Rice Ratooning
In areas where adequate water is available after the first crop season, rice ratooning could be practised as an alternative to raising of the second crop in rice double cropping. The ratoon crop matures earlier and requires less labour and water inputs. Water use efficiency is high. Early maturing, high yielding first crop varieties like No.11 and Barket are suitable for ratooning.
The success of a good ratoon crop depends on the care with which the first crop is cultivated in the growing season. Agronomic practices for the first crop determine the success of ratooning and grain yields of ratoonable varieties. Variations in soil, water, light and temperature influence ratooning ability. Tiller development is highly influenced by the carbohydrates that remain in the stubbles and roots after harvest and the level of nitrogen in the soil. Varieties with thick culms/stems store more carbohydrates and are more suitable for ratooning. download full details here
Seedling Prod Practice
Good for areas where irrigation is not assured, where shochum is common, and in areas where low temperature is a problem at the seedling stages. download full details here
Wheat Production
About 65% of the wheat area in Bhutan is wheat grown after rice. All varieties grown in the rice-wheat system are introduced spring wheat. Winter wheats requiring vernalization are grown in temperate (high altitude) areas. download full details here
