Expt.1. Effect of intercropping chickpea with
sunflower under different row and spacing arrangements
Abstract
The experiment was
conducted to find out the effect of intercropping chickpea with sunflower under
different row and spacing arrangements at the experimental field of Agronomy
Department of of Sher-e-Bngla Agricultural University, Dhaka-1207, Bangladesh
during the period from Nov 2008 to March 2009. Seeds of sunflower variety DS-1
(Kironi) and Chickpea variety BARI Chola-5 used as a test crop for the study.
The experiment consisted of nine row arrangement combinations of sunflower and
chickpea plus sole treatment of both the crops. The row arrangement comprised
combination of four planting patterns: row to row distance between two paired
row of maize (30-50 cm); gap between two adjacent maize paired rows (70 – 100
cm); number of rows of chickpea (1-4) planted in the gap between two adjacent
paired rows of maize; and row to row distance of chickpea (20-40 cm). Results
revealed that the maximum soil moisture (30-35%), LER (1.76),
equivalent yield of sunflower (3.81 t ha-1), equivalent yield of chickpea
(4.49 t ha-1) , combined yield of sunflower and chickpea (4.08 t ha-1)
and was recorded when two rows of chickpea were sown 40 cm apart in 70 cm
gap of sunflower paired rows of 30 cm apart which was significantly higher than
those of both the sole crop maize and chickpea.
Expt. 2: Performance Of maize mungbean
intercropping grown under different plantion geometry
Abstract:
A field experiment was
carried out at Sher-e-Bangla Agricultural University farm to study the effect
of intercropping summer mungbean with maize on the fodder and grain yield
productivity under different planting geometry. There were fourteen treatments comprising
different combinations of row and space arrangements (maize paired row planted
at 25-37.5 cm apart leaving 75-112.5 cm space between two adjacent maize paired
row, 2-4 rows of mungbean planted using 17-30 cm row to row distance between
two adjacent maize paired rows). Results showed that both the sole maize
and mungbean gave the highest values in most of the plant parameters studied.
Among the intercropping treatments with maize paired rows planed 25 cm-apart
leaving 85 cm space between adjacent paired rows accommodating 2-3 rows of
mungbean planted 25 cm apart gave comparatively higher values of yield and
yield parameters of maize. But the sole mungbean showed significantly the
highest values of fodder and grain yield and also those of yield attributes.
The highest net return, maize equivalent yield, LER and BCR were Tk. 69615,
7307.67 Kg/ha, 1d.43 and 2.74 respectively with the same treatment.
