ABSTRACT:

Two experiments were conducted in 2019 and 2020 dry seasons at the Teaching and Research Farm of Samaru College of Agriculture, Ahmadu Bello University Zaria ( 11° 11′ N, 07° 38′ E, and 686m above sea level) which is located in the northern Guinea Savanna ecological zone of Nigeria, to determine the best garden cress cultivar suitable to northern guinea savanna and optimum Nitrogen fertilizer rate for better performance of the vegetable. The treatments consisted of two accessions of garden cress (HALIM and EX−JABA) and four level of nitrogen fertilizer ( 0, 30 , 60 and 90 kgNha-1) which factorially combined and laid out in a randomized complete block design. The treatments were replicated three times. The results obtained indicated HALIM accessions recorded the highest number of leaves plant-1, number of branchesplant-1, fresh biomass and dry biomass. The use of 90 kgNha-1 recorded the highest value for the aforementioned growth character and vegetable yield (kg ha-1).It can therefore be concluded that HALIM accessions performed better than EX-JABA in terms of growth characters, while application of 90 kgNha-1produced the best growth and yield of garden cress.
