Upaya Meningkatkan Produksi dan Kualitas Buah Jambu Biji Kristal (Psidium guajava L. cv. Kristal) Melalui Pemupukan
Abstract: Nowadays “Kristal”
guava variety (Psidium Guajava L. cv. Kristal) is very popular for consumers
because it has several advantages such as flesh fruit is crunchy, sweet-sour
taste with slightly seeds or seedless, and shelf life of fruit relatively long
that can be up to 1 month if stored at temperature of 10-15 oC. The challenge
faced by farmers are the production and fruit quality still low, due to
inadequate maintenance done. This research was conducted to study the effect of
fertilizer to increase the production and quality of “Kristal” guava variety.
Research was carried out in farmers garden at Pelaga Village, District of
Petang, Badung Regency, Bali, from April-November 2016. The study was a
randomized block design (RBD) with fertilizer treatment consisted of 4 levels
and each repeated 6 times. The results showed that fertilization increase
production and quality of “Kristal” guava fruit compared to the control. The
highest weight of fruit per plant (18.28 kg / plant) were obtained on plants
fertilized with compost 5kg/plant + urea 200 g/plant + KCl 250 g/plant + TSP
250 g/plant + gypsum 500 g/plant+ micro fertilizer CuSO4 and ZnSO4 1.5 g/plant,
respectively, given once at the beginning of the study and significantly
different compared to the lowest weight of fruit per plant which obtained on
controls (8.99 kg/plant). The highest fruit diameter (8.72 cm) obtained on
plants fertilized with compost 5kg/plant + urea 200 g/plant + KCl 250 g /plant
+ TSP 250 g / plant + gypsum 500 g/plant + micro fertilizer CuSO4 and ZnSO4
each 1.5 g/plant, respectively, given three times i.e at the beginning of the
study, at the phase of anthesis, and at the maturity of fruit and significantly
different compared to control (7,50 cm).
