The Line × Tester method was used to evaluate 10 inbred lines of field corn for grain yield and other yield-related traits. The experiment was conducted in a randomized complete block design with three replications. The results showed significant differences among the inbred lines and their crosses for all traits evaluated. The inbred lines and their crosses with the testers were ranked based on their performance for grain yield and other traits. The results of this study can be used to identify promising inbred lines and their crosses for further breeding programs. The Line × Tester method is widely used to evaluate the performance of inbred lines and their crosses for various traits of interest in plant breeding programs. In this study, we assessed 10 inbred lines of field corn using the Line × Tester method. Two testers were used to generate a series of hybrids, which were then evaluated for grain yield and other yield-related traits. The results showed significant differences among the inbred lines and their hybrids for grain yield, ear length, kernel depth, and other traits. The inbred lines and hybrids were ranked based on their performance, and the top-performing genotypes were identified. This study provides valuable information for the development of new corn varieties with improved yield potential and other desirable traits. The Line × Tester method is a useful tool for evaluating inbred lines and their crosses in plant breeding programs, and it can contribute to the development of new and improved crop varieties.

In this article, the diversity of land molluscs of Kohitang was studied. Malacafauna with 4 species belonging to 3 genera were described in the Kohitang mountain range and explored the unexploited lands of desert hilly mountain regions

The objective of this study was to investigate the effects of nitrogen fertilizer rate and plant density on straw, seed yield, and quality of three Linum usitatissimum L. cultivars. The study was conducted in a randomized complete block design with three replicates. The cultivars used were Linola 947, Linola 989, and CDC Bethune. Nitrogen fertilizer rates used were 0, 45, 90, and 135 kg/ha, while plant densities were 100, 200, and 300 plants/m2. The results showed that increasing nitrogen fertilizer rate significantly increased the straw yield, seed yield, and oil content of all cultivars. However, the increase in nitrogen fertilizer rate had a negative effect on protein content. Increasing plant density significantly decreased the straw yield, but significantly increased the seed yield and protein content of all cultivars. Oil content was not significantly affected by plant density. Linola 989 had the highest straw yield, seed yield, and oil content among the three cultivars. CDC Bethune had the highest protein content.

This article describes the most important diagnostic tests in determining protein metabolism disorders of Fish and their importance. When diagnosing disorders of protein metabolism in fish, it is necessary to carry out an analysis of feeding them according to age (nutritional norms), characteristic clinical signs (loss of appetite, development of coxexia, lag behind growth and development), pathologoanatomic changes (accumulation of fat around internal azos, darkening of body color, coxexia, blood clots in the intestines), morphobiochemical changes in the blood (hemoglobin, erythrocyte count, average of hematocrit, leukocyte count, neutrophil with Rod nucleus, basophils, monocytes, lymphocytes, analysis of the average total protein, total calcium, inorganic phosphorus and retinol) is considered important.

Garlic (Allium sativum L.) is an important crop that is widely cultivated for its medicinal and culinary properties. The growth and yield of garlic are influenced by various factors, including planting time and planting system. This study aimed to investigate the effect of planting time and planting system on the growth and yield of selected garlic germplasm. The study was conducted in a randomized complete block design (RCBD) with a factorial arrangement. The results of the study showed that planting time and planting system significantly influenced the growth and yield of garlic germplasm. Early planting and raised bed planting were found to be the most effective practices in enhancing the growth and yield of garlic germplasm. These findings suggest that farmers should consider these practices to maximize their garlic production.
