Abstract

The research aims was to know land condition of dusung sago around the river riparian area or at least 10 meters from the right and/or left of the riverbank. The method used was a survey with free survey observation distance approach. The observation was conducted intensively on sample area of dusung sago located around 10 meters from the riverbank. The result showed that the soils found in the research area are alluvial and regosol soils according to the National Soil Classification (2014), and their formation are influenced by very poor to poor hydrological condition as indicated by very shallow average groundwater at < 20 cm below ground level. The existence of sago plants in the Wai Poka riparian area is endangered by the expansion of settlements in the Poka area.

Abstract

One of the agricultural commodities in Indonesia which is a source of foreign exchange for the country is nutmeg. The nutmeg plant is a plant whose all parts can be widely utilized both on an industrial scale and to meet community needs. The yield of nutmeg is an export commodity that is very important for increasing the country's foreign exchange, but the lack of proper cultivation techniques, especially maintenance, results in the process of growth and production of nutmeg plants often experiencing disturbances. In addition there are also disturbances that come from wild plants called weeds. Weeds grow side by side with nutmeg plants, thereby disrupting the growth process of nutmeg plants and reducing nutmeg production. One of the causes of the decrease in nutmeg production in every planting area in Negeri Hatu, Central Maluku Regency, is weeds. Weeds are present in every nutmeg plantation area. The hypothesis put forward in this study is that there are various types of weeds, there are dominant weeds in the planting area, there are suggestions for proper weed control. This study uses the "vegetation survey" method to collect data with field observations. In carrying out the vegetation analysis, the quadratic method was used with sample plots measuring 1 m x 1 m, on 6 nutmeg trees and on each nutmeg tree 3 weed samples were taken so that a total of 18 weed samples were taken under the nutmeg plant canopy Quantitative data / primary data includes density , frequency and biomass. Observation of weeds was carried out destructively, namely the types of weeds in the sample plots were removed to calculate the individual and the biomass of each type.Keywords: vegetation analysis, dominant weeds, nutmeg

Abstract

A cropping pattern is an agricultural management activity that takes climate and soil conditions into account and seeks to achieve maximum results. Controlling cropping patterns is part of agricultural action planning to minimize the risk of crop failure. The purpose of this study is to (i) describe the climatic conditions in the Taniwell area, (ii) establish an effective growing season in the Taniwell area, and (iii) determine planting patterns for food crops in the Taniwell area. That's it. Length of growing season available. This study used his monthly climate data for 30 observation years from 1992 to 2021 from the Namlea Meteorological Station. Data analysis by following steps: (i) Analysis of rainfall (ii) Calculation of average rainfall (iii) Determination of rainfall with 75% probability (iv) Determination of planting season and planting pattern. The results showed that the effective growing season in the Taniwell area lasted 6 months and 24 days. It starts on December 1st and ends on June 24th.

Abstract

The growth of mustard plants is influenced by the availability of nutrients through the application of fertilizers. Manure and sea mud are one type of biological fertilizer. The study aims to determine the optimal dose of sea mud and manure for the growth and production of mustard plants. The study design was a randomized group design consisting of 2 factors and repeated 3 times. The first of Sea Mud treatment (L) consists of levels, namely: L0 = Control; L1=500 g, L2= 750 g. L3 1000 g. The second factor is that the dose of manure consists of levels, namely: P0=without manure; P1=120 g, P2=160 g: and P3 = 200g. The results showed that L3 treatment was able to increase plant height, while the number of leaves was best in L2 treatment. This treatment was also able to increase the number of leaves, fresh weight and dry weight but between L2 and L3 treatments did not differ markedly. P3 manure treatment is able to increase the best number of leaves, while fresh weight is best P2 treatment. The interaction between treatments only occurred in plant height and leaf area parameters at 17 HST observations.

Abstract

The objective of this study was to optimize the productivity of nutmeg (Myristica fragrans Houtt) through the application of concentration levels and frequency of liquid organic-inorganic mixed plant nutrition was carried out in the Nutmeg Garden of Hative Besar Village, Ambon Island, using a factorial complete randomized block design 3 x 2 + 1 (control, without treatment). The first factor consisted of three concentration levels, namely 1500 ppm, 3000 ppm, and 4500 ppm. The second factor consisted of two application frequencies: every two weeks and every four weeks. The sample employed in this study had an average age of 25 years. Each treatment combination was repeated three times with the total sampled 21 trees. The following yield parameter components were observed in this study: number of harvested fruits, fresh fruit weight, wet seed weight, dry seed weight, and dry mace weight. The results showed an interaction between the combination treatment of liquid organic-inorganic mixed plant nutrient concentrations and the frequency of application to the variables of fresh fruit weight, wet seed weight, dry seed weight, and dry mace weight. The variable number of fruits harvested per plant did not show an interaction effect between the concentration level and the frequency of giving liquid organic-inorganic mixed plant nutrition. Still, the best average number of fruits harvested per plant was found in the combination treatment between a concentration of 3000 ppm and a frequency of application every two weeks. The application of liquid organic-inorganic mixed plant nutrition with a concentration of 3000 ppm with a frequency of application every two weeks showed a positive response to increasing plant productivity when compared to other treatments or without the application of plant nutrients.

Abstract

One of the main pests and many damaging rice plants is gold snails. The damage caused can reach 13.2–96.5%. This pest is difficult to control despite the application of pesticides. The purpose of the study was to determine the effect of organic pesticide-producing plants on the mortality of gold snail pests in rice fields. The experiment using Complete Randomized Design consisted of 5 treatments, namely: P0 (control), P1 (tubal root extract), P2 (soursop leaf extract), P3 (lemongrass extract), P4 (papaya leaf extract) and P5 (jatropha leaf extract). The results showed that the highest average consumption rate was found at P1 (70.73%) and the lowest at P0 (1.73%). The highest average mortality rate from this pest was found at P1 (80) and lowest at P0 (0) during the observation period 4 hours after application. While at 8-hour observations the average mortality was highest at P4 and P5 (60) and lowest at P0 (13) after application. The highest average death time velocity was observed at P1 (3) and lowest at P0 (0) in the observation period 4 hours after application, while the highest average death time speed 8 hours after application was found at P4 and P5 (5) and lowest at P0 (2).
