Field investigations were conducted during the winter seasons of 1992/93 and 1993/94 to find the optimum sowing time and time of last fodder cut for the fodder and seed production of Egyptian clover (Trifolium alexandrinum L.). The delay in sowing from 1 October to 15 November decreased the green and dry fodder yields but increased the seed yields. Total green and dry fodder yields (of all cuttings) for 1 or 15 October sowings were significantly higher than the 15 November sowing in both years and 1 November sowing in 1992/93. Increase in seed yield from the 15 November sowing was greater than from the 1 and 15 October sowings. Straw yields followed similar trends. Delay in the last cut for fodder, however, increased green and dry fodder yields but decreased the seed yield. The percentage increase in dry fodder yield with each successive delay in last cut for fodder was higher than that of green fodder yield. The 11 April cutting date of fodder produced the highest green and dry fodder yields but the lowest seed yield. Two years mean data showed that the 2 March cutting date of last fodder gave the highest seed yield. It is concluded that higher seed yield of Egyptian clover can be produced by sowing on 15 November and giving the last fodder cutting on 2 March.

Field Germination

A characteristic property of legumes is the formation of hard-stone seeds. To use such seeds for sowing, it is necessary to carry out measures to increase their seeding indicators. The article provides an overview of methods of pre-sowing preparation of seeds, priming (Seed Priming). The harvest of Birdsfoot trefoil (Lotus corniculatus L.) can contain up to 90% or more hard-stone seeds. Mechanical priming of hard-stone seeds of Birdsfoot trefoil increases their germination energy and field germination.

В статье описаны симптомы поражения семенных растений редиса A. candida, дана оценка ряда сортов с разной устойчивостью к A. candida. Описаны способы борьбы с этим заболеванием при элитном семеноводстве редиса. В результате двулетней оценки образцов питомника размножения выявлено, что есть сортовая специфика устойчивости к Albugo candida. Более склонен к поражению в генеративную фазу развития сорт Кармен, наиболее устойчив к патогену сорт Меркадо.The symptoms of A. candida on seed plants radish are described a number of varieties with different resistance to A. candida are evaluated. The methods of combating of this disease in elite seed production of radish are described. As a result of twoyear evaluation of breeding nursery samples it was revealed that there is varietal specificity of resistance to A. candida. The Carmen cultivar is more prone to disease in the generative phase, the most resistant to the pathogen is Mercado cultivar.
