ABSORÇÃO DE NUTRIENTES POR MUDAS DE PIMENTÃO MICORRIZADO CULTIVADO EM SUBSTRATO COM PÓ DE COCO

Abstract

This work had for objective to test the coconut dust as one of the components of the substratum recommended in the production of seedlings of green pepper (Capsicum annuum L.) and that the inoculation with arbuscular mychorrizal fungi (AMF) it turns the most efficient plant in the absorption of nutrients, especially the phosphorus. A Yellow Red Argissolo was used, the substrata dust dry coconut and dust green coconut. The plants had been inoculated by AMF (Glomus clarum, Glomus intraradices and margarita Gigaspora). The experiment was lead per 45 days, the plants had been supplied weekly with exempt nutritional solution of P and to the end collected and submitted to the analyses of: dry mass of the aerial part, leaf number, height of the plant, diameter of caule, contend of macronutrient and micronutrient of the aerial part of plant. The delineation was of blocks casualizados with eighteen treatments and four repetitions. The results had demonstrated that10% dust dry coconut the seedlings of green pepper presented better results in mass dries of the aerial part, height, number of leves and diameter of caule
