Full text linkThis research was aimed to know the effect in various of gibberellic acid (GA3) concentration and kind of growth plant to germination of tamarind seed (Tamarindus indica L.). This research was conducted in Green House of Faculty of Agriculture University of Sultan Ageng Tirtayasa Serang Banten from October until November 2016. The research used a Randomized Completely Design arranged as factorial and consisted of two factors. The first factor was the concentration of Gibberellic Acid (GA3), consisted of three levels were G0 (without GA3), G1 (concentration of 500 ppm) and G2 (concentration 750 ppm). The second factor was kind of growth plant, consisted of four levels were M1 (ground), M2 (sand), M3 (husk), and M4 (soil+sand 1:1 (v/v)). The treatment combination was repeated 3 replicates. Parameters measured were day of germination, power of germination, maximum growth potential, growth rate, normal sprout, and abnormal sprout. The results showed that immersion without GA3 tend to gave better effect to the parameters of maximum growth potential (100%), normal sprout (99.6%), power of germination (70.8%), and the speed of growth (6.2%) than the immersion with the provision of GA3. Treatment kind of growth plant that M3 (husk) tended better effect to day of germination (7.5 days), power of germination (72.2%) and abnormal sprout (0.11%). There was no interaction between the concentrations of GA3 and the growth plant for all parameters observed. Keywords: Germination, Gibberelic acid, Growth plant, Tamarin
KAJIAN FISIOLOGIS TANAMAN TOMAT TERHADAP PENAMBAHAN UNSUR HARA Fe DAN N
Full text linkNitrogen is the most dominant element affecting plant growth compared to other elements. Whereas Fe is rare. The occurrence of symptoms in parts of the plant (especially leaves) is then expressed as a lack of Fe availability because of the imbalance in the Fe availability with Calcium in the soil which is excessive on Calsium and alkaline. The purpose of this research was to knowing the symptoms of agility and poisoning of macro and micro-nutritional elements on physiological properties and growth of tomato plants. The research had been conductedin January - March 2017 at Green House and Laboratory of Agriculture of STIPER Petra Baliem Wamena, Papua. The treatments were assigned in Completely Randomized Design with addition of N and Fe i.e. without Fe (-Fe), 3x Fe (3Fe), 3x N, treatment of N + Fe (complete) and without N (-N), then followed by Duncan's multiple ranges test at level 0.5. The results showed the treatment of 3xN and 3xFe of the Hoagland dose 2 solution had not reached the maximum level so that it had not shown any toxic symptoms, symptoms of N deficiency were chlorosis (pale green to yellow) in old leaves, stunted growth, and more leaf necrosis bottom in cases of severe N deficiency, and 3xFe treatment of Hoagland 2 doses resulted in the lowest plant height estimated due to iron toxicity.
