Influence of different plant densities and fertilizer levels on growth and yield parameters in Banana cv. Grand Naine

Abstract

An experiment was carried out in banana cv. Grand Naine to evaluate the effect of three different plant densities with three
levels of fertilizer which was laid out in factorial RCBD design with three replications. During all the stages of growth, except plant
height, all the vegetative growth parameters were higher in lowest plant density (2.0 x 2.0 m) and lower in higher plant density (1.5 x1.5 m). The highest plant height (207.67 and 205.61 cm) and yield (108.33 and 101.95 tons/ha) was registered in higher plant density in both the plant and ratoon crop respectively. While the lowest plant height (197.25 cm and 194.19 cm) and yield (74.26 and 69.38tons/ha) was observed in lower plant density in both the seasons respectively. In case of fertilizer application, the significant result was obtained for growth and yield of banana. The highest growth and yield parameters was found in F2 (125 % RDF) whereas the lowest was registered in F3 (75 % RDF). For combined effect of plant density and fertilizer on growth and yield parameters, the treatment S3 x F2 (2 x 2 with 125 % RDF) recorded higher values except plant height and yield than other combinations.
