Functional food corn has the potential to be developed because it has complete nutritional content. However, the nutritional value needs to be increased. One of the nutrients that needs to be improved because it is needed for plant growth and human nutritional needs is zinc. Agronomic biofortification techniques using priming and spraying leaves are believed can increase growth, production, seed quality and nutritional content in corn seeds. The aim of this research was to determine the effect of Zinc application on growth, production, seed quality and Zinc concentration levels in corn seeds. The research was arranged in a Randomized Block Design and was repeated three times and there were five treatments in this study, namely (1) control; (2) Zinc priming 0.5%; (3) Zinc priming 0.5% + spraying 0.5% Zinc 30 Days After Planting (DAP); (4) Zinc priming 0.5% + spraying 0.5% Zinc 45 DAP; (5) Zinc priming 0.5% + spraying 0.5% Zinc 50 DAP. The research results showed that the combination of seed priming and Zinc spraying had a significant effect on the variables of chlorophyll content, chlorophyll index, plant dry weight, and the number of seeds per cob of Srikandi Ungu corn variety. Zinc biofortification treatment through Zinc priming 0.5% + 0.5% Zinc spraying 50 DAP is the best treatment in increasing growth, production, seed quality and zinc content in Srikandi Ungu cord seeds compared to other treatments. Jagung pangan fungsional berpotensi untuk dikembangkan karena memiliki kandungan nutrisi yang lengkap. Namun nilai kandungan nutrisinya perlu ditingkatkan. Salah satu nutrisi yang perlu ditingkatkan kandungannya karena sangat dibutuhkan bagi pertumbuhan tanaman maupun kebutuhan nutrisi manusia adalah Zinc . Teknik biofortifikasi agronomi dengan priming dan penyemprotan daun diyakini dapat meningkatkan pertumbuhan, produksi, hingga mutu benih dan kandungan nutrisi pada benih jagung. Tujuan penelitian ini untuk mengetahui pengaruh aplikasi Zinc terhadap pertumbuhan, produksi, mutu benih, dan kadar konsentrasi Zinc dalam benih jagung. Penelitian disusun dalam Rancangan Acak Kelompok dan diulang sebanyak tiga kali. Terdapat lima perlakuan pada penelitian ini, yaitu (1) kontrol; (2) priming Zinc 0,5%; (3) priming Zinc 0,5% + penyemprotan 0,5% Zinc 30 Hari Setelah Tanam (HST); (4) priming Zinc 0,5% + penyemprotan 0,5% Zinc 45 HST; (5) priming Zinc 0,5% + penyemprotan 0,5% Zinc 50 HST. Hasil penelitian menunjukkan kombinasi priming benih serta penyemprotan Zinc berpengaruh nyata terhadap variabel kandungan klorofil, indeks klorofil, bobot kering tanaman, dan jumlah biji per tongkol jagung varietas Srikandi Ungu. Perlakuan biofortifikasi Zinc melalui priming Zinc 0,5% + penyemprotan 0.5% Zinc pada 50 HST merupakan perlakuan terbaik dalam meningkatkan pertumbuhan, produksi, mutu benih, dan kadar zinc pada benih jagung varietas Srikandi Ungu dibandingkan dengan perlakuan lainnya.

This study aimed to investigate the effects of auxin types and their concentrations on rooting of the rootstock cuttings and BA on grafting. First, IBA, NAA or IBA+NAA, each at 0, 1000, 2000, and 3000 ppm were used as treatments to study rooting of Piper colubrinum. In the second experiment, BA (0 and 50 ppm) was applied to P. nigrum scion clones of Natar-1 and Petaling-2, before being grafted to the rootstocks. Results showed, that all types of auxins (IBA, NAA or IBA+NAA) induced rooting and shoot growth, and the increase of auxin concentrations led to the increase of rooting. However, their effectiveness was different. NAA and IBA+NAA were superior to IBA, and at 2000 ppm, IBA+NAA resulted in the best plant growth, as indicated by higher values of both rooting and shoot growth parameters. Compared to control, BA treatment on scions resulted in higher grafting success (80% vs. 93%) for Natar-1, and (73% vs.100%) for Petaling-2 clones. BA treatment on scions also induced more calluses in the graft union and better shoot growth. To our knowledge, this is the first report on the use of BA to increase success of grafting between P. nigrum and P. colubrinum.

The objective of the study was to determine the effect of seed treatment on growth, seed quality, P fertilizer utilization, and rice production in the glasshouse. The experiment was conducted in a split plot design with three replications from January to June 2010.The main plots were P fertilizer rates (0, 50, and 100 kg SP-36 ha-1), and sub plots were (1) negative control (seeds were not inoculated by Xanthomonas oryzaepv. oryzae(Xoo) and without seed treatment); (2) positive control (seeds were inoculated by Xoo); (3) seeds were inoculated by Xoo and immersed in Pseudomonas diminutaA6 suspension; (4) seeds were inoculated by Xoo and immersed in Bacillus subtilis5/B suspension; (5) seeds were inoculated by Xoo and immersed in P. diminutaA6 + B. subtilis5/B suspension; (6) matriconditioning + P. diminutaA6, (7) matriconditioning + B. subtilis5/B, and (8) matriconditioning + P. diminutaA6 + B. subtilis5/B. The results showed that seed treatment with biological agents P. diminutaA6, seed treatment with P. diminutaA6 + B. subtilis5/B were the best seed treatments to improve plant growth and yield of rice. Treatment with matriconditioning + P. diminutaA6 + B. subtilis5/B was the best treatment to enhance seed germination. Soaking the seeds in B. subtilis5/B suspension or P. diminutaA6 + B. subtilis5/B suspension reduced the use of P fertilizer, based on the number of grain, total number of grain, percentage of grain per panicle. The highest seed yield obtained from both treatments was with the application of P fertilizer 50 kg ha-1. Keywords: biopriming, matriconditioning, rhizobacteria, seed viability, seed vigorABSTRAK

Bacterial leaf blight, the disease caused by Xanthomonas oryzae pv. oryzae (Xoo), a seedborne pathogen, has been known to reduce rice yield by 50%. In this study, two consecutive experiments were conducted in order to investigate the effect of various biological seed treatments applied on rice seeds artifi cially infected by Xoo on seed quality and seedling growth. Laboratory experiment was arranged in a completely randomized design while greenhouse experiment was arranged in a completely randomized block design. In both experiments, 12 seed treatments were applied: un-infected seeds (negative control) without seed treatment, Xoo infected seeds (positive control) without seed treatment, infected seeds soaked in bactericide Agrept 0.2%, infected seeds soaked in biological agent suspension isolate A6, infected seeds soaked in A54 isolate, infected seeds soaked in 5/B isolate, infected seeds soaked in 11/C isolate, infected seeds matriconditioned + A6 isolate, infected seeds matriconditioned + A54 isolate, infected seeds matriconditioned + 5/B isolate, and infected seeds matriconditioned + 11/C isolate. Soaking seeds either in Agrept 0.2% or in biological agent suspension was conducted for 30 h. Matriconditioning was conducted using ratio of seeds to carrier (burned rice hull 32 mesh) to biological agent suspension or bactericide solution of 1.0 (g) :0.8 (g): 1.2 (mL) for 30 h in air-conditioned room ca. 25 oC. Results of experiments showed that all biological seed treatments could suppress Xoo in rice seeds. Matriconditioning plus biological agent (isolate A6), biopriming with isolate A6 or isolate A54 were the best seed treatments to improve seed viability and vigor. In greenhouse experiment, matriconditioning plus isolate A54 was the best seed treatment to increase seedling growth.Keywords: biopriming, matriconditioning, rhizobacteria, seed health, viability

Upland rice is a type of rice that can be grown in Ultisol. The obstacles to cultivating plants in Ultisol are low pH and high aluminum content which hinders seed germination. Seed priming is a technology that can overcome problems with Ultisol. The aim of this research was to determine the effect of priming on the germination of upland rice seeds in acid soil conditions. The experiment conducted on non-factorial Completely Randomized Design (CRD) consisting of 8 treatments with 3 replications. The data were analyzed for variance and followed by Honest Significant Differences (HSD) at 5% using the Statistic R Program. Seed priming treatments tested were (1) Untreatment; (2) Hydropriming; (3) priming GA3 25 ppm; (4) priming GA3 50 ppm; (5) priming PEG 6000 10%; (6) priming PEG 6000 20%; (7) 0.5% KNO3 priming, and (8) 1% KNO3 priming. Rice seed are soaked in priming for 24 hours. The upland rice seeds of the Inpago 13 Fortiz variety were planted in Ultisol soil media with a pH of 4.45, Al content of 0.44%, and Fe 1.37%. The results showed that the priming treatment increased the germination and themost effective treatment was priming GA3 50 ppm, each value of showed germination (92.38%), germination speed (19.71% day-1), vigor index (83.81%), and time of appearance of plumule (2.96 day).
