Abstract

Application of system of rice intensification (SRI) method has been considered as one of powerful efforts to increase the harvested yield by modifying the plant and itssurrounding environment. This study was aimed to determine the effect of different environment towards the response of rice varieties grown using SRI method. Two rice varieties, Batang Piaman and IR-42 were grown in District of Tanjuang Barulak (Regency of Tanah Datar) and District of Saniang Baka (Regency of Solok). Plant height and several yield parameters, such as productive tillers, panicle length, grain number per panicle, and yield per plot were assessed from both varieties and locations. Statistical analysis was conducted using randomized block design (RDB) and significance was further evaluatedusingDuncan’s New Multiple Range Test (DNMRT) with a p>0.05. Batang Pariaman appeared in taller performance than IR-42. Regarding the number of productive tiller, Batang Piaman resulted more productive tillers in Solok, while IR-42 was dominant in number of productive tiller compared to Batang Piaman in Tanah Datar. Unlike IR-42, Batang Piaman exhibited longer panicle, more grain amounts per panicle, and higher yield per plot than IR-42 in both locations.

Abstract

The growth and initial development of the plant greatly determines the survival of the plant at the next stage. This initial phase is also the most sensitive phase of abiotic stress. The level of viability and vigor to produce normal sprouts can explain the success of germination. The aim of this research is to study the temperature change to viabilily and vigor in four rice varieties. Research started from January to February 2018 at Seed Technology and Plant Physiology Laboratory Andalas University and Chemistry Laboratory University Of Padang. This research applies Factorial Experiment in Completely Random Design, where the first factor is four levels of rice varieties, Anak Daro, Batang Piaman, Cisokan and Inpari 30. The second factor is temperature level, 28 0C, 32 0C, 36 0C, 40 0C, 44 0C and 48 0C. Viability and vigor decrease when temperature increase. The optimum temperature for rice germination is 28-32 0 C for Anak Daro, 28-36 0 C for Cisokan, at 28 0 C for Batang Piaman and Inpari 30. Anak Daro and Inpari 30 can germinate until 40 0C. The highest vigor index value at 28 0 C in Cisokan and Inpari 30 (89,33 %). At 28-32 0C Cisokan, Batang Piaman and Inpari 30 has been able to germinate on the second day after planting, but Anak Daro can normal germinate on the third day after planting.

Abstract

Population growth rates cause an increase in food demand, but the planting area is decreasing due to land-use change. The land available to be utilized by farmers is mostly suboptimal land. The disadvantages of suboptimal land are low pH values ​​(4.7) and a small number of nutrients (Nitrogen = 0.11%, Phosphorus = 0.45 ppm, very low Carbon, very high Aluminum, and medium Cation exchange capacity) and for increasing the value of suboptimal land can be given organic fertilizer such as cattle manure and kieserite. This study aims to determine the effect of cattle manure and kieserite on rice growth with the SRI planting system in suboptimal land. The study was carried out in farmers' paddy fields at Ambacang Market, Kuranji District, Padang from June to October 2019. This experiment uses a completely randomized design (CRD). Data were analyzed by the F test at a 5% significance level. If it is significantly different, it is continued with the Honestly Significant Difference test (HSD) at the 5% significance level. The results showed that the application of cattle manure and kieserite can increase the height of rice plants and the number of tillers.

Abstract

Rice (Oryza sativa L.) is an important food crop that is the staple food of more than half of the world's population because it contains nutrients that the body needs. Information on the genetic diversity of local rice scattered in the Kuantan Singingi Regency is still not available. Due to this fact, the genetic diversity of local rice can be identified by DNA analysis. A DNA-based molecular marker that can be applied as a plant genetic marker is SRAP. The SRAP (Sequence Related Amplified Polymorphism) marker system is one of the powerful molecular tools for the clarification of individual sex and estimating the genetic diversity of plant species. This study aims to determine the genetic relationship of rice plants in the Kuantan Singingi Regency through SRAP markers. Twenty-four (24) local genotype samples were used in this study. Observational data were processed using Ms. software. Excel and (NTSYS-pc) version 2.02. The results obtained 17 fragments in Primer M, which resulted in a similarity analysis between 71% to 100%. There are two (2) groups at 75% similarity, then there are five (5) groups at 81% similarity and there are four (4) groups that have 100% similarity. The results of this study are expected to be taken into consideration in developing rice breeding strategies in the future.

Abstract

One of the efforts that can be done is to increase the national corn productivity by developing prolific composite corn varieties. This is done because prolific corn is a type of corn with a tendency to produce two or more cobs, so that it can increase the value of corn production. The purpose of this study was to obtain prolific corn candidates (two cobs) with high yield and uniformity. This research was conducted using the mass selection method. Mass selection is done by selecting plants that have the desired character, namely prolific corn (cob two). The observed variables were the diversity in the F4 population, the percentage of prolific maize, and the comparison of the yield components of prolific maize with non-prolific maize. This study succeeded in obtaining 50% prolific corn on the cob and has wide diversity criteria. Of the 561 prolific corn plants, there are 91 corn plants that are classified as productive prolific. Prolific maize has a higher yield component than non-Prolific maize. Seed weight with cobs on productive prolific corn reached 318 g and seed weight reached 268 g.
