SPRINKLER IRRIGATION, CHICKPEA (Cicer arietinum L.)
 
Description A field experiment was conducted on sandy clay soils of the
Agricultural College Farm, Bapatla, entitled “Effect of moisture conservation
methods and sprinkler irrigation on growth and yield of chickpea (Cicer
arietinum L.)” during rabi, 2008-09. The treatments consisted of three moisture
conservation methods (L1- flat sowing, L2- broadbed-and-furrow (BBF) and L3-
ridge-and-furrow (RF) systems) assigned to horizontal strips and four sprinkler
irrigation systems (I0 - no irrigation, I1 - one sprinkler irrigation at branching, I2
- one Sprinkler irrigation at pod initiation and I3-two sprinkler irrigations each
at branching and at pod initiation stages) as vertical strips arranged in a strip
plot design and were replicated thrice
The tallest plants and more number of branches per plant at 30 DAS
were recorded with crop grown on broadbed-and-furrows system, over ridge-
and-furrow and flat systems. Flat bed land configuration proved significantly
inferior over other two land configurations in increasing growth parameters of
chickpea. The maximum drymatter accumulated under broadbed-and-furrow
system with two sprinkler irrigations was on a par with ridge-and-furrow
system with one sprinkler irrigation.
Irrigation at branching and pod initiation stages (I3) resulted in higher
plant height, drymatter and number of days to 50% flowering over one-time
irrigation either at branching or pod initiation stages. However, the difference
in drymatter production between one-time irrigation at branching and at pod
initiation stages was not significant.
Chickpea sown on broadbed-and-furrow system recorded significantly
higher number of pods per plant, test weight, seed yield and haulm yield over
that of other two land configurations. However, the number of seeds per pod
recorded with broadbed-and-furrow system was on a par with ridge-and-furrow
system.
Application of two sprinkler irrigations each at branching and pod
development stages resulted in significantly higher number of pods per plant,
seeds per pod and ultimately yield over one-time irrigation at branching (I1) or
at pod development (I2) and no irrigation (I0). Irrigation at branching (I1) found
significantly superior to irrigation at pod development (I2) in increasing number
of pods per plant, test weight and finally the seed and haulm yields. However,
the number of seeds per pod of chickpea recorded with one-time irrigation
either at branching or at pod initiation stages was not significant.
The highest consumptive use of water recorded with broadbed-and-
furrow system was on a par with that of ridge-and-furrow system. However, the
water use efficiency recorded with BBF was significantly higher than that of
the other two moisture conservation practices. Application of two irrigations
resulted in significantly more consumptive use and moisture use rate than with
one irrigation. A higher return per rupee invested was realized from BBF
system with two irrigations (L2I3).
Overall, the results showed that sowing on broadbed-and-furrow system
found suitable for higher productivity of chickpea over ridge-and-furrow and
flat bed systems. Two sprinkler irrigations each at branching and at pod
initiation stages were found optimum as evidenced by higher drymatter
production and seed yield.
