Abstract

Alfisols is a soil that lack of organic matter (OM). thus making the physical properties of the soil is easily damaged, because OM is used as an adhesive on soil physical properties. This study aimed to examine the physical properties of  Alfisols in agroforestry based of teak and its effect on the development of soybean. This research used a Randomized Block Complete Design (RBDC) which consists of three factors (soybean varieties,  teak litter dose and NPK chemical fertilizers. The results showed that Alfisols in agroforestry based on teak relative good with the stability of the aggregate value of the 225,101 (Very Steady). Varieties and increasing teak litter doses affect soybean root development while NPK fertilizer did not make an impact. Argo Mulyo varieties have better root development in comparison with Grobogan, and litter dose of 2,5 Mg ha-1 has the best root development in each variety.

Abstract

Agriculture and irrigation policies in the tidal wetlands are often too general, thus at the level of farm units they are often inaccurate in term of quality and quantity. The research purpose was to analyze the groundwater levels and to determine the effect of groundwater levels in relation to some soil chemical characters in tidal wetlands P17-5S Mulyasari village Delta Telang II Banyuasin.  Indicators of potential land can be analyzed from parameters of variability of soil acidity, Al and Fe content, organic matter and phosphorus and nitrogen status of the soil. Managed limited area was the smallest unit of water management (tertiary plots). The decision was taken based on the dominant values of the hydro-physical and chemical characters. Input criteria design involved the nature of the soil, land use, and hydrology. The field study and analysis showed dominance in soil physical variability. Around 50% of hydraulic conductivity was classified rapid soil with soil acidity is relatively high, moderate nitrogen, low phosphorus, and moderate potassium. Based on these conditions, cropping pattern applied was rice-corn, rice-water melon, soil fertility can be improved through fertilization of N and P; increasing water gate in the tertiary plots, and the water management aimed to controlled drainage

Abstract

Banana stem water content is 90%. Therefore, it is potential as an alternative for planting media in limited agriculture lands due to their function changes. The aim of the research is to obtain information on cultivation technology and how long water content in banana stem is available for plant. This research employed the randomized block design- split plot with two treatment factors. The first factor was banana stem durations after harvest (0, 2, and four weeks) and the second one was vegetable crops, namely: kangkungs and mustard greens. Based on the treatment level, there were six combinations, and each was replicated 4 times. The research variables were height, number of leaves, chlorophyll content, nitrogen tissue, leaf area index, specific leaf area, unit price of leaves, growth rate, biomass (dry weight of the plant), length of root, and fresh weight of the plant. The result of the research shows that all treatments applied to banana stems had no effect on all variables tested. Banana stems could provide water to Ipomoea reptans Poir for the duration of 37 days after planting, and to mustards greens for the duration of 32 days after planting. Above the stated duration, the plant died due to water excess. Thus, banana stems had the potential to provide water for plants from planting to harvest, and the plants planted did not require additional watering.

Abstract

This research purposed to know the effect of biofertilizers, the effect of soil type, and the effect of interaction between biofertilizers and soil type on growth and yield arrowroot. This study uses a randomized block design with 2 factors, namely biofertilizers of biota max consisting of 2 levels and types of land consisting of 2 levels. Analysis of the data using Analysis of Variance and continued with Test of Least Significant Difference at the level 5%. The results of this study indicate that: 1) application of  biofertilizer is effect significantly   against  increased  in the number of leaves, number of tillers total, relative growth rate and net assimilation rate, the number of tubers per hill, tuber diameter, tuber length and weight of tuber per hill than without the application of biofertilizers, 2) arrowroot planting in soil grumosol significant effect against  increased crop height, number of tillers total, relative growth rate, leaf area index, and the number of tuber per hill than arrowroot planting in rendzina soil.

Abstract

Research to determine of formulation humic substance and Trichoderma sp to increase the production and growth of corn (Zea mays, L). This research was conducted by extracting humic substance with fractionation organic matter method from cattle manure organic material. Trichoderma sp grow on corn medium and harvested after reaching a density of 1015 cfu. Created this compound formulation with mixing humic substance and Trichoderma sp. Indicator plant with F1 sweet corn Jago varieties. Application used humic substance in range 8%, 16%, and 32% on the recommended use NPK fertilizer for corn, as well as control without humic substance. The result showed application use  8% humic substance most good for plant growth and harvest. Additionally, nutrient uptake NPK fertilizer efficiency is increased and more effective than control and use of the formulation 16% and 32% humic substance.
