This
research aimed to analyse the effect of biopesticide and organic liquid
fertilizer on weight and quality of apple. The study was carried out in
Bumiaji, Batu, East Java (805'S, 11280'E, 1400 m in altitude) on July
-December 2013. The liquid organic
fertilizer (LOF) was produced from
water mixed with nitrogen source such asmanure, urin, legume leaves,
phosphoric powder and an energy source such as molasses or sugar juice
This mixture was fermented with local microorganism. Biopesticide was
extracted from Mahogany seed powder and Sour sop leaves and mix with
LOF to get a combination (CB) treatment. Two treatments and a control
wereapplied in different fields. First treatment consisted of
application of the liquid organic fertilizer (LOF), while the second
consisted of combination of the liquid organic fertilizer and
biopesticide (CB). Five
trees were selected per field for data
collection. Application of LOF and CB were conducted every two weeks
untill fruit harvest. Control was conducted in a field with regular
cultivation. Result showed that both treatments increase the weight of
apple production.
Mean
of individual apple weight with CB treatment is slightly higher (115.56
± 29.99 gr/ind) than that with LOF treatment (112.72 ± 9.09 gr/ind).
The effect of both of treatments by applying liquid organic fertilizer
(LOF) and combination (CB) has increased the apple weight (29.8% and
33.1% respectively). In general both treatments have shown to increase
glucose content, Vitamin C and Calcium content in apple fruits.
