“…This means that S.C 2031 variety is more able to extract water from soil zones, and convert it into plant biomass than other varieties. [41] reported that maize plants are especially sensitive to water stress because their root system is relatively sparse.WUE of maize cultivars has been studied by several workers including [42] and [43]. These studies are important for identifying maize cultivars that are efficient in the use of limited soil water for biomass and grain yield production.…”

“…In Khyber Pakhtunkhwa the total production was 959.9 thousand tons with an average yield of 1880 kg ha -1 [3]. Production of crop and soil fertility dramatically enhanced by nitrogen application [4] increased bio mass (25-42%) in maize was conveyed as a result of nitrogen application [5]. The nitrogen applications has positively improved the penology of crop, also increase the rate of germinations and increased the number of plants [6].…”

The performance of organic and inorganic fertilizers have shown positive effects on plant growth in crop production, a study was conducted to measure the effect of various levels of organic and inorganic fertilizers in maize. The experiment was conducted in randomized complete block design with split plot arrangement having three replications at New Development Farm, Khyber Pakhtunkhwa Agricultural University Peshawar during kharif 2009-10. Various organic fertilizers namely, (1) Higo plus (500 kg ha -1 ), farm yard manure (10 tons per hectare) both were incorporated in the soil before sowing (2) Mexicrop (500 liters in 100 liters of water) was sprayed after emergence. NP fertilizers was applied as an inorganic fertilizers source under following rates; 120:80, 150:100 and 180:120 kg ha-1 at sowing, whole P was applied at once, but nitrogen was applied in split doses. Organic and inorganic fertilizers and control were kept in main plot. While maize varieties (i.e. Jalal, Pahari and Azam) were sown in sub plots. Delayed tasseling (62.2), silking (71.1) maturity (98.6), taller plants (175 cm), plants population at harvest (61481 ha -1 ) and biological yield (11111 kg ha -1 ) were recorded when NP was applied at the rate of 180:120 kg ha -1 , whereas highest harvest index (37.1%) and maximum plants population at harvest (65556) were recorded when NP at 150:100 kg ha -1 was used. Jalal variety emerged as best variety with delayed tasseling (61.20), silking (68.6) and produce taller plants (171 cm) with maximum biological yield (10234 kg ha -1 ). In conclusion inorganic source of fertilizers (NP) proved better than organic and Jalal variety is strongly recommended because of better performance in the agro-climatic condition of Peshawar.

“…The topsoil is (20-40 cm) in the experiment station has a field capacity of 23-25% and heavy loam. The soil is air-dried by natural, grinded finely and over 5 Randomized block design with three replications and the treatments consisted of three levels of irrigation and three levels of N fertilizer were used. Three irrigation levels were W1 (water deficit at seedling stage), W2 (water deficit at jointing stage), W3 (water deficit at filling stage) and nitrogen (N) fertilizer levels were F1 (0.1 g pure N kg -1 soil), F2 (0.2 g pure N kg -1 soil) and F3 (0.3 g pure N kg -1 soil).…”

“…The research found that water use efficiency of maize is increased by application of fertilizer [4]. The other reported that research the grain yield response and N-fertilizer recovery of maize under deficit irrigation and find that the range of grain yield reduction under deficit irrigation treatments, DI 50 and PRD 50, is 10-25% and significant (P ≤ 0.01), compare to FULL irrigation practice [5]. N-uptake ability is reduced to about 20% of the well-watered control only when the soil water content is decreased to 5%.…”

Abstract. Soil water and nutrients are key factors for plant growth and development as they are involved in many processes in plants. The purpose of this study was to investigate the effect of water deficit in different growth stages on maize growth and water use efficiency. Randomized block design with three replications and the treatments consisted of three levels of irrigation and three levels of N fertilizer were used. Three irrigation levels were W1 (water deficit at seedling stage), W2 (water deficit at jointing stage), W3 (water deficit at filling stage) and nitrogen (N) fertilizer levels were F1 (0.1 g pure N kg -1 soil), F2 (0.2 g pure N kg -1 soil) and F3 (0.3 g pure N kg -1 soil). The control treatment was composed of full irrigation and without N fertilizer application (CK). The results indicated that the interactions between irrigation and N fertilizer were important for shoot dry matter and root dry matter. The ranking of N fertilizer treatments, from high to low accumulations of root and stem-leaf dry matter averages, was F1>F3>F2. The falling of accumulation of nitrate in plants was mainly attributed to the proper enhancing ammonium reduced the adsorptive capacity of nitrate. Water deficit at different growth stages were significantly increase the total N content of stem-leaf. In conclusion, the maize can repair itself so they stop growing when water deficit at seedling stage, but do not die. They simply resume growth later when the water supply is plenty.
