An Overview on Marigold: Beyond Beauty and Décor | Chapter 5 | Current Topics in Medicine and Medical Research Vol. 9

 In South Asia, marigolds were well known and respected by ancient people. In the daily life of the Indian sub-continent, the vivid orange and red colours of marigolds are seen everywhere. They are primarily decorative plants, although in all kinds of ceremonies, including weddings, flowers are used. In South Asian medicine, Marigold has been used rarely. In particular, marigold leaves and flowers have been used for different disorders. Marigold species are being studied for their possible health benefits. They are now being used for several days for the treatment of different diseases. Calendula as an effective treatment for different conditions has not yet been proved by any clinical review or analysis. The use of marigold, however has shown promise in treating various illnesses. So Marigold may be the most powerful remedy of choice for different diseases, and this new study will undoubtedly help mankind lead a safer and disease-free life.

Measurement and Estimation of Crop Coefficient of Plastic Greenhouse for Marigold (Tagetes erecta (L.)) under Drip Irrigation| Chapter 11 | New Perspectives in Agriculture and Crop Science Vol. 3

 Depending on the type of crop, stage of production, soil and climatic conditions, crop water consumption (ETc) varies from region to region. The water demand of the cultivated plants should be determined accurately and irrigation water should be applied according to plant requirements in order to obtain optimum yield and avoid unnecessary water usage. In this analysis, the growth stage specific crop coefficient (Kc) and pan coefficient (Kp) for greenhouse-grown marigold (Tagetes erecta (L.)) were calculated in field No.C3 of the Central farm at the Agricultural Engineering College and Research Institute, Kumulur, Trichy district. Since a Class A pan occupied a wide area, a reduced evaporative pan size (20 and 60 cm compared to a Class A pan) was used and a pan coefficient of 0.93 and 0.96 respectively was calculated. For the transformation of pan evaporation (Epan) to grass reference evapotranspiration (ETo), a pan coefficient (Kp) was used. The depleted moisture content was taken to estimate the crop coefficient for different growth phases based on the tensiometer readings. The results showed that the marigold crop coefficient (Kc) was 0.37 during the initial stage (Kcin), 0.8 during the mid-stage (Kcmid) and 0.47 (Kcfin) during the final stage. Such findings will be helpful in needing crop water and scheduling irrigation for similar conditions.
