Pyongyang, October 14 (KCNA) — The township cooperative farm of Janggang county was successful in two- and three-crop-a-year system.
Normally, three-crop farming is considered a tough and tricky job because of its longer period of cultivation, labour-intensive tending and its adverse effect on oil fertility.
It is much more a challenge in Janggang, a northern alpine area with poor land fertility and a shorter period of crop growth.
These disadvantages never deterred chairperson Pak Ok Hui of the farm management board and farmers who buckled down to three-crop farming.
They began with the building of a greenhouse. Despite a number of difficulties, they finally completed tiered greenhouse 650 square metres wide. Humus-pot seedlings of red radish were grown as the first crop, potato as the second and humus-pot seedlings of white cabbages as the third.
The per-hectare yields of spring radish and potatoes were 20 and 45 tons respectively, and those of autumn vegetables are estimated at 100 tons.
The greenhouse is also an efficient vegetable producer.
The farm paid close attention to the improvement of soil fertility, the key to successful three-crop farming.
It pushed forward the output of bio-active manure and fermented manure with microbial liquid and got every work-team to produce slaked lime from kilns, so as to spread sufficient manure on the fields. It also expanded its microbial fertilizer factory to produce manure by using agricultural by-products.
The farm has experimental plots for cultivating dry-field rice and potato seeds.
The farm plans to increase arable land for three-crop farming next year.
