Abstract: Field tests were conducted by the Agricultural research field at Patuakhali Science and Technology University from January to June 2018 to examine the effects of variety and plant spacing on yield. The experiment included three hybrid varieties: Pioneer-3396, Titan, Sunshine, and three spacing of plant: (70 X 15) cm2, (60 X 20) cm2 and (50 X 25) cm2. The experiment created with a randomized complete block design with three replicates. Results showed a significant impact of the variety and spacing on yields and yields examined. Maximum rows cob-1, seeds row-1, cob breadthm, cob weight, stems girth, and grain yield were recorded from the hybrid variety Titan. Maximum number of cob plant-1, seeds row-1, seeds cob-1, highest cob length, cob weight, grain weight cob-1, grain yield, and straw yield were recorded in spacing (60 X 20) cm2. In contrast, (50 X 25) cm2 spacing produced minimum values of the above-mentioned plant parameters also lowest grain and straw yield. Interaction effects of variety and spacing, showed the maximum seeds Cob-1 (339.0), the highest cob (13.52 cm), the maximum cob weight (129.7 g), and grain weight Cob-1 (104.7 g) with titanium. Significant 1000 seed weight (272.7 g) recorded with Titan. At (60 X 20) cm2 intervals, maximum grain yield (9.0 tha-1) and straw yield (4.2 tha-1). Minimum outputs were recorded at Pioneer 3396 with closest plant distance of (70 X 15) cm2. Because of experimental results, we can conclude that corn (CV. Hybrid-Titan -Corn) can be grown with a distance of (60 X 20) cm2 for the highest income.

Abstract: Fusarium wilt, caused by Fusarium oxysporum f. sp. ciceris, is a major constraint to chickpea production worldwide, resulting in substantial yield reduction and deterioration of crop quality. The effectiveness of host resistance is often challenged by the emergence of new pathogen races, necessitating the continuous identification of resistant germplasm for breeding programs. This study was conducted to identify chickpea genotypes with resistance to Fusarium wilt and to select promising materials for further breeding. A total of 47 chickpea genotypes, along with two standard checks (Geletu and Dimtu), were evaluated under field conditions during the 2022 and 2023 main cropping seasons using an augmented experimental design. Disease incidence was recorded at both seedling and flowering stages, and genotypes were classified according to the ICRISAT disease rating scale. Considerable variation in disease response was observed among the tested genotypes. Two genotypes exhibited resistant reactions, while seventeen were categorized as moderately resistant. Overall, nineteen genotypes demonstrated desirable levels of resistance and were identified as valuable sources of resistance for future chickpea improvement programs. These genotypes can be advanced to subsequent breeding stages for the development of Fusarium wilt-resistant chickpea varieties.
