Abstract

The Cauliflower (Brassica oleraceae var botrytis L.) is a potential horticultural commodity that has great prospects for intensive development in the lowlands. The vitamin and fiber content in cauliflower is so abundant that it is very good for the human body. Cauliflowers can be cultivated on several types of mineral soil, one of which is acid sulfate mineral soil. Problems in acid sulfate mineral soils contain high clay, high soil acidity, a pyrite layer, and nutrient deficiencies. Efforts can be made to support the growth of cauliflower by applying a soil saturated culture system, providing combination of goat manure + bioboost + dolomite, and using lowland cauliflower varieties. The research location is at Golden River Camp Kalimas Village, Sungai Kakap District, Kubu Raya Regency. The research took place from July to November, 2023. The research design used was a Split Block Design, consisting of 2 treatment factors and repeated 3 times and consisting of 4 sample plants. The first factor is the variety as the main plot with 2 treatment levels (Larissa and Snow White) and the second factor is the combination of ts (goat manure ton/ha + bioboost ml/l + dolomite ton/ha) as a subplot with 4 treatment levels. The variables observed in this study consisted of the number of leaves (strands), leaf area (cm2), fresh weight of upper plants (g), dry weight of upper plants (g), age of flower appearance (hst), crop diameter (g) and crop weight (g). The results showed that there was a different response between the two varieties and the combination of goat manure + bioboost + dolomite on the growth and yield of cauliflower, The Larissa variety showed better growth and yield when compared to the Snow white variety and the combination of goat manure 10 tons/ha + bioboost 15 ml/l + dolomite 2 tons/ha can increase the growth and yield of cauliflower better than other ts combinations on tidal acid sulphate soil with soil  saturated culture system.

Abstract

            The use of manure and lime in cultivation of cauliflower plants on acid sulfate alluvial soil can improve the physical, chemical and biological properties of the soil so that it can increase the growth and yield of cauliflower. The aim of this research is to determine the best combination of manure and lime for the growth and yield of two cauliflower varieties planted on tidal land with a saturated soil culture system. The research location is located at Golden River Camp, Jalan Kalimas Tengah, Kalimas Village, Sui. Kakap District, Kubu Raya Regency, West Kalimantan. The research period was from July to November, 2023. The research design used Split Block with two treatment factors and was repeated in 3 times. The first factor consists of 2 levels, namely the Larissa and Snow White varieties. The second factor was a combination of manure and lime treatment, consisting of 4 levels, namely chicken manure; goat manure; chicken manure + lime; and goat manure + lime. The variables observed were number of leaves, fresh weight, dry weight, leaf area, flower emergence time, crop weight, and crop diameter. The research results showed that the Larissa variety with a combination of goat manure + lime showed better growth and yield than the Snow White variety. Key words: acid sulfate alluvial; cauliflower; lime; saturated soil culture system; tidal land INTISARIPenggunaan pupuk kandang dan kapur dalam budidaya tanaman kubis bunga pada tanah aluvial sulfat masam dapat memperbaiki sifat fisik, kimia, dan biologi tanah sehingga dapat meningkatkan pertumbuhan dan hasil kubis bunga. Tujuan penelitian ini adalah untuk mengetahui  kombinasi terbaik pupuk kandang dan kapur terhadap pertumbuhan dan hasil dua varietas kubis bunga  yang ditanam di lahan pasang surut dengan sistem budidaya jenuh air. Lokasi penelitian terletak di Golden River Camp, Jalan Kalimas Tengah, Desa Kalimas, Kecamatan Sui.Kakap, Kabupaten Kubu Raya, Kalimantan Barat. Waktu penelitian mulai bulan Juli hingga November 2023. Rancangan penelitian menggunakan Split Block dengan dua faktor perlakuan dan diulang 3 kali. Faktor pertama terdiri dari 2 taraf, yaitu varietas Larissa dan Snow White. Faktor kedua perlakuan kombinasi pupuk kandang dan kapur, terdiri dari 4 taraf, yaitu pupuk kandang ayam;  pupuk kandang kambing; pupuk kandang ayam + kapur; dan pupuk kandang kambing + kapur.  Variabel yang diamati adalah jumlah daun, berat segar, berat kering, luas daun, saat munculnya bunga, berat krop, dan diameter krop. Hasil penelitian menunjukkan bahwa varietas Larissa dengan kombinasi pupuk kandang kambing + kapur menunjukkan pertumbuhan dan hasil yang lebih baik dibanding varietas Snow White. Kata kunci: alluvial sulfat masam, budidaya jenuh air, kapur, kubis bunga, lahan pasang surut
