A field experiment was carried out during two consecutive years (2016-17 and 2017-18) at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyala, Chitrakoot, Satna,(M.P.). Indiato evaluate the effect of moisture conservation practices on growth, yield attributes and yield of mustard under rainfed condition. Treatment consisted four moisture conservation practices i.e. no irrigation, life saving irrigation, straw mulch (Paddy straw @ 4t/ha) and kaolin 5 % spray. Result revealed that on pooled basis the tallest plant of 195 cm was recorded under life saving irrigation but number of branches (6.82) and dry weight per plant (39.8 cm) were significantly maximum in straw mulch treatment. The yield attributes such as siliqua per plant (298.5), seeds/siliqua (15.9), siliqua length (3.97 cm), seed weight per plant (17.06 g) and 1000- seed weight (5.57 g) were significantly superior under straw mulch followed by life saving irrigation. Significantly highest seed yield (2558 kg/ha), oil content (42.0 %) and protein content (20.5%) were obtained under straw mulch treatment while numerical enhancement was observed in life saving irrigation and kaolin 5% spray over no irrigation.

Sugarcane bagasse biochar enhances the growth parameters, haematological parameters, and enzyme activities of genetically improved farmed tilapia (GIFT) reared in inland saline water.

In the present scenario, waste management, especially agro-waste, is one of the major challenges. India is an agrarian country and the economy depends on agriculture and a huge amount of agro-wastes are generated. In this study, biochar was prepared from paddy straw and sugarcane bagasse and was used in the feed of genetically improved farm tilapia (GIFT) at 0.5% (w/w) basis to study its effect on growth and haematological parameters. An experiment was carried out in triplicate in 500-l capacity FRP tanks comprising two treatments and one control. Tanks were filled with inland saline soil to maintain 25-cm soil's bed and water with 12 ppt salinity. A total of 22 fish having an average length of 5.14 ± 0.07cm and weight of 4.8 ± 0.05g were stocked in each tank; the fish were fed at apparent satiation level, twice daily for 45days. It was observed that growth parameters like SGR% (specific growth rate), weight gain (WG%), and feed conversion ratio (FCR) were significantly improved (p < 0.05) than the control. Biochar-enriched feed also significantly improved the haematological parameters like red blood cell (RBC), white blood cell (WBC), haemoglobin (Hb) haematocrit % (HCT), mean cell haemoglobin concentration (MCH), and MCV (mean cell volume) in treatment groups than the control. Feeding biochar as feed additives was also found to decrease catalase (CAT) and enhanced amylase and lipase activities in treatments as compared to control (p < 0.05). It can be concluded that the application of biochar as a feed additive enhanced the growth and overall health of the fish, and it can enhance fish production. However, biochar from sugarcane bagasse was found to be more effective than the paddy straw biochar in the diet of tilapia (GIFT).

The addition of Aspergillus flavus on composting process of cotton waste for cultivation of paddy straw mushroom [Volvariella volvacea (Bull.) Singer 1951

Paddy straw mushroom [Volvariella volvacea (Bull.) Singer 1951] is a tropical edible mushroom and commonly cultivated in Indonesia. Composting process for preparing substrate plays an important role during mushroom cultivation. The purpose of this study is to investigate the effect of the addition of Aspergillus flavus, the lignocellulolytic fungi in the composting process of cotton waste for cultivation of V. volvacea. The result showed that there was an increase in temperature of compost of 27-58°C and pH of 7-8 for seven days observation. The concentration of cellulose, hemicelluloses and lignin was decreased from the 2nd days of the composting process in both the addition and without the addition of A. flavus. The highest concentration of glucose was 0.089 mg/mL without addition of A. flavus and 0.122 mg/mL with the addition of A. flavus. The highest concentration of xylose was 0.070 mg/mL without addition of A. flavus and 0.173 mg/mL with the addition of A. flavus. The fresh weight of the fruiting body of V. volvacea was 11.153 g and 9.395 g with the addition of A. flavus and without the addition of A. flavus in the composting process, respectively.

Exploitation of cellulose degrading bacteria in bioconversion of agro-wastes

The issue of solid waste management has become worse as a result of rapid demographic growth and rising urbanisation. Therefore economical, efficient and quick yielding techniques are essential. In this study, composting of agro-wastes i.e., paddy straw, maize stover and vegetable waste with three strains of cellulolytic bacteria (CBC9, CBD4 and CBG2) was performed. The results showed that the C:N ratio of matured compost produced from bacterial inoculation ranged from 14–17:1, nitrification index (NI) ranged from 0.35 to 0.45, Cation exchange capacity (CEC) ranged from 76 to 88 cmol (P+) kg−1, whereas, total N, P and K content of composts increased by 75–127 %, 20–175% and 42–94%, respectively. The recovery of compost was highest in case of paddy straw compost (39%) produced from CBG2 inoculation which was followed by vegetable waste (38%) and maize stover compost (36%) produced from same bacterial inoculation. FT-IR, SEM and EDS studies suggested that final compost produced from inoculation of bacterial strain was more stabilized as compared to un-inoculated control, characterized by a decrease in aliphatic materials and an increase in aromatic groups, presumably related to bio-synthesis of humic substance.

According to the observational data, the banana fruit's pH rose as it ripened, further from the present experimental findings. The best packaging material suitable for the enhancement of shelf life and maintenance of visual appearance and quality for bananas is low-density black polythene Treatment T1.

A Comparative Study of Various Substrate Combinations on Mass Multiplication of Trichoderma lexii (T-94a)

The high cost of raw materials has long hindered the large-scale commercialization of Trichoderma sp. conidiophore formulations. This study addresses the need for affordable, nutrient-rich alternatives by exploring the use of lignocellulosic residues, comprising lignin, cellulose, and hemicellulose, as a carbon source for cultivating Trichoderma. These fungi possess unique attributes, such as filamentous growth and prolific spore production, which make them valuable for composting lignocellulosic waste. Using different substrates with a combination of straws effectively helps in the decomposition of straw and enhances the mass multiplication of Trichoderma lexii (T-94a). Different substrates such as broken rice, grounded maize, gram flour, sorghum &amp; broken wheat were used in combination with paddy straws. A combination of Maize + straw induced an early response in the mycelial growth of Trichoderma lexii (T-94a). After 5 and 10 days of inoculation, physical parameters such as growth and sporulation characteristics of T. lexii (T-94a) show highly uniform growth and profuse sporulation on maize and straw combination as compared to broken rice &amp; straw, sorghum, and straw combinations. This finding has promising implications for improving agricultural practices and waste management. Further research can fine-tune the optimal substrate ratios to enhance the efficiency of biocontrol agents and waste decomposition. Scaling up the application of these substrate combinations in real-world farming scenarios and assessing their long-term environmental impact will be essential for realizing the full potential of these sustainable agricultural practices.

Watermoss Mulching Stimulates the Productivity and Physiochemical Properties of Strawberry in the Tropical Ecosystem of Southern Bangladesh

Strawberry is one of the most lucrative antioxidants and phytochemicals enriched temperate fruits. Nevertheless, good-quality fruit production requires special soil management practices like mulching and other strategies in tropical and sub-tropical regimes with short and dry winters. In the present research, strawberry var. BARI Strawberry-3 was cultivated using Asian watermoss (AW), water hyacinth (WH), paddy straw (PS), black polythene (BP), and silver polythene (SP) mulching along with control at the tropical weather-inclined southern part of Bangladesh from October 2018 to April 2019. The aim was to evaluate the comparative influences of those organic and synthetic mulches on root and shoot growth phenology along with subsequent reproductive behaviors, fruit yield, and fruit biochemical properties of strawberries under such an ecosystem. The experiment was conducted in a randomized complete block design with four replications. Mulching exhibited statistical superiority over control for strawberry growth, yield, and fruit quality indicators, where organic mulches performed better than others. Among the mulches, AW mulching produced the healthiest plant, having maximum plant height (20.40 cm), leaf number (23.33 per plant), canopy diameter (34.30 cm), single leaf area (100.06 cm2), and root length (19.05 cm) resulting in the highest root and shoot biomass. Though the plants received AW mulch required maximum duration from transplanting to flowering (47.88 days) and flowering to harvest (29.60 days), those plants produced the highest number of flowers (21.20 per plant) as well as fruits (19.63 per plant), and ultimately the utmost fruit yield (370.02 g/plant and 15.42 kg/ha) being significantly dissonant from all other treatments. Thus, a 57.57% yield increase over control was recorded from AW mulching. Furthermore, statistically, the maximum total soluble solids (TSS) (9.93%), TSS/acidity ratio (17.37), and vitamin C (58.30 mg/100 g), but the minimum titratable acidity (0.57%) content of strawberry was noticed in AW treatment. WH and BP mulches had statistical consistency with the best treatment for a few attributes. Therefore, crop residues, aquatic plants, or their by-products can be used as mulch for quality strawberry production in dry winter, especially in tropical and subtropical regions.

Effect of Integrated Nitrogen and Mulching on Growth, Yield and Quality Characteristics of Broccoli (Brassica oleracea var. italica) cv. Palam Samridhi

Broccoli is an important cole crop, widely grown in India. The excessive use of inorganic fertilizer, resulting in infertility of soil and chemically toxic agricultural by-products, is one of the most limiting factors affecting the quality production and productivity of the crop. To evaluate the effect of different organic and inorganic nitrogen sources and the application of different mulching materials on productivity and quality aspects of broccoli cv Palam Samridhi, the experiment was conducted for two years during 2021-22 and 2022-23. Among the treatments, the highest plant height (36.12cm), leaf length (22.39cm), leaf width (13.30), stem diameter (2.5), plant spread (1687.60cm2), head weight (367.75g), head yield/ha (254.43q/ha), moisture (91.65%), TSS (8.10°B), head dry matter (12.54%) and protein (3.65%) were recorded in treatment N5M2 (50% Nitrogen with Urea (108kg/ha) along with 50% Nitrogen utilizing Poultry Manure (1.5t/ha) and black polythene mulch) and quality traits such as highest chlorophyll (19.83%) in N3M2 (50% N Urea(108kg/ha)+50% N FYM (10t/ha) + Black Polythene mulch). In contrast, Proline (36.58%) were recorded in treatment N4M1 (50% N Urea (108kg/ha) +50% N Vermicompost (4t/ha) + Paddy Straw mulch), which was found superior overall individual treatments and their combination.

Development of biodegradable tableware from novel combination of paddy straw and pine needles: A potential alternative against plastic cutlery

Plastic cutlery for food packaging and serving has long been in trend due to its versatile properties but accumulation of the single use plastic cutlery creates disposal problem due to its non-biodegradability. The two biomasses paddy straw and pine needles are known to cause serious problems of stubble burning and forest fires respectively. However, these two biomasses hold tremendous potential to be used as raw material in pulp industry due to their high holocellulose and cellulose content which can be further enhanced after pre-treatments. This study aims to use a combination of two biomasses in a ratio of 1:1 and further process it to derive pulp by employing enzymes such as laccase, manganese peroxidase, and lignin peroxidase for lignin removal by fermentation mechanism. After sufficient lignin removal, the processed beaten pulp was casted into cups and bowls. Binding agents such as carboxymethyl cellulose, gum acacia and potato starch along with cross-linking polymer were blended with pulp in binding matrix to cast durable and non-brittle biodegradable cups. PLA (bio-plastic) polymer was applied in the form of a thin film over the developed tableware. The developed tableware was further verified for anti-microbial properties by testing it with common food-poisoning pathogens. Mechanical stiffness and rigidity were estimated along with thermal stability examined over a wide temperature range by dynamic scanning colorimetric (DSC). Lattice structure and morphology was studied by SEM and XRD analyses. Based on the analytical analyses, the developed biodegradable tableware can be a suitable alternative to combat plastic cutlery menace.

Effect of mixing paddy straw with molasses and urea on fermentation characteristics and nutritive value of maize silage

The present investigation was aimed at studying the improvement of fermentation and nutritive quality of rice straw-maize silage by the inclusion of different additives. In the experiment, paddy straw and green maize fodder were mixed in ratios of 100:0, 75:25, 50:50, 25:75, and 0:100 for silage preparation. These combinations were made in a triplicate and added with no additive (C), 2% urea (T1), 1% molasses (T2) and a mixture of 2% urea and 1% molasses (T3) in completely randomized design (CRD). The silages were harvested after 45 days and then analyzed for chemical composition, fermentation characteristics and anti-nutritional factors. Results revealed that dry matter (DM), acid detergent fibre (ADF), neutral detergent fibre (NDF), crude fibre (CF), ash and pH increased with an increase in the proportion of paddy straw in all combinations. Addition of 2% urea increased in vitro dry matter digestibility (IVDMD), crude protein (CP) and total gas production (TGP) of paddy straw and maize fodder silage. Urea treatment considerably reduced the oxalate content and increased the tannin content of paddy straw and maize fodder silage. In the present study, silage prepared by combining paddy straw and maize fodder in ratio of 25:75 had good aroma and fermentation characteristics which can be, therefore, utilized for effective silage making.

Biochar for Improving Growth Performance of Shrimp and Environmental Quality in an Inland Saline Culture System.

The current study, which lasted 45 days, was designed to find a more effective way to use the vast resources of salt-affected land and ground saline water for aquaculture. Biochar made from agrowaste was used as a sediment amendment. The 100 g of biochar was applied to 25 kg of sediment (i.e., 9.0 ton ha-1) in 300L capacity fiber reinforced plastic, and Penaeus vannamei (P. vannamei) (2.74 ± 0.03 g) was stocked at 90 juveniles m-2 in inland ground saline water of salinity 10 ppt fortified with potassium levels that are 50% equivalent to those of seawater. Among different treatments, T1 indicates paddy straw biochar (PSB) application in sediment; T2 indicates sediment amended with KOH-activated PSB; T3 indicates sugar cane bagasse biochar (SBB) application in sediment; and T4 indicates sediment amended with KOH-activated SBB. Compared to the control the potassium (K+), alkalinity, total hardness, calcium/magnesium ratio, and pH of the water increased significantly (P ≤ 0.05) in treatments where biochar was used as an amendment in sediment. The T3 treatment had the best Ca/Mg ratio (1.00:3.12). In water, the magnitude of increase in K+ concentration from high to low followed the order: T2 > T4 > T1 > T3 > control. The concentration of NH4+-N in water was found to be increasing in control, whereas in the rest of the treatments, it decreased significantly from day 1, until the end of the experiment. Compared to control, the bulk density was decreased, and sediment cation exchange capacity and water holding capacity were increased significantly in treatments where biochar was used as an amendment. The soil microbial parameter measured in terms of soil enzyme dehydrogenase was significantly different among treatments at the end of the experiment. Weight gain (%), specific growth rate (SGR), survival (%), and feed conversion ratio of P. vannamei varied significantly in T1, T2, T3, and T4 compared to the control. The SGR (2.38b ± 0.05% day-1) and weight gain (%) in T2, and survival (96.1b ± 2.0%) in T3 treatment were found to be the highest at the end of the experiment. When biochar was mixed with sediment in the inland saline system, an improvement was seen in sediment quality, water quality, and growth characteristics of P. vannamei.

Utilization of mill rejects with biomass pellets in the existing coal power plants- a novel approach towards sustainability & fuel security

ABSTRACT The present work is focused on the possible utilization of mill rejects blended with the biomass non-torrefied pellets (made of paddy straw, dry grasses and fallen sal leaves) in the existing tangential coal-fired boiler through the gasification process. The physio-chemical analysis and combustion behavior study of the materials is done based on thermo-gravimetric analysis (TGA) and differential thermal analysis (DTA). The result shows that the gross calorific value (GCV) of the developed bio-mass pellet is about 3900–4300 kCal/kg with the mass percentage of fixed carbon (FC) and volatile matter (VM) of about 15% and 70%, respectively. From the TGA and DTG study, it is observed that about 7% weight loss was found in all pellets at a temperature range of about 85–110°C but for the mill rejects, it is about 5–6%. At the peak temperature, the maximum weight loss of pellets and mill rejects is about 0.90 gm/min and 0.16 gm/min, respectively. The combined use of mill rejects and pellets (1:1) in the updraft gasifier generates combustible syngas with mole fractions of CO and H2 of about 0.29 and 0.30, respectively with a lower heating value of about 159 kJ/mole. The direct use of generated combustible syngas into the coal-fired boiler of a 500 MW power plant increases the net energetic and exergetic performance by about 0.09 and 0.07% points, respectively and resulting in a reduction of annual CO2 emissions by about 9452 tons. Cost-benefit analysis is used to determine the feasibility of the system.

Effect of Different Litter Materials on Behavior, Stress and incidence of Mortality and Morbidity rate on Broiler Chickens

The goal of the current study was to find out effect of different litter materials on behavior, stress and incidence of mortality and morbidity rate on broiler chickens. The Poultry Unit of Livestock Farm Complex of the College of Veterinary Science and Animal Husbandry, ANDUAT Kumarganj, Ayodhya, UP, served as the study’s location. For a total of 42 days (6 weeks), the experiment was conducted on 240-day-old Vencobb400 straight run commercial broiler chicks. After being weighed, the chicks were divided at random into three treatment groups: Group 1 (Control – Rice husk) is denoted by (Tc), Group 2 (50 % Rice husk + 50 % Paddy straw) is denoted by (T1), and Group 3 (Wood saving) is denoted by (T2). Each treatment group consisted of two replicates, each with 40 chicks. The experiment’s findings indicate that T1, or the treatment groups that received both paddy straw and rice hulls, had lower feeding rates and duration. However, throughout the course of the weeks, there were no significant differences in the frequency or percentage of time spent engaging in certain behaviors across the three groups. At age 6, the H/L ratio was higher in the Tc group (0.37a ± 0.008) than in the T1 group (0.33b ± 0.456) or T2 group (0.35a ± 0.120). According to this study, birds in the T1 group experienced the least amount of stress compared to other treatment groups. The broiler chick mortality rate was 6.25% in the wood-saving litter (T2) and 3.75% in the T1 group, followed by 5% in the Tc group.

Validation, dissipation kinetics and monitoring of flonicamid and dinotefuran residues in paddy grain, straw, its processed produces and bran oil using LC-MS/MS

Flonicamid and dinotefuran are highly effective insecticides in paddy but residue persistence in crop and transmission into food and feed is unknown. This study aimed to examine initial deposits and dissipation kinetics of flonicamid and dinotefuran in paddy matrices and processed products including bran oil. The method was validated following acetonitrile extraction, dispersive solid phase clean-up and finally determination using liquid chromatography-mass spectrometry/mass spectrometry. Recoveries ranged from 76.6 to 109.7 percent for the paddy matrices tested. In a field experiment, flonicamid and dinotefuran were applied to paddy crops to study dissipation patterns. The half-lives of flonicamid and dinotefuran residues in paddy ranged from 2.0 to 3.0 days. However, at harvest time paddy grain and straw samples were found free from residues. Monitoring of residues in farm gate and market samples revealed that paddy products were not contaminated with flonicamid or dinotefuran residues.

The present experiment was conducted at Sahiwal Cattle Farm, College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, Assam, India for a period of 120 days from July to November, 2022. to investigate the effect of supplementing garlic powder (Allium sativum) on the performance of Sahiwal calves. Twelve healthy Sahiwal calves of both sexes of similar age and body weight were allocated to two experimental groups, control and treatment with six animals in each group. Calves of both groups were fed with a standard basal diet consisting of concentrate, green fodder, and paddy straw. While in the treatment group, garlic powder was supplemented @ 250 mg kg-1 body weight along with concentrate feed. The experiment was conducted as a feeding trial for eight fortnights and a digestibility trial thereafter for five days in the two experimental groups. The statistical analysis revealed a highly significant differences (**p&lt;0.01) in body weight of the calves, fortnightly body weight gains up to 8th fortnight and the dry matter intake of the calves. Statistical analysis also revealed highly significant (**p&lt;0.01) differences in the conformation traits when compared between the groups with highly positive correlation with the body weight of the calves. Further it can be concluded that the supplementation of garlic powder at dosage of 250 mg kg-1 body weight in the Sahiwal calf ration is beneficial in terms of body weight gain, feed conversion ratio, body confirmation traits, and economic of feeding.

Biomass potential from agricultural residues for energy utilization in West Nusa Tenggara (WNT), Indonesia

AbstractThe West Nusa Tenggara (WNT) province is one of the regions that contribute the most to the production of rice, corn, and cacao. The residues of these crops increase as production increases. The potential availability of the residue was calculated on the basis of the amount of agricultural product and the availability of unutilized residues. The estimated potential energy and collected data were processed and combined with converted factors, such as the yield per hectare and the calorific value, taking into account another purpose, the use of domestic residues for animal feed. Paddy straw, corn straw, and corn cobs had the highest percentage of residue availabilities, 85.91%, 82.26%, and 88.25%, respectively. In addition, the WNT regency has a rich diversity of agricultural residues from superior commodities such as rice, corn, coffee, coconut and cacao. The calculation of the total heating value (THV) of the agricultural residue available reached up to 42.4 PJ. Furthermore, the use of biomass for bioenergy resources is promising, particularly for the WNT region, with the potential for unused agricultural residues. The dependence on unsustainable energy, such as coal and fossil fuel, can be reduced by deploying and developing energy production from biomass use. Therefore, the potential for bioenergy generation and the availability of biomass can be developed for sustainable agriculture and energy management.
