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.

<p>ABSTRAK<br />Penggunaan varietas jahe yang responsif terhadap pemupukan dosis<br />rendah, diharapkan mampu meningkatkan efisiensi pemupukan dan<br />menekan pencemaran lingkungan. Penelitian dengan tujuan untuk<br />mengetahui respon lima aksesi jahe putih kecil terhadap pemupukan dosis<br />rendah telah dilaksanakan di Kebun Percobaan Cimanggu pada bulan<br />Agustus 2009 sampai Mei 2010. Lima aksesi jahe putih kecil dari daerah<br />marginal ditanam dalam polibag dan disusun menggunakan rancangan<br />acak kelompok yang diulang 3 kali. Setiap perlakuan terdiri atas 20<br />tanaman. Dua perlakuan yang diuji secara faktorial adalah, faktor I adalah<br />5 aksesi jahe putih kecil, yaitu (1) Ziof 0004, (2) Ziof 0007, (3) Ziof 0008,<br />(4) Ziof 0013, dan (5) Ziof 0014, dan faktor II adalah dosis pupuk, yaitu<br />(a) 50% dosis anjuran (200 kg/ha urea + 150 kg/ha SP-36 + 150 kg/ha<br />KCl), (b) 75% dosis anjuran (300 kg/ha urea + 225 kg/ha SP-36 + 225<br />kg/ha KCl), dan (c) dosis anjuran (400 kg/ha urea + 300 kg/ha SP-36 +<br />300 kg/ha KCl). Masing-masing perlakuan diberi pupuk kandang sebagai<br />pupuk dasar dengan dosis 20 t/ha. Pengamatan dilakukan terhadap<br />parameter pertumbuhan (tinggi tanaman, jumlah anakan, diameter batang,<br />dan jumlah daun), hasil dan serapan unsur hara N, P, dan K pada umur 4<br />BST dan 9 BST. Hasil penelitian menunjukkan bahwa masing-masing<br />aksesi memberikan respon yang berbeda terhadap penurunan dosis pupuk,<br />baik pada fase pertumbuhan maupun produksi tanaman jahe. Pengurangan<br />dosis pupuk sampai 25% tidak mengurangi produksi jahe, tetapi penurunan<br />dosis pupuk sampai 50% dari dosis rekomendasi menyebabkan penurunan<br />produksi jahe secara nyata. Komposisi unsur hara N, P, dan K yang<br />diserap berbeda pada setiap fase pertumbuhan tanaman.<br />Kata kunci : Aksesi, Zingiber officinale, pemupukan, pertumbuhan,<br />produksi</p><p>ABSTRACT<br />Response of five accessions of small white ginger to<br />fertilizers<br />The use of ginger varieties responsive to low fertilization dosages,<br />is expected to increase fertilizer use efficiency and reduce environmental<br />pollution. Research aimed at observing response of five small white ginger<br />accessions of low-dosage fertilization has been conducted in the Cimanggu<br />Experimental Station in from August 2009 through May 2010. Five small<br />white ginger accessions from marginal areas were planted in polybags.<br />The experiment was and arranged using a randomized block design was<br />repeated with 3 times replications.

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

ABSTRACT Knowledge of how climatic conditions affect plant morphophysiology is essential for understanding how to manage the growth cycles of different crops. The aim of this study was to evaluate the effects of the growing seasons in a semi-arid area on the morphophysiological variables of ornamental sunflower plants. The experiment was carried out in a randomized block design in a split-plot arrangement with four replicates. Six cultivars (‘Bonito de Outono Sortido’, ‘Sol Noturno’, ‘Sol Vermelho’, ‘Jardim Amarelo Alto’, ‘Girassol F1 Sunbright Supreme’ and ‘Girassol F1 Vincents Choice’) were evaluated in the main plots and two different growing seasons (GS) in the subplots (GS1 - warm climate and GS2 - mild climate). Evaluations of gas exchange, chlorophyll indices, and leaf surface area were carried out at the reproductive stage (R5.5). The cultivation of ornamental sunflowers in semi-arid regions was significantly affected by the growing season. Changes in gas exchange variables and the morphophysiology of ornamental sunflower plants in the two growing seasons reflected the high phenotypic plasticity characteristic of this species. The cultivation of ornamental sunflowers under semi-arid conditions in the growing season, when air temperature and solar radiation are high, could be limited due to elevated transpiration rates. Therefore, it is recommended that they are grown mainly during the moderate climatic season in semi-arid regions.
