (W3) and the composition of the growing media: biochar (1:1) (M2) and their interactions increased the N and P uptake of pakcoy plants grown in a verticulture system on dry land by treatment. The fermentation time of 120 seconds (W3) and the composition of the growing media: biochar (1:1) (M2) also increased the efficiency of N and P nutrient absorption.

Abstract

Utilization of Yard Land for Pakcoy Cultivation Verticulture System at KWT Mawar in Kuaken Village Timor Tengah Utara Regency. Mawar’s Woman Farmers Group (KWT) is located in Kuaken Village and has dry land with shallow and rocky solum. One of the businesses of KWT Mawar is cultivating vegetables. However, the land condition, which is quite dry and far from home, makes it difficult to cultivate crops, and they left her job as a housewife. The yard of Mawar’s KWT can be more productive for growing vegetables through the verticulture system. This service aims to utilize the yard as a pakcoy cultivation area with a vertical system using cow manure and biochar as a planting media at KWT Mawar, Kuaken Village. The activities were carried out in the KWT Mawar in June-August 2021. The activities consisted of several stages, namely: 1) verticulture pipe preparation, 2) planting media preparation, 3) seed sowing, 4) planting, and 5) harvesting. The result showed that the use of yardland through pakcoy cultivation with a vertical system provides many benefits for the community compared to cultivation in beds. This activity resulted in an average plant weight of 80.66 g/hole so total production of about 63 kg in 1 harvest was obtained. The productivity was 1.05 kg/paralon pipe. In addition, these activities have created food resiliences for the family, easier to carry out other activities as housewives, saved time and energy, can process rice husk and cow dung waste for a mixture of planting media, and made the yard have aesthetic value.

Abstract

Oil palm plantation expansion in Indonesia continue to increase year by year. Several varieties of oil palm have been produced but not much information about the growth characteristics. Urea as nitrogen fertilizer has become a staple for the cultivation cycle of oil palm. The determination of nitrogen use efficiency (NUE) on palm oil varieties can be used to find out N requirement of each plant according to their needs. This research was aimed to analyze the growth response and NUE of palm oil varieties to fertilizer N at pre nursery. It was conducted in nursery area at Yos Sudarso Binjai Street and Pusat Penelitian Kelapa Sawit, Medan from November 2016 until March 2017 using Completely Randomized Block Design followed by Scott Knott test at α = 5%. There were 35 treatment combinations that used seven varieties of Dura x Pisifera Medan Palm Oil Research Center (AVROS, Simalungun, PPKS 540, Yangambi, PPKS 718, PPKS 239, and Langkat) with N consisting of 5 levels (0 ; 0,5 g ; 1 g; 1.5 g and 2 g). The results showed that the application of N fertilizer influence significant effect on the growth of stem circumference and the number of leaves. The highest of nitrogen use efficiency is found in Simalungun varieties with N application of 1,5 g/plant.

Abstract

Mining activities are required to carry out reclamation. Reclamation efforts are aimed at restoring the condition of the mined land. The manganese mine in Kaubele Village has been carried out since 2011 but there has been no clear reclamation effort, causing the land to be abandoned. The study aimed to determine the vegetation and seed banks found on former manganese mining land in Kaubele Village, Biboki Moenleu District. This activity was carried out in July - December 2022 on former manganese mining land in 2010 and 2018. Vegetation was collected using a purposive sampling method. At each observation location, 5 main points were taken. Each point at each location is spread by 250 points with a 2 m x 2 m plot. The soil was taken at a depth of 0-20 cm and an area of 30 cm x 30 cm. Furthermore, it is placed in the nursery media for 3 months to find out the vegetation that grows. Vegetation and seed banks were analyzed based on species density, relative density, species frequency, relative frequency, and important value index. Vegetation analysis is a step in determining plants to restore ex-mining land. The vegetation in 2018 had more species compared to 2010. At both locations, there were the same 3 plants, namely Cynodon dactylon L. with an IVI of 21.421% (2010) and an IVI of 17.605% (2018), Chromolaena odorata L. with an IVI of 10.409% (2010) and IVI of 9.125% (2018), and Malvella leprosa (Ortega) krapov. with an IVI of 8.097% (2010) and an IVI of 7.031% (2018). Analysis of seed banks shows that there are 7 similar seeds found in different mining locations with respective IVI of Dactyloctenium aegyptium L. 78.550 % (2010) and 14.169 % (2018), Chloris virgata Trin 13.113 % (2010) and 8.986 % (2018), Panicum virgatum L. IVI 20.384 % (2010) and 46.834 (2017). (2018), Synedrella nodiflora L. IVI 22.068 % (2010) and 14.169 (2018), and Phyllanthus urinaria L. IVI 13.177 % (2010) and 12.957 % (2018).
