Effects of Planting Dates and Varieties on Growth and Yield of Broccoli During Rainy Season

Abstract

Broccoli (Brassica oleracea var. italica) is one of the most popular vegetable crops in many countries of the world as its nutritional importance. It has the most exacting climatic and cultural requirements, which limit its commercial production to a few favored locations. In Thailand, broccoli has been expending in recent years and amount of increasing production. It is best planted in the North where the weather is cool or in the Northeast during winter season. The South has tropical climates and raining all year round, but farmers can produce broccoli during early summer by using the heat-tolerant varieties. Although the broccoli is highly priced and still wanted by consumers in the rainy season, the farmers might not choose to grow as the problems with low productivity. Thus, the selection of suitable planting dates and varieties is crucial for successful cultivation during rainy season in the South. The experiment was performed to evaluate the effects of planting dates and broccoli varieties on their growth and yield responses during rainy season. Four broccoli

Performance of Different Varieties with Respect to Growth, Yield and Quality of Broccoli (Brassica oleracea var. italica L.) under North Gujarat Conditions

“…The variation in different varieties with respect to plant height might be due to their genetic makeup and also maximum number of days taken for head harvest in variety Palam Haritika. These findings are in accordance with the findings of Nooprom et al, (2013), El-Bassiony et al, (2014, Singh et al, (2014), Hafiz et al, (2015) and Thakur et al, (2016) in broccoli.…”

“…This similarity and dissimilarity among the varieties in number of days taken for head initiation may be attributed to the variability in their genetic configuration and variability with respect to suitability of the climate of the particular region. These results are in corroborate with findings of Dev (2012), Thapa and Rai (2012), Nooprom and Santiprachi (2013), Gogoi et al, (2016), andThakur et al, (2016) in broccoli.…”

“…The earliness in edible maturity might be due to genetical difference among the different varieties. These results are collaborating with the findings of Thapa and Rai (2012), Nooprom and Santiprachi (2013), Gogoi et al, (2016), andThakur et al, (2016) in broccoli.…”

“…These significant differences with respect to fresh weight of head, head yield per plot and head yield per hectare among different varieties may be due to their own-genetic makeup and the suitability of varieties to the weather conditions of this zone. These findings are in conformity with the results, El-Bassiony et al, (2014) in knol-khol, Bhangre et al, (2011) in broccoli, Moniruzzaman (2011) in cabbage, Thapa and Rai (2012) of broccoli, Uddain et al, (2012) in knol-khol, Thapa et al, (2013, Chandan et al, (2013) in broccoli, El-Magd (2013), Giri et al, (2013), Nooprom et al,(2013), Nguille et al, (2014), Singh et al, (2014 and Islam et al, (2015) and Thakur et al, (2016) in Broccoli.…”

Evaluation of broccoli (Brassica oleracea var. italica L.) varieties with respect to growth and yield in Chitwan, Nepal

“…The variation on days to head initiation among varieties might be due to its genetic makeup of a short vegetative phase which enhance early head initiation and maturity. Similar findings were obtained by Nooprom and Santiprachi (2013) as well as Thapa and Rai (2012) in broccoli.…”
