Abstract
Bamboos based agroforestry can play an important role in enhancing
productivity, sustainability and resource conservation. Under agroforestry system,
bamboos are also benefited due to sharing of resources like irrigation, fertilizers,
weeding, etc. with intercrops; as a result the quantity and quality of bamboos are
expected to be much higher as compared with monoculture and unmanaged plantations.
Incorporation of medicinal plants with Agroforestry System will help to conserve them
and restore the biodiversity and in turn it will generate not only income but also improve
livelihood status of rural and tribal people. Keeping these important aspects in view, a
systematic research trial was undertaken on Bamboo, intercrops with Kalmegh,
Ashwagandha and Sadabahar namely “Studies on Growth and Yield of Medicinal
Plants under Bamboo based Agroforestry System” at Agroforestry Research Field,
B.A.U. Ranchi in the year 2020-21 with the following objectives: (a) To study the
growth and yield potential of Andrographis paniculata, Withania somnifera,
Catharanthus roseus under Bamboo-based Agroforestry system b)To evaluate soil
fertility status after harvest of Medicinal plants c)To study the comparative economics of
different medicinal plants under bamboo based Agroforestry system.
Research was laid out in Randomized Block Design with 7 treatments either
solely or in combination, replicated in thrice. Experimental material consisted of
Bambusa nutans, Kalmegh variety Anand Kalmegh1, Ashwagandha variety Gujrat
Ashwagandha and Sadabahar variety Gujrat local. Parameters studied in Bambusa nutans
were survival of culms, culm height, number of culms in clump, diameter at collar
region, clump spread, length of lowest internode, diameter of lowest internode, number
of internode, length of 5th internode, diameter of 5th internodes and leaf area index.
Parameters studied in medicinal plants were plant height, number of primary
branches/plant, number of capsules/plant, number of seeds/capsule, dry weight/plant,
seed yield/plant and leaf area index. Data on different parameters of medicinal plant was
collected as per NBPGR guidelines and the replicated data on different parameters was
subjected to Analysis of standard error of mean, coefficient of variation and critical
difference.
The growth performance of the Bambusa nutans was varies from treatment to
treatment under agroforestry system. The maximum mean increment in culm height
(2.84 m) was recorded under T4 Sole Bamboo which was at par with T3 Bambusa nutans
intercropped with Catharanthus roseus (2.81m) and least was found under T2 Bambusa
nutans intercropped with Withania somnifera (2.25m). The maximum mean increment in
number of culm was recorded under the treatment T3Bambusa nutans intercropped with
Catharanthus roseus and T4 Sole Bamboo (4.08) followed by T2 Bambusa nutans
intercropped with Withania somnifera (3.92) and least was found under treatment T1
Bambusa nutans intercropped with Andrographis paniculata (3.83). The maximum mean
increment in diameter of lowest internode was found under the treatment T3 Bambusa
nutans intercropped with Catharanthus roseus (0.53 cm) and least was found under
treatment T4 Sole Bamboo (0.41 cm). The maximum mean increment in number of
internode was recorded under T4 Sole Bamboo (18.08) and minimum was in T1 Bambusa
nutans intercropped with Andrographis paniculata (16.08). Highest mean increment of
diameter of 5th internode was seen under treatment T4 Sole Bamboo (0.46 cm) where as
least was found under treatment T2 Bambusa nutans intercropped with Withania
somnifera (0.29 cm). Maximum mean increment in culm spread was found under the
treatment T4 Sole Bamboo (49.37 m) whereas minimum was found under the treatment
T1 Bambusa nutans intercropped with Andrographis paniculata (1.31 m).Maximum
mean increment in diameter at collar region was found in T1, T2, T3 (0.45 cm) while
minimum was found in treatment T4 Sole Bamboo (0.39 cm).Highest LAI was found in
treatment T1 Bambusa nutans intercropped with Andrographis paniculata (1.31) whereas
least in T2 Bambusa nutans intercropped with Withania somnifera (1.17).
Intercrops height, Leaf Area Index, Dry Weight Crops per Plant and Seed Yield
per Plant was found maximum in T7 Sole Catharanthus roseus 52.93 cm, 2.46, 59.76 g,
8.07 g respectively. Least Intercrops height, Leaf Area Index was found under T1
Bambusa nutans intercropped with Andrographis paniculata 42.48 cm, 0.99 while Dry
Weight Crops per Plant and Seed Yield per Plant was found minimum in T2 Bambusa
nutans intercropped with Withania somnifera 8.19 g and 2.61 g respectively. Maximum
number of primary branches per plant was found under treatment T5 Sole Andrographis
paniculata 12.33 which was at par with T1 Bambusa nutans intercropped with
Andrographis paniculata 11.67 and minimum was found with T2 Bambusa nutans
intercropped with Withania somnifera 3.53. Highest number of capsules per plant was
found under treatment T5 Sole Andrographis paniculata 219.77 and least was found
under T3 Bambusa nutans intercropped with Catharanthus roseus 49.367.
After harvesting intercrops highest pH was found in case of treatment T7 Sole
Catharanthus roseus (5.37) and minimum was found under T6 Sole Withania somnifera
(4.00). After harvesting highest O.C % value observed under T5 Sole Andrographis
paniculata (0.52 %) and least under T2 Bambusa nutans + Withania somnifera (0.40 %).
The available phosphorus of soil after intercrops was found maximum under T5 Sole
Andrographis paniculata (15.91 kg/ha) and least under T4 sole Bambusa nutans (13.14
kg/ha). The available potassium of soil after intercrops was found maximum under T5
sole Andrographis paniculata (250.26 kg/ha) and least under T2 Bambusa nutans +
Withania somniferous (143.26 kg/ha). The highest B:C ratio was found in T7 sole
Catharanthus roseus. The highest B:C ratio was found in T7 Sole Catharanthus roseus.
