Abstract

A field experiment was conducted during 2016–19 to standardize the fertilizer dose and scheduling for growth, yield and quality of banana under subtropical conditions at Research Farm of ICAR-Central Institute for Subtropical Horticulture, Rehmankhera, Lucknow. The highest mean pseudo stem girth (60.24 cm), leaf area (6.922 m2) and cumulative fruit yield (94.60 t/ha) were recorded in 100% recommended dose of fertilizer (RDF) of N and K applied (40:25, 30:35, 30:25, 0.15) at different phenological stages of growth. Whereas, maximum B:C ratio (2.10) and Total Soluble Solids (21.7 OB) was recorded in 80% RDF of N and K applied (40:25, 30:35, 30:25, 0.15) at different stages of growth. Where as, mean nutrient use efficiency ((41.40 tons fruit/tons nutrient) was recorded in 60% RDF of N and K applied (10:10, 40:20, 30:20, 20:40) at vegetative growth, pre-flowering, flowering and bunch development stage in banana cultivar Grand Naine under subtropical conditions.

8 of 10 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
