A field experiment was conducted at ARS, Bheemarayarnagudi, Karnataka to study the effect of phosphorus graded levels and inoculation of arbuscular mycorrhizal (AM) fungi under different establishment techniques in pigeonpea during kharif season of three years (2010-13) in Upper Krishna Project command area of Karnataka. The treatment consists of phosphorus graded levels (0, 12.5, 25, 37.5 and 50kg ha-1) with inoculation VAM fungi under two establishment techniques (Transplanted and dibbled) with randomized block design. Three-year pooled data indicated that, Application of 50 kg P + VAM under transplanting technique recorded significantly higher pigeonpea yield (1510 kg ha-1) and it was on par with application 37.5 kg P + VAM under transplanting method over rest of the treatment. The economics and nutrient uptake also noticed similar trend. It proved that pigeonpea could be successfully transplanted in the UKP command area of Karnataka by applying 37.5 kg of phosphorus ha-1 in conjunction with VAM fungus inoculation. This boosted crop productivity, nutrient availability, and net returns.

Tobacco caterpillar, Spodoptera litura (Fabricius) is an economically important polyphagous pest inflicting significant economic damage to numerous field and horticultural crops. Research was conducted at the Department of Entomology, Bihar Agricultural University, Sabour, Bhagalpur, Bihar, in laboratory settings to validate the presence of this pest. The investigation involved detailed measurements of the various larval stages, pupa, adult male, and female, of tobacco caterpillar including the wingspan. The first to sixth instars of S. litura exhibited significantly greater length and width as well as width of head capsule, when reared on the tomato as a host. The pupae of S. litura reached at their maximum length and width when raised on marigold (16.75 mm and 4.36 mm), while the minimum pupal measurements (14.10 mm and 4.42 mm) was observed in case of maize. In regards to the adult moths, both male and female specimens displayed the longest length and wing span when associated with tomato (16.71 mm and 18.22 mm for length, 38.47 mm and 38.73 mm for wingspan, respectively), whereas the smallest measurements were recorded for those associated with maize (14.35 mm and 16.95 mm for length, 35.10 mm and 35.12 mm wingspan respectively). The present study confirmed the presence of S. litura that require immense attention to prepare the management strategy against it.

Black gram is a type of legume that is widely cultivated and consumed in various parts of the world. It is believed to have originated in the Indian subcontinent and is one of the oldest cultivated legumes in the world. The field experiment was carried out to during kharif season of the year 2022 at departmental farm of Soil Science and Agricultural Chemistry, College of Agriculture, Latur. The experiment was laid out in randomized block design with three replications and eight treatments viz., T1 (RDF), T2 (RDF + Foliar application of humic acid @ 0.2 % at 20 & 35 DAS), T3 (RDF + soil application of humic acid @ 10 kg ha-1), T4 (RDF + soil application of humic acid @ 15 kg ha-1), T5 (RDF + soil application of humic acid @ 20 kg ha-1), T6 (T3 + foliar application of humic acid @ 0.2% at 20 & 35 DAS), T7 (T4 + foliar application of humic acid @ 0.2% at 20 & 35 DAS), T8 (T5 + foliar application of humic acid @ 0.2% at 20 & 35 DAS). The field study indicated that the nutrient uptake and content and grain and straw yield of black gram crop were significantly influenced due to soil and foliar application of humic acid and RDF. The uptake of N, P and K were recorded at harvest. Significant and maximum uptake of N, P and K were noticed with application of treatment T8 (RDF + soil application of humic acid @ 20 kg ha-1+ foliar application of humic acid @ 0.2% at 20 and 35 DAS), whereas the T1 (RDF) showed least values. grain and straw yield significantly affected due to T8 (RDF + soil application of humic acid @ 20 kg ha-1 + foliar application of humic acid @ 0.2% at 20 and 35 DAS) and the lowest grain and straw yield were recorded in T1 (RDF). Thus, it can be concluded that the soil and foliar application of humic acid increase the nutrient uptake and grain and straw yield. The significantly superior result recorded by treatment T8 (RDF + soil application of humic acid @ 20 kg ha-1 + foliar application of humic acid @ 0.2% at 20 and 35 DAS) next to this treatment T7 (RDF + soil application of humic acid @ 10 kg ha-1 + foliar application of humic acid @ 0.2% at 20 and 35 DAS) was best option. The significant increase in grain and straw yield of black gram was due to application of RDF with soil and foliar application of humic acid which mitigates scarcity, increased absorption effectively and increased photosynthetic activity which leads to higher grain and straw yield.
黑糯米是一种豆科植物,在世界各地广泛种植和食用。据说它起源于印度次大陆,是世界上最古老的栽培豆科植物之一。这项田间试验是在 2022 年的收获季节在拉图尔农学院土壤科学和农业化学系农场进行的。实验采用随机区组设计,有三个重复和八个处理,即:T1(RDF)、T2(RDF)、T3(RDF)、T4(RDF)和T5(RDF)、T1(RDF)、T2(RDF + 叶面喷施 0.2 % 腐植酸 @ 20 和 35 DAS)、T3(RDF + 土壤喷施腐植酸 @ 10 kg ha-1)、T4(RDF + 土壤喷施腐植酸 @ 15 kg ha-1)、T5(RDF + 土壤喷施腐植酸 @ 20 kg ha-1)、T6(T3 + 叶面喷施腐植酸 @ 0.2%)、T7(T4 + 叶面喷施腐植酸 @ 0.2%,20 和 35 DAS)、T8(T5 + 叶面喷施腐植酸 @ 0.2%,20 和 35 DAS)。田间研究表明,土壤和叶面喷施腐植酸及 RDF 对黑禾的养分吸收和含量、谷物和秸秆产量有显著影响。收获时记录了氮、磷和钾的吸收量。施用 T8 处理(RDF + 土壤施用腐植酸 @ 20 kg ha-1 + 在 20 DAS 和 35 DAS 叶面施用腐植酸 @ 0.2%)对氮、磷和钾的吸收显著且最大,而 T1(RDF)的吸收值最小。T8(RDF + 土壤施用腐植酸 @ 20 kg ha-1 + 在 20 DAS 和 35 DAS 叶面施用腐植酸 @ 0.2%)对谷物和秸秆产量有显著影响,而 T1(RDF)的谷物和秸秆产量最低。因此,可以得出结论:土壤和叶面喷施腐植酸可增加养分吸收,提高谷物和秸秆产量。处理 T8(RDF + 土壤施用腐植酸 @ 20 kg ha-1 + 在 20 DAS 和 35 DAS 叶面喷施腐植酸 @ 0.2%)的结果明显优于处理 T7(RDF + 土壤施用腐植酸 @ 10 kg ha-1 + 在 20 DAS 和 35 DAS 叶面喷施腐植酸 @ 0.2%)。黑粒禾谷粒和秸秆产量的显著增加是由于 RDF + 土壤施肥和叶面喷施腐植酸缓解了稀缺性,有效增加了吸收,提高了光合作用,从而提高了谷粒和秸秆产量。

A field experiment was conducted at College of Agriculture, V. C. Farm, Mandya during Kharif 2021-22 to evaluate the effect of lime application for neutralizing fertilizer acidity on growth and yield of maize in Alfisols. There were eight treatments that include 500 kg lime (T3) and 250 kg granular dolomite (T4) + FYM and recommended dose of fertilizers (RDF), 100% RDF and FYM + 100 and 50% fertilizer acidity neutralization with lime (T5 and T6) and granular dolomite (T7 and T8), absolute control (T1) and FYM + 100 % RDF (T2). The experiment was laid out in Randomized Complete Block Design with three replications. The results revealed that application of lime @ equivalent to 100% neutralization of fertilizer acidity with 100% RDF and FYM (T5) recorded significantly higher plant height (221.56 cm), number of leaves (13.01 plant-1), leaf area (6389 cm2 plant-1) and total dry matter accumulation plant-1 (168.74 g plant-1) which was on par with T8, T6, T7 and T4. Similarly, significantly higher yield parameters like cob length (21.98 cm), cob girth (20.01 cm), number of rows cob-1 (16.86), number of kernels row-1 (36.98) and test weight (35.98 g) were recorded in T5 when compared to T2, T3 and T1. Kernel and stover yield (81.57 and 90.67 q ha-1, respectively) was observed to be significantly higher in T5 treatment which was on par with T6 which clearly indicated that 100% neutralization of fertilizer acidity with lime along with 100% recommended dose of fertilizer and FYM is necessary for obtaining higher growth and yield of maize.

Soil fertility assessment and mapping bases, to increase fertilizer usage efficiency, decision-makers, planners, and soil management in undulating slopes farming of Ethiopian highlands like Bale Highland. The study aimed to assess and map soil fertility status along toposequence under different land use types at the Danka watershed of Dinsho District Bale Highland, Southeastern Ethiopia. Following the initial reconnaissance field survey, 54 composite soil samples were prepared from the three land use types (natural forest, grazing, and cultivated) at three slope positions lower (0 - 10%), middle (10 - 15%), and upper (15 - 30%) at a soil depth of 0 to 20 cm. Finally, the laboratory results were interpolated using the IDW interpolation technique in ArcGIS software 10.5 for the soil fertility status map and further analyzed using R software 4.1.1 Version for mean separation. The study findings indicate that the soil texture class of the study was loam to clay loam, clay loam, and clay to clay loam at the upper, middle, and lower slope positions, respectively. The finding revealed that the values varied from 5.81 – 6.66, 2.07 – 6.25%, 0.13 – 0.71%, 2.83 – 17.56 gm/kg, and 14.04 -38.80 cmol (+)/kg) for the soil pH, organic matter, total nitrogen, available phosphorus, and CEC, respectively. In this study, most of the soil fertility status of the Danka watershed was as follows: natural forest > grassland > cultivated land use types and lower slope > middle slope > upper slope positions. In conclusion, the main factors contributing to the area's declining soil fertility status were monocropping, total crop residue removal, soil erosion, nutrient leaching, and inadequate soil management. The results of the current study offer the basis for the work of farmers, planners, decision-makers, and other agriculture-related stakeholders. Integrated soil fertility management with biophysical soil conservation measures is advisable for cultivated land at all slope positions. Further, a study on slope position-based crop response fertilizer rating for agricultural precision and ensuring food security is recommended in undulating fields of the Danka watershed.

A field experiment was conducted at Agricultural Research Station, Kumta, Uttara Kannada district during the rabi-summer season of 2016-17 to investigate the Bio-efficacy of herbicides on weed density, weed control efficiency, productivity and groundnut quality in coastal zone of Karnataka under rice-groundnut system. The experiment followed a RBD with nine treatments out of which six treatments involved the pre-emergence application of herbicides followed by either hand weeding or early post-emergence application, along with control treatments. The results indicated that the pre-emergence application of pendimethalin 30% E.C. (1.5 kg ha-1), followed by one hand weeding at 25 days after sowing (DAS), resulted in significantly reduced total weed density and weed dry matter. This treatment also demonstrated higher weed control efficiency and lower weed index. Moreover, it led to increased pod yield, kernel yield and improved quality of groundnut compared to other treatments.

Soil health and appropriate nutrient management are critical components of sustainable agriculture, influencing crop yield, environmental sustainability, and overall food security. The ability of soil to function as a living ecosystem is referred to as soil health. supports plant and animal life while protecting the environment. It refers to how physical, chemical, and biological activity interact in the soil. Mineral matter, organic matter, water, and air are all critical components of soil health, and each contributes to plant growth. Soil health indicators include physical, chemical, and biological factors that help assess the soil's state. For optimal soil health, these indicators must be balanced. However, there are significant issues to address, such as decreased soil organic matter, declining soil fertility due to nutrient deficits, physical soil degradation, and chemical soil degradation caused by excessive chemical use. Practices for sustainable soil management are critical for addressing these concerns. Balanced fertilization, organic matter incorporation, crop rotation, cover cropping, reduced tillage, and precision nutrient delivery are examples of these. Mitigating issues such as nutrient pollution, soil erosion, and soil deterioration is critical to maintaining agriculture's long-term viability.

Mineral matter, organic matter, water, and air are all critical components of soil health, and each contributes to plant growth. Soil health indicators include physical, chemical, and biological factors that help assess the soil's state. For optimal soil health, these indicators must be balanced. \u0000However, there are significant issues to address, such as decreased soil organic matter, declining soil fertility due to nutrient deficits, physical soil degradation, and chemical soil degradation caused by excessive chemical use. Practices for sustainable soil management are critical for addressing these concerns. Balanced fertilization, organic matter incorporation, crop rotation, cover cropping, reduced tillage, and precision nutrient delivery are examples of these. Mitigating issues such as nutrient pollution, soil erosion, and soil deterioration is critical to maintaining agriculture's long-term viability.","PeriodicalId":507605,"journal":{"name":"International Journal of Plant & Soil Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140712686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantify and understand soil nutrient loss under different undulating topography farming bases for site-specific management and targeted fertilizer application rates. The study aimed to assess the effect of slope positions on soil physicochemical properties at the Danka watershed of Dinsho District Bale Highland, Southeastern Ethiopia. Consequent to the reconnaissance survey, soil samples were taken from the cultivated land use type in three replications at three different soil depths (0-0, 20-40, and 40-60 cm) and three slope positions (upper, middle, and lower), analyzed follow standard laboratory procedure and further analyzed using R software 4.1.1 version. The results showed soil physicochemical properties were significantly (P ≤ 0.05) influenced by the interaction between slope positions and soil depth. The results of soil physical properties varied from 1.29 -1.73 g cm-3, 2.47 – 2.74 g cm-3, 47.80 - 36.75%, 10.78 – 15.11%, 12.76 – 18.16%, and 4.06 – 8.16% bulk density, particle density, total porosity, FC, PWP, and AWHC, respectively. Selected soil chemical properties varied from 5.91 - 6.45, 0.64 - 3.20%, 0.04 - 0.25%, 1.14 - 5.60 gm/kg, and 10.24 - 37.24 cmol (+)/kg) soil pH, organic matter, total nitrogen, available phosphorus, and CEC, respectively. The values of exchangeable bases were concentration increased from the upper slope position toward the lower slope position and with increased soil depth. Soil micronutrients were increased with increased slope and decreased with increased soil depth. The lowest slope position had relatively better soil nutrient contents than other slope positions. It is advised that integrated soil fertility management, biophysical soil and water conservation, and slope-based, site-specific fertilizer rating for advance agricultural precision and ensure food security.

The intentional integration of trees into an agroecosystem results in agroforestry practices such as windbreak, which simultaneously help the economy, the environment, and society. It is a crucial tool for safeguarding agricultural land and boosting crop productivity. An investigation was therefore conducted to determine the impact of windbreaks (Casuarina equisetifolia L.) on paddy productivity in South Gujarat. In the current study, we found that environmental competition caused paddy growth and production to decrease close to the Casuarina windbreak. The impact of the windbreaks on paddy growth and yield became positive, and the continuously increased distance from the windbreaks reached its maximum at 17 m (Plant height 97.34 cm, number of tillers per plant 11.17, total fresh weight plant 17,799 kg ha-1, dry straw weight 6,577 kg ha-1 and grain yield 4,103 kg ha-1) and then gradually decreased (plant height 83 cm, tillers per plant 8.17, total fresh weight plant 12,315 kg ha-1, dry straw weight 4,855 kg ha-1 and grain yield 3,101 kg ha-1). The wind velocity maximum (4.57 km hr-1) close to windbreaks exhibits an opposite tendency, decreasing continually to a minimum (3.32 km hr-1) at a distance of 17 meters from the windbreaks before increasing once again. In addition, this system's net returns (Rs. 40,619) and benefit-cost ratio (0.61) were noticeably higher than those of open fields (Rs. 34,749 and benefit cost ration 0.52). In contrast to the control, the pH of the soil beneath the windbreak was reported to be considerably closer to neutral (7.46), while electrical conductivity (0.19 dS/m) was reduced. The impact of windbreaks was found to considerably increase soil organic carbon (0.68%), accessible nitrogen (234.46 kg/ha), phosphorus (75.75 kg/ha), and potassium (398.07 kg/ha) as compared to control. According to the study's overall findings, windbreak-protected paddy fields perform noticeably better than open ones.
