Comportamiento agronómico del cultivo de Jamaica (Hibiscus sabdarifa) sometidos a diferentes distanciamientos de siembra y dosis de fertilización edáfica en Alfredo Baquerizo Moreno

The present experimental work will be carried out in the lands of the farm “COMARGARA S.A” property of Mr. Marco Pineda, in the canton Alfredo Baquerizo Moreno “Jujan” –Guayas. The UTM coordinates are 656666.814 E and 9783501.198 N, with a height of 7 msmn. The area has a tropical climate, with an average annual temperature of 24.2 ° C, annual rainfall 1 879 mm, relative humidity 82%.The soil is deep with a clay texture, drainage and regular fertility. The variety called Víctor was used, from the El Inca Sector, Pichincha province. Nine treatments were studied, with different planting distances such as: (1 m between plants and 0.80 m between rows; 1 m between plants and 1.10 m between rows, and 1 m between plants and 1.5 m between rows), and edaphic fertilization doses based on the following levels (219 kg / ha N, 60 kg / ha P, 105 kg / ha K; 146 kg / ha N, 40 kg / ha P, 70 kg / ha K; 73 kg / ha N, 20 kg / ha P, 35 kg / ha K). For this purpose, the application was carried out at 30, 60 and 90 days after sowing. The data evaluated were the following: Percentage of emergence, Plant seizure, Plant height, Stem diameter, Days to flowering, Days to Physiological Maturation, Number of Flowers, Flower Diameter, Flower Weight, Flower Yield and economic analysis. The yield variable determined that treatment 1, in the interaction of fertilization levels and sowing density (219 kg/ha N, 60 kg/ha P, 105 kg/ha K; 1,00 m x 0,80 m) the highest production was 466.20 kg / ha. Followed by treatment 2, with (146 kg / ha N, 40 kg / ha P, 70 kg / ha K and spacing of 1.00 x 0.80 m) with 461.58 kg / ha. And that treatment 3 (73 kg / ha N, 20 kg / ha P, 35 kg / ha K and with a distance of 1 m between plants and 0.80 m between rows) has the highest net benefit / cost ratio of 2.14. It has a production cost (1659.63 dollars / ha).
