Comparison of Changing Cultivation Pattern on Morphological and Biochemical Characteristics of Forage of Two Types of Crop Legumes in The Tropical Climate of Southern Kerman Province

Reduction of the quantity and quality forage is one main restrictions on productivity livestock systems. Tropical legumes are most important crops to improve feeds and, thus, for providing products human consumption in arid regions. In order investigate shift cultivation date two from summer spring weather conditions, a factorial experiment randomized complete block design with three replication was conducted at Agricultural Research Institute south Kerman, Iran, during cropping seasons. Treatment planting tropical (Tapary bean cowpea). The results showed that changing dates led significant effect seed yield region. All agronomic traits cowpea increased compared Tepary due differences their genetic backgrounds. were not different terms nitrogen, crude protein, ash. On all dates, hemicellulose-free cell wall higher than Tepary. contrast, neutral detergent fiber observed more cowpea. highest dry matter index recorded Whereas digestibility, net energy lactation, metabolizable related According physiological phenological responses legumes, it necessary examine selection suitable improving quantitative qualitative forage.
