Abstract

The application of urea and cow manure on ultisol soil for mustard greens (Brassica Juncea L) aims to determine the treatment of cattle fertilizer on increasing leaf area, root volume and plant fresh weight. as well as the interaction of giving oxen fertilizer (t/ha) and urea fertilizer to mustard greens. This research was conducted in N4 Village with a height of 18 meters above sea level in Labuhanbatu Regency from December 2020 to March 2021. The study will be conducted with a factorial group design. The first factor is the provision of factorial Randomized Block Design (RAK) which consists of 2 factors, the first factor is Ox manure (K) which consists of 3 levels and the second factor is the provision of Urea fertilizer which consists of 2 dose levels, so that 6 treatment combinations are obtained. - 4 replicates each, resulting in 24 plots. Each plot consisted of 25 plants and 5 plants were taken as samples. Parameters observed were plant height (cm), number of leaves (strands), leaf area (cm2), root volume (ml) and plant fresh weight (g). The data obtained from the results of the study were statistically analyzed by means of variance and continued with the Duncan's New Multiple Range Test (DNMRT) at a level of 5%. The results of the study. urea dose of 100 kg/ha was able to produce an increase in leaf area, root volume and plant fresh weight. As well as the interaction of the application of ox-fertilizer (t/ha) and urea fertilizer gave a significant effect on the parameters of leaf area, root volume and plant fresh weight.

Abstract

Utilization of land for other uses in Sigumpar District needs to be supported by information regarding land suitability. Therefore, an evaluation of the characteristics of the level of land suitability in the area was carried out, to analyze improvement efforts aimed at increasing productivity, as well as to create a map of actual land suitability and potential land suitability for durian plants in the district. The method used is the survey method. Land units are based on soil maps, slope maps, altitude maps, land cover maps, consisting of 6 land units and 18 points. The analysis method is the comparing (matching) method. The results of the research show that the level of land suitability for durian plants (Durio zibethinus Murr.) The actual land conditions suitable for durian cultivation in Sigumpar District are 1,856.22 ha. (2) Potential land conditions suitable for durian cultivation in Sigumpar District are 1,726.22 ha. Where limiting factors that cannot be remedied are temperature and soil texture, while limiting factors such as nutrient retention, nutrient availability, water availability and erosion hazards can be remedied in the form of: (1). Liming and fertilization adjusted to the results of soil tests on the land. Making drainage channels, planting parallel to contours, and making terraces. Keywords: land suitability evaluation, durian plant, utilizzation of other area, subdistrict of Sigumpar

Abstract

Rubber plants (Hevea brasiliensis) will experience a decrease in production as plants age and the nutrient content in the soil decreases. This study aims to find out the chemical properties of soil on plantations of rubber crops that are converted into palm and coconut crops. The research was conducted from Februari 2023 to Agustus 2024 at the palm coconut plantation of PTPN III Aek Nabara North Garden in Labuhanbatu district and analyzed in the Land Laboratory of the Faculty of Agriculture of the University of Northern Sumatra. The methods used are observation methods, field sampling, and analysis in the laboratory to obtain quantitative data. Observation parameters include soil pH, C-organic, Total Nitrogen, Available P, Cation Interchange Capacity, and Base Fulness. The results of the survey showed that the level of soil fertility at the site of the research was included in the low category. The main limiting factor that causes the low fertility of the soil is the low content of organic material in the soil. In order to improve the fertility status of the ground at the research site for further planting, it is necessary to make efforts such as irrigation and fertilization, as well as the addition of organic materials, to make the availability of nutrients for plants more affordable. Keywords: replanting area, rubber plants, conversion, soil fertility, quantitative data
