The basic aim of this study was to compare the denitrification efficacy of 2,5-dichloroaniline, Ammonium Thiosulphate and their combination (1:1) with previous studies. Ammonium Thiosulphate was not used as a nitrification inhibitor in previous research. Our findings depict that there was significant variation among the chemicals, soil and levels in denitrification for early seedling growth of wheat.

Nitrogen is the most important nutrient for plants, most used in agricultural production. Among nitrogen fertilizers, urea is the most used to provide nitrogen for plants. Due to the effects of climate change, leaching, erosion and improper use have reduced the effectiveness of fertilizers when applied, causing environmental pollution.

The current study includes the histopathological alterations induced by chronic (20 days) exposure of the fish Anabas testudineus to a sublethal concentrations (27.5 mg/L) of inorganic fertilizer, Urea [CO(NH2)2]. Some vital organs were taken for the study that is kidney, liver, intestine, testis and ovary. The present study showed major histopathological alteration like vacuolar degenerative changes, necrosis etc. found in liver, intestine, testis, ovary and kidney organs dysfunction in response to urea toxicity effect in the fish A. testudineus.

This study was conducted with synthetic wastewater from urea and ammonia (representing nitrogen fertilizer production wastewater) and additional carbon source of methane (CH4). Methane and air were supplied to microbial liquid phase using a bubble air stone aerator located at the bottom of a bioreactor with methane gas flowrate ranges from 1 to 2 L/h, air flowrate ranges from 3 to 6 L/h.

Coated products mostly consist of quick-release N sources surrounded by a barrier that prevents the N from releasing rapidly into the environment. Keeping the above aspects in the mind, the present proposal is put forth with the effect of slow releasing nitrogen fertilizers on growth and yield of sugarcane.

Effect of foliar spray of various nutrients on yield attributes, yield and economics of rainfed rice
A recent trend in the fertilizer industry to shift from ammonium sulphate to urea and from superphosphate to non-sulphur phosphatic fertilizer may induce more widespread sulphur deficiency in lowland rice. Keeping all above facts in view the present study was undertaken to find out the nutrient economy through foliar application of fertilizer and to assess the economic feasibility of various treatments.

The field study consisted of eight treatments, in which drip fertigation was given in T1 to T3 with 75%, 100% and 125%of recommended dose (RDF, 80:40:40 kg NPK/ ha) as straight fertilizers N and K (urea and MOP) and SSP was applied as basal dose. In T4 to T6 fertigation provided with 75%, 100% and 125% RDF of water soluble fertilizer (19:19:19). Drip irrigation with 100% RDF (all as soil application) was given in T7 and T8 with drip irrigation and STCR based fertilizer application.

A field experiment was carried out at ‘A-B’ Block farm of BCKV, West Bengal, during subsequent winter seasons of 2017-18 and 2018-19 with grass pea variety Ratan (Bio L-212). Ten treatment combinations were laid out in a factorial RBD consisting seed priming with Ammonium molybdate @ 0.5 g kg-1 seed and foliar feeding at pre-flowering or a second spray at 15 days interval using 2% Urea or 0.5% NPK (19:19:19) to analyse their effect on quality and nutrient uptake of relay grass pea.

Nitrogen plays a pivotal role in fruit tree performance. It is a major constituent of plant cell and plays an important part in the plant metabolism. Considering the marked effect of nitrogen, its application in fruit trees has been investigated by several researches in India as well as in world. Previously, the studies remained confined to fruit yield and tree growth.

To study the impact of artificial creation of soil fertility gradient strategy on soil fertility, nutrient uptake and green fodder yield of sorghum (var. CO 30) by following inductive methodology (fertility gradient concept), a field experiment was conducted during 2014-15 at farmer’s holding of Coimbatore district. The experimental field was divided into three equal strips and three graded levels of fertiliser N, P2O5 and K2O were applied in the form of urea, single super phosphate and muriate of potash, respectively to strip I (N0P0K0), II (N1P1K1) and III (N2P2K2).

Rice (Oryza sativa L.) is one of the most important staple food crops worldwide. Nitrogen (N) is the most important nutrient in irrigated rice cultivation. Current high yields of irrigated rice are often associated with applications of higher doses of fertilizer N, as nearly 30-40 percent of applied nitrogen is actually utilized by the crop; even with the best agronomic practices. It has always been a problem to raise the utilization rate of the rice plant and to increase efficiency of absorbed nitrogen for grain production.
