“…Higher nitrogen use efficiency and more recovery of applied nitrogen in T 3 may be supposed possibly due to reduced N losses through volatilization and denitrification from added dhaincha which releases nitrogen slowly. Similar opinion was also put forward in rice (Naresh et al, 2016).…”

A field trial was conducted during kharif 2014 to investigate the nitrogen use efficiency and yield of basmati rice under different schedule of nitrogen application through integration. To this effect ten treatments consisting various nitrogen scheduling were tested in a randomized block design with three replications. Remarkable effect was noted where growth attributes (plant height, number of tillers), yield attributing traits (panicle length and number of grains per panicle), yields viz., grain and straw yield and nitrogen use efficiency (agronomic efficiency, apparent N recovery and physiological efficiency) were improved with the application of 37.5/50% basal N through dhaincha and rest 47.0/37.5% at maximum tillering and 15.5/12.5% at panicle initiation, through urea. Even though, significantly highest grain (42.98 q ha -1 ) and biological yield (140.87q ha -1 ) was registered under the application of 50% N as basal through dhaincha + 37.5, and 12.5% N as through urea, at maximum tillering and panicle initiation respectively as compared to all other treatments. While, higher straw yield (105.34 q ha -1 ) was produced under combined application of 37.5% N as basal through dhaincha + 47.0, and 15.5% N as through urea, at maximum tillering and panicle initiation respectively. Thus, 50% N as basal through dhaincha + 37.5, and 12.5% N as through urea, at maximum tillering and panicle initiation, respectively, is best option for achieving maximum yield and nitrogen use efficiency.

“…On the whole, the average values N t were increased by 49% and 59% in variants RR and WR, or compared with the control (Table 1). The crop residues are considered to be the essential source of the organic substance (Naresh et al 2017), therefore their application into soil is associated with the increased content C and also N in soils (Christensen et al 1994). The changes after application of the crop residues into soil correspond with the chemical composition (Zaujec and Šimanský 2006) of the crop residues themselves.…”

Agroecosystem crop residues are considered to be a primary resource of organic substances, and are subject to the different transformation processes in the soil environment. The decomposition processes of organic substance can be also regulated by the application of the different biopreparations. The decomposition of organic substances in soil also causes changes in nitrogen content and its forms. It is essential for farmers to know about these processes in order flexibly to regulate and affect the transformation processes of the applied crop residues via the biopreparations directly in the production conditions. The changes of content and forms of nitrogen and its calculated parameters in Haplic Luvisol influenced by the applied crop residues (wheat – WR, rape – RR) and biopreparations (Betaliq, Trichomil) were monitored in the small-pot experiment carried out at the Department of Soil Science (FAFR, SUA-Nitra). The laboratory experiments were established for the incubation period 4, 7, 14, 28, 60, 90 and 180 days. The applied crop residues had statistically significant impact on the contents of total nitrogen (Nt) and potentially mineralizable nitrogen (Npot) and inorganic forms N, similarly also the values of labile nitrogen (LN) and nitrogen pool index (NPI). The biopreparations affected statistically significantly the average values Npot, LN, nitrogen lability index (NLI) and nitrogen management index (NMI). During the incubation period, the contents Npot and values LN and other calculated indexes of nitrogen fluctuated significantly.
