Abstract

Evaluation of Rice Field Fertility Status Based on Geographical Information System in Negara District, Jembrana Regency Lowland rice production at Negara District in 2014 was 6.89 tons/ha and in 2015 decreased to 6.67 tons/ha. This is thought to be due to the reduced ability of the land to support the agricultural production process. The purpose of this study was to determine the status of soil fertility and the parameters of the limiting factors of soil fertility, to make a map of the status of soil fertility, and to provide direction for the management of soil fertility. This research was conducted from December 2021 – March 2022. The methods used in this study included survey and soil test methods with parameters of fertility status including: CEC; BS; organic C; total P and total K. The results showed two soil fertility statuses in the study area, namely low in HLU I (Pengembengan Village, West Tegal Badeng, East Badeng Tegal, Baluk, Banyubiru, Kaliakah, Lelateng, Bale Agung Baler) and HLU II (Pengambengan Village, East Tegal Badeng, Banyubiru, Lelateng) and moderate soil fertility in HLU III (Kaliakah Village, Berangbang, Bale Agung Baler) and HLU IV (Kaliakah Village, Berangbang, Bale Agung Village). The limiting factors for soil fertility status were CEC and moderate K2O content and low organic C content. The direction of soil fertility management is the addition of organic matter and K fertilizer to improve soil fertility status.

Abstract

Effectiveness of Some Synthetic Fungicides to Scabies Disease Pathogen (Diaporthe phaseolorum C.&E.) Growth on Siam Orange Fruit (Citrus nobilis L.) Siam orange is one of the main commodities produced in Payangan District, Gianyar, Bali. Unfortunately, the Siam orange is often attacked by scabies. This disease is named scabies because it produces scab-like lesions that develop mainly on the skin of the fruit. Scabies is caused by the fungus Diaporthe phaseolorum. In order to increase the production of Siam oranges in Payangan, it is necessary to control this pathogen. The purpose of this study was to determine the effectiveness of synthetic fungicides in controlling scabies in Siam orange fruit and to determine the most effective synthetic fungicides to use. This research was conducted in a citrus orchard in Kerta Village, Payangan District, Gianyar, Bali. PS3 treatment Mankozeb + Mefenoxam, was the most effective in suppressing the growth of scabies in Siam oranges. The average PS3 is the smallest in the percentage of disease per tree, which is 70%, followed by the average fruit diameter of PS3 which produces the largest fruit, which is 19.25 cm, as well as the average intensity of PS3 disease is the smallest, which is 24.63%. The results of observations carried out showed that the administration of synthetic fungicides was effective in suppressing the growth of pathogens that cause scabies in Siam oranges in Payangan, especially the synthetic fungicide Mankozeb + Mefenoxam.

Abstract

Effect of Dolomite Application on the Quality of Corn Seeds (Zea mays L.) on Acid Soil in Experimental Gardens, Faculty of Agriculture, Udayana University The decline in maize production in Bali is caused by various factors such as poor cultivation techniques, lack of agricultural land due to land conversion, limited fertile land due to acidic soil conditions and the availability of quality seeds that are still lacking. The application of dolomite on acid soil is expected to improve the quality of corn seeds. This study aims to determine the difference in the effect of dolomite application and without dolomite application on acid soil on corn seed quality (physical and physiological quality). This study used a paired experiment to compare the quality of corn seeds produced with dolomite application and without dolomite application. The results showed that the application of dolomite was able to significantly increase the average weight of 1000 seeds, germination, shelf life vigor, growth speed vigor of 2.55%, 1.23%, 6.27%, 3.43 % when compared with no dolomite application, while the simultaneous growth of vigor showed no significant difference between dolomite application and without dolomite application.

Abstract

The Relationship between Soil Organic Matter Levels with Diversity of Soil Macrofauna on Agricultural Land in Baturiti District This study aims to determine the level of soil macrofauna diversity on agricultural land in Baturiti District and to determine the relationship between soil organic matter levels and soil macrofauna diversity on agricultural land in Baturiti District. Sampling locations were taken on two types of land use, two organic land cultivation systems at an altitude of 903-1259 meters above sea level and conventional land at an altitude of 925-1173 meters above sea level. The method in this study is the sampling method, taking soil macrofauna and soil organic matter by direct observation to the research location at the sampling point, namely 5 types of organic agricultural plants and 5 types of conventional agricultural plants which are considered representative of the presence of soil macrofauna and represent each type of plant in the study area. Soil macrofauna sampling was carried out using 2 methods, namely pit fall trap, quadratic method and hand sorting. Sampling of organic matter was carried out by hand sorting method, on organic and conventional land in Baturiti District. Soil macrofauna found in organic and conventional land were identified and calculated values: Diversity index (H'), Abundance index (R1), Dominance (C). Soil from organic and conventional land was analyzed for organic matter content (C). The data obtained were analyzed by hypothesis testing (t) using the SPSS application to determine the relationship between soil organic matter content and soil macrofauna. The results of this study indicate that the level of soil macrofauna diversity on organic land with an altitude of 903-1259 mdpl is in the medium category (1.493- 2.421) and the level of soil macrofauna diversity on conventional land with an altitude of 962- 1318 mdpl is in the medium category (1.011- 1,961). On organic land with an altitude of 903- 1259 mdpl and conventional land with an altitude of 962 mdpl and 1173 mdpl, there is no relationship between soil organic matter content and macrofauna diversity. Based on the results of the hypothesis test, it was shown that it was rejected. On conventional land with an altitude of 1318 meters above sea level, there is a relationship between soil organic matter content and macrofauna diversity. Based on the results of the hypothesis test, it shows that it is accepted.

Abstract

Effect of Manure Type and Dosage of Liquid Organic Fertilizer from Banana Stem Waste on Soil Chemical Properties and Yield of Green Spinach (Amaranthus hybridus L.) Organic fertilizers can improve the physical, chemical and biological properties of soil because they contain macro and micro nutrients that are useful for plants. This aims of the study to determine the interaction and effect of type of manure and dosage of Liquid Organic Fertilizer (POC) on soil chemical properties and yield of green spinach which was carried out from July 2021 to November 2021 in Sukadame Village, Tigapanah District, Karo Regency, North Sumatra Province. Banana tree trunks are useful for fertilizing plants, and contain very high phosphorus nutrients. The experimental design used in this study was a completely randomized design (CRD) with a factorial pattern consisting of 2 factors, namely the type of manure and the dose of liquid organic fertilizer with, A0: no manure, A1: goat manure, A2: chicken manure, A3 : cow manure, while the doses of liquid organic fertilizer are B0 : without liquid organic fertilizer, B1 : 0.75 liters of liquid organic fertilizer, B2 : 1.50 liters of liquid organic fertilizer and B3 : 2.25 liters of liquid organic fertilizer and repeated 3 times so that it becomes 48 units of experimental pot. The interaction between the type of manure and the dose of liquid organic fertilizer had a very significant effect on organic C, available K and available P content. The best manure is chicken manure with soil pH (6.40), soil moisture content (16.45%) and total N content (0.66%). The best change in soil chemical properties was treatment with a dose of liquid organic fertilizer at a dose of 0.75 liters, with soil pH (6.40), soil moisture content (17.29%) and total N content (0.67%), and for influence. the yield is at a dose of 0.75 liters of liquid organic fertilizer with a fresh plant weight of 10.83g.
