Abstract
The present investigation entitled “Evaluation of intercrop and their pattern in onion seed crop” was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during season of 2018-19. The experimental treatments viz., T1-onion seed crop (sole ) 60 X 60 cm , T2-palak (sole) 15 X 5cm, T3-methi (sole) 20 X 10 cm , T4-onion + palak (one row) T5- onion + palak (two rows), T6- onion + palak (three rows), T7- onion + palak (broadcasting), T8- onion + methi (one row), T9- onion + methi (two rows) and T10- onion + methi (broadcasting) were laid out in a Randomized Block Design (RBD) with three replications. Based on the research investigation it was found that the Plant height, number of seed stalks bulb-1, length and diameter of flower stalks, number and weight of seeds umbel-1 and plant-1 were significantly higher in sole crop of onion than rest of the treatments. Sole crop of onion at spacing 60 X60 cm provided the maximum yield of seed per unit area. The leaf yield of palak was significantly higher with palak sole crop than intercropping treatments due to minimum competition between the plants for space and nutrients. Maximum net return (Rs 548175/ha) and B:C ratio (5.18) was recorded for onion+ palak (one row) after that treatment of onion+ methi (one row) gave a following net return of Rs. 544247/ha and B: C ratio of 5..16 Also onion + palak (one row) intercropping system gave highest onion seed equivalent yield (OEY) i.e.6.54 q/ha. It has been concluded that onion intercropped with palak (one row )could be more remunerative for earning maximum net returns than the onion sole crop.
