Abstract

This study aimed to determine the best level of phosphate basic fertilization for seed production of Hulaliu corn varieties with high viability and vigor.  This study was conducted in two places, namely in Booi Village, Saparua Subdistrict, Central Maluku District, for experiment with phosphate fertilization treatment, and in the Laboratory of Balai Besar Perbenihan dan Proteksi Tanaman Perkebunan Maluku in Passo, Baguala Subdistrict, Ambon, for testing seed viability and vigor.  The experimental design used was a single factor Randomized Block Design with five levels of phosphate fertilization, consisting of  P1 = 50 kg P2O5 per ha; P2 = 55 kg P2O5 per ha;. P3 = 60 kg P2O5 per ha; P4 = 65 kg P2O5 per ha, P5 = 70 kg P2O5 per ha = 70 kg, and with three replications.  The results showed that the optimal levels of phosphate fertilization to enhance seed viability and vigor of Hulaliu local corn varieties were between 55 to 70 kg P2O5 per ha.

Abstract

This study was aimed to determine the proper dose of ash desiccant on maize seed stored for 30, 60 and 90 days. The design used was a Completely Randomized Factorial Design, with two factors and three replications.  The first factor was desiccant dose (D) : Do = 0 % (control), D1 = 5 % (12.5 g of seed weight), D2 = 10% (25 g of seed weight), D3 = 15 % (37 g of seed weight), D4 = 20 % (50 %g of seed weight), D5 = 25 % (62.5 g of seed weight).  The second factor was length of storage (S) : S1 = 30 day storage, S2 = 60 day storage and S3 = 90 day storage. The result show that use of desiccant only gave effect on the water content of seeds (12.31 %) and speed of seed growth vigor parameters (24.84 %).  Use of desiccant in 90 day storage were able to maintain water content of seeds (12.43 %), seed germination viability parameter (100 %), and vigor of seeds, which consisted of seed growth simultaneity (66.77 %) and seed growth speed (28.71 %).  The interaction between the use off ash desiccant and the length of storage had no effect on  viability and vigor of maize (Zea mays L) seeds but had an effect on their water content after storage (12.73%).
