Pasture Irrigation

In our previous reports it was mentioned that the flood irrigation in winter season at. the foot of Mt. Iwate has played an important role in the herbage production and soil improvement. In this experiment the production of Ladino clover irrigated for 60 days from winter to spring was the highest among the all plots containing the plot manured necessary and complete amounts of fertilizers without irrigation for pasture. On a view point of the: efficiency of water, 15 days irrigation in winter season was most efficient. And 1 or 2 days irrigation. immediately after each cutting in summer season brought the effect like topdressing fertilizers. Consequently, for the herbage production and soil improvement the irrigation for 15 days, in winter season. and 5 or 6 days in summer season was the most available of all plots examined.
