Implication

Randomized trial demonstrates improved soil health and fruit quality in apple trees using biofertilizer in nutrient-poor soils, suggesting sustainable agricultural practices.

Key Points

The aim was to evaluate the effects of castor bean enzyme biofertilizer on apple yield and nutritional quality in degraded sandy soils.
Conducted a two-year field experiment on 7-year-old ‘Saiwaihong’ apple trees under randomized complete block design.
Applied six treatments including unfertilized control, cattle manure, compound fertilizer, and three rates of biofertilizer.
Evaluated soil properties, enzyme activities, fruit yield, and quality parameters systematically.
CB application reduced soil pH and increased organic matter by 50.9-70.6% compared to control.
The B2 treatment significantly enhanced fruit vitamin C content by 101.4-135.9% across both years.
Strong correlations were found between soil enzyme activities and improved fruit quality parameters.
