Abstract
The present investigation entitled “Effect of intercropping on growth and yield of brinjal and
palak” was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana
Agricultural University, Hisar during autumn-winter season of 2016-17. The experimental treatments
viz., T1-brinjal sole crop of 60 X 60 cm , T2-palak (sole) 20 X 5cm, T3-paired row brinjal sole crop
30/at spacing of 60 X 60 cm , T4-brinjal + palak (broadcasting) T5-brinjal + palak single row, T6-brinjal
+ palak two rows, T7-brinjal + palak three rows, T8-paired row brinjal + palak single row, T9-paired
row brinjal + palak two rows, T10-paired row brinjal + palak three rows and T11-paired row brinjal +
palak four rows were laid out in a Randomized Block Design (RBD) with three replications. Based on
the research investigation it was found that the intercropping of palak with brinjal significantly
decreased plant height (cm), number of fruits per plant, fruit characters, days to first picking and total
fruit yield (q/ha) in brinjal and leaf length, petiole length, leaf width, stem length, days to harvesting
and leaf yield (q/ha) in palak. Growth and yield attributes of sole brinjal (60 X 60 cm) and sole palak
(20 X 5 cm) exceeded over rest of the treatments due to minimum competition. Brinjal + palak single
row gave highest net returns (Rs. 222652) and B: C Ratio (3.76) due to low cost of production,
followed by treatment paired row brinjal + palak (two rows) with Net returns (Rs. 218052) and B: C
Ratio (3.52). Also Paired row brinjal + palak (two rows) intercropping system gave highest LER
(1.84), ATER (1.46), maximum Gross returns (Rs. 304598), BEY (507.6 q/ha) and PEY (217.6 q/ha)
followed by treatment Brinjal + palak single row with LER (1.76), ATER (1.43), Gross return (Rs.
303442), BEY(505.6n q/ha) and PEY(216.7 q/ha). It has been concluded that brinjal normal or
paired row intercropped with palak single row could be more remunerative for earning
maximum net returns than the brinjal sole crop.
