EFFECT OF DIFFERENT DOSES OF NITROGEN AND SOWING DATE ON THE YIELD OF PEA
(Department of Soil Science, 2006) SULTANA, NIGER
A held experiment was conducted at the Sher-e-Rangla Agricultural L niversitv itrni during the period from November. 2005 to February, 2006, to find out the opumun) levels of N and sowing date for maximum yield of pea. there are IS treatments combinations comprising of four levels nt N (0. 30. 60 and 90 kg N ia . ouc iimllv organic and another one control. The treat ments were: T j = Control. I: = 30 kg N/fm. 1 = 60 kg N/ha, T 4 = 90 kg N/ha. 'I's = PKS but no N, T= Organic. A common dose of 75 kg I'205 ha 1 . 60 kg 1(20 ha', (;ypsuni 10kg ha 1 and 7.nSO4 2 kg ha were applied to all plots except control and organic ploL. There were three sowing date. November 8 November 28th• 2005 and December 0". 2006. The maximum plant height ( '..531n }. highest number of branches/plant (.1.62), Itighest yield of green pod (7.04 u'ha). highesi number of pods planrI (8.33), highest matured seed yield (2.02 I/ha), were recorded under the treatment 90 kg N ha as well as at the sowing date November 28. The yields due to different treatniejits ranked in the order of >i'>T>T1 The interaction effect of sowing date and different doses of fertilizer showed statistically significant difference in consideration of tzreen pod yield. matured seed yield and non significant effect on plant height, number of pods plani etc. The maximum NPK content in plain tissue were recorded at the sowing date November 28. From the viewpoint of yiekl and nutrient content of garden pea and the nutrient requirenwnt of the crop. the N. P and K combination at the rates of 90 kg N, 75 kg P 205 and 60 kg 1(20 /ha was considered to he the balanced combination of fertilizer and 28 ththe maximum output through cultivation of pea in Deep Red Brown Terrace Soil of SA Ii Lhrm. November, is the optimum sowing date for
