Response Ofyield And Quality Of Two Groundnut (Arachis Hypogaea L.) Cultivars To Foliar Applicationwith Some Micronutrients In Newly Reclaimed Sandy Soil
: Groundnut, Foliar application, Yield and yield attributes, Amino and fatty acid composition
Two field experiments were carried out during two summer successive seasons (2016 and 2017) at the Production and Research Station, National Research Centre, El- Nubaria Province, El-Beheira Governorate, Egypt to investigate the response of two groundnut (Giza 6 and Gregory) cultivars to some micronutrients foliar application (Zinc, Manganese, Boron and their combinations) at different growth samples (75 and 90 days of sowing) (DAS) on yield, yield attributes and chemical characters of seeds under reclaimed sandy soil condition. The experimental design of this investigation was laid out in split-plots design with four replicates, where cultivars were assigned in the main plots and micronutrients foliar application with Zn, Mn, and B were randomly distributed in the sub-plots. The results recorded significant differences on most of studied characters i.e. growth, yield and yield attributes affected by cultivars differences and micronutrients foliar spraying treatments. Giza 6 and Gregory cultivars show highly significant differences at 75 and 90 DAS, however, Giza 6 surpassed Gregory cultivar in most of studied characters at two growth samples except, plant height at 75 DAS. Applying the thrice micronutrient foliar application (Zn+ Mn + B) records the highest values of most studied characters except, number of branches plant-1 in both growth samples. The interaction between groundnut cultivars (Giza 6 and Gregory) and micronutrient foliar application showed the highest values of fresh weight plant-1 (g) and dry weight plant-1 (g) on intervals 75 and 90 DAS. On the other side, groundnut cultivars differed on macro and micro nutrients seed content, Giza 6 surpassed over Gregory cultivar in macronutrients (N, P and K % seed content) that recorded a high mean values 4.18, 0.82 and 0.62 % for N, P and K % seed content, respectively, comparing with Gregory cultivarwhich recorded 3.84, 0.73 and 0.53 % for N, P and K % seed content, respectively. Groundnut cultivars cleared variation for protein and oil seed content %, the mean value of seed protein content by Giza 6 cultivar which recorded 26.0 % surpassed over Gregory cultivar 23.99 %. On contrary, seed oil content of Gregory cultivar records a high mean value 45.92 % comparing with Giza 6 cultivar 42.63 %. Saturated amino acid profile of seed protein indicated that Lucine and Phenylalanine acids were the major content of essential amino acid in the seed protein content %. The data of interaction between groundnut cultivars and micronutrient foliar application on essential amino acids composition revealed that Giza 6 surpassed over Gregory cultivars in most essential amino acid composition except Lysine acid. The highest values of non-essential amino acid profile were observed in Aspartic, Glutamic and Argnine that recorded 4.16, 7.61 and 4.66 mg/g dry weight, respectively. Fatty acids profile illustrated that saturated fatty acids and unsaturated fatty acids affected slightly by micronutrients foliar application treatment and groundnut cultivars. Generally, this investigation illustrated that Giza6 cultivar was recorded a higher attitude of most growth, yield and yield attributes as well as chemical seed composition characters by some micronutrients foliar spraying application and their combinations under reclaimed sandy soils.
