Effects of rising temperature and CO2 concentration on reference evapotranspiration and identification of significant governing meteorological variables in a semi-arid irrigated region
The present study was conducted to identify the key meteorological variables that have a significant effect on reference evapotranspiration (ET0) by using principal component analysis (PCA) and sensitivity method in a irrigated semi-arid region of North-West India (Karnal). Further, the climate change effect on ET0 was studied with the projected increase in temperature ranging from 1 to 5°C and CO2 concentration between 330 to 660 ppm. The investigation of PCA indicated that temperature and sunshine hours had greater linearity with ET0 with eigen values of 3.81, 3.70, and 3.18 in annual, summer, and winter periods, respectively. While, sensitivity analysis revealed that ET0 had significant variability with temperature, followed by sunshine hours, relative humidity, and wind speed. It was also found that changes in ET0 by increased temperature of 1 and 5°C is neglected the effect of 430 ppm and 660 ppm CO2 concentrations, respectively Hence, elevated temperature and CO2 concentration had opposite effects on ET0 and the combined effect of elevated CO2 and temperature contradicts the individual effect of each other on ET0.
Validation of copper oxy chloride and streptocycline against BLB of cluster bean incited by Xanthomonas campestris pv. cyamopsidis
Guar is an important dry land Kharif crops of Haryana and India is the largest cluster bean producer of the world with approximately 80 percent contribution in production. The crop surviving under harsh conditions is very sensitive to bacterial leaf blight incited by Xanthomonas campestris pv. Cyamopsidis causing devastating losses. Based on different technology developed for the management of this disease, first the premeditated effect of seed treatment was experienced for effect on disease appearance and germination parameters related to yield points. Seeds of cultivar HG 2-20 and HG 563 were also soaked in the streptocycline solution at different temperature regimes for different time intervals in vitro. The soaking duration of 30 minutes at 250C was optimum for seedling length and overall seedling vigour. In vivo, the lowest disease severity at 45 DAS was recorded when seeds were soaked in streptocycline solution for 30 minutes or more. The fungicides namely copper oxy chloride along with antibacterial streptocycline was tested at different concentrations on guar cultivar HG 2-20 at two locations through seed treatment and foliar applications during Kharif 2017 and 2018. At farmers’ field, lowest disease severity and higher benefit cost ratio was recorded in case of copper oxy chloride @ 0.2% and streptocycline @ 75 ppm with maximum increase in yield over untreated check.
Influence of different inorganic and organic fertilizer doses on strawberry growth under hydroponic system
A field experiment is conducted at agriculture field of School of Agriculture, Lovely Professional University Phagwara, Punjab. This research work duration period was Oct, 2016 to 15, March 2017. In this experiment we determined the influence of different nutrients concentration on strawberry plants and compare the hydroponic system with the soil experiment in pot system. In this research takes the nine treatments in soil and seven treatments in hydroponic system. The experiment is carried out in RCBD. And the results show the many variation in different growth parameter due to the environment factors and nutrients concentration. In soils T9 (25% RDF + 75% FYM) shows the best yield/plant and good results in the growth parameter. But in hydroponics system the T6 (30% sewage sludge + 70 % cocopeat) shows the best yield/plants and best vegetative growth as compared to the soil treatments.
Biochemical changes induced in mungbean germplasm (Vigna radiata (L.) Wilczek) against mungbean yellow mosaic virus (MYMV) disease
Mungbean (Vigna radiata (L.) Wilczek) is a very ancient annual crop and India is the world’s largest producer of mungbean with approximately 30% of global output of 5.3 million t. Various diseases of mungbean are anthracnose, rust, cercospora leaf spot, powdery mildew, stem necrosis, dry root rot, leaf crinkle and yellow mosaic disease (MYMV). Out of all diseases, MYMV disease is one of the most prevalent and destructive diseases. MYMV a member of Geminiviridae family and transmitted by whitefly (Bemisia tabaci Genn) in persistent manner. Ten mungbean genotypes were screened against MYMV diseases (MH 1801, MH 1850, MH 1851, MH 318, MH 215, MH 125, MH 1811, MH 1870, MH 1814 and SML 1082). The current study was aimed to know about changes in concentrations of biochemical parameters (chlorophyll content, carotenoids, Orthodihydroxy phenol, phenol content, flavanol and total soluble sugar) at different stages of crop infected by MYMV and disease severity. The disease severity and biochemical changes were estimated at weekly and fortnight interval respectively. The chlorophyll content and carotenoid content were higher at 25 DAS and 40 DAS but from 40 DAS to 55 DAS chlorophyll content was decreasing. Higher total phenol content estimated at initial stage, i.e. at 25 DAS and 40 DAS. It decreased at 40 DAS and 55 DAS. However, Orthodihydroxy phenol and flavanol content was observed decreasing gradually from 25 DAS to 55 DAS. Maximum phenol content and flavanol content was recorded in MH 1851 followed by MH 215.
A review on Epidemiology and various management methods of brinjal fruit rot disease
Eggplant (Solanum melongena L.) commonly known as brinjal belongs to the family Solanaceae. Brinjal is particularly grown in sub-tropical and tropical regions of the world. It is the most important vegetable in India and is described as “king of vegetables” due to its wide usage in Indian foods. The brinjal crop succumbs to various biotic and abiotic stresses at various stages of growth. There are several environmental, edaphic and plant factors which results in lower production and productivity in brinjal. It is attacked by many fungi, bacteria and viruses. Among various stresses, diseases are the prominent factor in decreasing the production in brinjal. The major diseases which reduces the yield in brinjal is Phomopsis fruit rot caused by Phomopsis vexans. The pathogen is seed-borne and produce large number of conidia which causes infection in brinjal. The devastating diseases such as phomopsis blight should be controlled effectively for increasing its marketability and consumption. The effective fungicides which shows highest average mycelial growth inhibition are carbendazim, propiconazole and hexaconazole among systemic fungicides. An increasing consciousness about environmental pollution due to fungicides and development of fungicide resistance in pathogen population has challenged the plant pathologist to search for eco-friendly tools for Phomopsis vexans management. Seed treatment and spraying of Trichoderma harzianum and Pseudomonas fluorescens are very effective against Phomopsis vexans. Use of botanicals, bioagents are most commonly practiced now a days to avoid the problems created by the fungicides.
