As variability is crucial for crop improvement, it is better to characterise several genotypes that are derived from either seedlings or wild types. This research facilitates the identification of cultivars, genotypes and the elimination of identical plants within populations. The study was conducted in year 2022-23 with thirty-three guava genotypes of Jabalpur district to examine various morphological characteristics such as tree height, trunk girth and canopy diameter, branching attitude, stem colour in young shoots, branching density, mature leaf colour, leaf shape, leaf base shape, leaf tip shape, leaf curvature and leaf twisting. The experimental investigation was carried out at the Fruit Research Station, Imaliya, under the Department of Horticulture at the College of Agriculture, Jabalpur, Madhya Pradesh. Genotypes exhibited notable diversity in their morphological traits with respect to height, gith, canopy and several leaf-based characteristics. For the estimation of diversity, the DUS guideline of UPOV was followed. All the genotypes in this study aged between eight to thirteen years. Descriptive statistics showed that, the height of the trees varied between 2.78m (JG-322) and 6.12m (JG-325). The trunk girth ranged between 27.21cm (JG-314) to 87.23cm (JG-319). The canopy in the east-west direction ranged from 4m (JG-325) to 8.34m (JG-322) whereas, in north-south direction varied 3.68m (JG-325) to 8.41m (JG-322). The observed diversity in these traits yielded significant insights that might drive the selection of parental plants for an advanced guava breeding initiative.
A study was conducted to assess the flowering behaviour of 33 guava genotypes of Jabalpur district of MP. Under this study, various guava genotypes were evaluated for their flowering characteristics over two consecutive years. Genotype JG-309 consistently exhibited the earliest flowering, while late flowering was observed in genotypes JG-311 and JG-330. The timing of full bloom varied among genotypes as influenced by both genetic factors and environmental conditions. Significant diversity was observed in the number of floral buds (11.66 to 16) and open flowers per shoot (11.33 to 13.16) across genotypes, reflecting variations in reproductive capacity. Understanding these variations is crucial for effective orchard management, including pruning, fertilization and pest control. Moreover, the duration of flowering (23 to 48 days) varied widely among genotypes, with implications for harvest timing and fruit quality. Genotypes were categorized into short, medium and long flowering duration groups, highlighting the influence of varietal characteristics and local climate on flowering dynamics. These findings contribute to our understanding of guava flowering patterns and provide insights for optimizing cultivation practices to enhance yield and fruit quality.
A field experiment was carried out during the rabi season in the Experimental Field, Department of Soil Science and Agricultural Chemistry, JNKVV, Jabalpur (M.P.) under RBD design with four replications consisting of five treatments of two types of biofertilizers: Pseudomonas and Biofertisol, and scheduled combinations of inorganic fertilizers based on STCR (Soil Test Crop Response) to achieve the desired yield using the vegetable pea variety PSM-3. The response due to treatment of T4 (TY 100 q (58:110:47) + 5 t FYM+1 spray of Pseudomonas+1 spray of Biofertisol) was significantly effective in increasing nodulation attributes (nodulation enumeration, biomass and leghaemoglobin content) by 28.46, 47.15, and 35.29%; 78.33, 95.86, and 86.17%; and 21.70, 65.70, and 20.26%, respectively, relative to that of control. Yields of the crop were best harvested due to T4 by 85.97 % over that of control 56.70 kg ha-1. The continuous application of chemical fertilisers has decreased the fertility of the soil and degraded the soil. The reduction in the fertility of the soil has resulted in poor crop yields. The nutrient management of all the treatments involves the judicious use of organic and inorganic fertilizers, along with microbes, to meet the nutrient needs of the crop while minimizing environmental impacts.
This research was conducted at the Forestry Research Farm of Jawaharlal Nehru Krishi Vishwa Vidyalaya in Jabalpur, Madhya Pradesh, during the consecutive Rabi seasons of 2021-22. The study employed a double split plot design with three factors: land use systems (S1- open system and S2- agroforestry system), sowing dates (D1- 12 Nov, D2- 27 Nov, D3- 12 Dec), and wheat varieties (V1 - MP-3336 and V2 - GW-322). Each experimental treatment was meticulously replicated three times to ensure robust statistical analysis. Estimating nitrogen and protein content in wheat is crucial for nutrition, quality control, pricing and crop management. Therefore the objective of the study was to estimate nitrogen and protein content in grains of wheat under open and Pongamia Pinnata based agroforestry system. Nitrogen content in wheat grains was quantified using Modified Kjeldahl Method, and subsequently, protein content was calculated based on the determined nitrogen levels. The outcomes of this investigation consistently revealed that the open system consistently exhibited higher levels of nitrogen and protein content when compared to the agroforestry system. Furthermore, earlier sowing dates, particularly D1, contributed to increased nitrogen and protein content, although statistical significance was not achieved. Substantial varietal differences were observed, with MP-3336 consistently outperforming GW-322 in terms of nitrogen and protein content. These findings emphasize the critical role of land use strategies, sowing timing and wheat variety selection in augmenting the nitrogen and protein content of wheat crops, thereby making significant contributions to sustainable agricultural practices and enhancing food quality in regions reliant on wheat production.
The field experiment was conducted during the Rabi season of 2018-19 at the Agricultural Research Farm of Rajiv Gandhi South Campus, Banaras Hindu University, Barkachha, Mirzapur, Uttar Pradesh, India. This study aimed to investigate the effects of varying levels of phosphorus and inoculation with Phosphate Solubilizing Bacteria (PSB) on nutrient content and uptake in chickpea (Cicer arietinum L.) in a custard apple-based agri-horticultural system. The experimental design employed a Factorial Randomized Block Design with three replications and twelve treatments, resulting in a total of 36 plots. The treatments ranged from different levels of phosphorus and PSB inoculation, denoted as T1 to T12. The study assessed the impact of these treatments on nitrogen (N), phosphorus (P) and potassium (K) content in grain and straw, as well as their uptake by chickpea. Findings reveal that higher PSB levels and phosphorus applications led to increased nitrogen and phosphorus content and uptake in both grain and straw, demonstrating a significant synergistic effect. Conversely, potassium content and uptake exhibited limited response to PSB inoculation. Moreover, protein content and yield in grain and straw significantly improved with these treatments.
The current study was carried out on wedge grafting in Mango (Mangifera indica L.) cv. Dashehari during the2022-23 at the Fruit Research Station, Imaliya, Department of Horticulture, JNKVV Jabalpur. This research includes the use of many different plant growth regulators, ZnSo4, and growing conditions. The research was carried out using a statistical design known as Factorial Completely Randomized Design (FCRD).The primary objective of this study is to determine the influence that different scion dip treatments and growing conditions have on the physiological characteristics of the plant. According to the findings, among the various treatments, IAA 200 ppm + ZnSo4 500 ppm under shade net condition was proved superior with respect to maximum chlorophyll content index (27,18.5), leaf area duration (2720.67 cm2/day, 2,620.67 cm2/day), leaf area index (8.65,1035) and light transmission ratio (24.05,18.15) at 60 and 120 days after grafting (DAG). It was also noticed that scion dip treatments with IAA 200 ppm in combination with ZnSo4 500 ppm under the shade net condition were favorable as compared to the open condition.

It discusses how remote sensing systems, with their multispectral and multi-temporal capabilities, support various horticultural applications such as crop yield estimation, abiotic and biotic stress management, crop classification, canopy measurement, crop area estimation, and even crop insurance validation. The use of Geographic Information Systems (GIS) and the Global Positioning System (GPS) in tandem with remote sensing is explored in the context of spatial analysis, mapping, and precise navigation.
A field experiment was conducted during the rabi season in the Experimental field, Department of Soil Science, JNKVV, Jabalpur (M.P.) under RBD design with four replications comprising five treatments of two types of biofertilizers: Pseudomonas and Biofertisol and scheduled combinations of inorganic fertilizers based on STCR (Soil Test Crop Response) for achieving targeted yield by using variety of vegetable pea, PSM-3. The best response was recorded from the application of treatment T5 (TY120 q(87:147:74) +5tFYM) for increasing the content of soil available nutrients (N, P and K) by 7.89, 29.95 and 8.25%, respectively over that from control. Effect due to T4 was significantly prominent on the proliferation of microorganisms viz., Rhizobium sp., Pseudomonas sp., and Lactobacillus sp. better by 6.79 log cfu (61.38 x 105 cfu g-1 soil), 6.44 log cfu (27.67 x 105 cfu g-1 soil) and 4.42 log cfu (26.18 x 103 cfu g-1 soil), respectively over control. The same treatment T4 induced the enzyme activity of dehydrogenase by 86.99% as compared to that of the control (5.23 µg TPF hr-1 g-1). Yields of the crop were best harvested due to T4 by 81.91% over that of control 56.93 kg ha-1. The vegetable pea (Pisum sativum L.), a cool-season crop and an important pulse crop in India. One of the impediments to supporting vegetable pea production and productivity is low soil fertility. Anthropogenic causes such as heavy use of fertilizer exacerbated the problem. A combination of fertilizers, biofertilizers and FYM are the solution to the problem since it makes use of available organic and inorganic nutrients and microbes to create an environmentally sound and economically sustainable farming system.
A field experiment was conducted in 2020–21 at the Fruit Research Station, Imaliya, Department of Horticulture, JNKVV, Jabalpur. The AFRBD (Asymmetrical Factorial Randomized Block Design) was set up with 20 distinct treatment combinations of soil media Soil + Sand, Soil + Vermicompost, Soil + Sand + Vermicompost, Soil +Vermicompost + Biofertisol, Soil + Vermicompost + Azatobactor + PSB + KSB and plant growth regulator i.e. GA3 0 ppm (control), GA3 100 ppm, GA3 200 ppm, GA3 300 ppm. The vigour and germination of seeds were significantly impacted by the type of media used and the usage of plant growth regulators. In regard to the growth parameter, better values for seedling height, number of leaves and stem girth at 30, 60 and 90 days after sowing were found with treatment GA3 200 ppm. Growth metrics, such as root length, fresh shoot weight, dry shoot weight and dry root weight at 120 days, revealed improved results with a higher vigour index when the combination of GA3 200 ppm + growing medium (soil+ vermicompost+ Biofertisol) were applied. The GA3 200 ppm with growing medium (Soil+ Vermicompost+ Biofertisol) were proven to be better in terms of the seed germination parameters. Minimum time was taken for seed germination and increased seed germination percentage had been recorded at 30 days after planting.
A study was conducted during the season of 2022-23 at the fruit research station in Imalia, which is affiliated with the Department of Horticulture at the JNKVV in Jabalpur. The objective of the study was to evaluate the positive effect of foliar sprays containing NAA, Urea, Nano-urea, and Biofertisol on the fruit quality of mango (Mangifera indica L.) cv. Langra. The experiment was laid out in Randomized Block design in three replications and all the treatments were replicated thrice by using the single tree as a unit. Each treatment was carried out with one tree for each replication. At the full bloom and pea stage, the spraying of three different concentrations of NAA (20 ppm, 30 ppm, and 40 ppm), Urea (2%, 3%, and 4%), Nano-urea (0.2%, 0.3%, and 0.4%) and Biofertisol (5 ml/l, 10 ml/l, and 15 ml/l) was compared with the control, which consisted of no spraying. According to the findings of the experiment, applying a foliar spray containing 40 ppm of NAA resulted in a significant improvement in the quality parameter, as measured by a maximum TSS value of 22.22 oBrix, a maximum TSS: acid ratio of 117.13, maximum ascorbic acid content of 26.70 mg/100g, a minimum acidity content of 0.19%, and reducing sugars of 6.74% and total sugars of 17. During the evaluation, it performed at the same level as T3 (NAA 30 ppm), T2 (NAA 20 ppm), and T7 (Urea 4%).
