International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Total 229 lakhs liters of water is harvested that resulted in rise of ground water table upto 8.9
meters. This in turn helped to increase area under protective irrigation in kharif (26.60
hectares), rabi (19.80 hectares) and summer (11.20 hectares) seasons.
In this protective irrigated area various crops are cultivated. Totally in four years period,
different crops like maize, rabi sorghum and bengalgram crops are cultivated in 101.40
hectares area in kharif and 72.60 hectares area in rabi season. Protective irrigation provided
from the recharged bore well resulted in increase in yield and net returns of different crops.
There was a significant increase in yield of various crops from 34.08 to 54.94 percent and net
returns of Rs.5,116/- to Rs.16,679/- per hectare. An additional return of Rs.19.96 lakhs returns
was gained by the farmers during 2018 to 2021. Hence, the recharging of bore wells is very
important in the rainfed area to enhance the economic status of the farmers even during climatic
variations.

A field experiment was conducted during rabi season 2016-17 to 2019-2020 in Inceptisol to
explore the possibilities rainwater harvesting and recycling for the purpose of raising rabi crops
to enhance the crop productivity and water productivity of Nadi system in semi-arid areas under
All India Coordinated Research Development Project at Dryland Farming Research Station
(Maharana Pratap University of Agriculture and Technology, Udaipur), Arjia, Bhilwara
(Latitude 24”20’N and 74”40’ Longitude and 432 meter above sea level), Rajasthan. The site
soils of experimental field were sandy clay loam in texture having pH 8.11, organic carbon
0.42%, E.C. 0.44 dSm-1, bulk density1.51 gm cc -1 , the available N, P2O5 and K2O in soils were
243.56,21.52 and 416.27 kg ha -1 , respectively. The field capacity and permanent wilting point
moisture of surface soil layer was 21.4 and 9.2% on weight basis, respectively. There were
three main plot treatments of crops as C 1-Lentil, C 2-Chickpea and C 3-Mustard and three in sub
treatment of irrigation methods such as I0- Control (conserved moisture), I1- One irrigation at
45 DAS and I 2- Two irrigation at 45 & 60 DAS. These treatments were laid out in Split plot
design with three replications. Among the different crops, lentil crop gave 162% higher mean
mustard seed equivalent yield (1765 kg ha -1 ) in comparison to linseed (672 kg ha -1 ). However,
application of supplemental irrigation at 45 DAS and 45 & 60 DAS was increased mean
