In order to study the effect of the superabsorbent polymer and manure fertilizer on the baking characteristics of wheat cultivars under different water deficit conditions, an experiment was carried out in a factorial layout based on a randomized complete block design in three replications at Agricultural Research Center, West-Azerbaijan (Saatlo station) during 2017-2018 growing seasons. The fac...
Yield is a quantitative trait and improving grain yield through direct selection is time-consuming. Indirect selection consisting of selection indices is more promising. A field experiment was conducted during 1999-2000 growing season in two experimental locations (Kooshkak and Badjgah) of College of Agriculture, Shiraz University, Shiraz. Thirteen corn hybrids were used in a randomized complet...
Chickpea (Cicer arietinum L.) is a native crop of Asia which is grown worldwide including Iran.In this study,different selection criteria including correlation,regression and path analysis were used to improve yield.The experimental design was split plot with RCBD replicated four times in which three sowing dates (5 January,4 February,and 5 March) were used in main plots and four genotypes;two ...
a pot experiment was designed to evaluate the effect of trichoderma spp. on yield and yield components of wheat (cv. n81) under different levels of cadmium nitrate. experiment was arranged in factorial based on completely randomized design with three replicates. trichoderma harzianum at two levels (with and without inoculation) and four levels of cadmium nitrate (0, 50, 100, 150 mg l-1) were th...
In order to determine the most effective indices for quantifying drought tolerance and identify genotypes that are tolerant to water stress in bread wheat, 50 bread wheat genotypes were compared in a randomized complete block design with three replications under both the non-stress dry farming with two complementary irrigation and the water stress dry farming conditions in Khorramabad, Iran. An...

Extended Abstract Introduction and Objective: Due to the water resources limitation required for agriculture in Iran, providing effective methods to reduce the negative effects of drought on crop yield is one of the important studies to plant breeding. Drought tolerance in crops is very important. By using different cultivars of crops that are able to produce relatively good yield in drought s...
To estimate the relationship between honey yield and some of the morphological characters, five queen-daughters from each of 30 queen-mothers were studied. The queen-mothers were selected randomly from the apiary of Research Center of Animal Science and Natural Resources in Isfahan Province. Summer honey yield was measured from the difference of honey comb before and after honey extraction whil...
This will enable an evaluation of the Return On Investment (ROI) using the new concept of Yield Index “e-lYI” (e-learning Yield Index), introduced in this study. The Yield Index “e-lYI” suggests an original way to evaluate the implementation of e-learning methodologies into campus based environments; still, the new index will help professionals involved in the management of the transition from ...
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
