An experiment was conducted in the field, Department of Entomology, RVSKVV, College of Agriculture, Gwalior (M.P.) in Kharif- 2018 and 2019.Efficacy of biopesticides against jassid on okra. Experiment was laid out in Randomized Block Design with eight treatments. Biopesticides used in the experiments were Beauveria bassiana @ 0.5 kg/ha, Vertilicillium lecanii @ 1.0 kg/ha, Neem oil 5% @ 2.5 litre, Neem leaf extract 5% @ 25 kg/ha, NSKE 5% @ 25 kg/ha, Garlic clove extract 5% @ 25 kg/ha and Panchgavya 3% @15 litre/ha. All the biopesticides treatments were found significantly effective in reducing the population of jassid over control (untreated) plots. The biopesticides treatments, NSKE 5% were found most effective in reducing the jassid population followed by neem oil 5%, V. lecanii, neem leaf extract 5% and garlic clove extract 5%. Whereas, panchgavya 3% was found least effective in both the years. The highest fruit yield (119.56 q/ha) was recorded in NSKE 5% followed by B. bassiana and neem oil 5%. Whereas, minimum fruit yield was recorded in panchgavya 3% in both years. The highest net profit (27,128 Rs/ha) was obtained from the plots treated with B. bassiana followed by NSKE 5% (25,938 Rs/ha) and maximum benefit ratio in the B. bassiana (1:14.13) followed by V. lecanii (1:8.36), NSKE 5% (1:8:11) and garlic clove extract 5% (1:6.78).

Productivity improvement by adapting varieties to their environment was a major concern in the Sahel countries. Climatic constraints and low soil fertility are the main factors conditioning millet yield. The objective of this study is to evaluate the influence of edaphic parameters, sowing technics, and fertilization on the improvement of eight genotypes of millet. For this, a trial including eight varieties of millet in split plot was installed on the experimental station of CERRA in Maradi in 2020 during the rainy season. Soil samples at a depth of 20 cm were collected at the beginning and the end of experiment. Soil pH, organic carbon, and assimilable phosphorus were determined. Two sowing technics, seed balls, and direct sowing were applied. In seed balls, two types of fertilizer were used: the NPK (15-15-15) and ash. Phenology parameters and grain yield of each variety was measured. A statistical analysis of these data showed that edaphic parameters do not significantly influence yield. However, a significant variation in grain yield was observed among genotypes. Specifically, the variety ICMV IS 89305 exhibited a significantly higher grain yield (789 +/- 590 kg ha-1) compared to ICVH 18 (348+/-289 kg ha-1). Moreover, the different types of treatments applied to the seedlings showed a significant difference in terms of grain yield. The SSB treatments yielded more (1101+/-541 kg ha-1) than the BSC (480+/-463 kg ha-1) and BSE (317+/-322 kg ha-1) ball treatments. These results highlight substantial variability both within and between treatments. The positive effect of seed balls and fertilizer included vary according to the context. Specifically, when rainfall is scarce, seed balls prove to be non-efficient in improving the yield of millet.

The cultivation of Capsicum, commonly known as sweet pepper, is a critical component of global agriculture. As the demand for high-quality peppers continues to rise, there is a growing need to explore innovative cultivation practices that enhance yield and resource efficiency. Extensive experimental work was conducted at the research farm of Soil and Water Engineering, Punjab Agricultural University, Ludhiana from October 2008 to June 2009. This manuscript delves into the intricate interplay between low tunnel heights and irrigation regimes, seeking to unravel their collective impact on the growth parameters of capsicum. From the experiments, the data clearly revealed that plant height, leaf area index and dry matter accumulation was highest in 75 cm tunnel height followed by 90 cm and 60 cm tunnel height treatments throughout the crop season. Among all the irrigation treatments drip irrigation with 0.90 IW/CPE ratio gave the highest plant height and leaf area index than other irrigation treatments. Whereas drip irrigation with 0.75 IW/CPE ratio gave the highest dry matter accumulation than the other irrigation treatments.

Fenugreek is an annual legume crop with small seeds and self-pollinated plant, belonging to the family Fabaceae. It ranks as the third largest seed spice in India following coriander and cumin. The crop suffers from several diseases, among them wilt caused by Fusarium oxysporum is one of the major economically important diseases in many fenugreek growing states of India including Rajasthan. The survey for fenugreek wilt disease during Rabi (winter) season 2021-22 and 2022-23 revealed that wilt disease caused by Fusarium oxysporum is an imperative pathological problem. Average per cent disease incidence was 24.03 per cent recorded in surveyed districts of Rajasthan. Highest average disease incidence (29.31%) was reported in Nagaur followed by Sikar (24.85%), while lowest in Bikaner (17.93%) district.

Desmodium adscendens (Sw.) is a plant of the Fabaceae Family, a wild medicinal plant frequently found in industrial plantations, where it is exposed to pesticide residues. This makes species unsuitable for use as a raw material in pharmaceutical industry. To this end, domestication is one of best ways of cleaning up the species. During this process, the evaluation of a few physiological and biochemical compounds would be an indicator for the choice of planting material and the ecology species. Two types of plant material (seeds and stem) grown under three types of shade (accentuated, moderate, no shade) were tested. The leaves of various 90-day-old plants were used to determine physiological and biochemical parameters various. Results showed that chlorophyll a, carotenoids, polyphenols, total sugars, protein, proline and the activities of tyrosine ammonia-lyase, polyphenol oxidase and catalase were higher in leaves with moderate and no shading. However, under heavy shading, chlorophyll b content, phenylalanine ammonia lyase (PAL) and peroxidase enzyme activities were higher. Whatever shading type, the chl (a) content remained lower than that of chl (b). Also, total sugars, proline, ascorbate peroxidase and catalase were more abundant in the leaves of plants grown from stem. In contrast, phenolics, proteins and PPO are more abundant in leaves of seedlings.
Desmodium adscendens（Sw.）是一种豆科植物，是一种野生药用植物，经常出现在工业种植园中，并暴露于农药残留中。这使得该物种不适合用作制药业的原料。为此，驯化是净化该物种的最佳方法之一。在这一过程中，对一些生理和生化化合物的评估将成为选择种植材料和生态物种的指标。我们测试了在三种遮荫条件下（强遮荫、适度遮荫和无遮荫）生长的两种植物材料（种子和茎）。利用各种 90 天植株的叶片测定各种生理和生化参数。结果表明，中度遮阴和无遮阴叶片的叶绿素 a、类胡萝卜素、多酚、总糖、蛋白质、脯氨酸以及酪氨酸氨化酶、多酚氧化酶和过氧化氢酶的活性都较高。然而，在重度遮光条件下，叶绿素 b 含量、苯丙氨酸氨裂解酶（PAL）和过氧化物酶活性较高。无论采用哪种遮光方式，叶绿素（a）含量仍然低于叶绿素（b）含量。此外，茎叶中的总糖、脯氨酸、抗坏血酸过氧化物酶和过氧化氢酶含量更高。相比之下，幼苗叶片中的酚类、蛋白质和 PPO 含量更高。

A study was conducted during the kharif season of 2022 at the Research plot, Department of Agronomy, AKS University, Madhya Pradesh to investigate the impact of graded doses of fertilizers viz., Control (F0), NPK @ 18:18:18 kg ha-1 (F1), NPK @ 19:19:19 kg ha-1 (F2), and NPK @ 20:20:20 kg ha-1 (F3) and three varieties i.e., IPU-2-43 (V1), PU-31 (V2), Indira-1 (V3) on black gram. The experimental design employed was a Randomized Complete Block Design, with the 12 treatment combinations replicated three times. Results revealed that treatment F3 (NPK @ 20:20:20 kg ha-1) significantly enhanced plant height (40.73 cm), number of branches per plant (4.49), number of leaves per plant (27.09) and number of root nodules (30.89). This grade also resulted in maximum yield attributes such as the number of pods per plant (22.00), grains per pod (4.89), test weight (36.98 g), grain (9.31 q/ha) and stover yield (18.10 q/ha). Additionally, the highest protein content (21.71 %) in black gram grain was observed with the application of F3 (NPK @ 20:20:20 kg ha-1). Regarding varieties, Indira-1 displayed superior growth parameters and yield-contributing characters compared to IPU-2-43 and PU-31. Notably, Indira-1 exhibited higher protein content in seeds. The results suggest that the application of NPK @ 20:20:20 kg ha-1 and cultivation of the Indira-1 variety hold promise for enhancing black gram productivity.

This case study investigates the impact of different bio-stimulants, including Novel prime organic liquid nutrient, Vermi wash, and Cow urine, on vegetative growth, flowering, and fruit yield of sweet sensation variety of strawberry plants. An intensive research work was carried out at an experimental land located in north Konkan zone of Maharashtra, India. The experiment employs a Completely Randomized Design (CRD) with three replications to evaluate growth at various stages and yield parameters. The results demonstrate that the strategic application of 2% concentration of Novel prime organic liquid nutrient and 2% Vermiwash significantly improves the plant growth and yield of strawberry. This treatment remarkable yielded 5418 kg/ha, while the appreciable yield achieved to 4733 kg/ha for the Vermiwash treatment. The results also highlight the potential of sustainable strawberry cultivation and suggesting its viability for countries that traditionally depend on rain-fed crops. This may significantly improve the pattern of agricultural practices in those regions. Strawberry cultivation is an economically significant horticultural practice worldwide. Enhancing the growth, quality, and yield of strawberry plants is crucial for improving production and profitability.

This study assessed the yield gaps of chickpea (Cicer arietinum L.) in Mandi district of Himachal Pradesh where a total of 240 trials on improved chickpea cultivars viz. GNG 1581, GPF 2 and Himachal Chana 2 along with best practices were conducted by KVK in Mandi for three consecutive years under the Cluster Front Line Demonstration (CFLDs) program during Rabi 2015-16 to Rabi 2017-18. The study revealed that the demonstration yield of chickpea cultivars viz. GNG 1581, GPF 2 and Himachal Chana 2 were significantly better than the farmer's practice. Overall, a seed yield of 616 kg ha-1 was achieved in the three years of data collected in the demonstration plot, which was 40.32 percent higher than the farmer's practice. The technology and extension gap in the data collected under the three-year CFLDs program were 1546.5 kg ha–1 and 177 kg ha–1 respectively. The improved technology package not only improved water use efficiency, chickpea profitability in terms of gross and net returns, but also improved the benefit-cost ratio (BC). The overall technology index of 71.51 percent revealed a satisfactory performance of technology interventions, which can be further strengthened in the region by bridging the gaps through more effective research and extension services.

The study revealed that the demonstration yield of chickpea cultivars viz. GNG 1581, GPF 2 and Himachal Chana 2 were significantly better than the farmer's practice. Overall, a seed yield of 616 kg ha-1 was achieved in the three years of data collected in the demonstration plot, which was 40.32 percent higher than the farmer's practice. The technology and extension gap in the data collected under the three-year CFLDs program were 1546.5 kg ha–1 and 177 kg ha–1 respectively. The improved technology package not only improved water use efficiency, chickpea profitability in terms of gross and net returns, but also improved the benefit-cost ratio (BC). The overall technology index of 71.51 percent revealed a satisfactory performance of technology interventions, which can be further strengthened in the region by bridging the gaps through more effective research and extension services.","PeriodicalId":477440,"journal":{"name":"Journal of experimental agriculture international","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138964386","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}

Bananas (Musa acuminata L.) are confronted with a number of challenges imposed by bacterial diseases which lead to huge yield losses. In order to improve the yields of the banana plantation, one of the recommended management strategies which would be inexpensive and environmentally friendly was developed. The objective of this study was to improve the sanitary state of banana plant. To achieve this objective, bacteria associated with the different banana organs were isolated on Nutrient Agar (culture medium) and their morphological identification was carried out based on the cultural characteristics and the colour of the bacterial walls observed under an optical microscope and using reference documents (bacteriological identification keys). Antibacterial activity of Lantana camara and Euphorbia hirta extracts were evaluated in vitro on agar medium aginst Xanthomonas campestris pv. Pseudomonas solanacearum and Ralstonia solanacearum. The results showed that the banana plant harbours a diversity of bacteria species, the most frequent being Ralstonia solanacearum as it was isolated from all infected organs. The yields of the equeous extacts of Euphorbia hirta and Lantana camara were particularly high (7% and 13%) respectively, compared to those of the ethanolic extracts which were lower. Aqueous extracts of Euphorbia hirta, at 50 mg/ml, had bactericidal activity against Ralstonia solanacearum and Pseudomonas celebensis. Aqueous extracts of Lantana camara, at concentrations of 25 mg/ml and 50 mg/ml, exhibited bactericidal activity against P. celebensis. Meanwhile, the ethanolic extracts of L. camara, at 50 mg/ml had bacteriostatic activity against the development of P. celebensis. Ethanolic extracts of E. hirta had bactericidal activity on the growth of Xanthomonas campestris at 25 mg/ml and 50 mg/ml. The same activity was obtained with P. celebensis at 50 mg/ml. These results suggest that the aqueous and ethanol extracts of the tested plants at high concentrations could be used as alternatives to chemical products in the fight against banana diseases especially Xanthomonas, Pseudomonas and Ralstonia. Hence further studies need to be undertaken in order to isolate the active compounds from these extracts with bactericidal potential.

Landslides were frequently observed in nature that can result in significant property damage and fatalities. Land management in landslide-prone areas can be aided by preparing a landslide susceptibility map. The landslide susceptibility of Chaliyar river basin was evaluated using the logistic regression (LR) technique. For this, an inventory map of 592 prior landslides was created using Landsat 8 OLI satellite imagery. The inventory of landslides was then randomly split into 30% and 70% for model training and validation respectively. Fifteen landslide causative factors viz., Slope, Aspect, Curvature, Relative Relief, TWI, Distance to Road, Distance to Streams, Distance to Lineaments, Land Use Land Cover, Drainage Density, Road Density, Lineament Density, Geomorphology, Soil Texture, NDVI were considered for landslide susceptibility modelling. Utilising a Receiver Operating Characteristics Curve (ROC) and Area Under Curve (AUC) value, the resulting susceptibility maps were validated. Analysis reveals that the validation stage of the LR model had a ROC-AUC value of 0.815. The study also demonstrates that slope, soil texture and LULC play a substantial role on the occurrence of landslides in the study area. The proposed landslide susceptibility model is appropriate, taking into account the ROC-AUC (0.815), and can be applied to future land use planning and landslide mitigation in the Chaliyar basin.
