This study aims to determine the right planting time to obtain optimal sweet corn results in intercropping systems with peanut plants. This research was conducted in the Agricultural Land of Petobo Village, South Palu Village, Palu City, Central Sulawesi for 3 months starting from September to November 2017. The research was carried out using a one-factor Randomized Block Design (RBD), by grouping based on water sources. The treatments that were tried were the intercropping system (TS) planting time, as follows: TS0 = Sweet corn grown together with peanuts; TS1 = Sweet corn planted with 2 WAP peanuts; TS2 = Sweet corn planted with 4 WAP of peanut; TS3 = Sweet corn monoculture. Each treatment consisted of 3 replications so that there were 12 test unit plots. The results showed that the planting time treatment significantly affected the growth and yield of sweet corn on intercropping systems with peanuts. The treatment of planting time together between peanuts and sweet corn gave better growth than other treatments, but the sweet corn monoculture (TS3) treatment gave better results compared to other treatments. Good growth and yield of both plants is recommended at the same time between peanuts and sweet corn in intercropping systems

Growth and production of corn plants require land with sufficient nutrients. Utilization of biological fertilizers and organic materials carried out with the aim of increasing the yield of corn. The treatments that were tried were the provision of compost, livestock manure, compost and livestock manure, each of which was added by spraying a consortium of biological fertilizer. The experiment was designed using a randomized block design with five replications. The results showed that the application of organic-based fertilizers affected plant height from 17 - 49 days after planting, weight of fruit with kelobot, weight of cob and ear length. Provision of compost or livestock manure and added with a biological fertilizer consortium by spray gives a higher effect compared to the provision of compost or livestock manure which is not added to the consortium of biological fertilizer. To increase the productivity of maize plants it is recommended to use a consortium of biological fertilizers applied by spraying at intervals of seven days until the plants are 49 days after planting.

Weeds are not always detrimental to plants, because there is a period of time when they are most influential on plant growth and yield and a period of time when weeds are present is called critical piriode. A research aimed to determine the critical period of sweet corn with weeds in Central Lombok entisoles. The experimental research method with experiments in the field used a randomized block design (RBD), which consisted of 12 treatments, weed-free plants (TBG) from planting to age, 10;20;30;40;50 and 60 days and the plants were allowed to roll (TG). since planting until the age of 10;20; 30; 40;50 and 60 days. The results showed that the presence of tolerable weeds on sweet corn plants was only until the age of 30 days after planting. Weeds must be weeded after the plants are between 30-40 days old, if done after the plants are 40 days old, the crop yields cannot be saved. The critical period for sweet corn competing with weeds on the Lombok Tengan entisol is in the age range between 30-40 days after planting. Plants that compete with weeds for 40, 50, and 60 days after planting (until harvest) experience a decrease in yield of 60.32%, 82.84% and 98.66%. Meanwhile, plants that did not compete (weed free) for only 10, 20 and 30 days experienced a decrease in yield of 98.61%, 80.16% and 61.40%.
