crop cutting method. Qualitative data were converted into quantitative form and expressed in
terms of per cent increase in yield calculated using following formula:
(Potential yield – Demonstration yield)
Technology index = X 100
(Potential yield)
Technology gap = Potential Yield – Demonstration yield
Extension gap = Demonstration yield – Farmers practices yield
(Improved practices – Farmers practices)
% increased over farmers practices =
(Farmers practices)
X 100
Tabular analysis involving simple statistical tools like mean was done by standard formula to
analyze the data and draw conclusions and implications. For technologies, different extension
approaches were made. In this region was supplied with moisture conservation technologies
through KVK, Chitrakoot because more than area is to be found in undulated situation. The
technology could successfully out yield all other farmers practices and recorded eye-catching
higher yield. During 2018, the area under technology expanded horizontally to 120 hectares
from a mere 2.5 hectare during first year (2015) of introduction and adopted by 31 farmers in
2 villages. Due to efforts of KVK, scientists field visit, interpersonal communication and
individual efforts of the farmers, the technology could spread to more than area of district.
Results
Effect of in situ moisture conservation practices on grain yield: Results of in situ moisture
conservation techniques demonstrations was conducted during rabi 2015 and 2016 at farmers
field. During the investigation years, the maximum chick pea grain yield was recorded with
land levelling and bunding fallowed by mulching as compare to farmer practice. The enhanced
grain yield 17.71% with creation of bunding and levelling as compared to farmers practices.
The creation of land levelling and bunding to improve the soil moisture and nutrient availability
resulted that enhanced yield over farmers practices. Improved soil moisture was mainly due to
stay of water in field and reduced runoff intensity of water which facilitated better crop growth
and yield of chick pea.
