Análise do desenvolvimento de Beta vulgaris 1. Em canteiros com diferentes doses de cinza vegetal proveniente de eucalipto em solo argiloso.

Abstract

The ash is from vegetable biomass, burned in factories boilers, the ones that are transformed into energy. Considering that the ash is a by-product from this biomass burning, the disposal, most of times, occurs in a wrong way ending in contaminating the environment, salinizing the soil and consequently affecting lives in the ecosystem. So, the present paper aims at studying a viability of using ash from eucalyptus in beetroot growing. The experiment was conducted in Itambe city, Parana state, and the experimental design was completely randomized with a total of 3 repetitions per treatment. The ash from eucalyptus was obtained in the property itself, and the treatments which were employed consist of: T1 = 0, T2 = 10, T3 = 20, T4 = 30, T5 = 40 ash tons per hectare. The biometrical and morphological parameters were evaluated and the results were submitted to an Test F through software Sisvar And later it was done the test of regression to 5% of probability. The ideal dose for beetroot growing was around 20 tons per hectare, and as it was provided more ash, the development of the plant has reduced. It was possible to conclude from this work that ash is a viable alternative as source of nutrients for the growing of beetroot. However, it is crucial that when applying the ash over the plantation, the nutrients levels present in the ash are taken into consideration, otherwise phytotoxicity may occur.
