“…Zafar et al (2011) found that organic + inorganic fertilizer application resulted in a greater shelling percentage than sole application of either. Ali et al (2002) also reported the greatest value for shelling percentage at 150 kg N ha −1 . Wasaya et al (2012) concluded an increase in shelling percentage resulted from greater N dose and deep tillage practice.…”

On-farm research was conducted to investigate the effects of nitrogen (N) and compost (C) on yield and yield components of spring maize (Zea mays L.) under conventional and deep tillage system (T) at the research farm of the University of Agriculture, Peshawar, Pakistan, during spring 2013. The experiment was laid out in a randomized complete block design with split-plot arrangement, using three replications. Three compost levels (0, 1, and 2 t ha −1 ) and two tillage systems (conventional and deep tillage) were allotted to the main plot, whereas N levels (60, 90, 120, and 150 kg N ha −1 ) were allotted to subplots in the form of urea. Nitrogen and compost levels had significantly affected all the parameters. Plots treated with 150 kg N ha −1 increased ear length (31 cm), grains ear −1 (413), thousand-grain weight (240.2 g), grain yield (3097 kg ha −1 ), straw yield (9294 kg ha −1 ), harvest index (24.7 percent), and shelling percentage (81.7 percent). Compost applied at 2 t ha −1 increased ear length (32 cm), grains ear −1 (430), thousandgrain weight (242.3 g), grain yield (2974 kg ha −1 ), straw yield (8984 kg ha −1 ), harvest index (24.6 percent), and shelling percentage (83.2 percent). Tillage system had significant effect on all parameters except ear length and harvest index. Deep tillage system produced more grains ear −1 (365), thousand-grain weight (233.3 g), grain yield (2630 kg ha −1 ), straw yield (8549 kg ha −1 ), and shelling percentage (79.6 percent). It was concluded from the results that application of 120 kg N ha −1 + 2 C t ha −1 under a deep tillage system could improve spring maize yield and yield-contributing traits under semi-arid conditions.

“…Maximum number (46) of days to tasseling was recorded in case of (Jalal). Minimum number (6) was also recorded in (Jalal) which was (43). Highest number (46) of days to tasseling was recorded from treatment which applied with (150, 150) N:P kg•ha −1 .…”

“…It is needed for growth, nucleus formation, photosynthesis, utilization of sugar and starch, cell division and fat and albumen formation. Phosphorus is readily translocated within the plants and it moves from older tissues to younger tissues Ali et al [6] [7]. Phosphorus in adequate amount is necessary for earlier maturity, rapid growth and improves the quality of vegetative growth.…”

“…Hence, the improved N uptake in grain yield of maize may lead to improved grain yield. A combine application of nitrogen and phosphorus increase the N uptake of maize reported [41]. Total uptake (above-ground dry biomass) =grain + straw uptake D. Effect of NPSB fertilizer application on phosphorus nutrient uptake of maize Application of 250 NPSB + 100 Urea + 100 KCl gave the maximum grain P uptake (64.45kg/ha) and above-ground dry biomass (88.75 kg/ha) yield, while the minimum P uptake (8.02 kg/ha) and above-ground dry biomass P uptake (12.59 kg/ha) was recorded from the control treatment.…”

Farmer in different parts of Ethiopia uses a similar type of fertilizer and amounts that are below the crop requirements, even the low soil fertility which limits crop production in general. To solve the over-blanket fertilizer application over different agroecology Ethiopian Soil Information System (EthioSIS) mapped the soil fertility and recommended types of fertilizer for a specific location. A NPSB type of fertilizer where recommended for Beko village, but the rate of this fertilizer type was not studied so far. So, this field experiment was conducted to determine the rate of NPSB fertilizer type and nutrient use efficiency of maize during the 2018 cropping season. A total of eight treatments with four replications were laid out in a factorial randomized complete block design. Treatments were control (zero fertilizer), previously blanket recommended nitrogen and phosphorus (92 N+ 69 P2O5) kg/ha, 150 NPSB +100 urea +100 K2O kg/ha, 200 NPSB +100 urea + 100 K2O kg/ha, 250 NPSB +100 urea +100 K2O kg/ha, 150 NPSB +150 urea +100 K2O kg/ha, 200 NPSB +150 urea +100 K2O kg/ha and 250 NPSB +150 urea +100 K2O kg/ha. Data were statistically analyzed by statistical analysis system (SAS) and mean treatment differences were compared by least significant differences (LSD). An analysis of variance indicated that application of NPSB fertilizer was not influenced plant height, ear height, ear length, cob length, number of ears per plant, thousand seed weight, harvest index, and shelling percentage as compared to the previously blanket recommended Nitrogen and Phosphorus (NP) fertilizer but grain and above-ground dry biomass were influenced except the application of 150 NPSB +100 urea. Application of 250 NPSB + 100 urea gave the highest maize grain yield (8828.2 kg/ha). Application of NPSB fertilizer improved the nitrogen and phosphorus use efficiency of maize compared to the previously blanket recommended NP. The highest N use efficiency (64.75 kg/ha) was obtained from the application of 200 NPSB +100 urea, while the lowest N use efficiency (23.89 kg/ha) was from the previously blanket recommended NP fertilizer. As economic analysis indicated that the application of 150 NPSB +100 urea is recommended for the study area.
