Irrigation Scheduling and Plant Growth Regulators

Clusterbean crop production affecting by various production factors viz. spacing, seed rate, sowing time, dose of fertilizers, methods and time of fertilizer application, irrigation, use of plant growth regulator etc. play an important role in the maximization of green pod of clusterbean production per unit area. Among the various factors of production, irrigation schedules (IW: CPE ratio) and use of different growth regulators play pivotal role in increasing the clusterbean production. Water is the basic input for increasing crop production. Agricultural Productivity cannot be maintained without assured supply of moisture to the plant, which is accomplished by irrigation. Scheduling of irrigation based on the data of the pan evaporation is likely to increase agricultural production at least to the tunes of 15-20 percent. Among various strategies employed to increase crop yield, use of plant growth regulators have great promise due to modified crop growth by changing the rate or pattern of growth or both. Plant growth regulators are known to influence the growth and development of plants and ultimately the yield and yield attributing characters.
