An experiment was conducted to investigate the comparative performance of commercial broilers fed KemTrace (mineral propionate) with other organic minerals. The feeding trial was conducted for a period of six weeks with 672 chicks allotted to seven experimental groups each with 12 replicates and each replicate consisting of 8 birds in a completely randomized design. The diets of the treatments were : T1-Basal diet with Blend A (Inorganic- sulphates, oxides and carbonates) @1000gm/mt; T2-Basal diet with Blend B (Proteinates) @500 gm/mt. ; T3- basal diet with Blend C (Propionates with antioxidants)@250 gm/mt.; T4- Basal diet with blend D (same as T3 but produced in different process) @350 gm/mt.: T5-Basal diet with Blend E (Propionates, Fumarates with antioxidant) @250gm/mt.: T6-Basal diet with Blend F (Propionates, Fumarates with antioxidant) @500 gm/mt.; T-7 Basal diet with blend G (Butyrates, Propionate, Fumarates with antioxidants) @500 gm/mt of feed. Parameters like growth performance, carcass yield, immune status and trace mineral retention in organs were observed in the broilers. The collected data were analysed using SPSS software Programme version 17.0 and interpreted. The commercial broilers supplemented with metal propionate form of organic mineral performed better than other organic mineral supplementations on growth performance and immune response. Metal propionate form of organic mineral supplemented broilers also showed significantly higher performance on carcass quality and cost economics than other organic mineral supplementations.
A field experiment on grafting three cultivars of brinjal, namely GJB-3, GAOB-2 and Suratiravaiya onto the rootstock of Solanum torvum Swartz was conducted to find out the interaction effect of different grafted and non-grafted varieties and different mulching on plant survival and other horticultural parameters. The variation due to different mulching treatment was found significant for growth and yield parameter. Significantly, highest plant height (113.80) cm), No. of branches per plant (8.97), No. of fruit per plant (12.94), average fruit weight (86.26 gm), marketable fruit yield (1.10 kg/plant and 29.76 t/ha) and lowest days to 50% flowering at TP (49.30), days to first picking (67.96) and days to last picking (173.20) were recorded in treatment M2 (Silver Mulch). Similarly, variety variation was observed significant for growth, yield and yield attributes. Significantly, maximum average fruit weight (107.73 gm), marketable fruit yield, (1.25 kg/plant and 34.78 ton/ha) were recorded with variety (V1): GJB-3 grafted on solanum torvum, whereas, highest plant height (121.18 cm), no. of branches/plant (9.95) and no. of fruits per plant (15.68) were noted in V3: Surtiravaiya grafted on solanum torvum and lowest days to 50% flowering (43.94%), days first picking (67.28) and days to last picking (170.56) were registered with V2 (GJAB-2 grafted on solanum torvum). Interaction effect was found non-significant for maximum character except no. of branches/ plant, no. of fruit per plant and marketable fruit yield. Variation between treatments of mulching was recorded significant for quality and insect pest infestation parameters. Significantly, highest TSS (7.67oB), plant survival (87.59%) and lowest acidity (0.171%), fruit and shoot borer, jassid and white fly infestation (23.24%, 21.81% and 63.59% respectively) were registered with M2 (Silver mulch). For varieties, variation was recorded significant for quality and insect pest infestation parameter. Maximum TSS (8.24oB), minimum acidity (0.102) and fruit and shoot borer infestation (19.72%) were recorded with V3. Whereas, highest plant survival (92.00%) and lowest Jassids and white fly infestation (15.11% and 62.67%) were noted in V2. Interaction effect for quality and insect pest infestation parameters were noted non-significant except TSS and acidity. The farmers of South Saurashtra Agro-climatic Zone growing brinjal are recommended to use variety GJB-3 grafted on Solanum torvum (wild brinjal) with silver black mulch (25 micron) for higher yield.
Chickpea is an important Rabi food legume grown throughout the world. India is the largest producer and contributes 2/3rd of total production of global chickpea. Productivity of chickpea in India is lesser than some other countries due to various factors. Cultivation of chickpea crop is adversely affected by both biotic and abiotic stresses. Among biotic stresses collar rot is an important limiting factor for the production of chickpea. Collar rot incited by Sclerotium rolfsii is an economical disease of chickpea and causes 10-30 per cent yield loss annually. The disease appears moderate form every year in chickpea growing areas. It causes heavy losses in chickpea sown after harvesting of rice having stubbles in cultivated fields. Keeping in view of the serious and economical losses caused by the pathogen, the present study on assessment and identification of germplasm for resistance source and better yield performing genotypes have been conducted during Rabi 2021-22 at Bihar Agricultural University, Sabour, Bhagalpur, India. In the present investigation, two hundred fifty three germplasm were evaluated for their yield and resistance against collar rot under natural sick plot field conditions. Due to continuous growing of breeding material in same field for the last many years, it has high inoculum load. Among evaluated germplasm none of them were found resistant against collar rot disease. However, two hundred fourteen germplasm lines exhibited moderately resistant, twenty two moderately susceptible, eleven susceptible and six genotypes identified as highly susceptible. All germplasm were also assessed for their yield and yield attributing traits in which ICCV 94954 (2937.50 kg/ha), GL-15209 (2845.84 kg/ha), GL-15131(266.66 kg/ha), CSJ 1065 (2645.84 kg/ha), IPC 2011-141 (2595.84 kg/ha), GNG2475 (2591.66 kg/ha) and RSGD 1174 (2562.50 kg/ha) showed moderately resistant reaction as well as better yield performing genotypes which may be utilized for breeding programme for the development promising entries against collar rot disease.
In the field of agriculture, machines are very important tools to increase the productivity of good quality products. Therefore, it is necessary to develop such technological machines, constantly updating the working mechanism. The mower is one of those machines that cutting mechanism is a very important working device, which must been continuously improved. Therefore, a new mower’s double cutter-bar is designing to improve the technological and mechanical performance of the mower. This paper concerns basic parameters of mower’s double cutter-bar mechanism. A kinematic study concerning the double cutter bar mechanism using the method of closed contours, therefore analytical equations are developed, describing the trajectory of the knives, the speed and the acceleration, while also determining the necessary driving power as well as the device power supply and pinch, thus justifying the basic parameters of this mechanism. To validate these mathematical expressions experimentally, a prototype of this mechanism is made within the Kazakh Institute for Scientific Research on Mechanization and Electrification of Agriculture allowing to adjust and improve several design and technology parameters. The correctness of the theoretical premises is confirmed by testing the developed prototype mechanism in agricultural fields.
Hertia cheirifolia L. is a medicinal plant belonging to Asteraceae family. It is traditionally used to treat gastrointestinal ailments, infections, and spasms. The aim of this study is to evaluate the oral acute toxicity of aqueous extract from Hertia cheirifolia on female Albino wistar mice. Animals were divided into three groups, the first group received distilled water and was used as control; Mice of the second and third groups received the plant extract at doses of 2g/kg and 5g/kg body weight of animals, respectively. The mice were monitored for 14 days for their general behavior, adverse effects and mortality. The results showed that no death or toxic signs were observed, no changes were seen in food consumption, body weight and organ weight in the treated animals compared to the controls. However, an increase in AST and ALT levels was recorded in mice treated with the extract.
