In this study, two hydroponic experiments were conducted in nutrient solution growth system. Experiments were conducted in growth chamber of Erciyes University, Agricultural Faculty in Kayseri, Turkey. In the first experiment, 10 local Turkish bottle gourd genotypes and two commercial watermelon cultivars were screened under 2 N doses (0.3 mM and 3.0 mM N) in RBD design with three replications for six weeks. In the second experiment, four genotypes (N-efficient: 70-07 and 07-45, N-inefficient: 35-10 and 45-07) were selected and used as rootstock for grafting with N-inefficient watermelon cultivar (Crimson Sweet) under 2 N doses. The grafted N-efficient gourd genotypes (07-45 and 70-07) significantly contributed to growth and biomass production of the N-inefficient watermelon plants as compared to non-grafted control plants and thus showed a higher rootstock potential for watermelon. The N-efficiency of some gourd genotypes was associated with vigor root growth and active root system particularly at low N conditions. These traits could be useful characters to select ‘N-efficient’ bottle gourd rootstocks for sustainable agriculture in the future.

As opposed to direct sowing, production of seedlings of vegetable crops for transplanting is commonly practiced by vegetable growers. This study was undertaken to determine the effects of humic acid on the growth and the macro and micro nutrients contents in tomato (<i>Lycopersicon esculentum</i>) and eggplant (<i>Solanum melongena</i> var. <i>esculentum</i>) seedlings under greenhouse conditions. Different levels of humic acid (50, 100, 150, 200 ml l<sup>-1</sup>) were applied to growing media (peat) after transplanting of examined seedlings of the species every ten days by the time of planting. The highest growth rate for leaf stem and root growth were obtained at 50 and 100 ml l<sup>-1</sup> HA and 50, 100, 150 ml l<sup>-1</sup> HA for tomato and eggplant seedlings., respectively as compared to the control. The highest content of macro and micronu trient contents were obtained at 100 ml l<sup>-1</sup> HA and 200 ml l<sup>-1</sup> HA for tomato and egg plant seedlings, respectively as compared to the control.

In this paper, tests were carried out with four agricultural mulching films used commonly in Microstructure observations of electron microscope, FTIR spectral analyses, and rice seed growth characteristics testing respectively. PLA non-woven was selected out as the inclusive material for the rice seed tape with the advantages of easy degradation, environmental pollution free, less impact on germination rate and the plant height of rice seed. The results will provide practical significance for the application of the rice direct sowing technology with seed tape.
