To help farmers in the mid hills of Nepal improve their crop management and rice yields, we conducted a study testing different nursery management options and their effect on grain yield and yield components under rainfed conditions. The experiment was conducted in a farmer’s field during the cropping season 2009 and 2010 at Sundarbazar, Lamjung, Nepal, using a 3-factor factorial RCB design wit...

Water and salinity stresses are the major environmental concerns limiting crop production, particularly in arid semi-arid ecologies. Focused research is required to develop mitigating strategies manage such stresses. Application of plant-bioregulators (PBRs) may be an effective option water Therefore, a field experiment was conducted during 2016–17 2017–18 at saline site NW (north-western) Indi...

Perennial ryegrass is one of the most commonly cultivated forage species in Europe, where grazing and mowing (cutting) are used to manage this resource. Cutting can be characterized by its intensity (height) and its frequency. Combinations of these two factors affect mono-species grasslands productivity and could also modify the genotypic composition of heterogeneous populations. Indeed, the hi...

The research was applied at Station No. 1 belonging to the College of Agriculture, University Anbar, determine most appropriate traits for improving barley grain yield during season 2021-2022 by designing randomized complete blocks in split plots with three replications, purpose studying path way coefficient and its components five cultivars (Samir , Aksad 617, Amal, Buraq Abba 265) seed rates ...

Before selecting genotypes for nutritional quality characters (protein, oil and micronutrients content) and anti-nutritional factor (phytic acid), it is important to know how much selection is likely to affect yield. Using a diverse range of genotypes, relationships between quality traits with yield and yield attributes in pearl millet were investigated. The number of productive tillers, panicl...

This study was conducted to examine the variabilities in the chronology of vegetative and reproductive development of weedy rice (Oryza spp.) in comparison with commercial varieties. Data at different growth stages of 14 weedy rice morphotypes and 4 commercial rice varieties were recorded and analysed. Plant height of all weedy rice morphotypes were observed to be significantly higher compared ...

Seedling roots enable plant establishment. Their small phenotypes are measured routinely. Adult root systems are relevant to yield and efficiency, but phenotyping is challenging. Root length exceeds the volume of most pots. Field studies measure partial adult root systems through coring or use seedling roots as adult surrogates. Here, we phenotyped 79 diverse lines of the small grass model Brac...

A potential pest of switchgrass, Panicum virgatum L., was first detected in South Dakota in 2004, where death of partially emerged leaves was noted in a small proportion of tillers. Similar “dead heart” symptoms were observed in switchgrass in Illinois during 2008 and adults of a stem-boring caterpillar were collected and identified as Blastobasis repartella (Dietz). In 2009, a survey of the ce...
