Evaluation of Zinc Soil Fractions, Nutrient Status in Soil , Yield of soybean and safflower influenced by long-term effects of Manuring and Inorganic Fertilizers in Soybean and Safflower Cropping Sequence in Typic Haplusterts
The cultivation of soybean – safflower cropping sequence for sixteen years showed the significant variations of different zinc fractions due to different treatments of long term fertilizers in soil were monitored for two consecutive years of 2018-19 and 2019-20 on different fractions of zinc, nutrient status of soil and yield of soybean and safflower in Typic Chromustert of soil. The study encompasses varying chemical fertilizer levels of optimum fertilizer rate (30, 60 and 30 kg ha−1 N, P and K, and 60 and 40 N and P kg ha−1 respectively, for both the crops. The treatments were application of 50% NPK, 100% NPK, 150% NPK, 100% NPK + hand weeding (HW), 100% NPK + Zn, 100% NP, 100% N, 100% NPK + 5 t FYM ha−1, 100% NPK(-S) and unfertilized control. The pooled data on grain (1505 Kg ha-1), and straw (3115 Kg ha-1), yields of soybean as well as grain (1169 Kg ha-1) and straw yields (4092 kg ha-1) of safflower were highest with 100% NPK + FYM @ 5 t ha−1 and this treatment also gave significantly maximum availability of nitrogen (280 kg ha-1), phosphorous (19.02 kg ha-1) and potassium (798.50), respectively in soil than all the other treatments at harvesting stage. Among the different treatments of long term fertilization 100% NPK + Zinc gave significantly maximum zinc fractions of Exchangeable zinc, carbonated zinc, organically bound zinc, manganese oxide bound zinc, amorphous Fe and Al oxide bound zinc, crystalline Fe and Al oxide bound zinc, residual zinc and total zinc in 100% NPK + Zinc @ 25 kg ZnSO4 /ha followed by 100% NPK + FYM @ 5 t ha−1 and 150% NPK after harvest of safflower.
Potential Analgesic, Anti-inflammatory and Antioxidant Activities OF hydroethanolic Extract OF Crataegus oxycantha L. Berries
The present study was designed to evaluate the antioxidant, anti-inflammatory and analgesic activities of hydroethanolic ex¬tract from Crataegus oxycantha L. fruit, a plant widely used as natural treatment of cardiovascular diseases in folk medicine. The antioxidant activity was determined by Phosphomolybdate, H2O2 radical scavenging, and β-carotene bleaching assays. The anti-inflammatory was evaluated by croton oil -induced ear edema in mice and analgesic activity was carried out by acetic acid induced writhing in mice. The polyphenolic and flavonoids contents of C. oxycantha extract were found to be 56.5 ± 2.49 mg EGA/g of dry extract and 0.43 ± 0.09 mg EQ/ g of dry extract, respectively. Whereas the tannins content was 48. 30 ± 0. 9 mg ETA/ g of dry extract. C. oxycantha ethanolic extract showed a good ability to scavenge hydrogen peroxide with an IC50 value of 2.695 ± 0.121 ± mg / ml. In addition, this extract exhibited a high total antioxidant capacity (TAC) in molybdate phosphate test (EC50 of 0.145 ± 0.006 mg / ml). The administration of C. oxycantha extract at the dose of 200 and 600 mg/kg caused significant inhibition of inflammation in croton oil-induced ear edema in mice. In acetic acid-induced writhing model, C. oxycantha extract reduced abdominal cramps at a dose of 600 mg/kg with 69.92% of inhibition. The results suggest that the polyphenolic extract of C. oxycantha L. possesses antioxidant, anti-inflammatory and analgesic activities which could be tested as drug candidates against oxidative and inflammation-related pathological processes.
Effect of Histidine Supplementation on Growth Performance Characteristics, Hemato-biochemical Profile and Economics of Broiler Production
An experiment of five w weeks duration was conducted at Livestock Farm Complex, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya to access the impact of histidine supplementation on growth performance, hemato- biochemical profile and economics of broiler production. Total 200 day old chicks were randomly divided into four dietary treatment and each group was further redistributed into five replicates containing 10 chicks in each i.e. control group (T1) with basal diet regimen, T2 group (Basal diet+ Histidine @0.05%), T3 group (Basal diet + Histidine @ 0.10%), T4 group (Basal diet+ Histidine @0.2%). Body weight, body weight gain, average daily gain, growth rate, feed intake, gain feed ratio, performance index, hemato-biochemical profile and economic efficiency were assessed. In the third, fourth and fifth weeks T3 group broilers body weight were significantly (P<0.05) higher than T1, T2 and T4 group. The average total feed intake as well as daily feed intake during the entire experimental period were significantly (P<0.05) lower in T3 group, with respect of control group. The T3 group birds had significantly (P<0.05) higher gain to feed ratio and performance index, as compared to control group. The serum glucose, total protein, albumin and globulin values were significantly (P<0.05) higher in histidine supplemented birds in all the dose regimen, as compared with control group. The cost of production of T1, T2 and T3 groups birds were comparable (P>0.05) but significantly (P<0.05) higher than T4 group. The birds supplemented with 0.10% histidine had significantly (P<0.05) higher feed price ratio, profitability and economic efficiency index, as compared with control group. The observation of break even output was lowest (P<0.05) in T3 and highest (P<0.05) in T4 group. So, it might be concluded that, the dietary supplementation of histidine @ 0.10 % has ability to improve the performance of broiler chickens.
Physical, Functional and nutritional quality characterization of microencapsulated Ber (Ziziphus mauritiana L.) fruit powder
Limited availability, lower shelf life, and lack of suitable technologies are major drawbacks for the limited utilization of Ziziphus fruit in processing industry. This study was carried out with the aim to enhance the shelf-life and retain the economic importance of Ziziphus by using spray drying process for Ziziphus powder production. Maltodextrin used as wall material in different concentrations and inlet air temperature were taken as independent variables to study their effect on major powder responses i.e., powder yield, water activity, color properties, vitamin-C, total flavonoid content, and total antioxidant activity. Lower encapsulant quantity (10-15%) was inefficient in limiting the degrading impact of temperature on bioactive compounds. Higher encapsulant quantity of 25% had masking effect on bioactives concentration and their associated activity retention. Therefore, 170°C inlet air temperature, 20% maltodextrin concentration and 60ml/h feed flow rate were optimized to obtain 22.30 ± 3.09% for producing commercially viable powder with lowest water activity (0.295 ± 0.02), best color retention (L* 88.52 ± 0.70, a* 1.13 ± 0.49, b* 12.25 ± 0.62), highest bioactive retention (vitamin C 14.56 ± 0.59 mg/100g, flavonoid content 388.00 ± 0.46 mg/100g) and associated functional activity (antioxidant activity 1.89 ± 0.56 to 2.10 ± 0.50/g).
EFFECT OF MULCHING PRACTICES, VARIETIES AND FERTILITY LEVELS ON PHYSIOLOGICAL GROWTH PARAMETERS OF CLUSTERBEAN
A field experiment was conducted during the kharif season of 2013 and 2014 to evaluate the effect of mulching practices, varieties and fertility levels on physiological parameters of clusterbean at the Research Farm, College of Agriculture, Gwalior. The results revealed mulching practices, varieties and fertility levels on physiological parameters of clusterbean that increased the value of CGR, AGR and LAI up to 90 DAS, RGR up to 60 DAS and LAR up to 30 DAS growth stage and then decline up to maturity. The values of dry matter, CGR, RGR, AGR and leaf area index were recorded higher with plastic mulch, HG-563 and 75% RDF +VC 5t/ha. over remaining mulch, varieties and fertility levels. While leaf area ratio (LAR) was recorded maximum in Control (N0P0K0) over other fertility levels at all growth stages.
