Abstract
The present experiment was conducted on “Studies on growth, yield and nutrient
uptake of intercrops in alleys of Hoary pea (Tephrosia candida DC) at Ranchi” laid out
in 2020 in agroforestry field at Ranchi Veterinary College Farm campus at Birsa
Agricultural University, Ranchi. Keeping in view of the fact, the present investigation is
being proposed with the objectives: 1. To study the growth and yield of intercrops in
alleys of Tephrosia. 2. To estimate the nutrient uptake by different crops and change in
physico chemical properties of soil. 3. To assess the economics of the practices.
The plants were planted in the year 2018 at spacing 3mx3m.This experiment was
laid for the purpose to understand the best combination for growth, yield and nutrient
uptake of Tephrosia based intercropping with Linseed, Field Pea, Lentil, Mustard and
Chickpea in Rabi in Randomized Block Design. Each treatment was replicated four
times in the experimental plot. Soil samples were collected before sowing of intercrops
and after harvest of intercrops for chemical analysis.
In the present study, the different growth parameters of agricultural crop such as
Crop height (cm), Number of branches per plant, Number of Pod / Siliqua / Capsule per
branch, Number of seeds per Pod / Siliqua / Capsule, Seed test weight (g), Stover yield
(kg ha-1) were taken during standing crops and yield attributing character such as Grain
yield (qha-1), Biological yield (qha-1), Harvest index (%) were taken at the time of
harvesting. The analysis of soil data such as Soil pH, Nitrogen, Phosphorus, Potassium
and Organic carbon were taken in the soil laboratory using standard method.
The present findings indicates that among agricultural crops maximum height
was found in 138.67cm in T4 (Tephrosia + Mustard) followed by 64.59cm in T2
(Tephrosia + Field pea) and minimum height was found in 42.31cm in T3 (Tephrosia +
Lentil). The maximum no. of branches per plants was found in 23.46 in T5 (Tephrosia +
Mustard) followed by 15.85 in T2 (Tephrosia + Field pea) whereas maximum no. of
pods/capsule/siliqua per plant was found in 96.75 in T4 (Tephrosia + Mustard) followed
by 55.78 in T1(Tephrosia+Linseed).
The seed test weight was found in 136.25 gm in T5(Tephrosia+Mustard) followed
by 95.50 gm in T2(Tephrosia+Field pea) and least was found in 3.04 gm in T4 (Tephrosia
+ Mustard) whereas stover yield (q/ha) was found in 40.00 in T5 (Tephrosia + Mustard)
followed by 37.05 in T2(Tephrosia+Field pea) and least was found in 25.31 in T1
(Tephrosia + Linseed). Significant effect of Tephrosia candida on stover yield was of
agricultural crops was found. The increasing order of stover yield was found as
T1>T4>T3>T2>T5.
Agricultural crops yield (q/ha) was found in 18.38 in T5(Tephrosia+Chickpea)
followed by 17.28 in T2(Tephrosia+Field pea) whereas harvest index (%) was found in
36.87% in T1(Tephrosia+Linseed) followed by 36.73% in T4(Tephrosia+Mustard) and
minimum was found in 31.48% in T5(Tephrosia+Chickpea). The increasing order of
height found as T5>T3>T2>T4>T1.
Soil status after intercropping, the maximum OC% was found in 0.439 in T1
(Tephrosia + Linseed) followed by 0.386 in T2 (Tephrosia+Field pea). The maximum
Nitrogen available was found to be 270.673h in T1(Tephrosia+Linseed) followed by
238.38h in T2 (Tephrosia + Field pea) and minimum was found in 207.013h in T4
(Tephrosia + Mustard). The maximum potassium available was found in 16.225h in T4
(Tephrosia + Mustard) followed by 15.233h in T3(Tephrosia+Lentil) and minimum was
found in 11.55h in T1(Tephrosia+Linseed). The maximum potassium available after
intercropping was found in 147.625h in T1(Tephrosia+Linseed) followed by 146.55h in
T5 (Tephrosia + Chickpea) and minimum was found in 139.658h in T4 (Tephrosia +
Mustard).
