“…In research conducted with commercial substrate in the yield of seedlings of three black pepper genotypes, Serrano et al (2012) observed the number of leaves for an average of 11.1 (Gajarina), 11.0 (Iaçara) and 12.9 (Singapore). Corroborating with the results of these authors, the "Biquinho" pepper with bovine substrate produced an average of 15.4 leaves at 144 DAS, and with caprine substrate an average of 19.34 leaves at 170 DAS; indicating that organic substrates used propitiated conditions favorable to the crop.…”

The amount of water needed to meet the water requirement of crops and use of alternative organic substrates affect the development of the plants' nutrients. The objective of this research is to evaluate the cultivation of pepper (Capsicum chinense) under different organic substrates and irrigation levels with supply water and wastewater. The experiment was conducted in a greenhouse at Campina Grande, Paraíba, Brazil. Biquinho BRS Moema pepper species was used. The experimental design was randomized block in a factorial design of 2 x 5 x 2. Two types of water (water supply and wastewater) and five water levels (L) were used based on the water requirement (WR) of the crop as follows: 100% WR (L5), 80% WR (L4), 60% WR (L3), 40% WR (L2) and 20% WR (L1); and two kinds of substrates (caprine and bovine) were also used, all in three replicates with two plants each. The germination percentage for bovine substrate averaged 44%, while for the caprine substrate, it was 18%. 24% increase in the number of leaves at level 4 was compared with that of level 5, where there was 20% reduction of WR of the plant. The pepper "Biquinho" irrigated with wastewater had better average, making it an alternative for irrigation. For the growth of pepper, it is not suitable to use irrigation values less than 40% of the water requirement for culture, because it influences negatively the development of the culture. For pepper, the ideal irrigation level is 80% of water requirement.

“…piperis) and the southern root-knot nematode (Meloidogyne incognita), which have, in part, being disseminated through cutting. This technique of vegetative propagation is the more utilized, currently, with the species P. nigrum, with good success in function of the maintaining of the characteristics of the selected genetic materials, and some works confirm the efficacy of this method (Serrano et al, 2012;Secundino et al, 2014), where the quality of the root system, such as number, volume and root dry mass is fundamental in the survival and acceptability of the seedling in the field. of the CEUNES/UFES ( Table 1).…”

The soil in the production of clonal seedlings of black pepper (Piper nigrum L.) contributes to fusarium and nematodes infestation in commercial crops, and thus the usage of alternative substrates might be a preventive control measure against these pathogens. The aim of this study was to investigate the rhizogenic behavior of the cultivars Bragantina, Iaçará and Guajarina of black pepper in different substrates. The experimental design was in randomized blocks in a 3x4 factorial design (cultivars: Bragantina, Iaçará and Guajarina x substrates: soil + organic compound (18%), vermiculite, carbonized rice hulls and commercial substrate), with four replications of 16 cuttings each. The evaluated characteristics were: survival (%); rooting (basal or nodal) (%); nodal rooting (%); basal rooting (%); number of nodal roots; number of basal roots; total number of roots; length of the largest nodal root (cm); basal root length (cm); nodal root volume (cm3); basal root volume (cm3); Total root volume (cm3); nodal root dry mass (mg); basal root dry mass (mg) and the total root dry mass (mg). There are differences within black pepper cultivars as to the characteristics related to the root system. The vermiculite substrate was the most suitable, and carbonized rice hull is not recommended for the adventitious rooting of cuttings of cultivars Bragantina, Iaçará and Guajarina.

Angelonia integerrima is a native species that has ornamental potential, being cultivated in flowerbeds, flowerpots, pots, or even used as a complement in floral arrangements. Knowledge of mineral nutrition is required for the cultivation of the species, and slow release fertilization have become widespread in recent years, with a lower risk of toxicity to crops, an economy in relation to complementary fertilizers and may be an alternative to cultivation of potted plants. The aim of this study was to evaluate the development of Angelonia integerrima Sprengel in pot under slow release fertilization doses. Acclimatized seedlings with approximately 1 cm height, from in vitro germinated seeds were transplanted into 1 L pots containing substrate composted Pinus bark. Five doses of Basacote ® 9M slow release fertilizer, formulation 16-8-12 (N - P2O5 - K2O), 9 months: control - 0 g L-1, 2.5 g L-1, 5.0 g L-1, 7.5 g L-1 and 10.0 g L-1. The plants were grown in a greenhouse under drip irrigation. The shoot length, length of the largest inflorescence, number of stems, diameter of the largest stem, mean length of the stems, number of open flowers, fruits and senescent flowers, chlorophyll a, b and total, mass of dry matter of shoot and root system were evaluated after 286 days. The experimental design was completely randomized, with four replicates of six pots per plot. Data were submitted to analysis of variance (ANOVA) followed by polynomial regression by SigmaPlot 11.0. It was possible to adjust a quadratic equation for the variables: shoot length (with maximum response point in 7.2 g L-1), mean length of stems (6.7 g L-1), diameter of the largest stem and the root system (5.9 g L-1), number of open flowers, buds, senescent flowers and total flowers (7.7 g L-1). For the variables, number of stems, number of fruits, chlorophyll a, b and total did not differ between treatments. The slow releaser fertilizer indicated dose for the cultivation of the potted species is 7.2 g L-1.
