Abstract
A field experiment was conducted during 2013/2014 dry season at Minjibir irrigation scheme, along Jakara River, Kano State located at Longitude 8o30”E to 8o 32”E and Latitude 12o5”N to 12o20”N at 414 m above mean sea level. The study examined soil and water management strategies on sodic soil condition for the production of tomato.The experiment consisted of four levels of gypsum application (0g/m2, 200g/m2, 300g/m2 and 400g/m2) and three levels of leaching requirement (100%, 150% and 200%) arranged in a completely randomised design laid as treatments in plots (2m x 2m) basin and replicated three times. The irrigation water was applied to each plot through a calibrated PVC pipe. The irrigation water quality assessment was conducted for ESP, SAR, EC and pH and the results were 60.3%, 25.0, 1.4dS/m and 7.23 respectively. The Tomato seasonal water requirement was computed using CROPWAT software 8.0 and the result was 564.3mm while the leaching requirement of 1.49mm/day was also calculated. The results showed that there was statistically high significant difference on yields with respect to gypsum application and leaching requirement (LR) at 1% level of significance. The highest yield of 25 ton/ha was obtained from the plot treated with 400g/m2 of gypsum at 100% leaching requirement. The lowest yield of 18.75ton/ha was realised from plot treated with 200g/m2 of gypsum at 150% LR. However, there were no yields from plots with zero gypsum application due to high sodic condition. It was identified that to grow tomato in Minjibir irrigation farm, reclamation is necessary and the leaching requirement should be kept at 100% in order to achieve better yield and yield components. About 87.1% of tomato seedlings survived when transplanted in plot treated with 400g/m2of gypsum whereas only 52.75% of tomato seedlings survived in plot treated with 200g/m2 of gypsum.
