Abstract

Management of peat soil for pineapple cultivation in Kualu Pineapple Village is still very traditional. In planting not using spacing, fertilization only uses fertilizers containing N, namely urea. In addition, there are differences in principles in managing peat, namely that there are farmers who add ameliorant ingredients and some do not. The purpose of this study was to determine the chemical properties of the soil, and nutrient uptake of pineapple plants in Kualu Nenas Village where the soil was given dolomite lime ameliorant and without ameliorant. This research method uses qualitative (survey) and quantitative (laboratory analysis) methods. A sampling of plants whose soil was given dolomite lime ameliorant and soil without ameliorant was carried out by purposive sampling technique. The research data were analyzed by a T-test to determine the difference between the chemical properties and nutrient uptake of pineapple plants. The T-test was analyzed using the SAS program (SAS User Manual Version 9, 2004). The results of this study were that the soil PH, P-available, K-dd, Ca-dd, Mg-dd, CEC, and base saturation content in pineapple plantations where the soil was treated with dolomite lime ameliorant had a significantly higher value based on the T-test compared to pineapple plantations with no ameliorant. Nutrient uptake of N, P, K, Ca, and Mg in pineapple leaves was not significantly different between plants whose soil was treated with dolomite lime ameliorant and those without ameliorant.

Abstract

ABSTRACT The purpose of this study is to determine the effect of interaction and the main influence of vermicompost and NPK Pearl 16:16:16 on the growth and yield of celery plants. This research was carried out for four months, from August to November 2018. This research used a factorial completely randomized design (RAL) consisting of two factors, where the first factor was vermicompost fertilizer (K) consisting of 4 levels, namely 0, 60, 80, 100 g / polybag and the second factor is NPK Pearl 16:16:16 (N) fertilizer consisting of 4 levels, 0, 0.8, 1.6, 2.4 g/polybag. The observation parameters in this study were plant height (cm), relative growth rate (g), root volume (cm3), number of tillers, number of midribs, wet weight of crop (g), and age of harvest (days). The last observation data were statistically analyzed and continued with a BNJ follow-up test at the 5% level. The results showed that the interaction between vermicompost and NPK Pearl 16:16:16 fertilizer significantly affected plant height from week two to week seven, the relative growth rate in the first week, root volume, number of tillers, number of fronds and wet weight per plant. The best treatment is K3N3 (K3 vermicompost fertilizer = 100 g /polybag and NPK Pearl 16:16:16 N3 = 2,4 g/polybag), but it has no significant effect on the age of harvest and the main effect of vermicompost and NPK Pearl 16:16: 16 significantly affected plant height, relative growth rate, root volume, number of tillers, number of midribs and wet weight of the crop, with the best treatment being K3 (vermicompost fertilizer 100 g/polybag) and N3 (NPK Pearl 16:16:16 2,4 g/polybag).

Abstract

The aim of this study was to determine the effect of administering a fungicide with the active ingredient propined and the time of application on the growth of Fusarium oxysporum in vitro. The design used in this study was a factorial Completely Randomized Design (CRD) using two factors, the first factor was the dose of fungicide which consisted of 3 levels (F), namely: 700 ppm, 1700 g/l water, and 2.7 g/l water. and the second factor was the time of inoculation which consisted of three levels so that there were 9 treatment combinations with 3 replications, so there were 27 experimental units. Each experimental unit consisted of 2 Petri dish plates which were inoculated and sampled so that there were 54 Petri dish plates. Parameters observed were the effective day of colony formation, colony diameter, conidia length of Fusarium oxysporum, inhibition of growth of Fusarium oxysporum, and macroscopic and microscopic identification of Fusarium oxysporum. If the calculated F is greater than the F table, then the BNJ test is continued at the 5% level. Based on the results of the study, the following can be concluded: treatment interaction with propined concentration and application time affects all observation parameters, where the best treatment is propined concentration of 2700 ppm and concurrent application of propined (F3S2). The main effect of real propined concentration on all observation parameters, the best treatment was propined concentration of 2700 ppm (F3). The main effect of actual application time on all observational parameters, the best treatment was with a propined application (S2).

Abstract

The purpose of this study was to determine the effect of the interaction of various organic composts and banana peel POCs on the growth and production of red ginger (Zingiber officinale var Rubrum). This study used a Factorial Completely Randomized Design (CRD), which consisted of two factors and 3 replications. The first factor was various organic compost (P), consisting of 4 levels, namely 0.600 (Vegetable Compost), 600 (Ketapang Compost), 600 (Straw Compost) g/plant and the second factor was banana peel organic fertilizer which consisted of 4 levels, namely 0, 125, 250, and 375 ml/L of water. Parameters observed were plant height (cm), number of tillers (stem), the weight of wet safe (g), wet weight of rhizome (g), dry weight of rhizome (g), and harvest index (g). The data were statistically analyzed and continued to the BNJ test at the 5% level. The results showed that the interaction of various organic compost and banana peel POC treatments affected the number of clumps of tillers (stems), wet rhizome weight (g), wet rhizome weight (g), and dry rhizome weight (g). The best treatment was found on a combination of 600 g/Plot Straw Compost and Banana Peel POC with a dose of 375 ml/L water. The main effect of various organic composts affects all parameters of the observation with the best treatment was the 600 g/plant Ketapang Compost. The main effect of POC Banana Peel affected the observation parameters Wet rhizome Weight (grams), Wet Rhizome Weight (grams), Dry Rhizome Weight (grams), and Harvest Index. The best dose for POC Banana Peel Treatment ws 375 ml/L water.

Abstract

This study aims to determine the effectiveness of several concentrations of cinnamon essential oil to control stem canker disease in dragon fruit caused by the fungus Neocytalidium dimidiatum. This research was conducted at the Laboratory of Pests and Diseases. Research Institute for Tropical Fruit Plants (Balitbu Tropika), Aripan, KM 8, X Koto Singkarak District, Solok Regency, West Sumatra. This research was conducted for 3 months, starting in April 2021 and ending in June 2021. In this study, using a non-factorial, completely randomized design with 5 treatments of cinnamon essential oil with 5 repetitions, each consisting of 4 petridish units, 100 experimental units were obtained. The treatment factors were 0.05%, 0.1%, 0.15%, and 0.20% cinnamon essential oil. The data from this observation were analyzed statistically. If the F count was greater than the F table, then proceed with the DMRT test. Based on the results of the study, it can be concluded that the growth of the fungus Neocitalidium dimidiatum is effective against cinnamon oil, having a significant effect on all observed parameters. The best treatment was cinnamon essential oil with a concentration of 0.20%.
