Morphological and physiological responses of açaí seedlings subjected to different watering regimes
Provedor de dados: 91
Autores: Silvestre,Walter V. D.; Pinheiro,Hugo A.; Souza,Rodrigo O. R. de M.; Palheta,Lenilson F.
ABSTRACT Seedlings of açaí obtained from plant material native to floodplains (from Laranjeira and Muaná) and adapted to upland areas (cv. BRS-Pará and ecotype Hideo) were cultivated between March and October 2013 in a greenhouse, to test the hypothesis that water requirement for seedling production varies according to the origin of plant material. The seedlings were subjected to watering regimes corresponding to 40, 70, 100 and 130% of field capacity. Regardless of plant material, the production of vigorous seedlings was feasible only under irrigation of 100 and 130% of field capacity. The seedlings produced under 130% of field capacity showed higher plant height, stem diameter, number of leaves, total leaf area, leaf and root biomass, total plant biomass...

Development, yield and quality attributes of sugarcane cultivars fertigated by subsurface drip irrigation
Provedor de dados: 91
Autores: Silva,André L. B. de O.; Pires,Regina C. M.; Ribeiro,Rafael V.; Machado,Eduardo C.; Blain,Gabriel C.; Ohashi,Augusto Y. P.
ABSTRACT The present study aimed to evaluate the development, yield and quality of four sugarcane cultivars fertigated by subsurface drip system. The experiment was carried out in Campinas-SP, Brazil, from January 2012 to November 2013, with the cultivars SP79-1011, IACSP94-2101, IACSP94-2094 and IACSP95-5000 subjected to daily irrigations. The irrigations depths were applied to bring soil moisture to field capacity. Soil moisture was monitored using soil moisture probes. Samples were collected along the crop cycle in order to evaluate crop development and yield, at the end of the first and second ratoons. Stalk height showed good correlation for the estimation of crop yield, with R2 equal to or higher than 0.96. The cultivar IACSP95-5000 showed the...

Permanent wilt point from two methods for different combinations of citrus rootstock
Provedor de dados: 65
Autores: Ferreira,Rivani Oliveira; Souza,Luciano da Silva; Nascimento,Marilza Neves do; Silveira,Felipe Gomes Frederico da.
ABSTRACT: Considering that water is extremely important in agricultural production, but with restricted availability in some Brazilian regions, this research sought to identify the water limit for the rootstocks: Cleóptra tangerine (Citrus reshni hort. Ex Tan), Volkamer lime (Citrus Volkameriano Pasquale), Citrandarin ‘indio’ (TSK X TRENG 256), Santa Cruz Rangpur lime (Citrus × limonia) and Sunki Tropical tangerine (Citrus sunki HORT. EX TAN) grafted orange ‘Pera’ (Citrus sinensis), obtained by two methods: the traditional method of determining the permanent wilting point described by SHANTZ &amp; BRIGGS (1912) recovery of plants with saturated environment and by irrigating recovery method. The experimental design used was in a completely randomized design...
