  Abstract: Oil palm (Elaeis guineensis Jack) is an important plantation commodity for both agriculture and the economy, because its oil-producing potential is greater than that of other crops, such as corn, soybean and sunflower oil. The main disease of this plant is stem rot (BPB) caused by Ganoderma boninense. Therefore, it is necessary to know the incidence and severity of the disease as well as the control efforts that have been carried out at PTPN VIII Palm Oil Plantation, Cikasungka. The study used a Randomized Block Design with 3 observation blocks that had Ganoderma boninense attack each covering an area of 25 ha, each block taken 5 observation plots with an area of 50 x 50 m2 each (4 on the edge of the block and 1 in the middle of the block), then from each plot, 5 sub-plots measuring 10 x 10 m2 were taken (4 at the edges of the plot and 1 in the middle of the plot). Observational data were analyzed with variance and further tested by Duncan Multiple Range Test. The results of this study indicate that the symptoms of disease in the garden are very diverse, ranging from mild to very severe. The signs of the disease can be identified through the fruiting bodies of Ganoderma boninense. The incidence of disease in all survey locations ranged from 16 – 38%, where B3 was significantly different from B1. The lowest percentage of disease severity was in location B3 (5.75%) which was statistically significantly different from location B1. Location B1 had the highest disease severity, which was 23%. The control of BPB that has been carried out at the survey site includes the construction of isolation trenches followed by the application of biofungicides with the active ingredients of T. koningii and T. harzianum.

  Abstract: The demand for mustard consumption continues to increase, which encourages an increase in mustard production which is not proportional to the area of agricultural land so that cultivation with an NFT Hydroponic system is needed with the application of a magnetic field as a solution to this problem. Which the magnetic field can accelerate growth and water absorbtion. The purp ose of this study was to determine the interaction of magnetic field application with varieties on the growth and yield of mustard using the NFT hydroponic system. This experiment used a split-plot design consisting of 2 factors and 3 replications. The magnetic field application as the main plot consisted of 2 levels, without magnetic field application (M0) and magnetic field application (M1), while the varieties as sub-plots consisted of 5 levels, Tosakan (V1), Shinta (V2), Dakota (V3), IRR(V4) and Nauli F1 (V5). The observation variables were plant height, number of leaves, fresh weight, dry weight, and root volume. The results showed, there was a significant interaction only on the number of leaves with the best treatment M1V5 (16 number of leaves). The magnetic field factor significantly affected all growth and production variables of mustard except dry weight.

  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.
