Abstract

[COMPARISON OF GROWTH AND YIELD OF SOME  INTRODUCED VARIETIES OF CABBAGE  DURING THE RAINY SEASON IN PURBALINGGA]. Cabbage (Brassica oleracea var capitata L.) is a type of vegetable plant from the Brassicaceae family that has great potential for cultivation because it has an economic value and very high nutritional contents. This research aimed to evaluate the introduced cabbage varieties that have the best growth and yield in the highlands of Purbalingga Regency. The research was carried out in Serang Village, Karangreja District, Purbalingga Regency, in February-June 2023. The site was located at an altitude of 1,250 m above sea level. The experiment was arranged in a completely randomized block design (CRBD) with treatments consisting of six introduced cabbage varieties, namely Omphalos, Oxylus, Tropicana, Kaelo, Saint, and Dolares, as well as two comparison varieties, namely Grand 11 and Green Nova. Introduced cabbage varieties have varied growth, which was observed in the variables of plant height, number of leaves, age of crop formation, root length, fresh weight of roots, and age of harvest. The crop fresh weight yields for the introduced varieties Kaelo, Tropicana, and Oxylus were respectively 721.1, 683.3, and 650.8 g/plant, which was relatively uniform with the comparison variety Grand 11, namely 637.5 g/plant.

Abstract

[ANALYSIS OF MANGROVE  LAND CAPABILITIES IN SURABAYA CITY  UTILIZING GEOGRAPHIC  INFORMATION SYSTEM]. Mangroves are experiencing rapid growth and require optimal management. Assessing the land potential is crucial for developing necessary policies to evaluate mangrove areas and determine their suitability for mangrove plantations. Findings from land evaluation offer valuable guidance for land use according to specific requirements. Assessing land capacity serves as a reference to determine suitability, with mapping based on mangrove vegetation in the Surabaya region. This research aims to identify and assess the suitability of land along the Surabaya coast for mangrove cultivation. Results indicate that mangroves in Surabaya City fall into ability classes V and VII. Limiting factors include drainage conditions and physical properties such as soil texture, permeability, and salinity. Proper land use is determined based on land capability classes, designating areas as nature reserves and protected forests.

Abstract

[EFFECT OF BENZYL AMINO PURIN ON SHOOT INDUCTION OF AGLONEMA (Aglonema commutatum Schott.)]. The Aglonema is a well-known ornamental plant and has a high selling value in Indonesia. It is characterized by attractive and beautiful leaves because of its diversity of colors and motifs. The Aglonema commutatum Schott plant is a type of Aglonema which is characterized by green leaves with white markings. The increasing demand for Aglaonema, both imports and exports, makes it impossible to propagate through seeds and cuttings, so it is important to optimize propagation through effective tissue culture. The aim of research was to determine effect of various concentrations of the BAP Benzyl Amino Purin on the shoot induction of A. commutatum plants. The explants used were the stem nodal parts which were planted in Murashige and Skoog media. The research design used CRD with a BAP concentration factor consisting of 6 levels, namely 0 mg/L, 4 mg/L, 8 mg/L, 12 mg/L, 16 mg/L and 20 mg/L. The BAP concentration treatment showed a very significant different effect on the induction of A. commutatum tuna. The 8 mg/L BAP treatment showed the best results with the fastest initial explant response 10.8 dap, the highest number of shoots was 2 shoots/elplant, and the highest shoot was 0.75 cm.

Abstract

[ASSESING GROWTH AND STOMATAL DENSITY OF CULTIVATED SORGHUM PLANTS IN WETLAND ENVIRONMENTS ACROSS DIFFERENT IRRIGATION PATTERNS]. Sorghum cultivation is commonly associated with dry lands, but its potential for development on marginal swamp land remains limited. The wet conditions characteristic of swamp land pose a unique challenge to sorghum cultivation in Indonesia. This study sought to gather preliminary insights into sorghum crop development on swamp land by examining the effects of different irrigation patterns. Conducted at the Bengkulu University Greenhouse from June to August 2022, the research employed a group-randomized design with a single-factor pattern. Four irrigation treatments were administered: saturated water, saturated dry, dry-saturated, and dry. The experimental unit consisted of polybag planting media, repeated four times, with each polybag containing 20 seeds of the Numbu sorghum variety, cultivated until reaching six weeks of age. Irrigation patterns were simulated by placing the polybag media in basins filled with water up to a height of 10 cm. Results revealed varying impacts of irrigation patterns on sorghum growth, with water-saturated, dry-saturated, and dry-saturated patterns leading to superior growth compared to the dry pattern. Notably, sorghum plants cultivated under wet conditions on swamp land exhibited promising growth

Abstract

The synergistic effects of tuber cutting and PGR application on red onion growth and yield have not been extensively studied. Therefore, this study aimed to determine the most effective combination of tuber cutting and plant growth regulator (PGR) application for enhancing red onion growth and yield. Conducted between January and April 2023 in the greenhouse of the Agronomy Department, Faculty of Agriculture, University of Palangka Raya, the experiment utilized a completely randomized design (CRD) with seven treatments, each repeated five times. Treatments included: no cutting, cutting ¼ part of the bulb + 3 mL/L PGR, cutting ¼ part of the bulb + 6 mL/L PGR, cutting ¼ part of the bulb + 9 mL/L PGR, cutting ⅓ part of the bulb + 3 mL/L PGR, cutting ⅓ part of the bulb + 6 mL/L PGR, and cutting ⅓ part of the bulb + 9 mL/L PGR. Results indicate that red onion growth and yield can be significantly optimized through the strategic combination of tuber cutting and PGR application. The treatment involving cutting one-third of the tuber with 6 mL/L PGR concentration yielded the most favorable outcomes. Plants in this treatment displayed an average height of 45.84 cm, 51.4 leaves per plant, 10.6 bulbs per plant, 12.4 tillers per plant, a fresh weight of 42.79 g, a tuber dry weight of 18.34 g, and a bulb diameter of 2.18 cm. These findings suggest that cutting one-third of the bulb, in conjunction with specific PGR concentrations, enhances both yield and nutrient content in red onion bulbs, offering valuable insights for optimizing cultivation practices and maximizing crop productivity.

Abstract

Silica (Si) is a functional element in rice fields that is rarely studied, especially in Solok Regency. Intensive management without a fallow period causes silica to be transported out through high uptake by rice plants. This research aims to determine the distribution of available Si in the highland rice fields in Gunung Talang District, Solok Regency, West Sumatra. The research was carried out using a survey method. Soil samples were taken following the topo-sequence of the area of 600–1,100 meters above the sea level, which consists of 3 groups of rice fields based on height differences, namely the lower, middle, and upper fields. These rice fields have two types of straw management, namely burning and immersing. The research showed that the available Si content was 10.48–293.66 mg/kg  with an average of 133.34 mg/kg. The available Si content is higher in the upper paddy fields compared to the lower and middle paddy fields. Based on differences in straw management, the available Si content is lower in fields with straw buried compared to burned straw. The application of Si fertilizer is highly recommended to obtain the available Si content in the soil.

Abstract

[POTENTIAL OF BIOFERTILIZERS TO INCREASE RICE YIELD IN SWAMP LANDS] Nutrient unavailability is a major problem in swamp land due to flooded and acidic conditions. The use of biofertilizer, which can increase the availability of nutrients, is a solution to increase rice yields in swamp land. This research aimed to find out the improvement of the rice yield with an application of bacteria in biofertilizers in swampy land. One factor tested was the various doses of bacterial biofertilizer consisting of 1, 2, 3, and 4 g/50 g of paddy seeds, without bacteria as a control, arranged in a randomized block design with 3 replications. Rice seeds were soaked for 24 hours, then drained, and biofertilizer was applied as a seed treatment following the treatment doses. Seeding was carried out in trays measuring 15 cm high for 2 weeks. The inorganic fertilizer was applied at 75% of the recommended dose. The variables observed were plant height, number of tillers, number of productive tillers, percentage of empty grain, weight of 1000 seeds, and grain weight. The data observed were analyzed with an ANOVA at the 5% level and further tested with DMRT at the 5% level. The results showed that the bacteria in biological fertilizer can potentially increase the yield of swamp rice plants. A biofertilizer dosage of 4 g/50 g of seeds gave the highest yield in terms of grain weight per hill and per plot, as well as a weight of 1000 grains with an increase of yield of 14.32% compared to control.

Abstract

Floods can reduce soil quality because the entry of additional material which results in the loss of top soil due to the process of cleaning up flood residues in rice fields. The entry of mud deposits into rice fields can disrupt the balance of nutrients in the soil. This research aims to determine the relationship between the type of flood and the soil quality of coastal rice fields. The research method uses a purposive random sampling survey method.  After having laboratory soil analysis results, the data was then analyzed using Principal Component Analysis and Minimum Data Set. Sea water flood has a Soil Quality Index of 4.30 with good soil quality criteria, while for rice fields affected by river water flooding with an IKT value of 3.77 the soil quality is rather good and areas not affected by flooding have an IKT value of 4.71 with very good quality criteria. The results of the analysis show that the rice fields can be improved by managing rice fields affected by river and sea water flooding in a better way, such as using a good soil management system, using organic fertilizer and liming.

Abstract

[EXPLORATION AND PATHOGENICITY TEST OF Beauveria bassiana AGAINST ARMYWORMS (Spodoptera litura F.)]. Armyworm (Spodoptera litura) is a pest that can attack a variety of host plants. S. litura has a chewing bite mouth type and the phase that causes the most damage is instar 2, if no control is done then S. litura can cause damage up to 80% or cause crop failure. Control of S. litura still relies on chemical pesticides, this can have negative effects in the long term so alternative control is needed. Beauveria bassiana is an entomopathogenic fungus found in soil and has been studied to be able to control various types of insects at almost all stages of insects, including larvae and imago. The purpose of this study was to determine the effectiveness of B. bassiana fungus in controlling S. litura. The method used was the spore density level of 106, 107, 108 conidia/mL and the type of isolate B1 (isolate origin from Pacet) and B2 (isolate origin from Trawas), while the observation parameters were mortality rate and feeding rate. The results obtained were the treatment of isolate B1 at a spore density of 108 conidia/mL was able to cause the highest mortality of 80% while the rate of feeding power of isolate B1 treatment with a spore density of 108 conidia/mL was able to reduce the appetite of S. litura most effectively.

Abstract

[EVALUATION OF THE SUITABILITY OF LAND FOR THE DEVELOPMENT OF FOOD CROPS IN KARANGMALANG DISTRICT, SRAGEN REGENCY, CENTRAL JAVA]. Evaluation of land suitability was carried out in Karangmalang District to assess land suitability classes for food crops. This research was conducted to determine the limiting factors that result in a decrease in land productivity in the local area. The method used in this research was taking soil samples in 19 land map units based on the results of the base map overlay. Testing of soil samples includes soil texture characteristics, soil pH, organic C, CEC value, Base saturation value, available N content, available P2O5, and available K2O. The matching process is carried out using the SPKL application, then the results of the suitability of the selected land are displayed in map form using the Geographic Information System (GIS). The land suitability class is obtained in the marginal suitability class (S3) with the limiting factors of water availability (wa), oxygen availability (oa), and available nutrients (na). The dominant limiting factor found in all research test areas is rainfall and humidity which are classified as low to high. Improvement efforts that can be made to develop agricultural areas include creating irrigation channels to reduce excess water on the land, creating drainage channels to improve the condition of the drainage system, and applying fertilizer to increase the P2O5 and K2O content in the soil.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         ABSTRACT   [EVALUATION OF THE SUITABILITY OF LAND FOR THE DEVELOPMENT OF FOOD CROPS IN KARANGMALANG DISTRICT, SRAGEN DISTRICT, CENTRAL JAVA].
