KEMAMPUAN DOSIS PUPUK ZA DAN WAKTU PEWIWILAN TUNAS LATERAL TERHADAP HASIL DAN KUALITAS CABAI BESAR
Abstract
[ENGLISH]
Chili is one of the horticultural commodities which have high economic value and have a large export opportunities. The development of technology makes great chili farming business will be more profitable. The purpose of research to determine the interaction between fertilizer dosing ZA and pruning time of lateral shoots that are most influential to the outcome and quality of hot pepper. Factorial (3 x 3) research carried out using Random Design Group. The first factor is the fertilizer doses studied with 3 threshold ZA covers: N1, N2, and N3, respectively 14, 28, and 42 grams per plant. The second factor is the time of pruning with 3 degrees include: W1, W2, and W3, each for 0, 15, and 25 days after planting. The results showed that the combination treatment of ZA 28 gram per plant and prunning of lateral shoots in 15 dat tend to the best result on the yield and quality of chilli.

Cabai merupakan salah satu komoditas hortikultura yang memiliki nilai ekonomi tinggi serta memiliki peluang eksport yang besar. Perkembangan teknologi menjadikan usaha pertanian cabai besar akan semakin menguntungkan. Tujuan penelitian untuk mengetahui interaksi antara pemberian dosis pupuk ZA dan waktu pewiwilan tunas lateral yang berpengaruh paling baik terhadap hasil dan kualitas cabai besar. Penelitian faktorial (3x3) dilaksanakan menggunakan Rancangan Acak Kelompok. Faktor pertama yang diteliti adalah dosis pupuk ZA dengan 3 taraf yang meliputi: N1, N2, dan N3 ,masing-masing 14, 28, dan 42 gram per tanaman. Faktor kedua adalah waktu pewiwilan dengan 3 taraf meliputi: W1, W2, dan W3, masing- masing untuk 0, 15, dan 25 hari setelah tanam. Hasil penelitian menunjukkan bahwa kombinasi perlakuan ZA 28g/tanaman dan pewiwilan tunas lateral umur 15 hari setelah tanam cenderung memberikan hasil terbaik terhadap hasil dan kualitas cabai besar.
Kata Kunci: Cabai Besar; Dosis Pupuk ZA; Nitrogen; Pewiwilan.
