A grower can only get a realistic assessment of the cost of production of a specific horticultural crop if he can register all the different tasks in cultivating that crop. BeTa is a programme which uses a simple barcode registration system to ascertain the time involved in different task areas. KuKa is an additional programme which uses the collected date from BeTa to give the grower a complet...
The structural transformation brings changes to new technology in the form of high-yielding seeds, fertilizers and pesticides adoption modern improved farm practices since mid-1960s. However, after mid-1980s, growth rate agricultural economy started decelerating. Results revealed that during overall period, area, production yield was negative for field crops except rice wheat. For fruits vegeta...
