Productivity and Quality of Green Snap Beans Varieties Under Desertic Conditions in Northwestern Mexico
The agricultural activity in Caborca, Sonora, depends on fruit trees and vegetable production, and the main crops are grapes, olive, and asparagus. However, is necessary to evaluate other vegetables. An alternative is the green snap beans production. This vegetable can be harvested during the last week of November, when, good prices aare available in the market. The objective of this experiment was to evaluate seven green snap beans varieties with round pod. The experiment was on 24 Aug. The density used was 20 seeds per meter (about 60 kg·ha-1). The experiment was carried out during 2001 with commercial growers. The date of sow was distance between beds was 2.0 m and we used two rows with 36 cm of separation. In our experiment, we used a drip irrigation system. The first harvest was 67 days after the date sowing and it was for 28 days with seven cuttings. The varieties with more yield were Festina, Mercury, and Castaño with 771, 632 and 558 boxes/ha, (30 pounds/box), respectively. The control variety (Savannah) yielded only 345 boxes/ha. The pod quality distribution was 26%, 32%, 50%, and 15% for classification 1, 2, 3, and no commercial value respectively. The Savannah variety was the best pod color (dark green) and more yield during the last cutting. None of the varieties evaluated had problems of pest and diseases.
