Allelopathic Effects of Residues of Fimbristylis dichotoma Along with Manures and Fertilizers on the Weed Growth in Boro Rice

Currently, the rice-growing system seeks a biological solution to reduce the negative impacts of chemical herbicides because it is heavily reliant on these for weed control. This is where allelopathy comes in; it's a potential substitute for conventional weed management strategies in rice cultivation by making use of allelopathic plant residues. In the study we used Fimbristylis dichotoma residues with several organic sources of nutrient to measure the integrated effect of manures, fertilizers, and Fimbristylis dichotoma residues on weed growth in boro rice field. Two rice varieties viz., BRRI dhan29 and BRRI dhan89; and six treatments total viz., Control (T1), Residues @ 3 t ha-1 + Recommended doses of inorganic fertilizers (T2), Residues @ 3 t ha-1 + Tricho-compost @5 t ha-1 (T3), Residues @ 3 t ha-1 + Tricho-compost @1.5 t ha-1 + 25% less than recommended doses of inorganic fertilizers (T4), Residues @ 3 t ha-1 + Tricho-compost @2.5 t ha-1 + 50% less than recommended doses of inorganic fertilizers (T5) and Residues @ 3 t ha-1 + Tricho-compost @3.75 t ha-1 + 75% less than recommended doses of inorganic fertilizers (T6) were taken. In the experiment, at 25 DAT (days after transplanting), BRRI dhan89 had the highest weed density (35.0) when no residue was applied, and BRRI dhan29 had the lowest (18.00) when 3 t ha-1 F. dichotoma residue with Tricho-compost @ 1.5 t ha-1 + 25% less than recommended doses of inorganic fertilizers were applied. At 55 DAT, BRRI dhan89 had the highest weed density (19.66) when no residue was administered, and the lowest (10.66) when 3 t ha-1 F. dichotoma residue was applied along with Tricho-compost @ 1.5 t ha-1 + 25% less than recommended doses of inorganic fertilizers. When it came to dry weight, at 25 DAT, BRRI dhan89 had the highest weed dry weight (3.76 g) when no residue was applied, and BRRI dhan29 had the lowest (1.72 g) when 3 t ha-1 F. dichotoma residue with Tricho-compost @1.5 t ha-1 + 25% less than recommended doses of inorganic fertilizers were applied. At 55 DAT, BRRI dhan89 had the highest weed dry weight (2.29 g) when no residue was sprayed, and the lowest (1.46 g) when 3 t ha-1 F. dichotoma residue with Tricho-compost @ 1.5 t ha-1 + 25% less than recommended doses of inorganic fertilizers were applied. The study's findings suggest that applying F. dichotoma residue and incorporating Tricho-compost @ 1.5 t ha-1 + 25% less than the recommended amounts of inorganic fertilizers may be able to suppress the growth of weeds and could a package in biological weed control strategy.

Comparative study on productivity of Hybrid Napier CO3 and CO4 with the application of organic and inorganic fertilizers

The present study aimed to assess the growth parameters, herbage yield and chemical composition of CO3 and CO4 (Pennisetum perpureum X Pennisetum americarnum) at the Livestock farm Eastern University, Sri Lanka from July to September 2018. Four different treatments; inorganic fertilizer 100%, Organic fertilizer 100%, Control and Inorganic+Organic fertilizer 1:1 (weight basis). Plant height, leaf length, number of tillers per clump, leaf area, yield and total ash content were measured at two-week intervals from the 4th week up to the 8th week and data were subjected to Analysis of Variance (ANOVA). The means were separated using Duncan’s multiple range test at 0.05 significance level. Results indicated that the productivity of CO3 is superior to CO4 in terms of growth and yield under (T4) CO3 with 1:1 mixture of inorganic and organic fertilizer. The highest (p<0.05) fresh matter yield of 18.07 t/ha, with a dry matter yield of 3.83 t/ha was recorded in the sole application of inorganic fertilizer. A similar yield was obtained in CO3 with the 1:1 inorganic and organic fertilizer mixture. CO3 showed the highest total ash content (18.44%) on dry matter basis. Hence, farmers can save half of the cost of inorganic fertilizer by using farmyard manure along with half of the recommended dose of inorganic fertilizer for fodder cultivation

Potential of cattle urine as an alternative fertilizer for maize (Zea mays L.) production in Ethiopia

Maize productivity has been increasing through the years due to increased use of inorganic fertilizers. However, the price and environmental impact has brought lack of interest among the farmers. Thus, this study was aimed at evaluating the growth, yield and nitrogen use efficiency (NUE) of maize varieties under cattle urine application. The field experiment was conducted in randomized complete block design with three replications. The experiment consisted of four treatments viz. control, 100 and 50 % cattle urine and recommended dose of inorganic fertilizer. The results demonstrated a comparable growth and grain yield increment due to 100 % cattle urine and recommended dose of inorganic fertilizer. The difference between the two varieties in growth, yield and related traits, and NUE indices due to fertilizer applications was insignificant. The leaf area of maize nourished with 100, 50 % cattle urine and recommended dose of inorganic fertilizer increased by 11.15, 9.73 and 9.78 folds, respectively, in two months period relative to the controls. Fertilized plants had significantly (p < 0.05) higher grain yield (GY). The use of 100, 50 % cattle urine and inorganic fertilizers resulted in 526.76, 326.12, 542.91 % and 47.83, 36.03, 49.78 % increment in average GY and aboveground biomass, respectively, compared to controls. Similarly, plants fertilized with 50 % cattle urine showed an average GY reduction of 39.87 and 38.10 % compared to the recommended dose of inorganic fertilizer and 100 % cattle urine, respectively. The use of 50 % cattle urine produced significantly higher NUE, N agronomic efficiency (NAE), N recovery efficiency (NRE) and internal efficiency (IE). Higher GY kg-1 of N applied was obtained from cattle urine applications. In a nutshell, the results confirmed the potential of cattle urine as an alternative to inorganic fertilizers in maize production. However, further studies on optimization of the cattle urine rate and scale up works are recommended.

Integrated effect of bio-slurry with chemical fertilizers on the performance of mustard varieties

To assess the importance of bio-slurry in combination with chemical fertilizers on the yield of mustard, a field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh. Four varieties of mustard (BARI sarisha-14, BARI sarisha-11, BARI sarisha-13, Tori-7) along with four fertilizers treatments i.e. control, recommended dose of inorganic fertilizer, bio-slurry @ 5 t ha-1 + inorganic fertilizer, farmers’ practice (average of 15 farmers) was included in this study. The experiment was set up employing randomized complete block design with three replications. The result revealed significant varietal effects on all the yield and yield contributing characteristics. BARI sarisha-13 exhibited the highest seed yield (2.37 t ha-1), which can be attributed to increased branches plant-1, siliqua plant-1 and seeds siliqua-1. Fertilizer treatments significantly affected different yield parameters and yield. Among them, bio-slurry @ 5 t ha-1 + inorganic fertilizer produced the highest seed yield (1.83 t ha-1), while the control yielded the lowest (1.63 t ha-1). The integrated effect of varieties and fertilizers showed promising results. BARI sarisha-13 with bio-slurry @ 5 t ha-1 + inorganic fertilizer produced the highest seed yield (2.56 t ha-1). Therefore, it could be concluded that BARI sarisha-13 with bio-slurry @ 5 t ha-1 + inorganic fertilizer has the potential for maximizing mustard yield. Res. Agric. Livest. Fish.

Enhancing soil fertility, inorganic fertilizer efficiency, and oil palm productivity through bio-compost application in oxium biodegradable sacks on former mining land-podzols: Insights from a field study in Indonesia

Sandy podzolic soils, prevalent on former mining lands, present significant agricultural challenges due to their coarse texture, depth, acidity, and low fertility. This study evaluated the impact of bio-compost fertilizer, delivered in biodegradable oxium sacks, on soil quality and oil palm productivity in these soils. Conducted over 12 months in a 4-year-old oil palm plantation in East Belitung Regency, Indonesia, the research compared various combinations of bio-compost and inorganic fertilizers with a control group. The findings revealed that the integration of bio-compost with reduced doses of inorganic fertilizers markedly improved soil quality and decreased dependence on chemical inputs. Specifically, applying 50 kg or 75 kg of bio-compost per palm along with 50 % or 75 % of the standard inorganic fertilizer dose was particularly effective. This approach increased oil palm productivity to 14.50–15.87 tons per hectare per year. The method provides a sustainable solution for the palm oil industry and small farmers, improving soil fertility and productivity in degraded podzolic soils. The use of oxium biodegradable sacks allowed for a gradual release of nutrients. Future research should further explore the potential of bio-compost as a soil conditioner and its long-term environmental impacts across various soil types.

Responses of Soil Enzymes Activities to Sprinkler Irrigation and Differentiated Nitrogen Fertilization in Barley Cultivation

Our study aimed to assess the impact of sprinkler irrigation on the activity of selected soil enzymes in terms of nitrogen metabolism and oxidation–reduction processes in soil with different doses of inorganic nitrogen fertilizers. An Alfisol was sampled from an experimental field of spring barley within the University Research Center in the central part of Poland, namely the village of Mochełek with a moderate transitory climate, during the growing seasons of 2015–2017. The soil resistance (RS) was derived to recognize the resistance enzymes during drought. In the maturity phase, nitrate reductase activity was 18% higher in irrigated soil and the activities of other enzymes were higher than in the non-irrigated plots by 25% for dehydrogenase, 22% for peroxidase, 33% for catalase, and 17% for urease. The development phase in the barley influenced nitrate reductase activity. Enzymatic activities changed throughout the research years. During the maturity stage, a lower ammonium nitrogen content in the soil resulted from a higher spring barley uptake due to drought stress. Irrigation probably contributed to increased leaching of nitrate in the soil. The highest index of resilience was found in the soil catalase activity.

Effect of Integrated Nutrient Management in China Aster cv. Arka Poornima Under Mid Hills of Himalayas

The present investigation was conducted to investigate the effect of integrated nutrient management on vegetative parameters of China aster cv. Arka Poornima under the mid hills of Himachal Pradesh. The experiment was laid out in simple randomized design (RBD) with eighteen treatments. The experiment was conducted at the Kakhali research farm of Dr. Khem Singh Gill Akal College of Agriculture, Eternal University, Baru Sahib, Himachal Pradesh during kharif season in 2023. For integrated nutrient management eighteen treatments were constituted with three levels of recommend dose of inorganic fertilizers (50, 75 and 100 %) and three biofertilizers viz., Azotobacter, PSB and KSB along with control. The observations for the vegetative parameters plant height (cm) at maturity, numbers of leaves, number of primary branches, number of secondary branches, leaf area per plant, leaf area index and plant spread were recorded and analyzed. The plant height (91.40 cm), No. of leaves (356.13), No. of primary branches (12.40) and secondary branches (33.70) were found maximum in treatment T12 (RDF@75% + Azotobacter + PSB + KSB), while the lowest values were observed in T0 (control). The highest leaf area (27.49 cm2) was found in T8 (RDF@75% + Azotobacter), while the leaf area index (12.02) and plant spread (16.57 cm) were found in treatment T11 (RDF@75% + Azotobacter + PSB). The lowest values for leaf area (17.77 cm2), leaf area index (5.48) and plant spread (11.82 cm) were found in treatments T14 (RDF@100% + Azotobacter), T16 (RDF@100% + KSB) and T10 (RDF@75% + KSB), respectively. Therefore, it can be concluded that, application of T12 (RDF@75% + Azotobacter + PSB + KSB) is best for the getting higher production in China aster followed by T11 (RDF@75% + Azotobacter + PSB). This study will reduce the use of inorganic fertilizer without polluting the soil and environment.

Kombinasi Pupuk Anorganik dan Pupuk Organik Meningkatkan Produksi Tanaman Tomat (Licopersicum esculentum Mill) dengan Pemangkasan Pucuk Apikal

The research aims to determine the effect of a combination of inorganic fertilizer (KNO3) and organic fertilizer (goat manure) on the yield of the Betavila variety when apical shoots are pruned. The research took place from March to October 2019 in Kupang Regency, NTT. The research used RAK with 4 repetitions. The treatments are as follows: M1 = inorganic fertilizer 5 g/l KNO3; M2 = organic fertilizer 20 tons/ha goat manure; M3 = inorganic fertilizer 5 g/l KNO3 + organic fertilizer 30 tons/ha goat manure; M4 = inorganic fertilizer 5 g/l KNO3 + organic fertilizer 15 tons/ha goat manure; M5 = Inorganic fertilizer 3.75 g/l KNO3 + organic fertilizer 15 tons/ha goat manure; M6 = Inorganic fertilizer 3.75 g/l KNO3 + organic fertilizer 30 tons/ha goat manure; M7 = inorganic fertilizer 2.5 g/l KNO3 + organic fertilizer 15 tons/ha goat manure; M8 = inorganic fertilizer 2.5 g/l KNO3 + organic fertilizer 30 tons/ha goat manure. The results of the research showed that the combination of applying inorganic fertilizer and organic fertilizer simultaneously influenced the yield of Betavila variety tomato plants whose apical shoots had been pruned, namely on the number of fruits, fruit weight, and fruit production. Fertilization dose of inorganic fertilizer 3.75 g/l KN03 + organic fertilizer 30 tons/ha goat manure gave the number of fruits per plant (59.63 fruit), fruit production per plant (2.63 kg), and fruit production per experimental plot (50.33 kg) highest.

Compost as an Alternative to Inorganic Fertilizers in Cowpea [Vigna unguiculata (L.) Walp.] Production

ABSTRACTSoil fertility management is essential to sustain agricultural production in smallholder farming systems. An experiment was carried out to assess the viability of the combined use of compost and inorganic fertilizers as an alternative to conventional inorganic fertilization under greenhouse conditions. The 10 treatments, arranged in a randomized complete block design (RCBD) with six replications, consisted of a control, conventional mineral fertilization (150 kg NPK ha−1), composts added to the soil alone (2.5, 5, 7.5, and 10 t ha−1), and their combination with 50% of recommended rate of inorganic fertilizers (75 kg NPK ha−1). Application of 7.5 t ha−1 of compost and 50% of the recommended dose of inorganic fertilizer (75 kg NPK ha−1) gave the significantly highest seed yield, corresponding to a 30% increase over NPK‐fertilized plants. The combined application of 2.5 or 10 t ha−1 compost with 75 kg NPK ha−1 increased plant height by 38% compared with the NPK treatment. Additionally, stem diameter increased by 53% when 5 t ha−1 of compost and 75 kg NPK ha−1 were mixed. As expected, control plants produced the most nodules (108), 85% more than inorganic fertilization. Plants fertilized with 7.5 or 10 t ha−1 of compost and 75 kg NPK ha−1 produced 17% more pods, seeds per pod, and seeds per plant than NPK treatments. However, fertilization treatments had no significant effects on cowpea fresh and dry biomass or SPAD values. The results reveal that combining compost with inorganic fertilizer reduced synthetic fertilization by 50%, while producing growth and yields comparable to, or even higher than, recommended inorganic fertilization. This experiment demonstrated that integrated soil fertility management can be used as an alternative to the use of inorganic fertilizers in cowpea cultivation.

Growth Performance of Neem (Azadirachta indica) Seedlings as Influenced by Organic and Inorganic Fertilizers

A pot experiment was carried out in the net house of the Department of Soil, Water and Environment, University of Dhaka. The aim of the study was to assess growth and yield performance of Neem seedlings with the different doses of organic and NPK fertilizers. Trichocompost (TC) was used as organic fertilizer. The treatments used in the experiment were: T1: Control (-OM and -NPK), T2: TC (10 ton/ha), T3: TC 5 ton/ha, T4: NPK 100% RDF, T5: NPK 80% RDF + TC 5 ton/h, T6: NPK 60% RDF + TC 5 ton/h, T7: NPK 40% RDF + TC 5 ton/h, T8: NPK 80% RDF + TC 10 ton/h, T9: NPK 60% RDF + TC 10 ton/h, T10: NPK 40% RDF + TC 10 ton/h. Pots were arranged in a Completely Randomized Design (CRD). Plant height and the number of leaves per plant were recorded at a 15-day interval. The tallest plant (78.87 cm) observed with the application of sole Trichocompost 5 ton/ha. Incremental dose of TC and inorganic fertilizer reduces the height of plant. The maximum no. of leaves ( 51.67) was found with NPK 60% RDF + TC 5 ton/h at the stage of 90 days and the next highest amount of leaves (44.67) with NPK 80% RDF + TC 10 ton/h at 90 days after. The lowest height (12.52 cm) and leaf number/plant (8.33) were recorded in control. Maximum fresh and dry weights (root, bark, and leaf) were 17.19 g/plant and 6.24 g/plant, respectively, found in T8: (NPK 80% RDF + TC 10 ton/h). The best growth performance of seedlings was observed in T8: NPK, 80% RDF, and TC 10 ton/h .The research indicated that there was no significant treatment difference on nutrient uptake by the neem seedlings.

Organic Farming vs. Integrated Nutrient Management: A Comparative Review of Agricultural Productivity and Sustainability

In an era where sustainable agriculture is crucial for global food security and environmental preservation, organic farming and Integrated Nutrient Management (INM) have emerged as leading practices. This review paper offers a comprehensive comparison of these two approaches, focusing on their impact on agricultural productivity and sustainability. Organic farming, with its emphasis on reducing the use of chemical fertilizers, pesticides, growth hormones, and feed additives, aligns closely with the principles of sustainability. It enhances food quality, promotes soil health, and mitigates adverse environmental effects by encouraging natural recovery cycles. However, organic farming's limitations, such as lower yields and a more labour-intensive approach have prompted interest in innovative solutions that blend organic practices with modern technologies. Integrated Nutrient Management (INM) presents a compelling alternative. By combining organic, inorganic, and biological nutrient sources, INM seeks to optimize nutrient use efficiency and maintain soil health. This approach offers a flexible nutrient management strategy, balancing organic and inorganic inputs to maintain crop productivity while reducing environmental impact. Studies have shown that INM can improve soil properties, such as bulk density, porosity, and water-holding capacity, leading to enhanced crop yields and lower greenhouse gas emissions. The paper explores how INM's integrated approach not only stabilizes crop production but also supports the growth of soil microbes, providing a source of energy and organic carbon. By using a combination of specific microorganisms, organic matter, and minimal doses of inorganic fertilizers, INM can achieve a harmonious balance that reduces environmental pollution and ensures long-term soil fertility. Ultimately, this review underscores the potential of combining organic and INM practices to create a sustainable and productive agricultural system. Through a comparative analysis, the paper aims to guide researchers, policymakers, and farmers towards adopting strategies that foster agricultural sustainability without compromising productivity.

Influence of Integrated Nutrient Management Practices on Soil Fertility and Yield of Fodder Maize in Chennai

Field experiments were conducted to study the influence of fodder maize (Zea mays L.) by adopting different bulky organic manures and fertilizer levels on the soil fertility status and fodder yield of maize. The study was conducted during rabi season of 2019 and 2020 at the Department of Agronomy, Madras Veterinary College, Chennai. An experiment was laid out in split plot design. Main plots consisted of different organic manure treatments viz., No manure, farm yard manure (25 t ha-1), vermicompost (12 t ha-1) and poultry manure (12 t ha-1). Sub plots consisted of varying level of fertilizer treatments viz., No fertilizer, 125% RDF, 100% RDF, 75% RDF. The blanket recommendation of fertilizer to fodder maize is 60 kg N ha-1: 40 kg P2O5 ha-1: 20 kg K2O ha-1. The organic manures were applied as per the N equivalent basis to inorganic nutrient recommendation. The results revealed that all the soil parameters, green and dry fodder yield were significantly affected with the application of organic manures and fertilizer levels. Organic sources of nutrients tended to improve soil physico-chemical properties viz., bulk density, water holding capacity, porosity and organic carbon. The highest organic carbon content was noticed with the application of poultry manure (0.50 %) followed by poultry manure. The post harvest available soil nutrients was high in fodder maize grown with poultry manure along with 125% recommended dose of inorganic fertilizer to fodder maize recorded higher soil available nitrogen (109.48 kg ha-1), phosphorus (15.46 kg ha-1) and potassium (118.65 kg ha-1). Significantly higher green and dry fodder yield of maize was recorded with application of poultry manure along with 75 % recommended dose of fertilizer. Hence, application of organic manures specifically poultry manure along with low level of fertilizer improved the soil fertility and thus increased the green fodder yield of maize.

Effect of Hairamin and Fertilizer Application on Grain Yield and Its Attributes in Wheat (Triticum aestivum L.) Varieties

A field experiment was conducted at the Research farm of the Department of Agriculture, Maharishi Markandeshwar University, Mullana, Ambala during Rabi season of 2021. Response of three wheat varieties to integrated nutrient management involving Hairamin (protein hydrolysate from human hair) and inorganic fertilizers (NPK) for grain yield and its attributes was studied in a field experiment. The soil was sandy loam, well-drained, alkaline (pH 7.23), low in nitrogen, medium in phosphorus, and high in potassium, with an electrical conductivity of 0.89 d/Sm. Eight treatments comprising a control and seven combination application of Hairamin, Azotobecter and recommended dose of inorganic fertilizers were evaluated in three wheat varieties “DBW 222", "HD 2967" and "PBW 723” in a randomized block design (RBD) with three replications. The T7 treatment, 75% recommended N, P, K dose throughout synthetic fertilizers and appropriate dose of Hairamin foliar spray, exhibited highest grain yield, biological yield and harvest index. This treatment was shown to be statistically comparable to T6 (50% recommended N, P, K dose throughout synthetic fertilizers and appropriate dose of Hairamin Foliar spray). This increase in yield was reflected in higher expression of yield attribute in traits namely (ears per running meter row length, spikelets ear-1, grains ear-1, 1000 grain weight, grain yield, straw yield, biological yield and harvest index). Therefore, use of Hairamin as bio-stimulant with reduced fertilizer doses is recommended for sustainable wheat production.

The variables observed were: plant height, number of leaves, leaf lenght, leaf width and wet weight. The results showed that the interaction between water hyacinth liquid organic fertilizer and inorganic fertilizers had an effect on the fresh weight of mustard green plants and had no effect on plant height, number of leaves, leaf length dan leaf width of mustard green plants.

Effect of various doses of inorganic fertilizers on growth and yield of dragon fruit (Hylocereus polyrhizus L.) in Assam condition

The present study was carried out in five Krishi Vigyan Kendras of different districts of Assam, viz. Dibrugarh, Jorhat, Nagaon, Nalbari and Chirang; to standardize the fertilizer requirement by dragon fruit plants in Assam condition. The growth and yield parameters recorded over two years revealed that the growth as well as the yield attributing characters were significantly influenced on application of Urea: SSP: MOP @70: 90: 40 g per plant in first year followed by Urea: SSP: MOP @ 150:150:300 g per plant from second year onwards (Treatment T2 ) as compared to the other treatments such as T0 : Control, T1 : 53:68:30 Urea, SSP, MOP g/plant(1st year) and 113:113:225 Urea, SSP, MOP g/plant (2nd year) and T3 : 88:113:50 Urea, SSP, MOP g/plant (1st year) and 188:188:375 Urea, SSP, MOP g/plant (2nd year).The Maximum stem diameter of 6.3 cm after 2nd year of establishment was found on application of T2 dose along with the maximum number of fruits per pole (25.82), maximum average fruit weight (272.04 g) and highest annual yield per pole (7.103 kg) as well as maximum fruit volume (279.6 cc) and the highest pulp: peel ratio (4.11). Therefore, considering the significance of T2 dose of fertilizer in various districts of Assam, it can be concluded that treatment T2 can be considered as the appropriate dose of fertilizer to be considered for Assam condition.

Integrated effect of manures and fertilizers with the allelopathy of Fimbristylis dichotoma (L.) on the yield performance of rice

Allelopathy plays an important role in weed control and crop productivity. In light of these, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh under the Old Brahmaputra Floodplain (AEZ-9) during the period from July 2021-June, 2022 to assess the combined effect of Fimbristylis dichotoma residues with manures and fertilizers on rice yield performance in boro season. The experiment consisted two rice varieties viz., BRRI dhan29 and BRRI dhan89; and six treatments of the combination of residues with manures and fertilizers viz., Control; Residues @ 3 t ha-1 + Recommended doses of inorganic fertilizers; Residues @ 3 t ha-1 + Tricho-compost @5 t ha-1; Residues @ 3 t ha-1 + Tricho-compost @1.5 t ha-1 + 25% less than recommended doses of inorganic fertilizers; Residues @ 3 t ha-1 + Tricho-compost @2.5 t ha-1 + 50% less than recommended doses of inorganic fertilizers; Residues @ 3 t ha-1 + Tricho-compost @3.75 t ha-1 + 75% less than recommended doses of inorganic fertilizers. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The highest grain yield was produced in T4 (Residues 3 t ha-1 +Trichocompost @1.5 t ha-1 + 25% less than recommended fertilizers treatment). From the above results it was found that the variety BRRI dhan29 and T4 (Residues 3 t ha-1 +Trichocompost @1.5 t ha-1 + 25% less than recommended fertilizers treatment) treatment exhibited the superior effect. The current study's findings indicate that the combination of manures and fertilizers increases yield and yield-contributing characteristics, and that Fimbristylis dichotoma residues have an herbicidal impact for inhibiting weed growth.

Influence of Nutrient Regulation on Ricebean (Vigna umbellata (Thunb.) Ohwi and Ohashi) Growth and Dry Matter

Aims: Within the realm of sustainable agriculture and its attendant issues, there exists a compelling need for a viable approach to cropping systems that integrates pragmatic and economically sound crop management tactics. This is imperative to uphold land productivity and secure a lasting provision of crops for human consumption. Acknowledging the pivotal contribution of organic manure when combined with chemical fertilizers in crop cultivation and the safeguarding of soil well-being, a research inquiry was formulated for a noteworthy cropping sequence.&#x0D; Study Design: Randomized block design.&#x0D; Place and Duration: School of Agricultural Sciences, Nagaland University, Medziphema. Duration: 2019-2021.&#x0D; Methodology: The study took place from 2019 to 2021 at the School of Agricultural Sciences (SAS), Medziphema Campus in Nagaland. The primary aim was to assess the lasting impact of both manure and fertilizers on yield and soil condition in a ricebean system over this two-year duration. In the second week of April in both 2019 and 2020, Dhaincha (Sesbania aculeata), a green manure crop, was sown using seeds. After a 30-day decomposition period, this green manure was incorporated into the soil. Soil samples were collected from the upper 0-15 cm layer of each experimental plot and analyzed. The experimental field was laid out in randomized block design with three level of organic manures i.e., poultry manure (PM), pig manure (PGM) and farm yard manure (FYM) along with doses of inorganic fertilizers : 100% RDF, 75% RDF, 50% RDF. The treatment combinations included T1 : GM (Sesbania) + PM (0.7 t ha-1) + 100 % RDF; T2: GM (Sesbania) +PM (0.7 t ha-1) + 75 % RDF; T3: GM (Sesbania) + PM (0.7 t ha-1) + 50 % RDF ; T4: GM (Sesbania) + PGM (0.7 t ha-1) + 100 % RDF; T5: GM (Sesbania) +PGM (0.7 t ha-1) + 75% RDF; T6: GM (Sesbania) + PGM (0.7 t ha-1) + 50 % RDF; T7: GM (Sesbania) +FYM (4 t ha-1) + 100 % RDF; T8: GM (Sesbania) + FYM (4 t ha-1) + 75 % RDF; T9: GM (Sesbania) +FYM (4 t ha-1) + 50 % RDF.&#x0D; Results: In treatment T1, which involved the application of a blend of green manure and poultry manure at a rate of 0.7 tons per hectare, coupled with a full dose of RDF, exhibited outstanding outcomes in ricebean cultivation. This resulted in elevated seed yields, improved seed quality, sustained soil health, and maximized economic gains for farmers in the foothill conditions of Nagaland.&#x0D; Conclusion: The substantial enhancement in ricebean growth parameters can be credited to the rich nutrient content and beneficial micronutrients present in poultry manure. combining Recommended Dose of Fertilizers (RDF) with poultry manure, known for its ability to boost nodule formation in legumes, improved soil fertility, fostered beneficial microbial activity, and promoted legume health, ultimately leading to higher yields. In contrast, farmyard manure (FYM) outperformed pig manure due to its balanced nutrients, microbial activity, organic matter, and positive impact on soil quality, creating an optimal environment for plant growth. Poultry manure's capacity to stimulate nodule formation, enhance soil fertility, and support legume health resulted in increased nitrogen fixation and improved yields in leguminous crops, fostering early root development and robust growth in ricebean crops.
