A field experiment was conducted to evaluate the crop covers for their impact on
soil and nutrient losses through runoff and status of soil organic carbon (SOC) and
other structural parameters of vertisol. Seven treatments consisted of three sole
crop covers ., soybean, maize and pigeon pea and three intercrop covers namely
soybean+ maize (1:1), soybean + pigeon pea (2:1) and maize + pigeon pea (1:1)
along with one cultivated fallow (control). Results obtained over two years of
experimentation revealed that the highest runoff (208 mm) and soil loss (2.87 t ha )
was recorded higher under cultivated fallow as compared to sole as well as
intercrops in both the years. Among the crop cover treatments, the runoff and soil
loss was significantly higher under sole pigeon pea (177 mm and 2.15 t ha ),
respectively followed by sole maize (167 mm and 1.99 t ha ), maize + pigeon pea
(140 mm and 1.60 t ha ), soybean + maize (135 mm and 1.48 t ha ), soybean +
pigeon pea (132 mm and 1.34 t ha ) intercrops and lowest was under soybean sole
crop (132 mm and 1.48 t ha ). The losses of soil organic carbon (23.55 kg ha ) and
total NPK (5.59, 0.65, 23.91 kg ha ) were the highest under cultivated fallow over
sole and intercrops. The losses of SOC and total NPK were lower under sole
soybean and its intercrops as compared to sole crops of maize and pigeon pea.
System productivity in term of soybean equivalent yield (SEY) was significantly
higher under maize + pigeon pea (5164 kg ha ) and soybean + maize (3193 kg ha )
as compared to soybean yield. Therefore, the combinations of maize + pigeon pea
(1:1) as an intercrop is the best options in reducing runoff, soil nutrient losses and
sustaining crop productivity of systemNot Available
