Abstract

Identifikasi suatu varietas yang memiliki hasil tertinggi pada suatu lingkungan tertentu mendasarkan pada nilai genotipe dan interaksi genotipe x lingkungan sangat bermanfaat bagi pemulia dan petani. Estimasi hasil suatu varietas mendasarkan pada nilai genotipe dan lingkungan masih belum cukup. Tujuan penelitian adalah untuk menunjukkan kegunaan model analisis AMMI (additive main effect and multiplicative interaction) dalam identifikasi stabilitas hasil dan adaptabilitas suatu verietas. Data produksi tujuh galur padi Fe tinggi yang ditanam delapan kondisi lingkungan digunakan dalam analisis untuk mencapai tujuan penelitian. Hasil penelitian menunjukkan galur G2 merupakan genotipe ideal karena memiliki produksi gabah tertinggi dan memiliki stabilitas tertinggi, serta memiliki kemampuan adaptasi luas. Analisis model AMMI menggambarkan pola interaksi suatu genotipe dengan lingkungan, menggambarkan kesesuaian suatu genotipe dengan suatu lingkungan, nilai nominal hasil suatu genotipe pada suatu lingkungan, stabilitas suatu genotipe, adaptabilitas genotipe, dan pola hubungan lingkungan dengan genotipe.

Abstract

Many papers have reported that Fe deficiency caused anemia is a worldwide problem. It has also been reported that most of the Fe intake of people came from cereals. To improve Fe nutrition of rice consumers, grain Fe concentration must not only be increased, but it must also be in a form that available to consumers of rice. This study set out to determine the bioavailability of Fe in rice of 10 varieties. Results indicated that bioavailability of rice grain Fe varied among different varieties. Three varieties (Maligaya Sp., Bengawan Solo, and Gilirang) had a higher Fe bioavailability than the standard of IR 64. There was no correlation between bioavailability of Fe and grain Fe concentration in rice grain.

Abstract

Upland rice plays an important role in supporting food security for community in dryland areas. Genotype × environment interaction is an important factor to be considered in the development of upland rice in Indonesia, because they affect rice yield stability. Genotype × environment interaction and yield stability of rice genotypes are important information to be considered for the development of upland rice. The study was conducted over two years on a dry land area of Banjarnegara, Central Java, using 10 genotypes of upland rice (UNRAM 1E, 4E UNRAM, UNRAM 17E, 9E UNRAM, Unsoed G10, G19 Unsoed, Unsoed G39, G136 Unsoed, B12644F-MR-2, B12498C-MR-1) and two varieties (Situ Patenggang and Way Rarem) as control. Data were analyzed using analysis of variance. Results showed that planting time affect yield and yield components of the upland rice tested. Effect of the genotype x planting time interaction was shown on plant height, flowering date, harvest age, and crop yields. The upland rice genotypes that showed a stable high yields over years of planting were UNRAM 4, Unsoed G10, G136 Unsoed, B12644F-MR-2, and Situ Patenggang and Way Rarem.

Abstract

Light use efficiency is a crucial parameter in plant growth associated with accumulation of energy interception. Nitrogen and phosphorus deficiency reduce leaf area index (LAI) and specific leaf nitrogen and phosphorus (SLN and SLP) content and reduce efficiency of light intercepted by plant canopy structure. This research was conducted in Kebun Bunga Mayang PTPN VII, North Lampung Regency, Lampung Province (04050’S, 104052’E, 38 m above sea level) from July 2008 to September 2009. Treatments were distributed in the field under a randomized complete block design factorial with three replications. The increase in nitrogen fertilizer (N) improved sugarcane light use efficiency. The light use efficiency of the sugarcane plants fertilized with 225 kg N ha-1 was 2.29 g MJ-1 at maximum stem phase. On the contrary, the increasing of phosphor (P) fertilizer did not affect light use efficiency but increased stem dry matter at maximum seedling phase or about 3 month after planting (3 MAP), at maximum stem phase (9 MAP), and at harvest (11 MAP); total dry matter at seedling phase (5 MAP) and at maximum stem phase (9 MAP). Nitrogen did not interact with P in affecting light use efficiency. Keywords: fertilization N and P, interception radiation, light use efficiency, sugarcane

Abstract

The study aimed to determine the dynamics of soil moisture in various standing water levels and dosages of organic fertilizer. The experiment was arranged in a Completely Randomized Block Design (CRBD) with a 3 × 3 factorial treatment in 3 replicates. The first factor was 3 different water levels, namely 10 cm (T1), 20 cm (T2), and 30 cm (T3). The second factor was 3 levels of dosages of organic fertilizer, namely 0 g pot-1(P1), 35 g pot-1 (P2), and 70 g pot-1 (P3). The highest of soil moisture was obtained in the 10 cm water levels and 70 g organic fertilizer (T1P3) and the lowest in the 30 cm water levels and without organic fertilizer (T3P1). The highest infiltration rate was obtained in the 30 cm water levels and 70 g pot-1 organic fertilizer (T3P3), the 30 cm water levels and 35 g pot-1 organic fertilizer (T3P2), the 20 cm water levels and 70 g pot-1 organic fertilizer (T2P3), and the lowest in the combination of the 10 cm water levels and without organic fertilizer (T1P1). The highest capillary rate was obtained in the combination of the 30 cm water levels and 70 g organic fertilizer (T3P3) and the lowest in the combination of the 30 cm water levels and without organic fertilizer (T3P1).

Abstract

The objectives of the research were to determine the best varieties of celery and nutrient concentration with the addition of azolla extract for growth and yield of celery, and obtaining the best combination of varieties and nutrient concentrations for growth and yield of celery in the hydroponic floating system. The research was conducted at Screen house number A. 24 and the Laboratory of Agronomy and Horticulture, Faculty of Agriculture, Jenderal Soedirman University and was conducted from January 2020 to April 2020. The research was arranged in a two-factorial randomized block design. The first factors were varieties treatment (V): V1 (Summer variety), V2 (Amigo variety), V3 (Tall Utah variety). The second factors were treatment of nutrient concentration (K): K1 (AB mix solution 900 ppm + azolla extract 60 ml / l), K2 (AB mix solution 1100 ppm + azolla extract 60 ml / l), K3 (AB mix solution 1300 ppm + azolla extract 60 ml / l), K4 (AB mix solution 1500 ppm without azolla extract). The research variables observed were plant height, number of leaves, amount of chlorophyll, fresh root weight, dry root weight, fresh shoot weight, dry shoot weight, root length and number of stalks. The results showed that the Tall Utah variety and the nutrient concentration of 1300 ppm + 60 ml / l azolla extract was the best treatment for growth and yield of celery. The interaction between the two treatments of Tall Utah varieties and nutrient concentrations of 1300 ppm + azolla extract 60ml / l showed the best treatment on the variable number of leaves 39.16, total chlorophyll 49.91, fresh root weight 7.57 g, dry root weight 0, 73 g, dry shoot weight 2.11 g, root length 9.11 cm, and the number of petioles 8.94 pieces.
