Effect of spatial arrangement of chickpea (Cicer arietinum L.) and linseed (Linum usitatissimum L.) on their yields, net returns and pod damage of chickpea

A field experiments was conducted during three consecutive rabi seasons of 2015–16, 2016–17 and 2017–18 to study the effect, net of spatial arrangements of chickpea and linseed on yield, net returns and LER; and to find out the most optimum chickpea + linseed row ratio. The results revealed that maximum pooled chickpea equivalent yield (20.72 q/ha), mean gross, net and B: C ratio ( 109934, 82404 and 3.40) and LER (1.17) were recorded under chickpea + linseed in 5: 1 row ratio. This was closely followed by 5: 2 row ratio (20.18q/ha). The pooled mean increases in chickpea equivalent yields due to 5: 1 and 5: 2 row ratios were 15.9 and 21.0 per cent and 12.9 and 17.8 per cent, respectively over sole chickpea and sole linseed. The least % pod damage (5.80) was observed in 3: 2 row ratio which was statistically at par with 4: 2 (T₇) and 5: 2 (T₈). However, these were significantly superior over 3: 1 (T₃), 4: 1 (T₄), 5: 1 (T₅) and sole chickpea (T₁).
