Identification and Discrimination of Citrus Orchards using Satellite Imagery over Sirsa District of Haryana
In the recent era mapping of particular crop becomes an interdisciplinary nature in which agricultural and geo-informatics sectors comes together and monitoring the particular crop. In order to analyze the potential of remote sensing based technology for the mapping of crops in horticulture field, the present study was initiated for the discrimination and classification of citrus orchards with the help of multi-temporal satellite data. To achieve the objectives of the study Multi-date Sentinel-2 images covering the study area were acquired. The major challenge was to discriminate the Citrus plantation from agriculture and other plantation cover. After analyzing the multi-temporal data the optimum dates depicting the clear differentiation between the citrus plantation and associated other agricultural and horticultural crops were selected. The NDVI of the selected optimum multi-date data was layer stacked. The supervised classification based approach wa performed with the help of ground truth points for the identification and discrimination of Citrus orchards. This study provides the potential of using high-resolution NDVI imagery of Sentinel-2 for the identification, discrimination and demarcation of citrus orchards.
A comprehensive review of the biochar-mediated enhancement of soil acidity, crop performance and soil properties
Biochar, a carbon-rich material derived from biomass pyrolysis, has gained considerable attention as a soil amendment for improving soil fertility and crop productivity. One of the key benefits of biochar is its ability to mediate soil acidity, influencing soil pH and buffering capacity. Biochar can act as a liming agent, raising soil pH in acidic soils, or as an acidifying agent, lowering pH in alkaline soils, through its alkaline or acidic functional groups, respectively. This property makes biochar a versatile tool for managing soil acidity in different agricultural systems. The application of biochar to acidic soils can enhance crop performance by improving nutrient availability, reducing toxic metal concentrations, and promoting microbial activity. Biochar can also increase the cation exchange capacity (CEC) of soils, leading to improved nutrient retention and reduced leaching losses. Furthermore, biochar-mediated enhancement of soil pH can promote the dissolution of minerals and the release of essential plant nutrients, such as phosphorus, calcium, and magnesium, which are often limited in acidic soils. Apart from influencing soil acidity and crop performance, biochar can also improve other soil properties. Biochar can enhance soil water holding capacity, reduce soil erosion, and increase aggregate stability, thereby improving soil structure and fertility. Biochar can also sequester carbon in the soil, contributing to climate change mitigation by reducing greenhouse gas emissions. In this review, we summarize the current state of knowledge on the effects of biochar on soil acidity, crop performance, and soil properties. Overall, biochar-mediated enhancement of soil acidity can have profound positive effects on crop performance and soil properties, making it a promising soil amendment for sustainable agriculture.
Defense Response in Brinjal plants treated with Oil-cakes against Root-knot nematode, Meloidogyne javanica
Brinjal (Solanum melongena) belongs to the family Solanaceae, it is an important vegetable crop and grown all around the world. It is one of the most important hosts for plant parasitic nematodes, mainly root-knot nematode, Meloidogyne javanica. Experiments were conducted to test the efficacy of oil-cakes (viz., castor, mahua, karanj, mustard and neem cake) against root-knot nematode in laboratory condition (per cent hatching and per cent mortality after 24, 48 and 72 hours) through different concentration (0.5, 1, 2, 5 and 10 per cent), management of root- knot nematode in brinjal (@ 10 per cent) in pot and field condition and tested the effect of oil-cakes on estimation of PPO, PAL and Phenol in brinjal roots. Results showed that all the tested oil-cakes significantly reduced the per cent hatched juveniles and increased the per cent mortality of juveniles, increased the brinjal plant growth parameter as well as reduced nematode reproduction and increased the level of PPO, PAL, and phenol in brinjal roots as compared to untreated check. Among the tested oil-cakes neem cake was found most effective treatment with minimum per cent hatched juveniles and maximum per cent mortality of juveniles @ 10 per cent concentration after 72 hrs. Similarly, neem cake @ 10 per cent concentration was found superior to improving plant growth parameters, reducing nematode population and to enhance PPO, PAL, and phenol activity.
Performance of winter pulses under residual soil fertility with different crop establishment techniques in rice fallow in Meghalaya
A field experiment conducted in rice fallow to identify suitable winter pulses under residual soil fertility with different crop establishment techniques. The experiment was conducted in a split plot design with two nutrient management in kharif rice (organic (FYM equivalent to the recommended dose of nitrogen of 80 kg/ha) and integrated nutrient management (50% organic and 50% chemical fertilizer)) with a combination of three crop establishment techniques in winter pulses (utera, flat bed line sowing, and raised bed sowing), and four winter pulses (lathyrus, chickpea, lentil and field pea) in sub plot with three replications. Results showed that lathyrus, field pea and lentil could be the potential winter pulses to utilise residual nutrients in low land rice fallow Meghalaya. Raised bed and utera sowing are suitable crop establishment techniques in Meghalaya's high rainfall region. Productivity of all the winter pulses was higher in raised beds, which was primarily attributed to higher dry matter, branch/plant, and yield attributes such as grain weight/plant, which ultimately led to higher grains as well as straw yield. Hence, lathyrus, field pea and lentil could be included in rice fallows, ideally with raised beds and utera for higher yield in Meghalaya.
In vitro studies in Gymnema sylvestre (Gudmar)-A high value medicinal plant
Gymnema sylvestre R.Br. (syn. Periploca sylvestris Retz), sometimes referred to as Gudmar, is a main medicinal plant utilised under various medical systems as a treatment for the curing of diabetes mellitus. The culture of selected explants namely shoot apex, nodal stem, leaf and inflorescence on five selected media having MS basal salts supplement with several concentrations of cytokinins (KIN and BAP) plant growth regulators, effected on the establishment of aseptic culture, swelling of explants, disorganized proliferation of cells from the cultured explants and shoot bud growth from the shoot apex and nodal stem explants. The best establishment of aseptic culture was observed on medium M5 (MS + 1.5 “mgl-1” BAP + 0.5 “mgl-1” KIN). The highest swelling of the cultured explants was observed on medium M4 (MS + 2.0 “mgl-1” BAP + 1.0 “mgl-1” KIN). The best caulogenesis was observed on medium M3 (MS + 2.0 “mgl-1” BAP + 0.5 “mgl-1” KIN). Cultured explants leaf were the best for establishment of cultures, swelling and caulogenesis induction. The development of existing shoot bud was the maximum in medium M5 and shoot apex showed better shoot growth compared to nodal stem. The developed shoots can be used as source of new explants and their culture will result in propagule multiplication. Finally, the in vitro developed shoots can be rooted leading to the establishment of micropropagation method in this important remedial plant.
