Responses of Tobacco Plant (Nicotiana Tabacum L.) Payakumbuh Rudau Gadang Variety to The Application of Tomato Liquid Organic Fertilizer

The availability of nutrients in plants dramatically influences the production and quality of tobacco produced need during their growth. Therefore, excess or deficiency in nutrient availability will affect tobacco production and quality (Djajadi and Murdiyati, 2000). Many tomatoes that are too ripe and nearly rotten become waste. To overcome this organic waste so that it does not go to waste, it can be used as an ingredient to make “Pupuk Organik Cair” (liquid organic fertiliser). The research aims to obtain information on what dose level of tomato POC can increase the vegetative growth and production of Payakumbuh tobacco, as well as how it affects the vegetative growth and production of Payakumbuh tobacco of the Rudau Gadang variety. The research was carried out at the experimental garden of Politeknik Pertanian Negeri Payakumbuh, Tanjung Pati, Limapuluh Kota Regency, from March to June 2022. The experiment used a randomised block design with one treatment factor, namely the tomato POC dose consisting of 5 levels, namely: (1) D0 = No Tomato POC; (2) D1 = 10 ml Tomato POC / litre of water; (3) D2 = 20 ml Tomato POC / litre of water; (4) D3 = 30 ml Tomato POC / litre of water; (5) D4 = 40 ml POC Tomato /L water. The research was carried out with five replications. The variables observed consisted of plant height (cm), number of leaves (sheets), leaf length (cm), leaf width (cm), fresh leaf weight (grams) and dry leaf weight (grams). Production observations were carried out during harvest using a destructive method by taking three samples per experimental unit. The results of research on giving tomato POC to tobacco plants at a treatment dose of 40 ml tomato POC / litre of water was a treatment that had a very significant effect on the parameters of plant height (118.33 cm), number of leaves (27), leaf length (46.36 cm), leaf width (27.93 cm), stem diameter (27.85 mm), leaf area (893.76), wet weight (234.96 grams) and dry weight (33.10 grams). Moreover, further research is recommended to obtain optimal dosage levels for the best growth and production of tobacco plants.
