“…Fertilizer 21N-0P-0K was applied three times at 2, 3 and 4 weeks after transplantation, while fertilizer 15N-6.5P-12.5K was used 5 and 6 weeks after transplantation. At 2 and 4 weeks after transplantation, the plots were weeded using a hand hoe (7).…”

“…The most suitable temperature for broccoli cultivation is between 10 and 20°C (1). Therefore, in Thailand, broccoliis generally cultivated in northern areas where temperatures are lower or northeastern regions during the cool season (3,7). Southern areas are humid with no cool season and unsuitable for broccoli growth, while local consumers generate high product demand (8).To meet consumption demands in the south, heat-tolerant broccoli cultivars such as 'Green Queen', 'Yok Kheo' and 'Top Green' have been developed as better adapted to humid tropical weather (9).…”

Broccoli (Brassica oleracea var. italica Plenck) growth and yield are impacted in warmer climates, especially during the dry season. Broccoli gives low yield and quality although it is heat-tolerant cultivars. Zeolite is an organic material recognized as suitable for dry season plant growth because it can adsorb cations, nutrients and water and release on demand from the plant. Application of zeolite in the soil may improve broccoli growth and yield during the dry season. The trial preparation followed a randomized complete block design (RCBD) with four replications involving five amounts of zeolite at 0, 1.56, 3.12, 4.68 and 6.24 t ha-1 using broccoli cultivar ‘Top Green’. Results showed that zeolite applications of 4.68 and 6.24 t ha-1 improved growth and yield parameters including plant width, stem diameter, time to 50% flowering and harvest, head diameter and head weight better than the other treatments. Application of zeolite at 6.24 t ha-1 gave high total broccoli yield of 8.45 t ha-1 but not significantly different (p?0.05) from 4.68 t ha-1 that gave 7.89 t ha-1. Results indicated that application of zeolite at 4.68 t ha-1 was optimal for reducing drought stress and enhancing effective growth and yield of broccoli.

The aim of this study was to determine the effect of irrigation stress on yield and yield attribute at various growth stages of broccoli under natural ventilated net-cum-polyhouse system. The research experiment was carried out at Junagadh Agricultural University, Junagadh, Gujarat, India, for two years, 2020-21 and 2021-22. The irrigation stress was imposed on 0%, 20%, 40% and 60% of the ETc at the initial, middle and end stages of the crop, respectively. The ETo was calculated by the standard and well-accepted FAO-56 method. The yield attributeparameters, such as stem diameter, plant height, number of leaves per plant and plant canopy were measured at the respective growth stages. However, the days taken to harvest, curd diameter, curd weight and yield were measured at the time of harvesting. The effects of irrigation stress level on crop growth stage were significant for stem diameter, plant height, number of leaves per plant, plant canopy, curd diameter, curd weight and yield. The interaction effect of stress imposed on crop growth stage and irrigation stress level on stem diameter, plant height, plant canopy, curd weight and yield was significant. However, the number of leaves per plant, days taken to harvest and curd diameter were not significantly different. Under irrigation stress, the application of 20% ETC at the initial and end stages promoted a greater yield in broccoli cultivation. Moreover, the yield was on par with that under irrigation stress which reached 60% at the initial stage and 40% at the end stage of the crop. It is advisable to impose irrigation stress at the initial stage and end stage of the broccoli crop when water resources are scarce under natural ventilated net-cum-polyhouse. However, irrigation stress imposed at the middle stage significantly affects broccoli yield.
