“…Day after emergence required in high amounts (Gallo & Miyasaka 1961;Haag et al, 1967). Regardless of the treatment, it was observed that N, K and Ca were the nutrients accumulated in larger amounts in the stem, which was similar to results obtained by Gallo & Miyasaka (1961) and Cobra Netto et al (1971) in studies with common bean.…”

“…According to Brito et al (2009), the largest proportion of N absorbed by common bean (around 80 %) was derived by symbiotic fixation, and the highest rate of N symbiotic fixation occurred at the pre-flowering stage. Haag et al (1967) found that Mg was absorbed up to 70 DAE, i.e., a similar period as observed in this study (Figure 6d). The amount of Ca accumulated in the shoot increased up to 70 DAE, different from results obtained by Haag et al (1967) andCobra Netto et al (1971), who observed Ca absorption by common bean up to 50 and 55 DAE, respectively.…”

The amounts of P, K, and S accumulated in the shoot increased up to 80 DAE (Figures 3d, 4d, and 7d), i.e., P absorption did not increase until the end of the cycle, as observed by other authors (Gallo & Miyasaka, 1961;Haag et al 1967;Cobra Netto et al, 1971).…”

“…Nevertheless, literature information on nutrient absorption by this crop is old, i.e., it was obtained in the 1960's and 1970's in situations where grain yield was lower than 1,000 kg ha -1 (Gallo & Miyasaka, 1961;Haag et al, 1967;Cobra Netto et al, 1971). …”

“…It is therefore possible that the nutritional requirements of the current common bean cultivars are not the same as those used in the 1960's and 1970's, the period in which nutrient absorption by common bean was studied and described in the literature (Gallo & Miyasaka, 1961;Haag et al, 1967;Cobra Netto et al, 1971).…”

SUMMARYThe use of cultivars with a higher yield potential and the adoption of new technology have achieved high grain yields in common bean, which probably changed the demand for nutrients in this crop. However, there is almost no information about the periods of the cycle in which nutrients are most demanded at which quantities by the main cultivars. The objective of this study was to evaluate the macronutrient extraction and exportation by the common bean cultivars Pérola and IAC Alvorada, under different levels of NPK fertilization, on a dystroferric Red Nitosol, in Botucatu, São Paulo State, Brazil. The experiment was arranged in a randomized complete block (split plot) design with four replications. The plots consisted of six treatments based on a 2 x 3 factorial model, represented by two cultivars and three NPK levels (PD0 -'Pérola' without fertilization, PD1 -'Pérola' with 50 % of recommended fertilization, PD2 -'Pérola' with 100 % of recommended fertilization, AD0 -'IAC Alvorada' without fertilization, AD1 -'IAC Alvorada' with 50 % of recommended fertilization, and AD2 -'IAC Alvorada' with 100 % of recommended fertilization) and subplots sampled seven times during the cycle. At higher levels of NPK fertilization, the grain yield and macronutrient extraction and exportation of both cultivars were higher, but without statistical differences. Macronutrient absorption was higher in the treatments with 100 % of recommended NPK fertilization (average amounts per hectare: 140 kg N, 16.5 kg P, 120 kg K, 69 kg Ca, 17.9 kg Mg, and 16.3 kg S). Regardless of the treatment, the demand for N, P, K, Ca, and Mg was highest from 45 to 55 days after emergence (DAE), i.e., in the R 7 stage (pod formation), while the highest S absorption rates were concentrated between 55 and 65 DAE. More than 70 % of P, between 58 and 69 % of N, 40 and 52 %

Biomass and nutrient accumulation and partitioning of fall‐winter safflower in a double‐cropping system of southeastern Brazil

et al. 2020

The quantification of nutrient uptake and partitioning during crop cultivation, as well as nutrients removed at harvest, are essential information to optimize nutrient management. A 2‐yr field experiment was conducted in Botucatu, São Paulo State, southeastern Brazil, to examine the biomass accumulation and nutritional requirements and removal of two safflower (Carthamus tinctorius L.) genotypes cultivated in the fall‐winter season of a double‐cropping system. Seven plant samplings were performed during the growing season, and the material was divided into stems, leaves, and reproductive structures. Seed yield and nutrient removal were determined at harvest. Safflower genotypes had similar 2‐yr average biomass accumulations and seed yields. There were greater plant growth and nutrient uptake from stem elongation to seed filling, compared to the other growth stages. The maximum rates of nutrient uptake were observed near the flowering stage. On average, a maximum uptake of 169 kg N, 16 kg P, 178 kg K, 121 kg Ca, 16 kg Mg, 15 kg S, 130 g Cu, 3298 g Fe, 420 g Mn, and 351 g Zn per hectare were required to produce about 10,500 and 1,400 kg ha−1 of aboveground biomass and seeds, respectively. Relative to the maximum aboveground nutrient accumulation, seeds contained 28% of P, 24% of N, 22% of Zn, 16% of Cu, 11% of Mg, 10% of S, 6% of K, 5% of Mn, 4% of Ca, and 4% of Fe. These quantifications of biomass and nutrient accumulation and partitioning in each growth stage of fall‐winter safflower can be used as guidelines for fertilizer recommendations for this crop in double‐cropping systems.
