International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities
during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
six herbal medicinal plants crops. The data was analyzed by online OPSTAT software and LSD
(least significant difference) was calculated at 5 per cent level of significance (Snedecor and
Cochran 1967).
Results
There was a significant variation in bulk density of soil at both depths. The lowest bulk density
was recorded in mentha and brahmi intercropped block (T4 and T2) which was on par with
turmeric, lemongrass and stevia intercropped treatments (T4, T3 and T5). The sole treatments (T7)
had higher bulk density values among all other treatments.
Soil porosity varied from 47.80 to 49.81 % and 46.93 to 48.74 % from both depths 0-15 and 15-
30cm, respectively. While the intercropping of brahmi (49.81%) under guava-based system had
significantly higher porosity which was very close to mentha intercropped blocks (49.56%) and
at par with treatments T3, T5 and T6 and lowest value found in T7 (guava sole).
The availability of N, P and K of soil at depth 0-15cm, were significantly higher under guavabased
cropping systems in all the treatments than the guava sole (Fig.). Significantly maximum
available N was recorded in T4, which was followed by T2 and the lowest available nitrogen was
found in the T7 treatment.
