Effect Of Crop Establishment Methods And Weed Control Treatments On Yield, Weed Density, Weed Dry Weight, Weed Index And Weed Control Efficiency In Rice

Paper ID- AMA-18-01-2022-11028

A field experiment was established at Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh to find out a suitable crop establishment method (direct seeded rice, system of rice intensification, transplanted rice) and herbicidal applications (bispyribac-sodium at 20 g ha-1, fenoxaprop-p-ethyl at 93 g ha-1, fenoxaprop-p-ethyl at 56 g ha-1) for optimum growth, weed flora, water use efficiency and higher yield in rice. Experiment was laid out in a split plot design with three replications. Herbicide was sprayed at 25 DAS/DAT. Among weed control treatments, hand weeding exhibit maximum grain yield. Among herbicidal application, bispyribac sodium at 20 g ha-1 observed higher crop growth and yield than fenoxaprop-p-ethyl at 93 g ha-1 and fenoxaprop-p-ethyl at 56 g ha-1 maximum plant growth parameters. Among all herbicidal treatments, that post-emergence application of bispyribac-sodium at 20 g ha-1 gave significantly lower total weed density, weed dry weight and higher weed control efficiency at all the stages. The minimum weed index was noted under bispyribac-sodium at 20 g ha-1 in System of Rice Intensification (SRI) treated plots.

Simulation and Experiment Study on the Tobacco Leaves Harvesting Mechanism

Paper ID- AMA-18-01-2022-11027

Tobacco leaves are mostly harvested manually, which consumes a lot of time and labor. To develop the tobacco leaves harvester, the harvesting mechanism which is the core component of the harvester was studied. Firstly, the mechanical harvesting model of tobacco leaves was established based on ADAMS software. The operating parameters that affect the mechanical harvesting of tobacco leaves are the rotation speed of the harvesting tool, the feeding speed of the harvesting tool, and the installation angle of the harvesting tool. To increase the harvesting rate and reduce the breakage rate, these three operating parameters were used as variables for simulation experiments. Through the analysis of the simulation experiments, nine groups of appropriate operating parameters were obtained, which can be used as guiding parameters for actual harvesting work. Secondly, the tobacco leaves harvesting test-bed was designed and manufactured to verify the simulation results. Based on the simulation results, orthogonal experiments were designed. In addition, two groups of harvesting tools with different hardness were used for experiments. The orthogonal experiments results revealed the effects of the rotation speed, the feeding speed, the installation angle, and the hardness of the harvesting tool on the harvesting rate and the breakage rate. Finally, the optimal combination of operating parameters was obtained, which is 0.9 m·s-1, 175 r·min-1, 8º. When the hardness of the harvesting tool is 56 HA, the mechanical harvesting of tobacco leaves can reach the harvesting rate of 90% and the breakage rate of 14%.

Effect of fertility, zinc and cow urine levels on wheat and its’s residual effect on succeeding fodder maize under dairy based integrated farming system of Varanasi tract

Paper ID- AMA-18-01-2022-11026

A field experiment was executed in line with split plot deign in triplicate in two successive years of 2016-17 and 2017-18 at the Agricultural Research Farm, Banaras Hindu University, Varanasi (U.P.) to contrast the effect of cow urine application at varying fertility and zinc levels on growth and yield of irrigated wheat (Triticum aestivum L.) and their residual effect on fodder maize (Zea mays L.). Two fertility levels (100 and 75% RDF), three zinc (0, 5 and 10 kg Zn ha-1) and cow urine levels (0, 12000 and 8000 l ha-1 equally applied at sowing and CRI and spike emergence) were applied. RDF at 100% in previous wheat evinced significantly maximum (p=0.05) rally in green and dry fodder yield of fodder maize through highest plant height and number of green leaf plant-1 as well as net returns with exception of SPAD value (Leaf chlorophyll content). In parallel, fodder maize response in the matter of green and dry fodder yield via highest plant height and number of green leaf plant-1 as well as net returns except SPAD value (Leaf chlorophyll content) was significant at 10 kg zinc ha-1. Nevertheless, it could not differ at the significance level with 5 kg Zn ha-1. However, various cow urine levels applied in preceding wheat crop were not exerting any residual effect on growth, yield and economics of maize, suggesting that residual effect of 100% RDF, 10 kg Zn ha-1 applied to previous wheat was remunerative to fodder maize under similar soil and weather conditions.

Effect Of Organic Amendments On Mustard Grown In Chromium Contaminated Soil

Paper ID- AMA-18-01-2022-11025

A pot experiment was conducted to evaluate the effect of organic amendments on reduction and phyto-availability of chromium in mustard crop (Brassica juncea L.) during 2017-18 at Banaras Hindu University, Varanasi. Different organic amendments sources viz. FYM, vermicompost, poultry manure and sewage sludge were tested at four level of chromium (0, 50, 75 and 100 ppm) total 20 treatment combinations in complete randomized design and replicated thrice. The application of 100 ppm Cr + PM @ 5 ton ha-1 recorded significantly minimum of chromium content in root, shoot and seed of mustard (19.66, 11.63 and 2.127 mg kg-1, respectively), chromium content in post harvest soil (0.833 mg pot-1) and transfer factor (TF) of root, shoot and seed of mustard (21.16, 7.02 and 0.437, respectively) then other treatment combinations. The application of 100 ppm Cr + PM @ 5 ton ha-1 recorded significantly higher of Cr accumulation in root, shoot and seed of mustard (36.91, 61.16 and 0.550 mg pot-1, respectively) and translocation ratio of shoot and seed of mustard (0.634 and 0.113, respectively) then other chromium level and organic amendment combinations.

Identifying Optimum Rate of Cow Urine at Varying Fertility and Zinc Levels and their Impact on Wheat (Triticum aestivum L.) under Irrigated Conditions of Varanasi

Paper ID- AMA-18-01-2022-11024

The continuous use of inadequate and imbalanced nutrients in the exhaustive rice-wheat systemlead to deterioration of soil fertility and soil health in Indo-Gangetic alluvial belt. In such systems, uses of concentrate organic nutrient sources as a renewable source of plant nutrients is assuming importance as organic sources integrated with inorganic fertilizersimprovescrop productivity while sustaining soil health. Therefore a field experiment was plannedto assess the cow urine effects (U2 - 12000 l ha-1 equally distributed at sowing, CRI, and spike emergence, U1 - 8000 l ha-1 equally applied at sowing and CRI and U0 - 0 l ha-1) at varying fertility (100% and 75% RDF) and zinc levels (0, 5 and 10 kg Zn ha-1) on wheat under irrigated conditionsof Varanasi in split plot design. After two years,maximum shoot dry weight m-1 row length, grain yield, straw yield, protein content, protein yield, nutrient content and uptake by grain and straw were statistically obtained with 100% RDF (F1) over 75% RDF (F2). Plants grown under 10 kg zinc ha-1resulted significantly higher values of above parameters though remained comparable to 5 kg Zn ha-1. A significant increase was obtained with respect to NPK & Zn uptake by grain and straw and protein, grain and straw yieldwith each increment of cow urine level, recording maximum at 12000 l cow urine ha-1.Within the levels of cow urine applied, 11.14% and 10.20% increase in 2016-17 and 10.31% and 9.20% increase in 2017-18 wererecorded with 12000 and 8000 l cow urine ha-1over control, respectively.
