American Journal of Plant Sciences (AJPS) , 2017, DOI: 10.4236/ajps.2017.812202
Abstract: The objective of the present study was to characterize the duration of the phenological stages, the agronomic characteristics and grain yield in soybean cultivars with contrasting cycles and indeterminate growth type, submitted to different fertilization investment environments under no-tillage system in the central region of Minas Gerais. The work was conducted under field conditions, in an experimental area of Embrapa Maize and Sorghum, in Sete Lagoas, MG, in the harvest of 2015/2016. Ten soybean cultivars with different relative maturity groups (RMG) were studied, representing almost all RMG materials currently sown in Minas Gerais, in two environments with different levels of fertilizer investment. The variables were submitted to analysis of joint variance, in order to verify the existence of interaction between cultivars and investment in fertilization environments. Fertilizer investment levels influence grain yield of soybean cultivars of contrasting cycles. The higher height of the soybean plants implies higher lodging and lower grain yield. This situation is aggravated by the greater investment in fertilization. The difference between the cycles of the cultivars is in the duration of the vegetative stages, being greater in the later cultivars.

Abstract: behavior analysts have some difficulties in communicating their knowledge to other scientific communities, mainly to those that could apply it, like teachers, parents, nurses, engineers and so on. this essay presents some reflections, as well as promotes discussions, on the reasons why those difficulties occur, and points out ways to overcome them. the adequate communication between behavior analysts and non-analysts is important on account of the social return it conveys.

American Journal of Plant Sciences (AJPS) , 2017, DOI: 10.4236/ajps.2017.810163
Abstract: The use of organic waste in agriculture has been used aiming at greater productivity, decrease in the cost of production and sustainable use of resources. The present study aimed at evaluating the effect of phosphate fertilization with the maintenance of organomineral fertilizers, combining poultry manure and soluble or reactive phosphate, in the production of grains in corn culture and the residual effect for subsequent crops of beans and soybeans. The experiment was conducted in Sete Lagoas, MG, in 2015, using three fertilizers with sources of different phosphorus sources (triple super phosphate—STP, organomineral with STP and organomineral with Bayovar phosphate) applied at the doses of 65, 130, 195 and 260 kg·ha¯1 of P2O5 total, and compared to the control without phosphate fertilization. We evaluated the contents of foliar P, P accumulation in the grains, yields of corn grains, beans and soy, accumulated productivity and export of accumulated P of the three cultures. The three cultures assessed presented higher productivity when compared to the average of the factorial treatments that received phosphate fertilization relative to the control. Organomineral fertilizers increased grain production, obtaining average productivity equal to or greater than those obtained with the exclusive use of STP.

Abstract: Este trabalho foi conduzido em Coimbra, MG, no ano agrícola 1996/97 e objetivou avaliar a ocorrência de insetos fitófagos e de predadores no milho e no feijoeiro cultivados em sistema exclusivo e em policultivo. Foi realizado um cultivo de milho (25/10/1996 a 24/03/1997) e dois cultivos de feij o[o primeiro de 25/10/1996 a 20/01/1997 (cultivo "das águas") e o segundo de 25/03/1997 a 21/07/1997 (cultivo "da seca")]. Realizaram-se contagens diretas das popula es de insetos fitófagos e de predadores nas culturas. Menores densidades populacionais de herbívoros considerados preferenciais da cultura do milho [Dalbulus maidis (Delong & Wolcott) (Homoptera: Cicadellidae) e Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae)] e do feijoeiro [Diabrotica speciosa (Germ.), Cerotoma arcuata (Oliv.) (Coleoptera: Chrysomelidae) e Empoasca kraemeri (Ross & Moore) (Homoptera: Cicadellidae)] estiveram associadas ao cultivo consorciado. As densidades de herbívoros generalistas como Thrips tabaci Lind. (Thysanoptera: Thripidae) e Pseudoplusia includens (Walk.) (Lepidoptera: Noctuidae) foram maiores no feijoeiro consorciado com o milho. No cultivo "das águas", o total de insetos fitófagos foi maior no feijoeiro consorciado com o milho do que no feijoeiro cultivado exclusivamente, sendo que o inverso ocorreu no cultivo "da seca". Os predadores Anthicus sp. (Coleoptera: Anthicidae) e Hymenoptera: Formicidae foram mais abundantes no milho e no feijoeiro cultivados exclusivamente do que as culturas foram consorciadas.
