“…According to recent researches, reproductive compounds of safflower genotypes are negatively affected at Oxisol bulk density mean of 1.2 Mg m -3 (Paludo et al, 2017). The safflower seeds possess high oil content (35-45%), good in quality and suitable as edible and industrial oil.…”

As intensive farm development can cause changes in soil structure, it is crucial to study cultivars that can adapt to these changes, along with the climatic conditions of the Cerrado of Mato Grosso. The objective of this study is to assess the effects of soil bulk density (weight of soil in a given volume) on the agronomic performance of the safflower genotypes (Carthamus tinctorius L.). The experiment was conducted at the Federal University of Mato Grosso in a greenhouse. A completely randomized design in factorial scheme with four replications was selected. The treatments comprised of five soil bulk density levels (1.0, 1.2, 1.4, 1.6 and 1.8 Mg m -3) and ten safflower genotypes (PI 237538, PI 248385, PI 250196, PI 301049, PI 305173, PI 305205, PI 306596, PI 306603, PI 560202 and PI 613366). The following evaluations were done after completion of the experiments: total shoot dry mass, upper ring root dry mass, intermediate and lower total root dry mass. The data were subjected to the analysis of variance and the means were categorized by the Scott-Knott test at the 5% level of probability. The genotypes and soil bulk density influenced the components in isolation ways. The shoot dry mass production was impaired from the bulk density of 1.10 Mg m -3. For the root dry mass, the limit was 1.04 Mg m -3. In general, from the soil density of 1.20 Mg m -3 the growth and development of safflower genotypes were influenced negatively. The increase in soil density reduced the total root dry mass up to 71.11%.

“…In their study on safflower genotypes of different soil bulk density levels, Paludo et al (2017) recorded that the more the number of branches, the higher the number of chapters. They could thus establish a relationship between the number of branches and production of chapters in the plant, apart from a rise in the dry matter of the aerial plant parts.…”

This study aimed at estimating the wood ash as a corrective and fertilizer in the safflower crop. This study was done with respect to the development, growth, and production of safflower in response to the wood ash doses applied to Oxisol of the Brazilian Cerrado biome. Adopting the completely randomized design and using five wood ash doses (0, 8, 16, 24, 32 g dm -3 ) and six replicates, the experiments were performed under greenhouse conditions. Each experimental unit included a 2 dm 3 pot, filled with soil that had been incubated earlier for 30 days. The variables studied included soil pH, plant height (cm), stem diameter (mm), number of leaves (plant ) and root dry mass (g pot -1 ) Analysis of variance and subsequent regression test were performed for all the data using SISVAR software, at 5% probability for both. The variables internal and external diameter of the chapters and root volume showed no significant differences. The soil pH revealed a significant effect of the wood ash application tending towards linearity, as did the other vegetative variables of plant height, stem diameter, number of leaves and SPAD index. The productive constituents exhibited improved development when the wood ash was applied to the soil in doses of around 24 g dm -3 or more.

“…Thus, compression tests were performed in the laboratory using the Proctor Test -NBR 7182 (ABNT, 1986) and moisture content tests, following the methodology of EMBRAPA (2017). These procedures resulted in a value of 16% (mass basis) as the ideal compression moisture for Latossolo Vermelho (Oxisol) (FAGUNDES; SILVA; BONFIM - SILVA, 2014;PALUDO et al, 2017;PALUDO et al, 2018).…”

The aim of this study was to evaluate the effect of inoculation with rhizobium and co -inoculation with Azospirillum brasilense on phytometric characteristics of peanut plants grown in Latossolo Vermelho (Oxisol) with and without compaction. The experiment was conducted in a greenhouse, with a randomized block design in a 5x2 factorial scheme and 4 replicates, totaling 40 experimental units. Treatments were composed by commercial inoculant for peanuts (SEMIA 6144 strain); MT 15 strain; combination of MT 15 + A. brasilense; nitrogen control and absolute control. Plant height, number of leaves, number of branches per plant, stem diameter and Falker chlorophyll index were evaluated. The data were subjected to analysis of variance and, when significant, to Tukey test at 1% probability level. For the variables plant height, number of leaves, number of branches and stem diameter, the results were similar for all treatments, except for the absolute control and number of branches at 90 days after emergence (DAE) and stem diameter at 30 and 90 DAE. For stem diameter at 30 DAE, the results were similar to those found in the treatments with co -inoculation, commercial inoculant and nitrogen fertilization. There was interaction for Falker chlorophyll index at 60 DAE, with the best result found in the MT 15 strain. Inoculation with MT15 and co-inoculation with A. brasilense promoted good performance in peanut crop in terms of phytometric characteristics in soil with and without compaction.
