Abstract

Fertilizer and maturity stage affect the nutritional content and quality of tomatoes. This study aimed to obtain the best dosage of amino acid fertilizer on the qualities and shelf life and to determine the effect of the maturity stage on the qualities of Servo tomatoes. The research design used factorial RCBD with 3 blocks as replications. The Servo tomatoes were grown in Wonosobo District and foliar fertilized with 4 levels of amino acid fertilizer, namely 0, 1, 2, and 4 L ha-1 amino acid fertilizer, and 2 L ha-1 comparison fertilizer. Observation of tomato fruit quality was conducted in Horticulture Sublaboratory, UGM at 27,5 °C with relative humidity of 73%. The quality observed was CO2 concentration, visual quality rating, weight loss, fruit firmness, fruit color, TSS, TTA, carotenoids, lycopene, flavonoids, and vitamin C. The observation was terminated when the score of VQR reached 3 as shelf life of tomatoes. Amino acid fertilizer can improve the quality of Servo tomatoes as seen from the parameters of fruit color (a*) and total titrated acid (TTA). In terms of other parameters, the amino acid fertilizer does not affect the quality of Servo tomatoes. The highest value on fruit color (a*) and TTA resulted from 2 L ha-1 of amino acid fertilizer. The maturity stage significantly affects the quality improvement of fruit firmness, weight loss, VQR, CO2 concentration, TTA, total soluble solids, carotenoids, and flavonoids.

Abstract

Cherelle wilt merupakan penyakit fisiologis pada tahap awal perkembangan buah kakao karena kegagalan perkembangan buah. Salah satu unsur yang diduga kuat menjadi penyebab adalah unsur boron yang ketersediannya sangat penting bagi tanaman karena berperan dalam perkembangan sel, metabolisme protein, asam amino, nitrat, lemak, karbohidrat, auksin dan fenol, fungsi membran, berperan dalam keberhasilan pembentukan bunga, pembuahan dan perkembangan buah. Tujuan penelitian untuk mengkaji dan meneliti tentang pengaruh boron terhadap layu pentil kakao. Penelitian dirancang menggunakan rancangan Randomized Complete Block Design (RCBD) dimana faktor A terdiri dari metode aplikasi pupuk yaitu lewat daun dan lewat tanah sedangkan faktor B adalah takaran pemberian boron yang terdiri dari tanpa pemberian pupuk , pemberian boron 1,5 g.pohon-1, 3 g. Pohon-1, 4,5 g.pohon-1 dan 6 g.pohon-1 setiap perlakuan diulang tiga kali, setiap ulangan terdiri dari 5 tanaman sehingga kombinasi perlakuan menjadi 2 x 5 x 3 x 5 = 150 tanaman. Parameter yang diamati adalah Boron total daun, viabilitas pollen, total pentil yang terbentuk, persentase pentil sehat, dan pentil layu. Hasil menunjukkan bahwa metode aplikasi pupuk boron berpengaruh terhadap layu pentil kakao. Metode aplikasi boron lewat daun dengan dosis 0, 4,5 dan 6 g.tanaman-1 memberikan nilai pentil layu yang lebih tinggi. Sedangkan metode aplikasi boron lewat daun dosis 1,5, dan 3 g.tanaman-1 serta metode aplikasi lewat tanah dosis 6 g.tanaman-1 memberikan persentase pentil sehat yang lebih tinggi. Metode aplikasi lewat daun dengan dosis 3 g.tanaman-1 adalah dosis maksimal yang mampu memberikan hasil tertinggi terhadap viabilitas pollen, jumlah buah, dan persentase pentil sehat.
