Development, yield and quality attributes of sugarcane cultivars fertigated by subsurface drip irrigation

Abstract

The present study aimed to evaluate the development, yield and quality of four sugarcane cultivars fertigated by subsurface drip system. The experiment was carried out in Campinas-SP, Brazil, from January 2012 to November 2013, with the cultivars SP79-1011, IACSP94-2101, IACSP94-2094 and IACSP95-5000 subjected to daily irrigations. The irrigations depths were applied to bring soil moisture to field capacity. Soil moisture was monitored using soil moisture probes. Samples were collected along the crop cycle in order to evaluate crop development and yield, at the end of the first and second ratoons. Stalk height showed good correlation for the estimation of crop yield, with R2 equal to or higher than 0.96. The cultivar IACSP95-5000 showed the highest yield in the first ratoon. In the second ratoon the highest yield was observed in IACSP94-2101, followed by IACSP95-5000 and SP79-1011. Considering the yield results associated with the technological analysis, such as soluble solids content and apparent sucrose, the cultivar IACSP95-5000 excelled the others in the cultivation under subsurface drip irrigation.

Physiological and biochemical processes underlying the differential sucrose yield and biomass production in sugarcane varieties

“…A field experiment was carried out with the sugarcane ( Saccharum spp.) varieties IACSP95-5000 and IACSP94-2094, two commercial varieties with differential biomass production and yield (Silva et al., 2016). IACSP95-5000 presents high yield in non-restrictive environments (Cruz et al., 2021), while IACSP94-2094 is considered rustic and drought-resistant and indicated for less favourable environments (Sales et al., 2013).…”

“…Dynamic losses are not considered. As a limitation of our analysis, this means that we do not consider the effect of the frequency of loading and unloading cycles on the (Turchi et al, 2019) 58 (De Vita et al, 2018 126 (ESTELA et al, 2015) 51 Medium Cost 60 (De Vita et al, 2018) 103 (ESTELA et al, 2015) 48 Low Cost 45 (De Vita et al, 2018) 80 (ESTELA et al, 2015 46…”

Adaptation and Responsiveness of Sugarcane Cultivars Under Irrigated and Rainfed Production Systems

“…Combinations of sugarcane cultivars without water restriction and with water restriction in their respective cultivation cycles should be studied to ensure farmers high yield levels and maintain the economic sustainability of the system. In this context, Silva et al (2016) stated that some cultivars have greater productive potential when under irrigated conditions. Leal et al (2017) reinforced the need for studies combining different sugarcane genotypes in varied production environments and crop cycles.…”
