Vegetables play an important role in the growth and development of the body. In order to maintain the nutritional properties of vegetables, Agriculture experts have given some beneficial suggestions and the nutritional properties can be preserved by following those suggestion. Due to insect pests and diseases 20-30 percent production decreases and sometimes the whole crop is damaged. So it is important to protect the crop from harmful pest and disease so that the production is not effected and hence nutritional profile of vegetables will be preserved.
For the control of harmful pests and insects right and safe pesticides should be used. Those pesticides should be avoided whose effect remains for long duration. Harvesting vegetables at appropriate time is necessary for maintaining the nutritional profile. For example when melons are harvested before appropriate time, then the sugar content and sweetness decreases. Likewise, when bottle gourd, lady finger and pumpkin are harvested lately then they become very hard and cannot be used for cooking purpose. For selling vegetables at Mandi, vegetables should be harvested in evening time so that fresh produce can be sell the next morning. If the weather is hot then vegetables should be harvested at evening time and they should be kept at dark place in order to protect from heat.
