The cultivation of roses occupies a special place in the flower production of Brazil, the concern with the quality of the buds being intimately related with the appropriate supply of water and nutrients to the plant. With the objective of evaluating stem and bud quality the rose variety 'Osiana' was cultivated in a greenhouse using different irrigation water depths based on fractions of pan evaporation (0.25, 0.50, 0.75, 1.00 and 1.25). The experimental design consisted of total randomized blocks with five replications and five treatments. There is a linear tendency of increasing the length and diameter of the stems and the length and diameter of the buds with increasing irrigation water depths.

ABSTRACT Crop strategies focused on the rational use of water are required in semiarid regions. Thus, the objective of this work was to evaluate the physiological quality of maize seeds produced under soil water deficit conditions. Five irrigation water depth were established, based on the field capacity (100, 85, 70, 55 and 40%), to control the available water for two maize hybrids (2B-587 and DKB-390). A randomized block design was used, with a split-plot arrangement and four repetitions. The plots consisted of irrigation water depths, and the subplots consisted of maize hybrids. The seed water concentration, germination, and vigor were determined after the harvest, using data from first germination counting, seedling emergence, germination speed index, seedling length, and accelerated aging, electrical conductivity, and modified cold tests. The maize hybrid DKB-390 showed better physiological potential under the soil water deficit conditions evaluated. The irrigation water depths lower than 70% of field capacity resulted in decreases in soil water contents and affected negatively the physiological quality of the maize seeds produced.

The objective of this study was to evaluate the effects of the biofertilizers (common and enriched) in substrate irrigated with saline waters on the quality of the seedlings evaluated by the phytomass from yellow Passiflora edullis. In this sense, an experiment was carried in a greenhouse at the Center of Agricultural Sciences and Biodiversity CCAB/UFCA, Crato-CE, from October/2017 to March/2018. The substrate used was a material of the first 20 cm to depth of a Red Yellow Latosol. The experimental design was completely randomized in a factorial scheme of type 5 × 3, with three replications, referring to the electrical conductivity values of the irrigation water: 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1, in the soil without the bovine biofertilizer; in treatments with common biofertilizer and, evaluated in the soil with enriched biofertilizer, conditioned in black polyethylene bags with it a maximum capacity of 5.0 kg, totaling 60 treatments. The fermented bovine biofertilizer after dilution in non-saline and non-chlorinated water (0.5 dS m-1), in the proportion of 1:3, was applied only once to 10% of the substrate volume, two days before sowing. The salinity increase of the irrigation water affected negatively the phytomass production, but with less intensity in the treatments with enriched biofertilizer. The enriched and common biofertilizer provided higher growth and consequently higher phytomass production of passion fruit seedlings in relation to the soil without the respective input, independently of the level of salinity of irrigation water.

An experiment was carried out in a greenhouse, from march to april/2018, in Crato-CE to evaluate the effects of biofertilizers (common and chemically rich) in substrate irrigated with different saline compositions on phytomass production of yellow pepper seedlings, success variety (952). The experiment was developed using a material or substrate from the first 20 cm of a Red-yellow Latosol. The experimental design was completely randomized in a 5x3 factorial scheme, with three replications referring to the electrical conductivity values of the irrigation water: 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1 in the soil without the organic input; with common biofertilizer, and in soil with rich biofertilizer, totalizing 45 treatments, packed in black polyethylene bags with a maximum capacity of 3.0 kg. The biofertilizer, after dilution in a 3:1 ratio, was applied only once to 10% of the substrate volume two days before sowing. Irrigation with saline water affected the morphology and quality of yellow pepper seedlings (cv. Success) but with less intensity in the treatments that received the common and rich organic inputs, respectively.

ABSTRACT The great solar radiation in the Brazilian semiarid region, combined with an adequate irrigation management, favors fruit production and quality of crops that were adapted to this region. The objective of this work was to evaluate the fruit quality of two apple cultivars grown in the Sub-Mid São Francisco River Valley under different irrigation water depths. A complete randomized block experimental design in a split -plot arrangement with five replications was used. The plots consisted of four irrigation water depths (ID) (60, 80, 100 and 120% of the reference evapotranspiration - ETo), the subplots consisted of two apple cultivars (C) (Julieta and Princesa) and the sub-subplots consisted of fruit positions in the tree canopies (FP) (east and west sides). The soluble solids content (SS), titratable acidity (TA), SS/TA ratio, pulp firmness (PF) and fresh weight (FW) of the fruits were evaluated. The factors evaluated showed no triple interaction between the evaluated factors, however, the SS and TA were significantly affected by them; the interaction between ID and C significantly affected the PF; the interaction between ID and FP significantly affected the PF, SS/TA ratio and FW; and the interaction between C and FP significantly affected the SS/TA ratio. The increase in water depth increased the fruit size of both cultivars, without compromising the post-harvest quality. The cultivar Princesa presented the best results regarding SS, TA, PF and FW, however, both cultivars had organoleptic characteristics within the recommended standards for commercialization. The fruits harvested on the west side presented better post-harvest quality.

ABSTRACT An experiment was conducted in a greenhouse at the Federal University of Lavras cultivated with American lettuce, cv. Raider-Plus. The aim of this study was to evaluate the effects of irrigation water depths applied by drip pulses and of soil coverage on crop yields and efficiency of water use. The experimental design used was randomized blocks with eight treatments and three replications, totaling twenty-four plots. The treatments consisted of soil with and without coverage (double-sided white and black plastic) associated with four irrigation management levels. Irrigation management consisted in reposition of irrigation depths based on crop evapotranspiration (ETc) with D1-100% of ETc, applied continuously (control), and D2 - 100% of ETc, D3 - 75% of ETc, and D4-50% of ETc, applied by pulses. Irrigation by pulses consisted in splitting the depths into six irrigation pulses with intervals of fifty minutes of rest. It was observed that pulse irrigation saved 25% of water in treatment without mulching and 50% when plastic mulching was used, contributing substantially to improve irrigation water efficiency.

ABSTRACT The objective of this study was to evaluate the concentration of cations in the leachate of soil cultivated with sugarcane irrigated with brackish water. An experiment was carried out in drainage lysimeters at the Federal Rural University of Pernambuco, at the Recife campus. The experimental design was completely randomized in a 5 x 2 factorial scheme, with four replicates, corresponding to five levels of electrical conductivity of the irrigation water (ECw) (0.5, 2.0, 3.5, 5.0 and 6.5 dS m-1) and two leaching fractions (LF1 = 0 and LF2 = 0.17) corresponding to water depths equivalent to 100 and 120% of crop evapotranspiration (ETc), by which the irrigations were managed. Electrical conductivity of the drained water was daily monitored and Na, K, Ca and Mg concentrations in the drainage water were determined at 129, 214, 286 and 324 days after planting (DAP). There were higher salt concentrations in the leachates when leaching fraction LF1 = 0 was used. The use of the 0.17 leaching fraction led to greater dissolution of the salts and may have caused a higher uptake of the essential cations by the crop. Sodium was the most quantitatively leached cation at all collection dates.

The rose is a major ornamental species produced in Brazil. Its propagation is mainly made by cutting. In the process, cutting and substrate can influence the quality of seedlings. Given the above, the aim of the present study was to evaluate the best cutting withdrawal region and the appropriate substrate for vegetative propagation of pot rose cv. Yellow Terrazza®. The experimental design was completely randomized in a 2x3 factorial [two cutting removal of regions, apical and median x three substrates: commercial substrate, clay soil and commercial substrate mixture (1:1, v/v) and sand and commercial substrate mixture (1:1, v/v)], with ten replicates. The experiment was conducted in a tunnel covered with shadecloth.The cuttings were placed in polypropylene vase with 100 cm³ capacity, filled with each substrate. Were evaluated the length of roots, number of roots/cutting and dry matter of roots and shoots. The apical cutting propagates with higher quality seedlings of pot rose cv. Yellow Terrazza® than the median cutting, without influence of substrate type. Got better preparation of the pot rose cutting with clay soil and commercial substrate mixture.
