Answer 1

1. Agricultural machinery is machinery used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the countless kinds of farm implements that they tow or operate. atmospheric nitrogen into ammonia . This ammonia is being used by plant in the form of protein. pulses are alternated with other crop to full fill the demand of protein of other plant .
2. Pulses are leguminious plants which contain nitrogen fixing bacteria like RHIZOBIUM which convert atmospheric nitrogen into ammonia . This ammonia is being used by plant in the form of protein. pulses are alternated with other crop to full fill the demand of protein of other plant .increases as the rate of evaporation from leaves and soil become higher and in the winters the frequency of soil gets a decrease due to a lower rate of evaporation. Nature of the soil: another important factor on which time and frequency of irrigation depend is thee nature of the soil

Answer 2

Answer:

1) Agriculturall machinery is machinery used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the countless kinds of farm implements that they tow or operate.

2) Pulses are leguminious plants which contain nitrogen fixing bacteria like RHIZOBIUM which convert atmospheric nitrogen into ammonia . This ammonia is being used by plant in the form of protein. pulses are alternated with other crop to full fill the demand of protein of other plant

3) increases as the rate of evaporation from leaves and soil become higher and in the winters the frequency of soil gets a decrease due to a lower rate of evaporation. Nature of the soil: another important factor on which time and frequency of irrigation depend is thee nature of the soil.

4) Answer: The process of watering the crops is called irrigation. Two methods of irrigation are: (i) Sprinkler system : This system is used on the uneven land where less water is available. The perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals.

5) The leguminous plant increases the soil ripeness due to the Rhizobium bacteria in the root knobs of the plants. These microscopic bacteria changes over atmospheric nitrogen to a shape which can be utilized by plants. This reduces the nitrogen deficiency in the soil and makes it abundant.

6) If seeds are sawn too deep in the soil the seed will not germinate due to the lack of air in the wet soil. ... The plumule that usually comes out at the time of germination will fail to come up through the wet soil.
