Question

Why do cultivation practices and crop yield are related to environmental conditions?

Answer 1

Cultivation practices are a collection of principles that are applied as on-farm production and the post-production processes to produce safe and healthy crop. Cultivation practices include soil preparation, seed selection, sowing, irrigation, fertlisers and manure, crop protection, weeding, harvest and storage.
Cultivation practices and the crop yield are closely related to environmental conditions. Environment provides soil, water, temperature, humidity , day-length etc to the crops.
*Soil with good percolation rate, water holding capacity helps in proper growth of the crop and increases its yield. 
*Selection of good seeds give rise to healthy plants in the crop which can produce good yield. 
*Irrigation plays a main role in nourishing the crop and increasing its yield.
*Manuring helps in supply nutrients to the growing crop thereby increasing its yield. 
*Weeding also helps in healthy growth of the crop thereby producing good yield.
*Day-length is the period of time during which crops are exposed to the sunlight. Sunlight plays an important role in flowering and seed production in plants.
