kũhũthĩra
- to apply, use. To apply. To put into use or action; in agriculture, specifically refers to applying fertilizers (top dressing), pesticides, or using agricultural inputs, planting materials, or irrigation methods; also means to be used for a purpose (as in potato varieties used for specific cooking methods).
Example: Hihi kũgũria mbura nĩ ũndũ wa bata kũhũra waru bũrũri-inĩ wa Kenya? Nĩ njĩra irĩkũ ciagĩrĩire kũhũthĩrũo? (Is top dressing important in potato production in Kenya ? What are the recommended practices?); Kĩndũ kĩu kĩagĩrĩire kũhumbwo na tĩĩri o na ihenya thutha wa kũhũthĩrũo. (It should be covered by soil immediately after application.); Thĩinĩ wa mĩgũnda ĩmwe kũhũthĩrũo maaĩ na njĩra ya gũitĩrĩria maaĩ nĩ gũgatũma tĩĩri ũingĩhe Kwoguo riera rĩgatuĩka thĩna na waru ikũraga kahora na gũgetha gũgatuĩka ũndũ mũritũ. (In some soils the use of sprinkler irrigation will compact the soil so oxygen becomes a problem and the potatoes grow slowly and harvesting becomes difficult.)
