| ABSTRACT This study aimed to evaluate NPK formulations used in fertilization at sowing associated with and without humic substances (HS) in terms of the agronomic characteristics and grain quality for malt from the barley cultivars BRS Brau and BRS Elis, focusing on the agricultural years 2015 and 2016 in Guarapuava, PR. The experimental design was a randomized block, in a factorial 5 x 2 format, with five fertilizations: 0 kg ha-1 (control); 100 kg ha-1 of NPK; 100 kg ha-1 NPK + HS; 250 kg ha-1 of NPK; and 250 kg ha-1 NPK + HS, using two barley cultivars, BRS Brau and BRS Elis, replicated four times. The variables evaluated were hectoliter weight, grain yield, malt quality by means of sort 1, 2 and 3, and the protein percentage. The data evaluated were... |

| ABSTRACT This work aimed to evaluate extraction/ export of nutrients and dry matter production in the 'Gigante' cactus pear, grown in different spacings and fertilizations 620 days after planting. Twelve combination of treatments were used consisting of: three spacings - 1.00 x 0.50; 2.00 x 0.25; and 3.00 x 1.00 x 0.25 m, and four fertilizations - 000-000-000; 000-150-000; 200-150-000; and 200-150-100, kg ha-1, of N, P2O5 and K2O, in a 3 x 4 factorial scheme in a randomized block design, with three replicates. Extraction/export of N, P, K, S, Ca, Mg, B, Fe, Mn, Zn, Na and Cu were determined and the means were 304.35; 18.81; 421.04; 62.35; 464.63; 215.77; 0.39; 0.81; 23.74; 1.11; 0.62 and 0.08 kg ha-1, besides the mean dry matter production of 17.11 Mg... |

| A field experiment was carried out in Kafer El Kadera village at El–Monofia Governorate, during 5 consecutive years, 2010–2014, to test the effects of NPK and balanced fertilization on the yield and its components, and distribution of nutrients in different parts of maize (var.30K8).There was a significant increase of the number of leaves/plant, the length of cob, the number of rows in the cob and the number of grains in the row as a result of treated plants with NPK according to soil testing plus foliar application of micronutrients by 34.18, 27.94, 32.182, and 33.43%, respectively.There was also a significant increase in the chilling % rate, weight of 100 grains and yield of grain / plant, yield /ton/ha by 16.52, 35.39, 68.40, and 72.92%,... |
