| ABSTRACT Potassium (K) influences the variables that determine quality of fruit and the concentration of phytonutrients to human health and therefore consumer preferences. The objective of this study was to evaluate the effect of different concentrations of K in the nutrient solution (5, 7, 9 and 11 mM of K) on yield and quality of Cantaloupe fruits under greenhouse conditions. The experiment was conducted in pots using a completely randomized design with 15 replications. Analysis of variance, correlation, regression and multiple comparisons among means (Tukey p<0.05) were performed. Results showed higher values of yield, average fruit weight, equatorial diameter, pulp thickness, fruit firmness, soluble solids content, phenolic content and antioxidant... |

| ABSTRACT The objective of this study was to compute and compare DRIS norms for grafted and non-grafted red bell pepper crops grown in semi arid climate conditions. DRIS norms were computed with 84 samples of first young mature leaves collected during developed stage. The experiment had a completely randomized block design, and the values obtained for each plant and each variable were considered as independent replicates. Thirty-two DRIS norms nutrient ratios and coefficients of variation (CV) were computed from N, P, K, Ca, Mg, Fe, Cu, Zn and Mn analytical results. The ratios P/N and K/N in grafted and non-grafted pepper plants, showed low CV and therefore may play a fundamental role in crop production according with the DRIS norms calculated, since as... |

| ABSTRACT Yield and nutraceutical quality of Sahel tomato cultivar under shade net was evaluated using different mixtures of organic substrates in Coahuila, northern Mexico. The treatments consisted of mixtures using sand (S), vermicompost (VC), solarized bovine manure (SB), agricultural soil (AS) and mineralized compost (MC). The treatments were: T1 (S:VC, 80:20), T2 (S:SB, 80:20), T3 (S:SB:AS, 80:15:05), T4 (S:VC:AS, 80:15:05), T5 (S:MC, 80:20), and a control treatment T6 (S, 100%) with Steiner solution. Yield results showed that the best organic treatments were T5 and T4 with 3.48 and 3.33 kg plant-1, respectively; while the highest yield was in control (T6) with 3.71 kg plant-1. The highest phenolic content in the organic treatment of fruits was 56.94... |
