Wheat (Triticum aestivum L.) is the most widely adapted crop to various agro climatic conditions, consequently, has got a major place among the cereal crops in the world. In wheat development programs, the evaluation and identification of superior lines from introduced plant materials, is the first and leading step in a crop improvement program. The experiment was planted at Mountain Agricultural Research Center, Juglot, Pakistan during 2014-15 following randomized complete block design with three replications. The current research was carried out to evaluate 10 bread wheat accessions for yield and its associated characters. The analysis of variance, mean performance, correlation and cluster analysis were computed. The analysis of variance exhibited that all the genotypes performed significantly (P≤0.05) variable for plant height, days to flowering, days to 50% maturity, grain per spike, straw weight, Total grain weight, registering the significant genetic variability among the genotypes for further evaluation. With regards to mean performance, the AC-4, AC-6 and AC-8 showed better performance for various traits. Cluster analysis revealed two accessions AC-4 and AC-5 as most diverse among all members. So, these accessions can be further used in breeding programme to achieve better yield. Also molecular studies on these accessions can point out many novel gene sources in these accessions.

The present research work was conducted at the Germplasm Center, Department of Horticulture, Patuakhali Science and Technology University (PSTU), during 2018/2019. The experiment was laid out following a Randomized Complete Block Design (RCBD) with 15 germplasm (treatments) and 4 replications (blocks). The experimental germplasms were Mo-1 to Mo-15. There was found a significant variation among the germplasm in relation to leaf, flower and pod. Better results were obtained from germplasm Mo-2, 14 and 15 in respect of number of leaves, number of leaflets per leaf, leaf length, leaf width, pod length, pod width, seed width, fleshy material weight, yield/tree. Except Mo-1 and Mo-11, all the germplasm had three flowering peaks. Among 15 germplasm 10 of the germplasm produced white colored flower, 3 produced cream-colored flower and 2 produced cream-colored flowers with red streaks. Highest number of leaves (8.25) was recorded in germplasm Mo-2. Longest leaf length was found in Mo-15 (49.75cm) and width was in Mo-14 (21.87cm). Highest number of leaflets per leaf (434.8) was recorded in Mo-15. Maximum pod length (59.83cm) and width (1.8cm) was found in Mo-2. Longest seed length was found in Mo-6 (1.46cm) and width in Mo-15 (0.8cm). The highest number of seeds per pod (24.00) was found in both Mo-8 and Mo-5. The maximum 10-seed weight was found in Mo-9 (4.35 g). Highest fleshy material weight was found in Mo-2 (66.5 g). The maximum total fruit per plant (335.8) and yield (23.51kg) was found in germplasm Mo-2.

A study was conducted at Bina Sub-station Nalitabari, Sherpur Farm from June to October 2022 to investigatethe effect of combining organic and inorganic fertilizers on rice growth and yield. It followed a randomized block design with three replications and a unit plot size of 3m×4m.The experiment consisted of five treatments: T1 100% STB (N90P15K75S12Zn2), T2 (85% CF+ 5t/ha cow dung), T3 (85% CF+ 4t/ha vermicompost), T4 (70% CF+ 5t/ha cow dung), and T5 (70% CF+ 2t/ha vermicompost). The objective was to assess their impact on the growth, yield, and yield-contributing characteristics of the BINAdhan-17 rice variety. The study found that combining inorganic fertilizer with 2t/ha of vermicompost resulted in the highest yield. Chemical fertilizer (CF) with organic sources increased yield. The tallest plants were in T1 (104.9cm), while the shortest was in T4. The highest grain yield was in T3 (5.9t/ha), and lowest in T4 (4.7t/ha).When combining 4t/ha of vermicompost with 85% CF (77kg N, 13kg P, 64kg K, 12kg S, 2kg Zn), the parameters of tillers per plant, panicle length, filled grains per panicle, 1000-grain weight, grain yield, and straw yield were maximized.Based on these findings, it can be concluded that Using high-quality rice varieties and incorporating compost, alone or with chemical fertilizers, increases yields compared to full inorganic fertilizer. The study emphasizes the importance of judicious organic and chemical fertilizer application for significantly enhancing rice yields.
