“…The average achene yields obtained with the drip irrigation system for cultivars Hélio 251 and Hélio 360 corroborate those reported by Simões et al (2016), who evaluated the influence of different irrigation amounts and dripper arrangements on the morphophysiological traits of sunflower cultivars and obtained yields between 2,500 and 5,000 kg ha -1 in cultivar Hélio 251 and between 4,000 and 5,000 kg ha -1 in Hélio 360. Some studies have shown that the increase in sunflower production provided by irrigation varies from 30 to 100%, with values greater than 70% in semiarid regions (Anastasi et al, 2010;Flagella et al, 2002;Goksoy et al, 2004;M.…”

“…Water requirements can be met with around 200 mm to more than 900 mm per crop cycle. When well-distributed throughout the cycle, water volumes of 400 to 500 mm result in high grain, oil and dry matter yields, demonstrating the feasibility of implementing irrigation systems (E. P. Gomes et al, 2012;Simões et al, 2016Simões et al, , 2018.…”

“…When irrigated, the sunflower crop has a grain yield generally between 2,200 to 3,000 kg ha -1 (Biscaro et al, 2008;Flagella, Rotunno, Tarantino, Di Caterina, & De Caro, 2002;Silva, Faria, Morais, Andrade, & Lima, 2007;Simões, Drumond, Oliveira, Gonçalves, & Guimarães, 2018;Smiderle, Mourão, Jr., & Gianluppi, 2005). However, there are records of grain yields exceeding 6,300 kg ha -1 under irrigation (Anastasi, Santonoceto, Giuffre, Sortino, & Abbate, 2010;Goksoy, Demir, Turan, & Dagustu, 2004; E. P. Gomes et al, 2012;Karam et al, 2007;Simões et al, 2016).…”

The growth and yield of sunflower plants can be influenced by the plant population arrangement and the type of irrigation system adopted to meet the water requirements of the crop. This study examines the influence of different irrigation systems and spacings between planting rows on the development of sunflower cultivars for the sub-middle region of São Francisco Valley. The experiment was laid out in a randomized block design with a split-plot arrangement in which the plots consisted of three irrigation systems (drip, micro-sprinkler and sprinkler); sub-plots were represented by three spacings between planting rows (0.65, 0.55 and 0.45 m); and sub-sub-plots corresponded to two sunflower cultivars (Hélio 251 and Hélio 360). The following variables were analyzed: plant height; number of leaves; stem diameter; number of heads; head diameter; dry biomass of stems, leaves and heads; and achene yield. The different irrigation systems and row spacings markedly influenced the growth of the sunflower cultivars. The highest yield of cultivar Hélio 251 was obtained with the drip irrigation system and 0.55 m spacing. Cultivar Hélio 360 achieved the highest yields when irrigated by the micro-sprinkler system at 0.55 and 0.45 m spacing. In the sprinkler irrigation system, cultivar Hélio 360 obtained the highest yield at 0.45 m spacing.

“…Evaluations of irrigation water depths have been used to determine water requirements of crops under specific growing conditions (SIMÕES et al, 2016). Low water availability reduces plant production, and excess water limits soil aeration, affects absorption of nutrients, increases disease risks, and contributes to nutrient leaching (VIANA et al, 2012).…”

Goat Manure Fertilization and Irrigation on Production Components of Sunflower

et al. 2019

Sunflower can be an economically viable crop in the Northeast region of Brazil depending on the use of appropriate irrigation and fertilization managements. The objective of this work was to evaluate production components of sunflower plants (Helianthus annuus L.) of the BRS-324 cultivar subjected to different organic fertilizer rates (goat manure) and irrigation water depths in two crop cycles (November 2014 to February 2015; and August to November 2015). The experiment was conducted in a randomized block design with a split-split-plot arrangement, consisting of five organic fertilizer rates (OFR) (0, 300, 600, 900, and 1.200 mL plant-1 week-1) and five irrigation water depths (IWD) (33; 66; 100; 133, and 166% of the class A tank evaporation), with three blocks. The highest achene yield (1,220.78 kg ha-1) in the first cycle was found using OFR of 1,200 mL plant-1 week-1 and IWD of 134.9% (524.9 mm); and the highest yield (882.07 kg ha-1) in the second crop cycle was found using the highest OFR combined with IWD of 166% (843.0 mm). The use of goat manure as organic fertilizer had no effect on the sunflower oil content; however, this variable was affected by the irrigation water depths used. Protein content was higher in the second crop cycle (14%) when using IWD of 100% and OFR of 536 mL plant-1 week-1.

The objective of this work was to evaluate the production costs and profitability indexes of sorghum crop for silage production under different irrigation depths. The work was conducted at the Federal Institute of Education, Science and Technology of Ceará (IFCE) – Umirim Campus, from September to December 2016. The treatments were arranged in 5 x 5 split plots with 5 replications. Irrigations were performed on a daily basis, and the applied depths were calculated based on crop evapotranspiration (ETc). The primary treatments were 50, 75, 100, 125 and 150% of ETc, associated with different levels of carnauba bagana mulch (0.00, 2.50, 3.75, 5.00, and 6.25 cm). Effective Operating Cost (EOC), Total Operating Cost (TOC), Gross Revenue (GR), Operating Profit (OP), Profitability Index (PI) and Break-Even Price (BEP) were estimated. According to the indicators analyzed, it was found that this is a promising crop within the different agricultural production schools, with favorable rates for the producer. The variety evaluated presents high resistance as to the water limitation factor, showing positive indicators such as break-even point below the average prices practiced in the region.
