Abstract

increasing the growth and production of jicama plants on alluvial soil. The research was conducted in Pontianak City from July to November 2022. The research was conducted using a factorial complete randomized design. The first factor was pruning time (without pruning, 6, 7 and 8 WAP), the second factor was the dose of NPK fertilizer (200 kg ha-1, 300 kg ha-1 and 400 kg ha-1). The results showed that the interaction of pruning time and doses of NPK fertilizer only played a role in influencing the tuber harvest index. When pruning the jicama plants did not show any difference in tuber diameter, tuber weight and harvest index, however, the pruning played a role in increasing tuber yields. It was seen that the pruning was done to obtain the best tuber yield compared to no pruning on tuber diameter, tuber weight and harvest index. . The application of NPK fertilizer at different doses plays a role in increasing plant growth and jicama plants production with the doses needed to produce the best growth and tubers, namely as much as 400 kg ha-1. INTISARIPenelitian bertujuan untuk mengkaji peran waktu pemangkasan, dosis pupuk NPK serta interaksi keduanya dalam meningkatkan pertumbuhan dan produksi tanaman bengkuang pada tanah aluvial. Penelitian dilaksanakan di Kota Pontianak pada bulan Juli - November 2022. Pelaksanaan penelitian disusun menggunakan rancangan acak lengkap faktorial. Faktor pertama waktu pemangkasan (tanpa pemangkasan, 6, 7, dan 8 MST), faktor kedua dosis pupuk NPK (200 kg/ha, 300 kg/ha dan 400 kg/ha). Hasil penelitian diperoleh interaksi dari perlakuan waktu pemangkasan dan dosis pupuk NPK hanya berperan dalam mempengaruhi indeks panen umbi. Waktu pemangkasan yang dilakukan terhadap tanaman bengkuang tidak menunjukkan perbedaan pada diameter umbi, bobot umbi dan indeks panen namun pemangkasan yang dilakukan berperan dalam meningkatkan hasil umbi terlihat adanya pemangkasan yang dilakukan diperoleh hasil umbi yang terbaik dibandingkan tanpa pemangkasan pada diameter umbi, bobot umbi dan indeks panen. Pengaplikasian pupuk NPK pada dosis yang berbeda berperan dalam meningkatkan pertumbuhan tanaman dan produksi umbi bengkuang dengan dosis yang diperlukan untuk menghasilkan pertumbuhan dan umbi terbaik yaitu sebanyak 400 kg/ha.

Abstract

The development of tidal land for agriculture faces various challenges in order to provide high productivity. One of the plant cultivation techniques developed in tidal areas is water saturated cultivation. This research aims to determine the growth and yield of flowering cabbage in acid sulphate tidal fields using a water-saturated cultivation system applied with various ameliorant compositions. This research was carried out in Kalimas village, Sungai Kakap District, Kubu Raya Regency for 8 months (April up to October). The research design that be used is a field experiment with a split plot design with 2 treatment factors and 3 replications. The main plot is the Flower Cabbage variety (K) which consists of 2 varieties: k1 = Larissa F1 and k2 = Snow White F1. As a subplot is the ameliorant composition (A) which consists of chicken manure (pka), goat manure (pkk), biological fertilizer (ph) and dolomite lime (kd) with 8 compositions, namely: a1 = pka, a2 = pkk, a3 = pka + ph a4 = pkk + ph, a5 = pka + kd, a6 = pkk + kd, a7 = pka + ph + kd, and a8 = pkk + ph + kd. The results of the research show that the ameliorant composition has the same effect, while the variety and depth of the water table have a different effect on the growth of flowering cabbage plants on acid sulfate tidal land with a water-saturated cultivation system. The Larissa variety provides better growth than the Snowhite variety.
