An experiment in Gujarat on castorseed has yielded double the output over conventional farming, without significant change in farm practices or additional expense.
It has been conducted over 160 hectares in six districts, using the GCH-7 variety of higher yielding seed, developed by Sardarkrushinagar Dantiwada Agricultural University (SDAU), Palanpur. The output per hectare it has reported, from most areas, is an average of four tonnes. Conventional means have not given more than two tonnes per ha.
