Avaliou-se nesse trabalho os efeitos de lâminas de irrigacao (60%, 80%, 100%, 120% e 140% da ETc) e da cobertura do solo com filme plastico de polietileno preto sobre a produtividade, qualidade dos frutos e eficiencia do uso da agua (EUA) na cultura do tomateiro em campo, durante o periodo chuvoso, na regiao de Piracicaba (SP). O delineamento experimental foi em parcelas subdivididas distribuidas aleatoriamente no esquema fatorial 2 x 5, com quatro repeticoes. As lâminas de irrigacao nao influenciaram a produtividade total, produtividade comercial, massa media dos frutos e numero de frutos por planta. A cobertura do solo com plastico preto aumentou a produtividade total e comercial de frutos, mas reduziu o teor de solidos soluveis. A eficiencia do uso da agua aumentou com a reducao da lâmina de irrigacao, sendo esse aumento mais pronunciado com o uso da cobertura de solo.

IMPACTS OF IRRIGATION LEVELS AND SOIL COVER ON TOMATO CROP 2 ABSTRACT Water is an asset increasingly scarce and it has also a great influence on yield and quality of tomato crop, making its management a major factor to achieve higher profitability coupled with sustainability. The study aimed at evaluating the effects of irrigation depths (60%, 80%, 100%, 120% and 140% of ETc) and black polyethylene plastic as soil covering on yield, fruit quality and water use efficiency (WUE) in field tomato crop during the rainy season in Piracicaba, SP, Brazil. The experimental design was split plots randomly distributed into 2 x 5 factorial arrangement with four replications. No influence was observed of irrigation depths on total and marketable yield, mean weight and number of fruits per plant. The use of black polyethylene plastic as soil covering increased total and marketable yield, but decreased the content of fruit soluble solids. An increase of water use efficiency was observed by reducing water levels, and it was more pronounced when soil cover had been used. Keywords: Solanum lycopersicum, water level, water deficit, blossom-end rot, mulching.read more

Factors Involved in Fruit Calcium Deficiency Disorders
TL;DR: Ca2þ deficiency disorders in fruit may not be caused by a single factor, but most likely by a combination of mechanisms that lower Ca2ý concentration at a specific tissue and cell localization, leading to Ca2 þ deficiency symptoms.
