EFFECT OF DIFFERENT PLANT DENSITIES ON THE YIELD AND SOME SILAGE QUALITY CHARACTERISTICS OF GIANT KING GRASS (Pennisetum hybridum) UNDER MEDITERRANEAN CLIMATIC CONDITIONS

Abstract

ABSTRACT

 

The aims of this study were to determine the adaptability of giant king grass (Pennisetum hybridum) under Mediterranean climate conditions, and also to determine whether proper plant densities could improve growth and yield. Study site was located at Bornova, Turkey (38°27.236 N, 27°13.576 E and 20 m). Treatment consisted of four densities of plant population (D₁:57,143; D₂:28,571; D₃:19,048 and D₄:14,286 plant ha^-1) with three replicates per treatment in a randomized block design. Setts were planted in mid June of 2010 and allowed to grow for 4 full growing seasons. Average result of four years indicated that there were significant effects of plant densities on the dry matter yield and other yield characteristics of giant king grass but not on silage pH. It was recommended that the production of giant king grass using D₂ (70x50 cm) was the most successful planting density regarding the dry matter (32.6 t ha^-1) and crude protein yield to the regions with Mediterranean-type climates under irrigation.

 

Key words: Giant king grass, plant density, dry matter yield, silage quality.

Keywords

• Giant king grass, plant density, dry matter yield, silage quality
