A total <strong>of</strong> 4,307 farmers (2,474 in AP and 1,833 in Maharashtra) were trained in seed production, crop<br />
management, seed health, IPM, and post-harvest practices to ensure quality seed production. Farmers<br />
Day was also organized in Maharashtra with 351 farmers (including 21 women). During the project<br />
period, a total <strong>of</strong> 533 traders/dal mill operators in AP and Maharashtra were trained in seed storage,<br />
processing and marketing. Besides conducting training/seminars to farmers involved in seed production<br />
in AP and Maharashtra by ANGRAU and PDKV, respectively, a total <strong>of</strong> 699 extension <strong>of</strong>ficers, NGO<br />
staff, and private seed sector personnel were provided training in seed production, scientific storage,<br />
store grain pest management and marketing network.<br />

The seed production manual and pamphlets are published and distributed to farmers, village level<br />
workers and extension <strong>of</strong>ficials at the time <strong>of</strong> field days, trainings and meetings in AP and Maharashtra.<br />
Electronic and print media was effectively utilized <strong>for</strong> dissemination <strong>of</strong> package <strong>of</strong> practices <strong>of</strong><br />
pigeonpea production technology, field days, trainings, and exposure visit <strong>of</strong> farmers at ICRISAT in<br />
local newspapers and local radio/TV talks in AP and Maharashtra.<br />
During the three year period <strong>of</strong> the project, a total <strong>of</strong> 6,421 farmers attended the farmers’ field days/<br />
fairs in AP and Maharashtra. A total <strong>of</strong> 4,477 small seed packets (7,800 kg) <strong>of</strong> farmer-preferred varieties<br />
were distributed to farmers.<br />
Introduction<br />
The importance <strong>of</strong> improving access to quality seed in pigeonpea cannot be overemphasized due to<br />
its unique traits. Pigeonpea differs from other two legumes - chickpea and groundnut - in terms <strong>of</strong><br />
sensitivity to photoperiod (day length) and temperature, and natural out-crossing. The flowering response<br />
in pigeonpea is governed by a complex interplay <strong>of</strong> these two factors (photoperiod and temperature). It<br />
is categorized as a quantitative short-day plant and flowering initiates only when nights become longer<br />
than 14 hours. This has a potential implication <strong>for</strong> the seed producers since any delay in planting (from<br />
the normal sowing time <strong>of</strong> June- July) will result in reduced plant height and, there<strong>for</strong>e, low grain yield.<br />
Hence, the planting window available to the pigeonpea farmers is rather narrow. Other important<br />
constraint in seed production is the natural out-crossing in pigeonpea. It is one <strong>of</strong> the few legumes<br />
where natural out-crossing could be as high as 70%. This leads to rapid genetic deterioration <strong>of</strong> the<br />
seed quality in farmers’ fields. In order to avoid genetic contamination, pigeonpea needs a minimum <strong>of</strong><br />
300 m isolation distance. This poses a serious challenge in seed production, since in the target districts<br />
during the rainy season pigeonpea is extensively cultivated by farmers.<br />
