“…A. brasilense is known for the ability to alter the architecture of the roots of plants, increasing the formation of lateral and adventitious roots and root hairs. This is because of the production or metabolization by A. brasilense of chemical signaling compounds that alter root elongation and arrangement and the formation of root hairs [26].…”

Association between auxins and plant growth-promoting bacteria can stimulate root growth and development of fruit crop nursery plants, and can be a promising biological alternative to increase the rooting of cuttings. The objective of this study was to assess the viability of producing ‘Powderblue’ blueberry nursery plants from cuttings using different doses of indolebutyric acid (IBA) in association with Azospirillum brasilense. The following treatments were tested: 0 (control); 500 mg L−1 of IBA; 1000 mg L−1 of IBA; A. brasilense; 500 mg L−1 of IBA + A. brasilense; and 1000 mg L−1 of IBA + A. brasilense. The experimental design was completely randomized, with six treatments and four replicates, and each plot (box) consisted of 10 cuttings. The boxes were arranged in a mist chamber with an intermittent regimen controlled by a timer and solenoid valve. After 90 days, the following variables were assessed: rooted cuttings; survival of cuttings; foliar retention; sprouting; cuttings with callus; root dry mass per cutting; number of roots per cutting; and root length. It was observed that the application of IBA with the A. brasilense rhizobacteria increased the number of roots of ‘Powderblue’ blueberry cuttings, while the treatments with IBA alone and IBA 1000 mg L−1 + A. brasilense increased the root length of cuttings. However, treatments with IBA and A. brasilense had no impact on % rooted cuttings and % survival of cuttings.

“…The presence growth promoting substances due to colonization of Arbuscular mycorrhiza promoted plant growth and could have increased the chlorophyll production by boosting the photosynthetic process and stimulating vegetative growth. Thus, an overall plant performance would have enhanced accordingly and finally reflecting through increased production of haulm (Gouda et al 2018).…”

Background: Irrigation and proper nutrient management that determines the productivity of the groundnut especially during the critical stages of the crop growth. Methods: The experiments laid out in split plot design comprising of three levels of irrigation scheduling [0.8 IW/CPE ratio (I1), 0.6 IW/CPE ratio (I2) and 0.4 IW/CPE ratio (I3)] in main plots and four nutrient management practices viz., N1- 75% of RDF with 5 t of charred rice husk, N2 - 50% of RDF with 5 t of charred rice husk, N3 - 75% of RDF with 5 t of charred rice husk along with seed treatment of Abuscular mycorrhiza and N4 - 50% of RDF with 5 t of charred rice husk along with seed treatment Arbuscular mycorrhiza in sub plots and replicated thrice. Result: Highest pod yield (2003, 2099 and 2063 kg ha-1 during summer, kharif and rabi 2017, respectively) of groundnut was registered with irrigation scheduling at 0.8 IW/CPE ratio along with 75% of RDF and 5 t of charred rice husk as basal with seed treatment of Arbuscular mycorrhiza. The maximum water use efficiency was also recorded under of the same treatment (4.16, 7.07 and 4.86 kg ha-1 mm-1 during the various seasons respectively). The highest B:C ratio of 2.2, 2.4 and 2.2 was recorded during summer, kharif and rabi 2017, respectively were also registered with same combination irrigation and nutrient management.

Thus, an overall plant performance would have enhanced accordingly and finally reflecting through increased production of haulm (Gouda et al, 2018). Moreover, basal application of soil amendment of charred rice husk along with seed treatment of arbuscular mycorrhiza might have had a positive effect on the soil physical properties such as bulk density and pore space, which could have increased the water retention capacity.…”

Background: Different levels of nutrient management practice and soil amendments charred rice husk with Arbuscular mycorrhizae during the critical stages of the crop growth enhances the productivity of the groundnut crop. Methods: The field experiments were conducted summer, kharif and rabi seasons of 2016-17 and 2017-2018 at AC and RI, TNAU, Madurai. The main plots consisted of three levels of irrigation scheduling viz., I1- 0.8 IW/CPE, I2- 0.6 IW/CPE and I3- 0.6 IW/CPE ratio and sub plot comprised of four level of nutrient management practices viz., N1-75% of recommended dose of fertilizer with 5t of charred rice husk, N2- 50% of recommended dose of fertilizer with 5t of charred rice husk, N3-75% of recommended dose of fertilizer with 5t of charred rice husk along with seed treatment of Arbuscular mycorrhiza and N4- 50% of recommended dose of fertilizer with 5t of charred rice husk along with seed treatment Arbuscular mycorrhiza. Result: The study revealed that the highest plant height, dry matter production, leaf area index, leaf single photon avalanche diode value, pod yield and haulm yield, nutrient uptake (N,P,K) of groundnut crop and soil enzyme activities in soil was registered with the application of 75% recommended dose of fertilizer and 5t of charred rice husk as basal with seed treatment of Arbuscular mycorrhiza. The highest pod and haulm yield of 1783, 1935 and 1854 kg ha-1 and 4743, 4272 and 4338 kg ha-1 during summer, kharif and rabi’ 2017 seasons respectively of groundnut was registered with 75% of recommended dose of fertilizer and 5t of charred rice husk as basal with seed treatment of Arbuscular mycorrhiza.
