Intercropping in the dryland areas ensures better utilization of all growth resources. The soils of
the drylands are not only thirsty but also hungry. So, to replenish nutrient pool, conservation of
soil and water and stability in yield, intercropping systems are necessary for the dryland
conditions/areas. The experiment consists of assessing the finger millet, pigeonpea and
groundnut along with suitable intercrops. The different intercropping yields were converted
into the finger millet equivalent yield.
Methodology
The experimental field study was conducted at the AICRP for dryland agriculture, Bengaluru
for three consecutive kharif seasons (2017-2019) to determine the profitable intercropping
system for the red soils in the Eastern Dry Zone of the Karnataka under the dryland condition.
In the Eastern Dry Zone of Karnataka, the most predominant intercropping systems are viz.,
Ragi, Pigeon pea, Groundnut, Maize and Castor based intercropping systems for Alfisols under
dryland situations. The cereal- legume interaction helps both the crops in their growth behavior
and inputs requirements leading to improvement and efficient utilization of resources like
nutrient, moisture, light and thereby increases productivity with enhancement of soil health by
taking advantages of biological nitrogen fixation by the legumes. The experiment comprised of
10treatments. viz, T 1: sole Finger millet, T 2: sole Pigeon pea, T 3: sole Groundnut, T 4: Finger
millet + pigeonpea (DS with BRG-5 variety), T5: Finger millet + pigeonpea (TP with BRG-5
variety), T6: Finger millet + akkadi, T7:Pigeonpea (BRG-1) + soybean (1:1), T8: Pigeonpea
(BRG -2) + cowpea (1:1), T 9: Pigeonpea (BRG-2) + field bean (1:1) and T 10: Groundnut
(ICGV-91114) + pigeonpea (BRG-5) (8:2). The crops were sown during kharif, finger millet
sown during month of July, pigeonpea in the month of May, cowpea, soyabean and fieldbean
in the month of May, groundnut in the month of June. The plot size of 3 m × 5m was adopted.
The varieties used were; finger millet (MR-6), pigeonpea (BRG-2 and BRG-5), groundnut
(variety ICGV 91114), Soyabean (Hardy), cowpea(IT 38956-1), fieldbean (HA-4).Akkadi crops
