ABSTRACT

A field experiment was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar (Haryana) during rabi season of 2013-14 and 2014-15 to investigate the effect of fertilizers and plant spacing on growth and seed yield of onion. The treatments comprising of three fertilizers levels (F1: 75% recommended dose of phosphorous and potash, F2: 100% recommended dose of phosphorous and potash and F3: 125% recommended dose of phosphorous and potash) and four plant spacing (S1: 45x30 cm, S2: 45x45 cm, S3:60x30 cm and S4: 60x45 cm) were laid out in randomized block design (factorial). The results of the experiment showed that different fertilizers levels and plant spacing influenced the growth and seed yield of onion significantly. The crop planted at 60x45 cm spacing and supplied with 125% recommended dose of phosphorous and potash resulted in maximum number of umbels per plant and number of seeds per umbel, while the crop planted at 45x30 cm spacing and supplied with 125% recommended dose of phosphorous and potash resulted in highest length of leaves, length of flower stalk and seed yield per hectare during both the years.
