A field experiment was carried out during Rabi season of 2020‒2021 and 2021‒2022 at the Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur (Madhya Pradesh) at research field of department of soil science to find out the effect of soil test crop response based long-term fertilization on yield attributing parameters and yield of wheat. The treatments details were T1; Control, T2 ; 120 N: 80 P2O5: 60 K2O kg ha-1 , T3; Target yield of 4.5 t ha-1, T4; Target yield of 6.0 t ha-1, T5; Target yield of 4.5 t+FYM 5 t ha-1; T6; Target yield of 6.0 t+FYM 5 t ha-1 and carried out in Randomized Block Design (RBD) with four replications. Research findings of long term field experiment revealed that application of soil test crop response recommendation for target yield of 6.0 t ha-1+FYM 5 t ha-1 gave maximum earhead length (14.59 and 14.10 cm), number of grains ear-1 (66.46 and 63.30), test weight (41.93 and 41.35 g), grain yield (5568 and 5052 kg ha-1) and straw yield (7315 and 5969 kg ha-1) of wheat. The balanced application of fertilizers by the soil and the crop's needs for potential growth and development may account for the increased yield under the STCR technique with and without FYM. The inclusion of FYM resulted in a potential movement of water, air, temperature, and nutrients in the soil, which may have improved the conditioning of the rhizospheric environment and further raised yield when integrated with STCR. Due to better physical, chemical, and biological characteristics, enhanced microbial activity and the conversion of inaccessible nutrients into available forms, this STCR technique also aids in higher production.

A two-year field experiment was conducted on potato crop to evaluate the bio-efficacy of herbicides, suitable doses and their feasibility with mechanical weed control method in terms of plant height, number of tubers and relative composition of weeds. The experiment was arranged in a randomized complete block design (RCBD) with three replications at the vegetable research farm Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India, during the winter season of 2017-18 and 2018-19. Randomly selected five plants were used as a sample for recording plant height and average number of tubers per plant in each plot. Plant height was measured at 30, 45, 60 DAS and at harvest then averaged and expressed in centimetres. However, the average number of tubers per plant was obtained by counting the tubers from the selected plant at harvest. For calculation of relative composition of weeds, by counting the number of weed species at 1.0 m2 randomly at one place in each plot at 15, 30, 45 and 60 DAS then expressed in per cent. Amongst the herbicidal weed management treatments, Paraquat dichloride 24% SL @ 2.0 L/ha had a significantly taller plants at 45 and 60 DAS and also produces the highest average number of tubers per plant. With respect to the relative composition of weeds, sedges (Cyperus rotundus L.) contributed the most to total weeds, followed by grasses (Cynodon dactylon L.) and broad-leaves weeds (Chenopodium album L., Parthenium hysterophorus L., Sonchus oleraceus L., Anagalis arvensis L., Oxalis spp., Spergula arvensis L.) at 15, 30, 45 and 60 DAS during both years. It is concluded that the application of Paraquat dichloride 24% SL @ 2.0 L/ha control weeds more efficiently thereby it helps in vigorous plant growth thus ultimately increases the number of tubers per plant.

Interestingly more than 50% of the world’s area is rainfed and approximately 80% of maize is cultivated under rainfed condition where selection of cultivar and management of nitrogen have major impact on production. The aim of this study was to evaluate the growth, phenology, yield and quality parameters of maize as influenced by variety and nitrogen scheduling under rainfed condition. For this, a field experiment having two factors was laid out in a factorial randomised block design and replicated three times. The first factor was variety, i.e., V1 (JM 216) and V2 (JM 218), and the second was six nitrogen scheduling, i.e., N1 to N6, in which nitrogen splitting was done based on 30-years of average rainfall data. Variety JM 218 and N5 [40 kg N as basal followed by (fb) 2 splits of 40 kg N and 38.8 kg N at 30 and 52 days after sowing (DAS) and 1% N foliar spray at 40 DAS] nitrogen scheduling were found promising under rainfed situation because it recorded maximum value of growth parameters, yield attributes, grain yield and quality parameters (protein, mineral and dickson quality index). Thus, it can be inferred that JM 218 and N5 nitrogen schedule would be a better choice than alternative options.

Background: Dryland is characterised by drought/dry spell (s) of 10 to 15 days and is the main reason for decline in soybean production. The aim of this study was to develop a strategy of drought amelioration by using foliar sprays and enhancement of yield, quality, energetics and carbon footprint. Methods: A field experiment was carried out at Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, College of Agriculture, Indore, (M.P.) during 2017-18 under spilt-plot design having two main plot treatments viz., foliar application at dry spell (F1), foliar application after dry spell (F2) and seven sub plot treatments i.e. different variants of foliar sprays (DVFS). Different growth, yield, quality, energetic and carbon footprint traits were recorded. The data were analyzed using standard statistical procedures. Result: The highest growth, yield, quality and energetic parameters were recorded for F1 as compared to F2. In case of DVFS, foliar application of water soluble complex fertilizer 19:19:19 (NPK) @ 0.5% + 0.5% ZnSO4 (T4) produced maximum values for growth, energetics, carbon footprint, oil (22.5%) and protein (43.1%) content as well as produced maximum yield.

A field experiment was conducted during Rabi season of 2020-21 and 2021-22 at Livestock farm, Department of Agronomy, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh, India to study the Influence of different sowing dates and nutrient management on yield attributes and yield of wheat (Triticum aestivum L.). The twelve treatments consisting of four sowing dates viz. 25th October, 05th November, 15th November and 25th November as main plot treatments and these were superimposed with three nutrient management i.e. Recommended Dose of Fertilizer, 150% RDF + FYM 15 t ha-1, 150% RDF + FYM 15 t ha-1 + Growth Regulators as sub plots and carried out in split plot design with three replications. On the basis of two year study it is evident that sowing of wheat on 5th November was found to be most suitable than rest of the sowing dates as it recorded significantly higher number of effective tillers (399.91 and 411.94 m-2), length of earhead (10.61 and 11.15 cm), number grains earhead-1 (45.75 and 46.86), grain (5494 and 5497 kg ha-1) and straw yields (7033 and 7128 kg ha-1) compared to rest of the sowing dates except 25th October during both the year. Among the nutrient management, application 150% RDF + FYM 15 t ha-1 + Growth Regulators recorded significantly higher number of effective tillers (405.51 and 416.72 m-2), length of ear head (9.99 and 10.50 cm), grains earhead-1 (45.89 and 46.60), grain (5735 and 5866 kg ha-1) and straw yields (7343 and 7514 kg ha-1) as compared to rest of the nutrient management during both the years.

A field experiment was carried out during Rabi season of 2020‒21 and 2021‒22 at the Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur research field to find out the effect of long term soil test crop response based nutrient management in wheat (Triticum aestivum L.) on physical properties in a Vertisol. The treatments details were T1; Control, T2; 120 N: 80 P2O5: 60 K2O kg ha-1, T3; Target yield 4.5 t ha-1, T4; Target yield 6.0 t ha-1, T5; Target yield 4.5 t + FYM 5 t ha-1, T6; Target yield 6.0 t + FYM 5 t ha-1 and carried out in Randomized Block Design (RBD) with four replications. The results indicated that the STCR based treatment with target yield 6.0 t ha-1 along with application of FYM 5 t ha-1 recorded lowest bulk density (1.31, 1.33 and 1.35 Mg m-3) and particle density  (2.62, 2.62 and 2.63 Mg m-3) at 0-15, 15-30 and 30-45 cm soil depth. The treatment with target yield 6.0 t ha-1 along with application of FYM 5 t ha-1 recorded highest porosity (50.07, 49.28 and 48.52 %) as well as water holding capacity (44.42, 40.16 and 37.44 %) at 0-15, 15-30 and 30-45 cm soil depth. The long term study based on STCR clearly demonstrated that balanced fertilizer application not only improved the physical properties of soil but also save the fertilizer without impairing soil health.

In today’s world everything is online which also increases the chances of fraud. There are approximately 36.4 percent fraud related to commercial cards which include credit card, debit card, etc. In 2022 there are 64 million people who uses credit card to initiate the transaction, therefore they are also prone to the card fraud.

Background: Nearly all anaesthetic agent decreases renal and hepatic blood flow, so anaesthetic agents should be selected properly in patients particularly with pre-existing renal and hepatic impairment. The present study conducted to evaluate the effect of acepromazine, midazolam and dexmedetomidine as pre-anaesthetic agent followed by induction with propofol and maintenance with isoflurane on kidney and liver function of client-owned female dogs undergoing elective ovariohysterectomy. Methods: Thirty-two clinically healthy female dogs were randomly divided into four groups with ten animals in the groups A and B and six animals in groups C and D for elective ovariohysterectomy. Animals were premedicated with acepromazine-butorphanol in group A, midazolam-butorphanol in group B, dexmedetomidine (I/M)- butorphanol in group C and dexmedetomidine (I/V)- butorphanol in group D. Animals in all four groups were induced (till effect) with propofol and maintained with isoflurane. Result: All the groups showed non-significant marginal decline in BUN and serum creatinine at 5 minutes after pre-medication. Serum AST and ALT were non-significant decreased in groups A and B and non-significant increase in groups C and D during observations. Serum albumin and globulin gradually but non-significantly decrease in group A after premedication to T20 during anesthesia with isoflurane, then gradually increase upto extubation, but values remained lower in comparison to base values.
