RESUMOA berinjela tem grande importância nutricional e socioeconômica, sendo cultivada comercializada em vários países, principalmente ambiente protegido; sua produção, assim como a de inúmeros cultivos agrícolas, é dependente fatores água, nutrientes luz; propôs-se, assim, com este trabalho, avaliar as trocas gasosas, fluorescência da clorofila temperatura foliar protegido diferentes lâminas irrigação. O estudo foi realizado casa vegetação utilizando-se delineamento inteiramente...
Extreme weather events, such as severe droughts, pose a threat to the sustainability of beef cattle by limiting growth and development forage plants reducing available pasture for animals. Thus, search species that are more tolerant adapted soil water deficit conditions is an important strategy improve food supply. In this study, we propose utilizing mathematical concept Manhattan distance assess variations in morphological variables tropical grasses under water-limited conditions. This...
Silicon (Si) fertilization is widely recognized to improve the development of crops, especially in tropical soils and cultivation under dryland management. Herein, our working hypothesis was that Si stoichiometry favors efficient use carbon (C), nitrogen (N), phosphorus (P) sugarcane plants. Therefore, a field experiment carried out using 3 × factorial scheme consisting three cultivars (RB92579, RB021754 RB036066) forms application (control without Si; sodium silicate spray at 40 mmol L-1...
Core Ideas Performance of salicylic acid to reduce the effects water deficit in cowpea seedlings. Oxidative protection seedlings under deficit. Salicylic improve biochemical metabolism The cultivar BRS Itaim is suitable for semiarid regions by its tolerance Drought stress one greatest problems facing agriculture and a critical factor affecting success or failure agricultural activity. Application an elicitor substance plants, such as (SA), might be strategy induce acting especially on...
Abstract BACKGROUND:The presente paper aims to compute climatological zones apt for the cultivation of pitaya based on trends in occurrence climate change events from IPCC Brazil. We used temperature and precipitation data 4,942 cities collected NASA / POWER platform 1990 2020 elaborate current scenario. The scenarios were obtained using CHELSA (Climatologies at high resolution earth's land surface areas) corresponded periods 2041-2060 2061-2080 associated with four scenarios. spatialization...
O tomateiro é exigente em água, porém este um recurso limitado na região semiárida necessitando de manejo que resulte maior produção e melhor aproveitamento dos recursos hídricos. Objetivou-se então, com esta pesquisa, avaliar o efeito taxas reposição da evapotranspiração cultura sobre a do 'Caline IPA 6' ambiente protegido. experimento foi conduzido casa vegetação pertencente à Universidade Estadual Paraíba cinco (33, 66, 100, 133 166%) foram estudadas delineamento inteiramente casualizado,...
The objective of this study was to evaluate gas exchange and yield components cowpea cultivars under different levels water stress in the semiarid Paraiba. experimental design randomized blocks factorial 3 x 4, with three replications. In factor A allocated varieties BRS Guariba, BR17 Gurguéia Marataoã B four irrigation established terms fractions reference evapotranspiration (40, 60, 80 100% ETo) replicates. Gas exchanges were determined from measurements internal CO2 concentration,...
Abstract Water deficits have been considered the most restrictive environmental constraint on agricultural production worldwide. The current study aimed to investigate role of silicon nutrition (Si) in activating defence mechanisms against drought damage cowpea cultivars. experiments were carried out a randomized block design 2 × 4 factorial scheme, corresponding two cultivars (BRS Novaera and BRS Tumucumaque), water regimes (control well‐irrigated deficit) four Si levels (0, 1.0, 2.0 4.0...
Genotype × environment (G×E) interaction is an important source of variation in soybean yield, which can significantly influence selection breeding programs. This study aimed to select superior genotypes for performance and yield stability, from data multi-environment trials (METs), through GGE biplot analysis that combines the main effects genotype (G) plus genotype-by-environment interaction. As well as, path analysis, determine direct indirect influences components on grain as a strategy....
Cowpea is a crop with great economic, social and food importance in semi-arid regions, but its production drastically reduced by the water deficit these requiring better management strategies that allow crop’s production. This study therefore aimed to evaluate photosynthetic efficiency of cowpea cultivars under irrigation replacement levels. The experiment tested three genotypes (G1 = ‘BRS Aracé’, G2 ‘BR 17 Gurguéia’ G3 Marataoã’) four depths (40, 60, 80 100% ETc), resulting 3 x 4 factorial...
Abstract Salicylic acid (SA) has been considered to attenuate the effects of abiotic stresses on plants, including water deficit that intensely affects growth and production plants. The goal this work was evaluate role SA in alleviation stress watermelon seedlings a morphophysiological biochemical level. experiment consisted application at concentrations 0, 0.25, 0.50, 0.75 1.0 μmol L −1 leaves grown three levels retention (100%, 75% 50% WRL). To effect aspects, plant height, leaf area,...
ABSTRACT The intensive cultivation of vegetables with frequent chemical fertilization may cause accumulation nutrients in the soil. This, turn, reduce crop yields and damage environment due to contamination ground water rivers. Thus, increase effects P (0, 100, 200, 300 400 kg ha -1 P2O5) K 60, 120, 180 240 ha-1 K2O) doses on growth productivity radish cultivars (Sakata 19 Sakata 25) a soil high levels these nutrients, two experiments were conducted randomized blocks factors arranged 2 x 5...
Our working hypothesis was that magnesium (Mg) supplementation modulates plant performance under low water availability and improves drought tolerance in soybean genotypes. Plants of Bônus 8579, M8808 TMG1180 genotypes were grown field conditions subjected to three stress treatments (control, moderate severe stress) Mg levels [0.9 (low), 1.3 (adequate) 1.7 cmolc dm - ³ (supplementation)]. After 28 days imposition, the growth parameters, osmotic potential, relative content, leaf succulence,...
Lettuce and cucumber are two important vegetables cultivated in greenhouses. Intercropping can increase the yield without increasing demands for inputs. A more efficient use of resources production systems reduce costs environmental impacts. We evaluated land equivalent ratio (LER) intercropping lettuce as a function population. An experiment was conducted greenhouse to evaluate population density (100, 85, 70, 55% 2.35 plants m−2) cultivars, ‘Lucy Brown’ ‘Vanda’. The affected amount...
O cultivo protegido de melão vem alcançando posição destaque no Brasil, permitindo obter colheitas durante o ano todo, maior controle patógenos e doenças, redução da perda nutrientes por lixiviação, diminuição estresse fisiológico das plantas favorecer melhoria na qualidade produção. Objetivou-se avaliar com este trabalho, aspectos morfofisiológicos, rendimento, frutos eficiência do uso água pelo meloeiro "Gália" cultivado em ambiente sob diferentes lâminas irrigação. experimento foi...
ABSTRACT To evaluate the photosynthetic efficiency, gas exchange and yield of castor bean intercropped with peanut under Brazilian semiarid conditions, a field experiment was set up six treatments four replicates arranged in randomized block design.
