Effect of Nitrogen Management Strategies on Yield, Quality and Nitrogen Uptake by Wheat (Triticum aestivum L.)

There is little knowledge among farmers on the rate of nitrogen-fertilizer application. Therefore, there is a need to determine optimal rate of nitrogen-fertilizer application on growth and yield of wheat. Accordingly, an field experiment was conducted during the winter (Rabi) season at Crop Research Centre the Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh, to study the impact of different nitrogen level and splitting modules on quality, yield and nitrogen uptake by wheat (Triticum aestivum L.) crop. The main object of investigation was to find out the optimum dose and splitting of nitrogen for wheat in irrigated system under integrated nitrogen management approach. The experiment consisting of four nitrogen levels viz. control i.e. 0 kg N ha-1 , 90 kg N ha-1, i.e 120 kg N ha-1 and 150 kg N ha-1 as main plots and four splitting modules M1- 50% N as basal through VC, + 25% at CRI + 25% booting stage through urea, M2-50 % N as basal through FYM + 25% at tillering + 25% at booting stage through urea, M3 -50% N as basal through VC+FYM (1:1), + 25% at tillering + 20% at booting stage and 5 % N as foliar spray at pre flowering stage through urea, M4 -50% N as basal through VC+FYM (1:1), rest based on SPAD reading through urea as sub-plots. The experimental results revealed that the plot which fertilized with 150 kg N ha-1 gave higher yield-attributing characters and yield (grain, straw and biological yield). The application of 150 kg N ha-1 resulted in 0.44, 15.25 and 80.8 per cent during 2016-17 and 0.41, 13.05 and 79.2 per cent during 2017-18 produced the higher grain yield over 120, 90 and 0 kg N ha-1. The content and uptake of nitrogen by grain, straw and total uptake as well as protein content and protein yield were obtained with 150 Kg N ha-1 but differences between 120 and 150 kg N ha-1 were non-significant, during both the year 2016-17 and 2017-18. Among different splitting modules M3 resulted significantly higher entire yield attributes, yield (grain and straw yield), nitrogen content and uptake by grain, straw and total uptake as well as content and yield of protein. The M3 module produced higher grain yield by 7.9, 14.7 and 24.8 per cent during 2016-17 and 8.1, 14.89 and 25.2 per cent during 2017-18 over M4, M1 and M2 splitting modules, respectively.

A field experiment was conducted at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand with a view to study the Influence of integrated nitrogen management on growth and yield of beet root (Beta vulgaris L.) var. Crimson Globe during rabi, year 2020-21. The experiment was arranged in Randomized Block Design (RBD) with three replications which includes 10 treatments. The results revealed that significantly maximum plant height of 16.71, 35.20 and 35.25 cm at 25, 50 DAS and at harvest, respectively observed in T3 (60 kg N/ha + 5 t/ha Vermicompost + 5 t/ha Castor cake). Similarly, the same treatment T3 was registered maximum number of leaves per plant at 25 (6.50), 50 (10.68) DAS and at harvest 14.30. The maximum fresh weight of leaves (224.45 g), dry weight of leaves (13.35 g), as well as leaf area (260.42 cm2) was also recorded with an application of 60 kg N/ha + 5 t/ha Vermicompost + 5 t/ha Castor cake. The yield attributing parameters viz. root length (16.23 cm), root diameter (7.85 cm), fresh weight of root (198.05 g), dry weight of root (18.75 g), root to shoot ratio (1.42), yield (21.91 kg/plot and 28.08 t/ha) and harvest index (55.68 %) was recorded in treatment T4 [60 kg N/ha + 12.5 t/ha FYM + 5 t/ha Vermicompost + Seed treatment of Anubhav Bio NPK consortium (5 ml/kg seed)].

Effect of Different Organic and Inorganic Fertility Sources on Protein Content in Pearl Millet Crop Grown in Sandy Soils

A field experiment carried out at the S.K.N. College of Agriculture, Jobner, Agronomy farm. The six treatments include four levels of liquid organic manures (control, panchgavya, vermiwash, and cow urine), which are given to the main and sub plots, respectively, and are replicated three times in the Split Plot Design. The integrated nitrogen management treatments include control, 100% RDN, 75% RDN + 25% N through FYM, 50% RDN + 50% N through FYM, 25% RDN + 75% N through FYM, and 100% N through FYM. As a test crop, the pearl millet variety "RHB 223" was used. The findings showed that integrated nitrogen management improved the performance of the pearl millet crop before having a residual effect on the mustard variety Giriraj (DRMR IJ-31). In addition to improved soil health in terms of physical and chemical properties, coordinated nitrogen management significantly raised soil organic carbon and improved crop routine. The application of 25% RDN + 75% N through FYM to pearl millet and 50% RDN + 50% N through FYM to mustard crop, among other treatments, had a residual effect that improved crop performance and quality content while also enhancing the physico-chemical properties of the soil. These methods demonstrate a viable approach to enhancing soil nutrient availability on a sustainable basis.

Effect of Integrated Nitrogen Management on Growth and Yield of Okra at Sundarbazar, Lamjung, Nepal

Integrated Nutrient Management (INM) is a crucial approach to improving the sustainable yield of crops in an environmentally friendly manner. In this study, a field experiment was conducted at Lamjung Campus, Sundarbazar, Lamjung, from March 2022 to June 2022 to evaluate the effect of integrated nitrogen management on the growth and yield parameters of okra and to find out the suitable nitrogen management system in okra. A randomized full-block design was utilized in the investigation, with seven treatments and three replications. The treatments consisted of a control (T1) and six other combinations of nitrogen sources, with each treatment receiving 50% of its nitrogen from chemical fertilizers and 50% from organic sources. The amount of organic manure was calculated based on the nitrogen content of the manures. Farmyard manure (FYM), poultry manure, vermicompost, mustard cake, and goat manure were tested as organic sources. The effect of treatment combinations was evaluated in terms of plant height, stem diameter, leaf numbers, days to first flower opening, days to first fruit maturity, number of pods per plant, length, and diameter of pods, and yield ha-1. The findings revealed that integrated nitrogen management strategies had a substantial impact on okra growth and output. Among all the treatments, 50% recommended N through chemical fertilizer + 50% N through poultry manure (T4), which gave the highest number of pods per plant (19.87), yield per ha (13.59 t/ha), and shortest days taken to first flowering (46.54 days) and plant height (54.80 cm), followed by T2, while the control treatment (T1) yielded the lowest. These findings suggest that the application of 50% recommended N through chemical fertilizer + 50% N through poultry manure is an effective strategy for obtaining a high yield of okra in the study area.

Dynamic emissions of N<sub>2</sub>O from solid waste landfills: A review

Nitrous oxide (N<sub>2</sub>O) is an important greenhouse gas (GHG) and an ozone-depleting substance that can be emitted from landfills. Understanding the dynamics of N<sub>2</sub>O and its contribution to total emissions is critical to effective mitigation measures. This study outlines the dynamics of N<sub>2</sub>O in solid waste landfills and N<sub>2</sub>O emissions from them. N<sub>2</sub>O generation in anaerobic landfills is primarily due to denitrification and, to a lesser extent, nitrification, which occurs in the oxygenated cover soil layer and the working face. However, nitrification and denitrification are very limited within landfills. The landfill leachate contains high concentrations of ammonia (NH<sub>3</sub>). Thus, a significant amount of N<sub>2</sub>O is generated from aerobic processes during leachate treatment. Bioreactor landfills emit more N<sub>2</sub>O than traditional anaerobic landfills. The majority of N<sub>2</sub>O emitted from bioreactor landfills is generated through different pathways, such as hydroxylamine (NH<sub>2</sub>OH) oxidation, nitrifier denitrification, and heterotrophic denitrification. These processes are affected by several factors, including the carbon-to-nitrogen (C/N) ratio, NH<sub>3</sub> oxidation rate NH<sub>3</sub> oxidation rate, redox conditions, and temperature. Addressing N<sub>2</sub>O emissions from landfills will be necessary to achieve an integrated nitrogen management strategy that helps minimize N<sub>2</sub>O emissions.

Integrated Nitrogen Management on Weed Growth and Yield Performance of Transplant Aman Rice

Rice requires nitrogen in larger quantities than any other nutrient, and it is the most critical limiting factor that influences grain yield. But inappropriate sources and management of nitrogen is considered to be the most critical one among the various reasons of low rice productivity. In order to address the problem, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during June to October 2020 to determine the effect of integrated nitrogen management (INM) on weed growth and yield of transplant aman rice. The experiment comprised five aman rice varieties, viz. Binadhan-7 (V1), BRRI dhan56 (V2), BRRI dhan66 (V3), BRRI dhan71 (V4) and BRRI dhan75 (V5) and four nitrogen management approaches: control (no nitrogen) (N0), 100% of recommended dose (RD) of nitrogenous fertilizer as prilled urea (150 kg ha-1) (N1), 2.5 t ha-1 poultry manure + 75% of RD of nitrogenous fertilizer as prilled urea (112.5 kg ha-1) (N2) and application of USG (1.8 g per 4 hills) (N3). Results reveal that maximum weed density and dry weight were found in BRRI dhan56 whereas minimum ones were observed in BRRI dhan66. In case of INM, application of 100% of RD of nitrogenous fertilizer as prilled urea showed maximum weed density and dry weight but minimum ones were found with application of USG. In combine, weed density and dry weight were found highest in BRRI dhan56 with 100% of RD of urea and the lowest weed density was found in BRRI dhan66 with no nitrogen treatment at 20 DAT and in BRRI dhan66 with application of USG at 35 DAT and lowest weed dry weight was obtained from Binadhan-7 with application of USG (1.8 g per 4 hills) at 20 and 35 DAT. Variety Binadhan-7 showed superior performance in terms of yield and yield attributes. Application of USG showed the highest number of grains panicle-1 and grain yield. Interaction of Binadhan-7 with application of USG produced highest number of grains panicle-1 (116.60), highest grain yield (5.21 t ha-1), biological yield (10.94 t ha-1), harvest index (47.65%) and highest BCR (1.57). So, results indicated that Binadhan-7 with application of USG (1.8 g per 4 hills) might be recommended for obtaining highest grain yield with higher nitrogen use efficiency, highest BCR as well as to control weed more effectively in aman season.

Aim: To study the effect of sowing time and integrated nitrogen management on yield and post-harvest soil nutrient status of black glutinous maize (Zea mays L.).
 Study Design: Factorial randomized block design (FRBD).
 Place and Duration of Study: Experimental field of College of Agriculture, Central Agricultural University, Imphal, Manipur, pre-kharif season of 2018.
 Methodology: The treatment consisted of four different integrated nitrogen management practices and three sowing dates.
 Results: The result revealed that maximum cob length (16.97cm), cob girth (15.71cm), test weight (257g), grain yield (32.9 q/ha) and shelling % (80.31%) was observed in the treatment N3 (RDN- 75% through urea + 25% through FYM) among different integrated nitrogen management practices. The highest yield among different sowing dates was recorded on plants sown on 9th April (28.23 q/ha). The different integrated nitrogen management showed significant difference in residual nutrients and organic carbon in soil. Maximum available nitrogen (275.97 kg/ha), phosphorus (19.21 kg/ha), potassium (210.05 kg/ha) and organic carbon (1.10%) were observed in treatment N4 (RDN- 100% through FYM). Lowest values of nutrients under study were observed in treatment N1 where the crop received only chemical fertilizer.

Rice (Oryza sativa L.)–Baby Corn (Zea mays L.) Cropping System Response to Different Summer Green Manuring and Nutrient Management

The nutrient and biomass supply capacity of green manure (GM) and its complimentary and synergistic relationship with chemical nutrients is needed for a sustainable rice–baby corn cropping system in the eastern part of North India. A two-year field study was performed to assess the effect of GM and nitrogen management (NM) on yield attributes (YA), the yield of rice, and their residual (R) effect with the half-recommended dose of fertilizers on the succeeding baby corn crop. The combination of GM and N levels had significant effects on rice yield, which also influenced the succeeding baby corn crop. A higher number of tillers/m2, panicle length (cm), number of grains/panicles, panicle weight (g), grain yield (Mg/ha), straw yield (Mg/ha), and biological yield (Mg/ha) were found with Sesbania aculeata incorporated at 45 DAS (SA), which was statistically on par with water hyacinth 5 t/ha dry weight basis (WH) during both years of the field study. Among the rates of nitrogen fertilizers, 100% RDN (50% N through FYM + 50% N through inorganic) (RDN100) was the best treatment with a corresponding increase in all YA and yields of rice. It has been proven that integrated nitrogen management (INM), or the use of organic material along with fertilizer, is an effective way of managing nitrogen. In the present investigation, green manuring and integrated nitrogen management on rice sustainably increased the yield attributes and yield of the succeeding baby corn. These results illustrated the complementary effects of summer green manuring in conjunction with INM in maximizing the yield attributes and yields of rice, its residual effect on succeeding baby corn, and the economics of the system.

Effect of Integrated Nitrogen Management Treatments on Growth Yield and Economics of Soybean [Glycine max (L.) Merrill

Soybean, being an important pulse as well as oil seed needs special mention to overcome crisis in edible oil production in the country. It is also called as “Gold of soil”. An experiment was conducted at College of Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) during kharif (Soybean) and rabi (Amaranthus) season of the years 2019-20 and 2020-21. An agronomical investigation entitles effect of integrated nitrogen management in soybean and their residual effect on grain amaranthus under irrigated condition. The experiment soil was medium in organic carbon (0.40%), available phosphorus (36.20 kg/ha) and available potassium (209 kg/ha) with soil pH (8.15). There were ten integrated nutrient management treatments arranged in Randomized block design with four replications. Integrated used of the organic and inorganic sources of plant nutrients on growth and yield attributes is very crucial for the assurance of food securities. Different observation on the crop parameters were carried out during course of investigation. Integrated nitrogen managements did not exert any significant response on plant population recorded at 20 DAS and at harvest and plant height at 30 DAS. All growth and yield parameters viz., plant height at 60 DAS, plant height at harvest, number of branches/plant, root nodules/plant, dry weight of root nodules, seed yield and straw yield were recorded significantly higher with the application of 50% RDN through vermicompost + 50% RDN through inorganic fertilizer (T3) sustainable agricultural productivity might be due to achieved through wise used of integrated nutrient management. At present soybean is one of the most important economical crops and having good nutritional response on healthy diet and information of same cropping sequence was not available for farming community so planned study on the application of organic sources of nutrients viz., vermicompost, FYM, bio-fertilizers (Rhizobium + PSB) under middle Gujarat conditions.

EFFECTIVENESS OF COMPOST, POTASSIUM HUMATE, AND INORGANIC FERTILIZERS ON MAIZE GROWTH

Food security is the major issue in Pakistan due to exponential increase in its population. Pakistan’ economy is highly dependent upon its agriculture sector which especially relies on its major crops. There is a huge gap between the output and actual requirements of food produce. The extensive cropping system over the years and specific crop rotation on the same organic matter are speedily converting productive and fertile soils into barren soils which are causing not only quantitative but also qualitative loss of crop outcome. There is a dire need to promote the use of non-conventional approached along with conventional approaches for maximum production of crops especially maize. In University of Agriculture Faisalabad a field trial was carried out at experimental area to figure out the effect of integrated nitrogen management on growth and yield of maize. In the experiment RCBD design was used with four replications. The integrated effect of potassium humate, compost and inorganic fertilizers on growth and yield of maize was studied under field conditions. Where humic acid @ 5 L ha-1 and compost @ 100 kg ha-1 along with NPK at @ 175:150:100 kg ha-1 were applied. Plant height, ear leaf length, number of grains per cob, grain yield, Chlorophyll content in leaves, nitrogen contents in grain and leaves and various other growth parameters were recorded at maturity. Integrated use of compost and humic acid along with NPK significantly affected all growth and yield parameters.
