Abstract
A field experiment entitled “Effect of different doses of bio-stimulants on growth and development of guava (Psidium guajava L.) cv. sardar‟‟ was conducted during the year 2020-21, at the Instructional Farm, Department of Fruit Science, College of Horticulture and Forestry, Jhalawar. The experiment consisted of 19 treatments laid out in Randomized Block Design with three replications.Among different bio-stimulants treatments, T12 humic acid 15g + seaweed 60g was found significantly superior over all other treatments with respect to most of the plant growth and development parametres besides better soil physicochemical and biological properties. The plant growth characters viz. plant height (53.32%), canopy spread E-W (48.59%), canopy spread N-S (68.98%), rootstock girth (19.81%), scion girth (19.60%), number of leaves/plant (75.87%), number of shoots/plant (81.54%), length of internodes (71.768 %), number of nodes/branch (47.89%), number of leaves/shoot (31.01%), and number of shoots/branch (35.63%), leaf length (30.95%), leaf width (39.26%), leaf area (61.43%), length of internodes (71.77%), proline content in leaf (4.95%), relative water content (97.57%) and leaf N, P, K content (2.99%), (0.33%), (1.99%).
The T12 treatment was found better in improving the soil parameters including organic carbon percentage, available N, P and K content of soil and was found significantly superior over other treatments. Like-wise, soil pH and electrical conductivity also had significant moderation under this treatment. The treatment T11 (Humic acid 15g + Seaweed 50g) was in next order in its impact on vegetative growth and developmental parameters of guava plant besides better soil parameters of the orchard under the study.
