Available in PDF, EPUB and Kindle. Book excerpt: Existe certo antagonismo entre o crescimento (aumento da matéria seca) e o desenvolvimento (mudança de fase fenológica) do algodoeiro (Beltrão & Azevedo, 1993). Fatores do meio que promovem excessivo crescimento vegetativo, como, por exemplo, adequada disponibilidade de nutrientes e de água e condições climáticas favoráveis, implicam em efeitos negativos sobre a produção final. Em tais condições, o uso de regulador de crescimento torna-se indispensável (Kerby, 1982; Reddy et al., 1992), pois possibilita o controle do crescimento vegetativo, através da manipulação da arquitetura das plantas, sendo, atualmente, uma importante estratégia agronômica para o incremento da produtividade de algodão (Hodges et al., 1991).

Book Synopsis Crescimento e produtividade do algodoeiro em resposta a doses de nitrogênio em cobertura e aplicação de regulador de crescimento by : G. A. Pazzetti Ordoñez
Download or read book Crescimento e produtividade do algodoeiro em resposta a doses de nitrogênio em cobertura e aplicação de regulador de crescimento written by G. A. Pazzetti Ordoñez and published by . This book was released on 2003 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instalou-se no campus da FESURV, fazenda Fontes do Saber, município de Rio Verde, GO, ensaio, utilizando delineamento experimental de blocos ao acaso com três repetições, com o objetivo de avaliar o impacto do cloreto de mepiquat sobre o crescimento e a produtividade do algodoeiro herbáceo, cultivado sob diferentes doses de nitrogênio em cobertura (0, 60, 120 e 240 kg.ha-1). Para isso, semanalmente, a partir do sétimo e até os 98 dias após a emergência das plantas, avaliou-se a altura das plantas, o número de nós no caule, e a matéria seca: do caule, dos ramos, das folhas e das estruturas reprodutivas. Na colheita final, avaliou-se: a altura, o número de nós e o comprimento dos entrenós no caule, e a produtividade de algodão em caroço. Os dados dessas variáveis foram submetidos à análise de variância e regressão; os resultados mostratam que a equação que melhor se ajustou aos dados de matéria seca em função do tempo, foi a do tipo polinomial exponencial quadrática. Foi constatado que os tratamentos alteraram significativamente a taxa de crescimento da cultura e o acúmulo de matéria seca. No momento da colheita, as plantas sob maior suprimento nitrogenado atingiram maior altura em decorrência do maior comprimento dos entrenós. Entretanto, em cada dose de nitrogênio, as plantas sob aplicação do regulador de crescimento apresentaram menor taxa de crescimento da cultura, e assim, menor altura em consequência do menor número de nós e também menor comprimento dos entrenós no caule. O menor crescimento vegetativo nas plantas expostas à aplicação do cloreto de mepiquat contrastou com maior investimento de estruturas reprodutivas registrado na época de plena frutificação. Sem aplicação de cloreto de mepiquat, a produtividade de algodão em caroço respondeu de forma significativa aos incrementos no suprimento nitrogenado de cobertura, a partir de 60 kg.ha-1; sob aplicação desse regulador a natureza da resposta produtiva aos incrementos de nitrogênio foi alterada, tornando-se significativa apenas a partir dos 120 kg.ha-1. Em comparação, as plantas não tratadas, as plantas sob aplicação de cloreto de mepiquat, apenas alcançaram superioridade produtiva, significativa, na condição de suprimento nitrogenado máximo (240 kg.ha-1), o que não se justifica nem econômica e nem ambientalmente.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to address the importance of natural enemies and functional diversity for biological control in Neotropical agroecosystems. Several aspects related to the conservation of natural enemies, such as vegetation design and climate change, are discussed in Part 1 and the bioecology of several insects groups used in biological control in Latin America is presented in Part 2. Part 3 is devoted to mass production of natural enemies while Part 4 describes how these insects have been used to control of pests in major crops, forests, pasture, weeds and plant diseases. Lastly, Part 5 reports Latin-American experiences of integration of biological in pest management programs.
Book Synopsis Biostimulants in Plant Science by : Seyed Mahyar Mirmajlessi
Download or read book Biostimulants in Plant Science written by Seyed Mahyar Mirmajlessi and published by BoD – Books on Demand. This book was released on 2020-07-08 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural-based substances, ‘plant biostimulants’, have been considered as environmentally friendly alternatives to agrichemicals. Biostimulants may comprise microbial inoculants, humic acids, fulvic acids, seaweed extracts, etc. These biostimulants have biopesticide and biostimulant utilities. Elucidations on direct or microbially mediated functions of biostimulants are presented in this book to illustrate fundamental principles and recent applications underlying this technology. This book has encompassed a cross-section of topics on different concepts to describe effective strategies by using these substances and/or beneficial microorganisms within sustainable agroecosystems. I sincerely hope that the information provided adequately reflects the objectives of this compilation. “One of the first conditions of happiness is that the link between man and nature shall not be broken.” Leo Tolstoy

Book Synopsis Plant Nematology, 3rd Edition by : Roland N. Perry
Download or read book Plant Nematology, 3rd Edition written by Roland N. Perry and published by CABI. This book was released on 2024-07-12 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.
Book Synopsis Brazil¿s Cotton Industry by : James Kiawu
Download or read book Brazil¿s Cotton Industry written by James Kiawu and published by DIANE Publishing. This book was released on 2011 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brazil is one of the world¿s leading cotton producers and an important competitor of the U.S. in Asian and European cotton markets. This situation has come about as a result of trade liberalization, structural transformation of the Brazilian economy, and the emergence of new cotton producing regions using advanced technologies and benefiting from targeted government support. Brazil¿s access to additional agricultural land and recent favorable cotton prices suggest the country¿s cotton production could rise even more than previously expected. Charts and tables. This is a print on demand edition of an important, hard-to-find report.
