Physiological behavior of arabic coffee seedlings (Cv. obatá and catucaí) submitted to water deficitComportamento fisiológico de mudas de cafeeiro arábica (Cv. obatã e catucaí) submetidas à deficiência hídrica
(2019-12-16)
In this work, biometric characteristics and pigment content were assessed in Arabica cv. Obatã and Catuaí cultivated under water deficit (WD). The experiment was conducted in an agricultural greenhouse from December to ...
Leaf Spraying of Manganese with Silicon Addition Is Agronomically Viable for Corn and Sorghum Plants
(2020-09-01)
Leaf spraying of manganese (Mn) is widely used in annual crops due to its deficiency in the soil. Silicon (Si) addition in the spray solution with Mn could favor physiological and nutritional aspects and the production of ...
Foliar application of rare earth elements on soybean (Glycine max (L)): Effects on biometrics and characterization of phytotoxicity
(2020-10-01)
This study aims at investigating the effects of foliar application of aqueous solutions of La3+ and Ce3+ nitrates on soybean plants (Glycine max). First, we observe that Triton HW 1000 surfactant at 0.01 vol% reduces ...
Imidacloprid-mediated stress on non-Bt and Bt cotton, aphid and ladybug interaction: Approaches based on insect behaviour, fluorescence, dark respiration and plant electrophysiology
(2021-01-01)
Plants and insects are parts of a complex system that involves interactions among many trophic levels, and it is important to understand the nature of such interactions. In the complex of interactions involving aphids and ...
Aesthetic and sensory quality of Emerald grass (Zoysia japonica) as a function of substrate cultivation and mineral fertilization
(2020-07-01)
Ornamental lawns, such as Emerald grass (Zoysia japonica), require adequate fertilization management for their development, as well as the substrate used as a base in cultivation is of great importance to improve the ...
Nutrition and physiology of hybrid Eucalyptus urograndis in soil fertilized with sewage sludge
(2020-01-01)
Sewage sludge is a residual pollutant product from the treatment of urban effluent and must be adequately processed before final disposal in order to avoid environmental contamination. The use of sewage sludge in agricultural ...
Nutrients Uptake in Shoots and Biomass Yields and Roots and Nutritive Value of Zuri Guinea Grass Inoculated with Plant Growth-promoting Bacteria
(2019-12-16)
The objective of this study was to evaluate the effects of plant growth promoting bacteria (PGPB) inoculation in Zuri guinea grass [Megathyrsus (syn. Panicum) maximus] on shoot dry weight (SDW) and root dry weight (RDW) ...
Silicon in Pre-sprouted Sugarcane Seedlings Mitigates the Effects of Water Deficit After Transplanting
(2020-09-01)
This study is aimed at assessing whether silicon (Si) can mitigate the effects caused by water stress in pre-sprouted seedlings (PSS) in sugarcane after their transplanting in the soil and what is the best form in the ...
Enhanced Tolerance to Cold in Common Bean Treated with Biostimulant
(2021-03-01)
Plants exposed to suboptimal temperatures suffer damage to physiological processes, growth, development and yield. Acting as enhancers of physiological and metabolic performance of plants, biostimulants have been used to ...
Si fertigation attenuates water stress in forages by modifying carbon stoichiometry, favouring physiological aspects
(2021-01-01)
Climate change has aggravated the occurrence of drought periods, affecting pasturelands in different regions of the world. Silicon attenuates water deficiency in several species, but there is a lack of research to verify ...
