In the Indonesian economy, the oil palm commodity plays a pretty bright role because it serves as a source of foreign exchange. The need to develop technology in producing superior seeds. In this study discuss about the Influence of Giving Fertilizer and Mikoriza Against the Growth of Palm Oil Plants (Elaeis guineensis jacq.) In Pre-Nursery Nursery. This study aims to determine the effect of manure and mycorrhizal fertilization as well as its interaction on the growth of coconut plants in pre-nursery nurseries. The study was designed by Factorial Randomized Block Design consisting of 2 treatment factors. The first factor of treatment of manure (K) consisting of 4 levels, namely: K0 = 0 kg / polybag, K1 = 0.15 kg / polybag, K2 = 0.30 kg / polybag, and K3 = 0.45 kg/polybag. The second factor of mycorrhizal treatment (M) consisting of 4 levels, namely: M1 = 12.5 g/polybag, M2 = 25.0 g/polybag, M3 = 37.5 g / polybag. The results showed that the treatment of cow manure up to 0.45 kg/polybag can increase the height of seedlings, stem diameter, total leaf area, wet weight of seedlings and dry weight of seedlings, but did not affect the number of oil palm seedlings.Mikoriza treatment up to 37, 5 g / polybags can increase seed height, stem diameter, total leaf area, wet weight of seedlings and dry weight of seedlings, but have no significant effect on the number of oil palm seedlings. The interaction between cow manure and mycorrhiza had no effect on all parameters observed.

Research to explain the characteristics of organic vegetable consumers, analyze the decision-making process for purchasing organic vegetables, analyze consumer behavior towards organic vegetables and analyze the relationship between consumer characteristics and consumer behavior towards organic vegetables in July-December 2018. The research area was determined by purposive sampling, namely in the Market Modern Lotte Mart, Transmart Care Shop and Forward Together Pulo Brayan. The number of samples taken is 90 samples. The method of collecting data in this study is primary and secondary. Data analysis used descriptive analysis, Fishbein multi-attribute and Spearman Rank correlation. The attributes studied include; price, taste, nutrient content, color, aroma, freshness, packaging, neatness, durability, shape and size, brand, product quality, and expired information. The results of the study showed that the majority of organic consumers of women aged 31-40 years, work as private employees who have an income level of Rp. 2,000,000-Rp. 3,000,000 per month and have two family members covered. The decision making process for purchasing organic vegetables, consumers have a safe motivation for health by consuming organic vegetables and the realization of a healthy lifestyle into the expected benefits. Organic vegetables have the advantage of freshness attributes, nutrient content, and expired information from other attributes after consuming them. Consumer characteristics do not have a real relationship with consumer behavior towards organic vegetables.

This study was aimed to obtain the method in the study of callus induction of in vitro. The research activities were carried out at Laboratory of Biotechnology, Faculty of Agrotechnology, Andalas University. This research used decriptive and experimental methods. One-way ANOVA analysis followed by Duncan’s test was used to determine significant differences (P ≤ 0.05). All statistical analysis were performed using the SPSS Ver. 23 statistical software package. The results showed that medium of callus induction is 4,0 mg/L BAP + 0,5 mg/L IAA with formation of callus (days), and average of callus formed, namely 4,33 days, and 9,67 callus.

Two different methods for determining irrigation water requirement for corn, is KP-01 and Thornthwaite-Mather method. Two Methods have different parameter such as reference crop evapotranspiration (ETo) and effective rainfall. The average ETo value using Penman-Monteith for Thornthwaite-Mather was lower (82,5%) than using Penman Modification method (KP-01) . The ratio of effective rainfall between KP-01 and Thornthwaite-Mather was 33,02%. Corn water irrigation requirement for a pattern planting based on KP-01 is 806,96 mm, while corn water irrigation requirement based on Thornthwaite-Mather method is 254,4125 mm. Corn water irrigation requirement using KP-01 is higher than Thornthwaite-Mather because effective rainfall method for KP-01 (using USDA Soil Conservation Service) is lower than rainfall effective for Thornthwaite-Mather.

The water resource problems in dry season at Jatinangor dry land are the imbalance between water needs and water availability. Technology that can help the farmers in dry season is by using a runoff water harvesting system for irrigation use. Irrigation interval is applied so that water use is more efficient. The purposes of this study are to calculate crop water requirement of sweet corn (Zea mays L. Saccharata Sturt) by using Cropwat 8.0 Software and to find out the use of runoff water harvesting systems on one day interval irrigation in the dry season. This research use descriptive analysis method. The results showed that based on Cropwat 8.0, the crop water requirement of sweet corn is 300,6 mm/periode and the runoff water harvesting pond can fulfill the irrigation water needs of sweet corn in the dry season with actual irrigation water requirement of 55,6 m3 on 221 m2 width of area. The productivity yield of sweet corn is 13,25 tons /ha.
