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.

Abstract

The research aims to determine the effect of a combination of inorganic fertilizer (KNO3) and organic fertilizer (goat manure) on the yield of the Betavila variety when apical shoots are pruned. The research took place from March to October 2019 in Kupang Regency, NTT. The research used RAK with 4 repetitions. The treatments are as follows: M1 = inorganic fertilizer 5 g/l KNO3; M2 = organic fertilizer 20 tons/ha goat manure; M3 = inorganic fertilizer 5 g/l KNO3 + organic fertilizer 30 tons/ha goat manure; M4 = inorganic fertilizer 5 g/l KNO3 + organic fertilizer 15 tons/ha goat manure; M5 = Inorganic fertilizer 3.75 g/l KNO3 + organic fertilizer 15 tons/ha goat manure; M6 = Inorganic fertilizer 3.75 g/l KNO3 + organic fertilizer 30 tons/ha goat manure; M7 = inorganic fertilizer 2.5 g/l KNO3 + organic fertilizer 15 tons/ha goat manure; M8 = inorganic fertilizer 2.5 g/l KNO3 + organic fertilizer 30 tons/ha goat manure. The results of the research showed that the combination of applying inorganic fertilizer and organic fertilizer simultaneously influenced the yield of Betavila variety tomato plants whose apical shoots had been pruned, namely on the number of fruits, fruit weight, and fruit production. Fertilization dose of inorganic fertilizer 3.75 g/l KN03 + organic fertilizer 30 tons/ha goat manure gave the number of fruits per plant (59.63 fruit), fruit production per plant (2.63 kg), and fruit production per experimental plot (50.33 kg) highest.

Abstract

Supporting factors for the success of rice planting include seed availability in sufficient quantities, high quality, and availability when needed. Conventional rice seed viability testing generally takes quite a long time, around 14 days. Therefore, it is necessary to develop several methods for quickly testing seed viability. This research aims to determine the coloring pattern of rice seeds, differences in viability tested with 0.25% tetrazolium concentration, and the relationship between the viability values of seeds tested for sprouting and those tested with 0.25% tetrazolium. This research was carried out from March to May 2023 at the Laboratory of the Central Java Seed Supervision and Certification Center. The treatments used were tests using the direct sprout test (rolled paper in plastic test) and the 0.25% concentration tetrazolium test method. The seeds used were seeds with different storage times (0, 1, 2, and 3 months) to obtain variations in seed vigor. The data obtained were analyzed using visual and descriptive analysis, t-test, and correlation analysis. The results showed that the tetrazolium test with a concentration of 0.25% on Inpari 42 rice seeds produced seven coloring patterns grouped into four viable seed and three non-viable seed coloring patterns. The 0.25% concentration tetrazolium test showed that the results had no significant effect and were closely related the results of the direct germination test so the rapid test could be used as a substitute for the (conventional) germination test on a wide scale.

Abstract

The invasion of the ladybug (Vatiga illudens) has started a new chapter in Indonesia, with the first report of this pest in East Java Province in 2021. As a pest that attacks cassava plants, this pest is a threat to cassava plantations, one of which is in Banyumas District, Central Java Province. It is necessary to identify potential natural enemies that can become biological agents that suppress pest populations in the field and insects associated with cassava cultivations to control the pest and anticipate losses due to decreased production of cassava plants in the Banyumas District. This study aimed to explore and describe the natural enemies of ladybug pests and insects associated with cassava cultivations in the Banyumas District. The research was conducted in September 2022-January 2023 in seven cassava cultivation locations in Banyumas District. Samples of pests and or natural enemies were collected using a purposive random sampling method. The results showed a community of potential natural enemies of V. illudens and insects associated with cassava cultivations from the Orders Hemiptera, Diptera, Orthoptera, Coleoptera, and Araneae. The Results showed that 15 species act as potential natural enemies, eight species as pests, and two species as none of them (neutral).

Abstract

Upland rice has the potential to be cultivated on land that has limited water. Plant spacing needs to be done as a strategy so that upland rice can absorb light and water optimally. Apart from that, biochar can be used to improve soil properties so that it is suitable for supporting the growth of upland rice plants on dry land. The study aims to examine the response of biochar application and plant spacing on the growth and yield of upland rice. The study was conducted in the experimental garden of the Faculty of Agriculture, Universitas Perjuangan Tasikmalaya at an altitude of 359 meters above sea level. This study used a factorial Randomized Completely Block Design (RCBD). The first factor is a type of biochar consisting of coconut shells and rice husks charcoal. The second factor is the plant spacing consisting of 20 x 20 cm and 30  x 30 cm. The results showed that there was no interaction between the two treatments on the growth and yield of upland rice. The application of biochar had a significant effect on the number of panicles per hill, while plant spacing had a significant effect on the root length, root wet weight, 1.000 seed weight, and yield. The coconut shell was able to increase the number of panicles per hill, while the wider plant spacing caused an increase in root length, root wet weight, 1.000 seed weight, and yield. In general, the application of biochar can improve crop yields, while regulating the plant spacing has the potential to increase the growth and yield of upland rice.
