Influence of Bio-fertilizer and Organic Seed Treatment on Growth and Yield Attributing Traits of Mustard (Brassica nigra L.) Variety (Pusa -21)

Abstract

The Field experiment was conducted in a Randomized block Design (RBD) with three replications during Rabi, 2020-2021 at Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj. The genetically pure seeds of Mustard variety Pusa-21 were used for the study. The mustard seeds primed with botanicals and chemicals( Vermiwash, Panchagavya, Azatobactor, NaCl , KNO3, Neem leaf, Parthenium leaf and FYM) were subjected to  study in field experiment of growth and yield parameters were recorded. Objectives of the topic are to evaluate the Influence of bio fertilizer and organic seed treatment on growth, yield and yield attributing traits of mustard crop and to find out the suitable pre-sowing seed treatment  for mustard crop. Analysis of variance revealed significant mean sum of squares due to seed priming treatments. The highest germination percent (88.89),plant height (132.53 cm), number of branches(12.60 per plant),  yield attributing parameters in mustard as number of silique per plant (292.87), number of seeds per silique (18.73), seed yield per plant (17.73 gm/plant), seed yield  per plot (214.33 gm/ plot), biological yield per plot (443.15/ plot), seed yield per hectare (2143.33 kg/ ha), biological yield per hectare (5140 kg/ ha) and harvest index (41.69) showing better result when treated with treatment vermiwash 5 % for 12 hours. Remaining treatments i.e, treatment with panchgavya 5 % & 3 %, azotobactor 3 % & 2 %, NaCl  0.5 % & 0.1 %, KNO3 0.5 % & 0.1 %, neem leaf extract, parthenium leaf extract for and fym 2 % for 12 hours recorded the second most effective treatments and observed significantly superior. It  concluded that T8 (vermiwash 5% solution) found superior in all the growth and yield parameters.
