Abstract: It is difficult to establish any agronomic practice programs for wheat (Triticum durum L.) production in Kurdistan region because of unpredictable variation in rainfall. Both of seeding rate and seeding depths are important aspects of management since they can be controlled practically. This study was conducted for two basic purposes 1st...

In two stages (30-45 DAS and 45-60 DAS), the study assessed the growth of cowpeas and sunflowers in Qushtappa and Ankawa under various intercropping ratios (4SF:1CP, 4SF:2CP, 4SF:3CP, and 4SF:4CP) and cover types (exposed or mulched). The results indicated that locations, cover types, and intercropping ratios had a substantial impact. With more mai...

This experiment was conducted at Grdarasha Experimental Field, University of Salaheddin, Erbil (36.11 o N, 44.01 o E), to study the growth performance of cotton cultivar Coker 310 under four micro environmental conditions. The levels were composed of row directions and sowing dates as main plot (E1-E4) in split plot of Randomized Complete Block Des...

Nelder fan design is to study several plant densities in the smallest area , as planting of the same number of seeds is done on different circumferences of concentric circles .

Some crops perform better in intercropping systems with other crops relative to their solcropping. Sunflower (Helianthus annuus L.) was adopted to be studied in a field experiment within an additive intercropping system with mungbean (Vigna radiata L.) in a three rows in combinations (1:3 and 1:4 and 1:5) sunflower-Mung bean intercropped and sole c...

Two of newly registries of Italian durum wheat cultivars (L 992 and L 430) were grown to compare with Acsad 65 durum wheat cultivar .The cultivars were planted in seven plant densities in fan design at 2008-2009 growing season to search the possibility of their introducing to Erbil. This effort comes through the scientific corporation between Salah...

Three different wheat and triticale genotypes (two wheats; CYMMIT and Aras, and one triticale Rwaida) were evaluated under five late sowing dates at Einkawa farm of Erbil Dry-land Research Center, KRG-Iraq (Lat 35 0 0 0 38 00 N Long 43 0 0 0 24 00 E) for two growing seasons 2015-2016 and 2016-2017 to test any agronomic variance characteristics as a...

The study was conducted to investigate the effects of winter crops succession on maize growth and productivity, at Salahaddin University, Erbil, Iraq, during fall and a winter season of 2016-2017. During both fall seasons, the field was completely planted with maize, afterwards, at winter season, three crops were selected namely canola, chickpea an...

Purpose: The study aimed at assessing the effects of maize-alfalfa intercropping with and without nitrogen fertilization on photosynthetic characteristics, photosynthetic nitrogen utilization efficiency (PNUE) and yield. Methods: A 2-year field experiment with split plot arrangements was conducted to study the effect of different planting patterns...

Abstract A field experiment was conducted at Grdarasha Experimental Farm / College of Agricultural Engineering Sciences / Salahaddin University – Erbil, located at (36.2o N, 44.1o E and elevation 470 m) during the winter season of (2016-2017) to study the performance of wheat (Triticum aestivum L.), chickpea (Cicer arietinum L.) and wild mustard (S...

about crop succession

Self-thinning is a natural phenomenon behaved by biological population , my opinion is that death toll due to corona is restricted by this phenomenon .

Population self-thinning as described by Kiera et al 1953 , might be applied to human population also . it is just an effort to see the applicability of this phenomenon to humanity . this issue is an addition to the previous one .

The third update of Corona self thinning is updated at 2 May 2020 as an attempt to forecast the behavior of the virus , the previous three versions were about weekly death and infected population , this version jumps to monthly effect , and will be updated each 30 days intervals .

log of individual plant mass (tolerated to number of corona virus infected ) displayed against log density for various times after emergence (tolerated to death toll) . the course of log death along the -3/2 limit.

A field experiment was carried out on inter-cropping of wheat (Triticum aestivum L.), chickpea (Cicer arietinum L.), and wild mustard (Sinapis arvensis L.). Treatments from combinations of either single, double or triple (row: crop) proportions were arranged in the standard replacement series at Grdarasha experimental farm (36.2º N, 44.1º E, and el...

Growth analysis of three inter-cropped genotypes

This investigation was conducted to understand the response of three newly introduced bread wheat cultivars to Erbil area (V1: FLORKWA, V2: BAJ and V3: FRANKOLIN) to three boron levels sprayed at elongation stage 0, 1 and 1.5 ppm concentration and oriented (South-North and East-West) row directions to study the vegetative and reproductive growth ch...

Abstract: Eight of barley pedigrees where compared to one six row adapted cultivar Acsad 12 and another six row adapted cultivar Acsad 14 in an field experiment at two locations of Erbil province (Einkawa and Koya) for three barley growth seasons during the period of 1993 – 1996, resulted in different effects on vegetative and reproductive growth i...

Utilizing of new models to predict wheat yield losses due to weed competition

Comparison among some new wheat varieties and a locally adapted best performance adapted durum wheat Acsad 65 . using Fan design (Nelder 1960) to minimize number of required plots which serves as increasing of plant density and row direction .

ABSTRACT This research was conducted at Girdarasha – experimental station /college of agriculture, University of Salahaddin .during the growing season of 2008 – 2009 to study some growth, yield component, yield and quality of intercropped wheat and lentil.
