“…Since water is the main interference factor in plant physiological processes (Gouveia Neto, 2011), and its restriction triggers plant phenological development acceleration, DM and nutrient partitioning between the different plant organs is changed. Although developing grains act as strong photoassimilate sinks in the plant (Dantas Júnior et al, 2010;Soratto et al, 2013;Santos et al, 2015), in the season cultivation, where there was greater water availability (Figure 1), DM allocation to stem and leaf growth was high, even after flowering (Figure 2e, f, g, h), confirming reports that stress affects photoassimilate partitioning in plants (Thornley, 1972;Cruz et al, 2004).…”

The aim of the present study was to evaluate dry matter partitioning and macro-and micronutrient accumulation and distribution in small-sized castor plants grown in season and off-season. The experiments were conducted during the 2005-2006 season and in the 2006 off-season in an Oxisol. A completely randomized block design was used, with eight replications. Plots consisted of plant sampling periods, which were conducted in the vegetative period (17 days after emergence -DAE), the grain fill period (between 73 and 80 DAE) and at end of the cycle (120 DAE). Castor leaves accumulated most of dry matter (DM) and macroand micronutrients in the vegetative period, regardless of the growing period. In the following cycle periods, most of biomass and nutrients were located in the reproductive structures and grains, especially in the offseason crop. It was concluded that leaves and stems are strong nutrient sinks in the castor plant in season crops, while lower water availability during off-season induces plants to use physiological mechanisms to allocate more resources (biomass and nutrients) for their reproduction.Additional keywords: dry matter; macronutrients; micronutrients; Ricinus communis; source/sink relation. ResumoObjetivou-se neste estudo avaliar a partição de matéria seca, o acúmulo e a distribuição de macro e micronutrientes em mamona de porte baixo, cultivada na safra e na safrinha. Os experimentos foram conduzidos na safra de 2005-2006 e na safrinha de 2006, em Latossolo Vermelho distroférrico. Utilizou-se do delineamento em blocos casualizados, com oito repetições. As parcelas foram constituídas pelas épocas de coleta de plantas, que foram realizadas na fase vegetativa (17 dias após a emergência -DAE), na fase de enchimento de grãos (entre 73 e 80 DAE) e no final do ciclo (120 DAE). As folhas da mamoneira, na fase vegetativa, acumularam a maior parte da matéria seca (MS) e dos macros e micronutrientes, independentemente da época de cultivo. Nas fases seguintes do ciclo, a maior proporção de biomassa e nutrientes estava presente nas estruturas reprodutivas e nos grãos, especialmente no cultivo de safrinha. Conclui-se que, no cultivo de safra, as folhas e os caules são fortes drenos de nutrientes na planta de mamona, enquanto na safrinha a menor disponibilidade hídrica faz com que as plantas utilizem mecanismos fisiológicos para alocar mais recursos (biomassa e nutrientes) para sua reprodução.Palavras-chave adicionais: macronutrientes; matéria seca; micronutrientes; relação fonte/dreno; Ricinus communis.

“…Thus, the N applied pre-sowing improved the NUE with a pronounced effect on the biomass yield (Table 4). Although the maximum uptake of this element occurs from flowering to seed filling (Hungria et al, 1985;Soratto et al, 2013b), the results showed that regardless of when the NT system was adopted, the application of N at pre-sowing increased the biomass production by 36 to 40% over management systems without pre-sowing N application (Table 4). This finding indicates the importance of fertilization with N during the initial stages of common bean crop grown in a NT system, regardless of its age.…”

In the no-till (NT) system, N availability may change depending on the number of years since NT was adopted. us, an experiment was conducted in a Typic Rhodudalf in Botucatu, São Paulo, Brazil, to evaluate the in uence of the age (timing of establishment) of the NT system and N fertilizer management on the nutrition, yield, and N-use e ciency (NUE) of common bean (Phaseolus vulgaris L.) crop. Treatments included four management systems (a newly implemented NT system, an established NT system, a newly implemented NT with an application of 60 kg ha -1 N at pre-sowing, and an established NT with an application of 60 kg ha -1 N at pre-sowing) and four N rates (0, 30, 60, and 120 kg ha -1 ) sidedressed at the V 4 stage of common bean. e age of the NT system did not a ect common bean nutrition or its response to sidedressed N application, but the established NT system, regardless of N application at pre-sowing, provided a slightly greater common bean yield. In both the newly implemented and established NT systems, N fertilization increased the aboveground biomass, seed yield, and protein concentration in seeds. Even with the application of N at pre-sowing, seed yield increased in response to sidedressed N fertilization in all the management systems. e NUE by common bean was greater in treatments receiving N at pre-sowing. A higher seed yield and NUE of common bean grown in the NT systems a er grass was achieved with the combined application of N at pre-sowing and sidedressing.

“…The amounts of macronutrients required for uptake and exportation by plants for the production of each ton of pod's fresh matter are shown in Table 4. Lower demand of P and higher demand of N, Ca, and S for the common bean than that observed for snap bean has been reported (Soratto et al, 2013;Pegoraro et al, 2014). Faquin and Andrade (2004) highlighted the vegetable crops larger requirement of K in relation to N, a fact observed by authors such as Grangeiro et al (2004) for watermelon, Silva Júnior et al (2006) for melon, Vidigal et al (2007) for pumpkin and Tetsukabuto and Fernandes et al (2011) for potato.…”

Obtaining nutrient accumulation curves is very important in knowing the plant nutritional requirement dynamics and to direct the strategies for its supply. The aim of this work was to study the uptake, compartmentalization and exportation of macronutrients of a snap bean genotype with determinate growth habit. An experiment at field conditions at Londrina State University -UEL, Londrina-PR, Br azil, was performed in a randomized block design with five replications, using UEL-1 genotype. It was observed that dry matter production, as nutrients accumulation, were slow until 20 days after emergence (DAE), V4 stage, and became more pronounced after that period. The macronutrients were more accumulated in the pods, except for Ca, which had the leaves as preferred organ. The maximum amounts of N, P, K, Ca, Mg and S uptaken were 91.0; 35.2; 131.1; 35.2; 9.1 and 4.7 kg ha -1 , respectively, while exportation to produce each ton of pod's fresh matter were 7.01 kg of N; 3.30 kg of P; 7.91 kg of K; 0.6 kg of Ca; 0.48 kg of Mg and 0.31 kg of S. One must pay attention to the proper management of quantity and epoch of N and K supply, because of the high demand and exportation of these nutrients.
