Varieties or strains of crops can be selected by breeding for various useful characteristics such as disease resistance, response to fertilizers, product quality and high yields. Crop variety improvement is the manipulation of crop plants for increasing their yield and improving quality.
Some of the factors for which variety improvement is done are:
• Higher yield: The main aim of crop improvement is to improve the productivity of the crop per acre.
• Improved quality: Quality considerations of crop products vary from crop to crop like baking quality is important in wheat, protein quality in pulses, oil quality in oilseeds and preserving quality in fruits and vegetables.
Fertilizers are commercially produced plant nutrient that enriches the soil fertility and increases the crop yield. They supply nitrogen, phosphorus and potassium. They are used to ensure good vegetative growth (leaves, branches and flowers), giving rise to healthy plants but they should be applied carefully in terms of proper dose, time, and observing pre-and post-application precautions for their complete utilisation. For example, sometimes fertilizers get washed away due to excessive irrigation and are not fully absorbed by the plants. This excess fertilizer then leads to water pollution.
Continuous use of fertilizers in an area can destroy soil fertility because the organic matter in the soil is not replenished and micro-organisms in the soil are harmed by the fertilizers used.
