Abstract

This study aims to determine the effect of liquid organic fertilizer (LOF) made from rabbit urine on the growth and yield of caisim. This research was conducted using a randomized block design (RAK) consisting of 5 treatments and 6 replications so that 30 experimental units were obtained. The treatments were A0 (control) without LOF, A1 (LOF 30 ml/l water), A2 (LOF 60 ml/l water), A3 (LOF 90 ml/l water), A4 (LOF 120 ml/l water). The results showed that the LOF treatment of rabbit urine at the concentration of 30-120 ml/liter of water gave a significant effect on the components of plant fresh weight and economic fresh weight, while it had no significant effect on the plant growth component. The appliction of LOF rabbit urine with a concentration of 30 ml/liter of water is sufficient enough to get the best fesh weight of caisim.

Abstract

This study aims to determine the appropriate application time interval of rabbit urine POC to support optimal growth and production of mustard greens. This study used an experimental method designed using a completely randomized design (CRD) with 4 treatments, including W0 (control), W1 (treated with 60 ml/L rabbit urine every 1 week), W2 (treated with 60 ml of rabbit urine /L every 2 weeks), and W3 (treated with 60 ml/L rabbit urine fertilizer every 3 weeks). Variables observed in this study included growth variables consisting of plant height, number of leaves, leaf width, and leaf length at 1 – 6 WAP, as well as production variables in the form of wet stover weight per plant (grams) and plant consumption weight (grams) at 6 WAP. The data obtained were analyzed by ANOVA and if it had a significant effect then continued by the Tukey test at the 95% level of confidence. The results of the study showed that the time interval treatment for application of POC rabbit urine only had a significant effect on the variable number of leaves, leaf length, and leaf width at 6 WAP and plant consumption weight. The time interval application of 2 weeks (W2) rabbit urine POC tend to give better results than other time interval treatments in almost all observation variables.

Abstract

This study aimed to determine the effect of applying several organic fertilizers (Papua Nutrient liquid fertilizer, Green Tonik liquid organic fertilizer, Nasa liquid organic fertilizer, Agrica liquid organic fertilizer) and inorganic fertilizers (CPN, NPK 16 : 16 : 16 fertilizer, Solution liquid fertilizer, Urea + KCl + TSP, SP 36) on the growth and production of mustard greens. The design used in this study was a randomized block design (RBD) with 10 treatments which were repeated 3 times. The research treatments were S0: Without Treatment, S1: Papua Nutrient (10 ml/liter of water), S2: POC Green Tonic (3 ml/liter of water), S3: POC Nasa (2 ml/liter of water), S4: POC Agrica ( 5 ml/ liter of water), S5 : CPN fertilizer (5 gram/ plant), S6 : NPK 16 : 16 : 16 (5 gram/ plant), S7 : Liquid chemical fertilizer solution (4 ml/ liter of water), S8 : Urea + KCL + TSP (5 grams/plant) and S9 : SP – 36 (5 grams/plant). Data were analyzed using variance. If the treatment has a significant effect, then the analysis is continued using the Least Significant Difference Test (LSD) with a 95% confidence level. The results showed that the application of several organic fertilizers and inorganic fertilizers showed a significant effect on plant height 3 WAP, number of leaves 3 WAP, number of leaves 4 WAP and plant fresh weight per plot, and had a very significant effect on plant height 4 WAP, leaf width and plant fresh weight per plant. The fertilizer treatment that showed the best results on average was NPK 16: 16: 16 (S) and Urea + KCl + TSP (S8) fertilizers, while the fertilizer treatment that showed the lowest results was Papua Nutrient fertilizer (S1).

Abstract

This study aimed to 1) predict the phenotypic diversity between local Papuan cassava genotypes, 2) determine the characters that make the greatest contribution to diversity and 3) determine the characters that have the same degree of similarity. This research was carried out from April 2020 to March 2021 in the Manggoapi experimental garden, Faculty of Agriculture, University of Papua. This research was an observational study, and used purposive sampling method in the form of qualitative research without spatial planning, as well as descriptive analysis techniques to describe the data obtained. The cassava used in this study totaled ten genotypes without control and replication treatments. The variables observed consisted of morphological characters combined with agronomic characters, which included 46 morpho-agronomic characters. Based on the results of the study it can be concluded that 1) there was broad and narrow phenotypic diversity between 10 local Papuan cassava genotypes from the UNIPA Genetics and Plant Breeding Laboratory collection, broad characters were more dominant than narrow characters, because the cassava observed was more influenced by genetics than environment. (2) The eigenvalues of the morpho-agronomic characters of the 10 local Papuan cassava genotypes ranged from 1.614-10.687 with a character contribution of 98.041% indicating that the morpho-argronomic characters made a large contribution to the 10 observed Papuan local cassava genotypes. (3) 10 local Papuan cassava genotypes collected by the Genetics and Plant Breeding Laboratory of UNIPA which were analyzed using clusters obtained results with a coefficient value of 65%, there was the same similarity between the Amban 3 and Amban 4 genotypes, as well as for the Amban 5 and Amban 8 genotypes.

Abstract

This study used a Factorial Completely Randomized Design (CRD). The first factor was planting media (M) which consisted of three categories, namely: topsoil (M0), mixed soil and goat manure with a ratio of 2:1 (M1), soil and chicken manure with a ratio 2:1 (M2). The second factor was foliar fertilizer (P), which consisted of no foliar fertilizer (P0) and application of gandasil D fertilizer (P1). The results showed that the M0 treatment had a significant effect on the weight of the pods and the fresh weight of the plant, but did not have a significant effect on the plant height, the number of branches and the flowering time. The application of gandasil D has no significant effect on all observed variables. The combination of media type and gandasil D had a significant effect on plant height at 3 WAP in the M2P1 treatment, the number of pods in the M2P1 treatment, the weight of the pods planted in the M0P1, M0P0 treatments, and the fresh pod weight in the M0P0, M2P1, M1P0 treatments, but had no significant effect on plant height, number of branches and flowering time. In the observed variables of pod weight and fresh pod weight, the application of animal manure gave a good response to the availability of nutrients that can be absorbed by plants.

Abstract

Land availability and crop productivity are important in realizing sustainable agriculture in West Papua. This study aims to provide an overview of agricultural development in West Papua in terms of agricultural aspects and changes in land use. This research is descriptive-analytic in nature, using population data for the period 2003-2018, data on paddy rice, cassava, sweet potato, dry-field rice and corn. Land use data for the 1996-2019 period and potential agricultural land cover for 2021. The results obtained are an average population growth rate of 3.4 percent. The conditions of lowland rice, cassava and sweet potato crops for the 2004-2018 period are as follows: The average productivity of lowland rice is 3.72 tonnes/ha or 37.2 quintals/ha. Cassava production was very fluctuating, which was obtained that the average productivity of cassava was 12.03 tons/ha or 120 quintals/ha. Sweet potato crop productivity decreased in 2018 with an average sweet potato productivity of 11.11 tons/ha or 111.1 quintals/ha. The condition of dryland paddy and maize for the 2003-2017 period showed that the production and harvested area of upland paddy tended to decrease every year with an average dryland paddy productivity of 2.86 tons/ha or 28.6 quintals/ha while corn productivity continued to increase until 2017 with the average productivity is 1.78 tonnes/ha or 17.8 quintals/ha. Aspects of changes in land use in the agricultural sector for the period 1996-2019 obtained that dryland agriculture and mixed dryland agriculture tended to decrease.

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.
