Abstract

Rice stands as an important staple crop in Indonesia and Asia, prompting endeavors to enhance its production. One such technology, aimed at intensifying rice cultivation, involves optimizing plant density utilizing the "jajar legowo" system. This research was conducted within community rice fields located in Pasar Ambacang, Kuranji District, Padang City, West Sumatra, Indonesia, spanning from February 2020 to June 2020. The primary objective of this study was to assess the potential of the jajar legowo planting system, in conjunction with varying dosages of kieserite, to increase lowland rice yields. The study employed a two-factor experiment in a completely randomized design. The first factor is the jajar legowo types: A (25 cm x 12.5 cm x 50 cm) and B (25 cm x 25 cm x 50 cm). The second factor involved different kieserite dosages, comprising three levels (0, 150, 300 kg.ha-1). Each treatment combination was replicated four times. Our investigation unveiled that rice panicle length reached 27.20 cm under the influence of jajar legowo type A with a kieserite dosage of 150 kg.ha-1. Conversely, with the application of jajar legowo type B alongside a kieserite dose of 300 kg.ha-1, the rice panicle length increased to 27.88 cm. The highest yield was obtained with jajar legowo type A at a dose of 300 kg.ha-1, producing 5.35 tons.ha-1. It is recommended to implement the jajar legowo type A cropping pattern with the addition of 150 kg.ha-1 of kieserite, or jajar legowo type B with the addition of 300 kg.ha-1 of kieserite.

Abstract

Cocoa stem borer (CSB) (Zeuzera coffeae) is a main pest on cocoa plant. The research aimed to study the CSB attack in cocoa plantation in Payakumbuh. The research was conducted in cocoa plantation of Payakumbuh from November 2023 to February 2024. Survey method was used in the study and purposive random sampling was used to determine sampling. The criteria to determine locations were ± 0.5 hectare of cocoa plantation and cocoa age was ± 4 years. According to criteria, 2 districts were chosen, Lamposi Tigo Nagari and Payakumbuh Timur. In each district, 5 sub-districts were chosen and in each sub-district, 2 cocoa plantations were chosen. The imaginary diagonal line was formed to determine sampling plants. The result showed that the percentage of attacked plant by Z. coffeae was 0.75% and percentage of attacked stem and branch was 0.70%

Abstract

Sugar palm seed germination does indicate by the appearance of a tissue that extends like a sponge called apokol which is penetrating the hard seed coat and can occur in several positions in germinated sugar palm seeds. No research reports discuss the relationship between this apokol position and the phenology of sugar palm seed germination. This research aims to study the relationship between apokol position and the growth of sugar palm seedlings and their genetic diversity. The research applies Experiment in Completely Random Design with four treatments, each repeated five times. The four treatments are the apokol position, namely A: Apokol in right-center, B: Apokol in left-center, C: Apokol in left-bottom, and D: Apokol in right-bottom. The results showed that the fastest time for the coleoptile emergence was 40 days after transplanting in the right-center apokol position. Morphologically, there was no significant difference in the sugar palm seedling growth with each apokol position. On the other hand, we found that there were genetic diversities among them revealed by Simple Sequence Repeat (SSR) markers. The palm seeds with the right-center apokol position included the first cluster, and the second cluster consisted of left-center apokol, right- bottom apokol, and left-bottom apokol.

Abstract

The study about response of maize (Zea mays) to various plant spacing and fertilizers composition. This research aims to determine the interaction between spacing and composition of chicken manure with NPK fertilizer. In addition, determining the spacing and composition of chicken manure with the best NPK fertilizer on the growth and yield of maize. This research was conducted from February to June 2020 in Limau Manis, Padang City. The design used was a factorial design arranged in a Randomized Block Design (RBD) with 2 factors. The first factor is the spacing which consists of 3 levels of treatment (70 cm x 20 cm; 70 cm x 30 cm; and 70 cm x 40 cm). The second factor is the composition of chicken manure with NPK fertilizer which consists of 4 treatment levels (5 + 50; 10 + 100; 15 + 150; and 20 tons ha-1 + 200 kg ha-1). The research data were analyzed statistically with the F test at the 5% level. The results showed that there was no interaction between spacing and composition of chicken manure with NPK fertilizer. Spacing 70 cm x 20 cm is the spacing that has the best growth and yield, while the composition of chicken manure 20 tons ha-1 with NPK 200 kg ha-1 is the composition of the fertilizer that has the best growth and yield.

Abstract

Shallot (Allium ascolanicum L.) is one of the horticultural crops that is widely consumed by humans. This study aims to obtain interaction the type of mulch and doses of chicken manure on the growth and yield of shallots. This Research was conducted at Panai Pasir Talang , Muara Labuh, South Solok Regency with a height of ± 430 meters above sea level, in December 2018 to February 2019. The research method is an experiments used factorial complete randomized design with two factors. Factors I is the type of mulch (black plastic mulch, silver plastic mulch, rice straw mulch) and factors II is chicken manure (10 tons / ha, 20 tons / ha and 30 tons / ha).. The results showed that there was no interaction between the use of several types of mulch with chicken manure doses on the growth and yield of shallots. The use of black plastic mulch yielded the best results on fresh tuber weight per plot and per hectare of onion namely 1,643 kg / plot and 11.74 tons / ha. The dose of chicken manure of 20 tons / ha gave the best influence on plant height, number of leaves, fresh tuber weight per clump, per plot and per hectare as well as wind dry weight per clump, per plot and per hectare of onion.

Abstract

Rainfall variability, in terms of amount, distribution, and timing, can increase the risk of crop failure and reduce crop yields. This study aims to analyze CHIRPS (Climate Hazards Group InfraRed Precipitation with Stations) rainfall dynamics across several coastal areas of West Sumatra and to evaluate agroclimatic zones to assess the suitability of climate-adaptive cropping patterns. Monthly rainfall data for the period 1995-2024 were analyzed using the IDW interpolation method to produce rainfall distribution maps. This study also classified agroclimatic zones using Oldeman's classification to assess the suitability of cropping patterns. The analysis showed significant annual rainfall fluctuations, with high rainfall dominating the 1995-2014 period and a decline in the 2015-2024 period. Changes in monthly rainfall patterns, particularly the increase in rainfall from March to May during the 2015-2024 period, may affect planting times and irrigation management. The three regions studied (Padang Pariaman, Pariaman, and Padang) are in climate zone A1, with more than 9 consecutive wet months, allowing year-round rice cultivation. However, rainfall fluctuations require adjustments in planting timing and the selection of secondary crops that are more drought-resistant. The results of this study provide a stronger basis for agricultural planning that is more adaptive to climate change, with recommendations for adjustments to the planting calendar and irrigation management to ensure the sustainability of efficient and sustainable agricultural production.

Abstract

This research was conducted in Batusangkar, West Sumatera using factorial research in the form of randomized block design (RBD). The species of Taro that used as the experimental material was Taro type in the age of 4 months. The purpose of this research is (1) to know the interaction between leaves pruning and difference of harvest times to the growth and production of Taro, (2) to know the best leaves pruning for growth and production of Taro (3) to know the best harvest times in order to get the best Taro production. The treatments of leave pruning in this study consisted of; without pruning, pruning by leaving 4 leaves, and pruning by leaving 6 leaves. On the other hand, the harvest times treatment is on 6 months, 7 months, and 8 months. The results showed that the interaction between leave pruning and harvesting times affected taros’ tuber diameter. On the form of tuber wet weight and length, there was no a significant effect due to the treatment provided, yet the pruning by leaving 6 leaves effected to increase the number of tubers and the productivity of Taro. While the best harvest times to increase the productivity of Taro is at the age of 7 and 8 months.
