Binary logit analysis was used to identify the factors influencing adoption of Global Positioning System (GPS) guidance systems by cotton farmers in 11 Mid-south and Southeastern states. Results indicate that adoption was more likely by those who had already adopted other precision-farming practices and had used computers for farm management. In addition, younger and more affluent farmers were more likely to adopt. Farmers with larger farms and with relatively high yields were also more likely to adopt. Education was not a significant factor in a farmer’s decision to adopt GPS guidance systems. |

Doesburg, P.H. van. |
A new species, Zanchius stami Van Doesburg (Insecta, Heteroptera, Miridae, Orthotylinae) from Syria, Deir-ez-Zor, is described and illustrated. Late eggs taken from the female abdomen have a peculiar chorionic process. It was found living (predaciously?) on cotton plants. It is compared with the closely related Z. alatanus Hoberlandt, 1956. Type specimens are deposited in the Rijksmuseum van Natuurlijke Historie, Leiden, two paratypes in the Národní Muzeum, Praha. |

Plantas de cobertura (PC) são fundamentais para a produção de palhada e cobertura do solo no sistema plantio direto (SPD). Entretanto, existem poucas informações do potencial de produção de matéria seca (MS) e do acúmulo de nutrientes por PC no Cerrado brasileiro, quando cultivadas na entressafra, em sucessão à soja e antecedendo ao algodoeiro. Objetivou-se nesse estudo avaliar a produtividade de MS, o acúmulo de nutrientes por PC e seus efeitos sobre a produtividade do algodoeiro. Um experimento foi conduzido no estado de Goiás, Brasil, sendo repetido durante três anos, e constou de 7 tratamentos com PC em cultivos solteiros ou consorciados: Panicum maximum Aruana, Urochloa brizantha cv BRS Piatã, Urochloa ruziziensis, Pennisetum glaucum, Sorghum bicolor... |

Adoption of precision agriculture technology has arrived considerable attention, but abandonment has received little. This paper identified factors motivating adoption and abandonment of precision soils sampling in cotton. Younger producers who farmed more cotton area, owned more of their cropland, planted more non-cotton area, or used a computer were more likely to adopt precision soil sampling. Those with more cotton area or who owned livestock were more likely to abandon, while those who used precision soil sampling longer, or used variable-rate fertilizer application were less likely to abandon precision soil sampling. |

Probit analysis identified factors that influence the adoption of precision farming technologies by Southeastern cotton farmers. Younger, more educated farmer who operated larger farms and were optimistic about the future of precision farming were most likely to adopt site-specific information technology. The probability of adopting variable-rate input application technology was higher for younger farmers who operated larger farms, owned more of the land they farmed, were more informed about the costs and benefits of precision farming, and were optimistic about the future of precision farming. Computer use was not important, possibly because custom hiring shifts the burden of computer use to agribusiness firms. |
