If the person is a pisciculturist does the breeding, hatching and rearing of fishes.

Pea and mustard are two examples of rabi crops.

(a) Fertiliser
(b) Crop
(c) Ploughing or Tilling
(d) Pisciculture

Water is necessary for all physiological functions and growth of all living organisms including plants. In summer, due to high temperatures, water evaporates from the soil as well as from plant surfaces thus making it deficient. This water deficiency is overcome by adequately supplying water to plants and taking care of them during summer season.

The levelling of ploughed field is beneficial because of following reasons:
(i) It prevents the top fertile soil from being carried away by strong winds or water.
(ii) It helps in uniform distribution of water in the fields during irrigation.
(iii) It also prevents loss of moisture from the ploughed soil.

The planting of a leguminous crop in a field has the same effect as adding nitrogenous fertiliser in the field. They can fix atmospheric nitrogen themselves by using nitrogen-fixing bacteria in their root nodules. Therefore, nitrogenous fertilisers are not required for growing leguminous plants.

Weeding - It is the removal of weeds from the field. It is essential as weeds are harmful for the growth of crops because they compete with the crop plants for water, nutrients, space and light.

Preparation of soil - It is the first step before sowing the crop. In this, the soil is ploughed to loosen it and make it aerated which allows the roots to breathe easily. This also helps earthworms and microbes in the soil that bring the nutrient rich soil to the top. The process of loosening and turning of soil is called tilling or ploughing, which is followed by levelling and manuring.

Besides the given tools, the other items required for raising a garden are seeds and seedling of vegetables, plants from nursery, kitchen waste, manure, water, soil.
Steps for raising the garden:
(i) Kitchen waste will be collected and composted in a pit.
(ii) A patch of land will be identified for the garden.
(iii) Soil will be dug up and levelled with the help of a spade.
(iv) Sowing of seeds/ transplanting of seedlings will be done.
(v) Select seeds/seedlings as per the season. Water the plants regularly with a water-can
(vi) Compost will be applied.
(vii) Weeds will be removed periodically with the help of khurpi.

The ability of soil to supply all the essential plant nutrients to a crop in adequate quantity is called soil fertility. Repeated growing of crops in the same soil removes various nutrient elements from the soil due to which the soil loses its fertility.
The soil fertility can be replenished or regained by the following methods:
(i) By keeping the field fallow (uncultivated) for one or two seasons.
(ii) By putting manures and fertilisers in the soil.
(iii) By practising crop rotation .
(iv) By practising multiple cropping (mixed cropping).
