Starry Night Panorama with Advanced Feature Extraction and Star Stitching
Panoramic photography involves merging multiple photos of the same scene, each with overlapping views, to create a detailed image. When combining astrophotography with panoramic landscapes, challenges arise from image noise and subject motion. To address this, incorporating spatially variant registration steps in the panorama process can merge several shorter exposures into a final image with reduced noise and without motion artifacts. This method tackles two main issues in creating night sky panoramas: low signal-to-noise ratio (SNR) and motion blur.Initially, the images are divided into land and sky segments. Then, potential star locations are identified from a star image. Extracting features from night images is complex, and the Scale-Invariant Feature Transform (SIFT) algorithm is chosen for its robustness to rotation, scale changes, and noise. In astrophotography panoramas, more features need extraction, and SIFT performs well compared to other methods.Next, matching star features between images with common points allows combining two short exposures. A seamless blending technique removes visible seams between merged images. Compensating for star motion involves warping images using local transformations for smooth alignment. Finally, the combined exposures are stitched into a panorama using a spherical projection method

Not AvailableAn entomopathogenic fungus belonging to the genus Hirsutella was found infecting the mango
hopper, Idioscopus clypealis (Lethierry) (Hemiptera: Cicadellidae), for the first time in India in September
2011. The report of a natural control agent of mango hopper during the off season has special significance
because its outbreak depends upon its residual hibernating population.Not Availabl

Not AvailableFruit flies (Diptera: Tephritidae) are one of the most diverse group of insects, comprising over 4000 species in 481 genera. This study involved four mango growing districts of Jharkhand situated between 22º48' to 23º45' N L and 84º21' to 85º30' E L. Methyl eugenol based parapheromone traps were used for detection and monitoring of fruit flies pests during fruiting period (from March to July) of mango in year 2012. Three fruit flies species, Bactrocera zonata (Saunders), Bactrocera dorsalis (Hendel) and Bactrocera diversa (Coquillett) were recorded during the monitoring period. According to data of observation on this investigation, B. Zonata was recognised as the predominant species infesting mango fruits in the state, comprising 95.04, 93.12, 94.65 and 96.76 percent of population in mango growing areas of Ranchi, Gumla, Lohardaga and Khunti, respectively.
Besides this, low population of B. dorsalis (2.13 to 4.01 percent) and B. diversa (0.60 to 1.50 percent) from different areas were also recorded. Maximum population index (FTD) were 536, 443, 715 and 460 recorded from Ranchi, Gumla, Lohardaga and Khunti district, respectively in the month of April, 2012 coincided with most susceptible stages of infestation viz. stone to fully grown fruit of mango.Not Availabl

Not AvailableCoccinellids are the major natural enemies of many sucking pest in agro-ecosystems. A total of 2301 specimens of predaceous coccinellids were collected and identified to 16 species, of which 7 were recorded for the first time from Jharkhand, belonging to two sub families of family coccinllidae. Anegleis cardoni,
Cheilomenes sexmaculata and Illeis indica were found most frequent and abundant. When species diversity was compared among different locations and it was found that Shannon- Wiener diversity index varied from 2.126 to 1.376 indicated that species were less diverse but were frequently present. Peak population of coccinellids in mango orchards of region was recorded in the month of February and March. Thus, these results are discussed with current thinking of coccinellids as an important part of integrated pest management in mango orchards of region.Not Availabl

Not AvailableA trial was conducted during 2014–15 to 2017–18 to develop a bael (Aegle marmelos Correa) based production system for the eastern plateau and hill region of India with the approach of enriching the plant basin through mulching or soil incorporation of biomass obtained from different biomass yielding plants viz. Tephrosia (Tephrosia candida), Subabul (Leucaena leucocephala), rice bean (Vigna sesquipedalis), vegetable soybean (Glycine max) and weeds growing in the alley area. The experiment consisted of 11 treatments laid out in Randomized Block Design. The maximum dry biomass yield (5.70 to 12.80 t ha-1) and recycling of nutrients (cumulative of 4 years) into the basin of bael plants (1031.94, 56.16 and 372.06 kg ha-1 N, P and K, respectively), as well as plant vigour of bael were recorded with Tephrosia treatments. All the treatments except mulching of vegetable soybean resulted in a significant increase in soil organic carbon in the plant basin. Significantly higher content of soil N, P and K in various treatments were documented in the soil over that of control. Mulching of Tephrosia also resulted in markedly higher soil moisture content during drier months of the year. However, the study also indicated need for supplementation of phosphorus from other sources for fulfilling of phosphorus requirement of bearing bael plants under the present planting model.Not Availabl

Not AvailableFarmers in Khunti and Ranchi districts in Jharkhand are benefitting from including biomass yielding plants in their fruit orchards. Mulching of biomass in the plant basins was found to result in significant increase in soil moisture, soil nutrients and organic matter content which is reflected in terms of increased plant vigour and yield.Not Availabl
