Sixteen weekly staggered planting of two wheat varieties, trigo 1 and Trigo 2 were planted from October, 1982 to January, 1983 to determine the climatic influence from planting to maturity and identify the suitable planting dates and its effect on wheat phenilogy. Results showed that highest yields were obtained when wheat was planted in the month of December. The number of filled florets and 1000-seed weight were highly and positively correlated with yield of both varieties while lenght of ripening period and total growth duration were negatively correlated with yield. Longer vegetative periods were found to be highly correlated with high relative humidity and short air temperature range during the period. Longer reproductive periods were attributed to high solar radiation, low wind velocity, low maximum air temperature and low mean air temperature during that stage. Longer ripening period was found to be highly correlated with high relative humidity, low mean and maximum air temperature and low wind velocity during the crop was positively correlated with relative humidity but negatively correlated to maximum air temperature, air temperature range and wind velocity. Low maximum and mean air temperature coupled with low wind velocity during the vegetative stage tend to favor higher yields. Longer sunshine duration, high solar radiation, low mean air temperature and low relative humidity during the reproductive stage also tend to increase yield. At the ripening stage, high maximum air temperature, long air .........

Concernente à trajetória evolutiva histórica da pedologia na região Nordeste do Brasil, objetivo central deste estudo, pode-se dizer que ela está estreitamente ligada à história da Unidade de Execução de Pesquisa e Desenvolvimento da Embrapa Solos, situada em Recife, PE. Por isso, essas duas visões serão tratadas de forma inter-relacionadas ao longo deste capítulo. |
