Abstract

Potato (Solanum tuberosum L.) is of important major crops for its carbohydrate and plays important roles to support food sovereignty along with rice, wheat, corn, and sorghum. Potato growth and yield at West Sumatra has not reached its maximum potential due to some factors including cultivation. One major important constraint in potato growing in West Sumatra is the fact that farmers use the 8th to 12th generation of potato seedlings which have a very low agronomic potential. Yet, weeds have caused another problem in the field and reduce potato yield. An experiment has been conducted at the Laboratory of Microbiology, Faculty of Agriculture, Universitas Andalas and Nagari Alahan Panjang, Subdistrict Lembah Gumanti, Solok Regency from November 2018 to March 2019. The experiment was aimed at determining the best indigenous rhizobactria isolates to increase the growth and yield of potato plants as well as weed population dynamics associated with potato plants. Six isolates of indigenous rhizobacteria and a control treatment group were tested in a completely randomised design with three replicates. The isolates were L1 S3.1, L1 S3.2, L1 S4.4, L2 S1.2, L2 S2.3, L2 S3. 2. Data were analyzed with analysis of variance and mean separation with Duncan's New Multiple Range Test (DNMRT) at 5%. Results showed that isolate L1 S4.4 was best in increasing the number of branches, number of tubers, and weight of potato yield. The isolates tested affected weed populations dynamics, prior to treatments there were 8 species of weeds found at the field i.e Bidens pilosa L., Leptochloa chinensis, Eleusine indica L., Agerathum conyzoides, Richardia sp, Galinsoga parviflora, and Sonchus arvensis. During potato growing at the field, weed species of Eleusine indica L. and Gynura divaricata dissappeared from the soil. In contrast,  Amaranthus spinosus emerged demonstrating that weed population dynamic has occurred.

Abstract

Research on the effect of giving various concentration ethepon to growth and production of cucumber was conducted in Nagari Kacang Kecamatan X Koto Singkarak, Solok, West Sumatra, from June to August 2008. The objectives of the study were (1) get interaction between several concentrations of ethephon with cucumber varieties, (2) obtaining the best ethepon concentration, (3) and knowing cucumber varieties that have better production. Factorial-factored experiments in Randomized Block Design with 2 factors and 3 groups. The first factor of ethepon concentration consisted of five levels 0, 100, 200, 300, 400 ppm. The second factor is cucumber varieties of Local and  Antara varieties. Observed variables: plant length, number of branches, when first male flowers appear, when the first female flowers appear, the number of male flowers, the number of female flowers, the number of straight fruit, the number of fruit is not straight, the fruit weight is straight, fruit weight is not straight. Providing ethepon concentration with crop varieties has an effect on growth and production of cucumber , that is when the first male flowers appear (hst). Provision of ethepon concentration of 200 ppm showed a better effect on the number of female flowers, the number of straight fruit, and the weight of the fruit straight. Factor varieties, singularly different to plant length variables, when the first female flowers appear, the number of straight fruit, the number of crooked fruit, the weight of the fruit straight, and the weight of the bent fruit. Local varieties show better production than Antara varieties.

Abstract

This Research aimed to select wheat genotypes which potential to be developed in a high rainfall area. It was conducted at September 2012 to January 2013 in Alahan Panjang, Solok Regency, West Sumatera. Seventeen wheat genotypes were planted at Alahan Panjang, Solok, West Sumatera from September 2012 – January 2013, including local varieties (Nias, Selayar, Dewata). It used random design block with 3 replications and 10 samples each block. If genotypes were significant according to test f then continued by test duncan on standard 5 %. Observed variables were amount of spikelet per spike, amount grain of spikelet, amount of floret per spike, spikelet length and width, grain length and width, amount of full grain, amount of unfull grain and a thousand grain weight. The result showed that UAGDM 13 had a good amount of spikelet per spike. All genotypes had high amount of floret per spike except UAGDM16. A good spikelet length was belonged to all genotypes except UAGDM11 and UAGDM13. Grain length and width were not significant among all genotypes. Three genotypes which had a high amount of full grain were UAGDM5, UAGDM6 and UAGDM17. Genotype UAGDM1 was the best of a thousand grain weight.

Abstract

Potato (Solanum tuberosum L.) has been classified as major source of carbohydrate along with rice, wheat, and corn. As for other crops, potato’s growth and yield are always subject to weed interference. An experiment has been conducted to study the effect of indigenous rhizobacteria to promote the growth and yield of potato var. Cingkariang and weed population at Nagari Pakan Sinayan, Agam District, the Province of West Sumatra. The experiment used a completely randomized design with seven treatments and three replications. The treatments was rhizobacteria indigenous to potato farm at Nagari Pakan Sinayan i.e SWL2.2, Ag2L2S3.3, Ag2L2S4.2, Ag3L3S3.1, Ag3L3S5.1, Ag4S5.2, and one group of without the isolate. Data were analysed with analysis of variance and mean separation following DNMRT at 5%. Results demonstrated that indigenous rhizobacteria promoted plant height, number of branches, and the weight of potato tubers. The rhizobacteria also resulted in changes in weed population. Ten weed species were found prior to the experiment as follows: Ageratum conyzoides L.,  Alternanthera philoxeroides (Mart.) Griseb., Andrographis paniculata (Burm.f) Nees, Bidens pilosa L., Cyperus rotundus L., Crassocephalum crepidioides (Benth.) S. Moore, Eleusine indica L., Echinochola colona (L.) Link, Galinsoga quadriradiata Ruiz & Pav., dan Paspalum commersonii Lamk. However, three new weed species emerged during the experiment. They are Amaranthus spinosus L., Portulaca oleracea L., and Paspalum conjugatum P.J.Bergius indicating changes in weed population.
