Abstract
The research entitled with “Study on growth and yield of tree with intercrops
under Teak based Agroforestry system at Ranchi, Jharkhand” was conducted at Rice
farm (W section), B.A.U kanke, Ranchi. The experiment was laid out to find out the best
combination for growth, yield and economic feasibility of Chickpea, Lentil, Linseed and
Safflower crops in Rabi 2018 - 2019. Consisting of methods of sowing and time of
sowing under open and shaded conditions in all possible combinations were tested in
RBD with three replications with following objectives: 1. To study the growth and yield
of field crops with Teak. 2. To analyse the physico-chemical properties of soil under this
system. 3. To study the economics of the system.
The maximum increment in height of Teak (Tectona grandis) was found in T2
(Teak + Chickpea) 0.08 m followed by T1 (Teak + Lentil), T3 (Teak + Linseed) 0.06 m
and T4 (Teak + Safflower) 0.06 m least was found in T5 (sole Teak) 0.05 m. The
maximum increment in diameter of Teak (Tectona grandis) was found in T2 (Teak +
Chickpea) 0.13 cm followed by T1 (Teak + Lentil) 0.12 cm, T3 (Teak + Linseed) 0.11
cm, T4 (Teak + Safflower) 0.10 cm and least in T5 (sole Teak) 0.08 cm. The maximum
increment in basal area of Teak (Tectona grandis) was found in T1 (Teak + Lentil) and
T2 (Teak + Chickpea) 0.00027 m2 which is more than T4 (Teak + Safflower) 0.00026 m2
followed by T3 (Teak + Linseed) 0.00025 m2 and least in T5 (sole Teak) 0.00025 m2. The
maximum increment in volume of Teak (Tectona grandis) was found in T2 (Teak +
Chickpea) 0.000507 m3 followed by T1 (Teak + Lentil) 0.000484 m3 > T3 (Teak +
Linseed) 0.000466 m3 > T4 (Teak + Safflower) 0.000438 m3 and least in T5 (sole Teak)
0.000393 m3.
Grain yield of Lentil was found maximum in T7 Sole Lentil (9.36 qha-1) and
minimum in T1 Teak + Lentil (6.25 qha-1). The highest grain yield of Chickpea was
found in T6 Sole Chickpea (9.32 qha-1) and minimum in T2 Teak + Chickpea (6.12 qha-1).
The grain yield of Linseed was found highest in T9 Sole Linseed (8.68 qha-1) and lowest
in T3 Teak + Linseed (6.38 qha-1). The grain yield of Safflower was found maximum in
T8 Sole Safflower (5.81 qha-1) and minimum in T4 Teak + Safflower (3.9 qha-1).
Maximum bulk density was found in T9 sole Linseed (1.36 gcm-3) followed by T8
sole Safflower (1.35 gcm-3), T7 sole Lentil (1.33 gcm-3), T6 sole Chickpea (1.32 gcm-3),
T3 Teak + Linseed (1.24 gcm-3). It was also observed that T1 Teak + Lentil (1.23 gcm-3),
T2 Teak + Chickpea (1.23 gcm-3) and T4 Teak + Safflower (1.23 gcm-3) shows equal bulk
density and least were found in T5 sole Teak (1.13 gcm-3). pH of the treatment plots was
significantly varying from 4.34 to 4.65. Before intercropping pH were 4.29. After
intercropping the maximum pH was found in T5 sole Teak (4.65) followed by T1 Teak +
Lentil (4.48), T2 Teak + Chickpea (4.45), T6 sole Chickpea(4.43), T7 sole Lentil (4.41),
T4 Teak + Safflower (4.39), T3 Teak + Linseed (4.38), T8 sole Safflower (4.37) and least
was found in T9 sole Linseed (4.34). Organic carbon content before intercropping was
found 0.46% and the organic carbon content under intercropped condition found better
as compared to the sole cropping of the treatments plots and after harvesting of the
intercrops the organic carbon content varies from 0.39% to 0.69%. The maximum
organic carbon found in T1 Teak + Lentil (0.69%) which is at par with T5 sole Teak
(0.65%), T4 Teak + Safflower (0.63%), T2 Teak + Chickpea (0.62%) followed by T3
Teak + Linseed (0.60%), T6 sole Chickpea (0.44%), T9 sole Linseed (0.42%), T7 sole
Lentil (0.40%) and least was found in T8 sole Safflower (0.39%).
Maximum net return gained by T1 Teak + Lentil (` 36038.61 ha-1), followed by T2
Teak + Chickpea (` 33999.34 ha-1), and T3 Teak + Linseed (` 32069.5 ha-1). Benefit cost
ratio was maximum in T5 sole Teak (3.698:1) followed by T7 sole Lentil (2.962:1), T1
Teak + Lentil (2.767:1), T3 Teak + Linseed (2.562), T2 Teak + Chickpea (2.411:1), T9
sole Linseed (2.402:1), T6 sole Chickpea (2.398:1), T4 Teak + Safflower (2.292:1) and
minimum was found in T8 Sole Safflower (2.144:1).
