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

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.

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

Upland rice tolerance test trials based on pithy seeds on ultisols used for tuber cultivation and new openings were carried out from November 2019 – February 2021 in Nagari Kampung Pinang, Lubuk Basung sub-district with the aim of knowing the interaction of upland rice varieties on ultisols of former tubers and new openings of ultisols. This experiment was conducted in a factorial Randomized Block Design with two factors. The first factor was the upland rice varieties Rindang I, Luhur I and Barabah, and the second factor was the ultisol treated layer, namely cassava ultisol, onion ultisol treatment layer and new layer processing. Based on the experiment, it was concluded that the three upland rice varieties tested, namely Rindang I, Luhur I and Barabah were classified as tolerant varieties with the order of tolerance being the Rindang I variety, followed by the Luhur I variety and the Barabah variety. Keywords: rice, ultisol, cassava, shallot
