Abstract

Biodiversity is an important part of the agricultural ecosystem (agroecosystem) and diversity is determined by the environment and the application of pesticides in the field. Research on the diversity of arthropods in shallot cultivation with different intensities of pesticide application aims to determine the types and populations of arthropods in shallot cultivation on land with different intensities of pesticide application. The research was conducted in the village of Soulowe, which is the center of shallot plants in Sigi Regency, with a massive and intensive application of pesticides, from December 2019 to March 2020. Sampling was carried out using absolute methods (direct observation) and relative methods (Pitffal Traf and Jaring Ayun). The results of the identification carried out in the Unisa and Untad Palu laboratories found that the diversity of arthropods in low-intensity areas of pesticide application was more than that of medium and high applications. There are 7 orders and 13 families, namely Oxyopidae, Grillotalpidae (Ordo Araneae), Scarabaeidae, Coccinellidae (Order Coleoptera), Forficuloidea (Order Dermaptera), Agromyzidae, Muscidae (Order Diptera), Formicidae, Apidae (Order of Hymenoptera), Noctuidae (Order of Hymenoptera) and Acrididae, Gryllidae andTotigonidae (Order Orthoptera). The level of diversity, evenness and family wealth as well as the abundance of arthropod individuals were higher in land with low pesticide application intensity than medium and high pesticide application.

Abstract

Spodoptera frugiperda is a new pest in Central Sulawesi attacks maize crops. It was reported in 2019, known in Sigi, Donggala, Touna, Bangga, Tolitoli, Buol, and Palu City Regencies. Also, this pest is spreading rapidly by threatening maize production in Central Sulawesi. This study aims to measure the population and intensity of Spodoptera frugiperda attacks on maizes in Tulo Village, Dolo Sub-district, Sigi Regency. The study, conducted from January to March 2020, used a survey method and selected sampling. Our location takes each plot measuring 2x2 m. Population observations were carried out by collecting larvae found in the sample plants. The attack's intensity was carried out by counting the number of leaves showing symptoms of an attack on the top leaves. Calculation of the proportion of attacks was carried out by the Davis method. The results showed that the highest S. frugiperda population at the age of 14 days after planting. The intensity of S. frugiperda attack on maize was relatively high at the age of 42 days after planting, with an average attack of 65.24%. Climatic data during this period, an average of 28.76-29.43 ℃ with air influence was 71.1-72%.

Abstract

The purpose of this study was to determine the factors that influence the level of maize production (zea mays) in Losso Village, Sampaga District, Mamuju Regency. The method used in this study to determine the truth of the hypothesis in this study is the method of multiple linear regression data analysis. The results showed that the variable of land area partially has a significant effect on the production of corn farmers in Losso Village, Sampaga District, Mamuju Regency because the probability value is 0.000 <0.05 with the t test result of 4.730. In the regression model the coefficient of X1 (land area) is obtained a value of 1.013, where each additional land area of ​​1%, there will be an increase in production yields of 1.013% assuming the amount of capital and permanent labor. While capital does not have a significant effect on the production of corn farmers, this is evidenced by the results of the t test of (1.168) with a probability value of 0.257.The X2 coefficient of capital (M) is (0.280) which means that every 1% increase in capital will result in an increase in production yields of (0.280)%, with the assumption of fixed land area and labor. The labor variable partially does not have a positive and significant effect on the production of corn farmers as indicated by the t test results of 1.303 with a probability value of 0.208. The X3 coefficient of Labor (TK) is 0.204, where every 1% addition of labor, there will be an increase in production output of 0.204%, assuming land area and fixed capital.

Abstract

This research aims to determine the factors that influence farmers' decisions in using hybrid maize seeds. This research was conducted from July to August 2019 in Sigi Biromaru District, Sigi Regency, Central Sulawesi Province. This research was conducted using a survey method. The determination of the research location was carried out by means of purposive sampling. based on this area the majority of the population is corn farmers. Respondents were determined using the Multistage Random Sampling method, through the following stages, determining the location, determining the farmer groups in each sample village, determining five respondents from each village, in order to obtain a total sample of 20 farmers. The results showed that the factors of age, education, land area, capital, length of farming, extension and access to production facilities together or partially did not have a significant effect on farmers' decisions to use hybrid maize seeds in Sigi Biromaru District, Sigi Regency.

Abstract

Selection and evaluation of the progress of crosses is important to obtain the percentage change and success of crosses. This study aims to evaluate the percentage change in carnelian color up to the F4 generation and the selection progress in the F4 generation. The research was conducted from August 2017 to August 2020 in Kalukubula village, Sigi Regency, Palu, Central Sulawesi Province. This study was structured using a randomized block design with five carnelian color treatments that were repeated five times. This study used a mass selection method by selecting the carnel color according to the treatment (purple, yellow, white, purple dominant yellow and white dominant purple). Each treatment was planted in one plot for each generation. The seeds were planted using an isolation time of 21 DAS. The results showed that there were three color carnelian characters that experienced an increase in the percentage of color up to the F4 generation, namely Purple (27.68% -70.39%), White Dominant Purple (1.52% -16.91%) and White (5.40% -91.22%), and There are two carnelian color characters that experience a decrease in the percentage of color in the F4 generation, namely Yellow (68.14% -64.31%) and Purple Dominant Yellow (27.00%-5.22%). The character of purple, white, dominant purple and white carnelian color had a significant increase in heritability values ​​in the F4 population, and had an expected genetic progression value (36.94%, 17.56%, 53.55%) and positive selection progress in the F4 generation.

Abstract

Post harvest handling is very important to produce quality and high quality seeds. The purpose of this study was to obtain the best post-harvest handling with different storage methods to produce quality and quality seeds with the best germination. This research was conducted in Tamarenja Village (Kalama Valley), Sindue Tobata District, Donggala Regency and seed testing was carried out at the Seed Science and Technology Laboratory, Faculty of Agriculture, Tadulako University. This research was conducted from October 2019 to February 2020. This research was arranged using a two-factor factorial randomized block design (RBD), the first factor consisting of two storage areas, namely: P1 = indoors, P2 = outdoors, while the second factor consists of three storage times, namely: W1 = one month and W2 = two months, and W3 = three months, which was repeated six times so that there were 36 experimental units where each experimental unit consisted of 50 seeds with a total of 1,800 seeds used. Data analysis used Fisher's test and continued with the BNJ test at 1% level. The results showed that the yields stored by hanging outdoors for 3 three months resulted in germination (71.00%), germination time (2.23 days), percentage of moldy seeds (9.33%), and percentage of moldy sprouts (9.33%).
