“…Added to these is its higher cost when compared with the other fertilization methods, which use traditional fertilizers mixed with substrate or fertigation. Given that complete fertigation solutions with electrical conductivity between 1.5 and 2.0 dS m −1 have been used in plant (Ludwig and Fernandes 2013) and seedling production in substrate (Coelho et al 2018), a solution of 2.0 dS m −1 was studied.…”

The aim of this study was to assess the agronomic performance and costs of slow release fertilizers and fertigation in the production of sugarcane and passion fruit seedlings in tubes. Two experiments were carried out simultaneously, one with sugarcane seedlings (SP80-3280) obtained from stalks with one bud (4 cm) and the other with passion fruit (FB-300) from seeds. Both experiments were conducted in 200-cm 3 tubes filled with composted pine bark-based substrate, with six treatments: (1) control; (2) standard fertilization (g 100 L −1 of substrate), (NH 4) 2 SO 4 (300) + KCl (200) + magnesium thermophosphate (200) + Osmocote® 15-9-12 Plus (600) + Osmocote® 19-6-10 Mini-Prill (600); (3) Osmocote® 15-9-12 Plus (600 g 100 L −1 of substrate); (4) Osmocote® 19-6-10 Mini-Prill (600 g 100 L −1 of substrate); (5) complete fertigation (g 100 L −1 of water), Ca(NO 3) 2 (80) + KNO 3 (50) + MgSO4 (35) + (NH 4) 3 PO4 (10) + ConMicros® Standard (2.5); and (6) macronutrient fertigation, equal 5. except ConMicros®. The results were as follows: (1) sugarcane (70 days) and passion fruit (52 days) seedlings were larger in the fertilized than control tubes; (2) standard fertilization, Osmocote® Mini-Prill, or Osmocote® Plus produced sugarcane and passion fruit seedlings with greater mass; (3) fertigations were the most inexpensive fertilizations; and (4) the slow release fertilizer Osmocote® 19-6-10 Mini-Prill presented larger seedlings, but it cost more (2-3 times) than fertigation. Substrate fertilization is essential for sugarcane and passion fruit seedlings' production in tubes because the substrate itself is not able to provide enough nutrients for seedling development, and although standard fertilization and slow release fertilizers (Osmocote®) allow to produce larger seedlings, they are more expensive than fertigation.

“…Considering eight growth variables, the best C. arabica cv. Topázio seedling development occurs with complete nutrient solutions between 1.4 and 2.2 dS m -1 (Coelho et al, 2018).…”

“…Seeds were obtained from a Topázio cultivar coffee (C. arabica, originated from Catuaí amarelo and Mundo Novo, small size, medium fruit maturation and high productivity) crop in Uberaba, Minas Gerais (MG), Brazil, in May 2016. The seeds were extracted from fruits and germinated according Meireles et al (2007) and adapted by Coelho et al (2018). Seedlings with a 4 mm radicle were selected and planted in plastic cone-shaped containers (120 x 30 mm and volume of 50 cm 3 ), filled with composted pine bark-based substrate (Bioplant ® , minor components: sphagnum moss, coconut fiber, carbonized rice husk; properties: pH=6.5, EC=0.8 mS cm -1 , maximum water retention=100%).…”

“…However, nutrient release can vary over time and depends on uncontrollable factors such as temperature (Adams;Frantz;Bugbee, 2013). Fertigation makes possible to manage seedling nutrition throughout its development, thereby reducing heterogeneous availability and leaching losses (Coelho et al, 2018). Moreover, fertigation is cheaper than slow-release fertilizers (Silva et al, 2020).…”

Coffee seedling production in cone-shaped containers and substrate results in lower sanitary risk and costs. With the use of small containers and substrates with low fertilizer levels, fertigation is necessary for seedling development. An experiment was carried out with three macronutrient concentrations (electrical conductivities of 1.0, 2.0 and 3.0 dS m -1 ) and a non-fertilized control using Coffea arabica cv. Topázio seedlings in 50 cm 3 cone-shaped containers and composted pine bark-based substrate. The following fertilizers (expressed in g m -3 of water) were used in the nutrient solution with EC of 1.0 dS m -1 : Ca(NO 3 ) 2 (400), KNO 3 (250), MgSO 4 (175), (NH 4 )PO 4 (50) and ConMicros Standard ® (25). In the solutions with 2.0 and 3.0 dS m -1 , macronutrient concentration was doubled and tripled, while micronutrients remained the same. At four months we assessed EC and pH of the solution drained, shoot dry mass, shoot nutrient concentration and accumulation and macronutrient use efficiency. Fertigation with 1.0 and 2.0 dS m -1 produced seedlings with greater mass (+10%) than fertigation with 3.0 dS m -1 , while higher macronutrient supplies increased shoot N, P, K, Mg and S concentration. Fertigation with 2.0 dS m -1 caused greater shoot N, P, K and Ca accumulation and this conductivity also resulted in higher accumulation of B, Fe, Mn and Zn without increasing the micronutrient supply. The response to the increase in Ca in the nutrient solution is evident in the accumulation of this nutrient in the plant but not its concentration, possibly due to the dilution effect. Micronutrient accumulation in this species is also more adequate for determining nutritional status than the concentration in the plant. The least concentrated macronutrient solution increases nutrient use efficiency in C. arabica seedlings as well as being economically and environmentally more sustainable.

“…Thus, fertigation enables the controlled application of nutrients adjusted to the phenological stages (COELHO et al, 2018) and, despite favoring the achievement of high yields in irrigated crops, if poorly managed, it can considerably increase the concentration of salts in the soil that, when exceeding plant tolerance limits, negatively affects crop growth and productivity (SILVA et al, 2013).…”

Fertirrigation allows total control of the amount of applied fertilizers to the soil as a function of crop demand. Fertigation relies on monitoring of soil ions to obtain the sustainability of soil chemical conditions. The continuous evaluation of ions in the soil solution also contributes to the estimation of the cycling rate of chemical elements and nutrient leaching in the field. The objective of this work was (i) to evaluate nitrate, potassium, sodium and electrical conductivity in the soil solution submitted to different concentrations of injection solution and fertigation frequency during one cycle of the "Grande Naine" banana in a non-cohesive Yellow Latosol and (ii) to evaluate the effects of concentration and fertigation frequency on yields of banana crop. The experiment was carried out according to a randomized block design with six treatments and four replications in a 3 x 2 factorial scheme with three concentrations of the injection solution (3, 10 and 15 g L-1) x two fertigation frequencies (3 and 7 days). The treatments influenced the values of the ion concentration in the soil solution in the soil profile corresponding to the depths of 0-0.30 e 0.30-0.60 m. The concentration of the injection solution and the interaction frequency x concentration influenced the electrical conductivity and nitrate concentration of the soil solution. There was no significant effect of the injection solution and fertigation frequency on production variables.
