Abstract

Sweet corn (Zea mays saccharata Sturt) cultivation can be done through variety selection technology use, fertilization, and the proper planting distance. One of the techniques used in sweet corn cultivation is planting distance and fertilization with NPK fertilizer. So, this study is critical in order to set the planting distance and NPK fertilizer dose to enhance sweet corn production. The goal of this study was to see how different planting distances and NPK fertilizer doses affected sweet corn production. The study was carried out in a rice field in Sambiroto Village, Padas District, at an elevation of ± 60 meters above sea level. It was conducted during January-May 2019. The method used was a factorial experiment with three replications based on a Randomized Block Design and two factors. The first factor is the planting distance, they are J1: 60 cm x 15 cm, J2: 60 cm x 20 cm, J3: 60 cm x 25 cm. The second factor is the NPK fertilizer dose, they are P0 = 0 kg / ha, P1 = 100 kg / ha, P2 = 200 kg / ha, P3 = 300 kg / ha. The results showed that (1) the J2 (60 x 20 cm) planting distance had the best effect on sweet corn cobs fresh weight per plant as well as per hectare without husks and sweet corn sugar content. (2) The NPK fertilizer dose of 300 kg/ha and planting distance of 60 x 20 cm resulted in optimal production on sugar content parameters. In conclusion, planting distance setting of 60 x 20 cm and NPK fertilizer dose of 300 kg / ha resulted in optimal production for sweet corn plant.

Abstract

Decreased mustard plant production is inseparable from the presence of plant pests and disease, one of which is Plutella xylostella. This pest can reduce the yield by 30-40%, even in some cases found to experience crop failure. Generally, in the community, controlling pests is using chemical pesticides. However, excessive use of chemical pesticides harms the environment and triggers health problems in humans, So, biological control is needed. One of them is an entomopathogenic nematode (NEP). Advantages Nematodes are environmentally friendly and are fast in crippling their host, but the multiplication of entomopathogenic nematodes encounters many obstacles, so research on these alternatives is needed. This research was carried out to determine the pathogenicity of entomopathogenic Nematodes cultured from the egg yolk media on Plutella xylostella larvae, then developed as an effective biocontrol. The pathogenicity test for Plutella xylostella larvae was performed using nine treatments placed in a factorial Completely Randomized Design (CRD) with each treatment repeated three times. The study indicate that the four bacterial isolates had the same ability to kill Plutella xylostella larvae during four days of observation, with the greatest percentage of 100 percent and the lowest percentage of 76.7 percent.

Abstract

Pollinating insects are referred as support services, namely services by the processes in the ecosystems that support human well-being by maintaining or enhancing ecosystem services. The availability of flowers, diversity, and behavior of visiting pollinator insects affect the effectiveness of pollination to increase the formation of fruit sets of mango plants. The purpose of this study is to observe the behavior of pollinator insects visiting the mango gadung clone 21 varieties and their effectiveness in increasing the formation of fruit sets. Research has been carried out on two flower seasons: March-May (Off season) and July-September (On season) 2020. Visiting behaviors observed were the number of visits per minute (foraging rate) and the length of visit per flower (flower handling time). Pollination effectiveness was measured from the number of fruit sets formed from the open flower panicles and confined with a tangerine gauze. The results of the study obtained seven species including Apis sp., Trigona sp., Xylocopa sp., Polistes sp. 1, Polistes sp. 2, Chrysomya sp., and Eristalis sp. Visits of pollinating insects on the highest number of mango panicle flowers were (31.69 ± 7.69) flowers / 60 seconds by Trigona sp insects, and the lowest numbers were (2.70 ± 0.67) flowers / 60 seconds by Eristalis sp. insects. The longest visits of pollinator insects on mango flowers were obtained by Eristalis sp for (25.3 ± 8.50) sec/individual/flower and the shortest visits were by Trigona sp for (1.8 ± 0.63) seconds/individual/flower. Insect pollination increases fruit formation by 267.5%. Keywords: insect visits, pollinating insects, fruit formation, gadung 21 varieties mango

Abstract

Biological control is a long-term and environmentally friendly method of pest management. The use of biological control agents has several advantages. These advantages include limiting the growth and development of plant-disrupting organisms over a relatively long period. Furthermore, biological agents have advantages in maintaining the equilibrium of the ecosystem that is present in agricultural environments. Due to their ability to create antimicrobials and stimulate plant development, as well as the fact that they are plant growth-promoting rhizobacteria (PGPR) and can survive in adverse environmental circumstances, antagonistic bacteria are one of the biological or biocontrol agents for managing illness. Antagonizing microorganisms can boost plant resilience to disease attack without polluting the environment or leaving toxic residues in the food chain Bacteria with good antagonistic agent properties can prevent the growth of pathogens and stimulate plant resistance responses. In addition, antagonistic bacteria can simultaneously boost the growth response of plants (plant growth promoter). One of the antagonistic bacteria used as PPGF is Pseudomonas fluorescens. Pseudomonas fluorescens has been widely recognized as having the potential as a biological agent to inhibit several plant pathogens. P. fluorescensis a group of root bacteria that effectively suppresses various plant diseases, including damping off of seedlings, soft rot, bacterial wilt, and others on many plant varieties. An antibiotic substance produced by P. fluorescens. (2,4-diacetylphloroglucinol/ 2,4-DAPG) can increase soil resistance to pathogens.

Abstract

From the conservation standpoint, critical land is land that can no longer function to operate the water system, soil resources, and biodiversity that lives on the land. Critical land exhibits signs indications of environmental degradation as a result of numerous sorts of improper land resource utilization. The impact of critical land results in a decrease in the function of conservation, production function, and socio-economic life of the community. The Sumadi Farmer Group encountered hurdles downstream (marketing) and upstream (cultivation) due to limited land use and lack of human resources who understood plant conservation systems. Therefore, this community service aims to preserve critical land with biological conservation methods by improving soil quality, cultivating healthy plants, and controlling pests and diseases using vegetable pesticides. The activity began with the observation of agroforestry planting land, then socialization and presentation of material by the team of lecturers, followed by demonstrations on the land, and ended with an evaluation. Empowered with an understanding of cultivation techniques and restorative plant care, the Sumadi farmer group is passionate about developing an organic farming system to overcome land issues
