Abstract
The present work aimed to study the effects of planting dates and foliar applications of Humic and Gebbrillic acids on growth, yield components and yield of three commonly cultivated Jew’s Mallow (Chorcorusolitorius L.) ecotypes. Field experiments were conducted in 2015 and 2016 cropping seasons at the Vegetable Crops Research Station, Faculty of Agriculture, Assiut University, to study the response of three Jew’s Mallow Ecotypes (Assiut, Eskandarany and Aswan) to planting dates and foliar application of Gibberellic (GA3) and Humic acid (HA) treatments. The Jew’s Mallow Ecotypes were planted in 15th Oct and 15th Feb. in both cropping seasons and subjected to 3 foliar applications of 0.25ml.l-1 GA3 (T1), 0.5ml.l-1 HA (T2) and 0.5ml.l-1 HA + 0.25ml.l-1 GA3 (T3). The experiments were laid out in Split Plot Design using 3 replicates. There were significant differences due to Jew’s Mallow Ecotypes (GME), planting dates (PD), Growth hormones (GH) and their interactions except the triple interaction (JME*PD*GH) for all investigated parameters. The results revealed that the Jew’s Mallow ecotype ‘Assiut’ attained the highest plant stem(cm), no. of leaves/plant, weight of leaves/plant(g), weight of plant (g), % net weight of leaves/plant and foliage yield (kg/plot) in both seasons. The late planting date (15 Feb) extremely increased growth, yield components and yield parameters in 2015 and 2016. Foliar application of Gibberellic acid (GA3) at 0.25mgl-1 (T1) significantly increased growth and yield of Jew’s Mallow plants. Spraying plants of the Jew’s Mallow ecotype ‘Assiut’ with GA3 at 0.25 ml.l-1 at planting date 15 Feb. significantly increased growth, yield components and yield parameters in both seasons.
