Abstract Plant characteristics, genetic diversity, and heritability are some of the factors that influence rice growth and production. This study aims to determine the physical characteristics and the relationship between genotype variants, heritability tests, and genetic progress that can contribute to rice production in lowland irrigated rice fields. This study was conducted from October 2022 to March 2023 in North Buton Regency, Southeast Sulawesi. The design used in this study was a Randomized Block Design with 7 varieties and 3 replications. The research data were analyzed based on the procedures of variance, genetic variance, heritability, agromorphological characteristics, partial correlation, and cross tests. The results obtained showed that the highest plant height characteristics were found in Ciherang (110 cm), the highest plant age was found in Ciherang (120 days). The characteristics of the 7 varieties tested, lodging properties, 57.14% were somewhat resistant to lodging and 42.86% were resistant to lodging. Pest resistance properties, tungro resistance (8.04%), resistance to brown planthopper (57.14%), and resistance to leaf blight (85.71%). Furthermore, regarding the correlation relationship, dry grain yield is positively correlated with the number of productive tillers, plant height, panicle length, grain weight, number of empty grains, full grains, and weight per 1000 grains. The genetic variation values of plant height, number of panicles, grain weight, and weight per 1000 grains are higher in the Inpari-7, Inpari-11, Inpari-13, Inpari-14, Inpari-15, Inpari-20 varieties. The highest dry grain yield is found in Inpari-13, Inpari-15, and Inpari20 compared to Ciherang. Keywords: Rice variety, Low land rice, Characteristics, Genetic diversity, Heritability, Grain yield

Abstract. The selection of superior maize varieties and appropriate planting arrangements plays a crucial role in improving crop productivity and managing pest infestations. Spodoptera frugiperda (fall armyworm) is a major pest in maize cultivation, while natural predators such as Oecophylla smaragdina (weaver ants) offer potential for biological control. This study aimed to examine the effects of two planting models and seven maize varieties on agronomic traits, grain yield, pest damage, and predator abundance. A split-plot randomized block design was implemented with three replications. The main plots consisted of two planting arrangements: the conventional tile pattern (70 cm × 40 cm) and the legowo 2:1 system ((50 cm × 35 cm) × 90 cm). Sub-plots included seven maize varieties: Srikandi Kuning, Pulut Uri, Provit A1, Anoman, Srikandi Ungu, Bisma, and Sukmaraga, each grown in 150 m2 plots. Results showed significant varietal differences in plant height (168.78 -219.30 cm), leaf area (6.60 -7.85 cm²), flowering time (45.33 -49.00 days), and ear height (89.42 -119.32 cm). The legowo 2:1 planting model significantly increased grain yield (7.89 t ha−1) compared to the tile model (5.38 t ha−1 and reduced leaf (19.12% vs. 21.26%) and cob damage (11.58% vs. 13.09%) by S. frugiperda. Larval density varied among varieties, with Bisma showing the lowest incidence (0.43 larvae per plant; 12.32% leaf damage, 8.80% cob damage) and Sukmaraga the highest (1.23 larvae per plant; 25.23% leaf, 15.03% cob damage). Weaver ant abundance was negatively correlated with pest population and damage intensity. Biplot analysis indicated that Bisma performed best under the legowo system, while Anoman showed optimal performance under the tile model. These findings suggest that integrating the appropriate planting configuration with resistant maize varieties can enhance productivity and reduce pest damage, offering valuable strategies for sustainable maize cultivation.

Abstract. The types of pests that reduce rice grain yields are the rat R. argentiventer and the rice pest S. innotata. This chapter aims to provide information on technology to control rats and white rice stem borers effectively, efficiently, and environmentally friendly. The results of the study showed that the most effective control of S. innotata pests using botanical insecticides was the use of neem seed extract and yam bean seeds with a rice damage rate of around 13.4% and lower than the control which reached 15.24–19.05% in the vegetative phase and the generative phase only reached 9.36% and 11.41% and much lower than the control (20.00%). The most effective and environmentally friendly rat pest control technology is the use of the Trap Barrier System (TBS) and the Linear Trap Barrier System (LTBS), which can reduce the rat population by around 25–65%. Rat pest control with eagle predators (Tyto alba) can reduce the level of damage to rice plants due to rat pest attacks by around 2-5 rats per day.

Abstract. Several factors that significantly affect the reproduction of powder post beetles were food, moisture content, temperature, humidity, light, air/aeration, and the presence of natural enemies. This paper reviews the environment of the components that affect the reproduction of the powder post beetles Sitophilus zeamasi Motsch. Carbohydrates (sucrose and fructose) are the most significant energy source for the reproductive system and life span. In contrast, proteins consisting of amino acids such as arginine, lysine, leucine, isoleucine, tryptophan, histidine, phenylalanine, methionine, valine, and threonine, as well as components of fat, fatty acids, and sterols, are needed by insects for their energy supply and wing growth. The development of the powder post beetle population is rapid if the moisture content of the stored material is more than 15%. Temperature is also very influential on the reproduction of powder post beetles. The optimum humidity for this pest is around 75%. The next component is light, whereas light (dark and bright conditions) affects insect behavior in choosing food and reproducing (copulation and laying eggs). Another component is oxygen, whereby oxygen levels in the air must be more than 2%. If the CO2 level in the storage room is above 40%, then the pest in all stages will perish.

Abstract: The maize weevil is corn pests that reduce production and damages the storage quality. Therefore, pest management should simultaneously be carried out by applying all available technologies. This pest can damage up to 30% of plant productivity, not including the value of losses due to decreased quality of hazardous materials for health and safety, both as feed and feed. Aflatoxin contamination for example, can be dangerous if consumed. This paper is a desk study that reviews some literature, attempts to describe the role of cultivation technology improvement, crop protection, optimum watering, phosphate fertilization, the technology of postharvest handling, management of water content of corn kernels, sanitation, cleanliness, warehouse management, pesticide use, and fumigation in reducing the scale of damage and increasing the added value of production, and improving the quality of stored materials so that they are safe to use, both as food and feed. The utilization of cultivation technology management and good postharvest handling will have an impact on controlling and reducing the damage quality of storage materials and increasing the safe product quality for both food and feed needs as well.

Abstract. The use of natural enemies can reduce the application of insecticides which have a negative influence on ecosystems and human health. The objective of this study is to inventory the insitu of the natural enemies in corn crops that found in the experimental station of Indonesian Cereals Research Institute (Balitsereal) in Maros, South Sulawesi. The observation plot used three replications by taking a sample of 30 plants for each replication, with a total plant observation of 90 units per block. The number of natural enemy populations obtained was recorded by counting the number of natural enemies to find out the total average number of natural enemy populations contained in the observation plot. The results showed that there were 11 types of natural enemies in corn crops namely Harmonia octomaculata (lady beetle), Menochilus sexmaculatus (lady beetle), Ophionea nigrofasciata (Schmidt-Goebel) (ground beetle), Cyrtorhinus lividipennis Reuter (plant bug), Panstenon nr. Collaris Boucek (wasp), Araneus inustus (orb spider), Cardiochiles philippinensis (wasp), Phanerotoma sp. (wasp), Pipunculus mutillatus (big-headed fly), Harpalus pensylvanicus and Chrysoperla carnea (Stephens). The existance of the above natural enemies will be very usefull in decreasing the pesticide application in the fields.

Nurnina Nonci | Endang GatiLestari | Amran Muis | Syafruddin | Sri Wahyuni | Surianto Sipi |Ramlah Arief | M. SudjakSaenong | Ahmad Muliadi

This study aimed to determine the effect of storage duration on sorghum seed quality, specifically focusing on weight loss and storage pest infestation, under laboratory conditions. Eight different sorghum cultivars (Kawali, Numbu, Suri 4, Super 1, Soper 6, Bioguma 1, Bioguma 2 and Bioguma 3) were tested, each with an initial moisture content of 12%. The experiment used a completely randomised design with five replications for each cultivar. Observations for weight loss and seed damage were performed at 1, 2 and 3 months of storage. Proximate analysis was also conducted to determine the ash, protein, fat and fibre content of the sorghum cultivars. All tested sorghum cultivars demonstrated slightly moderate tolerance for up to 3 months of storage, although some experienced increased weight loss during this period. The pest species responsible for damage to stored sorghum seeds was identified as Sitophilus oryzae. Significant correlations were found between weight loss and damaged seeds, damaged seeds and crude fibre content, weight loss and crude fat content, weight loss and crude fibre content, and ash and crude protein content. This study shows that while sorghum cultivars generally exhibit slightly moderate tolerance for up to 3 months of storage, they are susceptible to damage from S. oryzae. The research also identified key compositional factors, such as fibre and fat content, that influence seed damage and weight loss during storage.
