On going
Research Projects: The Centre has formulated and
working on 5 Projects in the disciplines of Horticulture,
Pathology, Soil Science and Soil/Water conservation and
Engineering.
Surveys:
As per the directives from ICAR, surveys of pomegranate orchards in the Maharashtra state
were carried out during July 3 to 5 2006 and February 19 to 22 2007 by the scientist of NRCP Solapur,
MPKV Rahori, IIHR Bangalore, Directorate of plant protection Nagpur and Bangalore to assess the damage
to pomegranate crop due to importanat diseases and insect-pests prevalent in the region.
Research
Achievements:
Crop improvement
Crop production
In all 75 orchards were surveyed,
15 in Nashik and 60 in Solapur district during December 2005 -
July 2006.
Ganesh, Bhagwa, Phule Arakta and
Mridula were the important pomegranate cultivars grown in
Solapur and Nashik with cv. Bhagwa covering the maximum area.
Air layering (gootee) was the most
common method of propagation.
Multistem (2-4 branches) system of
training was being followed by growers and plants were kept in
proper shape through pruning.
All pomegranate orchards revealed
drip irrigation, in addition some orchards had also irrigation
channels.
Sole cropping system was more
common. Intercropping with gram ,watermelon, onion and brinjal
was also practiced in some of the orchards of 1-3 year age.
Use of FYM and NPK fertilizers was
common. However, some growers also applied neem cake at the time
of bahar treatment.
Majority of the growers practiced
Hasta bahar , while others practiced Ambe and Mrig bahars.
Analysis of soil samples, revealed
that pomegranate was cultivated in all soil types in the state
from Lithic ustortherns to typic haplustrs .
Soil pH varied between 7.6 to 8.1,
EC between 0.16 to 0.31 dS/m, organic carbon between 0.92 and
1.43 %.
Soil fertility status showed that
available N, P and K ranged from 196 to 266, 8.61 to 19.2 and
179.0 to 627.0 kg/ha, respectively while soil Micro Nutrients
Fe, Mn, Zn and Cu were present in sufficient range.
Crop Protection
Surveys of 82 pomegranate orchards
in the State were carried out to identify the major diseases ,
disorders and insect pests in the region .
Diseased samples collected during
the surveys were observed under the microscope and used for
isolating the pathogens in pure culture.
The main diseases observed during
the surveys were bacterial blight caused by Xanthomonas
axonopodis pv. punicae (upto 100.0% severity in some orchards) ,
Pomegranate wilt (70.0% severity), known to be a complex problem
due to association of abiotic ( improper drainage and heavy
soils) and biotic (association of pathogens like Fusarium
oxysporum, Rhizoctonia solani, Ceratocystis fimbriata) factors.
Other diseases of minor importance
were leaf and fruit spots ( 5-60% severity) caused by Cercospora
punicae, Colletotrichum gloeosporioides, Alternaria alternata,
and fruit rot (13.63%) caused by Rhizopus sp., and
Colletotrichum spp.)
The major disorders observed were
i) Internal breakdown of arils ii) Sun scald and iii) Fruit
cracking.
No commercially growing cultivar
was found resistant to either bacterial blight or pomegranate
wilt.
Amongst insect pests fruit borer
(Deudorix isocrates) infestation was observed in 13.6% orchards
. Stem borer (Coelosterna isocrates) and bark eating caterpillar
(Inderbela quadrinotata) were also observed in some orchards.
Besides, aphids, white flies,
mites and nematodes were prevalent in isolated orchards.
Committees:
The Centre has constituted different Committees to monitor the
functioning of the Research Centre and provide guidelines for
further strengthening its Research and Development activities.
Important Committees constituted are: -
1.
Institute Management Committee (IMC)
2.
Staff Research Committee (SRC)
3.
Research Advisory Committee (RAC)
Meetings: The Centre has successfully organized meetings of
different committees to incorporate valuable inputs for bringing
further improvement in its ongoing Research and Development
Programmes. Various meetings organized are as follows-
IMC meeting held twice in February and July 2006.
SRC meeting held in July, 2006.
RAC meeting held twice in November 2006 and February 2007.
