(Agricultural Research Communication Centre, 2025) Deepak Kumar Jaiswal; Samantapudi Venkata Satyanarayana Raju; Suresh Choudhary; Sanjay Kumar; V. Manju Vani
Background: The effectiveness of chemical insecticides in comparison to other alternative treatments viz., neem-based biopesticide formulation, chitin synthesis inhibitor, radiation technique and synthetic pyrethroid as seed treatment was studied to manage pulse beetle incidence with a view to determine the best option to prevent seed damage and also to maintain seed quality during storage. Methods: The experiment was carried out under laboratory conditions following completely randomized block design with three replications. Four seed protectant treatments and untreated control was taken to study the effectiveness of the treatments on adult mortality and per cent seed weight loss. The insects were exposed to the treated seeds drawn from the treatment stock at 24, 48, 72, 96 and 120 hours after treatment (HAT). Observations for the study parameters were recorded at 30, 60, 90 and 120 days after storage (DAS) of insects on the treated seeds. Result: The treatment with deltamethrin 2.8% EC @ 1.4 mg a.i./kg seed, diflubenzuron 25% WP @ 1.0 mg a.i./kg seed, neem oil based EC containing Azadirachtin 0.03% @ 6.0 mg a.i./kg seed and UV radiation @ 254 nm exposure for 5 min were found effective against Callosobruchus chinensis in descending order based on adult mortality and per cent seed weight loss. © 2025 , Agricultural Research Communication Centre.

(John Wiley and Sons Inc, 2023) Deo Narayan Singh; Jitendra Singh Bohra; Tej Pratap Dubey; Pushp Raj Shivahre; Ram Kumar Singh; Tejbal Singh; Deepak Kumar Jaiswal
We are frequently exposed to potentially harmful microbes of various types on a daily basis. Our immune system is an amazing collection of unique organs and cells that defends us from hazardous germs as well as certain diseases. It plays a crucial role in protecting the body against external invaders, including bacteria, viruses, and parasites. Maintaining a healthy immune system requires consuming a balanced diet that provides a variety of macro- and micronutrients. By consuming sufficient amounts of water, minerals such as zinc and magnesium, micronutrients, herbs, and foods rich in vitamins C, D, and E, and adopting a healthy lifestyle, one can enhance their health and immunity, and prevent infections. This article provides a comprehensive review of the scientific literature on common foods known for their potential to boost human immunity. The review begins by discussing the various components of the immune system and their functions. It then delves into the current understanding of how nutrition can influence immune response, highlighting the importance of a well-balanced diet in supporting optimal immune function. The article presents an extensive analysis of a range of common foods that have been studied for their immune-boosting properties. These foods include fruits, vegetables, whole grains, and animal-based foods. Each food category is explored in terms of its specific nutrients and bioactive compounds that contribute to immune support. Foods such as milk, eggs, fruits, leafy greens, and spices like onion, garlic, and turmeric contain beneficial compounds that can enhance the immune system's function, activate and inhibit immune cells, and interfere with multiple pathways that eventually lead to improved immune responses and defense. The available literature on the issue was accessed via online resources and evaluated thoroughly as a methodology for preparing this manuscript. © 2023 The Authors.

(EM International, 2016) Ramashanker Singh; Aniruddh Pratap Singh; Rahul Kumar Mishra; Deepak Kumar Jaiswal; S.N. Singh
An experiment was conducted in completely randomized block design with three replications to determine the optimum date of sowing and best harvesting stage for getting the good seed yield of cucumber during winter season of 2007 and 2008. Sowing date of 1st March produced highest percentage of fruit set (46.05), fruits/plant (3.15), fruit length (20.35 cm), fruit diameter (7.17 cm) and fruit weight (398.45 g). Minimum percentage of fruit set and fruit weight was recorded with sowing on 30th April. However, fruits/plant, fruit length and fruit diameter was registered minimum under sowing on 15th January. Harvesting stage did not bring the significant influence on vine length, branches/vine, fruit set and fruit length of cucumber. However, fruit diameter and fruit weight was recorded maximum at harvesting stage 7 (40 DAA). The minimum fruit diameter and fruit weight was recorded with harvesting stage 1 (28 DAA). The seed yield and seed germination was also registered higher value with sowing date of 1st March. The sowing date of 30th April recorded minimum seed yield and seed germination. Harvesting stage 7 (40 DAA) recorded seed yield and seed germination. The minimum value of seed yield and seed germination was recorded with harvesting stage 1 (28 DAA). Economic analysis of data indicated that maximum net return of Rs 17059 and B:C ratio of 2.44 was recorded with sowing date 4 (1st March). However, minimum net return and B:C ratio with sowing date 1 (15th January). Harvesting stage of 7 (40 DAA) registered highest net return and B:C ratio.
Influence of environmental effect on the population dynamics of brown plant hopper, Nilaparvata lugens (Stal) and white-backed plant hopper, Sogatella furcifera (Hovarth) in Varanasi region
(Malhotra Publishing House, 2018) Kamal Ravi Sharma; S.V.S. Raju; Deepak Kumar Jaiswal
Effect of abiotic factors on the population dynamics of brown plant hopper (BPH), Nilaparvata lugens (Stal) and white-backed plant hopper (WBPH), Sogatella furcifera (Hovarth) was studied. BPH population appeared during 30th standard week and reached to its peak during 40th standard week. However, the incidence of WBPH commenced from 32nd standard week and attained peak population levels during 40th standard week. The correlation analysis showed that BPH population has significantly positive correlation with morning RH, evening RH and average RH. Further non-significant positive correlation with minimum temperature, maximum temperature, average temperature and a non-significant negative correlation with rainfall was observed. The correlation analysis of certain abiotic factors with WBPH revealed that the population also showed positive significant correlation with average RH and a positive non-significant correlation with evening RH, morning RH, maximum temperature, minimum temperature and average temperature. However, the population showed negative non significant correlation with rainfall. © 2018 MPH.

(Society for Plant Research, 2017) D.K. Singh; A. Vaishampayan; M.N. Singh; S.K. Singh; Prudhvi Raj Vennela; Varsha Gayatonde; Deepak Kumar Jaiswal; Vaibhav Singh
Knowledge of inheritance pattern is prerequisite for breeding of any disease resistance. In the present experiment the inheritance pattern for Cercospora Leaf Spot (CLS) resistance in Mung bean was studied. Ten genotypes of mungbean were crossed with five genotypes of urd bean to obtain 50 crosses out of which only 15 crosses could be harvested successfully. Six CLS susceptible varieties were crossed with three CLS resistant genotypes of mungbean i.e. HUM-1, ML-1194 and ML-1229 to obtain 18 crosses, however 12 were successful. Out of these, 12 each of F1s, F2s and F3s of intra-specific crosses along with their parents and three each of F1s, F2s and F3s of inter-specific crosses along with their parents were grown in the field in compact family block design with three replications during kharif 2009. Highly susceptible variety HUM-8 was used as infector row for CLS after every two rows of the test entries. The F1 generation of all the intra and inter-spesific crosses showed resistant reaction to CLS. This indicates that resistance was dominant over susceptibility. The segregation ratios in F2 population of all the crosses except HUM-1 x Shekhar-2, was observed to be 3 (Resistant): 1 (Susceptible) and the segregation pattern within the F3 segregating population was also in agreement with the results of F2 observation further confirming the control of single dominant gene for inheritance of resistance to CLS. © 2017, SPR, All Rights Reserved.
Rice sheath mite, Steneotarsonemus Spinki smiley - An emerging pest of rice, in Varanasi District, India
(EM International, 2016) Deepak Kumar Jaiswal; Janardan Singh; A.P. Singh; D.K. Singh
Rice is arguably the world's most important food crop, serving as the staple food for more than half of the world's population (Khush, 2005). Increasing global rice production in a sustainable manner is therefore a critical element in averting food shortages in the future (Normile, 2008). Insects and Mites present, an important constraint in rice production. Rice sheath mite, Survey was conducted in Varanasi district in Kharif season 2011 in the month of October, November and December for possible panicle mite infestation in fine and coarse varieties of paddy. These varieties were monitored for panicle infestation and extent of percentage grains sterility caused by Steneotarsonemus spinki was studied. There was a positive correlation between mite population and percentage of grain sterility in all medium duration varieties and all long duration varieties which were surveyed in the experiment. Lowest mite population and percentage of grain sterility was recorded in the bold seeded varieties, whereas high mite population was found in the long seed varieties. The sterility and chaffyness of grains are always not caused by panicle mite but some time, it is caused by some other insect like, rice Gandhi bug and thrips. In addition to abiotic and biotic stresses the genetic constitution of the plant variety might have played a significant role in regulating the mite population build-up. Very scanty information is available about the interaction of panicle mite with other biotic agents. Much research has to be done to explore the natural enemies like predatory mite which regulate mite population. No variety of paddy was not found to be immune to Steneotarsonemus spinki infestation.
Studies on life history and host preference of pulse beetle, Callosobruchus chinensis (L.) on different pulses
(Malhotra Publishing House, 2019) Deepak Kumar Jaiswal; S.V.S. Raju; V. Manju Vani; Kamal Ravi Sharma
An investigation on the life history and ovipositional preference of C. chinensis reared on five different pulses revealed not much variation between the pulses. The adults exhibited a marked preference for smooth, well-filled seeds for oviposition. The order of preference for oviposition on different pulses for C. chinensis was Cajanus cajan (red gram) > Vigna radiate (green gram) > Vigna unguiculata (cowpea) > Cicer arietinum (chickpea) > Vigna mungo (black gram). © 2019.
