Abstract

ABSTRACT Research has been implemented as of July 2012, in the  BPSB Laboratory  of North Sulawesi Province i.e.: 1) to test the seed lacking in vigour during the Random Complete Design with three treatments of the various harvest ages, i.e. U1 (90 dasy), U2 (100 days) and U3 (110 days) treatments repeated four times; 2) in the greenhouse to see the amount of the normal, sprouts abnormal, seeds, hard seed and dead, shoot root ratio by using the Random Completed Design with two factors, respectively are : factorial in complete factors of the first different age harvest U1 (90 days), U2 (100 days) and U3 (110 days), the second factor granting of the water with different capacity P1 (3600 ml), P2 (2700 ml), P3 (1800 ml) and P4 (900 ml). Data analysis were found by the various analysis, however if there are different results, it would continue on the Smallest Significant Test. The results showed that, Electric Power Conductivity (EPC) affected by the age of harvest seed corn. The highest EPC at the harvest ages of 90 days and the lowest at 100 days and 110 days. It would be shown that the great value of EPC, the smallest amount of germination. There is no interaction between the age of abnormal seeds, hard seed die, shoot root ratio and high sprouts, but single factor treatment of harvest age and media planting humidity were significantly effected toward sprout normal, abnormal seed, hard seed die, shoot root ratio and high sprouts. Keywords : corn seed, harvest ages, humidity ABSTRAK   Penelitian dilaksanakan sejak bulan Juli 2012, penelitian pertama di Laboratorium Balai Penelitian dan Sertifikasi Benih (BPSB) Provinsi Sulawesi Utara, untuk menguji vigor benih menggunakan Rancangan Acak Lengkap dengan tiga perlakuan umur panen yang berbeda: U1 (90 Hari), U2 (100 Hari) dan U3 (110 hari) perlakuan diulang empat kali.

Abstract

ABSTRACT   The objective of this research was to evaluate the vegetative development in 3 North Sulawesi local rice varieties (Superwin (A), Temo (B) dan Burungan (C)) as a response to the thickness variation of cultivated soil layer combined with irrigation deletion. This research was conducted in the glasshouse using polyvinyl chloride (PVC) column (500 mm height, 125 mm diameter) as pots. The treatments consisted of 3 variations of cultivated soil layer, i.e. 18, 24 and 30 cm and the clay hardpan was placed below each of the cultivated soil layers. The level of irrigated water and the amount of the fertilizer were applied following the method of SRI (System of Rice Intensification). The results showed that reducing the thickness of cultivated soil layer to 18-24 cm saved the water as much as 6.15-8.12 L (29.7-39.2%) per pot compared with 30 cm thickness of soil layer in Burungan. Comparing with the 24 cm soil layer thickness, the treatments of 18 cm thickness saved 6.92 L (23.42%) and 5.77 L (18.32%) water, respectively in Superwin and Temo.
