Existem muitas informações sobre o potencial matricial de água no solo adequado para o reinício de rega em sistema de plantio convencional, mas há poucas informações sobre qual o melhor potencial da água do solo para o controle da irrigação em sistema de plantio direto (SPD). Dessa forma, objetivou-se estudar o efeito de cinco de níveis de irrigação sobre a produtividade, o teor de sólidos solúveis e a acidez em frutos do tomateiro para processamento, cultivar Hypeel, cultivado no SPD em Latossolo Amarelo. O experimento foi conduzido sob delineamento experimental em blocos casualizados, com cinco tratamentos e quatro repetições. Os tratamentos consistiram de cinco valores de potencial matricial de água no solo para reinício da irrigação (m a 13 cm de profundidade medido por tensiômetros): -15 kPa, -30 kPa, -45 kPa, -60 kPa e -75 kPa. A produtividade máxima foi obtida quando o valor de tensão da água do solo esteve em -28,5 kPa. O teor máximo de sólidos solúveis foi obtido quando o valor de tensão da água do solo alcançou valores em torno de -50,8 kPa.

Coleus blumei Benth (Lamiaceae), popularly known in Brazil as heart-hurt or coleus-of-Java is an ornamental plant widely used due to the color of its leaves. Several species of the genus Coleus present compounds with antioxidant, antimicrobial and allopathic activities due to the presence of chemicals such coleonol, forskolin and rosmarinic acid. Therefore, this study aimed to carry out phytochemical study and biological tests to evaluate the antibacterial, antioxidant and allopathic activities of the 70% ethanol extract and its fractions ethyl acetate, dichloromethane and end aqueous fraction leaf of Coleus blumei Benth. The plant extract was prepared by turbolisis from the powder of dried leaves, as a solvent for extraction using 70% ethanol. The ethanol extract was fractionated with solvents dichloromethane and ethyl acetate. The phytochemical study identified the presence of saponins, free anthraquinones, flavonoids and anthocyanidins. In evaluating the antibacterial dichloromethane fraction showed activity against all microorganisms tested both in agar diffusion test and microdilution test. The 70% ethanol extract showed activity against the micro-organisms S. aureus and S. epidermidis in agar diffusion test and against all microorganisms tested in microdilution test. The ethyl acetate fraction showed activity against the micro-organism S. aureus in the agar diffusion test and against all microorganisms tested in microdilution test. The end aqueous fraction showed no activity against any micro-organism tested. In the test of evaluation activity allopathic dichloromethane fraction showed greater inhibition of seed germination and growth of tomato (Lycopersicon esculentum Mill), followed by 70% ethanolic extract, the ethyl acetate fraction and the end aqueous fraction. In testing the antioxidant activity with DPPH ethyl acetate fraction showed higher antioxidant activity followed... (Complete abstract click electronic access below)

In this work evaluated the content of vitamin C and total carotenoid in tomatoes fresh and dehydrated for conserve, with posterior immersion in sauce, verifying its sensorial acceptability. Dehydration was performed in dryer with airflow at 70 °C to obtain a product with final moisture of 45%. Determinations were carried out ascorbic acid, soluble solids, acidity, sugars and carotenoid before and after the dehydration process. The dehydrated tomatoes had been immersed in three types of sauces (pepper sauce, oregano with parrot leaves sauce and garlic sauce) per 25 days. After this period, the dry tomatoes in conserve had been submitted to the sensorial analysis in the pate form, applying themselves preference test. The results had been showed that retention of vitamin C and total carotenoid in the dehydrated product showed retention of 14.0% and 44.3%, respectively, in tomatoes after the dehydration process. Among the formulation of canned t
