“…They reported 1000 grain weight of 210.43 g by the application of 250 kg N ha -1 . Similar result was obtained by Sharar et al (2003), who reported the 1000 grain weight of 226.5 gm by the application of 210 kg N ha -1 . Karki (2002), Akbar et al (2002) and Gokmen et al (2001) reported the increase in 1000 grain weight with the increasing dose of Nitrogen due to a higher amount of photosynthates to the grains.…”

Nitrogen (N) fertilizer is considered as one of the most important factors affecting growth and grain yield of hybrid maize. This study was conducted to determine the effects of different rates of nitrogen and varieties on growth and yield of hybrid maize in Lamahi Municipality, Dang, Nepal from June to October, 2019. Three levels of hybrid maize varieties (10V10, Rajkumar F1 and NMH-731) and four levels of nitrogen (160, 180, 200 and 220 kg N ha-1) were evaluated using two factorial randomized complete block design with three replications. The results showed that grain yield and yield attributing traits of hybrid maize varieties increased with the increasing level of nitrogen from 160 to 220 kg ha-1. The application of nitrogen @ 220 kg N ha-1 produced the highest grain yield (10.07 t ha-1), cob length (16.33 cm), no of rows per cob (14.97), no of grains per row (33.37), cob diameter (4.54), thousand grain weight (276.77 g), stover yield (12.91 t ha-1), biological yield (23.00 t ha-1), harvest index (43.80), gross return (NRs. 208940 ha-1), net return (NRs.104488 ha-1) and B:C ratio (2.001). The hybrid maize variety 10V10 produced the highest grain yield (9.35 t ha-1), net returns (NRs. 91740.66 ha-1) and B:C ratio (1.91) accompanied by the highest cob length (16.25 cm), and as number of grains per row (32.35) as compared to other varieties. This study suggested that maize production can be maximized by cultivating hybrid maize variety 10V10 with the use of 220 kg N ha-1 in inner Terai region of Nepal.

“…The value of this feature at this nitrogen dose was higher by 30.40 g on average compared to the control object, while the smallest mass of one thousand seeds was obtained after the application of 80 kg N•ha −1 . A similar tendency was confirmed in the research by Khaliq et al [24] and Sharar et al [25]. Means followed by the same letters do not differ significantly at p = 0.05.…”

The field experiment was carried out in 2015–2017 on a family farm in Toczyski Czortki, in the Mazovia voivodeship in Poland. The experiment was set up in a split–split–plot system in three replications. The area of one plot was 30 m−2. The studied factors were: I—two maize varieties: PR38N86 (medium late hybrid cultivar 280 FAO), P8400 (medium early hybrid cultivar 240 FAO); II—four doses of nitrogen fertilization: 1. control object—without the use of nitrogen (0 kg N·ha−1), 2. nitrogen dose—80 kg N·ha−1 (applied once before sowing), 3. nitrogen dose—120 kg N·ha−1 (applied once before sowing), 4. nitrogen dose—160 kg N·ha−1 (applied once before sowing); III—four types of biostimulants used: 1. control object—without using a biostimulant, 2. Asahi®SL biostimulant: I term—four-leaf phase (BBCH 14) at a dose of 0.60 dm3∙ha−1, II term—eight-leaf phase (BBCH 18) at a dose of 0.60 dm3∙ha−1, 3. Improver® biostimulant: I term—four-leaf phase (BBCH 14) at a dose of 1.00 dm3∙ha−1, II term—eight-leaf phase (BBCH 18) at a dose of 0.60 dm3∙ha−1, 4. Zeal® biostimulant: I term—six-leaf phase (BBCH 16) at a dose of 2.00 dm3∙ha−1. The aim of the study was to determine the effect of nitrogen fertilization and the use of biostimulants on the size and quality of yield of two varieties of maize grown for grain. Based on the conducted research, it was found that nitrogen doses influenced the amount of maize grain obtained. The highest yields were obtained using 120 kg N∙ha−1. Nitrogen doses significantly affected the studied maize yield components. The dose of 120 kg N∙ha−1 increased the number of grains in the cob, while the dose—160 kg N∙ha−1 exerted the best effect on obtaining the highest values of a thousand seeds. The biostimulants used in the experiment significantly affected the mass of one thousand seeds and the number of grains in the cob. In addition, Asahi®SL, Improver® and Zeal® biostimulants increased maize yield in each growing season studied.

“…These finding is in line with the results of Zada et al [17] and Iqbal et al [16] who reported that plant height increases with the increase in nitrogen doses. Increase in plant height of oat with nitrogen application has also been reported by Sharar et al [18] and Ayub et al [15].…”

The present study was conducted to assess seed rate (SR) and nitrogen rate (NR) effects on biomass yield and nutritional quality of oat (Avena sativa L.) at Sirinka, North Eastern Amhara, Ethiopia on July 2018. Levels of SR were 60, 80 and 100 kg/h and that of NL were 50, 100 and 150 kg/ha in the form of Urea (46% N). The experiment was conducted in a 3x3 factorial arrangement of treatments in a Randomized Complete Block Design (RCBD) with 3 replications giving a total of 27 plots, each measuring 2×1.4 m2. Growth and yield parameters were analyzed. Results showed that the interaction between seed rate and nitrogen rate had a significant (p<0.05) effect on almost all parameters measured except tiller number per plant (TNP). Green forage yield and dry matter yield increased with increasing level of seed rate and level of nitrogen. Generally, combination of 100 kg/ ha seed rate and 150 kg/ha nitrogen recorded higher forage yield. Thus, seed rate of 100 kg/ha and nitrogen fertilizer rate of 150 kg/ha Urea can be recommended for use by farmers in Sirinka area and other areas having similar agro-ecologies and soil type.
