Response of nitrogen and Azospirillum inoculation on growth and yield of onion (Allium cepa L.) cv. pusa red

The present investigation was carried out at main horticulture research farm of Post Graduate College Ghazipur, . during the winter season of year 2015-16. The application of nitrogen along with Azospirillum increased the growth and yield of onion. Two biofertilizer treatments (B0=control and B1= Azospirillum) was treated at four different levels of nitrogen (N0= no nitrogen, N1= 80kg ha-1 , N2= 100kg ha-1 , N3= 120kg ha-1 ) on onion cv. Pusa Red. The experiment was conducted in randomized block design with 3 replications. The maximum plant height cm, leaf length cm, number of leaves per plant , diameter of bulb cm, weight of bulb g, bulb yield ( ha-1 ) was found by applying 120 kg ha-1 along with (B1N3) Azospirillum. However, the maximum yield was recorded ( q h-1 ) with rest doses of nitrogen and Azospirillum. | Response of nitrogen and Azospirillum inoculation on growth and yield of onion (Allium cepa L.) cv. pusa red
