Abstract

Corn is an important food crop in Indonesia which has a function as a source of food, a source of feed and the main ingredient for industry. Corn production in Hulu Sungai Utara Regency has increased from 2018-2020. However, it has not been able to meet market demand for corn because it is constrained by several factors such as lowland swamp land which is used as a place of cultivation with all the problems, namely periodically inundated land, low soil fertility, high soil acidity, toxic substances, lack of micro nutrients, organic matter still raw and others. From the aspect of cultivation technology, the use of superior varieties and proper spacing is influenced by environmental factors, especially climatic factors. The objectives of the study were: 1) Analyzing the interaction of varieties and planting distance on radiation efficiency and growth component of sweet corn (Zea mays saccharata Sturt.) in the lebak swamp land. 2) Analyzing the best varieties and the best planting distance for radiation efficiency and growth component of sweet corn (Zea mays saccharata Sturt.) in the lebak swamp land. This research was conducted in the lebak swamp land of ​​the STIPER Amuntai Experimental Garden, Muara Tapus Village, Hulu Sungai Utara Regency, South Kalimantan Province. At an altitude of ± 2 meters above sea level with coordinates of -2o28' South Latitude and 115o13"' East Longitude from May 2021 to August 2021. This study used a factorial randomized block design (FRBD) method. The first factor is the sweet corn variety (V) consisting of four levels, namely exsotic variety (v1), jambore variety (v2), talenta variety (v3) and ganebo variety (v4). The second factor is sweet corn planting distance (J) consisting of three levels, namely 75 cm x 20 cm (j1), 75 cm x 25 cm (j2) and 75 cm x 30 cm (j3). The results showed that the interaction between varieties and spacing did not affect all observation variables. Varieties affect the observed variables of plant height, number of leaves, leaf area index, plant growth rate, relative growth rate and number of seeds per row. Plant spacing affects the observed variables of plant height, leaf area index and plant growth rate. The best variety is the talent variety (v3) and the best spacing is 75 cm x 20 cm (j1) and the value of radiation use efficiency is 1,5584 g.MJ-1.

Abstract

Shallots are one of the most important commodities in the market and they are easily damaged/rotten. This is due to several factors, including natural factors that often occur and cannot be predicted. One of these natural factors is plant-disturbing organisms. Some of them belong to the phylum Arthropods. This study aims to determine the effect of giving some botanical pesticides on shallots to the diversity of arthropods in the soil in peatlands and to determine the abundance of arthropods. This study used a one-factor Randomized Block Design (RBD) consisting of five treatments, namely without pesticides, chemical pesticides, kirinyuh leaf extracts, kepayang seed extracts and galam leaf extracts with four replications, so that there were 20 experimental units. The parameters observed were arthropod type and abundance. There was an effect of giving botanical insecticides on the diversity of arthropods and the evenness of arthropod species in shallot plants on peatlands. The highest diversity was in the control treatment (1.49) and the lowest diversity was in galam leaf extract (0.96). The highest abundance of arthropods was in the group of arthropods of the scavenger type, which indeed dominated the soil by 86.67%.
