International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Pradesh, the crop is cultivated in 6.8 lakhs hectares during kharif with an average production
and productivity of 3.3 lakh tonnes and 484 kg ha -1 , respectively. Y.S.R Kadapa district is one
of the potential districts for groundnut in Andhra Pradesh where the groundnut area is decreased
from 44,179 ha during 2012-13to 25,315 ha during 2017-18. There was also wide fluctuation
in the groundnut productivity of the district i.e between 252 to 1560 kg ha -1 during the last seven
years.
In order to address the production constraints and achieve the sustainable yields in groundnut,
along with the objective of adopting Best Management Practices (BMP), Cluster Frontline
Demonstrations (CFLDs) in groundnut were demonstrated among the farmers’ fields by the
scientists of KrishiVigyan Kendra, Utukur under the scheme of National Food Security Mission
(NFSM), Ministry of Agriculture, GoI through ICAR-ATARI-Zone-Vin selective mandals of
YSR Kadapa district.
Methodology
CFLDs in groundnut were organized by KVK, Utukur during kharif season in rainfed alfisols
of Lakkireddipalli and Chinnamandem mandals of Y.S.R. Kadapa district (at present
Annamayya district) of Andhra Pradesh during 2017-18 and 2018-19, respectively. An area of
20 ha in42farm holding/demonstration sites were covered. The actual rainfall received by
Lakkireddipalli and Chinnamandem mandals during South West monsoon period is 301.0 mm
and 318.5 mm as against normal rainfall of 404.0 mm during the study years. Under this
programme, each demonstration site implemented the BMP’s recommended by ANGRAU like
1) Improved seed: groundnut var .dharani, 2) Application of biofertilizers viz. Rhizobium, PSB
and KSB@ 5 kg ha -1 3)Soil test based fertilizer recommendation,4) Application of Gypsum @
500 kg ha -1 at flowering stage 5) Integrated Pest Management (IPM): Seed treatment with
Imidachloprid 600 FS @ 2 ml + 4 L water per kg seed, border cropping with Bajra/Jowar,
spraying of neem oil (1500 ppm) at 20-30 DAS, erection of pheromone traps @ 20 no’s ha -1 ,
erection of bird perches @ 20 no’s ha -1 and judicious use of pesticides 6) Implementation of
Resource Conservation Technologies (RCT’s)/tools: Sub soiling with sub soiler at an interval
of 1.0 m and compartmental bunding with size of 40 m 2 (8 m x 5m) for insitu rain water
conservation and using seed to seed mechanization7) Using drip/sprinkler system/rain guns for
life saving irrigation during dry spells at critical stages8) Spraying of 2 per cent Urea to mitigate
dry spell were demonstrated in farmer’s fields (demo plots) against farmer’s
practice(check)which include:(Seed from the local vendors/home grown with low yield
potential and susceptibility to diseases (eg. K-6/mixtures), application of complex fertilizers,
no adoption of resource conserving techniques/insitu rain water conservation practices, no
drought management and IPM practices). Under demonstration plot, improved groundnut var.
dharani and bio-fertilizers were given to the farmers by the KVK.
