RESUMOEste trabalho foi realizado com o objetivo de analisar o manejo mais adequado para a obtenção de maior produtividade para a cultura do feijoeiro grupo carioca, cultivar pérola. O experimento foi conduzido na Área Demonstrativa e Experimental de Irrigação (ADEI) da FCAV/UNESP, Câmpus de Jaboticabal-SP. Foram definidos quatro tratamentos: T1-irrigação com base na ET 0 estimada pelo método do Tanque Classe A; T2 -irrigações baseadas em leituras de tensiômetros instalados nas profundidades de 0,20 e 0,40 m; T3 -irrigações efetuadas com base na ET 0 estimada pelo método de Penman-Monteith e T4 -testemunha. Os resultados foram submetidos à análise de variância. Para a comparação das médias, foi utilizado o teste de Tukey, a 5% de probabilidade. O tratamento T3 teve menor lâmina de água aplicada do que os tratamentos T1 e T2, e também menor produtividade. Conclui-se que os tratamentos irrigados com maior frequência apresentaram maior produção de grãos. PALAVRAS-CHAVE:Phaseolus vulgaris, eficiência do uso da água, água no solo. FARIA, M. T.

COMMON BEAN PRODUCTIVE RESPONSE BY DIFFERENT IRRIGATION MANAGEMENT 2 ABSTRACTThe objective of this work was to analyze the most appropriate management to achieve higher productivity for carioca beans (phaseolus vulgaris) and pearl cultivar. The research was developed in the Demonstrative and Experimental Area of Irrigation (ADEI) of FCAV/UNESP, Campus of Jaboticabal, SP. Four treatments were used: T1-irrigation with base in ETo estimated by the method of Class A pan ; T2-irrigations based on tensiometers installed at 0.20 m and 0.40 m of depth; T3-irrigations carried out with base in ETo estimated by the PenmanMonteith method and T4-witness. The results were submitted to variance analysis. To compare the average Turkey test was used at 5% of probability. The treatment T3 had smaller applied water depth than the treatments T1 and T2, and also smaller productivity. The conclusion is that the treatments irrigated with larger frequency showed higher production of grains.

Decontaminating leaf samples from crops sprayed with pesticides and nutrient solutions is important for foliar analysis. This study evaluated the effect of different washing methods in coffee and sorghum foliage that had been sprayed with zinc (with or without surfactant). The plants were sprayed with a 3 g L-1 zinc sulfate solution, with and without surfactant. Seven days later, leaves were collected and washed. The experiment was completely randomized in a 2 x 2 x 3 + 2 factorial, with three replications. The first factor represents foliar zinc applications with or without surfactant, the second represents the number of washes (1 or 2) and the third represents the concentration of the wash solution (detergent + hydrochloric acid) at (0 + 0 mL L-1; 1.0 + 3.5 mL L-1 and 2.0 + 7.0 mL L-1). The last one represents two additional treatments without washing (zinc sprayed with and without surfactant). Surfactant strengthens contact between zinc and foliage and enhances absorption. Washing is an indispensable pretreatment for leaf analysis and our study showed that a single wash with detergent + hydrochloric acid (1.0+ 3.5 mL L-1) was the most effective washing method for coffee and sorghum.
