Popularized eri spinning machine among farmers<br />
through training and practicing at traditional<br />
farmers’ level. Increase in yarn realization &<br />
production of finer count to get higher productivity<br />
& return<br />
Demonstrated in farmers fields. It is in practice at<br />
certain private farmers’ level. Introduced Ginger,<br />
Turmeric and Colocasia as intercrops in Som and<br />
Kesseru plantation for enhancing farm income.<br />
Two productive castor genotypes have been<br />
identified and introduced in the farmers field to get<br />
higher leaf yield.<br />
The protocol enables raising of plantlets from stem<br />
cuttings with a success rate of about 80%. The<br />
system facilitates propagation of desired<br />
genotypes, which hitherto were propagated<br />
through seeds.<br />
This reduces the gall infestation and facilitates<br />
availability of quality leaf for silkworm rearing.<br />
Indoor rearing of the chawki worms (up<br />
to 2 nd moult) ensures development of healthy<br />
worms with higher survival<br />
The combination SM5 increased the quality leaf<br />
yield by 27.45% in T. arjuna and 26.55% in T.<br />
tomentosa over control with significant<br />
improvement in cocoon characters<br />
The improved line of the Andhra local ecorace<br />
developed through hybridization with Daba shows<br />
higher fecundity (230), cocoon yield (26<br />
cocoons/dfl) and filament length (802 m) over the<br />
Andhra local ecorace (fecundity: 190, Cocoon yield:<br />
