Planting or sowing the crops at right time is quite important. Early planting may be one of the most cost effective ways of increasing crop yields. Since it costs no more to plant early than late, yields can be increased significantly by earlier planting without incurring any additional cost of production. Under Indian conditions time of sowing of crops varies with the choice of the crop, availability of soil moisture and irrigation facility. However, there are specific seasons for achieving high crop yields.
Under irrigated conditions (garden-lands), since water is available throughout the year, crops are grown according to the season throughout the year. Timely planning is important to get higher
Under dryland conditions, sowing of medicinal crops depends on the receipt of rainfall and availability of soil moisture. Early sowing utilizes the soil moisture more effectively. The crop puts forth early vigor, growth and development resulting in higher production. Normally kharif sowing is taken up with the onset of South-West monsoon during June- July. The rabi season crops are sown in the residual soil moisture from October to early November.
