“…RUE DM of sole wheat and soybean were in agreement with previous reports (Andrade, 1995;Sinclair and Muchow, 1999). The energetic cost of symbiotic nitrogen assimilation, the higher production value of the protein and oil-rich seed, differences in canopy architecture and the comparatively high leaf nitrogen concentration, account for the lower RUE and WUE of soybean in comparison to cereal C3 species (Squire et al, 1984;Matthews et al, 1988;Sinclair and Horie, 1989).…”

“…Essa cultura possui elevado potencial produtivo e acentuada habilidade fisiológica na conversão de carbono mineral em compostos orgânicos, os quais são translocados das folhas e de outros tecidos fotossinteticamente ativos para locais onde serão estocados ou metabolizados. Além disso, apresenta pequena plasticidade foliar, reduzida prolificidade e baixa capacidade de compensação efetiva (Andrade, 1995;Fancelli e Dourado-Neto, 1997).…”

O objetivo do trabalho foi avaliar o efeito do estresse salino induzido por diferentes potenciais osmóticos das soluções de NaCl, KCl e CaCl2, na germinação de sementes e no vigor de plântulas de milho. O trabalho foi constituído por dois experimentos realizados no Laboratório de Sementes da Universidade Federal da Grande Dourados e em casa de vegetação da Embrapa Agropecuária Oeste, Dourados-MS. O delineamento experimental utilizado foi inteiramente casualizado, em arranjo fatorial 3 x 6, com quatro repetições, sendo o primeiro fator constituído pelos sais e o segundo pelos potenciais osmóticos: 0,0; -0,2; -0,4; -0,8; -1,2 e -1,6MPa. Foram analisadas as variáveis: Experimento 1 - porcentagem de germinação, comprimento de parte aérea e comprimento da raiz primária; Experimento 2 - altura final de planta, comprimento radicular, diâmetro de colmo, área foliar, teor de clorofila e massa seca de parte aérea e de raiz. A germinação não foi afetada pelo estresse salino. A diminuição do potencial osmótico nas soluções de KCl e NaCl, causou decréscimos no comprimento de parte aérea e acréscimos no comprimento da raiz primária. A condição de estresse provocada pelos sais proporciona comportamento diferenciado no vigor de plântulas de milho. O efeito salino do NaCl é maior nas características altura de planta, comprimento radicular, área foliar e massa seca de raiz.

“…Previous studies reported that yields are strongly reduced by a delay of sowing for different crops within a certain sowing range, e.g., sunflower [26,27], soybean [28], and maize [29,30]. Goyne et al [31] found that crop growth was hastened by a delayed sowing date because the crops encountered higher temperatures during the plant growing period, thus reduce the total dry biomass at harvest.…”

Abstract:Yields of rainfed potato (Solanum tuberosum L.) in China's semiarid region are restricted by limited precipitation. Climate change could cause significant fluctuation in the rain-fed agricultural production due to the spatiotemporal changes in temperature and precipitation. As adjusting sowing dates proved to be an important management technique for improving grain yields, we examined how potato production can be improved by altering planting date in China's semiarid region, thus improving potato adaptation to climate change. Field trials with five target sowing dates (from late April to early June) were carried out in Inner Mongolia, China during four growing seasons (2010)(2011)(2012)(2013), and the effects of sowing dates on potato development, yield and water use efficiency (WUE) were estimated. Results showed that although delayed sowing shortened the duration of potato growth period, non-significant thermal time differences after flowering stage was found among the treatments. However, greater precipitation was shown in three intermediate treatments.Potato yield was significantly affected by sowing dates, and intermediate sowing dates showed greater yield compared to the earlier or later sowing dates. Delayed sowing dates significantly improved WUE in a drier year. As for a normal year, earlier sowing dates promoted WUE because of less water consumption, but these increases came at the cost of reducing yields. Under the current climate conditions in the study area, the flexible sowing time for potato was determined as from early May to early June, and optimum sowing time was between 10 May and 27 May. In conclusion, adjusting sowing date affected duration, thermal time, and precipitation over potato growth period, and the optimal sowing date exhibited higher yield by obtaining greater precipitation, which could improve potato adaption to climate change.
