Abstract

Cercospora personata is a pathogen that causes leaf spot disease, as one of the important diseases of peanut plants, known to reduce the rate of photosynthesis to reduce plant production by up to 50%. The handling of Cercospora attacks so far is still focused on the method of spraying fungicides. Potassium fertilization is known to increase plant resistance from one of the Cercospora attacks. The right dosage to overcome Cercospora attacks needs to be studied so that the method of fertilizing potassium in peanut plants can be implemented effectively. This study was conducted in an experimental garden using 5 dosages of potassium and repeated 3 times. The composition of the treatment used is: D0 (control), D1 (2 gr of potash fertilizer per plant), D2 (4 gr of potash fertilizer per plant), D3 (6 gr of potash fertilizer per plant) and D4 (8 gr of potash fertilizer per plant). Weekly observations were made on the variables of plant height, number of leaves, number of saplings, as well as the intensity of disease attacks. The results showed that the dose of potassium had a significant effect on several components of plant growth and the intensity of disease attacks. The application of potassium as a fertilizer has a significant influence on the observation components of the number of leaves (plant age 8, 10, and 12 MST), the number of saplings at plant age 10 MST, and the intensity of leaf spot disease attacks (plant age 8, 10, and 12 MST). Plants that were not given potassium showed leaf spot disease attacks with the highest intensity compared to the other four treatments. This pattern was seen at observation ages of 8, 10, and 12 MST.

Abstract

This study aims to determine the response of peanut gowth and production of local variety Kebar to goat manure treatment and peanut seed size. The method used was an experiment with a factorial randomized block design with two treatments. The first treatment was fertilizer dosage with 3 levels and the second treatment was seed size with 2 levels. Three levels for fertilizer doses, namely P0: 0 g/polybag; P1: 150 g/polybag, P2: 300 g/polybag. Two levels for seed size, namely, B1: small seed size (0.5 g) and B2: large seed size (0.8 g). The data was then analyzed using analysis of variation (Anova). If the treatment shows results that have a real effect, then continue with the DMRT further test. The results showed that the P2B2 treatment showed a higher leaf number and plant weight than the other treatments. However, the application of goat manure and seed size had no effect on number of pods, pod weight per plant, number of filled pods and 50 seed weight.

Abstract

The agricultural sector is a strategic sector in national development. The increase in production has been given by agricultural extension activities. The agricultural instructor must be someone who is competent in the field of agriculture and can communicate effectively and be responsive in dealing with every problem and question quetioned by farmers. The centers for shallot production in Papua Province are Kerom, Merauke, Tolikara and Jayawijaya Regencies. Shallot farming is always faced with risks. in the form of a decrease in production due to unpredictable weather factors and attacks by pests and diseases (such as wilt disease). To overcome the problems above, an agricultural instructor is needed who can help farmers in diagnosing pests and diseases of shallot plants. The research aims to determine the role of agricultural instructors for shallot farmers in controlling plant pests. This research was carried out in Arsopura village, Skanto District, Keerom Regency for 6 months from August 2022 to February 2023. This research used the Arithmetic Mean analysis method with average assessment criteria of 1.00-1.66 with categories of No Role, 1.67- 2.33. There were 60 questions asked by the resource person for each indicator, with 17 facilitator indicator questions, 15 motivator questions, 14 educator questions and 15 communicator questions. The results of the research show that agricultural extension workers play a role in controlling pests and diseases in shallot plants. The scores obtained for the facilitator indicator were 2.69, motivator 2.69, educator 2.34, and communicator 2.44, each in the Role category. Agricultural instructors play a very important role and always provide new technologies to increase shallot production, in Arsopura Village, Skanto District, Keerom Regency.

Abstract

This research aimed to determine how sweet potato growth responds to a monoculture cropping system and intercropping with corn. This research was carried out for 4 months December 2021 to April 2022 on the land of PT. Eiber Shuth Coklat Ransiki (Cokran) Cooperative in South Manokwari Regency. This research conducted in Randomized Group Design consisting of two treatments of cropping patterns, namely monoculture and intercropping patterns. The variables observed were length of tendrils, number of leaves, number of branches, fresh weight and dry weight of sweet potato grown in two different cropping patterns. The results of the tabulated analysis showed that the number of leaves, number of branches, length of tendrils and dry weight of sweet potato plants cultivated in monoculture was better than in an intercropping pattern with corn. However, the fresh weight of sweet potato in the intercropping pattern with corn is higher compared to those from the monoculture.

Abstract

Agricultural activities on tidal marshland are strongly influenced by the tide (rise) and ebb (fall) of sea or river water. This study aims to (1) Determine soil physical and chemical property criteria; (2) Evaluate soil fertility; and (3) Evaluate tidal paddy suitability. The research site is in the tidal lands of Kamundan District of Teluk Bintuni Regency. The method used is a descriptive method with a survey technique. The results of the study were obtained (1) Criteria of physical and chemical properties of the soil has the physical properties of dusty clay. Soil chemical properties are average slightly acidic pH, low C-organic, medium, high, low to moderate N-total, very low to low P-available, very low to low Potassium, very low KTK, and high KB. (2) Soil fertility status is classified as low which is influenced by low values of P-available and Potassium soil. Low p-available soils are present on (river embankments, switchbacks and back bogs) and Low classified soil Potassium is present on river embankments, and (3) The results of land suitability analysis obtained on river embankments have an actual land suitability class of S3Na with limiting factor P-available, Very low Potassium can be upgraded into potential land suitability by performing Phosphate and Potassium fertilization with proper dosages and schedules, addition of organic matter through the use of manure. In the Intermediate and Back Swamp areas obtained the actual land suitability of S3na with a very low Potassium limiting factor can be increased to potential land suitability by performing Potassium fertilization with proper dosage and schedule, addition of organic matter through the use of manure.

Abstract

This research aims to determine the effect of stem cutting size on the growth of Gembili. The design used in this research was a Randomized Group Design (RAK) with 4 treatments repeated 3 times. The research treatments were M1 = cutting length 20 cm, M2 = cutting length 30 cm, M3 = cutting length 40 cm, and M4 = cutting length 50 cm. Data analysis uses variance, if the treatment has a significant effect, then the analysis continues using the Least Significant Difference test (LSD) with a confidence level of 95%. The results showed that the size of the cuttings had no significant effect on the growth of Gembili in all growth variables. The length of cuttings of 50 cm tended to show the highest increase in average values for all observed growth variables.
