Field production of Kale (Brassica oleracea var. Acephala) with different nutrition sources kale production

Abstract

Objective: Quantify  development and production of kale in the field with organic and mineral fertilization. Design / methodology: Brassica oleracea var. Okay auct. cultivar “dwarf blue curled” was installed in the field under a DCA with five treatments and five repetitions each one (mineral fertilization to the soil, organic fertilization to the soil, mineral to the soil and foliar, organic to the soil and foliar and a control). After transplanting every 15 days in situ, the number of leaves was quantified and the phenological stages of the crop were identified. At 116 dat with destructive sampling, were quantified, the number, length, fresh weight, resistance to penetration and ascorbic acid content in kale leaves. Results: The growth kinetics  with organic soil and foliar fertilization excelled from the other treatments. In the cut, 1.5 to 3 bunches per plant is obtained, the resistance increased in leaves with organic products. Ascorbic acid increased leaf with anyone  fertilization. Limitations implications: Little knowledge in crop management. Conclusions: Kale is a crop that responds to different sources of fertilization.  Organic soil and foliar fertilization is an alternative for the agroecological production of kale, It´s  little-grown  vegetable in Mexico. The crop can be produced in the Texcoco area.

Key words: Kale, organic fertilization, mineral fertilization, ascorbic acid.
