“…In addition, the positive and statistically significant correlation between capitulum growth and grain yield (r = 0.94**) must be pointed out. Plant height results corroborate those obtained by Costa et al (2009), who observed residual effect of sewage sludge on the height of maize plants for the application of 75 and 150 kg ha -1 . On the other hand, these authors did not observe significant increments in stem diameter, despite using sewage sludge doses higher than those tested in this study.…”

This study aimed to evaluate the residual effect of sewage sludge fertilization on yield and nutrition of sunflower in its second cycle. The experiment was carried out from April to August 2012. The treatments consisted of four doses of sewage sludge (0, 10, 20 and 30 t ha-1, dry basis) applied in the first cycle of sunflower, distributed in a randomized block design, with six replicates. Sunflower stem diameter, plant height, capitulum diameter and yield increased with the increment in sewage sludge doses, with maximum values observed with the dose of 30 t ha-1. The contents of calcium and magnesium in the soil, pH, sum of bases, effective and potential cation exchange capacity and base saturation increased, while potential acidity and the contents of manganese and iron in the leaves decreased, with the increment in the residual doses of sewage sludge. There was a reduction in yield and growth characteristics of sunflower in the second cycle; thus, additional fertilization with sewage sludge is recommended in each new cycle.

“…The wastewater had in all evaluations higher values when compared to the water supply. Costa et al (2009) confirmed it on studying the stem diameter of the corn stalk. SD was higher for plants receiving wastewater compared to the results of plants that received water supply.…”

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.

“…Em plantas de milho, Costa et al (2009) Com relação à variável fitomassa seca de raiz, houve efeito significativo (p<0,01) do fator dose de esterco apenas aos 37 e 44 DAS, não sendo verificado efeito (p>0,01) do fator tipo de água e nem da interação tipo de água x dose de esterco para nenhuma data de estudo. As médias de fitomassa seca da raiz produzida aos 23 e 30 DAS foram de 3,28 e 3,65 g, respectivamente.…”
