“…The decrease in amount of water from 100 to 60 % did not decrease yield significantly (p<0.05). Similar experiment conducted by Tolga Erdem et al (2010) on broccoli crop to evaluate the yield and quality of broccoli under different irrigation regimes, nitrogen applications and cultivation periods resulted there were statistical differences along nitrogen doses with respect to yield and yield components while there were statistically no significant differences in the yield and yield components among irrigation regimes. Therefore, about 20-40 % water could be saved by modifying the crop coefficient values (K c ) as per local crop and variety.…”

“…After lettuce, Broccoli is the most important vegetable widely known for anticancer health benefits to human health (Brennan et al, 2016). Tolga Erdem et al (2010) conducted experiments on broccoli crop to evaluate the yield and quality of broccoli under different irrigation regimes, nitrogen applications and cultivation periods resulted in obtaining the highest yield in the spring crop (11.02 t/ ha) followed with the autumn crop (4.55 t/ha). Further, an experiment to evaluate the response of broccoli to irrigation scheduling and methods under drip, sprinkler and surface irrigation was carried out by Himanshu et al (2013) and observed that that to obtain higher marketable yield and net return under semi-arid climate, the crop should be irrigated at 150-160 % of pan evaporation replenishment with drip or micro sprinkler irrigation system.…”

Abstract:Geometric increase in population coupled with rapid urbanization, industrialization and agricultural development are causing increased pressure on global water resources. Agriculture is the largest consumer of fresh water resources, thus the scope of enhancing water productivity in agriculture is taken to be the priority area of research. The right amount and frequency of irrigation is essential for optimum use of limited water resources for crop production as well as management. A field experiment with split plot design was carried out during November to February 2015-16 at PFDC (Precision Farming Development Centre), Water Technology Centre, IARI, New Delhi to study the effect of different irrigation levels and frequencies on Broccoli (Brassica oleracea var. italica) under drip irrigation. The experiment included three levels of irrigation frequencies: N 1 (once every day), N 2 (once every 2 days) and N 3 (once every 3 days) with different irrigation levels of 100, 80 and 60 % of crop evapotranspiration (ET c ). Results revealed that drip irrigation frequency significantly (p<0.05) affected the broccoli yield. The maximum yield (24.46±0.18 t/ha) was obtained with 80% of ET c with once in 2 days irrigation followed by 100% of ET c with once in 2 days. Lowest yield (16.53±0.1 t/ha) was obtained at 60% of ET c at once in 3 days irrigation. Overall, it was observed that irrigation on 80% of ET c with once in two days is an appropriate cycle for optimum yield of broccoli.

A field experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during winter season, 2007 -2008 to determine the effects of N and B on the yield and hollow stem disorder of broccoli. Four levels of N as 0, 60, 120, 180 kg ha -1 and four levels of B as 0, 0.5, 1.0 and 1.5 kg ha -1 constituting sixteen treatments were applied in a split plot design with three replications. Applied N and B had significant impact on the yield and hollow stem disorder of broccoli. The highest curd yield of 15.14 t ha -1 was obtained by 180 kg N ha -1 . The incidence of hollow stem disorder was increased by increasing rate of N application and the highest value of hollow stem index of 1.38 was found with 180 kg N ha , which might be recommended for farmer's practice in the Shallow-Red-Brown Terrace Soil of Madhupur Tract.

“…N leaching ratio was calculated as total N leaching quantity minus the N leaching quantity in the no-fertilizer treatment, divided by the N application amount in different treatments ). Water use efficiency (Erdem et al 2010) was calculated as total spinach yield divided by the evapotranspiration. Nitrogen use efficiency was calculated as total spinach yield minus the yield in the unfertilized treatment, divided by the amount of nitrogen fertilizer in different treatments.…”

L. 2015. The effects of different water and nitrogen levels on yield, water and nitrogen utilization efficiencies of spinach (Spinacia oleracea L.). Can. J. Plant Sci. 95: 671Á679. Water and nitrogen (N) are important factors that affect crop yield. The objective of this study was to explore the interactive effect of water and nitrogen on biomass production, yield and growth responses, water and nitrogen use efficiency of winter-grown spinach. A field experiment was grown with treatments of varying water (W) and nitrogen (N) levels near Shanghai, China. Leaf area, shoot biomass and height of spinach increased with the application of N in the well-watered treatment. The highest chlorophyll content was found in spinach treated with N 2 (170 kg ha(1 nitrogen). A response surface analysis was done on plant height, leaf number, leaf weight, and plant yield of each spinach plant at different water and nitrogen levels. The equation for each of the response surfaces was taken and solved for the mathematical optimum of the curves. Abundant water supply resulted in the highest spinach yield. Yield of spinach increased with N application rates but decreased when the N was excessive. Compared with the low water treatment (W 3 ), a higher N leaching ratio was observed in the high water treatment (W 1 ), regardless of N treatment. With the increase of N application, N use efficiency of spinach significantly decreased, while water use efficiency of spinach increased. In conclusion, water levels between 36.15 cm and 42 cm, and nitrogen applications between 86 and 152.74 kg ha(1 could be recommended as the optimal treatment for spinach growth.
