Abstract

Pengembangan stroberi di dataran rendah Indonesia masih terbatas, tetapi bisa menjadi peluang untuk memperluas area budidaya stroberi. Budidaya stroberi di dataran rendah akan menghadapi tantangan baru, terutama serangan hama dan penyakit. Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan intensitas naungan dan varietas terhadap serangan hama dan penyakit tanaman stroberi di dataran rendah. Penelitian ini menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) Tersarang dengan dua faktor. Faktor utama terdiri atas empat taraf yaitu kontrol (P3), naungan 55% (P1), naungan 65% (P2), dan naungan 75% (P4). Faktor tersarang terdiri atas tiga varietas stroberi, yaitu varietas California (R1), varietas Mencir (R2), dan varietas Sweet Charlie (R3). Dengan demikian, terdapat 12 kombinasi perlakuan dengan 4 ulangan, masing-masing ulangan terdiri atas 3 sampel tanaman sehingga diperoleh total 144 tanaman. Hasil menunjukkan bahwa hama yang menyerang tanaman stroberi meliputi ulat grayak, ulat penggulung daun, belalang, kutu putih, sedangkan penyakit yang menyerang meliputi embun tepung, dan busuk buah. Naungan 75% meningkatkan kerusakan daun tertinggi akibat hama pada kontrol sebesar 8.2%, varietas Mencir lebih rentan akibat kerusakan buah dibanding Sweet Charlie sebesar 0.14%. Terdapat korelasi positif antara intensitas cahaya dan suhu udara terhadap intensitas serangan hama dan penyakit, namun kelembaban udara menunjukkan korelasi negatif dengan serangan hama dan penyakit.

Abstract

The demand for fruits in Indonesia continues to increase along with the increase in public consumption. Melon is one of the fruits that requires intensive handling in its cultivation because it is vulnerable to environmental changes and diseases. This study aims to determine the effectiveness of adding KCL and KNO3 fertilizers on the growth and yield of two melon varieties. This study used a non-factor randomized complete block design (RCBD). There were four treatments consisting of a combination of fertilizers and melon varieties, namely P1 (KCL and new madesta varieties), P2 (KNO3 and new madesta varieties), P3 (KNO3 and glamour varieties), P4 (KCL, KNO3 and new madesta varieties), with 6 replications so that there were 24 experimental units. The results showed that P3 treatment gave the best results in stem diameter, number of leaves, early flowering age, fruit weight and fruit diameter. P2 treatment gave the highest average yield on the parameters of fruit flesh thickness and total soluble solids (PTT). P3 treatment has the potential for further research, P3 treatment can fulfill the expected criteria with the highest fruit weight of most treatments. The provision of alternative K sources did not give a real response to melon plants, thus it would be more efficient to use K sources that are more economical in the melon cultivation system carried out.
