International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
that, the Banana variety Kaveri saba was performed well in Kurumbalur hamlets of Perambalur
district also given the high yield under less irrigated condition during rabi season (2020-22).
An average yield of 468.56 q ha -1 was recorded in front line demonstration and in farmer
practices it was just 392.23 q ha -1 . Thus, the average technology gap, extension gap and
technology index of 121.44, 76.33 and 20.50 percent were observed between demonstration
and farmer practices. The average yield of banana increased by 20.58 percent over farmers'
practices. Moreover, farmers inferred that the fruits have high market preference and fetching
premium price owing to its good keeping quality with green life of 7-8 days.

Cluster bean (Cyamopsis tetragonoloba (L.) is popularly known as guar, chavli kayi, guari,
khutti etc in local languages of southern India. Dry regions of West Africa as well as India are
considered as centres of origin of cluster bean though diverse opinion on exact origin of cluster
bean is still prevails. It is characterized as a short-day erect or bushy annual plant (Purseglove,
1981). It is a drought tolerant, warm season legume crop with deep and well-developed root
system, cultivated mainly as rainfed crop in arid and semi-arid regions during rainy (kharif)
season for vegetable, galactomannan gum, forage and green manure. Cluster bean is mainly
cultivated for food, feed and fodder (Reddy et al., 2017). North Eastern part of Karnataka
experiences frequent and intermittent droughts coupled with high temperature. The farmers are
following the traditional cropping system of Rabi sorghum-sunflower production system. The
market price of Rabi sorghum is very low and that of sunflower is very much fluctuating and
often gets infected with powdery mildew. The variation in market price results in loss to the
farmers and even they are unable to meet out the cost of cultivation. Rabi sorghum is the main
food crop of the Northern Karnataka. Hence farmers are growing rabi sorghum for food
requirement and fodder to their livestock. Apart from growing Rabi sorghum, there is a scope
for introduction of cluster bean (gum type) so that the farmers can get an additional income
apart from food grains. Keeping the above in mind the present investigation was taken up to
evaluate and identify the suitable genotype and to standardize the suitable planting geometry.
