“…The decrease in PP after the 247.95 mm irrigation level probably resulted from nutrient leaching to deeper soil layers. In non-excessively acidic sandy soils with low cation exchange capacity and low water retention capacity, as is the case of the Neosol used in this study (Table 1), the use of high irrigation depths favors the leaching of nutrients from the root region of the crop (Campelo et al, 2014;Nowaki et al, 2017).…”

“…By evaluating the effects of conventional N fertilization on watermelon cultivation, Araújo et al (2011), Barros et al (2012), and Nowaki et al (2017) found that the maximum yield of watermelon was obtained with applications of 144.70, 114.76, and 187 kg ha-1 of N, Pereira et al (2020) Phytotechnical parameters and yield of... respectively. However, Morais et al (2008) found that the highest fruit yield was obtained with 421 mm of water and 267 kg ha-1 of N applied in a conventional way.…”

Water and nitrogen availability are fundamental for obtaining a high yield of the watermelon plant. However, the appropriate levels of irrigation and nitrogen to be applied according to specific cultivation conditions should be previously determined. The objective of the present study was to evaluate the effects of irrigation and nitrogen levels in fertigation on the phytotechnical parameters and yield of the Top Gun hybrid watermelon plant. The experiment was conducted at São Luiz Ranch, in Bom Jesus (PI), from August 4 to October 15, 2015. The blocks in strips experimental design was used with four repetitions, and the treatments consisted of five irrigation depths (114.17, 156.86, 221.16, 268.87, and 317.09 mm) and five doses of nitrogen in fertigation (0, 50, 100, 150, and 200 kg ha-1). The growth rate of the main and primary branches, leaf area, specific leaf area, stem diameter, dry mass of the aerial part, number of fruits, and commercial production per plant were evaluated. Both hydric and nutritional stress caused decreased growth rates, leaf areas, and specific leaf areas, and the highest growth expressions were found with the combination of a 317.09 mm irrigation depth and 200 kg ha-1 nitrogen. The irrigation depths did not influence the diameter of the stem nor the accumulation of dry mass. Nitrogen doses did not influence the number of fruits and production. The 247.95 mm irrigation depth promoted the highest commercial fruit production of the watermelon plant.

“…The treatment of P3 results in significant effect compared to the control, respectively 64, 25 cm and 4.05 kg fruit -1 , while for control, it is respectively 53.96 cm and 2.80. kg fruit -1 Nitrogen given in the form of fertilizer up to 120 kg (N ha -1 ) can accelerate flowering process from 33.4 to 28.13 days, and increase the weight of fruit from 1.53 to 2.92 kg each . The use of N fertilizer of 200 kg/ha can also increase the production of watermelon up to 40 ton ha -1 in Brazilian Jaboticabal (Nowaki, Filho, De Faria, & Cortez, 2017). The use of N in the form of organic fertilizer that comes from manure and inorganic N in the form of Calcium Ammonium Nitrate can increase marketable watermelon yield (Audi, Aguyoh, & Gao-Qiong, 2013).…”

The difficulty of seeding and sweetness quality of seedless watermelon is an obstacle for farmers. The objectives of this study were to know the successful of shoots growth with seeding treatment and production quality due to fertilizing package for seedless watermelon with the variety of Riendow F1. The experiment was conducted in dry season at upland areas in Palangkaraya. The experimental design for seeding randomized block design (RBD) 3x3 with treatment consisting of a control (G0), cracking seed by hitting (G1), cracking seed using pincette (G2). The experiment of fertilizing package at productive phase used of fertilizer used RBD 4x3. The treatment consisted of several packages of fertilizer, namely: without fertilization (P0), low fertilizer package (P1), medium fertilizer package (P2), and high fertilizer package (P3). Before the experiment, soil analysis was first conducted to determine land suitability classes. The results showed that the study site area has marginal suitability class with limiting factor involving rooting condition (S3rc). The highest germination was obtained in the cracking treatment compared to control, otherwise, the rate of death seeds for control was lower than cracking treatment although it is not significantly different according to statistics. For the parameter of fruit perimeter, it indicates that treatment of high fertilizing package was significantly different from the control, respectively, 64.25 cm and 53.96 cm. It also includes the weight of fruit, respectively, 4.05 kg and 2.80 kg. For the quality of watermelon, it showed that fertilizing packages at productive phase is significantly different from controls. The sweetness level at the medium fertilizing package (P2) has the highest level of 11.73 o Brix, followed by the high fertilizing package (P3), 11.00 o Brix, low fertilizing package (P1), 9.92 o Brix and the lowest for control, 8.98 o Brix. Application of medium fertilizing package at productive phase can then produce the highest quality level of watermelon.

“…In soil cultivation, a widely evaluated and recommended method for regular collection of soil solution, also used for monitoring the fertility levels, is the use of porous ceramic cup extractors (OLIVEIRA et al, 2011;JIMÉNEZ;PLAZA;LAO, 2012;OLIVEIRA et al, 2013;SOUZA et al, 2013;OLIVEIRA et al, 2015;NOWAKI et al, 2017). More recently, this method has been used for cultivation systems in substrates in order to monitor the electrical conductivity (WRIGHT et al, 2009).…”

The aim of this study was to evaluate the efficiency of the porous ceramic cup extractors, associated with ion meters, for the determination of nutrients availability for bell pepper and melon crops in substrate. Substrate solution was acquired using aqueous extract 1:1.5 (v/v) and also the porous ceramic cup extractor. Electrical conductivity (EC), pH and macronutrient contents were determined for the substrate solution through analytical method. The concentrations of NO- and K+ in the solutions obtained with porous ceramic cup extractors, and the N and K contents in the diagnostic leaf for nutritional evaluation were also determined. The concentrations of NO3- and K+ using the porous ceramic cup extractors have strong correlation (r=0.96 and 0.92, respectively) with the ones obtained using the standard method, as well as a moderate correlation (r=0.65) and a strong one (r=0.71) with contents of N and K, respectively, in the melon diagnostic leaf; and a weak correlation (r=0.36 and 0.26, respectively) in the bell pepper diagnostic leaf. The use of porous ceramic cup extractors for obtaining the substrate solution and the determination of the N-NO- and K+ contents by means of specific ion meters are a fast method of evaluating nutrients availability in soilless cultures.
