Corn is one of the most important food commodities consumed by most people in various parts of the country. There is a real interaction between spacing varieties on the observed characters. There are one or more production chatacters that have a significant correlation with production. This research will be carried out at the Experimental Garden of the Bajeng Cereal Research Institute, Bajeng District, Gowa Regency, South Sulawesi, with a coordinate point of 5o18'21.5 "LS, 119o28'38.6" BT. The research was conducted from August to November 2020. This study used a separate plot experimental design. The main plot is a planting system legowo (S) which consists of 3 planting systems, namely the spacing of 75 x 20 cm = 66,667 pop / ha (J1), Legowo (50 + 100) x 20 cm = 66,667 population / ha (J2), and Legowo (50 + 100) x 18 cm = 74,074 population / ha (J3). Meanwhile, the subplots were maize varieties (V), namely NASA 29 (V1), Bisi 2 (V2), and Sinhas 1 (V3). From the research results, it can be concluded that the spacing has no effect on the character of the observation. the variety has a very significant effect on the observed character, except for rod diameter. As for the correlation, the observed characters that had an effect on production were ear length and weight of 1000 seeds

The purpose of this study was to determine the effect of biofertilizer application based on the types and spraying frequencies on the yield components of maize variety SINHAS 1. The research was conducted in Tarowang Village, Galesong Selatan District, Takalar Regency from August to November 2020. Three types of biofertilizer were used applied in five different frequencies of spraying. The study employed a split plot design with types of biofertilizer as the main plot and application frequencies as the sub plots. The research was repeated 3 times, resulted in a total of 45 experimental units. The maize variety used was SINHAS 1 and observations were made on the yield components of the ear height, wet weight of peeled cobs, ear length and diameter, percentage of seed yield, weight of 1000 seeds at 15% moisture content, and productivity. The results shows that the frequency of biofertilizer application had more dominant effect than the type of biofertilizer. The type of biofertilizer used has relatively the same role in the growth of the yield components of SINHAS 1 corn. Based on the results, it is recommended to apply the biofertilizer in four times in fertilizing the SINHAS 1 maize crop

Productivity of superior genotypes often did not satisfyingly achieve its genetic yield potential. Interaction between genetics and environmental factors more likely to driven the final yield of the varieties. The concept of balanced fertilization is carried out by referring to the creation of a balance of macro-nutrients in the soil so that plants can produce optimally. The research was conducted in a form of experimental study at Tarowang village, Takalar Regency during growing season of 2021 from May to September 2021. A split plot design was used with fertilization package as the main plot and superior varieties as subplots. Three fertilization packages combined inorganic and organic fertilizer were used, namely fertilization package consisted of N: P: K with ratio of 225:100:75, fertilizer package that consisted of N: P: K ratio of 200:100:50 + KNO3 25 kg + Biotani 5cc L-1, and fertilizer package that consisted of N: P: K with a ratio of 200:100:50 + KNO3 25 kg + Ecofarming 5cc L-1. Six superior varieties used were Nasa 29, JH-37, Bisi 2, Bisi 18, SINHAS 1 and NK7328. Based on the level of both factors, 18 treatment combinations were obtained and repeated three times. Responses of maize varieties to fertilization packages, consisted of different combination and dosage of NPK fertilizers, KNO3 and organic fertilizers, were varied between varieties. The treatment of fertilization package of N: P: K = 225:100:75 with Bisi 2 variety gave the highest maize productivity, namely 12.39ton ha-1

Drought causes hampered nutrient absorption and water uptake in plants hence abnormal growth and lower yield. One of alternative solutions is the development of maize varieties tolerant to drought stress through plant breeding. This study aims to find superior M3 mutant genotypes of maize that can adapt to dry land with high productivity. The study was conducted in green house of the Faculty of Agriculture, Universitas Hasanuddin using Split Plot Design. Water availability level was set as main plot consisted of 60%, 80% and 100% and maize mutant was set as subplot consisted of four M3 mutants, namely Bisma 100 gy, Bisma 200 gy, Lamuru 100 gy, and Lamuru 200 gy. In addition two varieties were used as controls ie. Bisma, and Lamuru resulted in total of 6 genotypes tested in the study. Mutant genotype of Bisma 200 gy showed tolerance to all water availability levels and significantly differed to other mutants including its parents indicated with higher yield. 100% water availability condition resulted in higher production than the other two water availability conditions with the average yield produced was 44.1 g per plant

Saat ini pemerintah Kota Makassar menggalakkan program urban farming bagi masyarakat di tingkat RT/RW di setiap kelurahan. Program tersebut bertujuan untuk meningkatkan ketahanan pangan masyarakat secara mandiri. Kelompok Wanita Tani (KWT) yang terbentuk di setiap kelurahan juga diminta berperan aktif menghasilkan produk-produk pertanian seperti sayur-sayuran dan buah-buahan. Namun, tanah-tanah di perkotaan umumnya tidak subur karena aktivitas manusia, timbunan bahan bangunan, dan cemaran-cemaran lain dari limbah rumah tangga, industri, rumah sakit, dan pabrik-pabrik. Media tumbuh DAENGKU menawarkan solusi tepat bagi penggiat pertanian perkotaan untuk meningkatkan kesuburan tanah perkotaan. Selain itu, dengan semakin sulitnya ketersediaan tanah subur di perkotaan, maka DAENGKU diharapkan mampu menyediakan media tumbuh yang baik dan memberikan keuntungan ekonomi bagi mitra. Kegiatan Program Pengabdian kepada Masyarakat UNHAS-Program Pengembangan Usaha Produk Intelektual Kampus (PPMU-PPUPIK) ini bertujuan meningkatkan pengetahuan, wawasan, dan keterampilan mitra mengelola dan menghasilkan media tanam DAENGKU. Kegiatan pengabdian ini berlangsung sejak April-Juni 2026 di KWT Selasih, Kelurahan Bangkala, Kecamatan Manggala, Kota Makassar. Kegiatan ini berhasil meningkatkan pengetahuan dan keterampilan mitra sasaran tentang pengelolaan limbah organik dan eceng gondok dengan teknologi mikroba biodekomposer. Hasil pre-post test menunjukkan lebih 85% dari anggota KWT mengalami peningkatan wawasan dan pengetahuan terkait kegiatan ini. Selain itu, KWT Selasih juga telah berhasil memproduksi dan menjual DAENGKU di toko-toko pertanian, pameran, dan online sekitar 500-600 kg per bulan. Informasi kegiatan ini juga telah tersebar melalui media online dan kanal Youtube Fakultas Pertanian. Kata kunci: Kelompok Wanita Tani, Kompos, Mikroba, Pertanian perkotaan, Sayuran. ABSTRACT The Makassar City government is currently promoting urban farming programs for residents at the neighborhood (RT/RW) level in every urban village (*kelurahan*). These programs aim to enhance community food security through self-reliance. Women Farmers' Groups (KWT) established in each village are also encouraged to play an active role in producing agricultural goods such as vegetables and fruits. However, urban soil is generally infertile due to human activity, construction debris, and contamination from household, industrial, hospital, and factory waste. DAENGKU growing medium offers an ideal solution for urban farming enthusiasts looking to improve urban soil fertility. Furthermore, given the increasing scarcity of fertile urban land, DAENGKU is expected to provide a high-quality growing medium while generating economic benefits for its partners. This UNHAS Community Service and Campus Intellectual Product Business Development Program (PPMU-PPUPIK) aimed to enhance the knowledge, insight, and skills of partners in managing and producing the DAENGKU growing medium. The program was conducted from April to June 2026 with the Selasih Women Farmers' Group (KWT) in Bangkala Village, Manggala District, Makassar City. The initiative successfully improved the target partners' knowledge and skills regarding the management of organic waste and water hyacinth using microbial biodecomposer technology. Pre- and post-test results indicated that over 85% of KWT members gained increased insight and knowledge related to the program. Additionally, KWT Selasih has successfully produced and sold DAENGKU—through agricultural shops, exhibitions, and online channels—at a volume of approximately 500–600 kg per month. Information regarding this program has also been disseminated via online media and the Faculty of Agriculture's YouTube channel. Keywords: Compost, Microbe, Urban farming, Vegetables, Women Farmer Groups.
