THE EFFECT OF FERTILIZATION AND REPEATED MOWING ON SOME VEGETATIVE CHARACTERISTICS AND YIELD OF PANICUM MOMBASA PLANT

Abstract

The experiment was perfumed according to (R.C.B.D) in triplet in field belongs to the department of crop sciences, college of Agricultre, university of Diyala, whose soil has a texture of Slity loam during spring season of 2019, to study the effect of addition of three different types of fertilizers to the soil which are Humic acid 300 kg.h-1, Trichoderma 75 kg.h-1 and NPK 200 Kg.h-1 , on the growth and characters of Panicum Maximum cv Mombasa. Results showed significant superiority of humic acid fertilizer after 40 days of fertilization with regards to the plant height, branches number, leaves number, leaf area, the total yield of green feed and hay yield. In fertilization treatment with tricoderma, the weed after 40 days was outstanding in the characters of the plant height, branches number, leaves number, leaf area, the total yield of green feed and hay yield, treatment with NPK, the cut after 40 days exceeded in the plant height , branches number, leaves number, leaf area , the total yield of green feed and the hay yield.
