Abstract Ebony ( Diospyros celebica Bakh.) is a slow-growing species that an impacting factor in the extinction of this species. Efforts to reduce ebony population can be performed by employing microbes stimulate growth. This study aimed obtain bacterial isolates with potential producing IAA and GA3 further utilized as biofertilizer agents. Research stages encompassed soil sample isolation, iso...

Two 28-d randomized complete block design experiments were conducted to evaluate the effects of concentrations and sources of Zn on growth performance of nursery pigs. Seven stations participated in Exp. 1, which evaluated the efficacy of replacing 2,500 ppm of Zn from ZnO with 125, 250, or 500 ppm of Zn from Zn methionine. A control diet with 125 ppm of supplemental Zn was included at all stat...

Six compounds (IBA, chlorogenic acid, cytokinine, GA3, alar B-9 and maleic hydrazide) belonging to four different categories of plant growth hormones were used to study their effect on carbohydrate content in L. erysimi. The second instar nymphs (48 hr old) were given both dipping and leaf surface treatment with 1024 ppm concentration of compounds for two time intervals i.e. 48 and 96 hr. The c...

Samples of the waste rock obtained from Marofengin South Africa ground 60, 70 and 80% passing 75µm were leached with cyanide in bottle roll tests. The results obtained showed that the percentage gold dissolution depends more on the ore size consists than on the cyanide concentration with the highest average dissolution rates of 88.75, 94.34 and 95.90% found at 600, 500 and 500 ppm, for 60, ...

Effect of growth hormones i.e., gibberellic acid (GA3), indole-3-acetic acid (IAA) and Kinetin was studied on the root of Cicer arietinum L. after forty-five and sixty days of treatments and compared with control. The application of GA3 alone and in combination with IAA or Kinetin or both caused extension growth and insignificant increase in the number of rootlets accompanied with decrease in t...
