He explains that loam soils that make a ball which breaks on slight pressure are ideal for maize growing. Maize yield is closely related to plant population. Land can be tilled by either using the conventional tillage procedures or conservation. Mugerwa advises farmers with little land such as two acres to use hand hoe for tilling. The manure is churned into the soil at second ploughing at a recommended rate of 4-6 tonnes per acre.Hybrid or OPV seeds?One of the biggest challenges to farmers is poor seeds. When maize plants are grown in the field, tillering only takes place at low plant densities (<3.5 plants m −2), suggesting that small reductions in R to FR ratio could severely reduce tillering in this species (Tetio-Kagho and Gardner, 1988). “Always get advice on how to test soils from extension workers,” Mugerwa says. There are two maize seed varieties; Open Pollinated Varieties (OPVs) and hybrids. Site selectionJames Mugerwa, an extension worker in Buvuma District says that maize is a heavy feeder that thrives in well-drained, well-aerated, deep warm loam soils. By using two seeds per hole, this requires 10 kilogrammes of seed per acre and an optimum population of 21,000 plants.

Having more than 75,000 plants per ha will not increase yield unless growing conditions are very favorable with a yield potential of >13 t/ha.

Most favorable planting densities for high yield in the tropics are probably in the range of 65,000 to 75,000 plants per ha. Best Management Practices More on this topic. “Planting requires proper management practices to attain potential yields,” says Mugerwa. Land preparationMugerwa says land preparation is extremely important. There is a box to contain fertilizer, so the seed can drop into the soil with fertilizer, but won’t hurt the corn seedlings. The second rainy season is expected to start early this month and as expected, it is time for farmers to plant maize and other crops.The first step towards obtaining good maize harvest is ensuring that the farm is well-ploughed and ready for planting. Farmers should avoid late planting since it leads to increased incidences of pests and disease attacks hence reduced yields. Ploughing should go a depth of at least 20cm and should be conducted two to three weeks before the onset of the rains. “Burning the residues destroys plant nutrients which cannot be easily replaced,” he says. However, there are limitations to increasing plant population under humid, tropical conditions. Mugerwa says that seeds should be selected depending on the adaptability to production conditions, resistance to pests and diseases and length of the growing season. As a standard procedure, he recommends the application of compost or animal manure after the first cultivation to allow for adequate composting. He explains that making a decision on the variety of maize to be planted is an important aspect. To ensure a more uniform crop stand and lesser missing hills, plant 2-3 seeds per hill and thin after 14-20 days to allow only one plant to mature. Planting Maize should be planted on the onset of rains to take advantage of the nitrogen flush effect which is the release of accumulated nitrogen in the soil during the dry season. This allows the breakdown of all organic matter,” he says.New sites or those that are bushy should first be slashed before ploughing the residues into the soil. All rights reserved.

Hand hoes are convenient for smallholder farmers while use of oxen should not be used in sites with heavy soils ad steep terrain. Select an optimal plant spacing that allows for ease of field operations, such as fertilizer application or weeding, minimizes competition among plants for light, water, and nutrients, and creates a favorable micro-climate in the canopy to reduce the risk for pests and diseases. OPVs can be recycled up to two years but the selected plants are marked before harvesting and stored separately.

This reduces weed competition and loss of soil moisture from evaporation. A farmer should use appropriate technology that minimises costs of production,” he says. (Part II), Luweero to hold 5th District Woman MP polls in 10 years, The sad reality of resumption of regulated sports with limited avenues for revenues. Corn planter is a machine to plant corn with high working efficiency, and our company has designed a new type of corn planter machine with 2 rows, 3 rows, 4 rows, 5 rows, 6 rows or 8 row, which means you have many options about it.
