Abstract:
Analysis of factors affecting adoption of hybrid and open pollinated maize varieties had not been taken yet in
Nepal. Viewing this fact, this study was undertaken consisting of four purposively selected VDCs from two
central Terai districts, Bara and Sarlahi, of Nepal. A total of 110 maize growers including 86 adopters and 24
non adopters of hybrid maize varieties (adopters of open pollinated maize varieties) were interviewed with the
help of structured questionnaire. Results of t-test showed that adopters of hybrid maize varieties had
significantly larger farm size and, size of maize farm, were more experienced on maize farming, and used
significantly higher amount of chemical fertilizers but lower amount of organic manures than the non-adopters.
Further, more adopters used irrigation water, pesticides and hired labor than the non-adopters. The result
showed that a substantial proportion of land area grown to maize was cultivated to hybrid maize varieties with
an adoption rate of 81.9 % while the adoption rate for open pollinated varieties was estimated as 18.1%. The
results of the binary logistic regression analysis showed that adoption of hybrid maize was positively influenced
by farm size, irrigation availability, farmer’s attitude towards insect and disease tolerance characteristics of
hybrid maize, male headed family and credit availability in the surveyed area. However, farming experience on
maize was negatively associated with the adoption of hybrid maize varieties.

1. Introduction
Maize is the second most important cereal crop
after rice in terms of area and production and first
staple food crop for the hills in Nepal. It is grown in
875660 hectare of land with average yield of 2.11
t/ha. The proportion of maize area consists of 70.23%
in hills followed by 19.23% in Terai and 10.45% in
Mountain [1]. Almost all quantity of the maize
produced in the mid and high hills is utilized for
human consumption and a very little portion is fed to
animals. However, more than 80% Terai production is
being utilized for poultry and animal feeds and
remaining amount is used as industrial and human
consumption [2]. This indicates that maize is
emerging as a cash crop in Terai regions.
National Maize Research Programme (NMRP)
under Nepal Agricultural Research Programme
(NARC) has released 23 maize varieties, including 1
hybrid, over the last two decades. The potential
productivity of these varieties, except Arun-2, ranges
between 3 to 10.6 mt/ha [3]. Gaurav, the only one
hybrid maize released in Nepal in 2003, could not be
popularized in hybrid maize growing areas because of
the difficulty in its seed production particularly in
private sector. This situation has left no varietal
options for growing hybrid maize in Nepal and
farmers have to rely on seeds of multi-national hybrid
companies based mostly in India. Realizing this
situation, NMRP Rampur is making its effort towards
production of hybrid maize seed along with open
pollinated maize varieties and Rampur Hybrid-2 is in
releasing process.
Literature shows that hybrid maize was
introduced in Nepal long ago. About three decades
back, most farmers used to grow open pollinated
varieties, though a few farmers in the south used to
grow Indian hybrids [4]. The rate of adoption of
