Physical properties of chilli growing soils of Khammam district

Abstract

SummaryFifteen profiles from the chilli growing areas of the district were chosen for the study. Soil samples were collected horizon-wise and analysed for physical properties. The soil texture varied from sandy loam to clay loam in surface horizons and sandy clay loam to clay loam to clay in sub-surface horizons. Bulk density and particle density of soils varied from 1.37 to 1.66 and 2.44 to 2.60 Mg m -3 , respectively, the per cent aggregates greater than 0.25 mm and per cent aggregate stability ranged from 61.50 to 76.90, 48.40 to 64.60, respectively, hydraulic conductivity of the soils ranged from 0.08 cm hr -1 to 16.26 cm hr -1, the infiltration was moderately rapid to moderately slow and slow, the water retention at 33 and 1500 K Pa was low, the available water content ranged from 4.21 per cent to 13.62 per cent and the available water storage capacity (cm m -1 ) was low, medium to high.

Effect of Continuous Irrigation on Soil Texture, Bulk Density and Saturated Hydraulic Conductivity of Some Soils in Hirakud Command Area of Odisha, India

“…This result was in agreement with the findings of Saikumar and Rao (2016) and Halder et al, (2015). Use of implements for cultivation of crop provide favourable situation for reduction in bulk density and more aeration.…”

“…On the other hand the organic matter content was less in the sub surface layer and more compaction in the subsurface layer which facilitates the reduction in hydraulic conductivity. This result corroborated with the result of Saikumar and Rao (2016). The mean saturated hydraulic conductivity of surface soils of irrigated area was lower (17.2 cm/h) than that of unirrigated area (18.0 cm/h).…”
