Weeders

Why do we want them?•While SRI can increase weed pressure, weeders can reduce drudgery and time spent hand-weeding.

•Weeders are especially important where labor is expensive or not available.

•Mechanical weeders aerate the soil, which improves root health and can increase nutrient uptake by plants

•Lack of mechanized equipment to manage weeds limits scaling-up of SRI to larger-scale farmers

Weeders for rainfed conditions

?I want a weeder!

What now?!!

•How do I know which weeder to get?Which one works best with my …..- soil type? - Weed pressure and weed types? - Plant spacing? - Weeding schedule?

•How can I get one?- Where can I buy it?- Can I afford it?- If I want to make it myself , where can I get a technical drawing?

•Can it be easily used and maintained?- Is it too heavy? Can women use it easily?- Will it break down easily?- Are spare parts available? - Is it adjustable?- Is it easy to repair?

•How much labor will I save?

Markers

Markers help plant in a square pattern so that..

• weeding can be done in both directions• optimal spacing for plant growth is maintained..
