تأثير البوتاسيوم وحامض الجبرليك في بعض صفات ومكونات الحاصل لنبات الحبة السوداء (Nigella sativa L.)

Abstract

The experiment carried out by using plastic pots in uncovered the plastic house dependent to the department of Science_the Basic Education College / AL Mustansiriya university / to growing season 2014- 2015. And that to find out effect of potassium and Gibberellic acid in some recipes growth yield and components Plant (Nigella sativa L.) from the active compounds. Experience has been performed according to completely Randomized Design(CRD) As an global experiment by three repeaters for each transaction , and use test less significant difference (LSD) at level of probability 0.05 to comparison averages of transactions. The Nigella sativa L. seeds has been planted on 2/11/2014 as four levels used from potassium its (0, 100, 200, 300) Kgm.h-1 add four concentration from Gibberellic asid to soil its (0, 25, 50, 100) mg.ltr -1 spray on plants potassium has been the main factor and Gibberellic acid the second factor it was a global experience (4x4x3) include 48 unit training(pot)and capacity all pot (10)kg from soil and diameter (20cm) Soil has been taken after softening and Sieved by sieve capacity of all opening (2mm) follow up experiment.Potassium added in level (300) Kgm.h-1 to increase at number of flower 48%, number of cans 59.22% ,number of seeds in the capsules 12% ,weight 1000 grain 28% and increase yield seeds 132% compared with the control treatment.The Gibberellic acid spry at concentrations (100) mg.ltr -1 to increase at number of the flower 17%, number of seeds in capsules 6%, weight 1000 grain 9% and yield seeds 39% compared with the control treatment.The overlap between potassium and Gibberellic acid given significant increase in yield seeds. Where the overlap between level (300)Kgm.h-1 from potassium and concentration (100)mg.ltr -1 from Gibberellic acid to increase by 247% compared with the control treatment.Key words: Nigella sativa L., potassium, Gibberellic acid
