Abstract: Beans (Phaseolus vulgaris) are cultivated practically all over the world and have great importance for
the population in economic and cultural aspects. Due to increasing population expansion, increased
occurrences of abiotic and biotic stresses, it is necessary to develop new production technologies.
Biofortification with Se in bean culture is a strategy that can solve problems in human nutrition. The
objective of this work was to evaluate the effect of sources and doses of selenium via the leaves in the
bean crop. The study was conducted in Campo Alegre De Goiás – GO. The experiment was set up in a
randomized block experimental design in a 2x5 factorial scheme, with four replications, totaling 48
experimental plots. The first factor refers to two sources of selenium (sodium selenate –Na2SeO4 and
sodium selenite – Na2SeO3). The second factor is selenium doses (0; 100; 200; 300; 400 and 500 g ha-1
).
Data regarding plant height, toxicity levels, productivity, sieve classification, average seed weight,
number of pods and seeds per plant, seed viability test and selenium content in the grain were
evaluated. Although the results did not present a significant difference between the treatments
regarding the number of grains per plant, number of pods and number of grains per pod. The
application of Na2SeO4 at a dose of 250 g ha-1
showed better results regarding productivity. The
application of both Na2SeO4 and Na2SeO3 provided a reduction in the height of bean plants and also
showed symptoms of phytotoxicity, being more intense in the source of Na2SeO3. The best result
regarding seed viability in the first seed count was at the dose of 330 g ha-1
. It was possible to increase
the Se content in beans using both Na2SeO4 and Na2SeO3 in foliar fertilization. Agronomic
biofortification with Se in beans is best achieved at a dose of 414 g ha-1 when using Se in the form of
Na2SeO4, however it is not the ideal dose for the recommended daily intake.

Abstract: Amaranth is an important crop for food security due to its high content of essential amino acids,
vitamins and mineral salts in leaves and seeds. Little is known about the different components of
production systems, such as sowing times and cultivars adapted to different Brazilian biomes. The
objective of this work was to identify the behavior of amaranth genotypes, in red yellow latosol in
southeastern Goiás, at the Experimental Station of the State University of GoiásUniversidade
Universitária de Ipameri, regarding the production and quality of seeds as a function of four sowing
times, three in the dry season, with irrigation, and one at the end of the rainy season, without irrigation.
Seven genotypes of Amaranthus cruentus were evaluated: Alegria, Aurelia´s Verde, Elena´s Rojo,
Golden Giant, Juana's Orange, Opopeo and UEG 01 in four sowing dates (02/24, 03/31, 05/05) of 2021
and (01/12) 2022 in a randomized block experimental design with 4 sessions. Data on plant height at
flowering and maturity, seed production per kg ha-1, seed production per plant and panicle length were
analyzed. For seed quality, the following analyzes were performed: water content, germination test,
acceleration test, germination speed index, weight of 1000 seeds, electrical conductivity and seedling
length. The average temperature influenced plant height, but did not have direct autonomy with seed
yield, the highest yields occurred with sowing on 02/24/2020, using irrigation, the most productive
cultivars were Aurelia´s Verde, BRS Alegria and Elena's Rojo. For seed quality the first, second and
fourth seasons were compiled.

Abstract: Corn is one of the most significant crops, both nationally and
internationally, being the basis of human and animal food. However, in order to achieve high
yields, or the entire genetic potential of plants, they depend on fertilization, usually with mineral
nutrients. In general, when the amount of fertilizers is increased, part of what is not absorbed,
that is, the excess, is harmful to the soil, water and reduces profitability to the producer. Fungi
of the genus Trichodema spp. have been related to the production of hormones or correlated to
growth factors, providing greater efficiency in the use of some nutrients, thus allowing greater
availability and absorption by plants. The objective of the research was to evaluate the
performance of commercial corn hybrids, with the application of Trichoderma harzianum,
under different availability of nitrogen and phosphorus. Two distinct experiments were carried
out, one for N and the other for P, both conducted at the State University of Goiás, Campus Sul,
University Unit of Ipameri-GO, during the 2022/23 harvest. The experimental design used for
both experiments were in a factorial scheme (9 x 3), in randomized blocks, with nine
commercial hybrids and three doses. For the nitrogen experiment three doses of N were used,
control (160 kg ha-1
of N), low N (80 kg ha-1
of N) and low N+
(80 kg ha-1 + Trichoderma
harzianum) and for the phosphorus experiment three doses of P were used, control (160 kg ha-1
of P), low P (80 kg ha-1
of P) and low P+
(80 kg-1 + Trichoderma harzianum). In both
experiments, the characteristics of ear height (ALTE), plant height (ALTP), relative Falker
chlorophyll index (IRC), stalk diameter (DIAMC), number of rows (NF), number of rows (NL)
and dry grain mass (MG) were evaluated. The results showed that the most efficient hybrids, in
an agronomic way, the nitrogen (urea) and phosphate (simple superphosphate) fertilizers at a
dose of 80 kg ha-1
of N and P (50% of the recommended dose) were 2M77, 2M80 and P4285
and the most responsive to the dose of 160 kg ha-1
of N and P (recommended dose) were
DKB390 and P3898. The inoculation of Trichoderma harzianum associated with a dose of 80
kg ha-1
of N and P promotes the increase in grain mass, in a specific way, in the hybrids
DKB390 and GNZ7280, with benefits of variable form in the different characteristics and its
use only indicated for these commercial cultivars

Abstract: Research efforts are underway to find suitable approaches to integrate water deficit tolerance
strategies in plants, which would eventually help them to suppress the negative effects caused
by water shortages. In this way, the use of biostimulant and/or bioprotective products can
represent an important tool in mitigating the water deficit and increasing the productivity of the
soybean crop. Based on this assumption, the present study was carried out with the objective of
identifying the effect of the bioprotector H2 Protector in the mitigation of water deficit in
soybean plants. For this investigation, an experiment was conducted between November 2021
and January 2022 in a greenhouse, located at the State University of Goiás, Ipameri unit. A
completely randomized design was used in a 2 x 5 factorial scheme with three replications, in
which the first factor refers to the presence or absence of the commercial product H2 Protector
and the second factor refers to the water levels applied to the plants (25%, 50%, 75%, 100% and
125% of the daily evapotranspiration). At 60 and 90 days after emergence, the morphological
variables and agronomic components of the crop were analyzed. The product H2 Protector
showed significant interaction only for the variables plant height and transpiration rate, in
relation to water deficit. The application of the fertilizer H2 Protector, in its entirety, did not
attenuate the damage caused by the water deficit. However, the application of H2 Protector may
favor the vegetative stage of soybean. Soybean susceptibility to water deficit was evident,
mainly plant development and crop production aspects, which were considerably affected by
water regimes.
