The suitability of the spatial arrangement of soybean is a tool capable of promoting better use of the agricultural environment, allowing the crop to express its yield potential. Therefore, the aim of this study was to evaluate different implementation systems with and without an increase in the plant population of soybean with indeterminate growth habit variety cultivated in the Brazilian Cerrado. The experiments were performed in the 2013/14 and 2014/15 seasons in Rio Verde, Goias state. The experimental design was randomized blocks with four replication in a 4x2 factorial scheme. The treatments presents four implementation systems (traditional, reduced, double rows and crossed) associated with two populations of BMX Potência RR® (recommended and increased by 33%) with presented indeterminate growth habit. The results indicate that the reduced system has an adoption potential for soybean with indeterminate growth habit. The increase in the plant population in the 2013/2014 season, increased 20% of soybean yield in relation to the recommended population, proving to be a promising technique since it considerate the costs involved.

Tomato Genotypes

The cultivation of hybrid tomatoes, intended for fresh consumption, with a determined growth habit, and without support, is an alternative that has a lower production cost. The research aimed to evaluate the productivity and economic viability of different tomato genotypes, with a determinate and indeterminate growth habit. The experimental design was in completely randomized blocks. Ten hybrids and a variety were grown in 2016, and nine hybrids, and a variety in 2018, with a spacing of 0.5 meters between plants. Harvests were carried out in four periods in 2016, at 72, 82, 97, and 105 days after transplanting (DAT); and in 2018 at 81, 87, 97, and 111 DAT. After harvesting, the gross value of production and profit were quantified. The hybrids that obtained the highest production per plant in 2016 were Gabrielle (6,010 kg), with support; Thaise (5.529 kg); and N901 (5.003 kg). In 2018, Dominador and Thaise hybrids had the highest production, with 4.109 and 3.961 kg per plant, respectively. The gross value of tomato production in 2016 was higher than in 2018 for all hybrids and variety, except for Dominador hybrid. Hybrids with a determined growth habit and conducted without support are a profitable alternative to produce tomatoes intended for fresh consumption, especially the hybrid Gabrielle, which had the highest production. The economic viability of hybrids grown without support is superior to all hybrids with support.

ABSTRACT Protected cultivation has increased over the years. More studies on the benefits of using photoselective agrofilms are necessary. The choice of material to cover the greenhouse is a decisive factor for crop development and production. The aim of this study was to evaluate the effect of diffuser and blue-colored agrofilms on the production of different tomato cultivars of indeterminate growth habit under NFT hydroponic system. A completely randomized design in a 2x3 factorial scheme (two environments and three cultivars) was used: two agrofilm types (blue and diffuser) and 3 cultivars (Monterrey, Arendell and Totalle). Each plot consisted of 30 plants per treatment, with four replicates. Commercial tomato seedlings of indeterminate growth habit grafted on rootstock cultivar (Shincheonggang) were used. During the experiment, the electrical conductivity, intensity of radiation inside the greenhouse, gas exchange, soluble solids, lycopene content, pH and fruit production were evaluated. We concluded that the amount of radiation transmitted through the diffuser favors an increase of about 18% in gas exchange, 12% in lycopene content and 9.4% in tomato crop production.

Plant growth habit is an important trait. Our objective was to identify RAPD markers linked to major gene for indeterminate growth habit using bulked segregant analysis in an F2 population from a bean cross Chichara (indeterminate growth habit × PC-50 (determinate growth habit). A total of 132 RAPD primers (600 RAPD primer screened) showed polymorphisms between bulked DNA derived from indeterminate and determinate plants. All markers showed coupling linkage with indeterminate growth habit. RAPD markers of A-8, A-17, C-7, C-15, D-4, D-5, F-6, F-16, G-9, H-3, H-20, and I-7 were 2.2 cM distant from the gene for indeterminate growth habit. Markers of B-7, B-16, B-17, C-8, E-1, F-1, F-20 and H-l9 primers were 4.6 cM distant from the gene for indeterminate growth habit.
