Abstract:
The experiment was conducted at Tapioca and Castor Research Station, Yethapur to evaluate the performance of chip bud plants under field conditions for assessing the vegetative growth and tuber yield parameters. The experiment was laid out in Randomized Block Design with three replications. Cassava chip budded plants were produced through Rapid Multiplication Technique (RMT) using protray method under net house and a total of ten treatments were imposed on the plating material. At the time of harvest i.e., eight months after planting, maximum plant height (141.63 cm) was recorded in chip budded plants raised in pot mixture containing Pseudomonas (T₁₀) and the minimum plant height (111.42 cm) was recorded in Mini sett plants raised in Vermicompost containing Pseudomonas. The maximum (8.6 cm) and minimum stem girth (6.8 cm) was recorded in chip budded plants raised in pot mixture containing Pseudomonas (T₁₀) and Mini sett plants raised in pot mixture containing Pseudomonas (T₉) respectively. The maximum tuber yield per plant (7.26 kg) was recorded in chip budded plants raised in Cocopeat containing Pseudomonas (T₄) which was significantly different over the other treatments. The minimum tuber yield per plant (4.58 kg) was recorded in Control (Farmers practice - Propagation by raised bed system) (T₁). The pooled mean analysis revealed that maximum starch content was recorded (25.49%) in chip budded plants raised in vermicompost containing Pseudomonas (T₇) which was on par (24.91%)with chip budded plants raised in pot mixture containing Pseudomonas (T₁₀).
