ABSTRACT
BACKGROUND:
The need to increase marketable tomato yields and decrease losses due to sunburn and disease during the summer motivates farmers to adopt additional cultural practices such as shading and grafting. To investigate complex interactions among grafting, shading, and tomato cultivar, grafted and ungrafted tomatoes (cv. 'Optima' F1 and cv. 'Big Beef' F1 ) were grown in the soil under net-house cover, using pearl and red nets, and in unshaded conditions (open fields). Tomato fruit at the red stage of maturity were used for the analysis of quality traits, and total and marketable yields were recorded during the whole production season.RESULTS:
Grafting and shading in tomato production might be considered as cultivation practices to increase the marketable tomato yield. A decrease in sugar content increased the uptake of some micro elements (Fe and Zn) and macro elements (Ca). In some cases, firmer and less elastic skin may be expected due to grafting. Shading with pearl net might result in fruit with lower firmness and higher total, and particularly malic, acid content.CONCLUSION:
Shading with colored nets and grafting provide alternative strategies for achieving higher fruit yields and avoiding or reducing a decrease in tomato quality caused by environmental stresses such as excessive radiation and temperature in the summer cropping season. © 2019 Society of Chemical Industry.Palabras clave
