Öğe DISCRETIZATION OF THE METHOD OF GENERATING AN EXPANDED FAMILY OF DISTRIBUTIONS BASED UPON TRUNCATED DISTRIBUTIONS(Vinca Inst Nuclear Sci, 2021) Farooq, Muhammad; Mohsin, Muhammad; Naeem, Muhammad; Farman, Muhammad; Akgul, Ali; Saleem, Muhammad UmarDiscretization translates the continuous functions into discrete version making them more adaptable for numerical computation and application in applied mathematics and computer sciences. In this article, discrete analogues of a generalization method of generating a new family of distributions is provided. Several new discrete distributions are derived using the proposed methodology. A discrete Weibull-Geometric distribution is considered and various of its significant characteristics including moment, survival function, reliability function, quantile function, and order statistics are discussed. The method of maximum likelihood and the method of moments are used to estimate the model parameters. The performance o f the proposed model is probed through a real data set. A comparison of our model with some existing models is also given to demonstrate its efficiency.Öğe 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, FerhatIn 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).Öğe Morphological, Physiobiochemical and Molecular Adaptability of Legumes of Fabaceae to Drought Stress, with Special Reference to Medicago Sativa L(Springer Singapore, 2020) Hossain, Akbar; Farooq, Muhammad; Sabagh, Ayman El; Hasanuzzaman, Mirza; Erman, Murat; Islam, TofazzalDrought stress (DS) is one of the most hostile limitations for sustainable crop production. Developing DS-tolerant crop cultivars and the use of better crop management practices may help improve crop performance under drought. In this chapter, the adverse effect of drought on the growth and development of legumes and the morphological, physiobiochemical, and molecular basis of adaptability to drought are described. Under drought, overproduction of reactive oxygen species causes oxidative damage. The role of osmolytes and antioxidants in countering the oxidative damages has been widely described. Moreover, “omics-based approaches, ” such as proteomics, metabolomics–transcriptomics, and genomics are promissory approaches to identify drought-tolerant genes, decode complex gene networks, and numerous signaling cascades involved in drought tolerance in legumes. The recently developed CRISPR-Cas technology has already been used in precision breeding of many plants including the members of Fabaceae such as alfalfa is also discussed in the chapter. © Springer Nature Singapore Pte Ltd. 2020.Öğe PHENOLOGY, GROWTH AND YIELD ARE STRONGLY INFLUENCED BY HEAT STRESS IN LATE SOWN MUSTARD (BRASSICA SPP.) VARIETIES(Pakistan Botanical Soc, 2020) Bazzaz, Md Mahfuz; Hossain, Akbar; Farooq, Muhammad; Alharby, Hesham; Bamagoos, Atif; Nuruzzaman, Md; Khanum, MahbubaIn rice-based cropping system of northern Bangladesh, mustard planting is delayed due to late harvest of monsoon rice (Transplanted Aman rice; T. Aman rice). The late sown mustard is often exposed to high-temperature stress during the reproductive stage, which causes a significant decrease in seed yield. Most of the farmers plant a low yielding local mustard variety 'Tori-7', which is sensitive to high-temperature stress. The Oil Seeds Research Centre of Bangladesh Agricultural Research Institute has recently released short duration and high-yielding mustard varieties for the rice-based cropping system of northern Bangladesh to tackle this issue. However, the performance of these varieties in the target cropping system under late sown conditions (together with exposure to heat stress) has not been evaluated yet. Therefore, this two-year field experiment was conducted to assess the performance of newly released mustard varieties 'BARI Sarisha-14' and `BARI Sarisha-15' in comparison with the local check variety 'Tori-7' sown at five planting dates (viz. October 21, November 1, November 10, November 20, and November 30). The delay in sowing shortened time (days) to flowering and maturity, regardless of the variety. Similarly, plant height, branches/plant and total dry matter accumulation of the tested varieties were also reduced upon delay in planting. The greatest seed yield was observed in varieties `BARI Sarisha-15' and `BARI Sarisha-14' when sown on October 21. These two varieties produced fair seed yield when sown at November 20. However, the local variety 'Tori7' yielded the least across all the planting dates. Therefore, the varieties `BARI Sarisha-14' and `BARI Sarisha-15' may be planted in the rice-based cropping system of northern Bangladesh after harvest of T. Aman rice to get maximum seed yield.
