“…For example, in very dry Mediterranean environments some studies showed that seedlings with low nutrient concentration or content performed better (Trubat et al 2008, Cortina et al 2013, whereas other studies indicated that increased tissue nutrient reserves improves seedling field performance (Luis et al 2009, Cuesta et al 2010, Villar-Salvador et al 2012, Oliet et al 2013. These contrasting results suggest that insight into nursery fertilization and field outplanting should be further tested, in particular with relation to climatic planting conditions or soil characteristics.…”

Exponential fertilization during the pre-hardening stage and fall fertilization during the hardening stage have each been used independently to nutrient load seedlings. However, nursery and field responses of seedlings to the combination of exponential fertilization and fall fertilization have received little attention. Chinese pine (Pinus tabulaeformis Car.) container seedlings were exponentially fertilized with accumulated totals of 40, 80 or 120 mg N per seedling during pre-hardening, and fall-fertilized with 0, 12, 24 or 48 mg N per seedling, and were subsequently outplanted and followed for two growing seasons. Interactions of exponential and fall fertilization had significant effects on plant N content in the nursery and first-year height after outplanting. Fall fertilization promoted additional nutrient loading during hardening for the 40-80 mg N per seedling pre-hardening regimes. The highest exponential fertilization rate enhanced N concentration in foliage and roots compared to the other two rates. Maximum diameter was observed in the lowest exponential fertilization rate at the second year after outplanting. Fall fertilization enhanced foliar N concentration. Supplemental 12 and 24 mg N per seedling during fall were more effective in increasing height increment at the second year after outplanting. Our results indicate that pre-hardening fertilization is a useful tool to nutrient load Chinese pine in the nursery and facilitate outplanting performance in the field. In combination, fall fertilization has potential to further augment this response, although further research is needed to precisely match rates of pre-hardening and fall fertilization to optimize seedling performance.

RESUMOAs dimensões do recipiente afetam tanto o custo de produção quanto a qualidade das mudas de espécies florestais, e o padrão de resposta destas é dependente da especificidade da espécie. Objetivou-se com o presente estudo avaliar o efeito do tamanho de recipientes no crescimento inicial das espécies florestais Mezilaurus itauba Taub ABSTRACTThe dimensions of the container affect both the production cost and the quality of seedlings of forest species, and the pattern of response of these depends on the specificity of the species. The objective of this study was to evaluate the effect of size of containers on the initial growth of forest species Mezilaurus itauba Taub. ex Mez and Platymiscium ulei Harms. Two experiments were conducted concomitantly in nursery conditions, using the completely randomized design with five replicates. The treatments comprised of six sizes of containers: 20 cm x 15 cm (T1), 20 cm x 20 cm (T2), 23 cm x 20 cm (T3), 25 cm x 20 cm (T4), 30 cm x 20 cm (T5) and 33 cm x 23 cm (T6). After 90 days of growth, the size of containers affects differently the quality of the seedlings of both the species. The size of container 25 x 20 cm is more appropriate for the cultivation of macacaúba species while the best response to itaúba was obtained for the container 33 x 23 cm. On the other hand, the containers 20 x 15 cm and 20 x 20 cm should not be used for any of the tested species.

“…Previous studies using CRF predominantly addressed effects on seedling morphology and mineral nutrient status in the nursery (Fan et al 2004;Oliet et al 2004;Dumorese et al 2011). Subsequent outplanting performance in the field (Haase et al 2006;Luis et al 2009;Oliet et al 2009), let alone response to a wide range of nursery CRF application rates, have not been explored fully.…”

“…Measurements of non-structural carbohydrate (NSC) levels in seedlings also appear to be useful for evaluating nursery practices (Millar and Grelet 2010;Villar-Salvador et al 2015). The lack of research using a sufficiently broad range of CRF rates to cover nutrient deficiency to toxicity (Oliet et al 2004(Oliet et al , 2009Luis et al 2009;Dumorese et al 2011), hinders seedling nutrient optimization. Thus, investigation of nursery fertilization using a range of CRF rates and assessing tree seedling dry mass, mineral nutrient status, and NSC content is warranted.…”

Highlights• We demonstrated that Chinese pine container-grown seedling nutrient status and non-structural carbohydrate content were sufficient over a wide range of fertilization rates.• Fertilization at 80 mg N seedling -1 was optimal for seedling responses in the nursery and field.• Nursery fertilization using controlled release fertilizer (CRF) with a single coating layer yielded better seedling nursery performance than CRF with multiple coatings. AbstractAlthough controlled release fertilizer (CRF) with single and multiple-layer coatings are extensively used in tree seedlings, studies that compare the impact of CRF type and application rate on seedling growth, nutrient storage, and, most importantly, outplanting performance, are lacking. In the current study, container-grown Pinus tabulaeformis Carr. (Chinese pine) seedlings were fertilized with commercial CRF with either one or multiple coating layers with equivalent formulation and longevity, at six rates ranging from 40 to 240 mg N seedling -1 . Seedlings were sampled for dry mass, non-structural carbohydrate (NSC) content, and mineral nutrient status at the end of the growing season in the nursery, and subsequently outplanted for one season. Compared to Chinese pine seedlings fertilized with single-layer CRF treatments, seedlings treated with multiple-layer CRF had higher starch concentrations but reduced dry mass and N, P, K concentrations in the nursery, and reduced diameter growth in the field. Fertilization rates of 80 and 120 mg N seedling -1 generally yielded maximal plant dry mass and mineral nutrient content. Field survival peaked at 80 mg N seedling -1 . Seedling growth, soluble sugar content, and starch concentration in the nursery and survival in the field consistently decreased at rates of 200 and 240 mg N seedling -1 . In our study, optimal nursery and field performance of P. tabulaeformis were observed using single layer CRF at 80 mg N seedling -1 (3.3 g CRF l -1 media).
