Abstract:
A field experiment was carried out in Jadiriya cumpas college of Agricultural
engineering sciences – Baghdad University in autumn season 2017-2018 to study
the effect of two factors, the first factor include five sources of manure O0 (without
adding) O1 (cow residue), O2 (maize shells) O3(sugar cane) and O4 (Nile flower)
with rate 30 ton h-1, and the second factor included was application of three level of
mineral fertilizer M0 (without adding) M1 (120 kg N + 60 kg P + 200 kg K) , M2
(240 kg N + 120 kg P + 400 kg K) kg h-1 on the growth and yield of potato, the experiment was laid out in a Randomized Complete Block Design (RCBD) with
three replicates, at the maturity stages were done measuring the plant height, dry
weight of shoot, tuber weight, yield of one plant and total yield of tubers, The
results analyses indicated that Interaction of organic fertilizer and mineral fertilizer
treatment M2O1 had given the highest values of the studied parameters, the height
plant was 91.46 cm, dry weight of shoot was 8.24 ton h-1 , tuber weight was 169.93
gm tuber-1, yield of one plant was 1068.99 gm plant-1and total yield of tubers was
57.06 ton h-1.
