Abstract
A field experiment was conducted in sandy clay loam soil of Agriculture College, RVSKVV, Gwalior during rabi season 2021-22. The experiment was conducted in a two way factor anova comprising of five elevated/ambient temperature viz., ambient in OTC, ambient+1oC, ambient+1.5oC, ambient+2oC, Open field (control) and two mustard cultivars at varied crop geometry i.e., RVM2 (45x10cm & 25x20cm) and Giriraj (45x10cm & 25x20cm). The experiment was replicated three times. Results revealed that significantly higher plant height (cm), no. of leaves per plant, root length (cm), no. of branches, no. of siliqua per plant, no. of seed per siliqua, length of siliqua (cm), 1000 seed weight (g), total biomass (q/ha), seed yield (q/ha) and harvest index (%) was obtained at ambient +1oC which were significantly superior over rest of the ambient temperature and open field control conditions. Maximum number of plant height (cm), no. of branches, no. of siliqua per plant, no. of seed per siliqua, length of siliqua (cm), 1000 seed weight (g), total biomass (q/ha) and seed yield (q/ha) was recorded with Giriraj (45x10 cm) mustard cultivar except no. of leaves per plant, root length (cm) and harvest index (%), respectively.
