Effect of Pre-harvest Application on Physical Attributes of Guava (Psidium guajava L.) in cv. L–49: Plant Growth Regulators and Bagging

The present investigation was conducted to study the Effect of pre-harvest application of plant growth regulators (PGR) and bagging on Physical attributes of Guava (Psidium guajava L.) in cv. L - 49. The research was carried out at the main experiment station Horticulture, Department of Fruit Sciences, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Ayodhya 224229 (U.P.) India during the year 2022-23. The experiment was conducted in a Randomized Block Design with three replications and 8 treatments GA3 (50 ppm) and NAA (20 ppm) and GA3 (50 ppm) +NAA (20 ppm), GA3 (50 ppm) with bagging, and NAA (20 ppm) with bagging. GA3 (50 ppm) + NAA (20 ppm) with bagging, bagging (white polythene), and control applied on spray 45 days before harvesting. It is concluded that among the different treatments. T6 GA3 (50 ppm) + NAA (20 ppm) with bagging, was recorded maximum Fruit length (4.90 cm), Fruit width (6.62 cm), Fruit weight (158.20 gram), Fruit volume (161.60 cm3), Specific gravity (0.98 g/cm3) therefore, recommended for application to the Guava tree in the sub-tropical region of Uttar Pradesh in order to obtain better quality fruit.

Genome Sequencing in Field Crops: Unlocking Agricultural Potential

Genome sequencing has revolutionized agriculture by providing crucial insights into the genetic make-up of field crops. This paper explores the importance of genome sequencing in unlocking the agricultural potential of various field crops. By sequencing the DNA of crops such as wheat, maize, rice, and soybean researchers are gain a comprehensive understanding of their genetic diversity, disease resistance and yield-enhancing traits. This knowledge enables the development of precision breeding strategies, leading to the creation of high-yielding, stress-tolerant and nutritionally enhanced crop varieties. In addition, genome sequencing is facilitating the identification of key genes involved in plant-microbe interactions and adaptation to environmental stressors. Such knowledge can inform sustainable agricultural practices, reduce chemical inputs and increase crop resilience in the face of climate change. This paper highlights the transformative impact of genome sequencing on crop improvement, food security and global agricultural sustainability.
