The density of herbaceous crops creates a suitable environment to produce pathogens in the soil that intensify the attack of pathogens traditionally controlled by disinfectant, which are mostly prohibited and unlisted because of their toxicity. Grafting is an alternative technique to enhance abiotic stress tolerance and reduce root diseases due to soil-borne pathogens, thus enhancing crop production. This research study was conducted during the crop season of 2017 and 2018 in order to investigate the interactive effect of different grafting techniques of hybrid scion onto local rootstocks on plants survival, plant phenological growth, fruit yield and fruit quality under a controlled environment. The hybrid cucumber was also planted self-rooted. The cucumber (Cucumis sativus L.) cv. Kalaam F1, Syngenta was grafted onto four local cucurbitaceous rootstocks; ridge gourd (Luffa operculate Cogn.), bitter gourd (Momordica charantia L.), pumpkin (Cucurbita pepo L.), bottle gourd (Lagenaria siceraria (Molina) Standl.) using splice grafting, tongue approach, single cotyledon and hole insertion grafting techniques and self-rooted hybrid cucumber under greenhouse conditions. The experimental results indicated that all local cucurbitaceous rootstocks showed a high compatibility with hybrid cucumber scion in the splice grafting method compared to other grafting and non-grafted methods. Lagenaria siceraria rootstocks were found highly compatible with cucumber cv Kalaam scion which gave significantly maximum plant survival rates (95%) due to high sap contents, high SPAD value, better vegetative growth and maximum fruit yield when compared with other rootstocks by employing the splice grafting method followed by tongue approach, single cotyledon and hole insertion grafting while the fruit quality of all rootstocks was observed to be similar. The non-grafted cucumber cv. Kalaam F1 showed significant results of plant vegetative growth, fruit development and fruit quality and encountered grafting methods while the lowest result were associated with the hole insertion grafting method in all scion/rootstock combinations. The grafted plants have no significant effect on cucumber fruit dry matter and fruit quality while the fruit mineral compositions (N, P, K, Ca and Mg) were higher among grafted and non-grafted plant fruits. The results indicate that grafting hybrid cucumber onto four local cucurbitaceous rootstocks influenced growth, yield and fruit quality. Grafting can be alternative and control measure for soil-borne disease and to enhance cucumber production.

Neste cenário, a irrigação surge como um importante fator de produção, além de promotor da máxima produtividade e da qualidade do produto. O objetivo deste trabalho foi identificar um manejo adequado da irrigação por gotejamento, com minitanque evaporimétrico, para o desenvolvimento e produção do pepino japonês em ambiente protegido. O ensaio foi realizado na Fazenda Experimental da Universidade Federal Rural da Amazônia, município de Igarapé – Açu/PA. Utilizou-se o delineamento em blocos casualizados com cinco tratamentos e quatro repetições, aplicando-se lâminas de 30, 60, 90,120 e 150% baseadas na evaporação do minitanque. Observou-se que de modo geral, tanto a deficiência quanto o excesso hídrico afetaram negativamente as variáveis analisadas. Os melhores índices de produtividade e crescimento foram encontrados nas lâminas de 90 e 120% da ECA e a maior eficiência do uso da água, obtida com as menores lâminas de irrigação, sendo o valor máximo, de 2842,53 kg ha-1 mm-1, encontrado no tratamento com 30 % da ECA.   Palavras-chave: Cucumis sativus L.; evaporação; gotejamento; manejo de água.     RODRIGUES, T.C.A.; LIMA JÚNIOR, J.A.; DE MELO SOUZA, R.O.R.; OLIVEIRA NETO, C.

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

Physiological Quality

The human consumption of vegetables in different parts of the world is quite high, among them tomato stands out on a larger scale and not so far, also is cucumber, both with great economic importance. Due to the problems regarding the vigor of many seeds, techniques that seek to improve the establishment of the seedlings in a uniform way have been implemented. One technique is the osmotic conditioning to which the seeds are submitted, for which compound solutions such as polyethylene glycol or potassium nitrate can be used, with which very satisfactory results are obtained under laboratory and field conditions The objective of this investigation was to evaluate the effect of different doses and osmotic solutions on the physiological quality of seeds of tomato (Solanum lycopersicum L.) and cucumber (Cucumis sativus L.) in laboratory and field conditions. The evaluated variables were germination percentage, germination speed index, root length and emergence of seedlings. The tomato seeds were conditioned with PEG-6000 (-0.2, -0.4, -0.6 and -0.8 Mpa) and stored for a 30 days period, and as for the cucumber seeds with PEG-6000 (-0.2 and -0.1 Mpa) and with KNO³ (100 mg and 300 mg) with a storage period of 45 days. It is concluded that, in tomato seeds, germination did not present statistical differences, however, the variables referring to vigor were favored with the conditioning in the presence of PEG-6000 with the (-0.2 Mpa) concentration, while in cucumber seeds the germination percentage was better using PEG 6000 compared to nitrate, while for vigor variables it behaved better in the presence of a concentration of (-0.2 Mpa) of PEG.
