ecause pollen loses viability and significantly reduce the production of grain and seeds, and sunflowers oil percentage. Average number of days at all stations, with temperatures above 30 0 C were 16.33 days in 2008, 58.04 days in 2009, 47.8 days in 2010 to 53.96 days in 2011. These days occurred in 20-25% since June, but the majority of the days in July and August. Amplitudes temperatures above 30 0 C during the day and below 10 0 C at night, that occur during flowering and grain filling, prevents anther, pollen default development and the normal process of fecundation. Thermal shock after fecundations disturb accumulation of reserve substances in beans and corn shrivelled phenomenon occurs. Amplitude of high temperatures adversely affect crops in the summer months, June-July- August and vegetation phases of flowering and grain formation, when droughts are most common, soil moisture is very poor. Maximum amplitude of temperature is recorded on a station located on a southern slope – Filpisu Mare, in the southeastern part of the Transylvanian Plain, where there were differences between high and low in the following days: 28 June 2009, 9.83-47.97 0 C (38.14 0 C); 7 July 2010, 13.74-48.44 0 C (34.7 0 C); 1 June 2011, 11.3-49.31 0 C (38.01 0 C). Brani? tea station on a slope which faces west, representative of the northern and northwestern Transylvania Plain maximum thermal amplitude recorded in 24 hours, was: 15 June 2009, 7.98-42.4 0 C (34.42 0 C); 7 June 2010, 10.36-41.23 0 C (20.87 0 C); 22 August 2011, 8.58-42.16 0 C (33.58 0 C). Figure 2. Days with droughts recorded during 2009-2011 CONCLUSIONS After analyzing the recorded data, thermic and hydric, in the Transylvanian Plain, we recommend as optimal sowing period, advancing those known in the literature, with 5 days for corn and soybeans, and maintaining the same optimum period for sunflower and sugar beet, thus: Corn: 5 to 25 April; sunflower: March 25 to April 10, sugar beet: March 20 to April 10; soybean: April 5 to 15. Great differences are recorded from one station to another, the results are influenced by soil type and its exhibition, so in practice it is very important to take into account the differences in slope morphology. For crop growing season of spring (April to October) southern, southeastern and eastern slopes have lower precipitation with approx. 43.8 mm, higher temperatures with 0.37 0 C in air, with 1.91 0 C at 10 cm in soil, with 2.22 0 C at 20 cm and with 2.43 0 C at 30 cm depth in soil, compared to northern, north-western and western slopes. Water requirements are provided in an optimum, of 58.8 to 62.1% for the spring 117
weeding crops during the growing season, thus irrigation is necessary to ensure optimum production potential. Droughts are recorded in June-July-August, in a total of 36 (Branistea, 2009)-83 (Dipsa, 2011) droughts days, overlapping temperatures above 30 0 C, between 47.8 – 58.04 days, during 2008-2012. The amount of biological active degrees registered in Transylvanian Plain shows the necessity to reconstruct crop zoning, known in the literature, for the analyzed crops: wheat, corn, soy, sunflower and sugar beet, ensuring higher levels for their zoning, respectively the possibility of cultivation of varieties/hybrids semi late or late in a higher percentage.
