For the production of honey, on a commercial basis, Italian variety of honey bee is reared. Apis mellifera is commonly used for honey production, throughout the country. This variety has been domesticated in India, due to its various good characters such as gentleness in nature, good honey collection capacity prolific queen production. with less swarming and a good ability to protect itseb from enemies. 

For the purpose of commercial production of honey, apiaries are established. For artificial rearing of bees, artificial hive is required. Artificial hive consists of a large brood chamber, wax coated metal plates and plastic plates. These plates form the base of artificial hive. These hives are kept in garden, to attract the bees. Blooming period is the most suitable time for artificial rearing. Drone bees are introduced. 

Drone bees secrete wax from their abdomen, producing glands. They start secreting wax on plates coated with toad. Drones prepare wax chambers on wax coated plates. When the honey chambers are filled completely, then plates are taken out and honey is collected. The wax deposited on these is also separated. 

Honey is very useful for health. It is also used in ayurvedic medicines. Wax obtained from bees is called bee wax, which is used in the preparation of polish, creams and shoe polish. Apiculture is used professionlly in these days. Khadi Gram Udhyog is encouraging apiculture, nowadays.

Rotation of crop is repeated cultivation of a cereal crop and a legume crop in successive seasons.

Manures and fertilisers are added to fields mainly to replenish minerals, which get depleted due to withdrawal by crop plants and reaching down to lower strata of soil. 

1. Manures add a small quantity of all minerals to the soil. They improve soil hydration, soil aeration and activity of soil micro-organisms, some of which are required for solubilisation of heavy minerals. 

2. Fertilisers are nutrient specific which contain one or more minerals in concentrated form. They meet the immediate and complete minerals requirement of high yielding varieties. However, they harm soil structure and cause pollution of crops, soil, groundwater and nearby surface water. A combination of both manure and fertilizer is highly useful.
