Influence of humic acid, compost and mineral –N on nutrients availability, yield quality and chemical composition of peanut in sandy soil
Abstract: : Soil amendments efficiently improves soil fertility and crop productivity, especially poorly fertile sandy soil. This study was conducted during summer 2012 and 2013 seasons, at Ismailia Agriculture Station Research, Ismailia Governorate, Egypt. To study the effect of organic and inorganic nitrogen forms at three N rates, i.e. 15, 25 and 40 kg N fed-1 ; humic acid (0, 5 and 10 kg fed-1) and (0 and 10 Mg fed-1) compost on sandy soil content nutrients availability, yield, oil (%), protein (%) content as well as nutrients content of peanut plants. Peanut (Arachis hypogaea L.) Varity Giza 6 was use in the study as treated plants. The results showed that soil treated with humic acid combined with mineral nitrogen at rate of 40 kg N fed-1 in the presence of compost showed an increase in available N, P and K in compared with soil without compost. Relative increases in mean values of Fe, Mn and Zn were soil found in the pots treated with humic acid combined with mineral nitrogen without compost in the first season, while the mean value of Mn was increased with the soil treated with humic acid combined with mineral nitrogen and compost in second seasons. Increase in pod yield (Mg fed-1); seed yield (Mg fed-1) and 100 grain weight (g) in the second season was noticed with the plots treated with humic acid combined with mineral nitrogen and compost compared with the other treatments. The concentration of N, P and K by peanut seeds significantly increased amounted due to soil addition of humic acid combined with mineral nitrogen and compost compared with the other treatments. Concerning the oil (%) concentration of peanut seeds, results showed no significantly differences in both seasons as affected by all treatments without compost. Humic acid application and mineral nitrogen rates with or without compost significantly affected on Mn and Zn concentration in peanut seeds plants were significantly in both seasons, while the Fe concentration was not significantly affected in first season
