Response of bioinoculents on growth, yield and fiber quality of cotton under irrigation

Abstract

(M.S., India) to study the effect of bioinoculents on cotton. A co-cultured formulation of Azospirillum, Phosphorus solubilizing bacteria (PSB) and Pink coloured facultative methylotrops (PPFM) were used as bioinoculants in cotton var. PH-348. Plant growth parameters (length, fresh and dry weight) of shoot and root, yield parameters (weight of bolls, number of bolls per plants, seed cotton yield) and fiber quality parameters (span length, uniformity ratio, micronair value, tenacity, EIG%, SFI) were determined. Inoculation of Azospirillum, PSB and PPFMs along with chemical fertilizers resulted in to the significant increase in growth and seed cotton yield parameters of irrigated cotton. The interaction effect due to fertilizer and inoculation were significant on all dates of observations. Surat strain of Azospirillum was proved superior at all fertilizer level. The superiority of Surat strain of Azospirillum + PSB + PPFM was evident at all the fertilizer level and was immediately followed by MAU strain of Azospirillumn + PSB + PPFM. The uses of bioinoculents are beneficial in improving the fiber quality up to some extent. Keywords: Azospirillum. bioinoculants. Phosphorus solubilizing bacteria. Pink Coloured facultative methylotrops. MATERIALS AND METHODS A micro plot experiment was conducted to examine the response of bioinoculants to growth, yield and fiber quality of cotton cultivar PH-348 under irrigation at Research farm, Department of Agronomy, Marathwada Agriculture University, Parbhani (M.S. India). The experiment was laid out in a split plot design and replicated thrice. The net plot size was 3 x 3.6 m with proper irrigation channels. Well decomposed farmyard manure at the rate of 5 tones hectare-1 was applied and mixed thoroughly. Similarly, recommended dose of 100% K 2 O were applied to main plots. The following treatments were used in this study: FIELD TRIALS: Agric. Biol. J. N. Am., 2011, 2(2): 376-386 i) Main Plot: and Soil Sciences (ACSS), Marathwada Agriculture University (MAU), Parbhani (M.S., India). The bacterial suspension having a count of 10 7 c.f.u. ml-1 was added at the time of sowing just over the seed @ 2ml hill-1 .

Effect of some biofertilizers ( pgpr, biosoal and compost tea)on growth ,yield, fiber quality and yarn properties of egyptian cotton.(promising hybrid 10229xg86).

“…In addition, Patten, and Glick, and Etesami et al,(2009) explained that PGPR strains, able to augment the plants by interfering the concentration of known phytohormones that those bacteria one of the most important way affect the growth and development is by producing Indole-3 acitic acid (IAA) that led to improve root growth and development and subsequently increase uptake of nutrients. increased the yield potential and fiber properties of the Egyptian cotton .Similar results were obtained by Dhale et al,(2011) who found that the use of bioinoculents are beneficial in improving yield parameters (weight of bolls, number of bolls per plant, seed cotton yield) and fiber quality parameters (span length, uniformity ratio, micronaire value, tenacity, EIG%,)up to some extent.…”

Scoping the potential uses of beneficial microorganisms for increasing productivity in cotton cropping systems

“…in combination with NPK fertilization significantly increased cotton growth and yield in field trials under drip irrigation. Co-inoculation of fields with Azospirillum sp., P-solubilising bacteria and methylotrops significantly enhances root and shoot growth, fibre yield, and, to some extent, fibre quality when used in combination with fertilizers (Dhale et al, 2010(Dhale et al, , 2011, as well as increased yield under reduced levels of chemical fertilizers (Nalayini et al, 2010). Similarly, treatment of cottonseeds with a mixture of Pseudomonas aeruginosa Z5 and Bacillus fusiformis S10 isolated from cotton in Pakistan improved yield of cotton under reduced fertilizer conditions (Yasmin et al, 2013).…”

Response of Cotton Yield and Lint Properties to Mineral N.P.K Nano-Fertilization

“…Nano-fertilizers improve the uptake of root pores, or it could be facilitated by complication with molecular transporters or root, through the formation of new pores, or by exploitation of endocytosis or ion channels. (Dhale et al 2011). Leaf also containing nano-and micro structured surfaces, called cuticle pores and stomata.…”
