PHARMD GURU Page 1 CONCEPT OF GOOD AGRICULTURAL PRACTICES (GAPs): These are specific methods which, when applied to agriculture, produce results that are in harmony with the values of the proponents of those practices. OBJECTIVES: 1. Ensuring safety and quality of produce in the food chain. 2. Capturing new market advantages by modifying supply chain governance. 3. Improving natural resources use, workers health and working conditions. 4. Creating new market opportunities for farmers and exporters in developing countries. CULTIVATION: It is a scientific approach to healthy growth of medicinal plant in large scale. The growth is defined as progressive development of the organs with respect to various factors. Some of the advantages of cultivations are: 1) Cultivation ensures quality and purity of medicinal plants. 2) It gives better healthy yield and therapeutic effects. 3) It minimizes biodiversity. 4) It supplies the raw materials to the industries throughout the year. 5) It provides disease free plants. 6) It increases industrialization and helps in unemployment problem.

PHARMD GURU Page 2 GENERAL STEPS FOR CULTIVATION OF PLANTS: METHODS OF CULTIVATION: Generally two types of cultivation are possible. (a) Sexual method (b) Asexual method (a) SEXUAL METHOD: In this method plants are cultivated from the seeds and such plants are called seedlings. This method is also known as seed propagation. Generally good quality seeds of high germination rate should be used for cultivation. Seeds should be free from other seeds and impurities. Examples: Mango, Lichi, Methi, Coriander, papaya, tomato. ADVANTAGES:  It is an easy method to cultivate plants.  It gives high yields.  It gives more number of varieties.  It is applicable for both monocot and dicot plants. DISADVANTAGES:  Sometimes it takes more time to grow.  Hybrid plant may not get.  Healthy plants may not get from the same field.  Asymmetric growth of the plants may occur.
PHARMD GURU Page 3 (b) ASEXUAL METHOD: Vegetative part of plant, such as steam or root, is placed in such an environment that develops new plant. Examples: Jasmine, sugarcane, potato, banana, rose. ADVANTAGES:  It gives high yield.  It develops hybrid plants.  It gives fruits and flowers throughout the year.  Quality of cultivated plant can improve.  This method is more useful for monocot plants. DISADVANTAGES:  It requires a skilled person.  Initially temperature and soil nature have to be controlled.  This method is time consuming.
PHARMD GURU Page 4 FACTORS INFLUENCING CULTIVATION OF MEDICINAL PLANTS: The most important parameter is factors on which the growth, variation of plant species depends. It also affects the quantity of the medicinally active compounds present in the plants and this greatly depends on the plant size. The variation depends on various factors (Fig. 2.3). An auxanometer is an apparatus for measuring increase or rate of growth in plants.
