Efffects of Nitrogen application on growth and yield of snowpeas (Pisum sativum)

Njoroge, P.K.



An experiment was carried out at the Kabete Field station farm, University of Nairobi between March-July 2000 (season I) and between June-September 2000 (season II) to determine the effect of application of different levels of nitrogen (N) fertilizer application on growth and yield of snowpea. Snow pea variety “Oregon sugar pod II” was used. The experiments was  laid out in a complete randomized block design with three replicates. Four  N levels (0, 50, 100 and 150 kg N ha-1) were split applied in equal halves as CAN (26% N) at 29and 58 days after planting (DAP). Plant height, leaf area index, above ground dry mass, number of pods and pod dry mass were determined overtime. All the growth and yield parameters studied did not substantially benefit from N fertilizer application. It is therefore recommended that less N be applied for growth and yield of snowpeas.
