In spaced crop systems, understanding the interactions between different types of vegetation in agroecosystem and solar radiation is essential for surface dynamics. This study aimed to both seasonally spatially quantify characterize components balance cultivation green dwarf coconut. The experiment was conducted Santa Izabel do Pará, Brazil, monitored following meteorological parameters: rainfall, incident global (Rg), net (Rn). Landsat 8 satellite images were obtained 2021 2023, estimates...
The present work evaluated the Aquacrop model as a tool for climate risk analysis and yield prediction of cowpea, cultivated in dystrophic yellow oxisol. was previously calibrated validated two harvests, order to simulate biomass considering four applied water blades over its reproductive period. good achieved results prove model’s efficiency this kind simulation. After validation, simulation cowpea based on meteorological data (2003 2014), soil crop management 12 harvests performed. Two...
Cowpea (Vigna unguiculata (L.) Walp.) is a leguminous species widely cultivated in northern and northeastern Brazil. In the state of Pará, this crop still has low productivity due to several factors, such as soil fertility climatic adversity, especially water deficiency. Therefore, present study aimed at evaluating physiological parameters cowpea plants under different depths. The experiment was conducted Castanhal/Pará between 2015 2016. A randomized block design applied with six...
O extrativismo de produtos florestais não madeireiros na Amazônia é uma atividade que expõe o trabalhador a riscos ambientais podem afetar sua saúde e segurança no trabalho. objetivo deste estudo foi identificar os impactos psicofisiológicos físicos da coleta do fruto açaizeiro Oriental. Estudo realizado pela aplicação questionários semiabertos entrevistas estruturadas baseadas partir protocolos software Ergolândia versão 6.0 33 coletores Ilha Combú, Belém/PA. Os identificados foram:...
The culture of açaí (Euterpe oleraceae M.), originating from floodplain areas, was planted on dry land in many properties Pará, Brazil, making necessary the use irrigation. To irrigate adequately with less waste, it is that studies aim at increasing efficiency water this sector, and one ways to do so estimate evapotranspiration (ET). objective study actual daily using Surface Energy Balance Algorithm for Land (SEBAL) eastern Amazonia. Six images Landsat 8 satellite were used, estimates SEBAL...
Water availability is a crucial factor in the final productivity of cowpea. The objective this work was to evaluate production and components cowpea under different irrigation depths Amazonian conditions. experiment carried out at School Farm Federal Rural University Amazonia, municipality Castanhal-PA, using cultivar BR3 Tracuateua, from September November 2014, 2015, 2016. experimental design conducted on six blocks four treatments, where 0, 25, 50, 100% crop evapotranspiration were...
Crotalaria incana presents alkaloids that, when ingested by ruminants, culminates in the death of animals.Given problems surrounding presence plant pasture areas, objective this research was to determine phenology and development C. plants under controlled conditions Eastern Amazon.The experimental design completely randomized with four replications eight treatments.The treatments consisted collection times, from 20 160 days after emergence.The following parameters were evaluated: number...
ABSTRACT Due to the sensitivity of cowpea water deficit during dry season in Amazonian environment, there is a need for studies related management and optimization annual yield. Thus, objective was estimate crop evapotranspiration (ETc) actual (ETr), whilst also evaluating effect different irrigation depths on yield response factor (Ky) biomass (Kss) cultivar BR3-Tracuateua under edaphoclimatic conditions Amazon region. The experiment carried out randomized blocks, with six replicates four...
A calibração de sensores com Time Domain Reflectometry (TDR) em solos amazônicos é inexistente, sendo necessária para minimizar erros na estimativa da umidade volumétrica no solo (θ) pela constante dielétrica aparente do (Ka) sistemas irrigação. Assim, objetivou-se determinar e avaliar modelos θ um Latossolo Amarelo Distrófico Castanhal (PA) TDR. Foram correlacionados ajustados valores obtidos pelo método gravimétrico função Ka θ, ambos fornecidos por 4 CS616 Campbell Scientific. Seis foram...
