“…The fertigation method is another technique that allows the application of fertilizers. This technique enables the application of nutrients mixed with the irrigation water, ensuring uniform distribution of nutrients on the area, labor saving and high efficiency of nutrients utilization, allowing also the fertilizer to be applied in the region with higher concentration of roots, besides better fractionation of doses [2]. The use of fertilizers in liquid form via foliar spraying or fertigation is increasing in agriculture.…”

Fertilization is an important and limiting factor for growth and tuber production of potatoes crop because plants non adsorption amounts of nutrients from the soil. Data obtained the tea compost spray or tea compost fertigation single or mixed with mineral-N. Resulted in grand mean the highest tuber yield of potatoes tea compost methods, the value of tuber yield value (42.34 tan ha -1) which relatively increased by about 15.68%, 11.31% over the untreated addition compost to soil and tea compost fertigation.Also data show that grand mean the highest shoot dry weight of potatoes foliar compost tea methods, the value of tuber yield value (4.79 tan ha -1) which relatively increased by about 41.54%,24.43% over the untreated addition compost to soil and tea compost fertigation. Also data show under methods, fertigaion compost tea, with treatment 50% compost tea+ 50% mineral –N seems to be the best ones in nitrogen uptake by tuber potato plant (131.24 kg ha-1). the compost tea fertigation, % Ndff, Ndfcompost in tuber was much higher for tea compost fertigation (57.74 kg ha-1) ,(56.62 kg ha -1 )than for compost tea foliar methods (50.21 kg ha-1),(51.84 kg ha-1) and compost addition to soil (33.02 kg ha-1) , (27.82 kg ha-1) respectively . The percentage nitrogen use efficiency (%NUE) by tuber ranged from %9.17 to %16.27 due to (MA1)+R2 and 100 % MF , respectively.

“…The efficiency of drip irrigation has been studied by several researchers in different crops, such as Lactuca sativa (Brunin et al 2019); Solanum lycopersicum L. (Silva et al 2019); Brassica oleracea var. botrytis (Pereira et al 2018); Cichorium intybus (Biscaro et al 2012); Ricinus communis L. (Souza et al 2005). The high uniformity of drip irrigation Brazilian Journal of Development, Curitiba, v.7, n.1, p. 9459-9473 Jan. 2021 system, close to 90%, provides greater fertirrigation efficiency and is currently considered one of the most important productivity factors for agriculture.…”

The search for maximizing crop productivity involves new technological procedures, in which fertirrigation makes great potential, due to the importance of defining the best way of applying water and nutrients (in this case nitrogen) to crops express their maximum productive potential. The objective of this work was to evaluate irrigated carrot culture by surface and subsurface drip irrigation with different nitrogen doses applied in fertirrigation. The experimental design was randomized blocks in factorial scheme 2 x 6 (type of grip irrigation x Nitrogen doses), with four replicates. The types of drip irrigation used were surface and subsurface and Nitrogen doses were zero, 30, 60, 90, 120 and 150 kg ha -1 . Fertirrigations were divided into three applications at 30, 50 and 70 days after emergence. The carrot harvest was performed at 90 days of cultivation, when root, shoot and total length were evaluated, as well as root and upper root diameters and estimated yield. It was observed that carrot cultivation is influenced by irrigation system used and by Nitrogen rates, being the highest productivity when plants were submitted to 90.4 kg ha -1 of Nitrogen by subsurface drip irrigation.

The objective of this study was to evaluate, in greenhouse, the response of the lettuce cultivar 'Vera', with respect to the marketable shoot dry matter production and macronutrient accumulation, as a function of the application of different doses of nitrogen (N) and a potassium silicate-based leaf fertilizer. The lettuce was cultivated from August 10, 2012 (sowing) to October 16, 2012 (harvest). The experimental design was completely randomized with three replicates, referring to nine treatments, resulting from the combination between top-dressing doses of N (9, 54, 90, 126 and 171 kg ha-1) and Si/K2O (1.15, 6.90, 11.50, 16.10 and 21.85 kg ha-1), using the Plan Puebla III experimental matrix, and a control treatment without fertigation. Drip fertigation was used for the application of the doses. The highest doses of N and Si/K2O resulted in the highest marketable shoot dry matter production and highest leaf accumulation of magnesium, calcium, potassium and phosphorus.
