Fungal pathogens exert severe qualitative and quantitative damages to wheat crop. Karnal bunt of wheat caused by Tilletia indica Mitra, Mundkur is a severe threat to global food security. Nonetheless, T. indica is regulated as a quarantine pest in numerous countries, which further aggravates the situation. Tolerant varieties and appropriate management practices for Karnal bunt are imperative to meet the global wheat demands. This two-year study explored the impact of fungicide [Fosetyl-Aluminium (Aliette)] application timing on allometric traits, disease suppression and economic returns of bread wheat. Four bread wheat cultivars differing in their tolerance to Karnal bunt were used in the study. Fungicide was applied as either seed treatment (ST), foliar application at heading (FAH) or ST + FAH, whereas no application (NA) was taken as control. Lasani-08 performed better than the rest of the cultivars in terms of allometric traits (plant height, leaf area, crop growth rate, photosynthesis, and chlorophyll content), yield and economic returns. Nonetheless, minimal disease severity was recorded for Lasani-08 compared to other cultivars during both years. The ST improved allometric traits of all cultivars; however, ST + FAH resulted in higher yield and economic returns. Cultivar Pasban-90 observed the highest disease severity and performed poor for allometric traits, yield and economic returns. It is concluded that ST + FAH of Fosetyl-Aluminium could be a pragmatic option to cope Karnal bunt of wheat. Nonetheless, Pasban-90 must not be used for cultivation to avoid yield and quality losses.

“…As reported by several investigators, zinc has beneficial effects on tillering (Alloway, 2008), fertility and grain formation (Fageria, 2009) and grain weight, through increasing photosynthesis and dry matter production (Abou Khalifa and EL-Rewainy,2012), and consequently increase grain yield. These findings were in agreement with those reported by Dhakad et al (2020), andHuang et al (2020).…”

“…Delaying of sowing resulted in decreasing number of effective tillers/m2, number of grains/panicle and 100-grain weight and that resulted in reduction of grain yield/ha. Similar results were reported by Pal et al (2017) and Huang et al (2020) who concluded that adverse environmental conditions (high temperature) affected panicle fertility levels and decreased grain weight, and consequently grain yield was reduced. With regard to the effect of hill spacing, the data (Fig 4-b) revealed a gradual increase in grain yield up to 20 x 15 cm then gradually decreased at the widest hill spacing of 30 x 15 cm.…”

Two field experiments were conducted in the summer seasons of 2018 and 2019 at the Agricultural Research Station, Alexandria University, Egypt. The aim of the study was to investigate the effects of sowing date (May10, May 20, June 10 and June 20), hill spacing ( 10 x 15, 15 x 15, 25 x 15 and 30 x 15 cm) and zinc sulphate fertilizer level ( 0, 12, 36 and 48 kg ZnSO4/ha) on grain yield and yield components of rice cultivar Sakha 106. The design applied in the two seasons was partially replicated central composite design in which factorial and star points were replicated three times. The results indicated that delaying sowing resulted in progressive decrease in 100-grain weight and grain yield (beyond May 10), number of effective tillers/m 2 and number of grains/panicle (beyond May 30). Hill spacing of 20 x 15cm was found to be optimal for number of grains/panicle, 100-grain weight and grain yield/ha, whereas number of tillers/ m 2 was highest at 30 x 15cm hill spacing. Zinc sulphate fertilization level of 48 kg/ha increased all yield and yield components. It could be concluded to sow cultivar Sakha 106 in the region early on May 10 at hill spacing of 20 x 15cm and application of 48 kg ZnSO4/ha to obtain high grain yield potential as a result of optimal production of yield components.

“…This method eliminates the need for seedling breeding and transplanting, saves water resources, improves labor efficiency, and optimizes both land use efficiency and adaptation to mechanization. Both seeding rate and nitrogen rate are important cultivation measures that affect rice yield formation and population composition 6 , 7 . It has been shown that increasing nitrogen rate and density can increase the effective panicle number and plant number in rice populations, while the increase of panicle number and spikelets per panicle are mutually constraining 8 .…”

This study used the rice cultivar Suijing 18 to investigate the effects of morphological characteristics, photosynthetic changes, yield, as well as nitrogen absorption and utilization. The interaction between seeding rate and nitrogen rate was also assessed to identify the most suitable values of the dominant population for both factors under dry cultivation. Furthermore, the photosynthetic physiological characteristics of the upper three leaves in the dominant population were also explored. The results showed that a combination of 195 kg/ha seeding rate and 140 kg/ha nitrogen rate achieved high yield, high nitrogen utilization, and moderate morphological characteristics. This was achieved by a coordination of the combined advantages of population panicle number and spikelets per panicle. The photosynthetic potential of the population was improved by coordinating the reasonable distribution of light energy in the upper three leaves, which led to the emergence of a dominant rice population under dry cultivation.
