1. A aplicação exógena foliar de ácido abscísico desencadeia mecanismos de tolerância à deficiência hídrica em seringueira
Resumo O ácido abscísico (ABA) é conhecido como o hormônio mais influente em desencadear mecanismos de tolerância a estresse em plantas, inclusive à deficiência hídrica. No entanto, o efeito da aplicação exógena como indutora de tolerância pré-estresse é pouco estudado em plantas de interesse agronômico. O objetivo deste trabalho foi avaliar o

2. PERCOLATE QUALITY IN SOIL CULTIVATED WITH APPLICATION OF WASTEWATER FROM SWINE SLAUGHTERHOUSE AND DAIRY PRODUCTS
ABSTRACT The objective of this study was to evaluate the quality of the percolate in soil columns cultivated with Tiffon-grass 85 under different wastewater rates from swine slaughterhouse and dairy. The experiment was conducted at the Department of Engineering at the Federal University of Lavras, in PVC columns with 0.30 m of diameter and 1.2 m deep, filled

3. CHEMICAL PROPERTIES OF SOIL FERTIRRIGATED WITH DAIRY AND SLAUGHTERHOUSE WASTEWATER
ABSTRACT The aim of this study was to evaluate the soil chemical properties submitted to fertigation with slaughterhouse (SW) and dairies (DW) wastewater. The experiment was conducted in the Environmental Engineering Center and Sanitary of UFLA/MG in PVC columns filled with Dark Red Latosol (Oxisol) and randomly distributed. The treatments applied with nitro

6. Soil nitrate level variation under intensive nitrogen fertilized coastcross pasture.
Nitrate levels in soil profile after the first N application on coastcross pasture, grown on a dark red latosol (Hapludox), in Sao Carlos, SP, Brazil, under tropical altitude climate, were measured at 7-day intervals, to monitor possible losse in depth. Soil nitrate rates varied with high rates of N-ammonium nitrate (200kg ha per cutting) in surface layers.

7. Ammonia losses by volatilization from coastcross pasture fertilized with two nitrogen sources.
Ammonia losses by volatilization from five rates of urea or ammonium nitrate surfacce-applied coastcross pasture, grown on a dark red latosol (Hapludox) in Sao Carlos, SP, Brazil, under tropical altitude climate, werw measured. Volatilized ammonia was absorbes in traps placed on soil surface. The mean losses from urea applied after five sucessive cuttings of

8. Dry matter production response of coastcross (cynodon dactylon) (L.) pears) to sources and rates of nitrogen.
Dry matter production of a coastcross pasture grown on a dark red latosol (hapludox), in Sao Carlos. Sao Paulo State, Brazil, under tropical altitude climate, was evaluated. The goal was to verify the efficientcy of N rates as urea and ammonium nitrate: 0,25,50,100 and 200kg ha per cutting, in five periods. Both sources were equally efficient. The mean N rat

9. Quinoa (Chenopodium quinoa) reaction to herbicide residue in a Brazilian Savannah soil.
The quinoa (Chenopodium quinoa Willd.) cultivation, one of the most promising in double cropping with soybeans or maize, depends on weed control. The objective of this work was to evaluate quinoa reaction to herbicide residue in a savannah soil. Six herbicide treatments, trifluralin, pendimethalin, clomazone, imazaquin, trifluralin + imazaquin and control, w

10. Influence of micronutrients on dry matter yield and interaction with other nutrients in annual crops.
The objective of this work was to determine the influence of Zn, Mn and Cu on shoot dry matter yield and uptake of macro and micronutrients in upland rice, common bean and corn. Six greenhouse experiments were conducted using a Dark Red Latosol (Typic Haplusthox). Treatments consisted of application of Zn at 0, 5, 10, 20, 40, 80 and 120 mg kg-1, of Mn at 0,

11. Potassium supply to cotton roots as affected by potassium fertilization and liming.
Cotton (Gossypium hirsutum) is known to have a high requirement for K and to be very sensitive to low soil pH. Most of K reaches plant roots by diffusion in the soil. As K interacts with Ca and Mg, liming can interfere in K movement in the soil, affecting eventually the plant nutrition. The objective of this work was to study the effect of dolomitic lime and

12. Influencia da relacao calcio:magnesio do corretivo na nodulacao, producao e composicao mineral da alfafa.
O objetivo deste trabalho foi avaliar o efeito da relacao Ca:Mg do corretivo da acidez do solo na producao de materia seca, composicao mineral da alfafa, e nodulacao. O solo utilizado foi um Latossolo Vermelho-Escuro distrofico. Utilizou-se o delineamento inteiramente casualizado em esquema fatorial com seis relacoes de Ca:Mg (1:0; 1:1; 2:1; 3:1; 4:1, na dos
