Abstract
An exploratory study entitled “Performance study of rooted cuttings of spine gourd (Momordica dioica Roxb.) during winter months under the coastal zone of Odisha as influenced by plant growth regulators” was conducted during September to February (2015-16) at the College of Agriculture, OUAT, Bhubaneswar, to assess the performance of rooted cuttings of spine gourd during the winter months under the coastal zone of Odisha and the impact of different growth regulators on it. The study comprised of local type of spine gourd, nine growth regulators (different types and concentrations) treatments and one control. The growth regulators comprised of IAA (50,100,250 and 500ppm), GA3 (10,20 and 50 ppm) and NAA (50 and 100 ppm). The experiment was replicated thrice and was laid out in randomized block design. The rooted cuttings of spine gourd were planted on 27th September and the growth regulators are applied as per schedule i.e. IAA treatments were done 10 DAT and GA3 & NAA were sprayed 20 DAT. The growth and yield attributing characters were studied along with the quality parameters. From the study it was observed that all the treatments produced fruits during winter, which in itself is a new accomplishment for the farming community of the coastal zone who can get good returns from this minor crop. Further GA3 @ 50 ppm and NAA @ 100 ppm showed further excellence by enhancing the growth and yield attributes. NAA @ 100 ppm further, recorded highest TSS of fruits. Although both the treatments GA3 @50 ppm and NAA @ 100 ppm were at par but looking into the economics NAA@ 100 ppm excelled GA3 giving higher additional return per additional rupee invested. However, this experiment may be repeated this year i.e. during September 2016- February 2017 to get the confirm results for recommending to the farmers.
