Wind direction and velocity have significant influence on crop growth.

Climate is the most important dominating factor influencing the suitability of a crop to a particular region. The yield potential of the crop mainly depends on climate. More than 50 per cent of variation of crops is determined by climate. The most important cl

Solar energy provides light required for seed germination, leaf expansion, growth of stem and shoot, flowering, fruiting and thermal conditions necessary for the physiological functions of the plant. Solar radiation plays an important role as regulator and con

Relative humidity: It is the ratio of actual water vapour content to the saturated water vapour content at a given temperature and pressure expressed in percentage (%).

Cropping system can be planned by understanding the rainfall pattern. Rainfall analysis helps in taking decisions on time of sowing, scheduling of irrigation, time of harvesting etc., Rain analysis is necessary for designing farm ponds, tanks of irrigation pro

The following information indicates length of growing period for different district of Tamil Nadu. Based on the G period, suitable dry land crop may be selected.

Length of growing period is defined as a period in which the available soil moisture is enough to meet the evapotranspiration requirement of dry land crops and hence the dry land productivity is assured. The length of growing period is given as ‘G’ with starti
