Abstract

Drip irrigation and mulch is the best methods for increasing in cotton yield. A field experiment was implemented at the Research Station of AL-Hasaka governorate through 2011/2012, using randomized complete block design containing three levels of irrigation: the first treatment (A) was to irrigate 100% of water requirement, when the soil moisture went down to 80% of field capacity, with  sufficient quantity of water to raise the soil moisture to field capacity, and the second  treatment  (B) was irrigated at the same time of (A) treatment, but with 75% of the quantity of A, and the third treatment (C) was also at the same irrigation time, but with half the quantity of (A). Four methods of covering was adopted; drip irrigation without mulching, drip irrigation with white, black plastic film and straw cover as Mulch, with three replicates. The goal of the research was studying the effect of mulch on soil moisture and salinity of the soil profile of cotton, the distance was 35 cm, 17.5 cm, under the drop pipe and its effects on production. The results showed that in mulch condition the soil moisture did not differ all over the pipe, contrary to drip irrigation without mulching treatment in which the soil moisture was higher under drop pipe particularly, while the soil moisture decreased whenever the distance went away from the pipe. Salinity of soil rised whenever soil moisture decreased. Concentration of soil salinity increased in upper section (0-30 cm) in low irrigation treatment (C) and drip irrigation without mulching treatment compared with mulching treatment. So, the production varied between 1019-7081 kg/ha for straw mulch under 50% moisture and white mulch with 100% moisture respectively.

Abstract

This search was carried out at Tizen Station, Hama Agriculture Research Center, during 2011 and 2012 seasons. The aim of this study is to improve water efficiency and to determine the critical stage for peanut under different levels of irrigation and to study the effect of irrigation levels on yield. Complete randomized block design with four replicates was used. Four treatments of irrigation were applied, the first level (A 100%) was applied when the soil humidity was 75 % of field capacity. At the second level (B) the irrigation was done at 75 % of level A, while at the level C the irrigation was done at 50% of level A, and at the level D the irrigation was done at 25 % of level A. Drip irrigation was used and the irrigation control depended on the differences  of soil moisture by using Neutron Brobe. The values of ETO were calculated depending on meteo data of climatic station. The results indicated that the level A was superior to other levels in yield (3.643 ton/ha), but the best level in water efficiency and yield was level B (0.72 kg/m3, and 2.153 ton/ha), also the water requirement of this level was 2639 m3/ha.

Abstract

Drip irrigation is the best method for increasing cotton yield. A field experiment was implemented during 2011 season, at the Research Station of AL- Hasaka Agricultural Research Centre, General Commission for Scientific Agricultural Research Center (GCSAR)/Syria, using randomized complete block design arranged in split plots. Three levels of irrigation were used: The first treatment (A) is to add 100% of water requirement, when the soil moisture is 80% of field capacity, the treatment (B) is to be irrigated with 75% of the water requirement, and the treatment (C) is to be irrigated with half amount of (A). Also three methods of soil coverage were adopted, without mulching, cover with black plastic, and white film cover as mulch, with three replicates. The goal of study was to evaluate the response of cotton variety Aleppo 90, to different levels of drip irrigation, and different soil mulching, and to determine water requirement. The results showed a high significant superiority (P<0.005) of treatment (A) compared to (B) and (C) treatments, while according to mulching levels; the white plastic mulch surpassed the other treatments. The saving percentage of water in drip irrigation with white, and black plastic films were (25, and 18)%  respectively, compared with drip irrigation without cover.

Abstract

The study was carried out in Mokhtaria Research Station, Homs Agricultural Research Center, General Commission for Scientific Agricultural Research Center, Homs, Syria, during 2008-2009 and 2009-2010 seasons. Two methods of drip irrigation were applied (mulched, without mulch) on tomato crop to be compared with the traditional method (surface irrigation). The results showed that the average of the total water consumption for the drip irrigation (mulched) was 3345 m3/ha and percentage of saving water irrigation was 55% as compared with control (traditional surface irrigation), while the average of the total water consumption for the drip irrigation (without mulch) was 3785 m3/ha and percentage of the saving water irrigation was 49% as compared with control, although the average of the total water consumption for the traditional surface irrigation was 7426 m3/ha. In terms of farming method (traditional and organic) the production under drip irrigation (mulched) were 29.7 and 38.4 ton/ha, with an increment in yield of (60 and 68%) as compared with the control (surface irrigation) which were 18.6 and 22.9 ton/ha (traditional and organic), respectively. On the other hand the production under drip irrigation (without mulch), in terms of farming method (traditional and organic) were 38.4 and 45.1ton/ha with an increase in yield 106 and 97%, respectively as compared with the control.
