HI
1531 wheat variety is the first early maturing
semi-dwarf bread wheat variety ever evolved in the
history of drought tolerance breeding in Central
India. It has been recommended for rainfed and
restricted irrigation conditions of Central Zone.
Developed by IARI Regional Station, Indore, this
variety gives an average yield of 25 quintals/hectare
under rainfed condition while under restricted
irrigation it is 27 q/h. Having superior yield
potential and resistantce to leaf rust over available
commercial varieties, HI 1531 would improve the wheat
productivity and profitability under limited input
conditions, in Central Zone, by ensuring early arrival
of best quality chapatti wheat in the market.
DBW 16 wheat variety, developed by Directorate of
Wheat Research (DWR), Karnal, is resistant to yellow
and brown rusts and amenable to late and very late
sowings. It is better in resistance to leaf blight as
compared to all the existing varieties and has been
identified for North Western Plains Zone (NWPZ), which
contributes to about 40% of the total wheat production
of the country. It matures in 120 days with an average
yield of 39 q/ha.
HD
2888 wheat variety, developed by IARI, New Delhi, is
tolerant to drought/moisture stress as it has yielded
highest over all checks and qualifying varieties under
rainfed conditions. The variety has been identified
for North Eastern Plain Zone. It carries a high degree
of resistance to stem rust and moderate degree of
resistance to leaf blight, which occurs in this
region. The average yield is 23 q/ha and has high
extraction rate (flour recovery) without disturbing
the quality of wheat and micronutrient content.
For Peninsular Zone- Maharashtra, Karnataka, Andhra
Pradesh, Goa and plains of Tamil Nadu- NIAW 917 and
PBW 533 varieties have been identified. While NAIW 917
is superior in yield (average yield 43 q/ha), disease
resistance and quality, PBW 533 is resistant to both
stem and leaf rust with average yield of 37 q/ha. PBW
533, developed by Punjab Agricultural University,
Ludhiana, has excellent chapatti quality and very good
bread and biscuit quality.
AKDW 2997-16 wheat variety has also been recommended
for Peninsular Zone under rainfed condition. Developed
by Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola,
this variety is expected to solve the problem of
limited choice among farmers to have high yielding,
good quality variety which will lead to enhanced
productivity. DDK 1025 Dicoccum variety also has been
recommended for this region since the average yield is
of 38 q/ha along with disease resistance to stem and
leaf rust.
In
Barley RD 2660 variety has been identified for North
Western Plain Zone. It is superior in yield and
disease resistance as compared to the check varieties.
The average yield is 27 q/ha.
The major recommendations made by the Resource
Management group at the meeting are as follows:
-
Zero tillage is now becoming prevalent in north
western and north eastern plains zone. For
achieving high yields in zero tillage, 1/3rd
nitrogen (50 kg/ha) and full dose of phosphorus (60
kg/ha) and potash (40 kg/ha) should be applied at
the time of wheat sowing. The remaining 2/3
nitrogen (100 kg/ha) should be top dresed at first
node stage i.1, around 45 days after sowing.
-
For control of weeds in wheat under zero tillage in
north western and north eastern parts of the
country, sulfosulfuron @ 25 g/ha or tank mix of
isoproturon and 2,4-D (750+500 g/ha) should be
sprayed after first irrigation (30-35 days after
sowing). Alternatively, metibuzin @ 210 g/ha was
also found equally effective in north eastern areas,
when sprayed after first irrigation.
For optimum yield of wheat in central
zone, which comprises of Madhya Pradesh, Chhattisgarh,
Gujarat, Kota and Udaipur divisions of Rajasthan and
Jhansi division of Uttar Pradesh, basal application of
50 kg sulphur/ha through gypsum (aprox 2.5 q/ha)
should be applied.
