Abstract

ABSTRACT This research aims to study 1) Maternal effect on the inheritance of yield components of Manado Yellow Corn, and 2) Inheritance of seed colour and seed type of Manado Yellow Corn. Research conducted in Kalasey village, Mandolang subdistrict, Minahasa regency, Province of North Sulawesi from April to September 2016. The plant material used is a local variety of Manado Yellow Corn that collectedin the laboratory of Plant Science, Faculty of Agriculture, University of Sam Ratulangi, Manado. This research was arranged to compare two hybridization treatments, from two parent population, that is: 1) Local corn with yellow seed colour and flint seed type, 2) Local corn with yellow seed colour and dent seed type. Each treatment consisted of four replicates and each of replicating consisted of six female plants so that there were 24 ears from parents hybridization and (F1) and 24 ears of reciprocal hybridization (F1R). The results showed that 1) There was not maternal effect on the inheritance of yield components, such as the weight of the ear, length of the ear, the diameter of the ear, number of seed row per ear, number of yellow seed color and number of dent seed type with crossed the parent of Manado Yellow corn, 2) There was maternal effect on inheritance of flint seed type with crossed the parent of Manado Yellow corn and 3) The highest percentage of yellow seed color and flint seed type, the character of Manado Yellow Corn, obtained from crossing parents ♀ Flint × ♂ Dent.Keywords: dent, flint, anado yellow corn

Abstract

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). Keywords: corn, seed source location of corn, purple corn

Abstract

Lead (Pb) is a highly toxic heavy metal that can have a negative influence on chlorophyll because most of it is accumulated by plant organs, namely leaves, stems, and roots, as well as soil around plants. This study aims to examine the Pb content in the leaves of Angsana (P1), Trembesi (P2), and Mahoni plants in the urban green spaces around UNSRAT (T1), KONI (T2) and Sparta Tikala Sport Field (T3) in Manado. Pb content testing uses the AAS (Atomic Absorption Spectrophotometery) method in the laboratory of Manado Industrial Standards Agency. This research was compiled using a Randomized Block Design (RCBD) with 2 treatment factors, namely tree species (P) and sampling locations (T). Each treatment was repeated 3 times to obtain 27 experimental units. The results showed that the treatment of tree species and sampling locations had a significant influence on lead sorption by leaves. Interaction of P3T3 treatment produced the highest lead sorption at 1.14 ppm, which was not significantly different from P3T1 (1.12 ppm), P3T2 (1.07 ppm), P2T2 (1.01 ppm), P2T3 (0.97 ppm), P2T1 (0.97 ppm), P1T3 (0.92 ppm) but significantly different from P1T2 (0.89 ppm) and P1T1 (0.87 ppm).  Overall, the results of Pb sorption are within the normal limits of Pb content in plants ranging from 0.5 to 3.0 ppm.

Abstract

With an agroecological philosophy, the SRI (System of Rice Intensification) technique is a rice production technology approach that prioritizes soil, plant, and water management through local expertise and group empowerment based on environmentally beneficial activities. The purpose of this study is to investigate lowland rice growth and yield by using composted straw instead of NPK fertilizer. Implemented in Tara-Tara II village, West Tomohon sub-district for 5 (five) months with one factor treatment, namely the ratio of NPK fertilizer dose and straw compost dose: 100% NPK + straw compost 0% straw compost (P0), 75% NPK + 25% straw compost (P1), 50% NPK + 50% straw compost (P2), 25% NPK + 75% straw compost (P3), and 0% NPK + 100% straw compost (P4). The variables observed included: plant height, number of fodder, number of panicles/clumps, weight of 100 harvested dry grains, number of grains/panicles, percentage of smooth grains/clumps and harvested dry grain yield. Substitution of NPK fertilizer with compost straw has no effect on the height of lowland rice plants using the SRI (System of Rice Intensification) method, but does affect the number of productive tillers. The highest number of productive tillers was found in P2 (50% NPK + 50% straw compost), P3 (25% NPK + 75% straw compost) and P4 (0% NPK + 100% straw compost), with an average value of 31, respectively. 27; 28.20 and 27.53 tillers, while treatment P3 (25% NPK + 75% straw compost) and lower values in treatments P0 (100% NPK + 0% straw compost) and P1 (75% NPK + 25% straw compost ) with an average value of 25.83; and 25.67 offspring. Keywords: System of Rice Intensification (SRI), rice, straw compost.

Abstract. Edy Lengkong1*, Friska Malintoi 1, Jemmy Najoan1, Frangky J. Paat1, Tommy B. Ogie1, , Ronny Nangoi1. The Effectiveness Of Liquefied Organic Fertilizer (LOF) Market Waste On Increased Growth and Red-Spinach Production (Amarathus tricolor. L). Ekoton   11. 44-6. Red spinach (Amarathus tricolor L.) is a commodity that has very high development, it is proven that the number of requests tends to increase. Not inferior to other horticultural crops, red spinach plants have a fairly high economic value. Apart from being consumed every time, red spinach also contains nutrients needed by the body (Irwan et al., 2005). According to the Central Statistics Agency (BPS) in 2017, the total harvested area of ​​spinach in Indonesia in 2017 reached 40,608 hectares with a production of 160,248 tons ranks 9th out of 18 commercial vegetables cultivated and produced in Indonesia. There are 3 traditional markets in Manado City, namely Bahu Market in Malalayang District, Karombasan Market in Wanea District, and Bersehati Market in Wenang District. Can giving market waste POC affect the growth and yield of red spinach? The purpose of this study was to determine the effectiveness of giving market waste POC to the growth and yield of red spinach. And knowing the best POC concentration for the growth and yield of red spinach. It is hoped that this research can provide information on the use of market waste as a source of nutrients for the growth and yield of red spinach in the form of liquid organic fertilizer (POC). This research was arranged using a Randomized Block Design (RAK) with 5 treatments of POC concentration of market waste on red spinach plants. P0: control, P1: 25%, P2: 50%, P3: 75%, P4:100%. Each treatment consisted of 5 plant samples and was repeated 3 times to obtain 75 samples. Market waste POC with a concentration of 75% is the best concentration on the variable height of red spinach plants. Keywords: POC, Red Spinach, Market Garbage
