Abstract
Salinity becomes one of the most important and serious agricultural problems. Furthermore, it is an ever-present impendence to crop productivity, especially in the countries where irrigation is a determining factor for agricultural activity. It is known that crop matching is one of the ways to overcome the problem of soil salinity, such as triticale plant which was recognized as a crop suitable for growth in saline soils. Two field trials were conducted to study the interaction effect of soil salinity levels, Humic substances and mineral phosphorus fertilization, it can further illustrate how triticale cultivation in saline soils is developed by studying the impact on plant height, forage fresh and dry weight, total NPK uptake in dry forage. All privies parameters were depressed with increased salinity levels. While the order of Humic substances for their influences on triticale growth parameters and total N, P and K uptake were as follows: Falvic soil, Falvic foliar, Humic soil, Humic foliar, without Humic substances. While, applying 140 kg P ha-1 gave the highest results of previous parameters. While the interaction effect shows that when using 70 kg p ha-1 in low soil salinity (SL), or when using 140 kg p ha-1 in moderate soil salinity (SM), the effect of Humic substances will become clear on fresh and dry forage yield and total N, P and K uptake of triticale. Therefore, it is preferred that applying Humic substances and mineral phosphorus fertilization to the improvement of triticale production with increasing soil salinity.
