Description A field experiment with 18 treatments comprising of 2 land configurations
(L1- flat bed and L2- raised bed), 3 crops (C1 - wheat, C2 - castor and C3- sorghum)
and three organics (A0- control, A1-farm yard manure and A2 - pressmud) in SPD with
four replications was conducted at Soil and Water Management Research Farm,
Navsari Agricultural University, during the rabi season of 2003-04.
The results revealed that all the biometric parameters of different crops were
numerically higher in raised bed planting as compared to flat bed. The raised bed
planting increased the seed/grain yield of wheat, castor and sorghum by 7, 14 and 9
per cent, respectively over flat bed sowing. Also, application of organics i.e., PM
numerically increased the biometric parameters and this ultimately resulted in higher
seed/grain yield of crops. The increase in seed/grain yield of wheat, castor and
sorghum was of the order of 28, 25 and 18 per cent, respectively with the treatment
receiving PM over its no application. In general, uptake of major as well as
micronutrients were affected significantly due to C, L and A. The uptake of major as
well as micronutrients were significantly higher by sorghum (C3) crop, except Cu
removal which was significantly higher by wheat (C1). The raised bed sowing
recorded significantly higher uptake of all major as well as micronutrients. An
increase in uptake of N, P and K with raised bed was 12, 13 and 12 per cent,
respectively. Similarly, the uptake of Fe, Mn, Zn and Cu by crops was enhanced
by 17, 13, 17 and 21 per cent, respectively. Among the organics, application of
PM significantly increased the uptake of all major as well as micronutrients. The
magnitude of increase in uptake of N, P, K with PM was 25, 11 and 7 per cent as
compared to control. With respect to uptake of Fe, Mn, Zn and Cu the increase
was of 21, 21, 28 and 21 per cent, respectively over control.
Coarser and finer fractions of water stable aggregates were
significantly influenced only due to FYM additions in surface soil and the
extent of increase was by 9 per cent as compared to control. Bulk density was
affected significantly due to L and A factors. The BD was decreased by 4 per
cent due to raised bed and 6 per cent due to application of FYM as compared
to control. Infiltration rate was also affected significantly due to all three
factors i.e., C, L and A. Among the crops, castor registered significantly
higher infiltration rate (9.5 mm/hr) as compared to other two crops. Similarly,
the raised bed configuration and FYM application could improve IR of soil by
8 and 13 per cent, respectively.
Raised bed configuration could decrease the EC of surface soil by 8
and 14 per cent at 60 DAS and at harvest, respectively. Amending the soil
with PM also decreased pH and EC values of soil. The extent of decrease
in pH was 1.27 and 1.75 per cent at 60 DAS and harvest, respectively.
Whereas, in case of soluble salts, this decrease was 10 and 20 per cent less
than control. Organic carbon content in soil increased due to PM
and
FYM application by 3 and 7 per cent at 60 DAS and 9 and 16 per cent after harvest of
crops.
The availability of N, P and K was tended to increase significantly in surface
soil after harvest of crop only due to PM application. The increase in available N, P
and K content in soil after harvest of crop was 3, 20 and 23 per cent, respectively.
Similarly, the availability of Fe, Mn, Zn and Cu was also increased significantly with
raised bed configuration. At 60 DAS, this increase was ranging from 7 to 10 per cent.
An application of PM also improved the availability of micronutrients significantly
and the extent of increase was by 13, 10, 5 and 5 per cent in case of Fe, Mn, Zn and
Cu, respectively in surface soil at 60 DAS.
Raised bed configuration significantly improved the bacterial population (8 %)
after harvest of crops over flat bed. The beneficial effect of FYM application was also
evident on bacterial and fungal population, as the population was increased by 6 and
34 per cent, respectively over no application.
Considering the equivalent yield, gross and net returns, performance of castor
was found to be more remunerative followed by sorghum. Wheat cultivation after
kharif paddy is not economical. The extent of monetory benefits tended to improve
with raised bed sowing and application of either PM or FYM.
