Lei Mamawh Dan

    La hi lei chi hrang hrangah a chin theih a, lei thil lutuk (sandy soil), lei al lutuk leh tui tlin theihna hmunah erawh chin loh tur a ni. Lei ban lam pangah a tha duh deuh bik a, lei tha hmun, tui fawm tam thei chi lei-ah a tha bik thin. La chinna hmunah reng reng tui a tling thei tur a ni lo. 

Lei Sawngbawl Dan tur

    La hian zung thuk tak a nei thin a, chuvang chuan La chinna hmun tur chu uluk taka cheh phut thin tur a ni. Lei hi 15-20 cm vel a thuk a leh phut vek tur a ni a, chu mi hnuah na lo deuh in vawi 2/3 lei chu leh nawn leh vek thin tur a ni. Lei leh na hnu lei tlang lian lutuk chu vuak phut leh vek tur a ni. Tui pek tur kan nei tha a nih chuan lei leh zawh velah, La kan chin hmain lei chu hneh takin tui pek vek tur a ni.

A Chi Sawngbawl Dan

    La chi hi a kawr a chhah em avangin chin hmain Concentrated Sulphuric Acid ah 'delint' (chiah) tur a ni a, Sulphuric Acid hi 70 cc - 100 cc vel a taka siamin La chi Kg 1 chiah tur a ni. 

    La chi ei chhe tu chi kha Pink Ball Worm naute te hian La hi a chhung rilah an ei chhe thin a, hei hi Sulphuric Acid khian a ti hlum thin bawk a ni. Natna dang leh rannung dang pawh Sulphuric Acid hian a that hneh hle a, La chi chutiang a sawngbawl tawh chu rei lo te-ah a to thuai thuai thin. Chemical hmanga La chi hi kan chiah thei lo a nih hlauh chuan bawngek, mei vap leh tui nen a chiarin kan nuai pawlh tur a ni a, chutiang a La chi nuai tawh chu dai hlimah dah ro tur a ni. La chi chu rannung leh natna in a ei chhiat loh nan Emisan 5 g, streptocycline 1g leh succinic acid 1 g te nen tui litre 10-ah darkar hnih chhung chiah tur a ni, hei hi La chi Kg 6-8 thleng a pawlh tawk viau in a rinawm.

    Chemical fertilizer kan pe dawn a nih erawh chuan 80-100 Kg Nitrogen, 30 Kg Potassium, 40 Kg Potash te kan pe tur a ni. Potassium leh Potash fertilizer te hi thlai chi kan tuh hunlaiin a vaiin vawikhatah pek nghal vek tur a ni a. Nitrogen bik erawh a chanve hi La chi kan tuh laiin pek theih ni sela, a chanve dang erawh chu a par hmasa ber a chhuah hunah pek chauh tur a ni thung. 

Tui Mamawh Dan

    La chin atanga ni 45 velah tui pek theih ni sela a tha hle a, tui pek hnem hian a kung a than tir vak a, a tha ber lem lo. Ni 45 hnuah chuan tui hi nasa lutuk lovin kar 2 dan zelah pek mai thin tur a ni. La a par tawh hnuah chuan tui nei lo leh ro lutuk a dah an tha lova, a par a til nasa in a thar a tlem phah thei a ni. La kung la naupang te hian tui tling an haw em em mai a ni, tui pek hun laiin tui tih tlin miah loh tur a ni.

Hlo thlawh Dan tur

    La kung te hi hlo hian an ti buai nasa ve thei em em mai a, ni 50-60 an tlin hma phei chuan hnim leh hlo lakah La chu ven a thlawhfai emaw damdawi a kah reng thin tur a ni. Hlo tur atan Fluchloralin emaw Alachlor te hman a tha hle.

Harvesting

    La thar chu vawi 2 emaw vawi li lai kut in a lak mai tur a ni. La kan lak chu hnah thel, hmawlh emaw a kung tang ro te nen chawh pawlh miah loin lak tur a ni a, La chu a ro tha hle tur a ni. India hmar lamah chuan La hi October thla velah a vawikhat nan a lawh theih tawh thin a, a vawi hnih lawhna erawh November thla velah tih thin tur a ni. La kan lak tawh sa chu hmun hnawng ah emaw tui awm theihna ah dah miah lo tur a ni a, hei hi La quality a ti chhe vek thei a ni. 

    La hi dik tak a enkawl chuan 1 Hectare ah 15-20 quintals vel a tam lai a thar theih a, Hydrid ah phei chuan 25-30 q/ha lai a tam a thar chhuak thei a ni.
