Abstract

Trichoderma spp., is a fungus with the ability to control disease and promote plant growth. The mechanism is through the activity of microparasites, antimicrobial secondary metabolites, phytohormones and mobilization of plant nutrients for plant growth and production. The purpose of this study was to examine the biopolymer composition as a seedcoating formula on corn seeds with Trichoderma as the active ingredient, namely to obtain a biopolymer composition that is able to maintain viability and inactivate Trichoderma during storage. Completely randomized design was used with a single treatment factor for the composition of the formula, i.e.; K1 is control 1 (suspension of conidia Trichoderma sp.); K2 is xanthan gum 2.5% + Na alginate 2.5% + conidia suspension Trichoderma sp. + talk; K3 is xanthan gum 5% + Na alginate 5% + conidia suspension Trichoderma sp. + talk; K4 is xanthan gum 2.5% + CMC 2.5% + conidia suspension Trichoderma sp. + talk; K5 is xanthan gum 5% + CMC 5% + conidia suspension Trichoderma sp. + talk; K6 is Na alginate 2.5% + CMC 2.5% + Trichoderma sp. conidia suspension. + talk; K7 is Na alginate 5% + CMC 5% + conidia suspension Trichoderma sp. + talk; K8 is control 2 (suspension of conidia Trichoderma sp. + Talc). The results obtained showed that the composition of the seedcoating formula consisting of 5% xanthan gum + 5% Na alginate + Trichoderma conidia suspension + talc up to 60 days after application of seedcoting on seeds could inactivate Trichoderma reproduction, but could not suppress the decrease in viability.

Abstract

Spodoptera frugiperda J.E. Smith (Spodoptera: Noctuidae) is an invasive pests of maize that has been reported around the world. Control efforts using biological agents continue to be developed, including the use of entomopathogen bacteria such as Bacillus thuringiensis. To boost the efficacy and efficiency of biological control, formulations are required. The objective of this study was to develop biopesticide formulations and evaluate their efficacy. The research was carried out by formulating B. thuringiensis strain BtJ2 (1010 cfu mL -1) in liquid and paste formulations. The effectiveness of the formulations was evaluated using the feed dipping method. The results showed that paste formulations at a concentration of 10% caused 100% mortality, whereas the liquid formulation resulted in 85% mortality. The LC90 for the paste formulation was 6.66%, while the LC90 for the liquid formulation was 12.90%. Both the liquid and paste formulations had similar effects on mortality and viability. Based on the LC90 and LT90, the paste formulation was more efficient and faster in killing S. frugiperda than the liquid formulation. The results of this study provide recommendations that B. thuringiensis as a bioinsecticide is better formulated in a paste than in a liquid form.

Abstract

Downy mildew, caused by Peronosclerospora sp., is a major disease impacting maize (Zea mays L.) production, resulting in significant yield losses. This study evaluated the effectiveness of three Trichoderma sp.-based seed coating formulations (liquid, semi-solid, and powder) in reducing disease incidence and severity in maize. The experiment followed a completely randomized design with four treatments, including a control, replicated five times. The parameters assessed included disease incidence, severity, and control effectiveness over 35 days after inoculation. Results showed significant differences among treatments. The powder formulation (T3) demonstrated superior performance, reducing disease incidence by 42.3% and severity by 44.99% compared to the control (T0), which exhibited the highest disease levels. Control effectiveness of the T3 formulation reached 53.81%, categorized as moderately effective. The enhanced efficacy of the powder formulation is attributed to its ability to maintain high Trichoderma sp. populations, enabling sustained antagonistic activity through parasitism, antibiosis, and induced systemic resistance. These findings underline the potential of Trichoderma sp.-based seed coatings, particularly in powder form, as an environmentally friendly and practical alternative for managing downy mildew in maize.

Abstract

Inorganic fertilizer is believed to have a positive influence on the growth and production of corn plants, however, the scarcity of inorganic fertilizer and its impact on land resources needs to be reduced. Organic fertilizer is an alternative because its effect is positive but lasts for a long time. There are quite a lot of raw materials for organic fertilizer in Indonesia, including organic waste, grass, bushes and parts of vegetation that have not been utilized. Bamboo waste is one of the materials that can be used for liquid organic fertilizer (POC). The aim of this research is to analyze liquid organic fertilizer on soil acidity, nitrogen content, bacterial abundance, impact on chlorophyll and corn production. The method used in this research is an implementation study, treatment from 0 to 5 l/ha on 1 (one) hectare of land. Data analysis uses simple and descriptive regression equations. The research results showed that POC treatment could increase pH, N-total, bacterial abundance, leaf green color and seed weight of each plant compared to without POC treatment. POC treatment of 3 l/ha tends to result in an optimum increase in pH, total N and seed weight for each plant, while bacterial abundance is fluctuating

Abstract

Kegiatan sosialisasi, penyuluhan, dan implementasi teknologi pada demoplot bawang merah di Desa Sana Tengah, bertujuan untuk meningkatkan pengetahuan dan keterampilan petani dalam mengelola budidaya bawang merah. Sosialisasi yang melibatkan Kepala Desa, Ketua Gabungan Kelompok Tani, dan anggota Kelompok Tani Padimas, membahas topik-topik penting seperti pengendalian penyakit, pemilihan varietas sesuai kondisi agroklimat, serta penerapan teknologi baru seperti True Shallot Seed (TSS). Teknologi TSS diperkenalkan untuk mengatasi masalah penyediaan benih bawang merah yang terbatas dan meningkatkan ketahanan tanaman. Selain itu, pelatihan pengolahan pupuk organik dari limbah peternakan bertujuan untuk meningkatkan keberlanjutan usaha tani melalui sistem pertanian sirkular. Kegiatan monitoring dan evaluasi produksi menunjukkan peningkatan produktivitas bawang merah sebesar 1,56 ton/ha, meskipun masih berada di bawah rata-rata produktivitas nasional. Penanaman bawang merah di luar musim berhasil menurunkan intensitas serangan penyakit hingga 96.5%, meningkatkan kualitas umbi, dan membuka peluang untuk harga jual yang lebih baik. Hasil dari kegiatan ini diharapkan dapat mendorong perubahan perilaku petani, meningkatkan hasil pertanian, dan kesejahteraan petani, serta memberikan kontribusi pada pengembangan pertanian berkelanjutan di Desa Sana Tengah.

Abstract

This study aims to analyze and describe the internal factors among farmers, such as capital ownership, land area, farmer knowledge, the role of women farmers, and farming objectives, and how these affect the low interest in cultivating hybrid corn. Additionally, it examines external factors including production costs, cultivation techniques, availability and affordability of quality seeds, intensity of pest attacks, irrigation water needs, harvest period, product quality (color and taste), product shelf life, market opportunities, and selling price of hybrid corn. The findings of this study can serve as a basis for formulating future government or private sector programs to boost corn production in Pamekasan Regency, taking into account specific local conditions to support community welfare.
