“…A significantly higher total herbage yield (39.25 t ha -1 ) was obtained with 300 kg N ha -1 year -1 compared to the unfertilised control (18.59 t ha -1 ). These results agree with the findings of Singh (2004). A similar pattern was noticed in the case of oil yield.…”

“…Rosemary was introduced in the late 1980's to the semiarid tropical climate of Bangalore, India, where the red and lateritic soils are deficient in available N, and low-tomedium in available P and K (Gopal Rao et al, 2000). The crop normally responds to the application of N fertilisers (Prakasa Rao et al, 1999;Singh and Ramesh, 2000;Singh, 2004). Favourable effects of N application for enhancing the herbage and oil yields of various aromatic crops [e.g.…”

Essential oil of rosemary (Rosmarinus officinalis L.) possesses good olfactory properties and is suitable for use in perfumes, soaps and fragrances. Field experiments were conducted over 2 years (2003)(2004)(2005) in an area experiencing a semi-arid tropical climate, to study the influence of two N levels (150 or 300 kg N ha -1 year -1 ) and three K levels (41.5, 83.0 or 124.5 kg K ha -1 year -1 ), or no fertiliser, on the growth, herbage and oil yields and nutrient uptake patterns of rosemary. The results showed that application of 300 kg N ha -1 year -1 produced higher herbage and oil yields in rosemary, compared with 150 or 0 kg N ha -1 year -1 . The application of 83.0 kg K ha -1 year -1 produced maximum herbage and oil yields, compared with 0 or 41.5 kg K ha -1 year -1 . Total N and K uptake levels were increased significantly by the application of N and K. Nitrogen uptake increased by 85.2% and 137.7%, and K by 80.9% and 123.9%, respectively, with the application of 150 or 300 kg N ha -1 compared to controls (no N). Similarly, N uptake increased by 96.1%, 130.2% and 113.6%, and K by 79%, 124.3% and 110.4%, respectively, with the application of 41.5, 83.0, or 124.5 kg K ha -1 compared to controls (no K). Oil content and oil composition were not influenced by nitrogen or potassium levels.

“…As plantas cultivadas sob níveis reduzidos de água no solo diminuem o crescimento e investem no ajuste osmótico. Dentre os solutos envolvidos no processo de ajustamento osmótico, a prolina tem aparecido na literatura como sendo um aminoácido particularmente sensível ao estresse (Hopkins, 1995;Larcher, 2004), usado como estratégia para se adaptar à condição de estresse hídrico (Singh-Sangwan et al, 1994). De acordo com Machado Neto et al (2004), o acúmulo de aminoácidos, como a prolina, pode ser utilizado para avaliar as alterações enzimáticas ocorridas como respostas bioquímicas para mudanças no ambiente tais como temperatura, déficit hídrico, encharcamento e salinidade.…”

Palavras-chave: Calendula officinalis, manejo da irrigação, tanque classe A ABSTRACT: Flavonoid content and yield in marigold plant (Calendula officinalis L.) cultivated under different irrigation depths.Calendula officinalis L. presents ornamental, culinary and therapeutic use. Its inflorescence is used to heal and as an anti-inflammatory. This study analyzed the effect of four different irrigation depths under field conditions on flavonoid production in marigold plant (Calendula officinalis L.). The water depths were estimated based on the class A pan evaporation (CPE): 0, 50, 100 and 150% CPE; they were applied from the beginning of flowering to the end of the culture cycle. There were no statistical differences in flavonoid content. The highest values of flower dry weight and flavonoid yield were obtained with the treatment without irrigation. The highest proline content was found in the plants subjected to overwatering stress. The accumulated water deficit for the treatment without irrigation signalized possible death due to water deficit. As precipitation occurred in the pre-flowering, the plant, originated from Mediterranean, responded with an abundant flowering in mass and number of flowers. Thus, for Presidente Prudente (São Paulo State, Brazil), if there is no water replacement through precipitation, supplementary irrigation with 200 mm will be necessary only in the pre-flowering to induce maximum flowering and maximum flavonoid yield per hectare.

RESUMO.O manjericão (Ocimum basilicum L.) é uma planta aromática de importância econômica no Brasil, muito usado como tempero na preparação de alimentos. É também utilizado para a obtenção de óleo essencial, importante na indústria de perfumaria. O objetivo deste experimento foi analisar o efeito de cinco lâminas de irrigação, bem como uma análise da viabilidade econômica da aplicação da irrigação na produção do manjericão. O experimento foi conduzido no período de março a outubro de 2007. As lâminas foram baseadas na evaporação do Tanque Classe A (ECA) sendo: 0, 50, 75, 100 e 150% ECA. As variáveis analisadas foram matéria seca das folhas e inflorescências, teor de óleo essencial, massa seca e comprimento de raízes. Foram calculadas a produtividade de óleo essencial e a receita líquida. A terceira colheita foi viável somente utilizando irrigação. A irrigação diária excessiva prejudicou o desenvolvimento da planta. A lâmina de irrigação equivalente a 100% ECA promoveu a máxima produtividade de matéria seca (4.248,67 kg ha ABSTRACT. Effect of different water depths in basil (Ocimum basilicum L.) oil production. Basil (Ocimum basilicum L.) is an aromatic plant of economic importance in Brazil, very used as a spice for food preparation. It is also used to obtain essential oil, which important in the perfume industry. The purpose of this experiment was to analyze the effect of five irrigation water depths, as well as an economic viability analysis of the application of irrigation in basil production. The experiment was carried out from March to October 2007. The water depths were based in the cumulative class A pan evaporation (CPE): 0, 50, 75, 100 and 150% CPE. The analyzed variables were dry weight for leaves and flowers, content of essential oil, and dry mass and length of root zone. The essential oil yield and net return were calculated. The third harvest was possible only under irrigation. The daily excessive water depth was detrimental to plant development. The 100% CPE water depth showed the maximum dry mass productivity (4,248.67 kg ha
