“…This is to the opinion of [13] that soil can be categorized as having saline content if it has passed the Electrical Conductivity test and produces a value of more than 4 dS/meter. This is also supported by the opinion of [14] that the salinity content of 8.19 dS/m belongs to the high salinity criteria.…”

The study aimed to examine the dose of urea fertilizer, the inoculation dose of Rhizobium sp., and the doses of phosphate solubilizing bacteria, as well as the interaction between the two in soybean cultivation in saline soils. The study was carried out from July to November 2021 at the Ecology and Plant Production Laboratory, Greenhouse, and Chemical Analysis, Faculty of Animal and Agriculture, Diponegoro University, Semarang. A factorial 3 x 4 Completely Randomized Design (CRD) with 3 replications was the research methodology used. The dosage of urea fertilizer, with N0 = 100%, N1 = 90%, and N2 = 80%, is the first factor. The second factor is the dosage of Rhizobium sp. and phosphate-solubilizing bacteria that are inoculated, with P0 = No inoculum (control), P1 = 3 g/seed, P2 = 6 g/seed, and P3 = 9 g/seed. According to the research, it can be concluded that Rhizobium sp. and phosphate-solubilizing bacteria, along with urea fertilization, had a significant impact on plant height and early flowering but had no significant on the number of leaves and wet weight of pods generated in saline soil.

“…Sweet corn can grow optimum at rhizospheric temperatures in the range of 21-30 o C [69,70], as long as peanuts need an optimal temperature of 20 -30 o C [11], soybeans at 25 o C [30,71], red beans at a temperature of 16-24 o C [72], cowpeas at a temperature of 18 o C [73], and mung beans approximately 15 o C [74]. Intercropping can increase shade in the planting system compared to monoculture corn, reduce water evaporation, conserve soil moisture and improve soil fertility to increase yields [75].…”

“…The saturation rate of photosynthesis of crop group C 3 , such as legume, is achieved at a lower light intensity than crop C 4. The level of light saturation for individual leaves of crop group C 3 is conducted in the range of 50% total light [30]. The rooting system of sweet corn and legumes is also different to avoid nutrient competition in the root part of the crop [31].…”

Sweet corn is generally grown in monoculture with wide spacing because it is easier to do but less effective and efficient in using resources, which cause the microclimate around sweet corn to be not optimal for its growth. Intercropping can improve the microclimate due to the presence of intercrops between the sweet corn. The type of intercrops affect the microclimate around sweet corn. This research aims to determine the effect of various legumes on the abiotic environment and find the legumes that can create an optimal abiotic environment for sweet corn. This research was conducted in 2019 using a single factor experimental method that arranged in a complete randomized block design with three blocks as replications. The treatments were legumes consisting of peanuts, soybeans, cowpeas, red beans, and mung beans. In addition, sweet corn is also planted in monoculture as a control. The research results showed that legumes among sweet corn could decrease daylight intensity above soil level with the most significant light extinction coefficient on the intercropping of sweet corn with soybeans, but has no significant effect on soil temperature and humidity. Soybeans and cowpeas are more suitable as intercrops on sweet corn intercropping to improve the environment.

“…This condotion can be happened because during the age of 45 DAP, plant height of corn is more than 100 cm, while plant height of rice crop is less than 60 cm, so that both of rice crop varieties were shaded. According to [12], The rice crop which are shaded by corn in the rice-corn intercropping system shown on the lower the sunlight received by the rice plants, the more dense the level of shade will cause the growth and yield of rice become to decrease.The high population density of plant is not always followed by increasing the yield, due to the level of competition inter individual plants also increase.…”

Intercropping is an attempt to plant several types of crops on the land at the same time, arranged in such a way in a row of plants. Planting in this way can be done on two types of plants that are relatively different old. The application of Rice-Corn intercropping was carried out in Playen District of Gunungkidul. Rice seed was used Sidenuk and Inpari 42 varieties then planted at distance of 40 cm x 20 x 12.5 cm (Tajarwo 2:1). The corn seed used Pioneer 35 and they are planted at 60 cm x 25 cm. The purpose of this research is to examine the application of intercropping rice-corn compared to monoculture cultivation on the aspects of soil nutrients status, affects intercropping on both crops yield and feassibility analisys of the intercropping farming on the two different agricultural system. The results of study show that on intercropping pattern rice yield can reach 5.19 to 5.85 ton ha-1 and dry corn shells from 5.43 to 6.28 tons ha-1 and quite profitable with a B/C ratio of 2.68 and R/C ratio of 3.12 compared to rice or corn monoculture planting patterns alone with B/C ratios of 1.24 and 1.88, respectively
