Advantages of Inter-Especific Hybrid Cotton Varieties in the Mediterranean Area

The research conducted by Manuel Lopez Garcia, Felipe Rey Montero, and Khaled Shalabi focuses on studying different cotton varieties in Spain through pivot irrigation systems to determine the species best suited for the Mediterranean climate. The study, initiated in 2014, compared fertigation systems and concluded that hybrid varieties outperformed hirsutum and barbadense species, with pivot irrigation showing higher efficiency. The trials in Los Palacios monitored temperature, precipitation, and fiber production, emphasizing the importance of interspecific hybrid varieties for optimal adaptation.

1. ADVANTAGES OF INTER-ESPECIFIC HYBRID COTTON VARIETIES IN THE MEDITERRANEAN AREA BY PIVOT IRRIGATIONS Manuel Lopez Garcia (Research Center IFAPA Centro Las Torres SPAIN) Felipe Rey Montero (Research Manager Semillas Sostenibles Iberica SPAIN) Khaled Shalabi (Agricultural Research Engineering Institute- ARC-Giza, EGYPT)

2. Objectives of the study The main objective of this research is the study of the behavior of the different varieties planted in Spain through fertirrigations system through pivot in order to observe which species are better adapted to our growing needs This study started in 2014 and was presented by the same authors in Sharm El Sheikh October 2015. The study presented in 2015 compared the two most efficient fertirrigation systems LEPA irrigation (Low energy applications precision) and its impact on the varieties studied in both performance (kg / ha) and fiber characteristics (HVI system). The conclusions of the trial demonstrated the supremacy of the hybrid varieties against the hirsutum and barbadense, and regarding the irrigation system, the pivot system demonstrated greater efficiency.

3. Introduction Spain cotton area has "Mediterranean climate", the temperature varies widely during the growing season (April-October), variations between 15 C to 43 C. are normal

6. Introduction ELS fiber production began in Spain in 2007 and in 2016 reached 5.500 hectares with an average yield of fiber of 1.600 kg / has The ELS varieties used by producers are only interspecific hybrid varieties, are the only ones able to adapt to our GD-15,5C GD-15,5C has a range between 1.150 GD/1.350 GD Manuel Lopez Garcia

7. The graphics show 1.285 DG-15,5C (from planting to harvest )

8. Material and methods The field was located in Seville (Spain SW 37 4'N) The soil type is called "Vertisol" (deep, fertile soil and its physical composition is clay loam)

9. Material and methods The trial consists in thirteen varieties with four replications (split plot). The elemental plot was 4 row 10 meters long with a separation between row 0.75 meters. The distance between repetitions was two meters. The planting was effected on April 28, resulting population density was 100.000 plants/Ha
