CHANGES IN SEASONALLY MINERAL CONTENT OF Calligonum polygonoides L. SHRUB AND ITS CAPACITY OF MEETING DAILY MINERAL REQUIREMENTS OF GRAZING SMALL RUMINANT

Suleyman TEMEL

Abstract

 

Phog (Calligonum polygonoides L.) is widely grown in arid Igdir-Aralık wind erosion site and is an alternative feed source for grazing small ruminant (sheep and goat) in terms of its yield and quality. However, there are no studies on the mineral content during the plant’s active growth period. Our aim is to determine the macro and micro mineral contents during plant’s development and to check whether it meets with the daily mineral requirements of small ruminant. The research was carried out in a protected-area in 2016 and 2017. Samples were taken from 20 selected shrub clusters for 7 months (April-October) at the 15th of each month. Results showed that mineral contents (except copper, zinc and manganese) differs as to months and phosphorus, potassium, calcium, magnesium, sodium, iron, copper, zinc and manganese contents ranged between 0.33- 0.63%, 1.45-2.03%, 1.32-1.81%, 0.65-0.99%, 0.20-0.30%, 99.73-190.43 ppm, 2.00-2.67 ppm, 24.77-31.83 ppm and 34.16-45.56 ppm, respectively. According to these findings, phosphorus, potassium, calcium, sodium, iron, zinc and manganese contents of plant can sufficiently meet the daily requirements of small ruminant while copper content is not enough for the daily requirement. On the other hand, magnesium content was detected to be higher than the recommended level.

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
