Abstract

HIGHLIGHTS The number of flowers, the abortion rate, and the number of fruits per flower cluster directly influence processing tomato yield. Deficient or excessive irrigation levels impair flowering and increase the abortion of flowers of the processing tomato. Irrigation management is essential for the yield of processing tomato crops from the Brazilian Cerrado.

Highlights

Water deficiency is one factor that limits gains in yield and quality of the raw material in the tomato industry, excess water can be harmful (Nangare et al, 2016; Ganeva et al, 2019; Ragab et al, 2019)
This research aimed to evaluate the effect of irrigation depths on flowering, fruiting, flower abortion and the influence of these variables on tomato yield for industrial processing (BRS Sena hybrid), subsurface drip-irrigated in Cerrado areas from the Southern Goiás, Brazil
In the first year of research, no typical symptoms of infection by Begomovirus species were found in the crop

Summary

Introduction

Water deficiency is one factor that limits gains in yield and quality of the raw material in the tomato industry, excess water can be harmful (Nangare et al, 2016; Ganeva et al, 2019; Ragab et al, 2019). The water deficit increases the flower abortion rate and reduces the fruit mass, directly interfering in yield (Silva et al, 2013; Nangare et al, 2016; Sivakumar & Srividhya, 2016; Ganeva et al, 2018; 2019; Giuliani et al, 2018). According to Ganeva et al (2018; 2019), the combination of water deficit and high temperatures negatively impacts industrial tomato flowering and fruit formation. These negative impacts depending on the edaphoclimatic conditions and the tomato hybrid (Bacallao & Fundora, 2014). It is evident that the water replacement in the soil by irrigation, in quantity and at the right time, is decisive for crop success (Hott et al, 2018; Ragab et al, 2019)
