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.

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.

Use of synthetic pesticides reduces the competitiveness of Kenyan snap bean pods due to stringent regulations by importers as a result of presence of chemical residues. This study was conducted to determine the effectiveness of local biopesticides in managing insect pests and diseases of snap beans. Field experiments were set up in farmer's field where Trichoderma spp. and Paecilomyce spp. and plant extracts from turmeric, garlic, ginger and lemon were applied weekly as foliar sprays. Plant extracts reduced the population of whiteflies and thrips by up to 58% and 41% while antagonistic fungi had a corresponding 30% and 18% reduction, respectively. Trichoderma spp. reduced severity of angular leaf spot (37.5%), rust (67%) and anthracnose (20.7%). Plant extracts and antagonistic fungi increased marketable pod yield by 25.6% and 17.3%, respectively. Results demonstrated that local environments are potential sources of biopesticides that can be exploited for integrated management of pests and diseases.

Vegetable production in the Caborca area is about 6500 ha ,and the main crops are asparagus, muskmelon, watermelon, and pea. However, our objetive was to evaluate the artichoke as a new crop for this area. We planted one 5-ha plot with `Esmerald'. The planting date was 18 Oct. 1996, and the distance between rows and plants were 1.0 m and 1.6 m (6250 plants/ha). During the first year of production, the first harvest was on 24 Mar. 1997, and the last harvest 10 May. There was a total of seven harvests, with a yields of 400 boxes/ha for table production and 23,000 heads/ha for industrial use. The was 497 dollars/ha, which is very low compared with other vegetables crops.

`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.

Chemical Pesticides

Snap bean farmers mainly rely on chemical pesticides to manage insect pests but the introduction of strict maximum residue levels (MRLs) by European markets poses a challenge to the use of pesticides. This has necessitated the search for alternative pest management options that do not result in harmful residues on produce. Therefore, this study was carried out to determine the efficacy of potassium salts of fatty acids as alternative to synthetic chemicals in management of snap bean pests. Field experiments were carried out in farmers’ fields in Mwea and Embu for two cropping cycles between July 2013 and January 2014. Potassium salts of fatty acids at 0.5%, 1% and 1.5% spray solution was compared with chemical pesticide confidor® (Imidacloprid) and farmers practice [Thunder® (Imidacloprid + Betacyfluthrin) and Karate® (Lambda Cyhalothrin). Population of thrips, whitefly, and yield of pest damaged pods, in addition to marketable pod yield was determined. Application of potassium salts of fatty acids at 1% and 1.5% significantly (P<0.05) reduced white fly and thrips populations by up to 54%. Weight of pest damaged pods was also significantly (P<0.05) reduced by up to 76% while the weight of marketable pod yield was significantly (P<0.05) increased by up to 112%. The results demonstrated that potassium salts of fatty acids are a viable alternative to synthetic chemical pesticides thereby enabling farmers to produce with acceptable residue levels that meet market requirements.

Snap bean insect pests, including the potato leafhopper, Empoasca fabae Harris, soybean thrips, Sericothrips variabilis Beach, bean leaf beetle, Ceratoma trifurcata Forster, and the Mexican bean beetle Epilachna varivestis Mulsant, were monitored in conventional and no-tillage snap bean plots during the 1981–1983 growing seasons. Plots were split for insecticide versus no-insecticide treatment. Insecticide sprays effectively reduced insect pest populations in both tillage regimes during all three years. Thrips population levels were consistently higher in untreated no-till plots compared to untreated conventional tillage plots. Densities of other insect pest species were variable across tillages over years. Surface damage to bean pods at harvest was greater in untreated no-till plots in two of the three years and similar the third year when compared to untreated conventional tillage plots. Insecticide treatment programs should reduce surface pod damage in the production of no-tillage snap beans.

Yield And Quality

Water pumping restrictions of high-quality irrigation water from underground aquifers is affecting vegetable production in Southwest Texas. There is a need to develop efficient deficit-irrigation strategies to minimize irrigation inputs and maintain crop profitability. Our objective was to determine how growth, yield, and quality of cantaloupe (Cucumis melo L. cv. `Caravelle') are affected by irrigation systems with varying input levels, including drip depth position and polyethylene mulch. Stand establishment systems used were containerized transplants and direct seeding. Field experiments were conducted on a Uvalde silty clay loam soil. Marketable yields increased in the order of pre-irrigation followed by: dry-land conditions, furrow/no-mulch, furrow/mulch, drip-surface (0 cm depth)/mulch, drip-subsurface (10-cm depth)/mulch, and drip-subsurface (30 cm depth)/mulch. Pooled across all drip depth treatments, plants on drip had higher water use efficiency than plants on furrow/no-mulch or furrow/mulch systems. Transplants with drip-surface produced 75% higher total and fruit size No. 9 yields than drip-subsurface (10- or 30-cm depth) during the first harvest, but total yields were unaffected by drip tape position. About similar trends were measured in a subsequent study except for a significant irrigation system (stand establishment interaction for yield. Total yields were highest for transplants on drip-subsurface (10-cm depth) and direct seeded plants on drip-subsurface (10 and 30 cm depth) with mulch.
