    DETERMINING QUALITY TRAITS OF SOME CONCENTRATE FEEDSTUFFS AND ASSESSMENTS ON RELATIONS BETWEEN THE FEEDS AND THE TRAITS USING BIPLOT ANALYSIS
    (Parlar Scientific Publications (P S P), 2021) Basbag, Mehmet; Sayar, Mehmet Salih; Cacan, Erdal; Karan, Halil
    The study was conducted to determine quality traits of some concentrate feedstuffs. For this purpose, commonly used eight concentrate feedstuffs samples were subjected to laboratory analyzes with three replications. According to the analysis results the means of investigated traits were ranged as follow; dry matter contents (DM) 87.29-92.13%, crude ash contents (CAC) 1.57-7.21%, organic matter contents (OM) 81.35-89.01%, crude protein contents (CP) 7.07-45.94%, crude oil contents (CO) 0.89-9.07%, crude cellulose contents (CS) 3.40-39.50%, metabolic energy values (ME) 3112.1-3265.3 kcal/kg, nitrogen-free extract (NFE) 28.50-72.95%, calcium contents (CA) 0.20-1.48%, magnesium contents (MG) 0.02-0.37%, phosphor contents (P) 0.27-0.50%, potassium contents (K) 0.36-2.60%, acid detergent fiber (ADF) contents 9.12 - 44.03%, neutral detergent fiber (NDF) contents 11.12-62.88%, digestible dry matter (DDM) contents 54.60-80.24%, dry matter intake (DMI) 1.91-13.16% and relative feed value (RFV) values 80.77-809.68. Additionally, biplot analysis revealed that there were positive relationship among ADF, NDF, CS, CO and DM traits. Accordingly; safflower meal (1) and cottonseed meal (2) went ahead for these traits. Similarly, positive relationship was determined among ME, RFV, DDM, DMI, NFE and K traits. Exclusively, the ground corn grain (3) was found superior for the important traits, so it was found as having best quality feedstuff.

    THE EFFECT OF DIFFERENT CUTTING TIMES ON FORAGE QUALITY TRAITS OF ALFALFA (Medicago sativa L.) GENOTYPES AND EVALUATIONS WITH BIPLOT ANALYSIS
    (Parlar Scientific Publications (P S P), 2022) Sayar, Mehmet Salih; Basbag, Mehmet; Cacan, Erdal; Karan, Halil
    This study was conducted to determine the effect of different cutting times on the forage quality traits of twenty-four alfalfa (Medicago sativa L.) genotypes. For this reason, a field trial was established according to separated plots in randomized blocks design with three replications in ecological conditions of Diyarbakir province, Turkey, in 2020. The three plant maturity stages were determined as cutting times. These stages were respectively the pre-flowering, 10% flowering and full flowering periods of alfalfa genotypes. Results of the study revealed that statically highly significant (P<0.01) differences were determined among the cutting times for all of the investigated traits. And the investigated traits had ranges as follow among the cutting times and the alfalfa genotypes; dry matter content (DM) 22.33-31.36%, crude protein content (CP) 14.67-25.87%, acid detergent fiber (ADF) content 25.77-44.10%, neutral detergent fiber (NDF) content 35.40-51.27%, digestible dry matter (DDM) content 54.55-68.85%, dry matter intake (DMI) 2.34-3.40%, metabolizable energy (ME) 8.09-10.84 MJ/kg DM and relative feed value (RFV) 98.98-181.26. Additionally, it was determined that digestibility and consumption status of alfalfa forages decreased with delaying of cutting times. Biplot analysis revealed that when all of the forage quality traits and forage dry matter content were evaluated together, 2nd cutting time, 10% flowering period, was determined as the most appropriate forage harvesting time for alfalfa genotypes. It also showed that there were highly significant (P<0.01) and positive relations among CP, DDM, DMI, ME and RFV traits, and Iside (16), Emiliana (9), Elci (8) and Bilensoy (3) alfalfa cultivars came to fore in terms of the five important forage quality traits.

    IDENTIFICATION OF CERTAIN AGRICULTURAL TRAITS AND INTER-TRAIT RELATIONSHIPS IN THE HELIANTHEMUM LEDIFOLIUM (L.) MILLER VAR. LASIOCARPUM (WILLK) BORNM.
    (Pakistan Botanical Soc, 2018) Basbag, Mehmet; Cacan, Erdal; Sayar, Mehmet Salih; Karan, Halil
    This study was conducted to determine certain plant traits and inter -trait relationships in the Helianthemum ledifolium (L.) Miller var. lasiocarpum (Willk.) Bornm. which is grown naturally in the protected area at the campus of Dicle University in 2015 and 2016. Two-year average of the research showed that the plant height was 30.04 cm, the number of main stem per plant was 1.02, the main stem diameter was 1.24 mm, the number of branch per plant was 1.06, the capsule number per plant was 4.04, the capsule diameter was 7.21 mm, the seed number per capsule was 158.5, the seed weight per capsule was 0.065 g, the thousand seed weight was 0.421 g, the seed yield per plant was 0.265 g and the germination rate was 0.5%. According to analysis results belonging to dry forage of the plant, the crude protein ratio was determined as 18.79%, ADF ratio as 26.23%, NDF ratio as 49.21%, calcium ratio as 1.14%, magnesium ratio as 0.04%, phosphor ratio as 0.42% and potassium ratio as 3.79%. The correlation analysis results showed that positive and highly significant relation was found between seed yield per plant and plant height, branch number per plant, capsule number per plant, number of seeds per capsule, seed weight per capsule traits. To increase seed yield in Helianthemum genotypes, exclusively that traits should be taken into account. Results of the study indicated that forage of Helianthemum ledifolium (L.) Miller var. lasiocarpum (Willk.) Bornm had sufficient digestibility and nutrient contents for livestock. But, it is recommended that new investigations should be carried out in order to determine the content of harmful substances in the forage of these plants for safely using the forages in the livestock feeding.
