    (Parlar Scientific Publications, 2020) Omar, Abd Elhamid Mohamed; Khalifa, Mohammed Abdelmonem; Elhity, Mahmoud Abdelhamid; Yousef, Mahmoud Ibrahim Abo; Kizilgeci, Ferhat; Ozturk, Ferhat; Islam, Mohammad Sohidul
    Gibberellic acid (GA3) plays a vital role in boosting hybrid rice yield, however, fresh research needs to be done for its dose optimization especially for newly developed hybrid rice lines. To fill this research gap, an investigation was conducted at the experimental farm of Sakha Agricultural Research Station, Kafrelsheikh, Egypt during two growing seasons of 2017 and 2018. The main objective of this study was to evaluate the impact of GA3 application on hybrid rice lines for boosting seed production. Egyptian hybrid No.l and G46 A/Giza 178 R were the hybrid rice lines, while GA3 in four doses viz. 0, 250, 300 and 350 g/ha were applied. The experimental design was split plot with three replications, where the main plot was devoted to hybrid rice lines, while the subplots had different doses of GA3. The results showed that the best desirable values for the studied characteristics especially for hybrid seed yield (2.5 t/ha) were recorded of the hybrid combination IR69625/Giza 178 followed by G46A/Gizal78 with the highest dose of GA3. It is concluded that foliage application of GA3@ 350 g/ha has the potential to enhance hybrid rice seed production, while hybrid rice line Giza 178 can be recommended for general adoption in the irrigated regions of Egypt. © PSP

    (Pakistan Botanical Society, 2020) Ahmad, Zahoor; Waraich, Ejaz Ahmad; Barutçular, Celaleddin; Alharby, Hesham; Bamagoos, Atif; Kizilgeci, Ferhat; Öztürk, Ferhat
    Considering the burning issue the present study was undertaken in pot culture at the Cholistan Institute of Desert Studies (CIDS), The Islamia University of Bahawalpur, Pakistan for enhancing drought tolerance in two oilseed crops (OC) crops camelina (Camelina sativa L.) and canola (Canola napus L.) through improving physiological, biochemical, and antioxidants activity by foliar application of selenium (Se) under drought stress. Two Camelina (i.e., ‘Australian Camelina’ and ‘Canadian Camelina’) and canola genotypes (i.e., ‘AARI Canola’ and ‘UAF Canola’) were used as plant materials during the growing season of 2016. Both Camelina and Canola genotypes were grown under normal (100% FC) and water deficit (drought stress) (40% FC) conditions. Four levels of Se: such as seeds priming with 75?M Se, foliar application of Se at 7.06 ?M and foliar Se in combination with seeds priming (7.06 ?M & 75?M) along with control were applied at the vegetative stage of both OC crops for screening drought tolerant genotypes. All treatments were arranged three times in a randomized complete block design. Both OC crops were grown upto the maturity and data on physiochemical, antioxidants and yield components were recorded during this study. Results of the present study indicated that the physio-biochemical parameters such as WP (water potential), OP (osmotic potential), TP (turgor pressure), proline, TSS (total soluble sugar), TFAA (total free amino acids), TPr (total proteins) and TS (total sugars); and total chlorophyll contents were improved by foliar application Se along with seed priming by Se in both OC crops in both drought stress and non-stress (control) conditions. Similarly, osmoprotectants such as GB (Glycinebetaine), anthocyanin, TPC (total phenolic contents) and flavonoids; as well as antioxidants such as APX (ascorbate peroxidase), SOD (superoxide dismutase), POD (peroxidase) and CAT (catalase) were also showed better enhancement in both OC crops through foliar application in combination with seed priming with Se (7.06 ?M & 75?M) under normal as well as water deficit (drought) conditions. Yield and its components i.e., branches plant-1 (no.), 1000-seed weight (g), seed and biological yield (t ha-1) of both OC crops were increased through foliar application in combination with seed priming by Se (7.06 ?M & 75?M) under drought and non-drought stress conditions. Both camelina and Canola genotypes categorized based on all the above-mentioned parameters under the water deficit (drought stress) condition and foliar application of Se, the genotype ‘Canadian Camelina’ maintained the highest values for all these attributes. Therefore, it is revealed that foliar application in combination with seed priming by Se helps to improve drought tolerance of OC crops and also leads to an increase in the productivity of crops under drought stress. Among the genotypes, ‘Canadian Camelina’ performed the best when seeds of the genotypes were primed with Se in combination with foliar application of Se at the vegetative stage. © 2020, Pakistan Botanical Society.

    EVALUATING SHORT STATURE AND HIGH YIELDING MAIZE HYBRIDS IN MULTIPLE ENVIRONMENTS USING GGE BIPLOT AND AMMI MODELS
    (Soc Field Crop Sci, 2020) Ahmed, Asgar; Hossain, Akbar; Amiruzzaman, Md; Alam, Md Ashraful; Farooq, Muhammad; El Sabagh, Ayman; Kizilgeci, Ferhat
    In Bangladesh, maize stands second place after rice; since it faces diverse natural calamities during its highest growing season (rabi/winter), particularly strong storm during the reproductive stage. Sometimes in some regions, this crop is completely damaged by natural disasters. Considering the burning issue, thirteen hybrids, including 10 previously selected short stature hybrids were evaluated against three local and standard checks: 'BHM-9', '981' and 'Sunshine' in two consecutive years in seven locations of Bangladesh. Combined analysis over locations and seasons instigated that genotypes 'Sunshine', '981' and 'G10' were the top-high yielders, while genotypes 'G1', 'G2', 'BHM-9' and 'Sunshine' were found the most stable. On the other hand, five genotypes such as 'G3', 'G4', 'G6', 'G8' and 'G9' had the below-average mean yield and the genotypes 'G6' and 'G9' were the most unstable. Among the seven environments, Jamalpur, Joydebpur and Dinajpur were most discriminating and Ishwardi was the least discriminating; whereas Joydebpur was more representative and Borishal was the least representative of other test environments. In the case of plant and ear height, most of the genotypes showed a lower value than all the checks, which was desirable. But among the top three high yielders, local cross-genotype, the 'G10' had the lowest and more stable value for both plant height and ear height. Therefore, considering the plant and ear height, grain yield, and yield stability, the genotype 'G10' has been recommended for release as commercial variety and has been released as new maize variety in Bangladesh with the local name of 'BARI Hybrid Maize-16' (BHM-16).

    Normalized Difference Vegetation Index and Chlorophyll Content for Precision Nitrogen Management in Durum Wheat Cultivars under Semi-Arid Conditions
    (Mdpi, 2021) Kizilgeci, Ferhat; Yildirim, Mehmet; Islam, Mohammad Sohidul; Ratnasekera, Disna; Iqbal, Muhammad Aamir; Sabagh, Ayman E. L.
    To impart sustainability to modern intensive farming systems, environmental pollution caused by nitrogenous fertilizers in needs to be reduced by optimizing their doses. To estimate the grain yield and nutrtional quallity of wheat, the normalized difference vegetation index (NDVI) and chlorophyll content (SPAD) are potential screening tools to identify the N deficiency and screen out the promising cultivars. The two-year field study was comprised with five levels of nitrogen (N) (control, 50, 100, 150 and 200 kg N ha(-1)) and two durum wheat genotypes (Sena and Svevo). The experimental design was split-plot, in which N levels were placed in the main plots, while wheat genotypes were arranged in sub-plots. To predict the yield and quality traits, the NDVI and SPAD values recorded at heading, anthesis and milky growth stages were taken as response variables. The results revealed that N fertilization significantly influenced the SPAD and NDVI attributed traits of durum wheat, except NDVI at milky stage (NDVI-M) during the first year. The maximum value of NDVI was recorded by 150 kg N ha(-1), while control treatment gave the minimum value. The grain yield was increased with the increasing dose of the N up to 100 kg N ha(-1) (4121 kg ha(-1)), and thereafter, it was declined with further increased of N levels. However, the variation between the genotypes was not significant, except NDVI and SPAD values at the milky stage. The genotype Svevo had the highest NDVI values at all growth stages, while the genotype Sena recorded the maximum SPAD values during both years. Similarly, the N levels significantly influenced the quality traits (protein, wet gluten, starch test weight and Zeleny sedimentation) of both genotypes. The highly significant relationship of SPAD and NDVI with the grain yield and yield attributes showed their reliability as indicators for determining the N deficiency and selection of superior wheat genotypes for ensuring food security under climate change scenario.

    YIELD AND GRAIN PROTEIN OF WHEAT (TRITICUM AESTIVUM L.) IS INFLUENCED BY THE APPLICATION OF DIFFERENT LEVELS OF NITROGEN
    (Parlar Scientific Publications (P S P), 2020) Jahan, Abu Hena Sorwar; Hossain, Akbar; Alam, Nur; Ali, Ahsan; Saif, Hasib Bin; Kizilgeci, Ferhat; Konuskan, Omer
    Malnutrition is one of the major problems in the poor people of Bangladesh. There are some reports that additional nitrogen (over than recommended does) application to wheat plants result in more protein content in wheat grain. To justify these phenomena; the experiment was conducted in consecutive two years (2015-16 and 2016-17) at two locations (Gazipur and Dinajpur) during rabi season (November to March each year). There were used six nitrogen (N) treatments, such as 0, 100, 125, T-3; 150, 175 and 200 kg N hat. In the study, wheat cultivated at Dinajpur location exhibited more spikes m(-2), spike length, spikelets spike(-1), grains spike(-1), 1000-grain weight and higher grain yield in both years than Gazipur location. Considering combined N levels over the locations, the highest grain protein (14 %) as well as grain yield (5.00 t ha(-1)) was estimated when 200 kg N ha(-1) was applied. In economics point of view, 200 kg N ha(-1) application also gave the maximum (BCR, 1.21) followed by 175 kg N ha(-1) (1.20) and 150 kg N ha(-1) 1.20). Whereas, the maximum MBCR was found in 100 kg N ha(-1) (15.63). Therefore, to minimize malnutrition severity among the children as well as adult people in the developing countries like Bangladesh, 175 or 200 kg N ha(-1) may he applied in wheat to increase percentage protein in wheat grain.
