Abstract

Chaya (Cnidoscolus aconitifolius (Mill.) I.M. Johnst.) is a perennial leafy vegetable. Since the leaf blade is the most crucial component of the Chaya, it should be advantageous to estimate the leaf area non-destructively.  This research aimed to (a) develop a beneficial non-destructive model for leaf area estimation, and (b) ascertain the impact of stem cutting diameter when used as planting material on chaya growth rate. The results demonstrated that utilizing the length x width (LW) of the middle lobe as the predictor and the zero intercepts linear regression LA = 1.679 LW with R2=0.947 determination coefficient was the most dependable model for Chaya plant leaf area estimation. The stem diameter, which ranged from 9.9 to 17.3 mm, had affected the shoot length, number of leaves, and canopy area between 5 and 7 weeks after planting (WAP). The variations in growth metrics diminished along with the age of plants. The diameter of the stem cutting used as planting material had no effect on the fresh weight of young edible shoot tip at 11 WAP. On Chaya plants that were cultivated with larger stem cutting diameters, the fresh leaf weight at the branch tips was heavier.

Abstract

One of the rice policies was the government purchase price policy which was the price in grain or rice purchases by the Government at producer level to be stable become government rice reserves. The point of this research was to define the impact of the government purchase price policy of rice for producers and consumers. This research was conducted using qualitative analysis with descriptives based on tabulations of secondary data. Results of the research showed that government purchase price was part of the government's efforts to protect the basic price of grain and rice at the farm level thus creating affordable input prices and providing economic added value to farmers. The study found that an improvement in government purchase price  by 18-20% could increase the price of grain and rice from March to August 2023. The total percentage change in prices from March to August 2023 for dry harvested grain was 10.3%, dry milled grain was 10.8%, premium rice was 0.6%, medium rice was 3.2% respectively. Meanwhile, the impact on consumers of this policy was the occurrence of inflation of 0.41% which caused rice prices to increase. The government should evaluate the Government Purchasing Price (GPP) gradually every year.

Abstract

Prayoga, A., Gustiar, F.,  Marlina, M., Budianta, D., Ammar, M., Susilawati, S. (2023). Growth and yield of mustard (Brassica juncea L.) intercropping chaya plants (Cnidocolus aconitifolius) with different canopy sizes. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 306-317).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Intercropping is planting pattern that cultivates more than one type of plant in a certain unit of time aimed at increasing productivity. This study was conducted to examine the size of the chaya plant crown and the density of mustard plants using an intercropping system in the area of chaya plants (Cnidoscolus aconitifolius) in order to obtain optimal production and growth results. This study was conducted using a split plot design with two factors. The first factor as the main plot of the cultivation system is 3 treatments, namely conventional / monoculture (K0), intercropping on chaya plants with a header diameter of 80 cm (K1), and intercropping on chaya plants with a crown diameter of 120 cm (K2). The second factor is the density or planting distance as a child plot with a planting distance of 15 x 15 cm (P1), and a planting distance of 15 x 20 cm (P2). The data that has been obtained is then analyzed by the Analysis of Variance (ANOVA) method using the R-Studio application. The results showed that the cultivation of mustard greens (B. juncea L.) tosakan variety with intercropping patterns on conventional obtained the best results. But the 80 cm chaya plant canopy is not significantly different from conventional planting patterns so it can be said that the 80 cm chaya canopy is better than the 120 cm chaya plant canopy. The optimal planting distance is a planting distance of 15 x 15 cm because it is not significantly different from a planting distance of 15 x 20 cm in terms of the quality of the results obtained. In terms of quantity, a planting distance of 15 x 15 cm will produce more production results than a planting distance of 15 x 20 cm. So it can be concluded that the cultivation of mustard greens (B. juncea L.) varieties of intercropping chaya plants (Cnidoscolus aconitifolius) can be done on the chaya crown 80 cm and with a planting distance of 15x15 cm.

Abstract

Rice fields that were intensively cultivated by the application of chemical fertilizers for a long time may experience declining rice production, as the soil ages. Therefore, it is necessary to assess the fertility of the paddy soil for rice cultivation. Site-specific balanced fertilization is determined based on soil test results that represent the in situ soil chemical properties. This study aims to analyze the fertility level of paddy fields and determine the optimal amounts of nitrogen (N), phosphorus (P), and potassium (K) fertilizers for rice growth, considering the soil fertility status in Marga Cinta, Belitang Madang Raya District, Ogan Komering Ulu Timur of South Sumatra, Indonesia. The study employed a random sampling method, with a total of 6 samples collected by drilling at a depth of 0 - 30 cm, and then composited. The results revealed that the fertility of the paddy soil at the study site was relatively low, with an average pH of 5.32, organic carbon content (C-Organic) of 0.67%, cation exchange capacity (CEC) of 9.85 cmol/kg, base saturation of 21.05%, total nitrogen (N-total) of 0.10%, available phosphorus (P-available) of 1.87 mg/kg, and exchangeable potassium (K-exchangeability) of 0.10 cmol/kg. Based on these findings, the recommended fertilization amounts are 199.89 kg/ha of urea, 147.91 kg/ha of SP-36, and 28.45 kg/ha of KCl.

Abstract

Mixing urea with natural materials that can reduce the rate of urea dissolution is known to increase the N availability replenished by inorganic fertilizers which absorbed by plants for growth and production.This study aimed to examine the effective of application of pellet N fertilizer prepared by coal fly ash- azolla and urea on the response of corn planted in acidic Ultisol. This pot experiment was performed in the greenhouse and soil analysis was conducted in the Laboratory of Chemistry, Biology and Soil Fertility, Soil Science Department, Faculty of Agriculture, Sriwijaya University. The research was arranged using a completely randomized design with nine treatments and three replications. The treatments applied were a mixed composition materials (w/w) of 50% coal fly ash + 50% azolla, and 40% coal fly ash + 60% azolla respectively. Each composition (w/w) of 70% coal fly ash- Azolla mixture was then incorporated by 30% urea and compacted as pellets using a manual screw extruder. In addition, to compare the effect of pellet, it was done the other treatment by granular urea fertilizer only applied by immersing and sowing on the soil surface. The results showed that the application of N slow release using the pellet forms significantly increased N availability, plant N uptake, plant height and dry weight of corn. The N slow release as a pellet can reduce the dose of N inorganic fertilizer as urea by 25%. The response of corn at a dose of 0.75 times is not significantly different from the dose of 1 times the recommended dose of N.

Abstract

Agriculture serves as a critical sector underpinning the livelihood of the Indonesian population.. Thus the implementation of this sector involves the use of fertilizers as inputs. However, A prevalent misconception among farmers is that increased fertilization invariably leads to enhanced yield. Excessive fertilization using inorganic compounds, such as phosphorous (P) can elevate levels of Cadmium (Cd), which is a potentially toxic metal for the environment and humans. Therefore, this study aimed to investigate the concentration of the heavy metal cadmium (Cd) in both soil and rice plants in Marga Cinta, Belitang Madang Raya District, East Ogan Komering Ulu Regency, South Sumatra, Indonesia. The method involved a comprehensive survey approach and spanned across 96-hectares of paddy fields, which were divided into six distinct locations. Each location comprised 16 hectares of rice fields, with five sample points drilled to a depth of 0-30 cm. The results showed that the content of Cd in paddy soil and rice plants had exceeded national food safety standards. Hence, farmers were advised to balance their use of phosphorus-rich fertilizers with organic ones, mitigating the rise in soil Cd content. This balance necessitates a reduction in the usage of other chemical fertilizers, favoring organic fertilization methods to promote phytoremediation

Abstract

Sweet corn is a food crop that has a sweeter taste than ordinary corn. It has high economic value and has a shorter harvest time. The demand for corn is increasing in Indonesia but corn production is not sufficient to meet it. For this reason, efforts to increase sweet corn production are needed to consume the people. The purpose of this study was to determine the effect of oil palm bunch ash and cow manure ameliorants on the growth and production of sweet corn (Zea mays saccharata Sturt) on peat soil. The pot experiment was conducted in Bandar Agung Village, Lalan District, Musi Banyuasin, South Sumatra of Indonesia dated from December 2022 to March 2023. This study used a Randomized Factorial Block Design which consisted of 2 factors which were the first factor was dose of oil palm bunch ash consisting of control, oil palm bunch ash at 20 tons ha-1 and 60 tons ha-1. The second factor was dose of cow manure at control, 42 tons ha-1 and 84 tons ha-1. Total treatment was 9 combinations and it were repeated 3 times. For each treatment was left 2 plant samples. The results showed that no significant effect for plant height, number of leaves, plant fresh weight and plant dry weight. Application of 60 tons ha-1 of oil palm bunch ash + 42 tons ha-1 of cow manure showed the best combination results on sweet corn growth because it has the highest found on each variable observed.

Abstract

Mustard greens are one of the vegetable commodities plants. The part used is the young leaves, which can be processed into traditional medicinal and vegetable ingredients that benefit human health. This research aims to determine the level of shade tolerance on the growth and yield of mustard plants and determine mustard varieties that are tolerant of minimum sunlight conditions. This research was carried out in experimental fields using artificial fields in June – July 2023. This research used a split-plot design with 2 factors. Tafif shade as the main plot consists of no shade 0%, 55%, 70%, and 95%. The sub-plot varieties consist of the Tosakan variety and the Kumala variety. The results of the research indicate that sunlight intensity reduction negatively impacted the growth and yield of mustard plants. However, under 55% shade conditions, there was no significant difference observed in the growth and yield of mustard plants compared to those grown without shade. The Tosakan and Kumala varieties did not show any differences in the growth or yield of mustard plants.

Abstract

Tidal lowland is a marginal land characterized by low pH, deficient  nutrients, and salinity. Despite these challenges, El Niño phenomenon often occurs during the second planting season, resulting in long droughts. However, tidal lowland must be used for cultivation due to the need for rice and the land should be treated accurately. Therefore, this research aimed to address the issues by improving the efficiency of rice cultivation on tidal lowland through precision farming practices. A survey and land analysis were conducted in tidal lowland of B typology in Delta Saleh, Indonesia, from March 2023 to June 2023. In this precision farming practice, water management was highly prioritized, starting from tertiary channels such as optimizing sluice gate operations and monitoring water levels in channels and groundwater. Additionally, pH, CEC, and C-Organic analysis were also carried out in rice cultivation, as showed by the  equation Y = 0.15 - 0.001 pH + 0.000 CEC + 0.000 C-Organic. The highest production yield was 2.05 tons/ha in P5, with the SEW-10 value during cultivation activities being 778 cm and the number of days above -10 reaching 84. Moreover, the efficiency of rice cultivation was improved through precision agricultural practices by using valve sluices and levees.
