Pea (Pisum sativum L.) is an important nutritious leguminous cool season crop grown
throughout the world mostly during cool seasons. Pea crop is a rich source of protein,
carbohydrates, vitamin A, vitamin C, calcium, phosphorous and several amino acids (Pandey
and Uniyal 2018). Pea crop can fetch very high returns in hilly regions of Uttarakhand if grown
in prior seasons to plain regions. Also, the mid-hill conditions of Uttarakhand are ideally suited
for off-season cultivation of Pea. Hence, selection of a suitable and appropriate variety and
season becomes very crucial in hilly regions for gaining high monetary returns and boosting
farmer’s income (Tiwari et al. 2014). The low productivity of Pea crop is attributed towards
several constraints like lack of quality and improved cultivars, lesser use of inputs and poor
extension services delivered to the farmers (Tiwari et al. 2021). By keeping all these factors
under consideration, several front-line demonstrations using improved cultivars of Pea crop
were carried out in the NICRA villages Dabri and Kaleth from year 2019-20 to 2021-22 to
enhance the productivity and economic returns per unit area in the farmer’s field.
Methodology
The present investigation was carried out in the NICRA villages i.e., Dabri and Kaleth under
Thauldhar block of district Tehri Garhwal during 2019-20 to 2021-22 under Technology
demonstration component (TDC) of project NICRA. The improved and high yielding varieties
of Pea (Arkel and PSM-3) were used by KVK, Tehri Garhwal, Uttarakhand for carrying out
front line demonstrations in fields of around 45 farmers in the NICRA villages to quantify the
technology gap and extension gap between demonstration and farmer’s practice. Frequent
visits as well as advisories were delivered to the farmers to implement the technology correctly.
The data pertaining to yield under demonstration and farmer’s practice was collected by
random crop harvesting methods and was analysed by using simple statistical tools. The
extension gap, technology gap and technology index were calculated using the following
