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.

The use of organic residues in the formulation of substrates for the production of papaya seedlings may favor the physical, chemical, and biological properties of the soil, resulting in better quality seedlings. The objective of this work was to evaluate the effect of substrates formulated in ratios (residue:soil) with organic residues for the production of papaya (Carica papaya L.) seedlings. The experimental design was a randomized complete block design, in a 5 (residues) x 2 (ratios) factorial scheme with an additional treatment (control), with three replications and the plots constituted by 10 plants. The treatments were: T1 -soybean residue + soil (1:2

RESUMO O objetivo deste trabalho foi avaliar a produção de mudas de laranjeiras doces ‘Pera’ e ‘Westin’, tangerineira-tangor ‘Piemonte’ e limeira-ácida ‘Tahiti’ enxertadas em 14 porta-enxertos de citros em viveiro protegido. As mudas de laranjeiras-doces ‘Pera D-6’ e ‘Westin’, tangerineira-tangor ‘Piemonte’ e limeira-ácida ‘Tahiti CNPMF-02’ foram avaliadas em viveiro protegido após a enxertia, em 11 porta-enxertos híbridos: citrandarins ‘Indio’, ‘Riverside’ e ‘San Diego’, citrumelo ‘Swingle 4475’, HTR-051, TSKC x (LCR x TR)-040 e 059, LVK x LCR-010 e 038, TSKC x CTTR-002 e TSKC x CTSW-041, além de trifoliata ‘Flying Dragon’, limoeiro ‘Cravo Santa Cruz’ e tangerineira ‘Sunki Tropical’. Coletaram-se variáveis biométricas e fisiológicas, sendo o delineamento experimental em blocos ao acaso, em parcelas subdivididas, com 56 tratamentos, três repetições e dez plantas na parcela. Independentemente do porta-enxerto, a limeira-ácida ‘Tahiti CNPMF-02’ foi a copa mais vigorosa em viveiro, seguida da tangerineira-tangor ‘Piemonte’ e, por fim, pelas laranjeiras ‘Pera-D6’ e ‘Westin’. A tangerineira ‘Sunki Tropical’ induziu maior crescimento vegetativo e de sistema radicular em combinação com todas as copas estudadas. O trifoliata ‘Flying Dragon’ e o híbrido HTR-051 necessitam de maior período para a formação das mudas em função do menor vigor desses genótipos, em combinação com todas as variedades copas avaliadas. Não se observaram quaisquer sintomas de incompatibilidade entre as variedades no viveiro.
