Concerns with water crisis involve all sectors of society and irrigated agriculture remains the main consumer. This study evaluated an agricultural production system for lettuce cultivation in greenhouse, "organic potponics", to economize manure use, using a Simplified Irrigation Controller (SIC), based on soil matric potential monitoring. Five irrigation volumes were pots 4.8 L, fertilized 200 g vermicompost. One was controlled SIC. The other represented 130, 80, 60 33 % that by SIC...
The increased demand for fish, combined with the ecological difficulties caused by overfishing, has produced a favorable environment expansion of aquaculture in recent decades. This increase also leveraged irregular release wastewater that contributes to eutrophication water bodies. study assessed cultivation basil (Ocimum basilicum L.) irrigated fish different substrate types. experimental design was 2x2 factorial design, two growth environments (organic and washed sand) irrigation sources...
Two experiments were performed to evaluate the effect of ash (40, 80, and 120 g per plant), castor cake (140 280 plant) water depth (135, 165, 191, 213 mm) on growth production organic tomato cultivated in pots a greenhouse. The experimental design was randomized blocks, irrigation managed using an automatic device. following variables evaluated: plant heights, numbers leaves, bunches, flowers fruits, total mass marketable fruits with blossom-end rot, diameter fruits. Most showed gains...
Clomazone and saflufenacil are herbicides extensively used worldwide to weed control. We studied the effects of these two on morphoanatomical parameters Setaria viridis. Plants were sprayed with four concentrations each herbicide (clomazone: 500, 1000, 1500 2000 g active ingredient (ai) ha−1 saflufenacil: 49, 98, 147 196 ai ha−1) besides control (without spraying) 20 days after transplantation. The experimental design was completely randomized five replicates per treatment. Pigment content,...
Cotton is the most important crop for fiber production worldwide. However, cotton boll weevil (CBW) an insect pest that causes significant economic losses in infested areas. Current control methods are costly, inefficient, and environmentally hazardous. Herein, we generated transgenic lines expressing double-stranded RNA (dsRNA) molecules to trigger interference-mediated gene silencing CBW. Thus, targeted three essential genes coding chitin synthase 2, vitellogenin, ecdysis-triggering...
Seedling production is an important step in the lettuce system. However, there a tendency to apply excessive irrigation at this stage. The aim of study was test use Simplified Irrigation Controller (SIC) under two conditions: first, with sensor installed substrate (measuring soil water tension) and second, atmosphere ("atmospheric" - responding vapor demand atmosphere) control seedlings. performance SIC evaluated by monitoring plant traits. seeds Regina cultivar were sown styrofoam trays...
Black pepper is widely produced in Brazil, though there are few studies related to its water requirements and the effects of deficit (WD) applied under tropical conditions. The growth, sensitivity WD, first-year productivity irrigated plants from Bragantina cultivar were evaluated, employing an irrigation system with automatic management. cultivated plastic pots installed field for 391 days using emitters different flow rates (2.2 [T1], 3.3 [T2], 4.3 [T3], 5.3 L h–1 [T4 – control]). Fresh...
The center of origin and domestication Piper nigrum L. are in high rainfall regions. But when grown regions with irregular or insufficient rainfall, irrigation becomes essential. This study evaluated the impact levels on physiological growth characteristics black pepper plants, cv. Bragantina. It was carried out from April 2019 to May 2020, using automatic activation irrigation. We used emitters different flow rates apply water depths corresponding 100, 81, 62, 42% crop requirement....
Trinta e seis híbridos de milho provenientes do programa melhoramento da EMBRAPA Milho Sorgo foram avaliados em condições contrastantes adubação NPK delineamento látice quadrado 6 x 6, com duas repetições, no município Ivaiporã-PR, na safra 2023/2024, visando identificar eficientes responsivos ao uso NPK. As características avaliadas florescimento masculino (FLOR), estande final plantas (EST), altura (ALT), inserção primeira espiga (AE), diâmetro espigas (DIAM), número (NE) produtividade...
O sorgo sacarino [Sorghum bicolor (L.) Moench] vem ganhando espaço e se consolidando em áreas de cultivo todo o mundo, sendo uma cultura complementar a cana-de-açúcar (Saccharum spp.) na produção etanol, pois possui caules suculentos rico açúcares fermentáveis. Este trabalho teve como objetivo determinar curvas maturação genótipos provenientes do programa melhoramento da EMBRAPA Milho sorgo, através avaliação perfil acúmulo açúcar no colmo ao longo tempo, com foco estabelecer período...
O Brasil é o maior produtor e exportador de Soja no mundo. Na última safra 2022/2023 país alcançou recorde produção com 150,36 milhões toneladas do grão, sendo Estado Paraná responsável por 22,37 toneladas. Diante disso, para que a produtividade seja sempre pós-safra, necessário utilização tecnologias irão evitar possíveis perdas. A convivência da cultura soja as plantas daninhas reduz produção. Atualmente, competição um desafio os sojicultores. Herbicidas pré-emergentes são fundamentais...
O Brasil está entre os maiores produtores de soja (Glycine max L.) do mundo, tendo a cultura relevância econômica significativa no país. uso da mecanização agrícola exerce um papel fundamental para aumentar sua produtividade. Dentre todas as atividades agrícolas relacionadas ao cultivo soja, colheita mecanizada se destaca como processo fundamental, necessitando conhecimento técnico apropriado. estudo teve propósito analisar perdas grãos durante na região centro norte Paraná utilizando duas...
