Among the single treatments tested under in vivo addition of well decomposed FYM 20 tons per hectare as soil amendment recorded minimum wilt incidence of 3.75, 24.76 and 48.25 % at flowering, fruit formation and ripening stages of chilli crop, respectively, with 61.31 q ha fruit yield as compared to check (42.50 q ha). Dual application of Trichoderma viride 0.16 t ha + FYM 20 t ha recorded mini...

the main objective in production of any rainfed crop, including barley farming is to increase water productivity along with stability in the production of the rainfed crop through improvement of the agronomic management including limited single irrigation (si) and sowing date (sd). in order to determine optimal si management and limited water allocation scenarios, a field experiment was conduct...

ABSTRACT The objective of this study was to evaluate the effects saline water irrigation management strategies and potassium doses on concentration photosynthetic pigments, gas exchange, fruit production ‘BRS GA1’ yellow passion fruit. experiment carried out under field conditions using a randomized block design, with treatments based 6 × 2 factorial scheme, related six for (irrigation low-sali...

introduction water shortage in iran has always been a limiting factor for crop cultivation. drought stress at different growth stages, especially flowering and grain filling stages decreases the yield of the plants. drought stress may limit yield of medicinal and aromatic plants by reducing the harvest index (hi). this can occur even in the absence of a strong reduction in total medicinal and a...

background and objectives: drought is one of the most important factor limiting plant growth around the world and the most common environmental stress which is limited produce approximately 25% of the world's land. production of secondary metabolites in medicinal plants changes by environmental condition and also water stress is effective factor in growth and synthesis natural compounds in...

In order to determine the best developmental stage of soybean at which maximum seed quality is attained under different shadings (S1, S2, S3: 0, 35 and 75% shade, respectively) and irrigation treatments (I1, I2, I3, I4: irrigation after 60, 90, 120 and 150 mm evaporation from class A pan, respectively), two split plot experiments using randomized complete block design with three replications we...

introduction safflower) carthamus tinctorius l.) is a tolerant plant to water deficit due to long roots and capability for high water absorption from soil deeper parts. safflower can growth successfully in regions with low soil fertility and temperature. behdani and mosavifar (2011) reported that drought stress affect on yield by reducing yield components and agronomic traits. biofertilizer dur...

introduction dehydration is one of the limiting factors of crop production. it results from increasing the amount of water losses from leaf or inadequate water absorption rate or combination of both. zinc used in many enzymes of the plant tissues and have catalytic role in activation of some enzymes. zinc is involved in the synthesis and degradation of proteins and is an essential micronutrien...
