Effect of Different Nitrogen Levels and Varieties on Protein and Nitrogen Content in Grain and Nitrogen Uptake by Barley (Hordeum vulgare L.) in Sodic Soil

Abstract

Rabi season of 2016-17 to study the performance of barley varieties under various nitrogen levels in sodic soil. The trial was laid out in Split Plot Design. Nitrogen levels (60, 75 and 90 kg N ha -1 ) were kept in main-plots and varieties (RD-2907, RD-2552, NDB-1173 and RD-2794 in sub-plots with three replications on sodic soils having low organic carbon (0.38 g kg -1 ), available nitrogen (185.0 kg ha -1 ), phosphorus (15.25 kg ha -1 ) and potassium (265 kg ha -1 ). Data manifested to nitrogen content and uptake of barley grain and straw as influenced by nitrogen levels and varieties. Maximum nitrogen content (1.68) in grain, (0.54%) in straw determined with application of 90 kg N ha -1 which was at par with the dose of 75 kg N ha -1 and lowest with 60 kg N ha -1 . The Maximum nitrogen uptake in grain (47.13 kg ha -1 ) and straw (24.80 kg ha -1 ) was recorded under the supply of 90 kg N ha -1 which was significantly higher than 75 and 60 kg N ha -1 . There was no significant difference in term of nitrogen content in grain due to different varieties of barley crop. Maximum nitrogen content (0.55) in straw was recorded in variety RD-2907 which was at par with RD-2552 (0.54%) and significantly maximum over rest of the varieties. Among the varieties of barley, maximum nitrogen uptake by grain and straw (48.31 and 25.25 kg ha -1 , respectively) was recorded in variety (RD-2907) which was at par with (24.52) RD-2552 and significantly superior to RD-2794 and NDB-1173. Nitrogen and protein content in grain increased with increasing levels of nitrogen. Maximum nitrogen content (1.68%) and protein content (10.54%) in grain was observed with 90 kg N ha -1 . The varieties had no significant effect on nitrogen and protein content in grain.

Response of Nitrogen Levels and Cutting Management on Growth and Yield of Dual Purpose Barley

“…Due to higher green forage yield (Table 1), seed yield (Table 1) and straw yield (Table 1) after the treatment of 120 kg nitrogen per hectare, the dual purpose barley seed equivalent yield increased. Findings from Yadav et al (2003) and Singh et al (2009) also noted similar results.…”

“…Along with intensive selection work, scientific research on the introduction of new species into culture, including local flora, especially in regions rich in natural species diversity, remains relevant at the present time [33,34].…”

“…The lowered protein content of jute may have resulted from reduced nitrogen uptake from the soil. Earlier studies showed that the protein content of plants increases with increasing soil nitrogen [33,34]. The reduced nitrogen uptake may be due to the competition caused by 6 Mexican sunflower plants per pot.…”

“…in the Fertile Crescent [2]. It is an important crop, especially in areas where wheat cultivation is not feasible, thanks to some of its characteristics such as greater environmental adaptability, lower water requirements, tolerance to stress conditions, and ability to grow in either saline [3] and alkaline soils [4]. Barley has several applications, e.g., as seed in the malting industry and as livestock feed as a whole plant for hay, silage, green feed, or even as straw [5].…”
