Abstract

Waxi corn, which is included in the cereal plant group, is a food source for meeting the needs of life and has an important role in fulfilling community nutrition. Efforts to increase production that include quantity and quality can be made by applying NPK phonska fertilizer and spacing out planters to minimize the occurrence of competition. The study was to obtain the interaction caused by various doses of NPK phonska dose with different spacings on maize plants and to obtain the optimum dose of NPK phonska and ideal spacing to produce the optimum pulut maize plant. Using a factorial randomized block study design (RAKF)consisting of two treatment factors, each combination was repeated 3 times. Phoska NPK treatment consists of three levels (P1:50; P2:100 and P3:150)kg/ha, While the spacing treatment includes (J1: 50x 40; J2: 60x40 and J3: 70x40) cm.

Abstract

The armyworm Spodoptera frugiperda, which damages corn plants, is one of the invasive pests. The armyworm S. frugiperda damages corn plants by eating leaf tissue from one side so that the remaining epidermal tissue then makes holes in the leaves and eats from the edge of the leaf to the inside, which causes perforation in the leaves. Control efforts using insecticides have not been practical due to the feeding behaviour of the second and third instar larvae that settle on the inside of the leaves under protected conditions. Therefore, it is necessary to carry out other control techniques that can suppress the development of environmentally friendly S. frugiperda by considering economic and ecological aspects, namely biological control. Biological control optimizes the role of natural enemies as biological control agents in efforts to manage pest populations which are part of the chain in agroecosystems. Utilization of natural enemies, parasitoids, predators, and pathogen, can suppress the development of the S. frugiperda pest in corn, reducing the use of synthetic pesticides. Natural enemies of S. frugiperda include the egg parasitoid Telenomus sp. and Trichogramma sp.; larva parasitoid Glyptapanteles creatonoti (Viereck), solitary larval parasitoid Campoletis chlorideae Uchida, and parasitoid larvae of the order Hymenoptera: Ichneumonidae: Ichneumoninae and G. creatonoti. as well as an entomopathogenic species, Nomuraea rileyi (Farl.) Samson. Natural enemies can control S. frugiperda pests to save sustainable maize yields based on the basic principles of sustainable agriculture models. Agroecological steps are taken to reduce the population of S. frugiperda in corn plants by:/ (1) sustainable management of soil fertility, primarily actions that maintain or store soil organic carbon; (2) intercropping with properly selected companion plants; and (3) diversification of the agricultural environment through the management of (semi) natural habitats at various spatial scales.

Abstract

Arbuscular mycorrhiza fungi (FMA) can be found in almost all types of soil. FMA symbiosis can increase plant growth, water absorption, and nutrients such as nitrogen, phosphorus, and other micronutrients. It also can increase resistance to water stress, reduce the level of pathogenic attacks and increase growth booster hormones. The purpose of this study was to identify the type of FMA in several areas of plantation and horticultural crops in Pemo Village. The results showed that a total of 1004 spores were found consisting of two types of FMA, namely the genus of glomus as many as 788 spores, and 216 spores from the genus acaulospora. The planting area that has the highest number of spores is horticultural planting, which is 336 spores. Characteristics of dominant dominant spores of oval and brown.

Abstract

The growing weeds in cassava plants are unwanted because it negatively inhibits growth and reduces tuber production in cassava. This research aims to determine differences in the types and populations of weeds in the treated and fallow soil treatment. This study used the proportion sampling method by calculating the number of weed species found in cassava plantations, separating each weed found according to the plot, identifying the types of weeds obtained, and recording the data in a table of the number and density of weeds. This research shows that the population and types of weeds have different amounts between the treated land treated and the treated fallow land. The highest weed population was found at the treatment of fallow land with clover weed (Trifolium repens) of 1,462. In the tillage treatment, the highest weed population yield was found in the bandotan weed (Ageraum conyzoides) with a total population of 269. Based on observations, cassava plants on processed land had better development compared to cassava development on fallow land treatment.

Abstract

The golden snail is a pest originating from the American continent and entering Asia as a food ingredient. Initially, these animals were used as ornamental animals and joined the rice fields through waterways. Even the golden snail is one of the main pests that attack rice plants. Utilization of gadung tuber is an alternative to controlling golden snails considering the abundant presence of gadung tuber and its toxic cyanide content. This study aims to determine the ability of gadung tuber extract to control golden snail pests, the concentration of gadung tuber extract is the best in controlling golden snail pests. The research method was arranged in a randomized block design, with 4 repetitions and 5 treatments at the yam tuber extract level, namely, G0 (0 g/5 l), G1 (3 g/5 l), G2 (6 g/5 l), G3 ( 9 g/5 l) and G4 (12 g/5 l). The application of gadung tuber extract was carried out 2 times, namely on rice plants aged 7 hst and 18 hst which were given by spraying on each research plot in the morning at 07.00-Wita. The results of the study showed that gadung tuber extract had activity as a contact, stomach, and systemic poison with the best dose being 3 grams/5 liters

Abstract

Among the community, bamboo is well known for its excellent utilization, starting from its sturdy, resilient, straight stems, which are easy to split, work with, and shape. In addition, the price of bamboo is cheaper and easily found in residential areas. One of the bamboo-producing areas found in the West Nusa Tenggara region is the Aik Bual Village HKm. It is known that research related to the physical properties of bamboo has not been carried out in the area. Physical properties become a benchmark in seeing cracks and breaks in bamboo caused by high water content and low specific gravity. This study aims to review the four types of bamboo in the Aik Bual HKm area against the influence of axial direction, the presence of books and internodes, moisture content and specific gravity. Fresh water content of petung bamboo, ampel bamboo, string bamboo, galah bamboo: 90,19%; 102,72%; 122,70%; 138,95%. Air dry moisture content of petung bamboo, ampel bamboo, string bamboo, galah bamboo: 12,31%; 13,80%; 12,27%; 11,95. Fresh specific gravity of petung bamboo, ampel bamboo, string bamboo, galah bamboo: 0,63; 0,58; 0,52; 0,49. Air dry specific gravity of petung bamboo, ampel bamboo, string bamboo, galah bamboo: 0,70; 0,71; 0,57; 0,61. Furnace dry specific gravity of petung bamboo, ampel bamboo, string bamboo, galah bamboo as follows: 0,72; 0,70; 0,62; 0,59. Of the four types of bamboo used, it is known that the axial direction, the presence of books and internodes do not have a significant effect on the moisture content and specific gravity.
