Description An experiment on the “Effect of Time, Etiolation and IBA concentration on Rooting of Semi hard wood cuttings of Tamarind (Tamarindus indica L.)” was carried out at College Farm, Horticultural College and Research Institute, Venkataramannagudem, West Godavari District during period from June to October, 2013 with an objective of finding out the best month and IBA concentration among the etiolated and non-etiolated cuttings. The rooting and shooting parameters were significantly influenced by month, etiolation, IBA concentration as well as their interactions at 60 days after planting the cuttings. Percentage of rooted cuttings, length of longest root, fresh weight of roots and dry weight of roots were found to be at maximum in those cuttings planted in June and received the treatments of etiolation and IBA dip @ 1000 ppm. Similar trend was observed in case of shooting also in terms of number of shoots per cutting, number of leaves per cutting, fresh and dry weight of shoots.
The cuttings planted in the month of June were found to record maximum survival percentage of rooted cutting followed by August whereas, the minimum percentage of rooting was observed in October month. The cuttings treated with etiolation showing best survival percentage of rooting compared to those without etiolation and treatment. Similarly cuttings treated with IBA at 1000 ppm recorded the highest survival percentage as compared to those treated by IBA at 2000 ppm. The cuttings planted in the month of June have recorded maximum percentage of establishment of rooted cuttings. The cuttings planted in the month of June have recorded the minimum value of C:N ratio at the end of rooting experiment. Analysis of carbohydrate utility and increase in protein content were also in favour of June planted etiolated and IBA (1000 ppm) treated cuttings as compared to other treatment combinations.
Such appreciable performance of June planted cuttings was attributed to the fact that the congenial climatic conditions. The superiority of etiolation was attributed to the anatomical and biochemical reasons in that the etiolated region might had high endogenous auxins, which might act synergistically with exogenous plant growth substances to facilitate easy rooting.
