Production of green snap beans is a good alternative for Caborca, Sonora, Mexico. This vegetable can be harvested during the last week of November when market prices are good, and has good adaptation, and high yield and pod quality. The objective of this experiment was to evaluate 11 green snap bean varieties. This experiment was carried out on a commercial field, where seed was sown on 25 Aug. 2003. Density was 20 seeds/m (60 kg·ha-1). In this trial, we used a drip-irrigation system on beds 2 m apart and two rows with 36 cm of separation per bed. The first harvest was 68 days after the sowing date and lasted for 20 days, with four cuttings during that time. The varieties with greater yield were `Castaño', `Festina', and `Landmark' with 541, 494, and 463 boxes/ha (>30 pounds/box), respectively. The varieties with low yield were `Espada' and `Leader' with only 52 and 75 boxes/ha, respectively. The control `Savannah' yielded 235 boxes/ha. The pod quality distribution was 20%, 35%, and 45% for first, second, and third classification, respectively. `Savannah' and `Festina' had the best pod color (dark green). None of the varieties evaluated had pest or disease problems.

New Crop

Vegetable production in the Caborca area is about 6500 ha, and the main crops are asparagus, muskmelon, watermelon, and pea. However during 1999, some growers tested green snap beans as a new crop for this area. The objective of this experiment was to evaluate five green snap beans with round podded (`Benchmark', `Landmark', `Jade', `Probe', and `Prosperity') and two densities (14 and 28 seeds/m) on subsurface drip irrigation system. The sowing was on beds of 2.0 m with two rows separated 60 cm. The date sowing was on 7 Sept. 1999. The first cutting were between 65 and 70 days after sowing in all varieties; in this case `Benchmark' was the earliest. The cumulative yield were 330, 140, 87, 63, and 20 boxes/ha (30 lb/box), respectively, in four harvests. On the other hand, the high population yielded 14.4% more than the low population. All varieties were damaged by frost that ocurred on 22 and 23 Nov. `Prosperity' was more susceptible to mosaic virus and `Benchmark' more tolerant. The pod quality distributions were 19.9%, 21.5%, 26.1%, and 21.0% for classes 1, 2, 3, and 4, respectively. We have not seen any important insect pests during this trial.

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.

`Blue Ridge' snap beans were planted with no fertilizer or banded rates of 560 kg ha-1 of a 10-4.4-8.3 fertilizer on soils with medium fertility in 1990 and 1991. Foliar applications of water soluble fertilizers containing nitrogen, phosphorus, and potassium were made at early bloom and in split applications at early bloom and repeated 10 days later. No response to fertilizer banded at planting or to foliar nutrient applications was found in snap bean yields or pod quality. Most fertilizer applications at planting increased plant size and lodging in 1990, but not in 1991. With the use of a rotation schedule and winter cover crops, snap beans showed no response to fertilization on soils of medium fertility.

Mexican production of vegetables under greenhouse conditions has been increased notably during the last year to about 1500 ha. The main crop in greenhouse production is tomato, but european cucumber is a potential crop due to high yield and quality, with a good price in the marketplace and a short growing season. The objective of this trial was to evaluate eight european cucumber varieties and to choose those with high yield and fruit quality, and disease resistance. The experiment was carried out at the experimental station (INIFAP-CIRNO). Greenhouse conditions were: polyethylene (8.0 mL), without temperature control; natural ventilation; and soil with electrical conductivity of 1.22 dS·m-1 and pH 7.96. Sowing date for seed was 15 Oct. 2004. Plant density was 3.78 plants per m2. The harvest period was 26 Dec. 2004 to 11 Mar. 2005, with an average of 10 cuttings. Varieties with highest yield were `Imanaol', `Bermejo', `Dominica', and `Kalunga', with 18.9, 15.2, 14.8, and 14.3 kg·m2, respectively. Fruit quality was excellent in all varieties; however, `Imanaol' had the highest percentage of size and fruit number. The main insect pest during the year was white fly (Bemissiasp.) and the most important disease was powdery mildew (Erishipecichoracearum).

Spring Sowing

The present paper evaluates the result of irrigation experiments carried out on snap beans sown in spring and summer and grown with and without irrigation. The experiments were run over the course of 12 years. In the average of 12 years, the yield was 2.8t ha-I for spring sown and 1.9 t ha-I in summer-sown plants without irrigation. The lowest level of profitable production, the 5.5t ha-I was reached twice in the case of spring sowing and only once in the case of summer sowing. Profitable yield production can be ensured only with regular irrigation and thus the yield may be increased by 4-5 times. In four of the twelve years we determined the canopy surface temperature of snap bean stands with and without irrigation. A Raynger II infrared remote thermometer determined the canopy surface temperature every day at 13.00 hours. The canopy temperature can well characterize the water supply of plant stands. This parameter may be used for describing the degree of drought and the water turnover of plant stands with different water supply. The positive values of foliage-air temperature differences (SDD) numerically express the degree of drought and the water supply of the crops. The results indicated that a 1 °C higher SDD value may cause 90-130 kg/ha yield loss.

Background: In Tunisia, water deficit and heat stress during the end of cycle are more frequent and causes significant yield losses. Selection of short cycle lines could be a good solution to escape the effect of heat and drought during the end of cycle. Furthermore, there is little published information on the effect of the sowing date on yield and its components in lentils. The aim of this study was to investigate the effect of the sowing date on yield and its components of some lentil lines. The best productive and early lines will be selected and therefore proposed for registration in the official catalog of plant varieties. The availability of these varieties to farmers could increase lentil production. Methods: Sixteen genotypes of lentil out of which 14 were advanced lines and 2 were checks varieties were used in this study. The field experiment was conducted during the 2017-2018 cropping season at Kef research station located in a semi-arid zone in north western Tunisia. Genotypes were sown on December 15th, 2017 and February, 7th, 2018. Seventeen agro-morphological parameters were recorded. Result: Based on agro-morphological analysis, lentil lines exhibited considerable genetic variability. Among the tested lines, L3 line seem to be the earliest lines. It showed high yield as well in timely and late sown dates. This line deserves more attention to develop short-cycle and high yielding variety.

Research on snap bean seed production is essential for this crop to compete against other species that have better production technologies. This study aimed to select a physiological quality evaluation test for snap beans to improve progeny selection strategies. The experiment was conducted in the Seed Analysis Laboratory at the Federal Institute of Goiano, campus Iporá-GO. Seed from thirteen progenies were evaluated for physiological quality from a breeding program conducted by the genetic breeding department of the State University of Goiás, campus Ipameri. Seeds were evaluated for moisture content, thousand-seed weight, biometry (length, width, and thickness), germination, seedling vigor classification, length and seedling dry mass, emergence in the field, and emergence speed index of seedlings in the field. The genetic variability in the evaluated characteristics indicated that genetic breeding can contribute to a better performance in snap bean seed physiological quality. The germination test, vigor classification, emergence, and emergence speed index of seedlings can be used to design strategies for snap bean population selection that produces more productive seeds.
