    PLANTING DENSITIES IMPART VARIANCE IMPACT ON KERNEL PROPERTIES AND SOME QUALITY PARAMETERS IN SOME MAIZE (ZEA MAYS L.) HYBRIDS
    (Pakistan Botanical Soc, 2022) Konuskan, Omer; Konuskan, Dilsat Bozdogan; Barutcular, Celaleddin; Turan, Nizamettin; Elsabagh, Ayman
    Climate change scenario has revitalized necessity to optimize agronomic management practices for boosting cereals productivity and nutritional quality. To observe the growth and quality attribute of maize hybrids under various planting densities and in order to sort out the most suitable plant population, a field experiment was conducted at the Research Farm, Faculty of Agriculture, Mustafa Kemal University during 2018. Six maize hybrids viz. DKC 6589, Carella, Pioneer 1921, 70 May 82, Cadiz and Bolson were grown using five planting densities (9, 10, 11, 12, and 13 plants m2). The experiment was laid out in split plot arrangement with three replications. Maize hybrids and planting densitides were placed in main plots and sub plots, respectively. Growth characteristics like ear length, weight and diameter, and quality trauts like protein, stach and oil content in grains were determined as response variables. The results revealed that increasing plant densities gradually reduced the growth paramters including ear length, weight and diamter. While, quality traits such as starch and oil contents of basal, middle and tip kernels were increased with the increase in plant densities, but the protein ratio was decreased. The genotypes mean values indicated that 70 May 82 and Carella remained superior for ear length, weight and ear dimater respectively. In contrast, Pioneer 1921 and Bolson outformed other hybrids as far as starch and oil contents were concerned.

    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.
