Effect of nitrogen on the growth, development and yield of winter wheat

Abstract

In a split-plot experiment two levels each of P. and K and three levels of 8» were applied with the seed to winter sown wheat. Observations made on the growth of the crop showed?

(a) No significant effect of N. P. and K. or their inter-actions on the survival of seedlings and their early establishment.

(b) A significant increase in shoot number per plant with 601b. of nitrogen per acre; no effect of nitrogen on the shoot height and ear number.

(c) A significant increase in shoot number, shoot height and. ear number brought about 3 cwt. of superphosphate per acre.

(d) No effect of 3 cwt. of muriate of potash per acre on any of the observations made.
