Biochar is an organic material instantly made by burning wood into charcoal by pyrolysis, which can meet the high demand for an organic material that cannot be available in a short time. The study aimed to determine the effect of biochar and Chromolaena odorata liquid fertilizer (CLF) enriched with Sodium bicarbonate on soil pH and Muskmelon (Cucumis melo L.) productivity. The research was conducted from December to February 2019 at the field station of Tamansiswa University, Padang. The study was carried out in a factorial experiment with 2 treatment factors arranged in a Completely Randomized Design, consisting of three replications within treatments. The data obtained were analyzed using the F test at 5%, followed by the Least Significant Difference (LSD) test at 5%. The results showed that there was an interaction effect of Biochar and CLF application on reducing the soil pH. Among all treatments, the application of 2 t.Ha-1 biochar combined with 50 ml.L-1 CLF + 0 g.L-1 sodium bicarbonate resulted in the highest growth rate and yield of muskmelon in Ultisols soil.

Garlic (Allium sativum L.) is one of the important commodities in the horticultural sub-sector which is one of the basic needs of the community that must be fulfilled. However, garlic production in Indonesia has not been able to meet the demands of society's needs. For this reason, an additional area of land for garlic development is aimed at the optimal suitability of environmental physical factors. The use of superior varieties is one of the technologies that play a role in increasing the productivity of garlic. This research was conducted in May - August 2020 in Tarusan and Muaro Aie Bayang Utara, Pesisir Selatan Regency, West Sumatra Province with a randomized block design using Lumbu Hijau, Lumbu Kuning and local varieties of Bukik Sileh Solok as treatment. The results showed that the varieties of Lumbu Kuning and Lumbu Hijau were able to adapt well in Muaro Aie with an altitude of 322 masl compared to Tarusan with an altitude of 4 masl. Both varieties gave a fairly good growth response and yield, although only half of the description of these varieties.

Sunflower is one of the oil-producing plants that potentially can be developed as a food raw material, industrial, medicine, and cosmetics. Sunflower cultivation needs to be conducted in various lands in Indonesia; one of them is coastal regions. However, on one side, these lands were included on marginal land because the high level of salinity constrains it. This research aims to determine sunflower growth and thrive on salinity stress in the coastal land. This research applies a random group design with five treatments consisting of two accession and three sunflower varieties with three repetitions. The research result shows that the sunflower accession Ha1 growth and thrive on salinity stress in coastal land was quite significant compared to the accession Ha15 and Kanigara, Helina IPB, and BM1 IPB varieties. Generally, sunflower can adapt to stress salinity in coastal land.

Garlic is one of the agricultural commodities needed by people in Indonesia. The productivity of local garlic produced is still low due to the limited availability of seed tubers and the non-uniform quality of tubers. Production and quality of garlic seed bulbs can be increased through the shelf life of bulbs at low temperatures by tissue culture techniques. This study aimed to determine the effect of the shelf life of tubers at low temperatures and the composition of growth regulators on garlic shoot induction. The design used was a randomized block design for two treatment factors and 15 replications. The first factor was the shelf life of tubers at low temperatures, which consisted of 4 treatments, namely 0, 10, 20, and 30 days. The second factor is the composition of growth regulators consisting of: 2.0 ppm Kinetin + 0.4 ppm 2.4-D; 2.0 ppm NAA + 2.0 ppm BAP; 0.5 ppm NAA + 2.0 ppm 2ip; and 0.2 ppm NAA + 2.25 ppm BAP. The results obtained from this study were that the shelf life of 0 days with the composition of ZPT 2 ppm NAA + 2 ppm BAP, and shelf life of 10 days 0.5 ppm NAA + 2.25 ppm BAP affected shoot emergence time, the number of explants sprouted, and percentage of explants sprouted.

ABSTRACT The aim of this study were (1) to determine the effect of rice husk biochar and rice straw compost on growth and production rice (Oryza sativa) and (2) to determine the ability of rice husk biochar and rice straw compost in providing nutrients to Ultisol. The research was carried out February – July 2018 in Sungai Abang Village, Lubuk Alung Regency, Padang Pariaman. Research applied Random Group Design with 5 treatment : 0% Rice husk biochar + 0% Rice straw compost, 100% Rice husk biochar + 0% Rice straw compost, 75% Rice husk biochar + 25% Rice straw compost, 50% Biochar rice husk + 50% Rice straw compost and 25% Rice husk biochar + 75% Rice straw compost. Observations were made on soil and crops including initial soil analyzes ie before treatment was given, soil analysis after incubation, and final soil analysis (pH, N-total, P-available, K-dd, Ca-dd, Mg-dd and Sulfur) and plant observations include plant height, the productive of tiller, total of tiller and weight of grain per hectare. From the research that has been done can be concluded (1) the use of rice husk biochar and rice straw compost affect the growth and production of rice plants seen in the treatment of 75% rice husk biochar + 25% Rice Straw rice husk biochar with the number of productive tillers of 29 tillers and production of rice plants as much as 8,238 tons / ha and (2) the use of rice husk biochar and rice straw compost is able to provide nutrients in Ultisol indicated by increasing pH, N, P, K, Ca, Mg and S.

SMA Negeri 13 Padang is one of the high schools in Padang, which has been the partner of the Faculty of Agriculture, Andalas University. Currently, the school is experiencing difficulties in developing the Adiwiyata program. The less than optimal use of the schoolyard becomes an obstacle in realizing this program. The vertical garden is a solution that can be applied in schools so that the yard's utilization can be done optimally. This activity aims to provide knowledge and understanding of the school regarding the vertical garden. This activity was carried out at SMA Negeri 13 Padang using survey methods, counseling, and demonstrations in making a vertical garden. Based on the activities carried out, the results obtained are 16% of the participants know about the vertical garden, and 84% of the participants do not learn the vertical garden technique yet. In the end of program, 80% of the participants understood the vertical garden technique and applied it in their respective classes. The knowledge and understanding of the participants increased by 64%.
