This research aimed to extract lignin from rice straw and reveal the pH value of diluted acid at which the most effective yield of lignin was precipitated. In this study, rice straw obtained from local fields in the An Giang province of Vietnam and sodium hydroxide 2 M was employed to extract lignin from rice straw.

The paper "Sustainable rice straw management in Vietnam: Current situation, challenges and potential" aims to provide a broad overview of rice straw management and use issues in Vietnam, one of the largest rice-producing countries in the world and what is currently being done about them. It outlines potential options to addressing these issues going forward. In addition, it also identifies policy gaps, R&D needs, and suggests priorities for future research and investment.

The obtained results showed that the irrigation treatments (3 events) gave the lowest values for water consumptive use, grain, straw, biological yield and 1000-grain weight. Nitrogen fertilizer in ammonia up to 90 kg N fed1 decreased all characters studied except grain yield which has no any significant differences between both N levels.

This investigation was carried out in the Experimental Farm at Ghazala Village (Faculty of Agriculture, Zagazig University, Egypt) during two successive seasons (2014/2015 and 2015/2016) to study the effect of rice straw burning (rice straw plowing down and rice straw burning), phosphorus (P) level (0 and 15.5 kg P2O5/fad [fad = faddan = 4200 m2 and ha = 2.38 fad]), and nitrogen (N) level (30, 60 and 90 kg N/fad) on wheat (Triticum aestivum L. cv. Gemmiza 11).

The results show that with a total amount of 179.08 tons of PM10 and 163.3 tons of PM2.5 dispersed into the environment, causing local air pollution in the southern area of the city, where there is a large cultivated area, the rice-yield is high and the amount of straw burned in the field accounts for the majority.

A screen house experiment was conducted during rabi season of 2018-19 to find out the effect of different levels of P and Zn on wheat yield, concentration of different nutrients in grain and straw in low and high P status soil. Five levels of P (0, 30, 60, 120 and 180 mg P kg-1 soil) and four levels of Zn (0, 2.5, 5 and 10 mg Zn kg-1 soil) were applied in completely randomized design with three replications.

A field experiment conducted during 2014-15 and 2015-16 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.); to evaluate the productivity and profitability of wheat as influenced by planting methods and nutrient resources eastern Uttar Pradesh. Data revealed that planting methods; system of wheat intensification (SWI) found significantly higher plant height, plant dry weight, leaf area index, grains/spike, 1000-grain weight, grain yield, straw yield and economics of wheat over to FIRBS and conventional method of planting.

The research experiment was carried out using the Botanicals with wheat straw to evaluate the growth and yield parameters of oyster mushroom (Pleurotus florida). The botanicals were evaluated in combination with wheat straw (wheat straw + Neem, wheat straw + Lantana, wheat straw + Turmeric, wheat straw + Guava, wheat straw + basil and wheat straw alone) to find out best botanical supplemented that support the growth of oyster mushroom.

A field experiment was conducted on a silty clay loam soil (acidic in reaction and medium in available NPK) during Rabi 2018-19 at Palampur to study the influence of nutrient management practices (Inorganic (RDF), Organic, Natural and Integrated) and varieties (‘Him Palam Alsi-2’, ‘Himani’ and ‘Priyam’) on yield, uptake, quality and soil properties in linseed. Results, revealed that among different nutrient management practices, Integrated Nutrient Management being at par with inorganic practice resulted in significantly higher seed, straw, uptake of NPK and oil yield.

This study, the rice straw was pretreated with sodium hydroxide as the step of rice straw pretreatment in bioethanol production, and then lignin was recovered by acidification method. The obtained lignin was characterized by Fourier-transform infrared (FT-IR) and X-ray powder diffraction (XRD) to confirm the chemical structure, inorganic matter. To produce sodium lignosulfonate (NaLS), the sulfomethylation was conducted between lignin, formalin, and sodium sulfite.

A field experiment was conducted during Kharif season of 2018 in Alfisols to study grain yield of hybrid rice varieties as influenced integrated nutrient management. Results revealed that V1 (IRH-103) found significantly highest N, P and K contain in grain and straw of than V2 (IRH-111) and in different nutrient management N5 (150% RDF through inorganic) was observed significantly higher N, P and K contain in grain and straw.

To develop fertilizer prescription equation for rice, a field experiment was conducted on an inceptisol of farmer‟s field at Arachikuppam village, Puducherry during 2015 by using integrated plant nutrient management system on the basis of STCR approach. The rice grain and straw yield was significantly increased with the soil test values and fertilizer doses of N, P and K. Based on the experiment, the nutrient requirement for producing 1 quintal of rice grain was 1.46 kg of N, 0.60 kg of P2O5 and 1.12 kg of K2O, respectively.

A field experiment was conducted on “Effect of crop establishment methods on yield of rice (Oryza sativa L.) during summer under lowland farming situation” at Instructional cum research farm, S.G. College of Agriculture and Research Station, Jagdalpur, Chhattisgarh, India during summer 2019 in Randomized Complete Block Design (RCBD) with six treatments and four replications. Transplanting of 20 days old seedlings of MTU1010 was carried out on 25th February 2019 maintaining crop geometry of 20 x 10 cm within each plot and rice was harvested on 31st May 2019.

The main plot treatments comprised three sowings, viz. 22 ºC, 20 ºC and 18 ºC and subplots consisted of eight treatments of bio-regulators, viz. control, water spray, SA @ 100 ppm, SA @ 200 ppm, TSA @ 100 ppm, TSA @ 200 ppm, TGA @ 100 ppm and TGA @ 200 ppm. Crop sown at 20 ºC resulted in significantly highest yield and nutrient content over 22 ºC and 18 ºC. Among bioregulators, an application of salicylic acid @ 200 ppm registered significantly highest yield and nutrient content in grain and straw of wheat, thus, hold a great promise in wheat production under heat stress.

An on –farm trial was conducted on various farmers field in different villages of Araria district during financial year 2016-17. This trail was conducted to overcome weed infestation during cultivation of chilli in farmers field. It leads to reduction in yield; quality of produce is inferior as compared to better quality produce, increased the cost of cultivation due to manual hand weeding by laborers and reduced the benefit cost ratio. The trial was conducted in randomized block design with three treatments and ten replications.

Rice residues are important natural resources, and recycling of these residues improves the soil physical, chemical and biological properties. Management of rice straw is a major challenge as it is considered to be a poor feed for the animals due to high silica content. A field experiment was conducted at Agricultural Research Station, Bhavanisagar during 2014-2015 and 2015-2016 to review the suitable rice residue management practices and nutrient dynamics by using combine harvester operated rice field after cultivating rice.
