“In order to reap a rich and stable harvest even in unfavourable farming conditions, it is important to introduce better seeds and more profitable and effective farming technology and methods. Now we are redoubling our efforts to present even one more valuable research finding much awaited and welcomed by agricultural workers,” said an official of the Academy of Agricultural Science.
High-yielding rice varieties newly bred by the Hamhung branch of the Rice Research Institute have been very popular at many farms on the east coast in recent years.
At present, they are regarded as the major promising varieties in the east coastal areas. They are also being cultivated in the low-yielding areas such as tideland-turned ricefields and rain-dependent paddies on the west coast.
The Agricultural Chemistry Institute researched and introduced green chemical insecticides, which inflict less damage on the environment, one after another.
Among them is the mixed insecticide, an agrochemical made by mixing components good for treating soil and plants in growing period and which helps exterminate various kinds of harmful insects on paddy rice while increasing per-hectare yield.
According to scientists, a spray of the insecticide on rice seedlings not only helps paddy rice continuously maintain its self-defence capacity until mid-June when the outbreak of harmful insects is the most frequent, but also reduces the damage by various kinds of harmful insects by over 85 percent.
It can also reduce a large amount of the agrochemical to be used, while saving much labour.
Costing low and highly efficient, these agrochemicals were introduced into many farms across the country and fully proved advantageous and effective.
The Agricultural Informatization Institute pushes forward with a research project to raise the accuracy of the estimated paddy rice and maize crops.
Pae Song Nam, director of the institute, said that they estimate the crops of paddy rice and maize more correctly by improving the agricultural crop growth simulation system established long ago.
The academy also encourages cooperation with the hydro-meteorological sector to further detail the forecasts about the growth of agricultural crops so that relevant units can take advance agro-technical measures according to the right time.
