Abstract:Pulses are the important sources of proteins, vitamins, minerals and are popularly known as Poor man’s meat” and “rich man’s vegetable”, contribute significantly to the nutritional security of the country. Besides being rich organic source of protein, they maintain soil fertility through biological nitrogen fixation and improve the soil organic matter by defoliation at maturity. Hence, they occupy prominent place in various inter cropping systems and crop rotations. Thus pulses play a vital role in furthering the sustainable agriculture Pulses are a vital source of plant-based proteins and amino acids for people around the globe and should be eaten as part of a healthy diet to address obesity, as well as to prevent and help manage chronic diseases such as diabetes, coronary conditions and cancer; they are also an important source of plant-based protein for animals. Pulses accounts for 42.34 and 36.86 percent of total world pulse area total world’s pulse production respectively (Agricultural statistics at a glance, 2016).
Plant growth retardants play key role in contributing internal mechanisms of plant growth by interacting with key metabolic processes such as, nucleic acid metabolism and protein synthesis. Growth retardants are known to reduce inter-nodal distance, thereby enhancing source-sink relationship and stimulate the translocation of photo-assimilates to the seeds (Luib et al., 1987). Growth regulators exert their influence on foliar transport in a number of ways. These could enhance the absorption by the leaf at the site of application, increase the migration within the leaf and stimulate the transport out of leaf in the acropetal and basipetal direction.
