Abstract
The field investigation was carried out during October 2019 – February 2020 at Achalvadi village, Harur block in Dharmapuri district to study the effect of VAM, sulphur and boron on chlorophyll content, root characters, yield and economics of ragi. The present investigation consisted of eleven treatments and three replications and the experimental plots were laid out in randomized block design. The treatments of the investigation are T1 - RDF alone (60:30:30 Kg of NPK ha-1) / control, T2 - T1 + Farm yard manure @ 12.5 t ha-1, T3 - T1+ Vermicompost @ 3 t ha-1, T4 - T2 + Seed treatment with Azospirillum @ 600 g ha-1, T5 - T3 + Seed treatment with Azospirillum @ 600 g ha-1, T6 - T4 + Inoculation of VAM @ 12 kg ha-1, T7 - T5 + Inoculation of VAM @ 12 kg ha-1, T8 - T6 + Sulphur @ 40 kg ha-1 through gypsum, T9 - T7 + Sulphur @ 40 kg ha-1 through gypsum, T10 - T8 + Foliar spray of Borax 0.5% twice at 30 DAT and 45 DAT and T11 - T9 + Foliar spray of Borax 0.5% twice at 30 and 45 DAT. The results of the present investigation revealed that application of RDF (60:30:30 kgs of NPK ha-1) + Vermicompost @ 3 t ha-1 + Seed treatment with Azospirillum @ 600 g ha-1 + Inoculation of VAM @ 12 kg ha-1 + Sulphur @ 40 kg ha-1 through gypsum + Foliar spray of Borax 0.5% twice at 30 and 45 DAT (T11) predominantly influenced the chlorophyll content, root characters, grain and straw yield and economics of ragi. This treatment has produced the higher chlorophyll content index (6.96 and 8.98 at 30 and 60 DAT respectively), root characters viz., root length (15.90 cm), root volume (36.33 cc), grain and straw yield (2963.60 and 5414.43 kg ha-1 respectively). The same treatment has recorded the highest mycorrhizal root colonization percentage (39.66) and it was on par with the other mycorrhizal inoculated treatments. With regard to the economics of ragi, application of RDF (60:30:30 kgs of NPK ha-1) + Farm yard manure @ 12 t ha-1 + Seed treatment with Azospirillum @ 600 g ha-1 + Inoculation of VAM @ 12 kg ha-1 + Sulphur @ 40 kg ha-1 through gypsum + Foliar spray of Borax 0.5% twice at 30 and 45 DAT (T10) has recorded the higher values of net income (Rs. 51810.54) and return rupee-1 investment (2.13) of ragi.
