International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities
during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Based on the survey, technical interventions have been taken up under different themes as
follows: NRM module: In-situ moisture conservation between paired rows of pigeon pea,
Contour cultivation, Mechanization: Sowing through Bullock drawn seed drill and weeding by
cycle weeder; Improved varieties: Finger millet (MR-1, GPU-28, ML-365), Groundnut (ICGV-
91114, KCG-6, K-6, K-1812) and Pigeonpea (BRG-5, BRG-2); Intercropping system: Finger
millet + Pigeonpea (8:2), Groundnut + Pigeonpea (8:2), Pigeonpea + Field bean (1:1) and
Cowpea + Field bean (1:1); Fodder module: Fodder maize (SA-tall), Fodder sorghum, Napier
multi-cut (CO-5); Perennial module: Melia dubia and tamarind has been introduced; Animal
module: Deworming 5-10 mg/kg of body weight (40ml /cow), Dry fodder: 5-7 kg/day/animal,
Green fodder: 25-30 kg/day/animal, Concentrates (Energy source: protein source: bran in
50:25:25 ratio): 4 kg/day/animal, Perethrin soap, Hi-min- Multi mineral nutrient mixture
(40g/animal/day)
Results
Among the different farmers category irrespective of different modules and farming situation
there is considerable improvement in system productivity (6567 kg/farming system) and
employment generation (343) in improved practices than the traditional farmers practice (4367
kg/farming system and 309, respectively) in marginal farmers category. Similarly, in small
farmer’s category higher system productivity (9321 kg/farming system) and employment
generation (351) was recorded in improved technological interventions than existing farmers
practices under rainfed farming situation. Further, under partially irrigated situation higher
system productivity (11909 kg/farming system and 14397 kg/farming system) and employment
generation (366- and 411-man days) was registered in improved practices both in marginal and
small farmer’s category, respectively (Mudalagiriyappa et al., 2017 and Ramachandrappa et
al., 2017). Further there was an increase in yield was noticed from 30 - 40 % and increase in
net return from 33 - 45 % both in rainfed and partially irrigated farming situation.
Conclusion
Integrated farming practices viz., in-situ moisture conservation between paired rows of pigeon
pea, sowing through bullock drawn seed drill and weeding by cycle weeder, using of improved
finger millet, groundnut and pigeonpea varieties and implementation of mineral mixture for
animals has enhanced the system productivity (kg/farming system) employment generation
(man days) and in improved practices than traditional practices followed by farmers. The
demonstrations also served as tools for up scaling the technologies to the surrounding farmers,
extension functionaries and policy makers
