Efforts to increase garlic productivity can be achieved through cultivation innovations, such as selecting the appropriate tuber size and incorporating organic matter. This study aimed to determine the optimal combination of tuber size and organic matter to increase garlic yield. The research was arranged using a Split Plot Design (SPD) within a Randomized Block Design, with three replications. The main plots involved organic matter treatments: (1) no organic matter, (2) biochar (1 kg/m²), (3) biochar + manure (0.5 kg/m²:0.5 kg/m²), and (4) manure (1 kg/m²). The subplots consisted of tuber size categories: (1) small tubers (0.3-0.6 g), (2) medium tubers (0.7-1 g), and (3) large tubers (1.1-1.4 g). Results showed an interaction between large tuber sizes and the addition of manure, which produced the highest fresh bulb weight. Additionally, the combination of large tuber sizes with the addition of biochar and manure resulted in a high dry bulb weight. Keywords: Biochar, Manure, Nutrient, Production.

This research aims to determine the effect of concentrations of Paklobutrazol and SP-36 fertilizer on the growth of peanut plants (Arachis hypogaea L.). This research was carried out in October 2023 – January 2024 at the Dsn Baban Barat Land in Blega Bangkalan, East Java. This research is a factorial experiment which was prepared using a Completely Randomized Design (CRD) with 3 replications. The first factor is the provision of Paklobutrazol ZPT and the second factor is using SP-36 fertilizer Factor I: Paclobutrazol (P) concentration which consists of 4 levels: P0 = 0 ppm, P1 = 100 ppm, P2 = 200 ppm, P3 = 300 ppm and Fakor II = SP-36 fertilizer dose consisting of 3 levels: S0 = 150 kg/ha, S1 = 200 kg/ha, S2 = 250 kg/ha. The parameters observed were plant height, number of leaves (strands), age at flower emergence, number of pods planted, number of filled and empty pods, weight of pods planted, weight of seeds planted. The research results showed that the Paklobutrazol concentration treatment gave a positive response to the specified parameters, including plant height, number of leaves (strands), age at flower emergence, number of pods planted, number of filled and empty pods, weight of pods planted, weight of seeds planted. The highest average yield of pod weight per plant was in the P1 concentration treatment, namely 100 ppm (33.78 gr). The Paklobutrazol concentration treatment also produced a very significant effect on seed weight per plant. The highest was in the P1 concentration treatment, namely 100 ppm 28.50 gr. The SP-36 fertilizer dose treatment had a significant effect on the number of pods, the weight of the pods planted and the weight of the seeds planted. However, the parameters of plant height, number of leaves (strands), age at flower emergence, number of filled and empty pods, had no real influence. The results of the combined data analysis from both gave a positive response to observations of the number of pods, the weight of the pods planted and the weight of the seeds planted.

Kurangnya ketersediaan bibit unggul yang mengakibatkan tidak terpenuhinya minat masyarakat akan jambu air Dalhari. Perbanyakan vegetatif secara okluasi tidak dapat memberikan hasil yang efektif karena tidak dapat dilakukan dalam jumlah besar. Solusi yang dapat dilakukan yaitu dengan menerapkan metode setek batang sebagai salah satu alternatif dalam perbanyakan vegetatif tanaman jambu air. Penelitian ini bertujuan untuk mengetahui interaksi kombinasi antara jenis zat pengatur tumbuh dan bahan setek terhadap pertumbuhan awal setek jambu air dalhari. Penelitian ini disusun menggunakan metode Rancangan Acak Lengkap Faktorial (RALF) dengan 2 faktor yaitu jenis ZPT (tanpa ZPT/kontrol, rootone-f, ekstrak bawang merah, ekstrak tauge dan ekstrak lidah buaya) dan bahan setek (batang atas, batang tengah dan batang bawah). Hasil penelitian menunjukkan adanya inetaksi pada kombinasi tanpa ZPT dan batang bawah terhadap rerata jumlah tunas. Pada perlakuan tunggal beberapa perlakuan memberikan hasil yang lebih baik terhadap parameter yang diujikan, tetapi ada beberapa perlakuan yang tidak memberikan pengaruh sama sekali.

Pakcoy (Brassica rapa L.) is one of the important and popular vegetable crops in Indonesia. City development and massive urbanization have resulted in the shrinking of agricultural land in urban areas. Home gardens have great potential if managed optimally and planned. Therefore, the concept of urban farming with the vertical farming method can be a solution. This study aimed to determine the optimal composition of planting media and liquid organic fertilizer (LOF) concentration for the growth and production of pakcoy plants. This study used a completely randomized design (CRD) with two factors. The first factor was the composition of the planting medium, which consisted of three levels: soil, compost, and goat manure with a ratio of 1:1:1, 1:1:2, and 1:2:1. The second factor was the concentration of LOF and urea, which consisted of four levels: 1 gram urea, 2 ml/liter water, 4 ml/liter water, and 6 ml/liter water. The results of the study showed that the combination of planting medium composition and LOF concentration had an effect on all observation parameters. The combination of planting medium composition 1:1:2 and LOF concentration of 4 ml/liter water produced the best results for all observation parameters, namely plant height, number of leaves, total fresh weight, fresh head weight, fresh root weight, and plant dry weight. Key words : Pakcoy mustard, verticulture, media composition, concentration, LOF

Background: Corn (Zea mays L.) is the most essential food commodity after rice and a secondary crop. The demand for Corn in Indonesia is currently relatively high, yet its production has been declining. To increase Corn production, improvements in cultivation techniques are necessary. One such method is optimizing assimilate distribution through leaf defoliation, as well as creating optimal growing conditions through fertilization. Fertilization should be balanced by using both inorganic and organic fertilizers. In this study, NPK Phonska and Guano fertilizers were used. Methods: This study employed a factorial randomized complete block design (RCBD) with two factors. The first factor was the level of leaf defoliation below the cob, consisting of three levels: no defoliation (D1), defoliation leaving three leaves (D2), and defoliation leaving two leaves (D3). The second factor was the substitution of NPK Phonska and guano fertilizers with five levels: 100% NPK Phonska (P1), 75% NPK Phonska + 25% Guano (P2), 50% NPK Phonska + 50% Guano (P3), 25% NPK Phonska + 75% Guano (P4), and 100% Guano (P5). Results: The study's results showed that defoliation, leaving two leaves below the cob, combined with the application of 7 tons/ha of guano fertilizer without the addition of NPK, increased cob weight, cob length, and dry kernel weight per plant. Additionally, the independent application of 7 tons/ha of guano fertilizer without NPK Phonska significantly increased cob diameter. Conclusions: The combination treatment of defoliation, leaving two leaves below the cob, and the application of 7 tons/ha of guano fertilizer without the addition of NPK had the most favorable effect on Corn production.

Aeroponics is cultivation that can produce lettuce optimally. This research aims to obtain the quality and quantity of lettuce using the vertical hexagonal aeroponics method with the influence of planting direction, sunlight and the addition of liquid organic fertilizer. This research used a factorial Randomized Group Design (RAK) and was repeated three times. The first factor is the Ab mix concentration and the second factor is the planting direction. The lettuce yield variables observed were plant length, number of leaves, harvest yield (root length, wet weight, dry weight) and organoleptic tests. The single factor of adding POC to nutrients influenced the variables wet weight, dry weight and root length, whereas the planting direction treatment only affected root length and the interaction of planting direction treatment and adding POC to nutrients affected organoleptic and stem variables. long. The root length parameters of 58.94 cm, wet weight of 90.59 grams, and dry weight of 8.40 grams are the best parameters if POC is added to nutrition, and treatment of northeastern plantings gives the highest root length, namely 68.73 cm.
