Abstract

The Kali Kungkuk micro watershed which is located in the upper area of Brantas watershed, had  experienced forest conversion to horticulture during the last fourth decades. Since the physiographic of Kali Kungkuk micro watershed is hilly, forest conversion to horticulture may result in soil nutrient stock changes. The research aimed to analyze soil nutrient stock from forest to horticulture land uses (i.e. apple orchard and vegetables) in the Kali Kungkuk micro watershed. The field research was conducted on three different land uses (i.e. vegetable land (PK), apple orchard (PA), and forest (PH)) and four land slope classes (i.e. slope 0-8% (K1), 8-15% (K2), 15-25% (K3), and > 25% (K4)), with three, replicates plots of each. Soil samples were collected at three different depths (0-10, 10-30, and 30- 50 cm) from each plot. The parameters measured included soil texture, bulk density, standing litter mass, canopy cover, basal area, soil organic carbon and total  nitrogen. Data analysis was conducted with Linear Mixed Effect Models with a level of 5% and a further analysis of LSD test level of 5% as well as a correlation test between observational parameters. The results showed that differences in land use and slope affected to significant differences in the content of soil organic C and total N. In general, forests had higher soil C and N stocks as compared to other land uses (i.e. apple orchard and vegetables). Furthermore, soil organic C and total N was higher in the low slopes (i.e. 0-8%) and (8-15%) as compared to the high slopes (i.e. 15-25%) and (> 25%). The study found a positive correlation between soil nutrient stocks (i.e. C and N) and clay content. In contrast, soil C and N stock was negatively correlated with soil bulk density. Soil fertility degradation that occurs in the Kali Kungkuk micro watershed (i.e. apple orchard and vegetables) requires serious attention in soil management in order to ensure the sustainability of apple and vegetable production.

Abstract

Climate change in coffee cultivation is very influential and can disrupt the hydrological cycle, so shade planting is required. Planting vegetation on coffee fields can affect the infiltration rate. The infiltration rate is the amount of water per unit time that enters the soil surface. The purpose of this study was to determine the infiltration rate with various shading, namely mixed shade (sengon, teak, pepper, and coconut), sengon shade, and monoculture coffee land and to determine the relationship between soil physical properties and infiltration rate on people's land. The measurement of the infiltration rate was done with a double ring infiltrometer and the Horton model. Infiltration rate can be influenced by a variety of soil properties such as bulk density, soil pore distribution, soil aggregate stability, soil texture, soil organic matter content, and land use. The analysis used correlation, linear regression, multiple linear regression, and t-test. Differences in shade and soil properties affect the infiltration rate, especially micropores and soil porosity. Soil with a lot of micro-pore soil, low porosity and clay texture has a slow infiltration rate. The results of the t-test between the actual infiltration rate and the infiltration rate of the Horton model showed no significant difference; therefore,  the Horton method approach can be used in estimating the actual infiltration rate in coffee fields.

Abstract

Landuse change causes the decrease of soil quality, so the hydrological and non-hydrological functions do not run optimally. Sisim Micro Watershed‘s area of ± 933.17 ha with a very steep slope has undergone major land-use changes. Soil Quality Index (SQI) analysis and water quality bioindicators are needed to assess the impact of land-use change. This study used 12 soil sampling plots, i.e. production forest (H2, H3, H4, H5), mixed gardens (KC2, KC3, KC4, KC5), and fields (T2, T3, T4, T5). The numbers behind the code indicate slope; 2 (slope 8-15%), 3 (slope 15-25%), 4 (slope 25-40%), and 5 (slope 40-60%). The results showed that dense vegetation and low intensity of tillage gave the best SQI. The highest SQI value was on H5 (0.63) with a good category, and the lowest was on T5 (0.32) with a bad category. The water quality bioindicator showed water pollution index of 1.97 (dirty water quality and rather heavily polluted). Soil quality which is dominated by low categories with high agricultural intensity and community waste disposal causes health condition of biotic habitats classified as unhealthy with a score of 1.90.

Abstract

Fruit plants in Kediri Regency are classified as having good economic potential, one of which is pineapple. Pineapple plants in Kediri Regency have differences in productivity in each sub-district. The results of interviews with local farmers indicated that the Supiturung Micro Watersheds in Plosoklaten District had low pineapple productivity and were not yet optimal. Therefore, this study aimed to determine the factors causing differences and less optimal productivity of pineapples in the Supiturung Micro Watersheds and analyze the land suitability assessment of pineapple plants in the region. This study used a survey method with a physiographic approach to 10 Land Map Units (LMU) and determined 20 observation points as representatives. Data analysis was performed through correlation and multiple regression tests with the stepwise method to determine the land characteristics that most significantly affected pineapple productivity. Modification of the suitability class and modification of the criteria was carried out utilizing boundary line analysis, with class boundaries according to FAO (1976), namely class S1 (80-100%), S2 (60-80%), S3 (40-60%), and N (<40%) of the potential productivity. The land suitability evaluation results of pineapple plants in the Supiturung Micro Watersheds were included in land suitability classes S2, S3, and N. Based on the stepwise method analysis, the texture is a significant characteristic affecting the productivity of pineapples (p <0.05) with a correlation coefficient value of 0.838. The modification of land suitability criteria with boundary line analysis resulted in changes in one land characteristic, namely soil texture S2, S3, and N. Initially, the rough class included in the N class was changed to S2 level along with the slightly rough level.

Abstract

The current climate change has an impact on crop production, especially coffee plants. Rainfall is one of the climate elements that influences the process of crop cultivation, because of its role in the availability of water crops. Raindrops that fall on the vegetated land cover does not directly reach to ground, but will temporarily be accommodated by a canopy, stems and plant branch. Once those places saturated with water, the raindrops will drop to the soil surface through the canopy, stem flow and partially evaporated back into the atmosphere that called interception. The study aims to determine the effect of the shade of coffee plants on the interception, and stemflow of plant canopy. As well as knowing the relationship between rainfall with throughfall, stemflow, and interception. This research was conducted at smallholder coffee plantation in Sumbermanjing Wetan District on the use of gamal shade coffee grown, sengon shade coffee grown, and sun-grown coffee. The results showed that the value of canopy throughfall in the three land uses was not statistically significantly different, but there was a tendency for monoculture coffee plants which has a greater yield that is 66,38% of the total rainfall of 15,32 mm. The highest stemflow value is in the sengon shade coffee grown of 3,07% of the total rainfall of 15,32 mm. Interception in the gamal shade coffee grown is the highest compared to other land uses that results obtained are 36,92% of the total rainfall of 17,1 mm. Rainfall has a relationship with the value of stemflow, throughfall and interception. Based on the correlation analysis test the results were significantly correlated with strong relationship.

Abstract

PT. Great Giant Pineapple (PT. GGP) is the largest pineapple plantation company in Indonesia, with a land area of approximately ±33,000 ha and dominated by soil types in the form of Ultisols. Soil fertility at PT. GGP tends to have relatively low nutrient content, one of which is phosphorus due to Al fixation. The nutrient P in pineapple is used to stimulate root growth, accelerate the ripening of fruit and seeds. Symptoms arising from P deficiency will experience stunted growth (stunted), and the pineapple will become imperfect. This study aimed to estimate the P nutrient content in pineapple plants using vegetation indexes in the form of GNDVI (Green Normalized Difference Vegetation Index). The study was carried out by taking aerial photographs and samples of pineapple plants in the 1 months phase before forcing and 1 months after forcing (F-1 and F+1), laboratory analysis, statistical analysis, and making distribution maps. The results showed that the vegetation index could estimate the nutrient content of P using the best estimation model. This was evidenced from the results of the correlation test which shows a very strong and real relationship of 0.81-0.82 with the regression test results of 66%-67%. In addition, the results of the validation test using the paired t-test showed that the t-count was smaller than the t-table of 2.30, which means that the estimated GNDVI vegetation index and the P nutrient content of pineapple plants showed no significant difference.

Abstract

Garlic (Allium sativum L.) is a plant that is often used by Indonesian people in various ways. One of the reasons for the low productivity of garlic in Indonesia is the insufficient use of superior varieties and low S elements in the soil. Furthermore, the use of the number of cloves planted per planting hole will determine the number of populations so that it will affect the growth and production of garlic. The aim of this study was to analyze the effect of S fertilizer and the number of cloves on the growth and production of garlic (Allium sativum L.) and also analysis S residue from S fertilizer and number of cloves. This study used a randomized block design with nine treatment combinations, three levels of sulfur fertilizer doses (0 kg S ha-1, 140 kg S ha-1 and 200 kg S ha-1) and the number of cloves (1 clove, 2 cloves and 3 cloves). The results showed that the application of sulfur fertilizer and the number of cloves had no significant effect on growth parameters (plant height and number of leaves) in garlic plants. However, it significantly increased the diameter of bulbs, fresh bulbs weight and dry bulbs weight respectively by 13.39%, 140.72% and 93.64% to 24.29 mm, 5.97 g plant-1 and 4.57 g plant-1 in the treatment of one number of clove and 140 kg of S ha-1 compared to the treatment of one clove and without S. As well as significant effect on SO42- residues and total S with the highest yield respectively  299.3 ppm and 910 ppm and the lowest yield was obtained in the treatment without S fertilizer.

Abstract

The presence of mycorrhizae can reduce the level of poisoning caused by heavy metals in post-mining land and support plant growth. Post-mining land is generally only a few types of mycorrhizae that can adapt, especially post-mining land. This research was conducted to determine the presence, types and distribution of mycorrhizae as well as the relationship between soil depth and mycorrhizal distribution and soil chemical properties at various depths in the rhizosphere of bull grass as the dominant vegetation in post-coal mining land. The results showed that there were arbuscular mycorrhizae at each soil depth with different population density levels, namely 273 spores 100 g-1 soil at a depth of 0 - 10 cm (K10); 239 spores 100 g-1 soil at a depth of 10 – 20 cm (K20) and 155 spores 100 g-1 soil at a depth of 20 – 30 cm (K30). The arbuscular mycorrhizae found at all soil depths are of the same type, which is included in the genus Glomus. Soil depth with the number of arbuscular mycorrhizal distribution (r count -0.7754> r table -0.4973) has a very strong relationship and with soil pH (r count -0.6309> r table -0.4973) has a strong relationship. The number of distribution of arbuscular mycorrhizae with soil pH (r count 0.5943> r table 0.4973) has a strong relationship

Abstract

Land characteristics are factors that affect crop productivity. Different conditions of land characteristics will cause differences in crop productivity. Evaluation of land suitability can be used as a basis in assessing land quality to determine the factors of land characteristics that cause differences in crop productivity. The purpose of this study was to determine actual land suitability for cayenne pepper, determine which land characteristic affect crop productivity, and modify land suitability based on actual productivity suitability classes. This study was conducted in Wagir District, Malang Regency with a survey method on 8 Land Map Units (LMU) with 42 observation points. Quantitative parameters observed in this study include soil texture, pH, CEC, C-Organic, base saturation, N-total, P-available, exchangeable K, Ca, Mg, Na, and productivity of cayenne pepper in the field. Data analysis was performed by correlation test and multiple regression with the stepwise method. The results showed the actual land suitability class of cayenne pepper in the study area was S3 and N. Modifications to the characteristics of the land that most influence the productivity of cayenne pepper in the field, namely the pH of the soil produce new criteria with classes S1: 6.0-7.6; S2: 5,7–6,0; S3: 4,6-5,7; and N: <4,6. The land suitability assessment using the modified criteria resulted in the S3 conformity class, which was similar to the percentage productivity class and the N conformity class that was similar to the percentage productivity class.

Abstract

The increase in black soybean production is constrained by the decreasing productive land area due to increasing population pressure. Dryland is an alternative that can be developed because of its availability. This study aimed to determine the best dosage of biochar and NPK for black soybean plants in dryland. The treatments were arranged in a randomized block design with two factors that were repeated three times. The first factor was the dose of tobacco Jengkok biochar (0, 10, 15, and 20 t ha-1) and the second factor was the dose of NPK Phonska fertilizer (0, 25, 50, and 100 kg ha-1). Soil used for this study was collected from dry land in Gading Kulon Village, Dau District, Malang Regency. Ten kilograms of the collected soil was placed in a polybag and mixed with biochar according to the treatment dose. After 7 days of biochar application, soybean seeds of Detam 1 variety were planted, and soil samples were taken to observe soil organic C, N, P, and K contents. NPK fertilizer was applied according to the treatment dose at 10 days after planting, Plant height and number of leaves were observed at 2, 4, and 6 weeks after planting. Biomass and crop yields were observed at physiological maturity at 85 days after planting. The results showed that the highest levels of organic C, total N, and K were at a dose of 20 t biochar ha-1, but the use of 15 t biochar ha-1 was the optimum dose for biomass and yield of black soybeans. The highest seed weight was obtained from 100 kg NPK ha-1.
