The experiment was conducted at the research field of Agronomy Division, BARI, Joydebpur, Gazipur during consecutive seasons of 2011-12 and 2012-13 to optimize fertilizer rate for potato hybrid maize relay cropping system. Seven treatments viz., T 1 = Farmers" fertilizer dose of potato (FFDP: N 504 P 162 K 309 kg/ha) + Farmers" fertilizer dose of hybrid maize (FFDM: N 0 P 0 K 0 kg/ha), T 2 = FFDP + 100% N of recommended fertilizer dose of hybrid maize (RFDM: N 255 P 55 K 140 S 40 Zn 6 B 2 kg/ha), T 3 = FFDP + 100% N & 25% others of RFDM, T 4 = FFDP + 100% N & 50% others of RFDM, T 5 = Recommended fertilizer dose of potato (RFDP: N 198 P 44 K 194 S 24 Zn 6 B 1.2 kg/ha) +100% N of RFDM, T 6 = RFDP +100% N & 25% others of RFDM, and T 7 = RFDP +100% N & 50% others of RFDM were tested on potato-hybrid maize relay cropping system. Potato (var. Diamant) and hybrid maize (var. BARI Hybrid Maize-9) were used in this experiment. Results indicated that yield of potato (28.38 -28.83 t/ha) did not differ significantly but yield of hybrid maize (4.90 -8.74 t/ha) varied significantly under different treatments. The higher grain yield (8.74 t/ha) of hybrid maize was recorded in farmers" fertilizer dose of potato or recommended fertilizer dose of potato (8.61 t/ha) along with 100% N plus 25% other fertilizers or 100% N plus 50% other fertilizers from recommended dose of hybrid maize. The highest potato equivalent yield (41.94 t/ha) and gross return (Tk. 335520/ha) were obtained from FFDP along with 100% N plus 25% others of RFDM (T 3 ). But the highest gross margin (Tk. 219790/ha) and benefit cost ratio (3.01) were found from RFDP along with 100% N plus 25% others of RFDM (T 6 ). The results revealed that recommended fertilizer rate of potato (N 198 P 44 K 194 S 24 Zn 6 B 1.2 kg/ha) along with 100% N plus 25% other fertilizers from recommended fertilizer rate of hybrid maize (N 255 P 55 K 140 S 40 Zn 6 B 2 kg/ha) might be optimum for potato hybrid maize relay cropping system for obtaining higher economic return.

“…The observed differences in maize grain yield were highly associated to available mineral N following a typical LPR curve, agreeing with previous experiments under similar irrigated Mediterranean conditions (Berenguer et al, 2009;Isla et al, 2015). Low levels of available mineral N decreased leaf area, leaf N concentration, and instantaneous measurements of An at V8 and on the ear leaf at V14.…”

“…An excess of N in agroecosystems produces environmental problems associated to nitrate leaching and nitrous oxide emissions (Alvaro-Fuentes et al, 2016), a powerful greenhouse effect gas. Under the conditions of high water and N demand for maize grown in a Mediterranean climate, it is well documented that N deficiency can lead to significant yield reductions (Di Paolo & Rinaldi, 2008;Berenguer et al, 2009). The relationship between N supply and maize productivity has been well documented in the environments, but not at the leaf photosynthetic level.…”

There are limited studies about the effect of nitrogen (N) deficiency on leaf growth, N status, and photosynthetic capacity of maize grown under field conditions in a Mediterranean climate. The objective of this work was to evaluate the effect of different levels of mineral N availability on leaf gas exchange parameters of sprinkler irrigated maize. The experiment was conducted in a conventional maize field located in the central part of the Ebro valley (Spain) during two seasons. Using a portable LICOR-6400 equipment, instantaneous measurements and light response curves to gas exchange were conducted in plots with different levels of N supply ranging from deficient (no fertilized) to over-fertilized (300 kg N/ha). In addition to gas exchange measurements, mineral soil N content, chlorophyll meter readings (CMR), leaf N content, and grain yield were measured in the different plots. Results showed that grain yield reached a plateau (14.5 Mg/ha) when the mineral N available was about 179 kg/ha. CMR were linearly and highly related to total N in ear leaves. The relationship between light-saturated leaf photosynthesis measurements and CMR was significant but very weak (R2=0.13) at V8 and V14 stages but increased later in the growing season (R2=0.52). Plants with intermediate levels of N supply (48<CMR<54) tended to have slightly higher assimilation rates than plants with higher CMR readings. As the available N increased, the saturation point, the light compensation point and significant increases of dark respiration rate were observed. Under the conditions of the study, leaf N contents of 1.9% in the ear leaf were enough to maximize leaf assimilation rates with no need to over-fertilize the maize crop.

“…In ICL, the application of certain quantities of nitrogen to pastures has residual effects for the subsequent culture, even allowing for the discontinuation of nitrogen application to the corn crop (Assmann et al, 2003;Novakowiski et al, 2011). In contrast, nitrogen fertilization is an important economic and environmental issue because the profitability of the production system is greatly influenced by the high cost of nitrogen use and because excessive application increases nitrate concentrations in the soil and causes groundwater pollution (Berenguer, Santiveri, Boixadera, & Lloveras, 2009).…”

ABSTRACT. The objective of this study was to evaluate the agronomic characteristics of corn seed inoculated with Azospirillum brasilense, grown on black oat and ryegrass straw, and managed under different grazing strategies and doses of nitrogen. The experiment was conducted in Santa Maria, Rio Grande do Sul State, Brazil, during two agricultural seasons (2012/2013 and 2013/2014) in a randomized, complete block design with three replications. In the winter period, black oat and ryegrass straw were managed at different grazing heights by sheep (0.30, 0.20, 0.10 m, conventional grazing, and no grazing) with three doses of nitrogen (0, 50, and 100 kg ha The height of corn plants was greater when they were grown on black oat and ryegrass straw, and the absence of grazing favored productivity. Under drought conditions, the application of nitrogen to the pasture favored corn development, increasing plant height, ear height, and stem diameter. Inoculation with A. brasilense had a positive effect on the characteristics of yield and productivity of corn, independent of growing season and hybrid used.
