E-mail: [email protected] 1 RESUMO A salinidade restringe a exploração da maioria das culturas, tornando a atividade agrícola economicamente inviável. Nesse contexto, objetivou-se com o presente trabalho avaliar o crescimento, produção e qualidade da chicória (Cichorium endivia L.) submetida a diferentes condutividades elétricas da água (CEa) em condições hidropônicas. O delineamento experimental foi em blocos casualizados sob cinco níveis de CEa (0,34; 1,5; 3,0; 4,5 e 6,0 dS m-1). Avaliaram-se: altura de planta (AP), número de folhas (NF), massas de matéria fresca (MFPA) e seca da parte aérea (MSPA), produção relativa (PR), eficiência do uso da água (EUA) aos 20 e 25 dias após o transplantio (DAT) e o consumo hídrico (CH) em diferentes períodos. As maiores reduções por acréscimo unitário de CEa foram observadas para MFPA, da ordem de 5,93 e 8,53% e também para MSPA, de 5,42 e 7,77%, aos 20 e 25 DAT, respectivamente. Aos 25 DAT, sob a maior salinidade (CEa 6,0 dS m-1) as produções relativas de MFPA e MSPA foram de 52,59 e 58,10%. O uso de água com salinidade de até 6,0 dS m-1 pode ser empregada no cultivo de chicória em hidroponia, mesmo com redução na produção, porém sem efeitos depreciativos na qualidade visual do produto.

GROWTH OF ENDIVE USING BRACKISH WATERS UNDER HYDROPONIC CONDITIONS 2 ABSTRACT Salinity can restrict the exploitation of most crops, making agricultural activity economically unfeasible. In this context, the objective of this study was to evaluate the growth, production and quality of endive (Cichorium endivia L.) submitted to different electrical conductivities of water under hydroponic conditions. The experiment was carried out in a randomized block design under five levels of electrical conductivity of waters - ECw (0.34, 1.5, 3.0, 4.5 and 6.0 dS m-1). Plant height (PH), number of leaves (NL), fresh weight (SFM) and dry weight of the shoot (SDM), relative production (RP), water use efficiency at 20 and 25 days after transplanting (DAT) and water consumption (WC) in different periods were evaluated. In general, the highest reductions per unit increase of around 5.93 and 8.53%, ECw were observed for the SFM, and for the SDM, 5.42 and 7.77%, respectively at 20 and 25 DAT. At 25 DAT, under the highest salinity (ECw 6.0 dS m-1) the relative production of SFM and SDM were 52.59 and 58.10%. Water with salinity of up to 6.0 dS m-1 can be used in the cultivation of endive in hydroponics, even with reductions in growth and production, but with no depreciating effects on the visual quality of the product.

TECHNICAL FEASIBILITY OF JAPANESE CUCUMBER PRODUCTION SUBMITTED TO DIFFERENT IRRIGATION BLADES 2 ABSTRACT Water deficiency is usually the factor that most limits the productivity and quality of vegetables. In this scenario, irrigation appears as an important factor of production, besides promoting the maximum productivity and product quality. The objective of this work was to identify an adequate management of drip irrigation, with reduced pan, for the development and production of japanese cucumber in a protected environment. The experiment was carried out at the Experimental Farm of the Rural Federal University of Amazônia, county of Igarapé - Açu - PA. A randomized block design with five treatments and four replicates was used, with slides of 30, 60, 90, 120 and 150% based on the evaporation of a modified pan. It was observed that, in general, both the deficiency and the water excess negatively affected the analyzed variables. The best productivity and growth indexes were found in the 90% and 120% ECA slides and the highest water use efficiency obtained with the lowest irrigation depths. The maximum value was 2842.53 kg ha-1 mm- 1, found in the treatment with 30% ECA. Keywords: Cucumis sativus L.; drip irrigation; evaporation; water management

ABSTRACT The use of mini-cuttings is an option for obtaining sweet potato propagules of excellent quality. The objective of this research was to evaluate the production and quality of sweet potato roots propagated by mini-cuttings in different types of trays and ages of seedlings. Six treatments, resulting from the factorial 2x3, were evaluated: two types of trays (162 and 200 cells, with 31 and 18 mL of substrate per cell, respectively) and three ages of seedlings (39, 46 and 53 days after placement of mini-cuttings in trays), in a randomized block design, with five replications. Seedlings characteristics, production and quality of roots were evaluated. Higher number and dry weight of leaves per seedling were observed in the tray with 162 cells than in trays with 200 cells. The younger seedlings (39 days) had a lower number of leaves, dry weight of leaves, stem, roots ant total (leaves + stem + roots) than seedlings of other ages. There was no difference in root production depending on the type of tray, regardless of the age of the seedlings. For the 162-cell tray, the age of the seedlings did not affect the production of roots. On the other hand, for the 200-cell tray, higher roots production was observed on seedlings 39 days age compared to seedlings with 53 days. No differences were observed among the roots of different treatments for titratable acidity, and levels of sucrose, reducing sugars ant total sugars. It is recommended to avoid old seedlings, that is, it is recommended to use seedlings with a maximum of 43 days after planting of mini-cuttings for trays with 200 cells, while for trays with 162 cells no difference in root production was observed with the different ages of the seedlings.

Nutrient Solutions

Empiricism in the use of nutrient solutions is frequent. Several times the same nutrient solution is used to grow different species based only on morphological similarities. This practice may lead to nutritional imbalances, affecting not only the production but also the quality of the product due to an accumulation of nitrate. An experiment under hydroponic conditions - the NFT system - was conducted with the aim of evaluating the effect of the concentration of nitrogen in the nutrient solution on the production and on the nutrient and nitrate contents of rocket (Eruca sativa) salad leaves. The experiment was carried out in spring 2003, in a randomized block design and in a 4 x 3 factorial design, with four replicates. Four nitrogen concentrations in the nutrient solution (60.8; 121.6; 182.5; 243.5 mg L-1) and three rocket salad cultivars (Cultivada, Folha Larga and Selvática) were evaluated. Cv. Cultivada produced the tallest plants and the highest leaf fresh fitomass, not differing from cv. 'Folha Larga' in the number of leaves, leaf nitrate content, root dry fitomass and root fresh fitomass. An increment in NO3, N, Ca and P and a reduction in Mg, K and S occurred when the concentration of N in the nutrient solution was increased. Cultivation of cv. Cultivada at the concentration of 93 mg L-1 is the most recommended as it provides the highest yield and low nitrate content.

The recommendation of fertilization for zucchini (Cucurbita pepo) cultivation is usually made with no differentiation from the other cucurbit crops. Thus, there is a need to examine the doses of fertilizers used for zucchini production, as well as the suitability for cultivars, seasons, and cultivation regions. The aim of this study was to evaluate the influence of sulfur doses at topdressing fertilization and the supply of organic compost at planting on the production and quality of zucchini seeds. A total of eight treatments were studied in a randomized block design with a factorial scheme 4x2, corresponding to four sulfur doses at topdressing (0, 57, 114 and 173 kg ha-1 of S), in the presence (30 t ha-1) and absence of organic compost at planting. The fruits were harvested 62 DAT, and after harvest, the fruits remained in rest for 15 days in order to reach the uniformity of the physiological maturity of the seeds. The production characteristics evaluated were average fresh weight, diameter, dry weight and length of the fruits, fruit yield per plant, weight of a thousand seeds, number and seed weight. Regarding the seed quality, the percentage of germination, germination speed index, first count of the germination test, and electric conductivity, were evaluated. The supply of organic compost at planting had a positive effect on the production and physiological quality of the seeds of zucchini produced. The sulfur applied at topdressing improved the presence of the organic compost and also the production of seeds. Hence, it is recommended to apply 30 t ha-1 of organic compost at planting in association with 57 kg ha-1 of S at topdressing for higher seed yield and quality.

Solikin. 2018. Effect of nodes position on the growth and yield of stem cutting of Sambiloto (Andrographis paniculata). Nusantara Bioscience 10: 226-231. Plant propagation by cuttings can be done to produce relatively uniform quality of plant yield such as sambiloto (Andrographis paniculata (Burm.f.) ex Nees). The study aimed to determine the effect of nodes position on the growth and yield of stem cutting of sambiloto. The experiment was conducted in Purwodadi Botanic Garden in February-May 2017. The study used randomized block design with the treatment of nodes potition i.e. top, middle and base of stem cuttings. Each treatment was replicated three times. The results showed that the top stem cutting produced the highest cutting life, leaf area, leaf dry weight, root and generative organs dry weight. In contrast, the base stem cutting produced the lowest live cutting and plant growth.
