“…Grain yield was negatively correlated with AUDPC (-0.17322) which means, grain yield decreases with increase in AUDPC value (Table 1). This result in accordance to findings of Kandel et al (2014), Tewari et al, (2016) and Lamsal et al, (2017). This may be because of reduced photosynthetic area of the plant to assimilate the carbohydrate in seed due to the diseased leaf.…”

A field experiment was conducted to evaluate the performance of wheat genotypes against spot blotch disease from November 2016 to April 2017. Experimental field was designed in Alpha Lattice Design with 2 replications and 20 genotypes as treatments. Area Under Disease Progress Curve (AUDPC) value, days to heading, days to maturity, plant height, spike per m2, grain per spike, Thousand Kernel Weight (TKW), grain yield were examined. Negative correlation was observed between yield of different genotypes and AUDPC i.e. -0.17322. Genotype BL 4699 and NL 1247 were found to be resistant with AUDPC value 141.7 and 140.6 and yield 3.335MT/ha and 3.604MT/ha respectively. Similarly, genotype BL 4708, NL 1327 and BL 4707 were found to be tolerant with AUDPC value 567.2, 570.6 and 274.6 and yield 3.761MT/ha, 3.642MT/ha and 3.681Mt/ha respectively. So, resistant and tolerant genotypes BL 4699, NL 1247, BL 4708, NL 1327 and BL 4707 could be suggested to incorporate into the breeding program.

“…Significant negative correlation between AUDPC of foliage diseases and dry matter yield indicate negative impact of these diseases on herbage yield of improved Brachiaria cultivars. This might be attributed to the reduction of the photosynthetic area in the diseased leaf tissues as reported for wheat diseases (Kandel et al 2014;Lamsal et al 2017;Pandey et al 2018), as well as pathogen's dependence on host for nutrients and water. We observed significant and negative correlation between leaf rust and foliar blight and plant height conferring the negative effect of diseases on plant growth and development.…”

This is the final version of the article that is published ahead of the print and online issue Brachiaria (Urochloa) grass is one of the most important tropical forages distributed in the tropical and subtropical regions of eastern and western hemispheres (Renvoize et al. 1996). Brachiaria grass possess several characteristics of agricultural and environmental significance, such as high biomass yield, nutritious to livestock, drought and shade tolerance, soil fertility improvement, high nutrient use efficiency, mitigation of the climate change adversity and effective bioagents for pests and parasitic weed management (Subbarao et al. 2009;Maass et al. 2015;Khan et al. 2016). The genus Brachiaria consists of approximately 100 species, of which seven perennial species of African origin have been exploited for fodder production, and they have been cultivated in Asia, Australia, the South Pacific, and South America at various scales (Stür et al. 1996;Jank et al. 2014). Brachiaria species are a common and valuable constituent of natural vegetation in East Africa (Boonman 1993), but their use as sown pasture for animal production is very recent in the region (Maass et al. 2015;Njarui et al. 2016). A broad adaptation, excellent animal performances and high biomass yields are among the major factors that promote a wider and rapid adoption of Brachiaria grass across the tropics and subtropics. However, the productivity of Brachiaria grass is affected by different abiotic and biotic factors, including diseases causing high yield losses (Nzioki et al. 2016; Hernandez et al. 2017). Diseases of Brachiaria grass, their symptoms, geographical distribution, and management options have been reviewed by Valerio et al. (1996). These diseases have negative impact on livestock productivity, because they reduce forage yields and quality.Brachiaria grass is one of the preferred forages by livestock keepers in Rwanda and in other East African countries (Mutimura and Everson 2012;Maass et al. 2015). As mentioned earlier, diseases are among the major biotic constraints of Brachiaria grass production, and diseases, such as leaf rust, leaf spot, and leaf blight are reported to cause economic loss (Lenné and Trutman 1994;Miles et al. 1996;Rao et al. 1996;Alvarez et al. 2014;Maass et al. 2015). For instance, leaf rust can cause up to 100% yield loss, reduces leaf crude protein content to between 49 and 53% and subsides availability of other nutrients (Lenné and Trutman 1994). Similarly, leaf blight reduces forage biomass yield by approximately 50% in the tropics (Alvarez et al. 2013). Recent studies have shown widespread distribution of leaf rust, leaf spot, and leaf blight diseases in Kenya and Rwanda (Nzioki et al. 2016;Uzayisenga et al. 2020). Therefore, sustainability of Brachiaria grass production in Africa relies on how well these diseases are managed.Many pastures including Brachiaria grass are considered low-value crops, often cultivated in large acreage and management of diseases using chemical is too costly and

“…The application of 140 kg N/ha and 150 kg seed rate/ha was the best combination for getting higher seed yield with its better quality. Kandel et al, (2009) elucidated the role of nitrogen in wheat genotypes for management of the disease. Four doses of nitrogen in six different promising genotypes were tested.…”
