CAULIFLOWER Hybrid GS-75 (IMP) (ADVANTA)​

Cultural Practices Cauliflower
Season	i) Tropical ii) Sub Tropical iii) Temperate
Climate	During transformation phase from veg. to curding & curd dev. climate / temperature plays vital role though some deviations are attributed to light & water condition. It is physiologically different crop in Cole group due to intermediate phase of curding 0 0 0 between vegetative & generative. Curding from 5 C to 28 -30 C, however, for transformation certain amount of vegetative growth will be necessary to pass over 0 0 0 juvenile phase: optimum is 23 C. Tropical crop - curding at 15 -20 C. When tropical varieties grown in low temperature not only they button quickly after passing juvenile phase but leads to riceyness to green bud formation. For vegetative growth: few degrees higher than optimum needed for curd dev. (10-15 days), temperature should not fluctuate too much - deteriorates.
Nursery	Nursery Management - Tips to be followed & monitored : i) Sow the seeds in Pro trays of 98 cavities by using the sterilised cocopeat as a media, th  ii) At 5 day after sowing mild spray with Uthane M-45 @ 1g/litre of H O + Ulala 2 0.3 g/litre of H O or Saaf @ 1g/litre of H O + Ulala 0.2 g/litre of H O. 2 2 2 th iii) At 15 day after sowing spray with Saaf @ 1g/litre of H O + Ulala 0.2 g/litre of 2 H O. 2 st iv) At 21 day after sowing spray with Uthane M-45 @ 1g/litre of H O + Ulala 0.3 2 g/litre of H O or Saaf @ 1g/litre of H O + Ulala 0.2 g/litre of H O. 2 2 2  v) Hardening of seedlings is must before transplanting. Seedling will be ready for transplanting in 22-24 days after sowing. Transplanting has to be done preferable in evening hours to avoid sun shock & mortality
Soil & Land Preparation	For early crop in tropics & sub-tropics, light to light medium soil preferred so that the drainage is easier in rainy season. Results are disappointing that the growth is checked due to water stagnation. Therefore in cauliflower even steady growth is imp. Since rampant growth may retard the curd formation & may show growth of bracts.
Seed Rate	100-120 g/acre
Irrigation	Irrigate as & when required based on the soil type & the local practices.
Spacing	Row to Row : 45 cm & Plant to Plant : 30-40 cm
Fertilizer Kg/Acre	NPK- 80:50:60
1st Picking	Depend upon the Segment : Early tropical 45-50 Days / Tropical or Sub tropical 55-60 days / Temperate - 75 to 90 days
Growth Regulator	GA3 effect : more pronounced when curd initiation delayed by high temperature (regulates harvesting time)
Yield T/ha	16-18 T
Avg. per Fruit Weight (g)	16-18 T
No. of Fruits Per Plant	Average 40 – 60
Major Impediment	High temperature-Riceyness (Premature initiation of floral buds is characterized as, velvety appearance owing to dev. of small white flower buds at the curding stage, pedicel show longitudinal growth : due to fluctuation in temperature high/low during curding; rampant growth, high RH, heavy nitrogenous dressing; at high temperature bracteates growth.
Remedies / Control Mmeasures	Uniron 1.0 ml/l for control of DBM, Ulala 0.5 ml/l for Leaf minor control.
Harvesting	Cut the curd immediately it reaches prime condition, if late -flower stalk elongates & loose, riceyness / fuzzy curd- poor quality Trim large leaves keeping sufficient jacket leaves to protect the curd.
Key Points	Pods-Siliqua Bo - Deficiency - Water soaked patches in the centre of curd; later stem becomes hollow with water soaked tissue surrounding the walls of cavity. Adv. Stage rusty brown / pinkish - areas dev. On curd surface. CM - 15 kg Borax/ha Molybdenum - Plants chloratic, turn white along the leaf margin, cupped & wither, eventually leaf dries, growing point collapses. Older plant-lamina of newly formed leaves are irregular in shape, frequently consisting of only a large bare midribwhiptail. N deficiency develops Mo deficiency & buttoning
Care	i) For avoiding Riceyness - hardened seedlings likely to give better results & since early crops are raised in monsoon, 5-6 week old seedling stand better chance of establishment; ii) Buttoning - Check in vegetative growth of seedlings, followed by suitable temperature for transformation to curding may induce this malady. Other reason - delayed transplanting) cured by P O application
