what is the main factor that affects humidity
raghu37:
The air that we breathe is made up of numerous gases, including water vapor. The term humidity generally refers to the amount of this water vapor in the atmosphere. Each atmospheric gas has its own vapor pressure, a measure of the number of molecules present at a given temperature. The vapor pressure of water thus measures the amount of water vapor in the air.

Humidity, by any of a variety of measures, is a function of the amount of water vapor in the air. Relative humidity is one measure of that - it is the ratio of the actual water vapor content relative to the water vapor in air that is saturated with respect to water vapor. The water vapor content at saturation is a function of temperature, increasing as the temperature rises. There are many other ways to measure humidity, such as the dew point temperature, the water vapor pressure, and others.

The main factory that affects humidity are as follows -
☆ water relations.
☆ Leaf growth.
☆ photosynthesis.
☆ Pollination.
☆ Peasts.
☆ Green yield.
This above answer is only for 1-2 marks. I am also giving you the answer for 4-5 marks.
The main factors that affects humidity are given below -
¤ Relative humidity has considerable influence on evapotranspiration and hence on the water requirement of crops. At constant temperature, changes in atmospheric humidity affect transpiration by modifying the vapour pressure gradient from leaf to air.
¤ Photosynthesis is indirectly affected by Humidity. When the humidity is low the rate of transpiration increases causing water deficits in the plant. Water deficits results in incomplete or complete closure of stomata and increases mesophyll resistance blocking entry of carbon dioxide.
¤ Moderately low air humidity is favorable for seed set in many crops provided soil moisture is adequate.
¤ The incidence of insects’ pests and diseases is high under high humidity conditions. High RH favors easy germination of fungal spores on plant conditions. Numerous insects such as aphids and jassids flourish better under moist conditions.
¤ Very high or very low RH is not conductive for high grain yield. Under increased humidity condition, RH is negatively associated with grain yield of maize.
