Genetic variability and selection are crucial for finger millet breeding programs to maximize genetic gain and productivity. This study evaluated 18 finger millet landraces cultivated in the mid-hills of Nepal, along with ‘Kavre Kodo 2’ as a check variety, assessing 14 agro-morphological traits. The objective was to identify superior finger millet landraces using a multivariate approach based on the multi-trait genotype– ideotype distance index (MGIDI). The experiment was conducted in a randomized complete block design (RCBD) with three replications. Principal component analysis revealed that the first five components collectively accounted for 80.8% of the total variation, reflecting the genetic relatedness …

Seed priming is a critical pre-sowing strategy to enhance germination and early seedling vigour under diverse environmental conditions. This study evaluated the effects of various priming agents, including Boric acid, DAP, CaCO3, FeCl2, Urea, PEG (5%), CuSO4, MOP, PEG (10%), and ZnSO4, on germination parameters-germination percentage (GP), germination speed (GS), germination energy (GE), and vigour index (VI)-across rice, wheat, and maize varieties. A two factorial experiment was conducted using a completely randomized design, with ANOVA revealing significant effects (p < 0.001) of variety, treatment, and their interaction on germination traits. The results demonstrated that FeCl2 significantly improved germination in rice, particularly for the BRRI Dhan-66 variety, while CaCO3 and PEG treatments showed varying efficacy across crops. In wheat, the Bijaya variety exhibited superior performance with CaCO3 treatment, whereas DAP was more effective for Banganga. Maize showed the highest germination rates overall, with Sundarharaicha-LR1 responding positively to ZnSO4 and boric acid. Correlation and PCA analyses highlighted strong interdependence among germination traits, with GS and GP emerging as robust indicators. Varietal clustering in PCA revealed genetic variability in response to priming agents. This study provides valuable insights into optimizing priming techniques for enhancing seed performance in cereals. The findings emphasize the importance of tailored priming strategies based on crop species and variety to maximize agricultural productivity.

Soil is a fundamental part of successful agriculture, and its quality has to be improved to maximize crop yield and soil fertility. To increase crop productivity and soil fertility, biochar can be applied to the soil. Biochar is a solid carbon-rich product produced from biomass of agricultural crop residues, wastes, and wood, through pyrolysis in an oxygen-deficient condition. Carbon sequestration through biochar is important because of its potential applications in recycling wastes, retaining nutrients in the soil and lowering greenhouse gas emissions. In this review, we explore the various applications of biochar to ensure the safe and sustainable …

Global food shortages are caused mainly by drought, the primary driver of yield loss in agriculture worldwide. Drought stress negatively impacts the physiological and morphological characteristics of rice (Oryza sativa L.), limiting the plant productivity and hence the economy of global rice production. Physiological changes due to drought stress in rice include constrained cell division and elongation, stomatal closure, loss of turgor adjustment, reduced photosynthesis, and lower yields. Morphological changes include inhibition of seed germination, reduced tillers, early maturity, and reduced biomass. In addition, drought stress leads to a metabolic alteration by increasing the buildup of …

As digitalization increasingly gains attention in the agriculture sector, many African youths are seizing the opportunity provided by digital technologies to engage in agriculture. While prior studies have started examining the intricacies of digitalization in agriculture, they have paid less attention to its implications for fostering institutions and inter-organizational synergies that can support and sustain the businesses of youth enterprises engaging with Africa’s agriculture. Against this backdrop, we undertook a qualitative case study to shed light on the development of a community of practice comprising youth enterprises engaging in agriculture through digitalization. Thus, we studied Africa Goes Digital (AFGD), a …

Box Tree Moth (Cydalima Perspectalis), Kripa Dhakal, Karla M. Addesso

Extension Publications

The box tree moth (BTM), Cydalima perspectalis (Walker) (Lepidoptera: Crambidae), is an invasive pest of boxwood (Buxus spp.) causing severe damage to these popular ornamental plants. These plants are popular for their low maintenance, deer resistance, and evergreen foliage. It is a shrub common to almost all landscape environments in the United States. The box tree moth is native to East Asia. It was discovered in Europe in 2007, and since then it has spread rapidly across the continent. In 2018, box tree moth was first detected in North America in Ontario, Canada and in July 2021, the U.S. Department …

Japanese beetle (Coleoptera: Scarabaeidae), Popillia japonica Newman, is an invasive beetle introduced from Asia to the United States in the early 1900s. It was first detected in New Jersey and later distributed in 28 states in the United States (Fig 1). In Tennessee, the beetle population was first detected in 1936, and about 80 counties in Tennessee have been infested by their establishment. Adult beetles feed on over 300 plant species, including foliage, fruits, and flowers. It is a significant pest of turfgrass, and ornamental and horticultural crops in the eastern United States. Adults and larvae aggregate on the plants …
