O cultivo em sistemas sem solo combinado com ambiente protegido e o uso de substrato proporciona algumas vantagens como: eliminação do uso de produtos destinados à desinfecção do solo, antecipação do início das colheitas, aumento da produção, proteção da cultura às condições meteorológicas adversas, ataque de pragas e doenças e melhores condições de manejo da cultura. O experimento teve como objetivo avaliar a produção e nutrição de quatro cultivares de morango em três sistemas de cultivo na Serra da Ibiapaba – Ceará. O experimento foi conduzido em esquema fatorial 3 x 4, em blocos casualizados, sendo três sistemas de cultivo dispostos em faixa (solo, hidropônico em calhas e em s a c o l a s ), com quatro cultivares de morangueiro (Oso Grande, Albion, Camarosa e Festival), com cinco repetições. No sistema hidropônico foi utilizado como substrato fibra de coco. No período entre a sexta e trigésima oitava semana após o transplantio, foi determinado o número e peso médio de frutos, produção por planta e produtividade. A partir do início do florescimento, foram coletadas a cada dois meses folhas para determinação dos teores de macro e micronutrientes. Os sistemas hidropônicos em calha e em sacolas aumentaram o número de frutos por planta, porém não aumentaram o peso médio de frutos. A produtividade do morangueiro cultivado no sistema hidropônico foi superior ao cultivo no solo. A cultivar Festival apresentou maior número de frutos em relação as demais cultivares nos sistemas hidropônicos. As cultivares Oso Grande e Festival destacaram-se quanto a peso médio de frutos e produtividade, respectivamente, sendo recomendadas para cultivo hidropônico para região da Serra da Ibiapaba. Com base nos teores de nutirentes na folha sugere-se ajustes nas concentrações de fósforo e magnésio na solução nutritiva utilizada no cultivo hidropônico do morangueiro.

Strawberry soilless cultivation combined with greenhouse and the use of substrate promotes some advantages such as: eliminating the use of products for soil disinfection, precocity, increased yields, better crop management conditions and crop protection against adverse weather conditions, pest attacks and diseases.. The objective of the study was to evaluate yield and nutrition of four strawberry cultivars in three cropping systems in Serra da Ibiapaba – Ceará. The experiment was conducted in 3 x 4 factorial design, randomized blocks, with three cultivation systems arranged in strips (soil, hydroponic in gutters and bags), with four strawberry cultivars (Oso Grande, Albion, and Camarosa and Festival) and five replications. Coconut fiber was used as substrate in the hydroponic systems. In the period between the sixth and thirty-eighth week after transplanting, the number and average fruit weight, yield per plant and yield were determined. From the beginning of flowering, leaves were collected every two months to determine the levels of macro and micronutrients. Hydroponic gutter and bag systems increased the number of fruits per plant, but did not increase average fruit weight. The strawberry yield in hydroponic cultivation system was superior to soil cultivation. Cultivar Festival presented more fruits than the other cultivars in hydroponic systems. The Oso Grande and Festival cultivars stood out as the average fruit weight and yield, respectively, and may be recommended for hydroponic cultivation for the region of Serra da Ibiapaba. Based on the leaf nutrient contents, it is suggested adjustments in concentrations of phosphorus and magnesium in the nutrient solution used in hydroponic strawberry crop.

Three orange cultivar trials have been established in Arizona, one at the Yuma Mesa Agricultural Center, Yuma, AZ and one at the Citrus Agriculture Center, Waddell, AZ. For the navel orange trial in Yuma, ‘Fisher’ navel continues to have the greatest yield, but is unacceptably granulated For the Waddell trial, the second year data has been collected, and suggests that ‘Fisher’ and ‘Beck- Earli’ are outperforming the other cultivars tested to date.

Three lemon cultivar selection trials are being conducted at the Yuma Mesa Agriculture Center in Somerton, AZ. Data from these trials suggest that ‘Limonero Fino 49’ selections may be a suitable alternative for the varieties most commonly planted in Southwest Arizona today. ‘Cavers Lisbon’ and ‘Villafranca’ might also be planted on an experimental basis

Four 'Lisbon' lemon selections, 'Frost Nucellar', 'Corona Foothills', 'Limoneira 8A' and 'Prior' were selected for evaluation on Citrus volkameriana rootstock. 1994-2002 results indicate that the 'Limoneira 8A Lisbon' and ‘Corona Foothills Lisbon’ are superior in yield and fruit size. Results for 2002-03 indicate that these cultivars as well as ‘Frost Nucellar’ have superior yield.

In a rootstock evaluation trial planted in 1993, five rootstocks, ‘Carrizo’ citrange, Citrus macrophylla, ‘Rough Lemon’, Swingle citrumelo and Citrus volkameriana were selected for evaluation using 'Limoneira 8A Lisbon' as the scion. 1994-2002 yield and packout results indicate that trees on C. macrophylla, C. volkameriana and ‘Rough Lemon’ are superior to those on other rootstocks in both growth and yield. C. macrophylla is outperforming C. volkameriana. For the second year in a row, ‘Rough Lemon’ trees performed similarly to C. macrophylla and better than C. volkameriana. ‘Swingle’ and Carrizo’ are performing poorly. In two other rootstock evaluation trials, both planted in 1995, C. macrophylla and/or C. volkameriana are outperforming other trifoliate and trifoliate-hybrid rootstocks under test.

Two orange cultivar trials have been established in Arizona, one at the Yuma Mesa Agricultural Center, Yuma, AZ and one at the Citrus Agriculture Center, Waddell, AZ. For the navel orange trial in Yuma, all the selections had improved yields in 2004-05. ‘Fisher’ navel continues to have the greatest yield, but is quite granulated. Of the rest in the Yuma trial, ‘Lane Late’ had the best quality and yield. For the Waddell trial, the fourth year data has been collected, and suggests that ‘Fisher’, ‘Beck-Earli’, ‘Chislett’ and ‘Lane Late’ are outperforming the other cultivars tested to date.
