Effect of Soil Organic Ameliorants with Carbonized Rice Hull on the Growth and Yield of Shallot Onion (Allium ascalonicum L) on Salt Affected Soil

Abstract

A pot experiment was conducted to test the potential of different soil organic ameliorants in salt affected soils reclamation; to test the effect of soil organic ameliorants on the growth and yield of shallot onion (Allium ascalonicum L.) planted in salt affected soil; determine the most effective soil organic ameliorants on salt affected soil Treatments prepared were; T1- Control Salt affected soil (1.57 kg/pot-1), T2- Vermi-cast (197.40 g/pot-1) with CRH (30 grams/pot-1),T3- Guano dung (39.40 g pot-1 with CRH (30 grams/pot-1), T4- Dried Goat Manure (115.40 g/pot-1) with CRH (30 grams/pot-1), T5- Dried Chicken Dung (94.94 g pot-1) with CRH (30 grams/pot-1), T6- Dried Cattle Manure (214.30 g/pot-1) with CRH (30 grams/pot-1). The study was laid out using Randomized complete block design with treatments and three replications. All organic ameliorants applied to the salt affected soil significantly improved on   average bulb diameter, average height, average number of leaves, average bulb fresh weight, average number of tillers and average yield per hectare. It can be concluded that application of organic ameliorants is effective means to address the problem in saline affected soils.
