25105 Bio-pesticide for oilseed, pulse and vegetable crops
Ashok, 50, having two acres of land, makes a pesticide by mixing one kg of makrod (mottled ebony, Diospyros cordifolia Roxb.) leaves or fruits, one kg of neem seeds and 250 g of gum from babul (Vachellia nilotica (L.) P.J.H.Hurter & Mabb.) tree and 250 g of urea, in about five to six litres of water.
He boils the mixture to half. After allowing it to cool, he filters the mixture and dilutes it 20 times. It is applied 2-3 times at an interval of 15-20 days. The diluted mixture is effective on rapeseed, cauliflower, cabbage, tomato, brinjal, chilli and pulse crops. About 50-60 litres are consumed per acre.

25106 ‘Abu Saunf 440’ - Improved fennel variety and improved package of practices
Ishaq Ali has selected an improved variety of fennel named as ‘Abu Saunf 440’. His father, Ibrahim, had migrated from Gujarat and was keen on growing fennel as he found the condition suitable for the crop. The family started selecting the best plants from about 32 local varieties available in the region. The basic criteria of selection were: number of grains per umbel, number of umbels per plant, greenness of fennel seeds, maturity period and disease resistance. The new variety gives nearly twice the average yield (28 to 30 q/ha against 10 q/ha given by other local varieties and a slightly longer maturation time 250 to 280 days against an average of 207-215 days). The number of seeds per umbellets and the number of umbels is significantly higher than others.
Ishaq also has been able to get better results by using the paired row method of planting in transplanted fennel. Previously, fennel was transplanted at a spacing of 90x40 cm or 100x60 cm. The innovator noticed that with such spacing, the crop was prone to disease and insect infestation like blight, gummosis and aphid. Moreover, much water was consumed. He modified the rows and planted at paired row spacing of 120 cm and spacing between two pairs was 210 cm. It saved water by about 55 per cent as the 120 cm spacing rows are only irrigated and the 210 cm rows spacing ones remain unirrigated. Humidity is lowered due to the intervening dry space of 210 cm between every alternate row which further reduces the incidence of blight and aphids diseases. This also facilitates easy weeding and harvesting of crop.
Proper drying of the seeds is important for retaining the color and the essential oils, Ishaq has designed an indigenous shade house using bamboo, bajra and sorghum stalks where the crop is dried. With not just an improved variety, but also an improved way of cultivation and post-harvest technology, Ishaq is able to reap a good crop every year.

25107 Herbal preparation for pests control in vegetable and paddy crops
While Badri Mahato could study only upto class seven, he has a very good knowledge of different plants for pest management. He makes pesticide from the extract of bitter vine i.e.Mikania micrantha Kunth by boiling one kg of the chopped plant, also called “American rope” with about two litres of water. He uses only the aerial portion (shoot, leaf and fruits- green or dry) of the plant. The extract is filtered and then sprayed on paddy crop. Three sprays at a ten-day interval are generally effective. For spraying one acre, 1.5 litres of the mixture is sufficient. The plant extract can be stored up to 6 months into closed glass jars for long storage. The extract should not be applied during the rainy season.

Application of the plant extract and volatile oil compounds of M. micrantha is reported for their insecticidal properties (Zhang , et. al., 2004.Insect Science, 11(1), 37–45). Botanical extract of M. micrantha is reported for its toxic effect against hispine beetle and grasshoppers. Its antimicrobial property against Bacillus subtilis and Escherichia coli. is also reported (Pérez-Amador, et. al., 2010. Phyton, 79, 77.)
