Plants, in general, require composition, concentration, and volume of nutrient solutions which different depends on the type and phase of plant growth. Leaf vegetable crops such as lettuce (Lactuca sativa L.) require higher Nitrogen (N) nutrients than other vegetable crops, but the problem we faced at the moment is the hydroponic nutrients that are traded only in the general form of nutrient, therefore the addition of N nutrients in the form of calcium nitrate (Ca(NO3)2) needs to be done to meet the needs of lettuce plants. This study was aimed to determine the effect of the addition of Ca(NO3)2 and to find the optimum dosage of the addition of Ca(NO3)2 to the general hydroponic nutrition of vegetables on lettuce use DFT hydroponic system. The treatments consisted of five levels which are nutrition AB Mix general vegetable as a control, and nutrition AB Mix with the addition of 30 g, 60 g, 90 g, and 120 g Ca(NO3)2. The results of the observation showed that the treatment of the addition of Ca(NO3)2 fertilizer had a very significant effect on all observed variables, except for the diameter of the lettuce plant. The optimum addition of Ca(NO3)2 for lettuce was found at 90.04 g with a maximum yield of 207.92 g.","PeriodicalId":56241,"journal":{"name":"Agrotrop Journal on Agriculture Science","volume":"10 1","pages":"190"},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43438493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Robusta coffee plants (Coffea canephora P.) in general can be reproduced generatively by seeds, while the vegetative method can be done by grafting, cuttings, and tissue culture. Breeding of robusta coffee by generative method was often unsatisfactory, therefore the propagation of Robusta coffee is recommended using vegetative methods, namely cuttings. This study aims to determine the effect of leaf area cutting and the concentration of shallot extract and its interaction on the growth of Robusta coffee cuttings. This study used 2 factors in factorial design, namely: percentage of leaf cutting and the concentration of shallot extract. Variables observed were shoots growth time, shoots length, shoots diameter, number of leaves of seedling, leaf area of ??seedling, number of primary roots, length of primary root, oven dry weight of the root, oven dry weight of shoots, leaf oven weight, photosynthetic partition coefficient and total dry weight of plants.The results of this study showed that the best growth of Robusta coffee cuttings was shown in the 0% leaf cutting treatment with the heaviest total dry weight of the seedlings, which was 4.35 g and experienced an increase of 131.38% compared with 75% leaf cutting.
