Abstract

Autophagy is a very crucial process in plants and is highly conserved in eukaryotes. Autophagy involves the recycling of cell component to maintain cell homeostasis but also help plants to cope up with adverse environmental stimuli. In this review we have discussed about how autophagy plays role of cell survival in different stress conditions leading to nutrient starvation in plants and also how autophagy can delay apoptosis or programmed cell death in plants.

Abstract

Hematological parameters have been recognized as valuable tools for monitoring fish health induced by any changes in the quality of waters and other related environmental factors. In present study, assessment of heavy metals concentration in fresh water Bhaghar Lake (located at Tahsil-Ramnagar, District- Barabanki, State-Uttar Pradesh, India) concerning their effects on hematological parameters in fish Channa punctatus from it were carried out. The water and sediments of the lake were analyzed for zinc (Zn), copper (Cu), and lead (Pb) concentrations. At the same time, blood parameters of the exposed fish were also examined for any hematological modifications. The results revealed that concentrations of the metals differs significantly (p<0.05) between the lake water and sediments. The concentration (mg/l) of the metals were in the order of Cu>Zn, whereas Pb was not detected in any sample. Blood parameters such as blood cell count (red and white blood cells), hemoglobin, hematocrit, mean cell hemoglobin concentration, mean cell volume, and mean cell hemoglobin were noted to be altered from their normal value in fish (p< 0.05). In conclusion this study indicated that Cu and Zn polluted the lake water and posed their harmful impact on fish health. Further this is the first report on distribution of heavy metals and proximate composition of important edible fish from this fresh water lake in India.

Abstract

Lentil is one of the major Rabi pulse crop grown in India. it’s a rich source of protein, minerals and vitamins for human nutrition and straw is also valued animal feed. Wilt of lentil caused by Fusarium oxysporum f. sp. lentis in the most serious disease of lentil crop. Variability among twenty isolates of Fusarium oxysporum f. sp. lentis (Fol) collected from different lentil growing location of Bundelkhand region in Uttar Pradesh was studied in respect of cultural, morphological characters and pathogenic variability. Isolates of Fol-2, Fol-6 and Fol-16 recorded the maximum colony diameter 90.0, 90.0 and 88.33 mm respectively. Isolates Fol-1,  2, 4, 6, 7, 9, 10, 11, 12, 14, 15, 16 and 17 produced abundant sporulation while remaining isolates produce good sporulation. The isolate Fol-2 and Fol-16 recorded the maximum mycelia dry weight (710.66 and 645.00 mg) respectively and the least mycelia dry weight (238.00mg) was recorded by isolate Fol-8. All the isolates showed significant variation in size of microconidia, macroconidia and septation.

Abstract

Linseed disease incidence survey was conducted in the five district of Eastern Uttar Pradesh, from 2018-2019 to 2019-2020 for two years. The five districts with one Tehsil was selected from Jaunpur, Varanasi, Mirzapur, Chandauli and Azamgarh. Three villages were selected in each district with three farmers fields and the data were recorded separately. Varanasi was severely infected with the maximum average PDI 51.10% followed by Chandauli 51%, Mirzapur 49.18%, Azamgarh 49.06% and the minimum average PDI (45.92%) was recorded in Jaunpur in the year 2018-19. Similarly in year 2019-2020 Azamgarh was found to be most affected district with the average PDI of 51.11% followed by Jaunpur 48.96 %,Varanasi 47.88%, Mirzapur 46.62% and  the minimum average PDI (45.86%) was recorded in Chandauli in year 2019-20. Among the surveyed district the maximum average PDI in the year 2018-19 was found in Varanasi (51.10 %) and minimum average PDI was recorded in Jaunpur (45.92%). In year 2019-20 the maximum average PDI was found in Azamgarh (51.11%) and minimum average PDI (45.86%) was recorded in Chandauli district.

Abstract

The adaptive trial on intercropping was laidout on farmer field in winter season of 2002-2003 under National Agricultural Technology Project, Mainpuri. The main objective was to harvest higher yields of garlic and colocasia in intercropping and obtain the better net return from salt affected soils. The yield of alone garlic was harvested by 105.00 q/ha. Similarly, pure colocasia gave yield by 253.00 q/ha. The  intercropped garlic and colocasia produced 78.00 q/ha and 165.00 q/ha, respectively. The highest net returns of Rs. 643406/ha was found in intercropping of garlic and colocasia. The BCR recorded by 1:5.00 under intercropping of garlic and colocasia. Therefore, newly developed intercropping system proved superior over pure cropping of garlic and colocasia.

Abstract

Integrated pest management technology is a science based decision making process that identifies and reduced hazards  from both pest and pest management related strategies. Worldwide losses due to these pest are estimated to be about 34 % to attainable tomato yield under current production practices. The adoption of IPM technology in tomato using African marigold as a trap crop, root dipping of seedling in  Imidacloprid, soil application of neem cake spraying  bio-pesticide like  HaNPV has been found higher by about 46  %, cost of cultivation has been less by 21 %  and the net returns  have been higher by 119 %. IPM was formlized in 1970 and continue to be exchange to meet the challenges of keeping pest and pest damages to acceptable levels, while minimizing collateral damages. The finding presents the rate of adoption of IPM  technology has increased over the period because of increased yield, gross income in net return in IPM adopters as compared to IPM Non-Adopters. secondly the profit of IPM adopters in terms of net returns was more as compared to IPM non-adopter, Therefore the finding of the study enforced to the adoption of IPM technology.
