Experimental results on $\pi^0$ production in $K^+$p interactions at 8.2 GeV/$c$ incident momentum are presented. Average $\pi^0$ multiplicities for given prong numbers are evaluated. They are consistent both with the corresponding results for pp interactions at 12 GeV/$c$ chosen for comparison because they have the same average prong number) and with a model where total multiplicity distributions are calculated from the Czyżewski--Rybicki formula and the charge branching ratios from the statistical model. Some averages over the $\pi^0$ momentum distribution are also evaluated. In particular it is found that $\pi^0$-s produced in two prong interactions go predominantly forward.

The v and v nucleon total cross-sections have been determined as a function of energy using a sample of 2500 v and 950 v event. The results are compared with predictions of scaling and charge symmetry hypotheses.
