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

O objetivo foi avaliar o efeito do déficit hídrico em diferentes fases do cultivo da pimenteira na eficiência de uso de água, na produtividade e na qualidade da pimenta ‘Tabasco’ cultivada em ambiente protegido, durante os meses de setembro de 2009 a julho de 2010, no município de Piracicaba-SP. O delineamento foi em blocos casualizados, com lâminas de irrigação de 40, 60, 80 e 100% da evapotranspiração da cultura (ETc), inicializadas nas fases vegetativa e de floração. O déficit de irrigação influenciou a produtividade da pimenta e o mesmo não foi observado para a qualidade física da pimenta. A eficiência do uso da água da pimenta Tabasco não foi influenciada pelo déficit. Entretanto, o déficit hídrico inicializado na fase de floração permitiu economia de água de até 50,1% de água no ciclo de 208 dias após transplantio.Palavras-chave: Estresse hídrico, Capsicum frutescens, produtividade e qualidade do fruto.MARINHO, L.

N.WATER DEFICIT APPLIED IN VEGETATIVE AND FLOWERING STAGE OF ‘TABASCO’ PEPPER IN GREENHOUSE2 ABSTRACTThe scarcity of water resources in Brazil has driven the management of demand for more efficient irrigation in farms in order to reduce water consumption and make its use more efficient. The objective of this study was to evaluate the water deficits’ effect at the vegetative and flowering stages of pepper in water use efficiency, yield and quality of pepper cv. 'Tabasco'(Capsicum frutescens) grown in a greenhouse from September 2009 to July 2010. The experiment was conducted as randomized block design with irrigation levels of 40, 60, 80 and 100% of Crop Evapotranspiration (ETc), beginning at vegetative and flowering stages. There was a significant effect of full and deficits irrigation started at vegetative and flowering stages on the fruit number per plant, and the linear model was the best fitted. The average of mass fruit per plant did not vary with the deficit, not even with the start up times. The deficit irrigation affected pepper productivity, yet it was not observed on the physical quality of fruits. The deficit irrigation (40% ETc) beginning at flowering stage allowed savings of up to 49.8% in water consumption in a cycle of 208 days after transplanting.Keywords: water stress, Capsicum frutescens, productivity and fruit quality.

The Indo-Gangetic plain (IGP) is an environmentally susceptible, communally momentous and economically tactical sphere of India where landscape, ground water and soil fertility are threatened by climate change. An increasing water scarcity for rice in the irrigated IGP is urging farmers to espouse water saving technologies such micro irrigation. Rice growing with drip irrigation may substantially reduce irrigation water requirement of rice. In order to make assessment of drip irrigation in rice, a field experiment was carried out at Pantnagar, Uttarakhand in 2017. Rice was established by Direct Seeding in conventional and drip irrigation treatments. The treatments were laid with drip irrigation at 50, 75 and 100% CPE on each 2 and 4 days interval. Two conventional irrigation practices (i.e. absolute control and farmers’ practice) were also included in the study. The experiment was laid out in randomized block design with four replications. Compared with farmers practice, (transplanted and flooded) drip irrigation at 100% CPE on two days interval produced taller shoots and higher yield attributes of rice crop. Rice grown in drip irrigation was found more grain yield than farmers’ practice. Among drip irrigation, 100% CPE on 2 days gap (T5) recorded 45% higher grain yield (5800 kg ha-1) than farmers practice. Similarly, T5 treatment was higher content and uptake of nutrient. However, treatments T3 (50% CPE on 2 days gap) followed by T7 (75% CPE on 4 days interval) had higher water use efficiency. Result, further revealed that fertilizer use efficiency of T5 treatment was found to be higher (23.2 kg grain per kg fertilizer applied). Hence, rice is scheduled with drip irrigation at a tune of 100% CPE on 2 days interval can benefit over sustaining the direct seeded basmati rice productivity. However, there is a demand to examine these benefits of drip irrigation in rice in relation to the viability of adoption by farmers.

The Effect of Branch Pruning and Mycorrhiza on Production and Seed Quality of Cucumis sativus L. The purpose of this study was to obtain the best branch pruning, with or without mycorrhiza application, in order to increase the production and quality of cucumber seeds. Pruning the branch at the beginning of cucumber growth is expected to delay fruit formation and support good vegetative growth. This research was carried out in the PT. Primasid Andalan Utama seed production area in Kalibeji Village, Tuntang District, Semarang Regency, Seed Technology Laboratory and Plant Physiology Laboratory, Faculty of Agriculture and Business, Satya Wacana Christian University. This study was conducted by the split-plot randomized complete block design with 2 factors. The main plot consists of 2 levels, namely control/without mycorrhiza (M0) and mycorrhiza application (M1). Pruning the branches as the subplots consist of 4 levels, were pruning to the second, third, fourth and fifth branches of the cucumber plant (P1, P2, P3 and P4). DMRT was used to differentiate the significance of the treatment. The results showed that mycorrhiza application increased the percentage of root infections. The pruning to the fifth branch (P4) is the best; in control without mycorrhiza (M0P4) increased for the number of fruits, the seed weight per plant, and the germination simultaneously; whereas in mycorrhiza application (M1P4) increased the number of fruits and the seed weight per plant.  It is also observed that the pruning to the second branch (P1) increased the weight of 1000 grains, the speed of germination and the simultaneous of germination; both with and without mycorrhiza application.

We aimed to evaluate the effects of different irrigation depths with saline water on growth, yield, water-use efficiency, and fruit quality of ‘Pérola’ pineapple plant grown in the semi-arid of Bahia state. The experiment was carried out in a randomized block design with five treatments which represented the irrigation depths: 100% of crop evapotranspiration (ETc) with irrigation water of 0.75 dS m-1 in electrical conductivity (ECiw); and 50, 75,100, and 125% of ETc with water of 3.6 dS m-1 in ECiw. Pineapples were grown under field conditions watered by drip irrigation in which pressure compensating emitters had 8 L h-1 flow rate. We observed that the irrigation depth 100% of ETc with water of 0.75 and 3.6 dS m-1 in ECiw provides higher pineapple yields under the semi-arid conditions of this study, and the chemical quality of the fruits are up to commercial standards, except when applying 125% of ETc with water of 3.6 dS m-1 in ECiw.

Soil moisture conservation, proper irrigation scheduling and nutrient management are crucial for sustainable cucumber production. A field experiment was set up over two years (2018 and 2019) to investigate the effects of irrigation frequency, black polyethylene mulching, and nitrogen fertilization on cucumber yield, water use efficiency (WUE) and nutrient use efficiency (NUE) at Ikole-Ekiti, Nigeria. The experiment was a 3 x 2 x 2 factorial in a randomized complete block design (RCBD) with a split-plot arrangement and the main plot as drip irrigation frequency: twice per week (I4), three times per week (I5), and four times per week (I6), while the sub-plots were nitrogen fertilization; (no fertilizer, N0 and 180 kg/ha urea, N180) and mulching (no mulch, NM and mulch, M). The highest yield (8.39 and 8.51 t/ha) with the best WUE was obtained from treatment I4MF (F, fertilization), while the lowest (5.81 and 5.79 t/ha) was obtained from I6MF for the respective years. The combination of variables significantly (P<0.05) influenced cucumber yield, WUE, and NUE, and significant correlations were obtained (r=0.87** and 0.85**) between WUE and fruit yield for the study years. The treatment I4MF therefore, could successfully be adopted to reduce water and fertilizer application for improved cucumber yield in the field.

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.   Palavras-chave: Cichorium endivia L., cultivo sem solo, salinidade.     ALVES, L.

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.   Keywords: Cichorium endivia L., soilless cultivation, salinity.
