Abstract

The biopore infiltration hole with organic material litter can increase the soil capacity to accommodate and store soil moisture. This study was aimed to determine the effect of biopores and organic material litter on soil moisture storage and the relationship of climatic conditions on soil moisture storage. The experiment was carried out on clove plantations on Ternate Island, North Maluku from December 2018 to February 2019. This study used a factorial randomized block design. The first factor was the biopores with a depth of 50 cm and 90 cm, and the second factor was 4 types of organic material litters in the form of nutmeg leaves, clove leaves, Guinea grass leaves and a mixture of clove leaves and Guinea grass. The factors observed were total soil water storage and at depths of 0-20, 20-40, 40-60 and 60-80 cm; organic matter content; C/N ratio and soil total N. Data analysis used the GenStat program with analysis of variance test (ANOVA) and Duncan's Multiple Distance Test. Results of the study showed that evaporation and percolation are climatic factors that affect water loss. Increase in soil water storage at 20-40 cm soil depth of 107.56 mm was yielded by the treatment of 50 cm biopore and Guinea grass leaf litter but it was not significantly different from the 50 cm biopore and clove leaf litter + chicken manure treatment. The treatment of biopore and organic material litter also increased the organic matter and soil total N and decreased the soil C/N ratio, but it did not have a significant effect.

Abstract

Rootstock affects the success rate of vegetative compatibility through the grafting method. Knowing one of the best rootstock ages that determine the percentage rate of success of the grafting method is the goal of this study. The method used was a randomized block design with 3 treatments for rootstock age 60 days, 90 days, and 120 days. The results showed that the difference in rootstock age affected 90% of the success of vegetative propagation using the connection method on the emergence of new shoots and the number of leaves. The highest percentage of success was in the treatment of rootstock seedlings aged 60 days (48.75%). The highest number of leaves was in the treatment of nutmeg seedling age of 60 days (6 pieces) while the lowest was in the treatment of 120 days (3 pieces).

Abstract

Dryland farming is one of the main agricultural models farmers use on the islands of North Maluku, so it is very dependent on the availability of rainwater. The water for crops is available in the rainy season, and drought is experienced in the dry season, one of which occurs on Hiri Island. This study aimed to analyze the availability and water needs of plants based on land characteristics and use to provide information for the development of dryland farming on Hiri Island. The method for calculating water availability used the land water balance approach using rainfall data for the last ten years, while the analysis of plant water needs was based on the soil moisture content and plant coefficient approach. The results of the analysis of water availability based on the land water balance of 2,236.4 mm with an average monthly rainfall of 186.4 mm and according to the type of land use on Hiri Island show that the highest available water in agroforestry was 40.92% in the secondary forest was 39.04%, in coconut, plantations was 35.72%, in fields was 35.18%, and undergrowth was 34.67%. Plant cultivation businesses must meet the water needs of plants to increase production. The people on Hiri Island need 29,340 L of water to fulfill their daily needs.

Abstract

Organic materials refer to substances derived from plant or animal waste and by-products, including manure, composted rice straw, plant residues, sewage, green manure, legume cuttings, and municipal or industrial waste (Zaini et al., 2004, cited in Pirngadi, 2008). This study aims to assess the level of organic material availability and identify the factors influencing it. The parameters analyzed include soil pH, total nitrogen (Total-N), organic carbon (C-organic), organic materials, water content, and the C/N ratio. The research was conducted in Subaim, Bumi Restu Village, in the Wasile District of East Halmahera Regency.The calculation of organic material values involved multiplying the C-organic content by a factor of 1.74%. The findings reveal that the average organic material content across various types of rice field land uses ranges from moderate to high, specifically between 4.12% and 4.43%. The higher levels of organic materials are attributed to the application of rice straw and organic fertilizers during post-harvest and land preparation phases. Conversely, lower organic material values are primarily due to the significant consumption of organic matter by plants during their growth stages

Abstract

Appropriate land management has a long-term impact on soil performance and is believed to improve soil fertility. This study investigated the effect of eco-enzymes on soil nutrients and plant productivity of green mustard-peanut in inceptisol. The research was conducted from February to April 2025.  The experiment used a randomized block design (RBD) consisting of 5 treatments and replicated 3 times, so that there were 15 units, including N0 = without Eco-enzyme, N1 = Eco-enzyme 2cc/L. N2= Eco-enzyme 4cc/L, N3= Eco-enzyme 6cc/L, and N4= Eco-enzyme 8cc/L. The commodities used were green mustard (Brassica juncea L) and peanut (Arachis hypogaea Linn). Soil properties variables included soil pH, N-total, and P-available, while plant productivity variables included plant height, number of leaves, leaf area, fresh weight, and pod production. The results showed that the concentration of eco-enzymes had a significant effect on N-total, P-available, green mustard plant height, and peanut plant height. However, eco-enzyme concentration had no significant effect on soil pH, number of green mustard leaves, green mustard fresh weight, green mustard leaf area, number of peanut branches, and peanut pod production. The lowest production of green mustard was 0.85 tons/ha, and the highest was 3.29 tons/ha. While the lowest production of Peanut pods was 4.3 tons/ha and the highest was 6.67 tons/ha.
