An evaluation of natural infestation by leaf pests on soybean (Glycine max (L.) Merrill) cultivars

Damage caused by leaf pests of soybean on five cultivars was evaluated. Afield experiment was carried out at the Piracicaba region, cultivars Davis, IAC 73-228, PI 227.687,PI 171.451, and PI 229.358 having been compared. Leaf damage was produced by natural infestation of Anticarsia gemmatalis and Plusia sp. Cultivar PI 171.451 showed lower comsumption of leaves in relation to control ('Davis') and other cultivars. Damage was more serious on IAC 73-228 than on PI 227.687 and PI 229.358.

Aproveitamento de um fosfato natural parcialmente solubilizado pelas culturas do arroz, milho e soja: I. Resultados preliminares

Em solos pouco ácidos, pobres em P disponível, dois dos quais anteriormente com vegetação de cerrado, foram conduzidos ensaios destinados a comparar a eficiência de um fosfato natural parcialmente acidulado com ácido sulfúrico (FAPS) com a do super simples (SS) e a do fosfato de Araxá original. Usaram-se as culturas de arroz de sequeiro, milho e soja. Verificou-se que: (1) o FAPS deu produções que não diferiram estatísticamente das obtidas com o SS sendo maiores que as conseguidas com o FA; (2) os resultados das análises de solos e da diagnose foliar indicam que o FAPS funcionou como fonte de P, Ca e S.
