Abstract

The supply of hydroponic nutrients needs to consider economic, practical and resource saving aspects. It is necessary to know the best composition and type of nutrients that can be used in a hydroponic system. The use of liquid organic fertilizers (POC) as an alternative to hydroponic nutrients, especially in the wick system, has already begun including widely available alternative fertilizers such as NPK + Gandasil and utilizing chicken feather waste that has been made in the form of fertilizer. This research is expected to provide an overview of the potential for alternative nutrient sources for hydroponic growing media by utilizing the available resources. The study was started from June to August 2020, using a single randomized block design (RBD) consisting of 5 (five) treatment levels, namely: K0 = AB mix (control) 50 ml / 10 L water, K10 = 10 g NPK + 5g Gandasil / 10L water. K11 = 1/2 dose of Abmix + ½ dose of NPK + Gandasil, K12 = ½ dose of NPK + Gandasil + 4800ml / POC of chicken feathers / 10L of water, K13 = 1/2 dose of Abmix + 4800ml / POC of chicken feathers / 10L of water. The results showed that the type of nutrient media composition had no significant effect on plant height in weeks 1,2,3 and 4, leaf length weeks 1 and 2 and number of leaves weeks 1,2,3 and 4. The type of nutrient media composition had a significant effect on leaf length weeks. 3rd and 4th week.The best treatment was obtained at K0. (Abmix), which was significantly different from k10 and k12 treatments, and not significantly different from all k11 and 13 treatments.At week 4, the best leaf length was also obtained at different k0 treatments. real with all other treatments. There is potential for alternative nutrient utilization, because it is able to approach growth using standard nutrients for variables of plant height and leaf number.

Abstract

The variation in soil permeability levels as a result of several types of land use on dry land in Aceh Besar district is not widely known. Therefore, a study of the ability of soil to pass water (soil permeability) as a result of various land use patterns is very important to conduct research in order to maintain a sustainable environment. The metode of research used is directly survey method. The Field survey carried out by taking soil samples that were taken in a composite manner in the processing layer (0-20 cm) and intact. The variables measured include: permeability, soil organic fraction. Intact soil sampling is carried out using a ring or tube to determine soil permeability based on the constan head method. Meanwhile, composite soil samples, which are samples collected from several observation points mixed evenly into a homogeneous sample, those were used to variable soil organic fraction content using the pipette method. Permeability in the type of land use forest shrubs, mixed gardens, moor and teak forests were classified into the medium class. The order of increasing permeability starts from the type of land use for forest shrubs, mixed gardens, moorlands, teak forests and rainfed rice fields. Permeability rates didn't have correlation with organic matter content in several types of dry land use in Aceh Besar district. By increasing sand content, the pores between particles increase, the capillary action weakens, and water easily evaporates through the macro pores, or directly penetrate deep into the soil for vegetation use By increasing clay content, the effect of soil on local rainfall redistribution on vegetation growth changes from decreasing to increasing whereas sand, on the other hand, those was based on a limited distribution of soil types only with high clay content

Abstract

Papaya propagation from seeds has a major problem, namely seed germination takes a relatively long time. Experiments to determine the effect of gibberellin and cow bio urine concentrations on the growth of papaya seedlings were carried out at the Main Horticultural Seed Center of the Agriculture and Livestock Service Office of Buleleng Regency with an altitude of ± 200 m above sea level. The experiment used a factorial randomized block design consisting of two factors, namely the concentration of gibberellin and the concentration of bovine bio urine. Application of gibberellin significantly affected plant height, root length, root wet weight, root oven-dry weight, leaf wet weight, leaf oven-dry weight, total fresh weight, and total oven-dry weight. Gibberellin with a concentration of 150 ppm gave the highest total fresh weight and oven-dry weight, namely 14.63 g and 1.44 g respectively compared to other treatments. The concentration of cow bio urine had a significant effect on root length, very significantly on plant height 40 DST and 47 dd, stem oven-dry weight, leaf wet weight, leaf oven-dry weight, total fresh weight, and total oven-dry weight. Biourine with a concentration of 200 ml.l-1 gave the highest yield in total oven-dry weight per plant, namely 1.19 g. The combination of the concentration of gibberellin and bovine bio urine significantly affected the root length of the plant.

Abstract

The production of organic spinach hasn’t been able to keep up with market demand, it is necessary to produce quantity and organic spinach. The research was carried out in the laboratory and greenhouse of the Agriculture Faculty, KH.A. Wahab Hasbullah University in February - May 2021. The purpose of this study was to aims to determine the effectiveness of giving mycorrhizae to spinach plants given various organic fertilizer compositions with the decomposer Trichoderma sp. The research design used was a completely randomized design, with five treatments and five replications. The treatments are; M0 (8 grams of mycorrhizae with 0% organic fertilizer as negative control), M1 (8 grams of mycorrhizae with 25% organic fertilizer), M2 (8 grams of mycorrhizae with 50% organic fertilizer), M3 (8 grams of mycorrhizae with fertilizer organic 75%), M4 (8 gr mycorrhizal with 5 grams of NPK fertilizer as positive control). The results are M2 treatment showed good growth in plant height (18.26 cm), the number of leaves (8.40 leaves), plant wet weight (3.65 gr), and root length (13.69 cm). Mycorrhizal spinach plants are effective in absorbing nutrients available in organic fertilizers 50% of the composition of the growing media, but less effective at 25%,75%, and NPK Mutiara 16:16:16 fertilizer. Organic fertilizers with local Trichoderma sp isolate decomposer are able to provide nutrients needed by spinach plants for their growth. The application of organic fertilizers with a composition of 50% to plants given mycorrhizae is possible to suppress the use of inorganic fertilizers.

Abstract

Weeds are unwanted wild plants because they can interfere with the main crop cultivation. This study aims to identify and analyze the diversity of weed vegetation that grows around mango trees. This study uses the quadratic method with diagonal observation points and direct exploration techniques. Observation parameters include the type of weed and its population. Then the results of the observations were analyzed using the formula of Important Value Index (INP), Summed Dominance Ratio (SDR), Diversity Index (H'), Index of Similarity (IS), and Dominance Index (C). After doing the research, found 24 species of weeds consisting of broadleaf weeds, puzzles and grasses. The highest SDR value in Tondowulan Village was Cynodon dactylon L. at 13.82%, while in Darurejo Village it was Oplismenus hirtellus (L.) P. Beauv. by 26.53%. Weed diversity was classified as moderate because the weed diversity index value in Darurejo Village was 1.92% while in Tondowulan Village it was 2.31%. The two research locations did not have the same composition of weeds because the similarity value was only 33.33%. There is no weed species that dominates the mango garden because the index value of the weed dominance in Tondowulan and Darurejo Villages in the order of the 3rd largest is less than one.

Abstract

This study aims to determine the effect of the pre-emergence application of the herbicide metsulfuron methyl on the soil mixed with rice husk biochar to the germination of weeds. This study used a factorial completely randomized design (CRD) with two levels of herbicide metsulfuron methyl (0 gr/ha and 300 gr/ha) and four levels of rice husk biochar (0%, 5%, 10%, and 15% of the total weight of the planting medium). The parameters observed were the number of weeds, wet weight of weeds, and dry weight of weeds. The results showed that the interaction of the herbicide metsulfuron methyl and rice husk biochar had no significant effect on weed germination. The single treatment of the herbicide metsulfuron methyl had a significant effect on the number of weeds, wet weight of weeds, and dry weight of weeds. Herbicides can reduce the number of germinated weeds, wet weight of weeds, and dry weight of weeds by 39.3%, 83.7%, and 84.7%, respectively. While the single treatment of rice husk biochar showed a significant effect on the number of weeds and dry weight of weeds. The 15% treatment of rice husk biochar was the best to reduce the number of germinated weeds, namely 76.6%. Rice husk charcoal has the potential to be an alternative to suppress weed seed germination in the soil without using herbicides.
