Effects of Nitrogen Fertilizer on Yield Quality and Nutrient Content in Broccoli

Effect of Urea Super Granule and Prilled Urea on Yield and Yield Attributes of Broccoli (<i>Brassica oleracea</i> var. <i>italica</i> L.)

“…Mukherjee (1986) reported that the USG with deep placement provided a zone of concentrated urea solution where the denitrifying bacteria cannot enter and therefore N is left at the root zone for uptake by the plants. This result was in agreement with the findings of Mohanthy et al (1999) and Yoldas et al (2008). Greenwood et al (1980) optimize the N dose to receive the maximum broccoli yield with the recommended doses from 175-252 kg N ha -1 .…”

“…This higher lateral head production may be due to the effect of prolonged supply of N by the deep placed USG as the residual effect. Yoldas et al (2008) who found that N rates significantly increased yield, average weight of main and lateral heads, and the diameter in broccoli compared to control. Similar results were reported by Chao-Jiong (2010) who showed that both the average weight and diameter of main head and lateral heads of broccoli were significantly increased with the increase of nitrogen fertilization from 200-300 kg N ha -1…”

“…Slow nutrient releasing fertilizers can play positive role in lateral head yield of broccoli. It was reported that nitrogen rates significantly increased yield, average weight of main and lateral heads, and the diameter in broccoli compared to control (Yoldas et al, 2008;ChaoJiong, 2010;Ouda and Mahadeen, 2008;Moniruzzaman et al, 2007 andHussain, 2004). Hussain (2004) also reported that number of lateral head plant -1 was decreased with the increasing level of N from 60 kg ha -1 and the highest number (4.053 plant -1 ) was recorded from 60 kg N ha -1 where the highest level of N (180 kg ha -1 ) produced only 3.52 lateral heads plant -1 which supported the present findings.…”

Effect of Bio-Organics and Mineral Nutrients on Yield, Quality and Economics of Sprouting Broccoli (Brassica oleracea var. italica)

“…It is a high value exotic vegetable and cultivated for its tender flowering head and the secondary heads i. e. spears which develop in the axils of leaves and may contribute up to 50 per cent of the total yield. Generally it can be classified into three distinct group viz., white purple and green, out of which green type is highly nutritious (Yoldas et al, 2008). Broccoli is rich source of vitamins, minerals and essential amino acids, also contains the compound namely, glucoraphanin, which can be processed into an anti-cancer compound sulphoraphane (Shiwani et al, 2016).…”

Effect of Inorganic and Organic Fertilizers on Yield and Economics of Broccoli (Brassica olerasia var. italica)

“…It was a rare cole crop in India but now it is gaining popularity in metropolitan cities, reputed hotels and restaurants (Maurya, 2008). Generally it can be classified into three distinct group viz., white purple and green, out of which green type is highly nutritious (Yoldas et al, 2008). Broccoli is rich source of vitamins, minerals and essential amino acids, also contains the compound glucoraphanin which have anticancerous properties (Swarup, 2012).…”
