Abstract
The inadequate treatment of fish waste and other organic materials has had a negative impact on the environment; this serves as a pest host because they are vectors of diseases that affect health. This is the reason that led to investigate the subject and thus evaluate the response in beet cultivation in Supe Pueblo. The objective was to determine what dose of organic fertilization with compost based on fish waste will give a higher yield. From the applied methodology, experimental approach; the Completely Randomized Block Design was used which consists of blocks (3) and treatments (5). The doses corresponded to T (1) with 0, T (2) with 640, T (3) with 770, T (4) with 900 and T (5) with 1030 kg / ha of compost (Bio – Acopez) and was applied 14 days after transplant. The data regarding physical characteristics that were obtained were processed by variance analysis and Duncan. Also, the nutrients concentrated in leaves, stomatal density and profitability were analyzed. Determining the result at a T (5) standing out for stem length being 43.85 cm., plant with weight of 301.416 g., commercial yield with 40.12 t / ha., total stem length with 55.25 cm., bulb diameter with 7.80 cm. In total nitrogen consumption T (5) with 275.32 kg / ha.; stomatal density in leaves T (5) with 827 stomata / mm2 and profitability with 254.3 %. It concludes that a higher dose of compost T (5) with 40.12 t / ha. of beet is different to 30.58% with respect to the control. Thus, this dose added nutrients to the soil, which meant that there was greater availability for plant absorption, thus influencing strengthening and therefore greater yield. It also obtained profitability more than double the investment and contamination was minimized at an environmental level.
