Effect of rhizobium, PSB and p-levels on growth, yield attributes and yield of urdbean (vigna mungo l.)
(Journal of Pure and Applied Microbiology, 2016) Surya Kant; Achin Kumar; Satendra Kumar; Vipin Kumar; Yogesh Pal; Anil K. Shukla
A field experiment was conducted in kharif 2011 on urdbean genotype T-9. The experiment was laid out in randomized block design with three replication and thirteen treatments. Some microorganisms have capable to convert the insoluble phosphorous to an accessible form and increase the growth and yield attributes viz, plant height, number of branches plant-1, nodulation, dry matter accumulation plant-1, number of pods plant-1, test weight (g), grain yield, straw yield and biological yield (qha-1) of Urdbean. All these characters were recorded higher in treatment T13 by application of (75 kg ha-1 P2O5 + PSB + Rhizobium.) as compared to all other treatments. However, combination of rhizobium, PSB and P levels had proved significant influence on plant growth, yield and its attributing traits in Blackgram.
Influence of mulching and NPK levels on growth, yield and economics of pearl millet in bael based agri-horticultural system under rainfed Vindhyan region
(Technoscience Publications, 2015) Sandeep Kumar; Achin Kumar; Sumit Rai; Suryakant; Rajesh Singh
A field experiment was conducted during kharif season of 2013 to find out the effect of mulching and NPK levels on pearl millet (Pennisetum glaucum) in bael (Aegle marmelos) based agri-horti system under rainfed condition of Vindhyan region. There were twelve treatment combinations comprised of three levels of mulching (no mulch, wheat straw mulch and dust mulch) and four levels of RDF NPK (50%, 75%, 100%, 125%). The experiment was laid out under split-plot design with three replications. Significant improvement was recorded in growth and yield attributes viz., plant height, number of leaves per plant, number of tillers per plant, dry matter accumulation per plant, number of ears per plant, ear length, number of grains per ear, 1000-grain weight, grain yield, stover yield, harvest index (%), nutrient uptake and economic returns. Significantly higher yield of pearl millet (1908 kg/ha) was observed in the plot that received 125% RDF, which was found at par with the 100% RDF and in case of mulching, the maximum yield was observed with dust mulch (1942 kg/ha) than all other treatments. The application of dust mulch and 125% of the recommended dose of fertilizer (RDF) NPK (T12) treatment have distinct superiority as compared to all other treatments under bael based agri-horti system and more suitable for moisture conservation practice in pearl millet. © 2015, Technoscience Publications.

Organic Amendments Application Increases Yield and Nutrient Uptake of Mustard (Brassica Juncea) Grown in Chromium-Contaminated Soils
(Taylor and Francis Inc., 2020) Vipin Kumar; Pramod Kumar Sharma; Hanuman Singh Jatav; Satish Kumar Singh; Ashish Rai; Surya Kant; Achin Kumar
A pot experiment (Net House) study was conducted in the Department of Soil Science and Agriculture Chemistry, Institute of Agricultural Science, B.H.U. Varanasi to find out the effect of organic amendments in mustard grown in chromium (Cr)-contaminated soil during 2015–16 and 2016–17. There were five levels of Cr (Control, 20, 40, 60 and 80 mg/Kg soil) with and without three organic amendments (viz. Vermicompost (VC), FYM, and Sewage Sludge (Sl)) @ 5 t/ha, 10 t/ha and 20 t/ha, respectively. The maximum number of siliqua/plant (333 and 354), length of siliqua (5.43 and 5.53), number of seeds per siliqua (12.11 and 12.39), dry matter accumulation (50.76 and 54.65g/pot), biological yield (266.51 and 273.34g/pot), seed yield (62.63 and 66.96g/pot), stover yield (203.88 and 206.38g/pot), and harvest index (23.50 and 24.5%) were recorded when Cr-contaminated soil is treated with organic amendments mainly with vermin compost during 2015–16 and 2016–17. It is reported that significant nutrient uptake (N, P, S, K, Fe, Cu, Zn, and Mn) also increased with the application of organic amendments. It is reported that yield attributing characters are improved by the application of VC followed by farm yard manure then sewage Sl. © 2019, © 2019 Taylor & Francis Group, LLC.
