Extreme rainfall events, prolonged dry spells and waterlogging at different crop growth stages.
Generally farmers of Sanora and Barodi village, Datia sow soybean with local country plough which is time and labour intensive. During extreme rainfall events, the crop gets affected either due to dry spells or waterlogging due to lack of proper drainage.
There is a need for in-situ soil and water conservation and proper drainage technology in deep black soils. Broad bed and furrow (BBF) system involves preparation of a broad bed of 90 cm, furrow of 45 cm and sowing of crop at a row spacing of 30 cm. The cost of BBF implement is Rs. 45,000. The BBF technology has many advantages including in-situ conservation of rainwater in furrows, better drainage of excess water and proper aeration in the seedbed and root zone. More than 200 farmers in Sanora and Barodi village adopted the technology. Similarly, furrow irrigated raised bed (FIRB) planting was promoted for cultivation of different crops in Uttar Pradesh, West Bengal, Punjab, Maharashtra, Karnataka, Rajasthan and Tamilnadu. Ridge and furrow method of vegetable cultivation was promoted in Gunia village of Gumla district and in cotton at Amravati and Aurangabad, Maharashtra.
Advantage of BBF planting method :
Performance of soybean in ridge and furrow method of sowing
|Particular||Ridge and Furrow||Farmers’ practice||% increase in yield/income|
|Grain yield (kg/ha)||1937||1152||40.5|
|Net Return (Rs/ha)||38805||18898||51.3|
|Water use efficiency (kg/ha/mm)||2.09||1.24|
Advantages of FIRB planting method are:
Ridge and furrow method of vegetable cultivation in Gunia village of Gumla district had the following advantages:
BBF / FIRB / Ridge furrow planting of crops was demonstrated in Coochbehar (West Bengal), Kushinagar (U.P.), Baramati, Amravati, Aurangabad, Nandurabar (Maharashtra),Nalgonda (A.P), Kota, (Rajashthan) Datia, Morena, Satna (M.P) Chikballapur (Karnataka) and Villupuram (Tamilnadu) in 412 ha covering over 1000 farmers with an average 10 to 40% increase in yield and benefit cost ratio of 2.2 to 4.7 compared to farmers’ practice. There is scope for upscaling the technology in soybean, maize and wheat growing areas.
