Abstract

The demand for onions in Indonesia is always increasing, but shallot production has not been able to meet the needs of the community. The purpose of this study was to obtain the best accessions that can be used in the selection of plant breeding that has the best potential in the Karawang area. So that it can increase the productivity and resistance of shallot plants in the lowlands of Karawang. The onion research was carried out for 3 months, starting from December 2021 to March 2022. Located in UNSIKA New Land, Pasir Jengkol Village, Majalaya District, Karawang Regency, West Java Province. The location of the coordinates is 6ᵒ18'5"LS and 107ᵒ20'24"E, with an altitude of 15 meters above sea level (Google Earth). This study was arranged using a Randomized Block Design (RAK) with 8 treatments (shallot accessions) and 4 replications, in each replication there were 4 samples with a total of 128 experimental units. Data were analyzed using analysis of variance and further test with DMRT (Duncan Multiple Range Test) at 5% level. The results of this experiment showed that there was a significant effect on the appearance of the agronomic characterization of shallot accession on the growth and yield components (number of tillers, wet bulb weight per plant, dry bulb weight per plant). Accession BLR7 (Blue Lancor) gave the highest average yield on the number of tillers of 12.4. Accession BLR7 (Blue Lancor) also gave the highest yield of wet tuber weight per plant, which was 23.84 grams. Accession LKG1 (Lokal Karawang) gave the highest yield on tuber dry weight per plant of 18.58 grams

Abstract

Shallot is one of the horticultural commodities that has high economic value because its existence is very much needed by the people of Indonesia. This study aims to determine the exact concentration of BAP that can provide the best agronomic performance on several varieties of shallots in the lowlands. This research was conducted from December 2022 to May 2023 at the Screen House of the Faculty of Agriculture, Singaperbangsa University, Karawang which is located in Pasir Jengkol Village, Majalaya District, Karawang Regency. The research method used was Factorial (RAK) which consisted of 12 treatments and each treatment was repeated 3 times so that there were 36 experimental units in total. The first factor is variety which consists of 3 levels, namely v1 (Dayak), v2 (Sumenep), v3 (Bima Brebes). The second factor was the concentration of BAP which consisted of 4 levels, namely b1 (0 ppm), b2 (25 ppm), b3 (50 ppm), b3 (75 ppm). The effect of treatment was analyzed using analysis of variance and if the F test at 5% level was significant, then it was continued with a 5% DMRT follow-up test. The experimental results showed that there was no interaction between the several varieties and BAP concentrations on all observed parameters. however, the results showed a significant effect on the independent factor of the variety. Variety v1 (Dayak) was able to produce the highest number of tillers, fresh weight of stover, fresh weight of tubers per clump, dry weight of stover and dry weight of tubers per clump compared to v2 (Sumenep) and v3 (Bima Brebes). The independent factor of BAP concentration did not have a significant effect on all observed parameters.

Abstract

Intercropping system is closely related to the planting of different plant commodities at the same time and land, so it is not surprising if it creates positive or negative interactions between plants. Thus, efforts to regulate the proportion of plants in intercropping are important to be considered. The aim of study to obtain the best intercropping proportions in cauliflower and soybean crops. The research was conducted on Bintang Alam land, Telukjambe Timur, Karawang District in December 2022 - March 2023. The research was used experiment method with Randomized Block Design (RBD) single factor with 5 treatments of intercropping proportions repeated 5 times. The treatments given were; K1 = 100% cauliflower, K2 = 25% cauliflower + 75% soybean, K3 = 50% cauliflower + 50% soybean, K4 = 75% cauliflower + 25% soybean, K5 = 100% soybean. The results were analyzed with the F test at the rate of 5% and further tested with the Least Significant Difference (LSD) at the rate of 5%. The best intercropping system proportion was K3 treatment (50% cauliflower + 50% soybean), with the largest LER value of 1.49 and a balanced ratio of crop CR values of 0.72 (cauliflower) and 0.54 (soybean). The production per plot that can be produced from K3 treatment was 2.01 kg/plot (5.03 tons/ha) of cauliflower and 0.43 kg/plot (1.08 tons/ha) of soybean.Keywords : Intercropping, Planting proportion, Cauliflower, Soybean
