Effect of Fertility Levels and Bio-fertilizers Application on Yield, Yield Attributes, and Economics of Chickpea (Cicer arietinum L.)

The experiment was conducted during Rabi season of 2017–18 at the Students' Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh to evaluate the effect of different fertility levels and bio-fertilizers application on yield, yield attributes, and quality of late sown chickpea (Cicer arietinum L.). The experiment comprised of 12 treatment combinations in split plot design which comprised 4 treatments [F1 (control), F2 (RDF 100%), F3 (75% RDF), F4 (50% RDF)] in main plot and 3 treatments [B1 (Rhizobium + PSB), B2 (Rhizobium + PGPR) and B3 (Rhizobium + PSB + PGPR)] in sub plots with three replications. Results showed that among the different fertility levels, application of 100% RDF significantly enhanced yield and yield attributes over other treatment. Among the different bio-fertilizers treatments application of Rhizobium + PSB + PGPR had significantly improved yield attributes and seed yield as compared to Rhizobium + PGPR. The combined application of 100% RDF with Rhizobium + PSB + PGPR resulted in significantly higher seed yield of late sown chickpea during winter (Rabi). Higher values of economics viz., gross return, net return and B:C ratio in chickpea were observed with the application of 100% RDF + (Rhizobium + PSB + PGPR) treatments except cost of cultivation

Effect of glutamine supplementation and replacement of tris-egg yolk based extender with defatted cow milk on spermatozoa quality after equilibration and thawing

Abstract Aim: The present study was designed to evaluate the effect of supplementation of glutamine and replacement of Tris-egg yolk (TE) based buffer with defatted cow milk on the spermatozoa quality after equilibration and thawing. Materials and Methods: Semen was collected from five Bhadawari bulls biweekly, and a total of 30 ejaculates were taken. The semen ejaculates were pooled and divided into three equal parts. The pooled semen was diluted by TE based extender (control), TE + glutamine (8 mM) (T1) and 50% TE + 50% deffated cow milk + glutamine (8 mM) (T2). At two stages viz. after equilibration and after 12 h of cryopreservation (thawed samples), progressive motility, percent live, and percent acrosomal damage of the spermatozoa was assessed. Results: Supplementation of glutamine improved (p<0.05) the spermatozoa quality with respect to the progressive motility, percent live and acrosomal damage both post-equilibration and post-thaw. T2 improved (p<0.05) the spermatozoa quality as compared to control, however; it was less (p<0.05) effective as compared T1 both post-equilibration and post-thaw. Conclusion: From the results of present study it can be concluded that glutamine supplementation was effective in maintaining post-equilibration and post-thaw spermatozoa quality whereas defatted cow milk was not as effective as TE based buffer in the extender in improving the spermatozoa quality

University of Calgary - Zoology 435 Insect Survey Report

Students enrolled in Zoology 435 – Entomology, during fall term 2020 conducted a biodiversity survey of insects in the City of Calgary and their backyards in a variety of localities. Students collected insects where permits and permissions were available, and took digital observations for the iNaturalist platform from all localities
