SHADE NET Cultivation of vegetables (2006)
Sweet
pepper and paprika crops are generally grown in hilly regions. Changes in
climatic factors especially temperature and light cause considerable variations
in growth, yield and quality characters of these crops. Of late, shade net cultivation is recommended
to grow high value horticultural crops including sweet pepper and paprika in
plains.
Farmers can grow sweet pepper and paprika cultivars
in shade net with drip irrigation as it increases not only yield but also
quality. The feasibility of raising these crops under tropical plains, during Sept-Oct
or June- July season is a boon for
vegetable growers. Further other vegetable crops such as tomato and brinjal can
be grown especially during off season.
Shade net
cultivation of sweet pepper
- The cultivar Indra recorded mean per plant yield of 19.18 kg against 5.05kg in open field.
- Each fruit weighs about 169 grams as against 72 grams in open field
- Ascorbic acid content of fruit is 129.6 mg/100 g
- Mean yield per hectare is 95.32tonnes as against 15.3 tonnes in open field.
- Benefit cost ratio was 3.85.
Shade net
cultivation of Paprika
- The cultivar Kt-pl-19 recorded 85.9 fruits per plant.
- Dry weight of single fruit was 3.64 gram as against 1.8 gram in open field.
- Yield per plant was 0.269 kg as against 0.03 kg in open field.
- Yield per hectare was 9.32 tonnes. as against 1.35tonnes in open field.
- Capsanthin content of fruit was 175.38 ASTA units as against 143.54 ASTA units.
- Benefit cost ratio was 2.66.
Nematode Management (2007)
- In rice under SRI cultivation system,
application of Pseudomonas
fluorescens as seed treatment @ 10g/kg seed and soil application @ 2.5
kg/ha reduced rice root nematodes 37.5 -
59.5 per cent and root-knot nematodes by 61.3 - 62.8 per cent in
soil and roots.
Technologies Commercialized
Acorus calamus
10d
- Repellent dust formulation constituted from Acorus calamus (sweet flag) + ash (1:9)
- Easy to formulate, eco friendly and cost effective
- Recommended dosage is 25 Kg/ha to control rice earhead bug
A Memorandum of Understanding was signed between Tamil Nadu Agricultural University (TNAU) and M/s. Bhuvicare (P) Limited, Tirunelveli to produce and sell the KKM 1 botanical insecticide Acorus calamus 10D (Developed by the PI), which was released by TNAU as a new crop protection technology in the year 2004.
The MoU was signed on July 20, 07 by Dr.P.Vivekanadan, Dean, Agricultural College and Research Institute, TNAU, Killikulam and by Th.T.G.R.Kunjharhamoney, Director, M/s. Bhuvicare (P) Limited, Tirunelveli. The MoU was announced during the Scientific Workers Conference held on July 20, 07, and it was exchanged in the presence of Th.Surjit K.Chaudhary, Agrl. Production Commissioner & Secretary to Govt., (Agri. Dept.), Dr.C.Ramasamy, Vice-Chancellor, TNAU and other dignitaries.
TNAU-made castor oil soft soaps
for pest management (2009)
Potassium
salts of fatty acids, called soft soaps, can be used to manage soft bodied
insects and mites on crops. They are eco-friendly and safe to natural enemies.
Castor oil based soft soaps developed by the Department of Plant Protection,
Agricultural College and Research Institute, Killikulam were evaluated at
laboratory, screen house and field conditions during 2007 – 2009 against
selected insects/mites on rice, cotton and vegetables. The results revealed
that they were more effective and economical than standard insecticides and
they can be used as follows:
Spray
castor oil soaps 2 and 4 @ 1.0 % at one week interval for the management of
rice leaf folder and stem borer.
Spray
castor oil soaps 2 and 4 at 1.0 % for the management of aphids and mites on
vegetables and cotton.
Spray
castor oil soaps 2 and 4 at 1.0 % for the management of aphids and mites on
vegetables.
Rice-Sweet flag inter-cropping for increasing the net return and thwarting insect pests settlement on rice (2009)
Rice-Sweet flag inter-cropping for increasing the net return and thwarting insect pests settlement on rice (2009)
 |
| Dr. S. Jeyaraj Nelson Professor (Ag.Ento.) |
- Sweet flag – one row 30x30 cm + Rice – one row -30X10cm can be adopted as the net return was maximum with minimum level of insect damage.
- Stem borer (0.7 %) and leaf folder (2.88 %) damage was significantly low with more numbers of long jawed spiders (1.67 / 10 hills) in rice-sweet flag cropping when compared to pure crop of rice
- The gross return was more (Rs. 1,21,990/-) in rice - sweet flag combinations when compared to either rice (Rs. 90,531) or sweet flag alone(Rs. 98,000) at the rate of Rs.7/Kg and Rs.16/Kg of paddy and sweet flag respectively.
