Abstract

The impact of chemical fertilizers, organic manure and bio-enhancer focuses at efficient and judicious use of the main sources of plant nutrients. It is done in a balance manner so as to get maximum economic yield without any deleterious effect which is affecting the physical, chemical and biological properties of the soil. Only some experimental studies have been done in onion for chemical fertilizers, organic manure and bio-enhancer. With this background an experiment was conducted at the agriculture farm (Rajaula) of Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) during 2019. The experiment was laid out in Randomized Block Design (RBD) having fourteen treatments replicated thrice. As per the findings, significantly higher bulb diameter (6.10 cm), bulb length (6.37 cm), bulb weight (60.63), bulb ring (7.33), yield ha-1 (24.50 q) was recorded with treatment T11-(25% N equivalent from organic source + 75% RDF (NPK 75:60:60 kg ha-1) + Bio-fertilizer consortium (Azotobacter + PSB) and Bio-enhancer Seedling treatment (panchgavya) spray at 15 days interval from 20 days), which was at par with application of T2 (R.D.F. NPK 100:80:80 kg ha-1). Maximum plant height 90 DAS (65.93 cm), Number of leaves 90 DAS (7.20) and leaves length 90 DAS (53.50 cm) was recorded with application of T2 (R.D.F. NPK 100:80:80 kg ha-1) which was followed by application of T11-(25% N equivalent from organic source + 75% RDF (NPK 75:60:60 kg ha-1) + Bio-fertilizer consortium (Azotobacter + PSB) and Bio-enhancer Seedling treatment (panchgavya) spray at 15 days interval from 20 days). The results showed that application of T11-(25% N equivalent from organic source + 75% RDF (NPK 75:60:60 kg ha-1) + Bio-fertilizer consortium (Azotobacter + PSB) and Bio-enhancer Seedling treatment (panchgavya) spray at 15 days interval from 20 days), this treatment proved to be promising for the enhancement the yield of onion under the Bundelkhand Agro-climatic condition.

Conclusion

In view of experimental result obtained during the present investigation, treatment T11- 25% N equivalent from organic manures source + 75% RDF (NPK 75:60:60 kg ha-1) + Bio fertilizers consortium (Azotobacter + PSB) and Bio-enhancer Seedling treatment (Panchgavya) spray at 15 days interval from 20 days, emerged as superior over all other treatments, in relation to yield attributes of onion under the Bundelkhand Agro-climate condition.
