Abstract

The aim of this research is to know the effect of different manure types on the yield of wheat (Triticum aestivum L.) dewata 162 at different altitudes. The study used a factorial experiment arranged in a completely randomized block design with three replications. The first factor is the type of manure; cow, chicken, goat manure. The second factor is the difference in altitude; lowlands, midlands, and highlands. The results showed that the application of manure and different altitudes affected several parameters such as protein content, gluten content, and the weight of 1.000 dry beans. Chicken manure showed the highest dry weight of 1,000 seeds. The highest content of protein, gluten, and weight of 1,000 dry seeds are found in the lowlands.

Abstract

This study aims to determine the effect of the frequency of issuing Liquid Organic Fertilizer (LOF) and the concentration effect given singly and their combinations on the growth of wheat varieties Dewata 162. This research was conducted from April to June 2022, in Mejing Village, Candimulyo District, Magelang Regency with an altitude of ± 437 asl, regosol soil pH 6,3. The research method was a factorial experiment (3x4) arranged in a Completely Randomized Block Design (CRBD) with three replications as blocks. The first factor is the frequency of provisioning (every 9, 18, and 27 days). While, the second factor is the LOF concentration consisting of 0, 45, 90, and 135 ml/l. The result showed that the frequency of giving LOF every 18 days had a significant impact on the tillers' number. Giving LOF at intervals of once every nine days was exerted and showed extreme influence on the root number. Utilization of LOF once every 27 days influenced the root length. While LOF concentration did not affect all observation parameters. In addition, there was no interaction between the application frequency and concentration of LOF on wheat.

Abstract

Efforts to determine the presence and population of pests and natural enemies can be carried out through effective monitoring activities using certain traps. At the beginning of corn growth, plants are still susceptible to plant pests and disease organisms (OPT) on the soil surface. Therefore, pitfall can be used to monitor the insects. Research consisted of two treatments, the location of pitfall traps on the edge and middle of the cornfield. The research area measures 11 x 14 m with 24 pitfalls for each treatment. The pitfall trap was installed using a 220 mL plastic glass buried deep and filled with a detergent solution at a dose of 23 grams in 25 liters of water and left for 24 hours. All insects obtained and identified at the family level and their numbers populations. Data were analyzed using the T-Test. There are seven families whose role as pests are Acrididae, Gryllidae, Carabidae, Agromyzidae, Termitidae, Cicadellidae, and Blattidae. There are four families as natural enemies, namely Libellulidae, Lycosidae, Araneidae, and Formicidae. The percentage of pests and natural enemies on the edge of the field is 33.57% and 66.43%. In addition, the pest percentage in the middle of the cornfield is 28.69%, while natural enemies are 71.31%.

Abstract

This research aims to determine the effect of seed age and phosphate fertilizer dosage on rice yields. The research used a factorial Randomized Group Design (RAK) with two factors and three replications. The first factor is seed age (B) consisted of 4 levels, namely B1 = 15 HSS, B2 = 20 HSS, B3 = 25 HSS and B4 = 30 HSS, while the second factor is the use of phosphate -36 (P) with 3 levels, namely P1 = 50 kg/ha SP-36 equivalent to 5 grams/plot, P2 = 100 kg/hectare SP-36 equivalent to 10 grams/plot and P3 = 150 kg/ha SP-36 equivalent to 15 grams/plot. As a result, there are 12 treatment combinations were obtained. The results of the research showed that the B1 seedling age treatment (15 HSS) was significantly different and consistently obtained the highest results of number of tillers per hill (27), number of productive tillers (22.78), panicle length (24.58 cm). Meanwhile, the P3 Phosphate fertilizer treatment (150 kilograms/ha SP-36) was significantly different and consistently obtained the highest yield of number of productive tillers (21.75), flowering age (21.75 days), number of grains per panicle (166.08 grains), weight of grain per hill (78.78 grams), and weight of 1000 grains (4.01 grams).

Abstract

Dry land in Kalimantan has a potential area of 41.61 million ha or 29% of the area in Indonesia of around 144.47 million ha which can be developed for agriculture, plantations, and forestry. Dry land has the potential to be developed for annual crops such as fruit forest plants. Welcoming Kalimantan as the National Capital City (IKN), the development of agro-tourism and local fruit production in Kalimantan as a buffer zone for food security has national and international strategic and political values. Agro-tourism is prepared based on conservation and environmental preservation, especially local Kalimantan fruit. The steps needed to develop local Kalimantan fruit agro-tourism are determining land, making ponds, determining types of local fruit commodities, land and landscape arrangement, land preparation, selecting superior seeds, plant care, empowering local human resources, building facilities and infrastructure, promotion and partnerships, as well as the grand opening. There are several divisions of land in the Kalimantan local fruit agro-tourism area, on the mainland, namely local fruit preservation land, forest areas located on the outermost part of agro-tourism, determining the location of ponds as water sources, camping areas for visitors who want to stay overnight, as well as culinary areas. The dry land used will be planted with horticultural commodities for the first five years to fill the land until the local fruit produces fruit. Furthermore, local fruit preservation will be determined to realize Kalimantan local fruit agro-tourism. The existence of local fruit agro-tourism in Kalimantan will become a new icon for national agro-tourism, education, and environmental preservation for the archipelago. Government and community support regarding the development of local Kalimantan fruit agro-tourism is urgently needed.

Abstract

Peanut (Arachis hypogaea L.) in Indonesia is an important agricultural commodity after soybean, which has a strategic role in the national food system as a source of protein and vegetable oil. Chili (Capsicum annum L.) is a horticultural commodity with good prospects. The community widely uses it as a cooking spice, an ingredient in traditional medicine, and a mixture in the food industry. The insertion of chili plants into peanut plantations will increase the effectiveness and efficiency of nutrient utilization from the given manure and have a positive economic impact. This study aimed to determine the effect of doses of goat manure and the insertion of chilies on the growth and yield of peanut plants in the intercropping system of intercropping plants. The study used a randomized block design (RBD) with two factors. The dosage of manure with three levels D1 = 2.5 kg goat manure, D2 = 5.0 kg goat manure, and D3 = 7.5 kg goat manure as the first factor, and the insertion of chili plants at the following levels: S0 = monoculture and  S1 = relay cropping with chili as the second factor. The results showed an interaction between the treatments of various doses of goat manure (D) and the addition of plant inserts (S) on plant height aged 56 days after planting, fresh weight, dry weight, and peanut weight. The treatment of various doses of goat manure was not significantly different in all parameters except plant height 42 days after planting. Treatments of chili as relay cropping were not significantly different on all parameters except the weight of 100 peanut seeds. The higher dose of manure causes a decrease in the production of peanuts, which are inserted into the chili plants, but the amount of goat manure can increase the leaf area of the staple peanut plant but has no impact on the total growth/plant dry weight.
