Five treatments were as 1. watering by can water 2. burying the baked clay canteens at the interval of one foot 3. burying the baked clay canteens at interval of 2 feet 4. burying the baked clay canteens at an interval of three feet and 5. burying the baked clay canteens at an interval of four feet, each of baked clay canteens contained five litres of water and was burried under the soil surface between rows of the experimental plants. The treatment of burying the baked clay at an interval of two feet produced the highest production of tomato, 3,047.926 kg/rai and soil moisture was 10.417 % weekly. The next one was the treatment of burying the baked clay canteen at an interval of one foot, 2,847.814 kg/rai and soil moisture was 12.919 % weekly. While applying water by using common watering method produced only 2,012.842 kg/rai and soil moisture was 7.578 % weekly. For the crop types they will be experimentally tested in the future.
