Ten elite wheat inbred lines / cultivars were tested for grain yield stability at five different locations under the rainfed conditions in the North West Frontier Province of Pakistan. These inbred lines were exposed to different soil types, soil fertility, moisture levels and temperatures. GxE interaction mean squares were highly significant for grain yield. The overall mean grain yield perfor...
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...
tion and nodulation, thus reducing N2 fixation capacity (Shibles, 1998). Application of N before planting or durNitrogen application during soybean [Glycine max (L.) Merrill] ing the early growth stages can suppress the N2 fixation reproductive stages has the potential to increase soybean productivity. The objective of this study was to determine the impact of N fertilizer process. Fertilizer N...
This study was designed and implemented to investigate the yield and agronomic characteristics in three differently maturing corn (Zea mays L.) hybrids (SC704, SC500, and SC260) using four nitrogen (N) levels (0, 80, 160, and 240 kg N ha-1, from Urea, N= 45%). The experiments were conducted in Zabol (South-West of Iran) and Isfahan (Central Iran) in 2014 and 2015, respectively, using a split-pl...
To investigate the effect of drought stress and plant density on yield and yield components of maize KSc 301 hybrid, a two-year study (2007-2008) was carried out in Varamin Agricultural Research Center by using strip split plot randomized based on complete block design in three replications. Four water stress levels (before flowering, during flowering and grain filling stage and no stress) were...
The effect of twelve different rates of nitrogen and phosphorus fertilizers on growth and yield of maize (Zea mays L.) in southern Nigeria was evaluated between June and October, 2007. The results of the study showed that application of 120kgN/ha + 0kgP/ha and 60kgN/ha + 40kgP/ha significantly increased the growth of maize than other treatments. The application rate of 120kgN/ha +40kgP/ha signi...
Effects of different levels of nitrogen fertilizer and cutting time of forage on grain and forage yield of barley (Hordeum vulgare L.) Karoon cultivar was studied during 1995-1996 at Ramin Agricultural Research and Educational Center, University of Shahid Chamran, Ahwas, by using a split plot design in randomized complete block with 4 replications. Main plots were assigned to five levels of N...
the objective of this study was to evaluate the effect of plant population and nitrogen rate on yield and yield components of corn (zea mays l, hybrid 704) in 2008 at mamasani region, fars province. the experiment was conducted as a factorial based on randomized complete block design with three replications. experimental factors was four plant population (75000, 90000,105000, and 130000 plant h...
Effects of different levels of nitrogen fertilizer and cutting time of forage on grain and forage yield of barley (Hordeum vulgare L.) Karoon cultivar was studied during 1995-1996 at Ramin Agricultural Research and Educational Center, University of Shahid Chamran, Ahwas, by using a split plot design in randomized complete block with 4 replications. Main plots were assigned to five levels of N f...
There are large agricultural areas in the world where wheat yields are limited by low phosphorus (P) availability. Breeding for P uptake and P utilization efficiency may reduce this problem. This study was conducted to determine the contribution of P uptake and utilization efficiency to grain yield of selected spring wheat genotypes in different environments. Thirty-eight semidwarf spring bread...
