ABSTRACT This research aims to 1) Study the growth and yield responses of purple corn location effect of the seed source on the ear to growth and yield of, 2) Determine the right location of the seed source on the ear to get the best of growth and yield of purple corn. Research conducted at the Kebun Percobaan (KP) Pandu, Faculty of Agriculture, University of Sam Ratulangi (Unsrat) Manado from April to July 2016. The plant material used is purple corn collected in the laboratory of Plant Science, Faculty of Agriculture, Unsrat. This research is using a randomized block design by four treatments, such as: L1 (base of the ear), L2 (center of the ear), L3 (tip of the ear), and L4 (all parts of the ear). Each treatment consisted of four replicates so that there are 16 experimental units. The results showed that treatment of the seed source location on the ear gives no significant effect on all components of growth. The treatment of L4 (base of the ear) produces the highest percentage of plants grown for 14 days after planting (42.75%), treatment of L2 (center of the ear) produces highest of the plant height at 20 and 40 days after planting (6.17 cm and 45.68 cm). On purple corn yield components, the treatment provides a significant effect on the weight of ear and length of the ear, but no significant effect on the diameter of the ear, number of seed rows per ear and weight of 100 seeds. Treatment L2 (center of the ear) produces the highest yields on the weight of the ear (36.90 g), length of the ear (10.49 cm), diameter of the ear (2.92 cm), the number of seed rows per ear (7.55 lines) and weight of 100 seeds (24.56 g).

Abstract

ABSTRACT   The research was aimed to determine the parent genotypes of purple corn by the similarity of expected ratio on kernels S1 and S2 using four locus models, Pr/pr, C/c, R/r and Y/y genes. The study was conducted in two phases, namely, 1) Making the individuals of selfing to-1 (S1), and 2) Making the individuals of selfing to-2 (S2). Observed data in the form of kernel per ear of corn was separated by the characters of purple, yellow and white color then analyzed by using the Chi-square Test. The results showed that the offspring genotype from selfing on the base population can be predicted by looking at the suitability between the offspring and parental genotypes based on the ratio of expectation. Parent genotypes prediction on the base population of selfing were PrPrCcRrYy, PrPrCcRryy, PrPrCcRrYY, PrPrCcRRYY and PrPrCCRrYY. Keywords: parent genotypes, purple kernel, corn ABSTRAK Tujuan penelitian ini adalah mengetahui genotipe tetua jagung berbulir ungu berdasarkan kesesuaian dengan nisbah harapan pada bulir S1 dan S2 menggunakan model empat lokus yaitu gen Pr/pr, C/c, R/r dan Y/y.

Abstract

Spinach (Amaranthus sp) is a plant belonging to the Amaranthaceae family. Spinach is one of the oldest food plants in the world originating from America, which has been cultivated around 6700 years BC and is now spread throughout tropical and subtropical areas throughout the world. Copra fumigation ash contains macro and micro nutrients that plants need, one of which is potassium. This research aims to determine the effect of copra fumigation ash on the growth of spinach plants. This research was carried out at the Green House, Faculty of Agriculture, Sam Ratulangi University, Manado, North Sulawesi from June to July 2024. This research used a Randomized Group Design (RAK) with six treatments and four replications consisting of Without Ash Copra Fumigation (K0), 5 tons Copra Fumigation Ash/ha (K1), 10 tonnes of Copra Fumigation Ash/ha (K2), 15 tonnes of Copra Fumigation Ash/ha (K3), 20 tonnes of Copra Fumigation Ash/ha (K4) and 25 tonnes of Copra Fumigation Ash/ha ( K5). The research data were analyzed using the F test using the Microsoft Office Excel program to determine the effect of copra fumigation ash treatment on the growth of spinach plants. The research results showed that copra fumigation ash had a significant effect on the variable height of spinach plants but not on the number of leaves and width of spinach leaves. Copra fumigation ash also has a very significant effect on the fresh weight of spinach plants. It is recommended to use copra ash at a dose of 20 tons/ha as the recommended dose for spinach cultivation activities.
