SUMMARY

There is a big gap in demand and supply of fodder/feed for the increasing livestock in India, which calls for the use of unconventional sources as fodder/feed for livestock. Rice-wheat is the major cropping system in Indo-genetic plains of India and now-a-days more than 75% area is combine harvested. Wheat straw is used for feeding the livestock, but most of the combine harvested rice straw is burnt in the fields due to less turnaround time between harvesting and planting of subsequent crop and non-availability of suitable machines for its management/removal from the field. If rice straw can be removed from the field with proper machinery and treated for improving its digestibility for feeding the livestock, the gap between demand and supply may be bridged. The tractor drawn paddy straw reaper was evaluated at farmers field at Ludas village of Hisar district for optimization of machine parameters viz., cylinder speed (550, 750 and 950 rpm), forward speed (1.0, 1.5 and 2.0 km/h) and crop parameter viz., moisture content (20.8 to 50.2 %) in relation to field capacity, fuel consumption, straw size and straw recovery in paddy variety Pusa-44. The field capacity, fuel consumption, straw size and straw recovery at optimum conditions were 0.20 ha h^-1, 5.66 l ha^-1, 3.46 cm and 62.89 %, respectively. Moisture content of 20.8 per cent, forward speed of 1.5 km h^-1 and cylinder speed of 950 rpm was found optimum for paddy variety Pusa-44.

Key words:Paddy straw reaper, cylinder speed, field capacity, forward speed, fuel consumption, moisture content

SUMMARY

KVK, Chandgothi, Churu (Rajasthan) conducted total 149 Front Line Demonstrations on cluster bean at farmers field in Churu District (Rajasthan) during six consecutive kharif seasons from 2012 to 2017. The farming situation was rainfed and soil was sandy loam low in nitrogen, medium in phosphorus and medium to high in potash. Assessment of gap was done and on basis of gap assessment, improved recommended technologies were demonstrated. On overall average basis, 1212 kg/ha grain yield was recorded under demonstration plot while 1039 kg/ha in farmer’s practices. On the basis of six year average, 16.77 % higher grain yield was recorded under demonstrations than the farmer’s traditional practices (Local check). The extension gap, technology gap and technology index were 173 kg/ha, 197 kg/ha and 13.62 %, respectively. An additional investments of Rs. 1000/ha consist with scientific monitoring of demonstration and non–monetary factors resulted in additional return of Rs. 10252/ha. On six year average basis incremental benefit : cost ratio was found 9.98.

Key words:Cluster bean, grain yield, economics, technology gap, extension gap
