| Summary: | Rice becomes the most widely cultivated food crop by households and becomes the
main source of carbohydrates and source of calories. Increasing production to meet
food needs for the population that continues to increase always get the top priority
in agricultural development in Indonesia with its main strategy in the form of
intensification of farming. Tobacco plants (Nicotiana tabacum L.) which have been
known as one of the biopesticide ingredients are thought to have alelochemical
content that can increase rice production. This research is aimed at knowing the
effect and optimal treatment of concentration and interval combination of tobacco
(Nicotiana tabacum) extract application on yields that include dry biomass harvest,
number of puppies, weight of 1000 GKG grains, percentage of grain, yield per crop
and estimated productivity of rice plant (Oryza sativa) Inpari 32 varieties. The study
consisted of 10 treatments consisting of 9 treatments that were a combination of
concentration (1ml/l, 2ml/l, 3ml/l) with intervals (1 week, 2 weeks, 3 weeks) of
tobacco extract solution and 1 control (without the application of tobacco extract),
with 3 repetitions per treatment. The results showed that the concentration and
interval of tobacco extract application had a significant effect on the percentage of
paddy grains and the weight of 1000 GKG grains in rice plant (Oryza sativa) Inpari
32 varieties. The combination treatment of concentration 2 ml /l with a 1-week
application gave the best effect on the yield of rice (Oryza sativa) Inpari 32 varieties. |
