Influence of different types and rates of organic fertilizers application for improv1ng some properties of salt affected soils and maize productivity
Abstract: Two field experiments were conducted during two successive summer seasons 2012 and 2013 on a clay soil at El-Serw Agricultural Research Station, Agricultural Research Center, Egypt. .The experiments were carried out in a randomized complete blocks design with three replicates to study effect of different types and rates of organic fertilizers which can be applied to improve some properties of salt affected soils and its productivity of maize, i.e. Poultry manure, compost and farmyard manure at the rate of (0-24-48 Mg ha-1). at three different locations in salinity levels. The results showed that the chemical and physical properties of the studied soil were clearly improved due to organic fertilizers addition. The common parameters of salt affected soils i.e., increased hydraulic conductivity (Ks),organic matter( O.M) and grain yield .On the contrary, bulk density, Penetration resistance (P.R.), pH, EC, and ESP values were decreased. . The superior improvement of these parameters was resulted from T6, T5 andT4. The amendments can be arranged, ascending as follows:
T0 Also, the growth traits i.e. Plant height, dry weight, grain yield, stover yield, N, P, K-uptake in both grains and stover of maize plant at harvesting stage significantly decreased drastically with increasing salinity levels in both two seasons as a result of salinity stress. On the contrary, previous parameters significantly increased with organic fertilization application at harvesting stage in 1st and 2nd seasons.. The highest values were obtained with low soil salinity levels + 48 Mg ha-1 poultry manure. Similar trend was found throughout the three locations
