Effect of concentration and interval of tobacco leaf extract application on Ciherang rice production.

Rice (Oryza sativa) is one of the staple food sources for Indonesian people. Every year demand tends to increase along with the increase in population, so research is needed to increase production. This study aims to determine the effect of concentration and interval of administration of tobacco leaf extract (tobacco filtrate) on the production of rice varieties Ciherang. The research design used a factorial completely randomized design, the first factor was the concentration of tobacco filtrate which consisted of 4 levels, namely 0 ml/l, 1 ml/l, 2 ml/l, and 3 ml/l, the second factor was the interval of administration consisting of 3 levels. i.e. every 5 days, 10 days, and 15 days. Each treatment combination was repeated three times. The yield parameters observed were the number of productive shoots, the weight of rice grain per plant, and the weight of rice grain per plot. The results showed that the weight of rice grain in the plots with B3P1 treatment was 2,378.00 g. [ABSTRACT FROM AUTHOR]
