International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Keeping in view the conditions above, Krishi Vigyan Kendra, Kullu at Bajaura (HP)
demonstrated the short-duration and drought-resistant varieties intending to mitigate the
impact of climatic aberrations.
Methodology
Krishi Vigyan Kendra Kullu laid 362 No. of frontline demonstrations (FLDs) on wheat in the
NICRA villages viz. Choyal and Gadouri. These villages are located at 31°50’40” to 57°0’0”
N latitude and 77° 05’20” to 77°10’40” E longitude at an elevation of 1,100-1,234 m a.m.s.l.
The study involved the incorporation of the complete Improved Package (IP) which includes
short duration and drought-resistant recommended varieties of the CSKHPKV Palampur,
recommended fertilizer, and pesticide in comparison to the farmer's practice (FP). These
varieties were tested in the rainfed conditions that prevailed in these villages. Based on data
collected from the FLDs, the results were compiled and inferences were drawn.
Results
The data reflects that with the adoption of an improved package (IP) on wheat, the grain yield
was invariably higher (2910 to 3650 kg ha -1 ) over the farmer's practice (FP) that ranges from
2420 to 2840 kg ha -1 from 2015-16 to 2018-19 (Table 1) which may be ascribed to the
adoption of recommended agro-technologies during the study period. With the adoption of IP
in wheat, the yield levels could be raised by 15.61 to 28.93 % over the FP. The technology
gap recorded ranges from 350 to 1240 kg ha -1 during the years of investigation. The highest
technological gap was obtained during rabi 2018-19 in the variety HPW-349 (1240 kg ha -1 )
followed by 1090 kg ha -1 during rabi 2015-16 while the lowest gap was observed during rabi
2018-19 (350 kg ha -1 ). This may be attributed to the lack of irrigation facilities and improper
distribution of rainfall (Kumar et. al. 2015). The Extension gap ranges from 420 to 810 kg ha -
1
with the maximum during 2018-19 (810 kg ha -1 ) which indicates that there is a strong need
to be aware and motivate the farmers to minimize the extension gap. The technology index
indicates the feasibility of the evolved technology in the farmers’ fields under existing agroclimatic
variations which varies from 9.59 to 41.89 %. Lower the value of the technology
index and higher the feasibility of improved technology (Choudary, 2013).
