Soil Moisture status: The average soil moisture was highest in levelling land and bunding
fallowed by contour bunding and further in land shape techniques. Further it is indicated that
all in situ techniques recorded higher moisture conserve during the crop growth period as
compare to farmer’s practices.
Extension gap: Higher extension gap 12.9 q ha -1 was found during investigation years. This
extension gap should be assigned to adoption of improved transfer technology in
demonstrations practices resulted in higher seed yield than traditional farmer practices. This
emphasized the need to educate the farmers through various means for more adoption of
improved high yielding varieties and newly improved agricultural technologies to bridge the
wide extension gap. More use of new high yielding varieties by the farmers will subsequently
change this alarming trend of extension gap. The new technologies will eventually lead to the
farmers to discontinuance of old varieties with the new technology.
Technology gap: The demonstrations recorded the technology gap of 10.9 q ha -1 during the
study year, which was higher than that during 2016. The technology gap observed may be
attributed to dissimilarity in the soil and weather situation.
Technology index: The lower value of technology index is more feasibility. The technology
index was reduced average 45 per cent during the experimentation year, which shows the
higher feasibility of the demonstrated technology.
Gross and net monitory returns: Among the various technologies, land level and bunding
recorded higher average gross and net income (Rs. 63680 ha -1 and 38180 ha -1 ) as compared to
all other technologies and fallowed by contour bunding (Rs. 61000 ha -1 and 35500 ha -1 ).
However, the lowest gross and net monitory return was found with farmers practices (Rs. 52400
ha -1 and 26900 ha -1 ) in traditional method. Maximum B:C ratio recorded with bunding and
levelling (2.50) fallowed by contour bunding (2.39) over rest of the technologies. Therefore,
minimum B:C ratio was found with farmers practices (2.05).
