Abstract:
Little work has been done on potassium (K)
and zinc (Zn) in combination with farm yard manure (FYM) under rainfed
conditions of NWFP. This study was designed to examine the effects of
un-irrigated cropping patterns and organic and in-organic fertilizers on
wheat crop. Field experiments were conducted to investigate the effect
of cropping patterns and farm yard manure, potassium and zinc on
phenology and grain yield of wheat under rainfed (barani or
un-irrigated) conditions at Agricultural Research Station, Serai Naurang
Bannu for two years during 2001-02 and 2002-03. The experiment was
designed in RCB design with split arrangements. Two factors were studied
in the experiment. Effects of five cropping patterns i.e., fallow-wheat,
groundnut-wheat, mungbean-wheat, sorghum-wheat & pigeon pea-wheat and
three organic and in-organic fertilizers on subsequent wheat crop were
observed. Data revealed that both the cropping patterns and
manures/fertilizers had non-significant effect on days to anthesis, seed
fill duration and days to maturity of wheat. Highest grain yield (3194
kg ha-1) was produced by wheat fallowing mungbean. Based on
two years average, it is concluded that wheat following mungbean
produced more yield and wheat following groundnut produced less yield
under dryland conditions. The present findings revealed that pigeon
pea-wheat cropping pattern seems to be more sustainable in terms of
yield under rainfed conditions and use of FYM, K and Zn should be
included in integrated crop management approaches for sustainable crop
production.
