The Saffron Yield Estimation Model (SYEM) was modified for salinity conditions, cowmanure application and planting methods using two-year experiments data in Badjgah region ofIran. A split-split plot arrangement was conducted in complete randomized block design duringtwo years with irrigation water salinity levels (0.45 (fresh water, S1), 1.0 (S2), 2.0 (S3) and 3.0(S4) dS m-1) as the main plot,...

Damage to cotton by Rotylenchulus reniformis below plow depth was evaluated in a sandy clay loam soil at Weslaco, Texas. In December 1999, 14 holes on 51-cm centers were dug 91 cm deep along the planting bed and adjacent furrow and 2 ml of 1,3-dichloropropene was placed 91, 61, and 30 cm deep as each hole was refilled and packed. This technique eliminated 96%, 81%, and 74% of R. reniformis down...

Furrow formation is one of the most labor-intensive operations in potato cultivation technology. The article discusses justification and determination furrower parameters planter. Analytical dependences height junction point disks width furrow bottom are obtained, taking into account technological parameters, its design features physical mechanical properties soil. Potatoes planted usual way. m...

stand establishment in crusting soil is one of the main concerns in the production of crops with delicate seedlings such as cotton, onions and rape seed. crust breaking, maintaining soil moisture and adding chemical and organic amendments to soil are different methods to weaken soil strength and allow the shoots to emerge. these methods are not always successful because they depend on factors s...

in order to evaluate the effects of drought stress and planting method on yield and yield components of two chickpea cultivars (cicer arietinum l.), an experiment was carried out at the research field of faculty of agriculture; shiraz university, using a split factorial randomized complete block design with four replications. the main factor was irrigation stop at different growth stages of chi...

Twin-row planting in maize (Zea mays L.) has potential for reducing plant-crowding stress optimizing grain yield and resource use. A study was conducted 2020 2021 on a Dundee silt loam the Lower Mississippi Delta (LMD) region of United States to evaluate irrigation water use efficiency (IWUE) single-row (SR) twin-row (TR) patterns with same seed rate under four regimes: rainfed (RF), all-furrow...

Abstract The objective of this work was to evaluate sugarcane (Saccharum spp.) yield in response corrective and maintenance phosphorus fertilization Oxisols. Two experiments were carried out randomized complete blocks with four replicates. In the treatments, 150 kg ha-1 P2O5 broadcast incorporated before planting. 40 per year applied over trash blanket. All except control, fertilized 170 planti...
