Studies on High Production of Forage Crops on Paddy Field converted to Upland Condition : I. Effects of Much Nitrogen Fertilization on Growth, Yield and Nutritive Value of Teosinte

Abstract

We carried out the investigation on the effects of much nitrogene fertilization on growth, yield and nutritive value of teosinte. Results obtained were as follows: 1. The yield of fresh matter was increased by the increasing amount of nitrogene but the rate of increase was decreased by nitrogene dressing over 45kg per 10a. 2. As regards to contents of inorganic components, N was increased and K_2O decreased, while P_2O_5 was not affected at all by the increasing amount of nitrogen. 3. Percentage and yield of D. C. P. were increased greatly, on the contrary T. D. N. was effected so much.
