Abstract:
Field
study was conducted during 2001-02 and 2002-03 to investigate the effect
of cropping patterns and farm yard manure, potassium and zinc on the
grain yield of wheat. Trials were conducted at Agricultural Research
Farm, KPK Agricultural University Peshawar, Pakistan. Two factors
cropping patterns and manures/fertilizers were studied in the
experiment. Randomized complete block design was used with split plot
arrangements and four replications having net plot size of 12 m2.
Wheat variety Ghaznavi-98 was sown in November soon after ploughing the
soil at proper moisture level suitable for wheat seed germination. Five
cropping patterns were allotted to main plots and the eight combinations
of FYM, K and Zn to the sub-plots. Same plots were used for next year
sowing. Effects of five cropping patterns i.e., rice-wheat, maize-wheat,
sunflower-wheat, sorghum-wheat and pigeon pea-wheat and three organic
and in-organic fertilizers (Farmyard Manure, Potassium and Zinc) on
subsequent wheat crop were observed. Highest grain yield was obtained
when wheat was planted after pigeon pea. Manures/fertilizer application
(Farmyard Manure, Potassium and Zinc) produced significantly higher
grain yield than the control plots. The findings of the present study
revealed that leguminous crops can significantly increase the yield of
succeeding crops. Thus use of Farmyard Manure, Potassium and Zinc should
be included in integrated crop management approaches for sustainable
agriculture.
