REMEDIATION OF DEGRADED SOIL USING UREA AND SINGLE SUPER PHOSPHATE (SSP) FERTILIZERS WITH DIFFERENT CYCLES OF LNTP ZEA MAYS L.) POPULATION AS TEST CROP

Abstract

Agricultural practices have been a way of escape especially in Nigeria from economic meltdown. Unfortunately, our agricultural soils have been infected with toxic substances: such as dumping of refuse, smelting of iron, There is need to improve our soils by either phytoextracting the toxic substances or improve our seeds to withstand low nutrient in the soil. Maize of improved cycles were used for this research. The field and Green house experiments were carried out in the department of Botany, University of Ibadan, Oyo State, Nigeria. Three different cycles of Zea mays (cycle 0, cycle 1 and cycle 3) were collected from International Institute for Tropical Agriculture (IITA), while the degraded soil was obta capacity was filled with 10 kg of soil for both unscreened and screened environment were divided into three divisions for each maize cycle giving a total of seventy added to all the experimental pots uniformly for anchorage. Also, application of Urea fertilizer varying at different concentrations (0 g, 30 g, 60 g and 90 g) was added to 10 emergence indices, percentage emergence and relative growth rate were taken. Data were analysed by one way analysis of variance and means were separated using Duncan Multiple Range Test at pα that the soil was degraded with 96% of sandy soil. The mineral nutrients were of low quantity. The combined application of urea and SSP fertilizer had a significant effect on harmonizing the soil environment by promoting and enhancing the accumulation of soil organic matter. The study showed that out of the three cycles (cycle 0, cycle 1 and cycle 3), cycle 3 performed better than cycle 1 followed by cycle 0 in that order. Increased concentration of Urea fertilizer had significant importance on the m degraded soils which resulted to increase in yield of the three cycles according to levels of urea allocated.

Thirty capacity was filled with 10 kg of soil for both unscreened and screened environment were divided into three divisions for each maize cycle giving a total of seventy-two pots. Single super phosphate (SSP) of 30 added to all the experimental pots uniformly for anchorage.

Growth parameters, estimation of emergence indices, percentage emergence and relative growth rate were taken.

Unfortunately, our agricultural soils have been infected with toxic substances: such as dumping of refuse, smelting of iron, effluents etc. There is need to improve our soils by either phytoextracting the toxic substances or improve our seeds to withstand low nutrient in the soil. Maize of improved cycles were used for this research. The field and Green house experiments rried out in the department of Botany, University of Ibadan, Oyo State, Nigeria. Three different cycles of Zea mays (cycle 0, cycle 1 and cycle 3) were collected from International Institute for Tropical Agriculture (IITA), while State, Nigeria. Thirty-six (36) pots each with 10 Litre capacity was filled with 10 kg of soil for both unscreened and screened environment were divided into three divisions ots. Single super phosphate (SSP) of 30 g per 10 kg of soil was added to all the experimental pots uniformly for anchorage. Also, application of Urea fertilizer varying at different h cycle. Growth parameters, estimation of emergence indices, percentage emergence and relative growth rate were taken. Data were analysed by one way analysis of variance and means were separated using Duncan Multiple Range Test at pα0.05.The soil analysis showed that the soil was degraded with 96% of sandy soil. The mineral nutrients were of low quantity. The combined application of urea and SSP fertilizer had a significant effect on harmonizing the soil environment by promoting and on of soil organic matter. The study showed that out of the three cycles (cycle 0, cycle 1 and cycle 3), cycle 3 performed better than cycle 1 followed by cycle 0 in that order. Increased concentration of Urea aize plants there by promoting the hope on fertility restoration of degraded soils which resulted to increase in yield of the three cycles according to levels of urea allocated.
