Abstract

Indonesian rice yields are still relatively low. One of the efforts to increase the yield of rice plants is to trim the foliages before flowering, in addition to the application of ‘Unitas Super’ liquid organic fertilizer (LOF). The study was carried out in the Lubuk Lintah Village, Padang City in May - September 2017. The aim of the study was to investigate the effectiveness of pruning, as a source of forage, and the concentration of ‘Unitas Super’ liquid organic fertilizer in improving rice yields. The experiment was arranged in split plot design with main plots consisting of 2 levels, namely pruning at 45 days and without pruning. The subplots consisted of 3 concentrations of ‘Unitas Super’ liquid organic fertilizer, namely 0 ml L-1, 50 ml L-1, and100 ml L-1. All treatments were replicated 3 times. Data were analyzed statistically using the F test at 5% and tested using LSD at 5%. According to the results of the observations, it can be concluded that pruning reduced the weight of 1000 seeds and panicle length, but did not reduce the yield of harvested dry grain and harvest index. Application of ‘Unitas Super’ liquid organic fertilizer did not significantly increase the growth and yield of Black Madras purple rice. The highest dry grain yield was 4.04 t ha-1 observed in plants sprayed with 50 ml L-1 ‘Unitas Super’ liquid organic fertilizer without pruning treatment.

Abstract

The experiment was aimed to determine the most suitable method for selection of salt-tolerant, and to investigate the agronomic characteristics of salt-tolerant rice variety.  Two experiments were conducted to study the tolerance of 18 varieties to salt: 1) in situ screening of salt-tolerant varieties using completely randomized design, and 2) screening of salt-tolerant varieties using factorial experiment (varieties and salinity) with completely randomized design. The experiment showed that screening of rice variety that tolerant and sensitive to salt stress can be determined by comparing root dry weights in salt stressed condition and in unstressed condition, and in term of agronomical aspect, salt stress-tolerant rice showed good growth when planted in the saline field.   Key words: Screening, rice, swamp areas and salt stress
One of the causes of the low productivity of rice grown on peat soils was the high levels of of toxic phenolic compounds in the soil. Development of tolerant rice varieties is one of strategies to grow rice on peat soils. The aims of this research were to select rice varieties tolerant to peat soils and to study the correlation between the plant phenolic acid content with plant tolerance to peat soil.

Abstract

One of the causes of the low productivity of rice grown on peat soils was the high levels of of toxic phenolic compounds in the soil. Development of tolerant rice varieties is one of strategies to grow rice on peat soils. The aims of this research were to select rice varieties tolerant to peat soils and to study the correlation between the plant phenolic acid content with plant tolerance to peat soil. This research was conducted at the Seed Farm Centre Lubuk Minturun, Padang from February to July 2009. The research consisted of two experiments i.e. in peat soil and in mineral soil. The experiments used a completely randomized design using 21 varieties of rice as treatments which were replicated four times. The results showed that there were nine rice varieties categorized as tolerant to peat soil. These tolerant varieties showed higher stress tolerance index (STI), demonstrated by a high level of phenolic acids (coumaric, syringic, and ferulic) in the plant tissues. The STI value had positive correlation with the content of plant phenolic acids, thus the level of plant phenolic acids can be used as an indicator to determine tolerant rice varieties in peat soils. Keywords: peat soil, phenolic acids, tolerant rice, STI

Abstract

Salt solubility is the abiotic pressure which has the most effect on the loss of plant quantity and quality. Salinity not only makes plants stressful but also presents severe constraints on crop production so an attempt to understand plant adaptation mechanisms is important for expanding agricultural production on saline soils. This study aimed to obtain a mechanism for the adaptation of hybrid and composites maize to NaCl stress through anion and cation absorption patterns. The experiments were carried out at the LLDikti Region X Laboratory from May to August 2016. The experiments were arranged in a factorial complete randomized design with three replications. The first factor was corn varieties, namely: hybrid corn (Pioneer 22 and Bisi 12), and composite corn (Bisma and Sukmaraga). The second factor was level of NaCl, namely: 0.0 mg kg-1 NaCl pH 5.0, and 4,000 mg kg-1 NaCl pH 5.0. Measurement of anions and cations using Spectroquant Thermoreator TR Nova 420. The adaptability of hybrid maize and composites to NaCl stress occurred through the mechanism of anion absorption and cation metabolism. The difference in the percentage of NO3-, NO2-, PO4-, NH4+, and K+ levels between hybrid maize varieties and composites showed a difference in the adaptation ability of maize varieties to salinity stress. Keywords: abiotic, mechanism, salinity, varieties

Abstract

Due to physical dormancy, Casuarina equisetifolia seeds have a poor germination rate, which makes it difficult to supply the seeds' needs. Soaking the seeds in hot water is a natural technique to promote water access to the seeds, especially those with a hard outer shell structure. The study's goal was to test if Casuarina equisetifolia seed dormancy could be broken by immersing them in hot water. The experiment used a completely randomized design with a long soaking treatment in hot water, which included soaking for 6 hours in normal temperature water, soaking for 6 hours with water with an initial temperature of 600C, and soaking for 12 hours with water with an initial temperature of 600C, each repeated 8 times. The observed data were subjected to a variance analysis and a F level 0.05 test. If there is a significant effect, the Honestly Significant Difference test is performed at a level of 0.05. According to the findings, breaking the dormancy of Casuarina equisetifolia seeds by soaking them in hot water for 12 hours at an initial temperature of 600C resulted in the best maximal growth potential, germination, and first count germination.

Abstract

This study aims to determine the effect of interactions between peanut varieties and treatment of cow dung. This research was conducted in Kalumbuk Village, Padang City, West Sumatra from September to December 2018. The study was conducted using Factorial Completely Randomized Design. The experimental treatment consisted of two factors. The first factor consisted of 3 peanut varieties, namely varieties of Talam 1, Takar 2 and Tala 1. The second factor was cow dung which consisted of 4 levels namely 0 tons ha-1, 5 tons ha-1, 10 tons ha-1 and 15 ton ha-1. The combination of each treatment obtained 9 units with replications 3 times. The parameters observed were plant height, number of primary branches, number of nodules, age of flower appearance, number of pods, percentage of soft pods, weight of pods per clump, number of seeds, weight of 100 seeds, dry pod weight per plot and per hectare. The results showed that the interaction of peanut varieties with cow manure treatment on the parameters of the number of nodules and the production of the weight of dry pods per hectare was highest, namely in the Talam 1 variety with 15 tons ha-1 cow dung. Keywords: Cow Manure, Peanut Varieties

Abstract

Experiments on the effect of river sludge on the growth and production of rice tolerant of organic acids poisoning phenolics in peat rice fields were carried out in Kenagarian Ketaping, sub-district Lembah Anai, district Padang Pariaman from October 2015 to January 2016 with the aim of knowing the interaction of river mud and acid-tolerant rice varieties organic acids phenolics in peat soil. The experiment was carried out in a randomized block design with the first factor being 3 river mud that were different locations, namely River Mud located 0.5 km from the estuary, river mud affected by sea water 2.0 km from the estuary, and river mud unaffected by eea water 4 km from the estuary, while the second factor is 3 rice varieties tolerant to organic acids tolerance toxic phenolics and 4 replicatons. The experimental results show that river mud can increase the growth and production of rice tolerant of organic acids to poison phenolics in peat rice fields with the highest production obtained in the Sunting Bungo Durian variety followed by Randah Kuning and then Cisokan Kuning varieties.
