As opposed to direct sowing, production of seedlings of vegetable crops for transplanting is commonly practiced by vegetable growers. This study was undertaken to determine the effects of humic acid on the growth and the macro and micro nutrients contents in tomato (<i>Lycopersicon esculentum</i>) and eggplant (<i>Solanum melongena</i> var. <i>esculentum</i>) seedlings under greenhouse conditions. Different levels of humic acid (50, 100, 150, 200 ml l<sup>-1</sup>) were applied to growing media (peat) after transplanting of examined seedlings of the species every ten days by the time of planting. The highest growth rate for leaf stem and root growth were obtained at 50 and 100 ml l<sup>-1</sup> HA and 50, 100, 150 ml l<sup>-1</sup> HA for tomato and eggplant seedlings., respectively as compared to the control. The highest content of macro and micronu trient contents were obtained at 100 ml l<sup>-1</sup> HA and 200 ml l<sup>-1</sup> HA for tomato and egg plant seedlings, respectively as compared to the control.

The research work investigates the metal uptake of the plants Lycopersicon esculentum (tomato), Rumex acetosa (sorrel), and Solanum melongena (garden egg) collected from experimental sites and a control area in Zaria, Nigeria. The concentrations of Cd, Cu, Fe, Pb, Mn, and Zn in different parts of each of the plant species grown on the experimental and control soils were determined using atomic absorption spectrophotometry. The experimental levels of the metals were higher than those at the control site and the limits recommended by Food and Agricultural Organisation/World Health Organisation (FAO/WHO). Solanum melongena showed bioaccumulation factor (BF) and transfer factor (TF) greater than 1 for Cd, Pb, and Mn; Rumex acetosa showed BF and TF greater than 1 for Mn and Zn, and TF was greater than 1 for Cu and Fe; Lycopersicon esculentum had only the TF for Fe, Pb, Mn, and Zn greater than 1. This results implies that Solanum melongena and Rumex acetosa plants can be effectively used for phytoremediation of Cd, Pb, Mn, and Zn from the dumpsite. Pearson’s correlation coefficient values (r) were greater than 0.75 for all the metals studied which indicated that the high metal level in the experimental soil was a result of the metal-scrap.

: N-phenylphthalamic acid — Cl4H1 1 NO3 (Nevirol 60 WP) was successfully used for enhancing yield in some important vegetable crops namely, tomato (Lycopersicon esculentum), chilli (Capsicum annuum) and brinjal (Solanum melongena) of Solanaceae. Aqueous sprays with 0.2% and 3.0% significantly enhanced fruit production in chilli and tomato respectively. On the other hand, various treatments in brinjal failed to enhance yield significantly. The increase in yield in both tomato and chilli is largely due to increase in the number of flowers and fruit-set percentage.

RESUMO Óleos essenciais (EO) e extratos brutos aquosos (EBA) de Syzygium aromaticum e Cymbopogon nardus, e seus principais componentes químicos foram investigados para controle in vitro e in vivo de doenças causadas por Phytophthora nicotianae em tomateiro (Lycopersicon esculentum) e berinjela (Solanum melongena). Experimentos in vitro foram conduzidos pelo método de diluição em ágar com diferentes concentrações de óleos essenciais (OE’s) (0,1; 0,5; 1,0 ?L/mL) e extratos aquosos brutos (EBA’s) (1,0; 10,0 20,0%) para avaliar o potencial inibitório sobre o crescimento micelial e germinação de zoósporos. Com as porcentagens de inibição e concentrações inibitórias mínimas encontradas, realizou-se testes em frutos e plântulas sob ambiente controlado. As variáveis avaliadas foram o diâmetro médio das lesões formadas na superfície dos frutos e a incidência e morte de plântulas ao longo de seis e 15 dias de avaliação, respectivamente. Os produtos que mais inibiram o crescimento micelial e a germinação de zoósporos foram obtidos de S. aromaticum, nas concentrações de 0,5 ?L/mL e 10% de OE e EBA, respectivamente. Os tratamentos que mais retardaram a progressão da doença em frutos e plântulas, em comparação com o controle, foram o OE e EBA de C. nardus a 1,0 ?L/mL e 20%, respectivamente. Portanto, os produtos obtidos de S. aromaticum e C. nardus, têm potencial para reduzir o ataque deste patógeno em tomate e berinjela.

Durante 1998 e 2000, a incidência de murcha bacteriana causada por Ralstonia solanacearum foi registrada em 25 municípios do estado do Amazonas. A bactéria foi encontrada nas seguintes espécies vegetais: Capsicum annuum, C. chinense, C. frutescens, Cucumis sativus, Heliconia sp., Lycopersicon esculentum, Melanthera discoidea, Moringa oleifera, Musa sp., Solanum melongena, S. gilo, e S. nigrum. Em tomateiros (Lycopersicon esculentum), a murcha bacteriana estava presente em todos os plantios. Em bananeiras (Musa spp.), a incidência do Moko foi menor nas várzeas dos rios Madeira e Negro do que nas dos rios Solimões e Amazonas. Caracterizaram-se 320 isolados de R. solanacearum, obtidos no levantamento, com relação a raça e a biovar. A biovar 1 predominou em todos os hospedeiros, com exceção de C. annuum e C. chinense, onde estirpes da biovar 3 foram maioria. Apenas 7,8% das estirpes foram da biovar N2. A sensibilidade de 56 estirpes da raça 1 a 23 bacteriocinas foi avaliada. As estirpes da biovar 3 apresentaram uma menor variabilidade, na sensibilidade a bacteriocinas do que as estirpes das biovares 1 e N2.
