Abstract

The use of grafted seedlings is a cultural practice that aims at the optimization of agricultural production, and materials of organomineral added to the substrate can help in the well development. The aim of this study was to evaluate the effect of the application of increasing doses of organic and mineral material on the development of cashew rootstocks. The test was conducted in the experimental area of the Federal University of Campina Grande (UFCG), campus Pombal-PB in the period from July to September 2017. The treatments were constituted of five increasing doses of organic matter (0, 100, 200, 300 and 400 g of bovine manure) and four levels of mineral fertilizer (0, 1, 2 and 3 g of NPK). The design was in randomized blocks, distributed in factorial 5 × 4, with 4 replications. For the planting, it was used creole seeds originary of the city of Livramento do Cariri Paraibano and substrate composed by sand texture Franco sandy. At 60 days after sowing, the following variables were analyzed: plant height (cm), leaf diameter (mm), number of leaves, leaf area (cm2), fresh and dry mass, leaf, stem, shoot (g), percentage of biomass (%) and quality index of seedlings. Based on the results obtained, it is concluded that the organic and mineral combination (1 g of NPK and 200 g of bovine manure) provided the greatest increases in vegetative growth characteristics and quality of rootstocks in the cashew tree.

Highlights

The cashew tree (Anacardium occidentale L.), is a culture that has your center of origin in the Northeast of Brazil, where is very adapted to the semi-arid conditions, and as consequence produces nutritious pseudofruits, that present great appreciation mainly in the local market (Araújo, 2013)
The fertilization was performed two days before planting, incorporated to the soil organic matter and mineral components, urea, triple superphosphate and potassium chloride, as Ximenes (1995), recommendations being the source of used organic matter the bovine manure, the analysis is in the Table 2
Cashew tree seedlings at 60 days after sowing had a significant interactive effect at 1% probability (p ≤ 0.01 and ≤ 0.05) for all variables analyzed, demonstrating that both organic and mineral fertilization interfered in the development and qualities of the seedlings, except in the stem diameter that meant only for the organic input (Table 3)

Summary

Introduction

The cashew tree (Anacardium occidentale L.), is a culture that has your center of origin in the Northeast of Brazil, where is very adapted to the semi-arid conditions, and as consequence produces nutritious pseudofruits, that present great appreciation mainly in the local market (Araújo, 2013). This cultivation represents great importance in socioeconomic terms, since in addition to the pseudofruit, since products such as the almond present in the chestnut and the liquid coming from the bark are included as raw material for industries (Ferreira et al, 2016a). The objective of this study was to evaluate the effect of the application of increasing doses of organomineral material on the development of cashew rootstocks
