Impact of green manure and intercropping in organic greenhouse tomato
<p>Test the impact of green manure and intercropping with legumes inoculated or non-inoculated with rhizobia and endophytic bacteria on nitrogen, phosphorus and potassium nutrition in organic greenhouse tomato.<br> The first experiment (GE1E1) started on May 23rd 2017 and was terminated on January 19th 2018; the second experiment (GE1E2) started on February 8th and was terminated on June 11th 2018; the third experiment (GE1E3) started on June 12th 2018 and was terminated on January 30th 2019. In 1st experiment (GE1E1), self-rooted plants of the commercial tomato hybrid ‘Elpida F1’ were cultivated, while in 2nd and 3nd experiment (GE1E2 and GE1E3, respectively), the commercial tomato hybrids ‘Ekstasis F1’ and ‘Elpida F1’, respectively, grafted onto the commercial rootstock ‘Maxifort F1’ were cultivated. The plant density was 2.13 plants/m2 in all experiments of GE1.<br> In GE1E1 and GE1E3 (tomato crops established in August and terminated in January), summer-grown cowpea was applied as green manure before establishment of the tomato crop, in order to be tested as a source of nitrogen in addition to farmyard manure (FYM). The treatments were identical in both GE1E1 and GE1E3. More specifically, in treatment 1 (CON), which was considered as control, no other source of N was applied except for FYM. In treatments 2 (GM-C), 3 (GM-C+BV) and 4 (GM-C+BV+EB), additional N was provided through green manure, by sowing cowpea (<em>Vigna unguiculata </em>(L) Walp.) and incorporating the plants at anthesis into the soil, shortly before planting the tomato crop. However, in GM-C the seeds of cowpea were not inoculated with any rhizobia, while in GM-C+BV the cowpea seeds were inoculated with<em> Bradyrhizobium sp</em>. VULI11 (BV) (Tampakaki et al. 2017), and in GM-C+BV+EB the seeds of cowpea were inoculated with a mix of BV and endophytic bacteria.</p>
Comparison of compost or green manure with farmyard manure for fertilizing organic greenhouse tomato
<p>The 2nd group of experiments (GE2) included two successive tomato experiments. The first experiment (GE2E1) started on May 23rd 2017 and was terminated on January 19th 2018; the second experiment (GE2E2) started on February 8th and was terminated in on June 11th 2018. In the 1st experiment (GE2E1) the commercial tomato hybrid ‘Elpida F1’ grafted onto the commercial rootstock ‘Arazi F1’ was cultivated, while in the 2nd experiment (GE2E2) the commercial tomato hybrid ‘Ekstasis F1’ grafted onto the commercial rootstock ‘Maxifort F1’ was cultivated. The plant density was 1.07 plants m-2 in GE2E1 and 2.13 plants m-2 in GE2E2 but the plants in the GE2E1 were pruned into two stems and thus the stem density was identical in both experiments (2.13 plants m-2).<br> The GE2 was designed to assess the efficiency of compost, or green manure using legume crops inoculated with rhizobia, as sole sources of nitrogen in organic greenhouse crops of tomato in comparison with FYM. Therefore, in GE2, FYM (the same source and amount as in GE1) was applied only in treatment 1 (T1) which was considered the control treatment.</p>
