Abstract

The study aimed to compare several production parameters of Panicum sarmentosum at different defoliation intervals whose its benefit can add knowledge about the favorable defoliation interval of grasses as a feed forage source. The agronomic study was done in plot experiments comparing parameters such as number of tillers, percentage of flowering clumps, forage dry-matter (DM) content, forage DM production, and leaf:stem ratio as an effect of 3 defoliation interval treatments, namely; 4, 5, and 6 weeks with 3 repetitions. The effect of treatment on parameters was determined by the analysis of variance. Significant parameters affected by treatment were then further tested to determine the best defoliation interval between treatments by using the least significancy difference test. The results showed that the number of tillers, the percentage of forage DM content, the production of stem DM (kg/ha) and the leaves stems ratio were not affected by the defoliation interval. Defoliation interval significantly (P<0.05) affected the number (%) of flowering clumps, the production of forage biomass (kgDM/ha), and the production of leaf DM (kgDM/ha) of Panicum sarmentosum Roxb. grass. The one-year observation obtained on the productivity of Panicum sarmentosum Roxb. has not reflected the survivability and productivity of this type of superior local forage yet.

Abstract

The most essentials factor underlying water management are the characteristics of plants to water requirements, the amount of water given, the irrigation methods, and the characteristics of the soil in storing water. The research purpose is to identify and determine the best irrigation method, which can increase the growth and production of soybean plants. Knowing the best method of giving water/irrigation that is able to maintain soil moisture for soybean plants. The experiment used a randomized block design consisting of four treatments, namely: A0 = Control, A1 = Sprinkle Method, A2 = furrow method, and A3 = Flood method. Each treatment was repeated three times. The data were analyzed statistically and if there was a significant effect, it would be continued with an test of honestly significant difference. The results showed that the Flood method gave the best effect on almost all parameters of growth and production observations and the highest yield for production per hectare was 4.32 tons.

Abstract

Indonesia's mangosteen exports to several Asian countries, Europe, and the Middle East have increased yearly, especially during the Covid19 pandemic. However, efforts to improve domestic mangosteen cultivation technology are inadequate. The research materials used include 45 mangosteen trees accessed by Donggala and Sigi already producing (age + 20 years) and Urea, TSP, and KCL fertilizer. The tools used are meters, plastic labels, calipers, digital scales, Smartphones, and GPS Garmin 64 Sc. Using a RandomIzed Group Design (RAK), one factor, namely fertilization, consists of three levels of treatment in each District. The observation results were analyzed using ANOVA, and if there was a significant influence, it was continued with the BNJ analysis. The results showed that fertilization treatment using BALITBU TROPIKA Solok and analysis results from the Soil Science Laboratory Unit of the Agriculture Faculty University of Tadulako increased plant height and triangular area stamina by 100 to 300 percent compared to without fertilization. There was an increase in plant height and triangular stamina area by 100 to 300 percent compared to without fertilization. There was an increase in plant height and triangular area stamina by 100 to 300 percent compared to without fertilization. There was an increase in production of fruit height from 155 to 394 percent, fruit/seed locul number from 101 to 106 percent, fruit production per tree from 175 to 178 percent, and fruit diameter from 119 to 137 percent.

Abstract

South Banawa District is one of the areas in Donggala Regency which has the best prospects in the pond aquaculture sector because this area has the potential to produce milkfish and shrimp. The earthquake and tsunami of 28 September 2018 damaged most of the ponds in South Banawa District. This study aimed to analyze the composition, diversity, and dominance of plankton in fish and shrimp farming ponds in Lalombi and Tolongano Village. The diversity index (H ́) of plankton in the two villages, namely Lalombi, ranges from 0.3040-1.0769 (phytoplankton), 0.4385-0.4610 (zooplankton) and Tolongano, it ranges from 0.2219-1.2318 (phytoplankton), 0-1.3297 (zooplankton). The results of this diversity are included in the low community category, which means that the condition of the plankton community is unstable, so the condition of the community is experiencing environmental disturbances, caused by changes in the structure of the soil texture due to the earthquake and tsunami. The dominance index values ranged from 0.4227-0.9033 for and from 0-0.2778 for Dominance index values close to one mean that under current conditions there is a dominant type of but for the value was close to zero, which means that there was no species dominating the structure of the community. uniformity index values ranged from 0.1562-0.4957 and those for ranged from 0-0.9592.

Abstract

Local commodity-based farming needs to be developed by improving activities upstream to downstream of agricultural industries. Turmeric is one of the local commodities in Ngepung Village, Kedamean District, Gresik Regency. This commodity, which is widely used in food and beverage, and has health benefits, has not been cultivated intensively by some farmers in the area, mainly as a secondary commodity. The lack of access to information received caused the low willingness of the farmers to develop a turmeric business. However, some farmers have worked in small to medium-scale businesses because they can produce high production. This study analyzes the factors influencing farmers' decisions to sell turmeric. The analytical method used is binary logistic regression analysis. The results indicate that the price and production have a significant effect on farmers' decisions in selling turmeric. In contrast, the variables of distance to the market, age, education, and experience in turmeric farming have no significant effect.

Abstract

The relationship between several characters of yields is very important for developing effective selection criteria. The total correlation between the result character and the result component may be misleading as a result of its relationship with other characters. Separating the total correlation into direct and indirect effects provides a more significant explanation of the cause of the relationship between dependent variables such as yield and independent variables such as yield components. This study aims to determine several traits that can be used to make selections indirectly and directly to increase the yield of upland rice. This research has been carried out on agricultural land in the village of Tamarenja (Kalama), Sindue District, Donggala Regency. Starting from August to December 2019, using a Randomized Block Design (RBD) with seven genotypic cultivars and three groups of cultivars so that there were twenty one experimental plots. The results showed that the number of leaves, leaf length, number of tillers, number of productive tillers, flowering age, thickness of seeds and weight of 1000 grains had a positive and significant correlation to yield. Flowering age, 1000 grain weight, and number of tillers are some of the characteristics that have a high direct effect and significant correlation to upland rice yield.
