Respon Pertumbuhan Dan Hasil Bawang Merah (Allium Ascalonicum L.) Terhadap Pemberian Volume Air Dan Pupuk Kandang Sapi
ABSTRACT
Red onion productivity in Indonesia, especially in Riau province, is still low, mainly due to environmental factors. One of the factors that determine red onion plant production is water availability. Water availability for shallot growth can be increased through the application of organic materials, one of which is cow manure. This study aims to determine the response of the interaction of the amount of water and cow manure on the growth and yield of shallots and to determine the best treatment combination. The research was conducted in the gauze house of the experimental garden of the Faculty of Agriculture, Riau University. This research was conducted using a divided plot design with 2 treatment factors and 3 replications. The main factor was the amount of water for watering with 3 treatment levels, namely: A1 = 100% of the needs/plant/day, A2 = 75% of the needs/plant/day, A3 = 50% of the needs/plant/day and the subplot factor is the dose of cow manure with 4 levels, namely: P1 = 15 ton.ha-1 equivalent to 37.5 g/polybag, P2 = 30 ton.ha-1 equivalent to 75 g/polybag, P3 = 45 ton.ha-1 equivalent to 112.5 g/polybag, P3 = 60 ton.ha-1 equivalent to 150 g/polybag. This study contained 10 parameters, namely soil moisture content, C-Organic, plant height, number of leaves, number of tubers per clump, tuber diameter, fresh tuber weight, shelf-worthy tuber weight, harvest age and tuber weight shrinkage. Data obtained from this research were statistically analysed by analysis of variance using SAS application. The results showed that the application of cow manure at a dose of 45 tonnes ha-1 increased the growth and production of shallots. The combination of watering 75% of plant needs per day with 45 tonnes ha-1 of cow manure significantly increased plant height, number of leaves, fresh tuber weight, storable tuber weight and harvest age of shallot plants. Application of 45 tonnes.ha-1 of cow manure showed the best growth and production at each water application dose.
