Coffee bean Katim CIFC7963

characteristics

Coffea arabica belongs to katim high-generation varieties, plant medium dwarf, vigorous growth, secondary characters stable, crown bud green leaves, the whole plant leaves thick green, cylindrical plant shape, short internodes, more branches, vigorous growth, wide adaptability, drought resistance, has a certain cold resistance, in the medium management level, the average dry bean yield of more than 200 kg. 3846 seeds per kg of seeds after 2 months in the sun. The germination percentage of seeds was above 95% within two months after seed production, 85% within three months, and then weakened after three months. Most seeds lost germination percentage after six months. The resistance to leaf rust is subimmune or extremely resistant. Its plant type is compact. It has certain inhibition on longicorn beetle which lays eggs mostly on bare parts of branches. It has high yield, no outstanding age phenomenon and excellent quality. It has been the main variety in coffee production since planting.

yield performance

The results of trial planting in different ecological areas showed that if the high yield cultivation techniques were followed, higher yield would be obtained. The average yield per mu was more than 150 kg, and the small area could reach more than 400 kg.

1. The state-owned Lujiang Farm in Baoshan City was planted in March 1991 with an area of 12.6 mu. There was no shade and irrigation once in dry season. The level of management and fertilization was medium. The fruit was produced in 1993. The average yield per mu in 1993/94 was 75 kg. In 1994/95, the average yield per mu was 350 kg. In 1995/96, the average yield per mu was 225 kg. The average yield per mu in three years was 217 kg. The yield was 36% higher than that of Tibika and Bobang.(The average yield of iron pica and wave bang is 160 kg per mu).

2. Dehong Institute of Tropical Agricultural Sciences, Yunnan Province, planted 30 mu in 1991, irrigated without shade and water, with medium fertilization and management level. The average yield per mu in 93/94 was 304.3 kg, 294 kg in 94/95, 222.5 kg in 1995/96, and 273.6 kg per mu in three years. The yield was 82% higher than that of S288 (S288 average yield per mu was 150 kg).

3. Ninger County Coffee Company planted 50 mu coffee base in July 1998. The site environment was not shaded, the management level was medium, the fertilizer level was low, but the soil fertility was high. The fruit began to bear in 2000. The average yield per mu in 2001/2002 was 285 kg, the average yield per mu in 2002/2003 was 340 kg, the average yield per mu in 2003/2004 was 293 kg, and the average yield per mu in three years was 306 kg. The yield was 53% higher than PT and 91% higher than P4 (PT 200 kg/mu, P4 160 kg/mu).
