ABSTRACT:

Two separate researches were conducted in northern Nigeria. The first study (1996/97) covered Kano, Jigawa and Katsina States and the second (2002/03) covered Kano and Katsina States. These States have high agricultural production potentials and are significant in both biophysical characteristics and population density for the larger part of northern Nigeria. These two researches compared the seed types and quantities of chemical fertilizers used in the two separate agricultural seasons. The results showed that traditional crop varieties for sorghum (such as Farafara, Kaura and Mori), millet (such as Zango and Dan Akaranja) and cowpea (such as Dan wuri and Dan Illa) dominated the cropping system compared to improved varieties for these crops such as Yarshawa, Gaya early and Samsorg 15 for sorghum, Ex-Bornu and Lawur for millet and Kananado and ITA 60 for cowpea. However, for groundnut, improved varieties such as RMP 12, RRB, Ex-Dakar and Yarkabara were more prevalent than local ones such as Yar Tsugune and Jar Jigilla. The average rates of application of chemical fertilizer were 74.28 kg nutrient ha-1 in 1996/97 and 54.37 kg nutrient ha-1 for 2002/03. These application rates fell short of the recommended rates for some staples such as 220 -240 kg nutrient of N P K ha-1 for open-pollinated maize, 300 kg nutrient of N P K ha-1 for hybrid maize, 200 – 300 kg nutrient ha-1 for sorghum, 100 – 200 kg nutrient ha-1 for millet and 200 – 350 kg nutrient ha-1 fo
