| Abstract | ||
| Two experiments wereperformed in 2019 and 2020 to study the effect of the irrigation levels and organic amendmentson nutrientavailability and peanut productivityAmendmentsas ton/fed were 5 tons of compost, 5 tons of farmyard manure and 50 kg/fed of humic acid. Irrigation as m3/fed were 1652, 2203 and 2754 in the first season but were 1555, 2074 and 2592 in the second one as 60, 80 and 100 % of ETc. respectively. Higher availabilityof N, P, K, Fe, Mn and Zn occurred in farmyard manuredsoils under irrigation rates comparing with other organic amendments. Increasingirrigation water increased available N and Mn in the soil, but was not significant for P, K, Fe and Zn. All used organic amendments caused a significant increase in growth parameters and productivity. The highest growth parameters and productivity were associatedwith composttreatment with all rates of irrigation compared with other treatments of organic amendments. Growth parameters were notaffectedbyirrigation ratesexcept for branched plants. The interaction between irrigation rates and organic amendments were significant for growth parameters. Adding organic amendments with and without irrigation water rates increased N, P, K, Fe, Mn and Zn concentrations in the seeds, while the high increases were found with compost combined with different rates comparing with other treatments of organic amendments. The effect of irrigation rates on nutrients concentration in the seeds was not significant except when organic amendments was applied. | ||
