Grapes are one of the more important fruit crops in northwest Mexico, mainly dedicated for the production of table grape, with the most important cultivar being `Superior Seedless'. The shortage and high cost of extraction of the water, infestation of nematodes, and salinity, are the main problems that limit the production in the region. The objective of the present investigation was to determine the productivity of `Superior Seedless' grafted on the rootstocks Harmony and Freedom. The present study was carried out in the INIFAP-Caborca Research Station in 2005, and consisted of 15 plants for treatment grafted to each rootstock. We used `Superior Seedless' in their own foot as control; watering was under a drip-irrigation system, and we used a completely randomized statistical design, where each plant was the experimental unit. Statistical differences were not observed in production among the two rootstocks (Freedom and Harmony), which yielded 2225 and 2112 boxes/ha, respectively (boxes of 10 kg) and an average of 1000 boxes/ha over the control. The quality (berry size and cluster weight) of the fruit on both rootstocks was superior to the control. They were no differences in the sugar content and the phonological stages (bud-break, flowering, and harvest time). In both rootstocks, we obtained 100% nematode control, a 35% savings of water consumption, and a 40% savings in fertilizer use.

Grape is one of the more important crops in northwestern Mexico (Sonora), especially for table grape. Although raisin production is a good option, it must be efficient and productive due to the problems of shortage and high cost of water, salinity, and nematodes. The objective of this research was the evaluation of `Fiesta Seedless' on Freedom rootstock for raisin production with different plantation densities. This study was carried out in the INIFAP Caborca research station in 2002. Four plant separations (1.0, 1.5, 1.7, and 2.0 m) were evaluated on furrows 4 m apart. Plants were grafted on Freedom rootstock in 1999. We also considered a control treatment (4 × 2 m on its own feet) and fertilized it with 80N–60P–80K. All experiments were carried out under the espalier training system with double crossbeam; watering was under a drip-irrigation system; and the statistical design was completely randomized. Statistical differences between the evaluated spacings were not observed, but all densities surpassed the control. Greatest yields were obtained with 1.5- and 1.7-m spacings, at 6.1 and 6.0 t·ha-1 of raisin, respectively, which were 2.2 t·ha-1 more than the control (3.8 t·ha-1). There were no differences in sugar content and harvest time, since all treatmens, including the control, were harvested at 24 °Brix. Freedom rootstock had 100% nematode control, 30% less water consumption, and was not fertilized.

The region of Caborca, Sonora, Mexico, is one of the main area producers of table grapes, in particular the cultivar Red Globe. However, the main problems in the region include shortage and high cost of water, nematode infestation, and salinity. The objective of the present research was to determine the behavior of `Red Globe' cultivated on the rootstocks Harmony and Freedom. This study was carried out in the INIFAP Caborca research station in the year 2002, and consisted of 10 plants for treatment (on each rootstock). When water was low, a drip irrigation system was used. There was a completely randomized statistical design. We observed no differences among the two rootstocks in the different phonological stages (budbreak, flowering, and harvest time). The results indicated statistical differences between the rootstocks. Yield was higher on Freedom rootstock, with 2120 boxes/ha (boxes of 10 kg), an average of 470 boxes/ha more than on Harmony rootstock. Freedom rootstock also improved the quality of the grape (better color, bigger size of berry, and clusters, and the foliage was also more developed with this rootstock). In both rootstocks, nematode control was 100%, 30% in water consumption, and no fertilizer was used.

In the Northwest of Mexico, grape is one of the main crops, specially for table grape (18,000 ha), the `Flame seedless' is one of the important cultivars. Some of the main problems present in this region is the shortage and high cost of the water, nematode and salinity. The objective of this investigation was to evaluate the effect of `Harmony' rootstock on `Flame seedless' for table grape. This study was caried in the INIFAP Caborca during 2001 cycle and consisted of ten plants of `Flame Seedless' on `Harmony' rootstock and ten control plants under the drip irrigation system, the statistical design used was completely randomized. The results obtained observe not negative effect for the `Harmony' rootstock on the phenology of `Flame seedless' (budbreak, flowering and color develpment). The effect was positive since harvest date advanced in 4 days (4 June), where as the control harvest was in 8 June, as far as color were no differences, because both treatments colored well, as far as quality this was better on rootstock than that was not grafted (greather berry size and cluster uniformity). The yield was 1,200 boxes/ha when we used rootstock, 335 boxes more than control and obtaining a saving cost of 100% in the nematode control and 30% in water consumption.

Yield And Quality

The strawberry cultivation is an important economic activity in the Rio Grande do Sul State, Brazil, however the number of offered cultivars to the growers is reduced. The yield and quality of strawberry (Fragaria x ananassa Duch.) cultivars Camarosa, Galexia, Earlibrite, Festival, Plarionfre and Sabrosa was evaluated under the climatic conditions of Pelotas, Rio Grande do Sul State. We determined the number, mass, total soluble solids (TSS ºBrix), total titratable acidity (TTA), antocianin level and fresh fruits produced in an experimental unit. We also determined the production of fruits per hectare and per plant. The statistical design used in the experiment was of completely randomized blocks with 6 treatments (cultivars) and 4 replicates where the experimental unit was composed of 8 plants. The harvest began in the first half of August, extending to the second half of December, totalling 20 weeks. Plarionfre, Earlibrite and Festival cultivars showed higher production from the first half of October until the end of the first half of November. Camarosa reached higher productivity, mass of plants and fruit weight. There were no differences between the evaluated cultivars in the levels of TSS, antocianin, ATT and pH during the period of evaluation.

Cucumis Melo L

The influence of different watering regimes and of potassium applications on the quality of the melon cultivar «Pielde Sapo» was studied over a two-year period (1995 and 1996). The statistical design was a split-plot with four replications,where irrigation was the main factor and applied potassium was the secondary factor. Water levels were determinedaccording to the watering needs (NRc) calculated on the basis of crop evapotranspiration. Four irrigationtreatments were tested: 1.25 NRc; 1.00 NRc; 0.75 NRc and 0.50 NRc. Two potassium treatments were applied: K0 (0UF) and K1 (375 UF K2O in 1995 and 2 L ha–1 of a commercial product for spraying 20% of K2O in 1996). The potassiumdoses tested did not significantly influence any of the quality parameters studied except for flesh firmness inthe placenta area in 1995. Both in 1995 and 1996, the water deficit significantly reduced fruit size and flesh thickness.The severe water restriction caused a strict decrease in the percentage of fruits with recorded weight above 2.5kg. However, the weight percentage of the placenta plus the seeds in relation to the whole fruit, and the sugar content,both increased significantly in water deficient treatments. In 1995, skin thickness decreased with less irrigation whileflesh firmness increased. Following quality concerns, and in order to obtain large fruits with appropriate levels ofsugar, it is advisable to provide water amounts that meet the crop’s watering needs

A relevant improvement of the cultivar conditions of Rosmarinus officinalis L. in desert areas was achieved by a specific combination between irrigation system and soil conditioner. A drastic reduction of water employment was obtained without affect the quality of the plants, determined by monitoring growth parameters and essential oil characteristics. In particular, the effect of surface and subsurface drip irrigation systems and different soil conditioners on growth parameters, yield, and essential oil constituents of rosemary plant was assessed. Field experiments at the Agricultural Research Station (Al-Adlya farm), SEKEM group Company, El-Sharkiya Governorate, Egypt, conducted over the two seasons revealed the effectiveness of the subsurface irrigation system in obtaining better performances, especially in terms of water saving. The combination of subsurface irrigation and the conditioner Hundz soil with bentonite showed the maximum mean values of growth characters compared with other soil amendments during both seasons. The possibility to employ a water-saving irrigation system as the subsurface one without any drawback in the resulting plants was also explored in terms of molecular composition. GC-MS analysis of the essential oil extracted from plants growth under different irrigation conditions revealed a comparable composition in both cases. The goodness of the most performing system was also confirmed by the comparable yield of the essential oil.

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.

Field trials were carried out to test the effect of nitrogen fertilization on the growth, stalks and juice yield, sugar content and ethanol production of sweet sorghum. The experiments were carried out on winter 2013 in the Domonstration Farm of the Faculty of Agriculture, University of Khartoum, Shambat and Experimental Farm of the Soba Research Station for Reclamation of Saline and Sodic soils. The treatments comprised the addition of nitrogen fertilizer (urea) at three levels (0, 43 and 86 Kg N ha-1) and two sweet sorghum genotypes (Baladi and RSSS.11), arranged in randomized complete block design replicated 4 times. Results indicated that there were significant (P ≥ 0.05) differences between genotypes in stem diameter at Soba location, stalk height and leaves area at Shambat location, number of green leaves per plant, stalk juice and ethanol yield in both locations. With the genotype RSSS.11 generally superior over genotype Baladi. Nitrogen fertilization increased significantly (P ≥ 0.05) number of green leaves per plant and leaves area at Shambat location and plant height and juice and ethanol yield in both locations. With the Soba location recorded the highest values over Shambat location and 86 kg N ha-1 recorded the highest ethanol yield (255.6l h-1).
