Los sistemas de producción de forrajes se pueden mejorar con la incorporación de especies alternativas con altos atributos nutricionales. El objetivo del estudio fue evaluar el potencial forrajero y productividad del agua (PA) en patrones de cultivos forrajeros que incluyeron canola (Brassica napus L.), chícharo (Pisum sativum L.) y soya (Glycine max L.) como cultivos alternativos. Se compararon los patrones alternativos maíz-maíz-canola, sorgo-sorgo-canola, maíz-maíz-chícharo y soya-maíz-avena con los patrones convencionales, alfalfa, maíz-avena y maíz-maíz-avena. El estudio se realizó de abril de 2009 a abril de 2011 en Matamoros, Coahuila, México. Se determinó la composición química del forraje, los rendimientos de materia seca (MS), nutrientes y PA en la producción de MS, proteína cruda (PC) y energía neta para lactancia (ENL). La incorporación de canola en los patrones con maíz o sorgo en primavera y verano incrementó el rendimiento de PC (34.4 %) y la PA (33.3 %), sin disminuir los rendimientos de MS y ENL, al compararse con el patrón convencional maíz-maíz-avena. Los patrones que incluyeron canola  registraron mayores rendimientos de MS y ENL, utilizando el 83 % del volumen de agua requerido por alfalfa, pero con menor rendimiento de PC (19 a 25 %). La PA y el rendimiento de PC se incrementaron en el patrón soya-maíz-avena, pero con menores rendimientos de MS y ENL. En los patrones maíz-maíz-chícharo y maíz-maíz-avena los rendimientos de MS y nutrientes y PA fueron similares. Los resultados indican que la incorporación de canola y soya en los sistemas de producción de forrajes incrementa la productividad del agua.

Êste trabalho, que reune resultados de ensaios de secagem efetuados em Campinas pelo processo de ar quente, em um secador em forma de túnel yertical, semi-industrial e especialmente construido para êsse fim, representa uma contribuição para o estudo da desidratação de diversos dos nossos alimentos. Observou-se que os produtos amiláceos, tais como batatinha (Solanum tuberosum L.), cenoura (Daucus carota L. var. sativa D.C.), ervilhas (Pisum sativum L.), mandioca (Manikot utilissima Pohl) e mandioquinha (Arracacia xanthorrhiza Bancr.) podem ser sêcos entre 40 e 55°C de temperatura, em tempo variável de 5-10 horas, conforme a densidade de distribuição do material nas bandejas do secador. O feijão guandu (Cajanus cajan L. Millsp.) bem como a batata doce (Ipomoea batatas Lam.) constituíram exceção ao tempo de secagem, levando 15 horas para secar.

Two O2 ramping techniques (linear versus exponential) were used to investigate the response of H2 evolution from intact nodules of soybean (Glycine max (L.) Merr. 'Maple Arrow'), stem-girdled soybean, pea (Pisum sativum L. 'Juneau'), and common bean (Phaseolus vulgaris L. 'Ex Rico 23') to increasing O2 concentrations from 20 to 100% over a 30-min period. The data indicate symbiosis-specific responses to the two ramps, and possible implications for determination of O2 limitation of N2 fixation. Key words: Hydrogen evolution, legume, nitrogen fixation

Newfoundland livestock farmers import all feed grain legumes. Our objective was to compare field pea (Pisum sativum L.) and soybean [Glycine max (L.) Merr.] nodule formation, plant growth, grain and protein yield potential in Newfoundland. Two-year experimental mean pea yield was high (≈0.3 t grain ha–1), although lodging was severe. Vision soybean yielded around 400 kg grain protein ha–1 when seeds were inoculated, even with soil temperatures below 20°C. Despite reasonable yield potentials, agronomic adaptation problems mitigate against the local production of all common feed grain legumes in the near future.

AbstractFeeding stem–leaf–pod explants with d-chiro-inositol and d-pinitol was used as a method to modify α-d-galactosides in developing pea (Pisum sativum) seeds. Four genotypes differing in the composition of raffinose, stachyose and verbascose (raffinose family oligosaccharides or RFOs) in seeds – high RFOs (cv. Tiny), low RFOs (SZD175) and low verbascose (cv. Hubal and cv. Wt 506) – were studied. Although seeds of all examined pea lines were able to take up both d-chiro-inositol and d-pinitol, only d-chiro-inositol was effectively converted into its galactosides: mainly fagopyritol B1 (O-α-d-galactopyranosyl-(1 → 2)-d-chiro-inositol) and fagopyritol B2 (O-α-d-galactopyranosyl-(1 → 6)-O-α-d-galactopyranosyl-(1 → 2)-d-chiro-inositol). In seeds of pea lines naturally containing low levels of verbascose (cv. Hubal) and low RFOs (SZD175), the enhanced accumulation of fagopyritols depressed the RFO level by c. 64 and 20%, respectively. Moreover, in both genotypes, about 25 and 30% of total galactose bound in α-d-galactosides occurred in fagopyritols. d-Pinitol present in the pea seeds was converted into monogalactosides, but their accumulation was several-fold lower than that of fagopyritols and did not significantly influence the accumulation of RFOs. Pea seeds with the composition of soluble carbohydrates modified by feeding with either of the cyclitols were able to complete germination.
