    Abstract
    Soil physics is an important factor for plant growth. The objective of this research is to study the physical properties of ultisol soil by using compost planting with pakcoy (Brassica rapa L.) with different water level. Research was done on greenhouse scale using a completely non factorial randomized design, consisting of 3 treatments and 8 replications, ie 100 % water supply of field capacity, water supply of 80 % field capacity, and water supply at 60 % of field capacity. Parameters observed were soil texture, organic matter, porosity, soil temperature, soil permeability, evapotranspiration, wet weight and dry weight of the plant. The results showed that the soil was sandy loam textured ultisol soil, soil organic matter was 5,69 %, in average porosity was ranged from 52,23 to 54,50 %, average soil temperature was 30,5oC, permeability was ranged from 6,15 to 7,76 cm/h, evapotranspiration was ranged from 0,66 to 0,68 mm/d, wet weight of pakcoy plants was ranging from 57,5 to 70 g and dry weight of plants was ranged from 3,61 to 5,09 g.
     
    Sifat fisika tanah merupakan faktor penting bagi pertumbuhan tanaman. Penelitian ini bertujuan untuk mengkaji sifat fisika tanah ultisol menggunakan pembenah kompos bertanaman pakcoy (Brassica rapa L.) dengan tingkat pemberian air berbeda. Penelitian dalam skala rumah kaca menggunakan rancangan acak lengkap non faktorial, terdiri dari 3 perlakuan dan 8 ulangan, yaitu pemberian air 100 % kapasitas lapang, pemberian air 80 % kapasitas lapang, pemberian air 60 % kapasitas lapang. Parameter yang diamati meliputi tekstur tanah, bahan organik, porositas, suhu tanah, permeabilitas tanah, evapotranspirasi, berat basah dan berat kering tanaman. Hasil penelitian menunjukkan jenis tanah ultisol bertekstur lempung berpasir, bahan organik tanah rata-rata 5,69 %, porositas berkisar 52,23 – 54,50 %, suhu tanah rata-rata 30,5oC, permeabilitas berkisar 6,15 – 7,76 cm/jam, evapotranspirasi berkisar 0,66 – 0,68 mm/hari, berat basah tanaman pakcoy berkisar 57,5 – 70 g dan berat kering tanaman berkisar 3,61 – 5,09 g.
