“…The variance between cultivars can be explained on the basis that, yield and quality of snap bean are affected by genotype of the variety (Nassar, 1986 andAmer et al, 2002). The same results were reported by Abdel-Mawgoud et al (2005) and Brunner et al (2014).…”

Poulista and Xera are the most important snap bean cultivars growing under El-Fayoum conditions, for both local market and export. Antioxidant substances are organic compounds, i.e., organic acid or hormones. Recent studies concentrated on the beneficial effects of these antioxidant substances to improve plants performance. Therefore, an experiment was carried out during the fall seasons of 2016 and 2017 in a private farm at El-Fayoum Governorate, Egypt to study the effect of 7 antioxidant substances, i.e., indole -3-acetic acid, indole -3-butyric acid, ascorbic acid, citric acid, salicylic acid, tartaric acid and oxalic acid as a foliar application, each at the rate of 500 ppm, on growth characters, green pods yield and pod qualities of Poulista and Xera plants. Seeds of both cultivars were sown in September; experimental design was spilt plot. Antioxidant applications were done after 20, 30 and 40 days from planting and plant samples were taken after 50 and 70 days for growth characters and for green pods yield and quality parameters, respectively. Results showed that Xera variety was the higher in pod length, pods weight/ plant -1 , chlorophyll a, b and total chlorophyll content in leaves and amino acid content in pods compared with Poulista variety. Moreover, Poulista variety was higher in plant height, carbohydrates content in stem and pods and amino acid content in stem compared with Xera cultivar.All foliar antioxidant applications significantly increased all growth characters, pods yield and pod quality and chemical composition of carotenoids, chlorophyll a, b and total chlorophyll, as well as, carbohydrates and amino acid contents in leaves, stem and pods of snap bean plants compared with the control treatment. The superior application was oxalic acid followed by ascorbic acid, respectively, while citric acid gave the highest content of amino acid in stem. The remarkable growth and production improvement in Xera or Poulista cultivar obtained when plants treated with oxalic or ascorbic acid 3 times (20, 30, 40 days) from planting at the concentration of 500 ppm.

“…Napoli cultivar was among the least productive in both systems. Higher yield values found in the conventional cultivation system are in agreement with Brunner et al (2014), who found, in na organic system in Puerto Rico, Panama, yields of marketable pods superior to those found in conventional system. They also agree with Portal et al (2018), who, studying genotypes of wild bean of indeterminate growth, in the same place, also found better yield performance in organic production system.…”

“…In a study with the production components of bush snap beans, in conventional and organic systems, Gomes et al (2017) observed that the cycle was shorter in the conventional system and that there was interaction between cultivars and cultivation systems, with the plants having greater development in the organic system, without affecting the yield of marketable pods. Brunner et al (2014), studied eight snap bean cultivars in an organic system and observed yield results ranging from 9.9 to 14.6 tons of pods per hectare.…”

Snap beans are one of the ten most consumed vegetables in Brazil, and there are few cultivars available in the Brazilian market. This study aimed to evaluate the seed yield of 20 snap beans genotypes under conventional and organic systems under Brazilian Cerrado conditions. Plant height, number of seeds per pod, weight of 100 seeds and yield were evaluated. For plant height and number of seeds per pod, the 20 genotypes were equal in the conventional cultivation system. In the organic system, the 20 genotypes formed two distinct groups regarding these variables. In the conventional system there were no significant differences between genotypes regarding the weight of 100 seeds, the mean mass in this system was 19.08 g, but there were differences in the organic system. Regarding yield, there was significant difference between the genotypes for both cultivation systems, organic and convetional. Production of snap bean cultivars in the organic system was shown as viable and promising. The genotypes Amarelo Japonês, Hab 1 and Tendergreen Improved stood out among the most productive in both systems.

“…Vaz et al (2017) studied 29 bush snap bean genotypes, from different countries of origin, under conventional cultivation, in Ipameri-GO, of which 19 are from the same study, and recorded the cultivars Contender, Jade, and Provider as the most productive (18 t ha -1 ). Brunner et al (2014) analyzed eight bush snap bean genotypes, in an organic system, in Puerto Rico and found that the cultivars Provider, Contender, Festina, and Jade were among the most productive, with a range from 10.90 to 14.60 t ha -1 . Andrade et al (2017) evaluated 25 bush snap bean accessions under organic cultivation in Londrina-PR; they found yields between 5.14 and 9.72 in the September-December season and between 7.02 and 11.07 t ha -1 in April-June.…”

Snap bean is a species widely cultivated in Goiás, in which cultivars of indeterminate growth are used in a staking system. Considering the high cost of staking and the unavailability of a workforce, there has been a demand for bush cultivars, but little is available on the market. In this sense, the present study was developed to evaluate, in 2016, under the conventional and organic cultivation systems, in Anápolis-GO, the behavior of 20 bush snap bean genotypes. The experimental design was randomized blocks, with 20 treatments and three replications. There was a significant interaction between genotypes and cultivation systems for vigor, average pod mass, number of pods per plant, and pod yield, evidencing that the types of cultivation, organic and conventional, interfered with the response of these variables. Although the Commodore Improved cultivar has excelled in pod yield in the conventional system, all genotypes were suitable for organic production. Hab 39, Improved Gold Wax, Kentucky Wonder Bush, Provider, Stringless Green, and Tendergreen genotypes are unsuitable for the conventional production system.
