Impact of Bat Guano Otonycteris hemprichii Camd and Seaweed Extract on Some Growth and Yield Traits of Barakaseed Nigella Sativa L

Abstract

Barakaseed was improved as medicinal plant using some agricultural processes. For example, organic farmyard manure was efficiently applied to enhance growth and yield. Therefore, a field experiment was conducted out during 2012/2013 season to investigate the impact of bat guano (0, 75, 125 and 175 kg.ha^-1), seaweed extract as kelpak (0, 1, 2, 3ml.l^-1) on some growth and yield traits. Two factors were arranged in a factorial experiment system in completely randomized block design with three replicates. Results revealed that application of bat guano at 175 kg. ha^-1 was superior in enhancing plant height, fruit branch per plant, dry weight, capsules per plant, seeds per capsule, 1000 seed weight and seed yield of 66.93cm, 13.32 fruit branch. plant^-1, 44.75g. plant^-1, 14.12caps. plant^-1, 93.35seed. caps^-1, 5.64g and 943.0 kg. ha^-1 than other levels, respectively. Seaweed (kelpak) at 3 ml.l^-1 also significantly increased these traits of 61.64cm, 12.11fruit branch.plant^-1, 43.93g.plant^-1, 12.27caps.plant^-1, 82.90seed.caps^-1, 5.34g and 805.0kg.ha^-1, respectively. Moreover, the interactive combination of the highest level of bat guano with the highest level of kelpak (175Kg. ha^-1X3ml. l^-1) gave the highest seed yield of 1154.2 kg. ha^-1. It could be concluded that bat guano and kelpak efficiently improved some growth traits. Therefore, consequently increased seed yield. The improvement and increase were gradually occurred. Thus, it could be recommended to use bat guano as shifting source over to chemical fertilizer supported with foliar spraying of seaweed extract as kelpak.
