AbstractThe study was performed at the Experimental Station of Agriculture - Khan Krum in the period 2018-2019. The experimental plantation was established in 2001, the early Bigareau Burlat, middle early Bing and the late Germersdorfer and Van were tested. The planting material was produced on a mahaleb rootstock. The distance of planting was 6 meters interrow spacing and 5 meters intrarow spacing. The experiment was based on three replications each of them reported on a separate tree. When analyzing the frost percentage of flowers, 400 blossoms were taken from three levels of the crown of each tree, the same number of fruits were taken to determine the cracking percentage. Percentage of damaged blossoms, yield kg/ha and percentage of fruit cracking as a result of fallen rains during harvest were established. The purpose of the study is to investigate the influence of abiotic factors on the yield and quality of four sweet cherry cultivars. In this regard, the frost percentage in the range of values was 67,3 - 100%. Bigareau Burlat yield was not obtained, and it was relatively low from Germersdorf and Bing (20,1 - 24,6 kg/ha) at Van 84,6 kg/ha. The number of cracked fruits due to fallen rains during harvest was relatively high in Van and Bing (39,8 - 47,4%), while in the Germersdorf cultivar it was lower - 21,2%.

The study of rhizospheric microbial flora for the enhancement of aroma compounds is well recognized. The rhizosphere microbes also play very important role in improving medicinal values of plants. Rhizospheric microbes affect the plant physiology by imparting several useful effects such as nitrogen fixation, nutrient uptake, and production of secondary metabolites in the medicinal and aromatic plants. Recent days there are increasing the interests in the research of the relation between rhizosphere microbes associated with medicinal plant for the improvement of quality of medicinal plants. A large variety of fungi and bacteria is recognized in the rhizosphere soil of medicinal plants that showed significant effect in secondary metabolite alteration and uptake of plant nutrient. There are reports that rhizosphere fungi not only enhanced the growth parameters in plants but also considerably modulated essential oil’s quality. This study highlighted the researches performed on active role of rhizosphere fungi on explored medicinal and aromatic plants. As the use of organic material is one of the constituents of good agricultural practices (GAPs). Therefore, this review also investigates the environmental concerns reducing the use harmful chemicals as well as recommendation for utilization of biological and organics in agriculture. Therefore, a proper understanding of role of rhizosphere mycoflora associated with the medicinal plants is essential.

AbstractWith increasing interest in natural products of plant origin for medicinal and health care benefits there is added emphasis on the quality of the source raw material. In most cases the vegetative tissues and organs are the source of the required raw material. However, such tissues/organs may become infested/susceptible to many diseases causing deterioration of the quality of the desired economic product and loss of genetic resources. Considerable progress has been made with respect to the identification of disease causing organisms, and their pathogenic impact at organ, cellular and biochemical level. This review focuses on various diseases caused by bacteria, fungi, nematodes, viruses and phytoplasmas threatening the yield, biomass, bioactive potential of medicinal and aromatic plants of the sub-tropics. Several studies suggest that management of diseases through biological measures is more effective to check multiple diseases. Necessary management strategies for efficient disease management to realize quality raw material and enhanced metabolite productive potential have been outlined.

Coriander is an important aromatic plant of India. On steam distillation, the seeds yield a colourless or pale yellow volatile essential oil, which is used for flavouring food products, liqueurs, alcoholic beverages and perfumes. Coriander is also used in the synthesis of vitamin A (Bedoukian, 1967). The Central Institute of Medicinal and Aromatic Plants introduced several Bulgarian selections of coriander and evolved a superior variety, CIMPO S-33. This variety contains more essential oil (about 1·5%) than the local varieties available in India (0·2–0·3%) (Dimri, Khan & Narayana, 1976). Earlier work on coriander has shown that application of N (Bhupinder Singh et al. 1979) and N, P and K (Vagujfalvi, 1964) increases seed and oil yields of coriander. Information on nutrient uptake by coriander and on the effect of fertilizers on coriander oil quality is not available in India. The present experiment was designed to study the effect of different rates of nitrogen, phosphorus and potassium application on seed yield, yield and quality of essential oil and N, P and K uptake by coriander (cv. CIMPO S-33).
