Resumo: Plant growth regulators like naphthalene acetic acid (NAA) positively affect the growth and yield of crop plants. An experiment was conducted to check the foliar application of NAA on growth and yield components of cotton variety Bt.121 under field condition at research area of agriculture farm near Cholistan Institute of Desert Studies (CIDS), The Islamia University of Bahawalpur, Pakistan. The experiment was comprised of foliar application of NAA (1%) viz. T0 (control), T1 (One spray of NAA), T2 (Two sprays of NAA), T3 (Three sprays of NAA), T4 (Four sprays of NAA). The first foliar spray was applied at 45 days after sowing (DAS) and later on it was continued with 15 days interval with skilled labour by hand pump sprayer. The experiment was laid out in randomized complete block design and each treatment was replicated three times. Data recorded on growth, chlorophyll contents, yield and yield components showed a significant increase with the application of NAA. Furthermore, earliness index, mean maturity date and production rate index were also influenced with foliar application of NAA. On the basis of growth and yield parameters it can be concluded that four spray of NAA (1%) can be applied commercially under field conditions.

Um experimento foi conduzido para verificar a aplicação foliar de NAA nos componentes de crescimento e rendimento da variedade de algodão Bt.121 sob condições de campo em área de pesquisa do Instituto Cholistan de Estudos do Deserto (CIDS), Islamia University of Bahawalpur, Paquistão. O experimento foi composto de aplicação foliar de NAA (1%) viz. T0 (controle), T1 (uma pulverização de NAA), T2 (duas pulverizações de NAA), T3 (três pulverizações de NAA), T4 (quatro pulverizações de NAA). A primeira pulverização foliar foi aplicada aos 45 dias após a semeadura (DAS) e posteriormente a cada 15 dias de intervalo com pulverizador manual. O experimento foi desenvolvido em delineamento em blocos ao acaso e com três repetições. Os dados registrados sobre o crescimento, os teores de clorofila, os rendimentos e os componentes do rendimento mostraram aumento significativo com a aplicação de NAA. Além disso, o índice de precocidade, a maturidade média e a taxa de produção também foram influenciados pela aplicação foliar de NAA. Com base nos parâmetros de crescimento e rendimento, pode-se concluir que quatro pulverizações de NAA (1%) podem ser aplicadas comercialmente em condições de campo.UEL2017-05-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplied natureapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2340910.5433/1679-0359.2017v38n2p561Semina: Ciências Agrárias; Vol. 38 No. 2 (2017); 561-570Semina: Ciências Agrárias; v. 38 n. 2 (2017); 561-5701679-03591676-546Xreponame:Semina.
