with population growing throughout the world, it is necessary to optimize water use,especially in agricultural lands. in order to conduct technical and economical evaluation ofdrip and furrow irrigation methods under deficit irrigation of cotton, a field experiment wascarried out during 2010 growing season at experimental farm of orzoueyeh agricultural andnatural resources research center in ke...

abstract a field experiment was conducted at iranian plant protection research farm in karaj during 2009 to evaluate the effects of diffrent planting patterns, times of mechanical control and herbicides application on weeds density and biomass in sugar beet farms. the experimental design was split–split plot based on randomized complete block design (rcbd) with four replications. planting patte...

Nitrogen (N) plays a vital role in the productivity of maize (Zea mays L). To investigate fertilizer effects N on yield and growth hybrid variety (Gorilla), experiment was carried out at research farm University Swabi, Pakistan, during summer 2017-18. Four levels (Urea, Urea + Farm Yard Manure (FYM), Compost, Poultry (PM)) were set present study. Randomized complete block design (RCBD) used wit...

The increasing population in Nigeria has resulted a high demand for food. Some of cucumber production constraints include limited yielding varieties and appropriate spacing. Therefore, two field trials were conducted to determine growth yield 2019, at the research farm Federal University Agriculture Abeokuta (Latitude 7°15¹N Longitude 3°25¹E). experimental design was three-time replicated Rando...

Now days, turf management has encountered with water deficit, mostly due to low precipitation also industrial, agricultural and household demand and consumption. So, the objective of this project was to identify drought tolerance of warm and cool season turfgrass cultivars to different levels of regulated-deficit irrigation. The field experiment was set out in a split-plot based on completely r...

Cotton is the backbone of Pakistan’s economy. More than half export Pakistan depends on cotton and cotton-based products. Morphological quantitative traits are important for estimation yield. In this regard, a study was conducted to evaluate morphological responses crop at experimental farm MNS-University Agricultural Multan during year 2019-2020. Four varieties with different time windows (ear...

factorial and split-plot designs are two statistical procedures used to conduct agricultural field experiments. both designs are used frequently to quantify the main and interaction effects of two or more factors. however, split-plot design is recommended for specific situations depending on major and minor goals of the study, characteristics of the factors, and precision of statistical testing...

The present study was carried out at the experimental farm of Tag El-Ezz Agricultural Research Station (30o 59\ N latitude, 31o 58\ E longitude´), Center, Dakahlia Governorate, Egypt, to effect foliar spraying arginine on four soybean cultivars under salinity stress. This experiment laid in a split plot design with three replicates during two successive summer seasons 2020 and 2021.
