Abstract: Coriander (Coriandrum sativum L.) is an important seed spice crop of family Apiaceae (Umbelliferae). Seed is an important component and a quality seed plays a crucial role in agricultural production as well as in national economy. Availability of viable and vigorous seed at the planting time is important for achieving targets of agricultural production because good quality seed acts as a catalyst for realizing the potential of other inputs. Since the total cultivable area is decreasing due to over growing population, the increased agricultural productivity is the only option. The good quality seed is pre-requisite to enhance the production and productivity. Plant growth regulators have emerged as chemical that could increase agricultural production at an unprecedented rate and help in removing or circumventing many of the barrier imposed by genetics and environment. Therefore considering the significance of coriander in national economy, a field experiment entitled “Influence of Plant Growth Regulators on Leat, Seed yield and Quality of Coriander (Coriandrum sativum L.) var. Shalimar Dhania-1†was conducted at experimental field of Division of Vegetable Science Sher-e-Kashmir University of Agricultural Sciences and Technology Shalimar during Rabi 2017-2018. The experiment consisted of 6 levels of plant growth regulators Gibberlic acid (GA3), 1- Naphthalenacetic acid (NAA) and 2, 4-Dichlorophenoxyacetic acid (2, 4-D) each at different concentrations, applied at three stages (soaking of seeds, foliar application at 4-6 leaf stage and at initiation of flowering). An absolute control was also maintained. Thus, experiment consisted of 21 treatment combinations.
The results indicated that application of treatment, (T2) GA3 45 ppm resulted in maximum values for growth parameters viz., plant height (cm), number of nodes on main shoot, fresh weight of leaves per plant (g), number of branches per plant, number of green leaves per plant, fresh weight of shoots per plant (g), plant spread (cm), and minimum days taken for 50 percent flowering. Similarly maximum values for yield and yield attributing parameters viz., leaf yield per plot (kg), number of umbels per plant, seed yield per plant (g), seed yield per plot (kg) were recorded by treatment, T2 (GA3 45 ppm).
