“…In field studies, with increasing doses from 0 to 120; 80 and 120 kg ha −1 N, P and K, respectively, were not observed influences, for the number of panicles, in Tocantins, with application rates N ( Chan, 2016 ), plant population, with application of P ( Novais and Silva, 2016 ) and weight of 1000 grains, with K application ( Silva et al., 2018 ), in Paraná, corroborating the results found. The doses used in the experiments of these authors and the present study did not increase seedling emergence or made the area unfavorable for chia vegetative and reproductive development ( Novais and Silva, 2016 ).…”

“…It is noteworthy that, in previous studies, in the same place, the average yield found was 1,115 kg ha −1 ( Silva et al., 2018 ), demonstrating that, even with little difference between the means of the studies, it is possible to observe the influence of increased fertilization in chia grain production.…”

“… Silva et al. (2018) , when evaluating the residual effect of mineral fertilization at the doses of 300, 600, 900 and 1,200 kg ha −1 , observed that this effect remained until the end of the experiment, due to the amount of fertilization applied at the beginning and the permanence of the fertilizers nutrients in the soil at the end of the experiment.…”

Chia seed is expanding on the market due to its characteristics, but there are few studies on its response to residual fertilization of other crops. The objective was to evaluate the vegetative and productive parameters of common bean as a function of the base fertilization increment and to verify the influence of the residue of this fertilization on the development of chia. The experiment was carried out in two stages, Maringá State University, Umuarama Regional Campus, in a randomized block design with 4 replications. The treatments for the first stage were: T1 - doses recommended for beans and T2, T3, T4 and T5, were recommended doses for beans with increments for each treatment. The evaluated variables were: shoot dry matter, number of pods per plant, grains per plant, grains per pod, 1000 grains weight and yield. In the second stage, the experiment was installed in the same place of the previous cultivation. The treatments were: residual bean fertilization, T6 - plus the treatment with the recommendation for chia. The evaluated variables were: macro and micronutrient leaf contents, shoot dry matter, final plant population, 1.000 grains weight, oil content and yield. For beans and chia, soil samples were collected after harvest to evaluate chemical attributes. In common bean, the results were not significant in the evaluated parameters. In soil, the residual effect of beans was significant for P and K, with 27.2 mg dm −3 and 167.70 mg dm −3 , in treatment T5 and chia was 23.1 mg dm −3 and 89.7 mg dm −3 , for treatment T6, respectively. In chia, yield, oil content and P for leaf macro and micronutrient leaf contents were significant. Thus, the vegetative and productive parameters of the common bean were not influenced by the increase in fertilization. The residual effect was higher for P and K, for beans and chia. For chia, influences by residual effect were observed.

“…When compared the concentrations of each nutrient in the applied treatments (Table 1), it is noted that the two treatments (Claudio Roberto and Hoagland and Arnon) that presented higher values have a higher nitrogen content compared to the other formulations studied. Silva et al (2018), studying the effect of nitrogen and potassium doses on the production of broccoli seedlings, observed higher values of plant height, stem diameter, and shoot dry matter when applied the highest dose of N (240 mg.L -1 ). Cardoso et al (2017) reported a linear increase in the vegetative traits of Chinese cabbage (Brassica pekinensis) seedlings, the higher the applied nitrogen dose.…”

One of the main stages in the production system of a crop is the production of quality seedlings since it influences the plants' final performance in the field and their production. The study aimed to evaluate different nutrient solutions in the production of Cambuci pepper seedlings. The design used was a complete randomized design, with six treatments corresponding to the nutrient solutions proposed for the pepper crop by Castellane and Araújo, Claudio Roberto, Hoagland, and Arnon, besides the commercial products Plenan® and Biobokashi®, and a control treatment without fertilization, with six replications. The final evaluation was carried out 45 days after sowing. The following variables were analyzed: stem diameter, plant height, leaf dry matter, shoot dry matter, the number of leaves, relative chlorophyll index ("Spad"), and Dickson quality index. The seedlings subjected to the applications of Claudio Roberto and Hoagland and Arnon solutions have the highest heights and number of leaves, the largest stem diameter, shoot dry matter, leaf area, and Dickson quality index with 2.60 and 2.51 mm, 0.54 and 0.62 g, 38.64 and 41.91 cm2, and 0.107; 0.097, respectively. The Hoagland and Arnon nutrient solution provided the best characteristics to produce Cambuci pepper seedlings.

No-till broccoli production using different cover crop residues and nitrogen doses

et al. 2023

No-till vegetable farming is a feasible alternative to reduce erosion-induced losses and to increase soil nutrient availability, because cover crop residue protects the soil and its decomposition promotes nutrient cycling, which can improve the yield of the subsequent crop. The present study assessed the production and decomposition of cover crops and the agronomic performance of broccoli grown on this residue using different nitrogen doses in a no-till system. A randomized block design was used, in a split-split plot arrangement of main plots (cover crops), sub-plots (N doses) and sub-sub plots (decomposition times), with four repetitions. Seven cover crops were studied, as follows: [1) signal grass (SG); 2) sunn hemp (SH); 3) pearl millet (PM): 4) SG+SH; 5) SG+PM; 6) SH+PM and 7) SG+SH+PM]; in addition to four doses of nitrogen topdressing [T1) no N application (control); T2) 60 kg/ha N; T3) 90 kg/ha N and T4) 120 kg/ha N]; and five cover crop residue decomposition times: zero (cutting), 15, 30, 60 and 90 days after transplanting (DAT) the broccoli seedlings. Cover crop dry weight (DW) production, residue decomposition, and the head fresh (HFW) and dry weight (HDW) and yield (YLD) of broccoli were assessed. Among the cover crops, sunn hemp and the intercropped SG+SH treatment exhibited the lowest DW production and, along with signal grass, the shortest half-life (T½) and highest residue decomposition rate. The best-performing broccoli plants were those grown using PM, SH and a combination of both as cover crops. The highest broccoli production was obtained using sunn hemp residue, regardless of nitrogen topdressing, with HFW of 788 g/plant and YLD of 30 t/ha.
