For roguing inspect the pea field at least three, times: (I ) before flowering stage; ( 2 ) during flowering and fruiting; ( 3 ) during the mature fruit stage. A high standard of pureness to typ e allows 1 off-type plant in 200 plants. To avoid volunteer mixtures do not sow seed on land that has been planted to a different strain within the preceeding two years. Harvesting and Curing: Harvest the crop from the time the peas become hard in the pod up to the time they become completely mature. It takes about 30 days for the peas to sufficiently mature for germination after they reach their green stage. Put the vines in small bunches to cure for at least 10 days between harvesting and thrashing to allow the sweat to pass. Thrashing: thrasher. Seed Yield: Thrash the peas as soon as the plants dry. Thrashing can be done with an ordinary grain rare. The seed yield per hectare varies from 1.4 to 2 t. Seed yield as high as 2.5 t are also not \` 3
Seed Production Technology of Beans There are 18 types of beans found throughout the world. Of these, French bean (Phaselous vulgaris L.) lablab beans (Labial) purpureus), cowpea (Vigna sinensis Savi) and cluster bean (Cno ir &y /n /uboI.. Taub. ) are very common and popularly consumed as green vegetable in India. Except for cluster bean, the seed of the other three beans is also consumed as pulse. All these crops are self-pollinated and exhibit very little heterosis. Also because of the less number of seeds available in the pods economical commercial hybrid seed production is not possible. Hybrids can be made by hand emasculation and pollination only 1odevxlope a variety and for other improvements in the crop. The crops need 50-10 m isolation distance to produce foundation and certified seeds of two cultivars. French bean French bean is grown throughout the world as a green vegetable as well as for dry seed consumption as pulse. It is a self-pollinated crop with only 2-8% outcrossing. Climate French bean is uvvaoo-aeugoo crop in the hills but it does not thrive well under extremely high temperature. It cannot withstand drought as well as very heavy rainfall and frost. Even though, muoyculLivars are photo-insensitive, certain cultivars develop floral buds only during short days but would abscise during long days. Suitable soil temperature for good and rapid germination is 00C. Soil temperature ranging from 18 to 270C induce Rhizoctonia solani infection in young seedlings. High temperature exceeding 240C for two successive days can cause ureduction of 2% in the podsqt for each degree of temperature above 240C to 360F ( Davis 1945 ) . SburnmaeLul. (1983) found that 14-190C temperature and 60-70% humidity in autumn season and 20-250C and 50-70% humidity in spring season ared suitable for better growth and yield. Techniques for seed production French bean can be grown successfully in sandy loam soils. Alkaline and acidic soils should be avoided. To raise a good crop use 15-20 t FYM, 20 kg nitrogen, 60 kg phosphorous, and 60 kg potash. Except for nitrogen, other fertilizers should be mixed in the soil at the time of last plowing. Before sowing make sure that the soil contains sufficient moisture to attain better and quicker germination. Watering just after sowing or before germination results in germination failure. Seeds take 6 to 7 days at I50C soil temperature to germinate, germination is delayed at temperature below 150C. Sow seeds of dwarf types at a distance of 45-60 cm in rows; plant-to-plant distance should be kept at 15-20 cm. Pole types require 90-I00 cm distance between rows and 30-40 cm between plants. Nearly 50-55 kg seed for pole type and 75-100 kg seed for bush type are required to sow one hectare of land. Apply light irrigation and perform weeding and spraying of insecticide as and when required. Harvest ripe pods by hand. Dry the pods in the sun and thresh by beating with a stick. If plants are uprooted then curing must be done at least for 1 week so that pod color turns yellowish. Remove rotten and broken seeds at seed grading. After proper drying, keep the seed in store. Cowpea (Vigna oimuasio L.) Cowpea is grown throughout India for its long pods as green vegetable, seed as pulse, and foliage as fodder. When grown for dry seeds, it is known as black eye pea, kaffier pea, China pea, or southern bean. The cultivars grown for their immature pods are variusly known as asparagus 4
