“…Chen et al (2014aChen et al ( , 2014b reported that inoculation with endophytic bacterium Sphingomonas SaMR12 significantly improved the root length, root surface area, and average number of root tips in Sedum alfredii plant, as compared to uninoculated treatment. Batista et al (2016) suggested that root morphological parameters, such as total root length and root surface area, play an important role in nutrient uptake, particularly under micronutrient-limiting conditions.…”

Micronutrients are essential factors for human health and integral for plant growth and development. Among the micronutrients, zinc (Zn) and iron (Fe) deficiency in dietary food are associated with malnutrition symptoms (hidden hunger), which can be overcome through biofortification. Different strategies, such as traditional and molecular plant breeding or application of chemical supplements along with fertilizers, have been employed to develop biofortified crop varieties with enhanced bioavailability of micronutrients. The use of microorganisms to help the crop plant in more efficient and effective uptake and translocation of Zn and Fe is a promising option that needs to be effectively integrated into agronomic or breeding approaches. However, this is less documented and forms the subject of our review. The major findings related to the mobilization of micronutrients by microorganisms highlighted the significance of (1) acidification of rhizospheric soil and (2) stimulation of secretion of phenolics. Plantmicrobe interaction studies illustrated novel inferences related to the (3) modifications in the root morphology and architecture, (4) reduction of phytic acid in food grains, and (5) upregulation of Zn/Fe transporters. For the biofortification of Zn and Fe, formulation(s) of such microbes (bacteria or fungi) can be explored as seed priming or soil dressing options. Using the modern tools of transcriptomics, metaproteomics, and genomics, the genes/proteins involved in their translocation within the plants of major crops can be identified and engineered for improving the efficacy of plant-microbe interactions. With micronutrient nutrition being of global concern, it is imperative that the synergies of scientists, policy makers, and educationists focus toward developing multipronged approaches that are environmentally sustainable, and integrating such microbial options into the mainframe of integrated farming practices in agriculture. This can lead to better quality and yields of produce, and innovative approaches in food processing can deliver cost-effective nutritious food for the undernourished populations.

“…Relationship between the values of available phosphorus in soil (mg kg -1 ) and P content in leaves (g kg -1 ) in crop season 2014/15 in Chardonnay (a) and Pinot Noir (b) subjected to application of increasing doses of P. * = significant at 5% probability. takes place primarily via diffusion to the roots (Dissanayaka et al, 2015, Batista et al, 2016. Thus we expect that a smaller amount of P is absorbed by grapevines, reducing photosynthesis, carbohydrate production, protein synthesis, and transfer and accumulation of energy, which are P-dependent functions in the plant (Brunetto et al, 2015).…”

Sandy soils of the Campanha Gaúcha region have naturally low levels of available phosphorus (P), which is why special attention to pre-planting fertilization is important. However, there are no studies that enable a proper calibration method to determine P content available in soil for young grapevines. The study aimed to evaluate phosphorus fertilization for young grapevines of Chardonnay and Pinot Noir in order to provide support for the recommendation of P in sandy soils. In October, 2011 we applied six doses of P (0, 10, 20, 40, 60 and 100 kg P 2 O 5 ha-1 yr-1) in soil and transplanted cultivars of Chardonnay (experiment 1) and Pinot Noir (experiment 2). The design of each experiment was randomized blocks with ten plants and three replications. We evaluated P content in the soil and leaves. We determined plant height, stem diameter and dry matter of the pruned material from crop seasons 2011/12 to 2014/15. The addition of increasing P doses elevated P content available in soil three years after implementing the experiments, but exclusively in doses above 40 and 60 kg P 2 O 5 ha-1 in Pinot Noir and Chardonnay, respectively. However, P content in soil for every applied P dose remained below sufficiency level, and therefore growth parameters and leaf P content were virtually unaffected.

“…A higher number of leaves promote an increase in photosynthesis rate, entailing a bigger concentration of dry mass in aerial part (Table 1) (Figure 3), that way, a positive correlation between the parameters, as Table 4 shows. The growth of aerial part, occurred due to the higher concentrations of organic compounds in substrate, may influenced the development of roots (Figure 4), since the higher amount of light, proved by the correlation between the dry mass parameters (Table 4), allowed the seedling exploring the substrate in which were inserted, guarantying a greater assimilation of nutrients (MONTEIRO NETO et al, 2016;BATISTA et al, 2016).…”

One of the main responsible attributes for the good quality of seedlings is its cultivation in substrates with a good drainage and nutrients availability. This work aimed to study the production of pepper seedlings with different doses of organic compounds in substrate. The experiment was carried out in August, 2018, at Educational Foundation of Andradina, in Andradina, São Paulo State, Brazil. The experimental design was completely randomized, in a 2x5 factorial scheme, with two organic substrates: peaty exhausted compound (EC) and coconut fiber compound (CC), in five different concentrations: null %; 25%; 50%; 75% and 100%, with five repetitions, in total of fifty plots. The increase in the concentration of organic compounds in production of pepper seedlings promoted a greater development. It is recommended using 70% of peaty exhausted in the composition of substrate to the production of pepper seedlings and using 100% of coconut fiber in the composition of the substrate to the production of pepper seedlings.
