PENGARUH KANDUNGAN AIR TANAH DAN PUTARAN BAJAK ROTARY TERHADAP KARAKTERISTIK TANAH TERBAJAK
ABSTRACT: The aim of this
research was to find out the best soil tilt as affected by the moisture content
of the soil and rotation speed of rotary tiller. A randomized block design
experiment was conducted at Balai Benih Induk Palawija, Bedali Lawang, Malang
Regency, from October 2002 until January 2003, in three replicates. The measurements were carried out on the tilt
soil i.e. the tillage depth and mean weight diameter, the porosity and bulk density
of soil, surface roughness of soil, penetration resistance of soil and shear
strength of soil.
The results indicated that both, the moisture content of soil as well as
the rotation speed of the rotary tiller and their interactions significantly
affects the above-mentioned parameters. The best tilt soil was found on the use
of the rotary tiller at 90 rpm on the soil having moisture content plastic
limit of 1.0 and the tillage was carried in two times.
Key words: Rotary tiller,
moisture content, rotary speed, plastic limit
