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.

Alternative approach to mitigate the negative consequences of aluminium toxicity on cowpea Vigna unguiculata (L.) Walp. (Fabales: Fabaceae) productivity cannot be overemphasized. The effects of aluminium toxicity on some morphological parameters of five cowpea accessions were investigated with the aim of determining the threshold of tolerance for the crop. Five cowpea accessions were collected from the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria. The seedlings were raised in perforated plastic pots filled with 10 kg of top soil and treated till maturity with 50 µm, 100 µm, 200 µm of AlCl3 while those irrigated with tap water served as the control (0 µm). Variations were observed among accessions and treatments as plant height was accession dependent in contrast to stem girth, number of branches, root growth and shoot growth. Suppression of root growth among the accessions were attributed to more carbon allocation to the shoot at the expense of shoot growth leading to chlorosis, necrosis and reduced photosynthetic capacity among the accessions. Accession 5 was adjudged the best among the accessions based on the response to aluminium treatment. However, further research on the mechanism of tolerance especially at the molecular level is highly recommended.

Plant Growth Characteristics

Plant growth characteristics were observed for 12 morphotypes of Corchorus olitorius planted in the field. Two commonly used varieties in Nigeria were subjected to increasing nitrogen fertilizer rates. Extensive variations in measured leaf, stem, and root growth confirmed genetic diversity among morphotypes. Thus, fresh shoot harvest l00 kg N/ha at 3 kg/ha seed rate for the lanceolate was 17.44 t·ha–1, the serrate-type at the same seed rate required N at 200 kg·ha–1 to produce 18.19-ha harvest.
