“…6°C day and 1,1748°C day-hr) and brown top millet (2,295.4°C day and 11,999.2°C dayhr) were found to be statistically similar and accumulated significantly higher GDD and HTU, respectively, to attain the physiological maturity compared to other tested nutricereals. Various researchers also reported similar results for different nutri-cereals (Maurya et al, 2015;Bhuva and Detroja, 2018).…”

An experiment was conducted during summer seasons of 2017 and 2018 on clay-loam soil of the ICAR-Research Complex for Eastern Region, Patna, Bihar, to study the performance of different nutri-cereals and their heat-unit requirements to complete their phenological cycles. Significantly higher grain yield, i.e. 1.92, 1.76 and 1.53 t/ha, was achieved in barnyard millet (Echinochloa esculenta (A. Braun) H. Scholz) followed by sorghum [Sorghum bicolor (L.) Moench] and pearl millet [Pennisetum glaucum (L.) R. Br.], respectively. Whereas the higher straw and biological yields were observed in sorghum (8.91 and 10.8 t/ha), pearl millet (7.14 and 8.67 t/ha) and little millet (Panicum sumatrense Roth ex Roem. & Schult.) (5.50 and 6.67 t/ha). Barnyard millet also showed the maximum crop productivity (24 kg/ha/day). Remarkably higher biomass productivity was noted in sorghum (114.7 kg/ha/day), followed by pearl millet and little millet (96.3 and 85.5 kg/ha/day). Pearl millet (702.9°C-day) accumulated the minimum growing degree-days (GDD) to attain 50% flowering. Further, pearl millet (4,111. 4°C day-hr) being at par with proso-millet (Panicum miliaceum L.) (4,280.3°C day-hr) and little millet (4,295.7°C day hr) attained significantly lower heliothermal units (HTU) to reach 50% flowering. Barnyard millet (1.25 kg/ha °C-day), followed by sorghum and pearl millet (1.01 and 0.91 kg/ha °C-day) acquired considerably higher HUE for grain production. Sorghum (6.11 kg/ha °C-day) followed by pearl millet (5.17 kg/ha °C-day) and little millet (4.48 kg/ha °Cday) captured significantly maximum HUE for biomass production. Our results indicated that, cultivation of nutri-cereals such as barnyard millet, sorghum, pearl millet and little millet is a viable option to utilize the fallow period (summer season) for achieving the nutritional security and realizing the livelihood improvement in this region.

“…Anas et al [40] reported that increments in nitrogen level prolong the duration of the crop, as nitrogen leads to prolific vegetative growth and could be the reason for the delay in achieving each phenophase. Differences in the accretion of heat units among cultivars might be due to variation in the duration of these varieties to attainment of maximum tillering [41]. In this study, we observed that the crop accumulated a greater number of GDDs and HTUs at higher levels of nitrogen to reach different phenophases.…”

Transplanting rice appears to pose many problems, including depletion of freshwater reservoirs and competition for labor. Conversely, direct seeding allows us to overcome shortcomings associated with conventional transplanting. Nitrogen is a crucial nutrient needed for plant growth and yield. Therefore, this study was executed to analyze the influence of nitrogen on the performance of rice genotypes grown by direct seeding in wet soil. The experiment comprised various rice cultivars, i.e., Shalimar Rice-1, Shalimar Rice-3, Shalimar Rice-4, and Jhelum, and nitrogen (N) levels, i.e., 0, 90, 120, and 150 kg/ha. Shalimar Rice-4 produced a maximum grain yield (6.39 t/ha), followed by Shalimar Rice-3 and Jhelum). The application of 150 kg N/ha showed maximum values for growth parameters, yield attributing traits, and grain yield (6.68 t/ha); however, it remained at par with 120 kg N/ha. Crop water productivity was highest in Shalimar Rice-4 (0.49 kg/m3), and the same showed a consistent increase with increasing N levels from 0–150 kg/ha, with a comparable value of 0.49 to 0.51 recorded at 120 and 150 kg N/ha. Moreover, the Shalimar Rice-1 variety required the maximum in growing degree days (GDD) and helio-thermal units (HTU) to attain different phenological stages till physiological maturity (131 days). However, the cultivar Shalimar rice-4 (SR-4) performed better by registering significantly higher heat use efficiency (HUE) (4.44 kg/ha °C/day). Additionally, the highest net return and the benefit-cost ratio were registered by Shalimar Rice-4. B:C ratio of 1.75 was realized from application of 150 kg N/ha, which remained very close to that achieved with 120 kg N/ha. In conclusion, the rice cultivar Shalimar Rice-4 with the application of 120 kg N/ha could boost rice production under DSR in water-scarce regions of temperate northern India.
