The consumer market has a strong tendency to consume specialty coffees, making it essential understand the influence of environmental conditions, such as solar radiation and altitude, on coffee quality. This study aimed analyze physical sensory quality Arabica function different altitudes incident tree. was carried out in city Manhuaçu-MG, Brazil. Three (950, 1050 1150 m above mean sea level) two sides exposure (east face: morning sun west afternoon sun) were studied post-harvest processing...
In tomato, foliar application of calcium-based nutrient solutions is used to complement soil fertilization. However, knowledge regarding the factors that influence effectiveness fertilizer applications remains incomplete. The objective this study was evaluate efficiency fertilization with calcium for improving production and quality hydroponic Sweet Grape tomatoes. An experiment conducted in a commercial system split-plit-plot scheme, two doses: 1,5 3 mmol L-1 Ca. were sprayed on leaves at...
ABSTRACT Alternative materials can be used to reduce reliance on mining for P-based fertilizers. In this sense, the pyrolysis process of bovine bones produces “bone char”, which as a source P. This study aimed characterize bone char and conduct comparative analysis with both soluble (triple superphosphate) non-soluble (Bayóvar phosphate rock) fertilizers, specifically examining its behavior in soil uptake by plants. Bone characterization was performed X-ray diffraction (XRD), attenuated...
Coffee is one of the main agricultural commodities in world. Thus, research aimed at reducing productive risks crop has been increasingly encouraged, among which use plant hormones stands out. In addition, objective this work was to analyze effect application indole-3-acetic acid on growth, nutrition and gas exchange young Coffea arabica L plants. The experiment carried out field city Alegre, Espírito Santo, Brazil. experimental design used randomized blocks, testing five doses Arabica...
Leaf analysis is an important tool to assess the nutritional status of coffee crops and allow evaluate calibrate fertilizers recommendations. For interpretation chemical results obtained by leaf analysis, several methods can be used, stands as Sufficiency Range Integrated System Diagnosis Recommendation (DRIS). The objective this work was in production from Manhuaçu region, Minas Gerais State, Brazil. A database generated with nutrient concentrations index leaves commercial fields located...
Abstract Alternative materials can be used to reduce reliance on mining for P-based fertilizers. In this sense, the pyrolysis process of bovine bones produce a product called “bone char”, which as source P. The present work aims synthesize, characterize, and evaluate solubility fertilizers extractants using bone char, Bayóvar, triple superphosphate; ‘‘ in vitro ’’ release P; investigate availability P from consecutive cultivations maize black-oat. characterization char was performed by X-ray...
