The aim of this study was to develop mathematical models estimate the leaf area common bean (Phaseolus vulgaris) in irrigated and non-irrigated water regimes from linear dimensions. An experiment carried out a completely randomized design with 3×2 factorial arrangement (three cultivars: Triunfo, Garapiá FC 104; two regimes: non-irrigated) 25 replicates each. A total 523 trifoliates were collected throughout crop cycle. length (L, cm) width (W, central leaflet trifoliate measured their...
Abstract The objective of this work was to evaluate the yield, leaf area, stomatal conductance, photosynthesis, transpiration, and critical fraction transpirable soil water (FTSWc) hybrid landrace corn (Zea mays) genotypes, as affected by deficit characterized FTSW. Two experiments were carried out in 2015/2016 2016/2017 crop years: one field other a greenhouse. following genotypes evaluated irrigated nonirrigated systems: Cinquentinha Bico de Ouro landraces AS 1573PRO improved cultivar....
Rice (Oryza sativa L.) is the main staple food of more than 50% world’s population. However, global production may need to increase by 70% before 2050 meet requirements despite increasing challenges due environmental degradation, a changing climate, and extreme weather events. in Ecuador, mainly concentrated lowland tropical plains, declined recent years. In this paper, we aim calibrate validate Kobayashi’s ‘Very Simple Model’ (VSM) and, using downscaled corrected climate data, quantify...
Os substratos são utilizados na maioria dos cultivos em plantas ornamentais. Entre suas características essenciais, destaca-se o valor do potencial hidrogeniônico (pH), que pode influenciar a disponibilidade de nutrientes às plantas, podendo favorecer sua absorção, dificultar e ainda causar fitotoxidez. Apesar da importância, as informações auxiliem manutenção para adequar necessidades das escassas. Desse modo, presente trabalho foi conduzido com objetivo avaliar neutralização acidez...
Fruit flies of the Tephritidae family are among most important invasive crop pests that have wide repercussions since their latent phase, with economic losses and rigorous quarantine limitations imposed by many countries to avoid entry. The biological control fruit using parasitoids order Hymenoptera has received great attention is considered a promising method in integrated management tephritid pests. Diets for feeding importance can vary from simple sugar solution nutritionally complete...
As variações na temperatura do ar ocasionam consequências diretas produção agrícola Brasil, cuja economia é baseada neste setor em vários estados. O estudo pode auxiliar no planejamento a fim de aperfeiçoar este processo. objetivo deste trabalho foi caracterizar para região Cachoeira Sul Rio Grande (RS). Utilizaram-se dados 2007 2016 Instituto Nacional Meteorologia (INMET) da estação meteorológica A813 (Vaisala, MAWS 301; lat: -29º52’; long: -52º23’; alt: 107m). Calculou-se média, mínima e...
Abstract The objective of this work was to evaluate the tolerance soybean (Glycine max) cultivars flooding stress at different growth stages. experiment arranged in a 2x2x5 factorial arrangement, with two sowing dates (October and November), (TECIRGA 6070RR NA 5909 RG), five stages (SE-EM, EM-VC, VC-V2, V2-V4, V6-V8) 2018/2019 2019/2020 crop years. experimental design completely randomized four replicates. For both evaluated cultivars, stage most sensitive soil SE-EM. After seedling...
The objective of this study was to characterize the development chia plants sown at different dates, and determine relation between duration cycle final number leaves leaf appearance rate on main stem. A field experiment conducted in agricultural year 2016/2017 five sowing dates (09/22/16, 10/28/16, 01/03/17, 02/08/17 03/24/17) edaphoclimatic conditions central region RS, Brazil. randomized block design with four replicates used. For each date, vegetative reproductive phases days °C day (Tb...
Abstract Several authors report that potassium (K) is the nutrient absorbed in greater amounts by gerbera plants. Thus, objective of determining concentration Kin solution substrates for growing potted gerbera, quantified Cardy Horiba C-131 and an atomic absorption spectrophotometer, correlating them with each other plant leaf content. The experiment was carried out a greenhouse. experimental design randomized complete blocks using 5×2 factorial scheme (5 substrates/2 cultivars) four...
The influence of water deficit on plant physiological and biochemical responses as measured by the fraction transpirable soil (FTSW) has not been investigated in cultivars developed world's largest soybean producer. This information can help obtain plants with improved tolerance to abiotic stress that most affects production Brazil, enabling adaptation edaphoclimatic conditions enhance crop's yield potential. We aim determine FTSW threshold for transpiration evaluate changes growth,...
O feijoeiro comum, Phaseolus vulgaris, é sensível à deficiência hídrica, e o silício pode promover maior tolerância a esse estresse abiótico. Para testar essa hipótese, objetivou-se avaliar doses de foliar na ao déficit hídrico em feijão. experimento foi conduzido casa vegetação, com delineamento experimental blocos inteiramente casualizados esquema fatorial 6 x 2 quatro repetições. Utilizou-se seis (0; 0,5; 1,0; 1,5; 2,0; 2,5 kg Si ha-1) sem hídrica floração. Os vasos capacidade L foram...
Bean’s productivity is below its productive potential, and among the related factors sensitivity to water deficiency. Silicate fertilization may aid better tolerate this abiotic stress. Therefore, work aims evaluate effects of foliar silicon (Si) doses in development tolerance deficiency for bean’s cultivation. The experiment was conducted a greenhouse, with completely randomized block design 6x2 factorial scheme four repetitions. Six (0; 0.5; 1.0; 1.5; 2.0; 2.5 kg Si ha-1) without flowering...
Entre as importâncias da caracterização climática para diferentes setores economia, podemos destacar a agricultura, uma vez que estas informações podem subsidiar diversas tomadas de decisões. A precipitação pluvial apresenta grande variabilidade espaço-temporal e constitui das principais fontes perdas na produtividade agrícola. Desta forma, este trabalho teve por objetivo caracterizar (PP) Cachoeira do Sul. Utilizou-se dados dos anos 2007 2016 Instituto Nacional Meteorologia (INMET) estação...
The increase of the world population associated to concentration this in urbanized environments has caused growth production residues organic solids, that most times are discarded inadequate places can pollute environment. Another factor is also related demand for more food, mainly agricultural products, which need different inputs, such as fertilizers productivity. Given context, it essential use technologies allow recycling nutrients from waste, have potential condition soils and fertilize...
The soybean is an alternative of diversification and financial return to the rice farmer. However, it presents difficulties cultivation low yield due physical characteristics soil. In this scenario, objective work was verify influence soil scarification, genetic material used sowing date. Three cultivars, with potential classified as “medium”, “high” “very high”, were sown in a scarified non-scarified area, dates november 7th december 10th, year 2018. scarification opperation occurred on...
Abstract The objective of this work was to evaluate the response Garapiá, Triunfo, and BRS-FC104 bean (Phaseolus vulgaris) cultivars water deficit represented by fraction transpirable soil (FTSW). experimental design completely randomized in a 3×2 bifactorial arrangement (cultivars × irrigation no irrigation). Transpiration, growth, yield were evaluated crop season off-season. In season, with low atmospheric air demand (below 15 hPa 55% days), 'Garapiá' presented early stomatal closure...
O uso de métodos estatísticos para avaliar o crescimento e produção das plantas é crucial avanço tecnológico do feijoeiro.
