A comparative study on the yield of broadcast of planting radish was conducted from November to 1975 to January 1976 at the College experimental field.

A 23x20 meters field was prepared thoroughly by the use of ordinary farm implements. The entire field was divided into two beds to represent the two treatments. Each bed was further subdivided into twelve blocks of 2x 1/2 meters. The two treatments were replicated six times and each replication representing each treatment were distributed at random in the experimental field.

Planting was done on November 16, 1975. Four hundred grams of seeds were planted directly and evenly in rows 25 centimeters apart on every plot. Each plot was composed of ten rows. In the broadcast method, the seeds were broadcasted evenly on the block and covered with soil by passing the rake at the top.

The plants were fertilized twice: the first application was done on November 30, 1975 and the second application was done 15 days after the first application. Ammonium sulfate was used at the rate of 400 kilograms per hectare in both treatments.

Thinning was done 20 days after germination or when the plants were about three to four inches tall.

When the plants were about one month old, weeding was done to prevent the competition of weeds on the plant food, moisture and light.

The plants were sprayed three times to prevent the occurrence of pests and diseases. These were done with the use of Turbiden for the first spray and Malathion for the second and the last spray.

There was no sign of infestation. However there were few ants and whorl maggots that damaged the young plants but they were easily controlled by spraying Turbidan and Malathion.

The same treatment was employed diligently to overcome the drying of some leaves at the early stage and to anticipate the fast rotting of the roots.

Plants were harvested by hand pulling one at a time from the central proportion of the experiment 60 days after planting.

Harvesting and gathering data such as plant weights, root weights, length and diameter of roots were taken.

The two treatments, drill and broadcast methods of radish culture varied significantly. Plants planted by the drill method produced better yield as compared to those of the broadcast method. Hence, this study had shown the advantage of the drill method over the broadcast method of planting radish.
