Response of nitrogen and bio-fertilizers on growth and yield of banana cv. Grand Nain

Abstract

Banana (Musa spp.) is one of the important fruit crops of the tropics. Higher productivity in banana is possible through improved planting material and nutritional management. The objective of experiment includes studying the response of various level of nitrogen and bio fertilizer on growth and yield parameters of banana. The experiment contains fifteen (15) treatment combinations with three replications laid out in a randomized block design with factorial concept. The treatment consists as three levels of nitrogen (100%, 80% and 60%) and five levels of bio-fertilizers (Azotobacter, Azospirillum, Rhizobium, 50% of B1 + 50% of B2+ 50% of B3 and No bio-fertilizer (Control)). The treatment received 100% recommended dose of nitrogen (RDN) along with Azotobacter (20ml two times) noted positive reaction towards all growth parameters also significantly positive response to yield parameters i.e. weight of bunch (kg) number of hands per bunch, number of fingers per bunch, weight of third hand (kg), yield (t/ha).
