Title : Effect of Different Doses of ga3 and Nitrogen on Seedling Growth of Trifoliate Orange [Poncirus Trifoliata (L.) Raf.] Under Open and Plastic Tunnel Condition Material Type: printed text Authors: B. Chalise, Author ; Shrestha, R.L., Author ; Paudyal, K.P., Author ; ,Subedi, H.P., Author Pagination: 29-34 p. Languages : English (eng) Keywords: Poncirus trifoliata, Plastic tunnel, GA3, nitrogen and accelerated growth Abstract: A field experiment was conducted at National Citrus Research Program, Paripatle, Dhankuta
during 111 November, 2004 to t" September, 2005 to determine the effect of different doses of GA1
and nitrogen under open and plastic tunnel condition on growth of trifoliate orange seedling. The
experiment was laid out in two factorial split-plot design consisting three replications of each
treatment. The open and plastic tunnel was considered as the main plot factor (Factor-A) and the
combination of different doses of gibberellic acid (GAJ) and nitrogen as sub plot factor (Factor-B).
The treatments were applied in seedlings two months after germination. Seedlings were planted at
J5x/O em spacing in 90 cmx80 em sized experimental plots supplied initially with 5 kg FYM per
plot containing 48 plants. White transparent plastic sheets were used for covering the plant in the
form of tunnel. GAJ was applied as foliar spray at one month intervals while nitrogen was applied
through urea as soil application at two split doses in I'' April and I'' May. Ten sample plants were
selected for the study from each bed From the study, it was found that the growth of seedling of
trifoliate orange was highly accelerated under the plastic house condition as compared to the open
condition. The height of seedling (47.75 em). number of leaf per plant (25.27) and size of seedling
diameter (5. 193 mm) were found highest at 300 days after sowing under plastic tunnel condition.
Similarly, the highest growth of seedling height (48.8/ em), number of leaf per plant (27.20) and
seedling diameter (5.383 mm) were observed in 120 ppm GA1 and 400 kg nitrogen/ha combination
at similar age of the seedling.Effect of Different Doses of ga3 and Nitrogen on Seedling Growth of Trifoliate Orange [Poncirus Trifoliata (L.)

Title : Study on Use of Male Sterile Line for Hybrid Seed Production . in Chilli (Capsicum Annuum L.) Material Type: printed text Authors: R. Dhungel, Author ; T.R. Ghai, Author ; Kanwar, J.S., Author Pagination: 302-306 p. Languages : English (eng) Keywords: Chilli, CH-3, GA3, male sterile line, parental row ratio, urea, seed yield,
seed qualityAbstract: Field cum laboratory analysis were carried out in the Department of Vegetable Crops,
Punjab Agricultural University,· Ludhiana, during 2003-04 to evaluate effect of parental row
ratios (1:1, 2:1 and 3:1of female:male) and foliar sprays (GA3 10 and 20 ppm and urea
1and 1.5 %) on hybrid seed yield and quality of chilli obtained by using male sterile line
(MS-12). The experiment was laid out in split plot design with three replications in an
isolated plot. The experiment comprised of 15 treatments with the combination of three
parental row ratios as main plot treatments and five foliar sprays as sub-plot treatments.
Laboratory analysis for testing seed quality was done after sufficient time to break seed
dormancy. The findings revealed that the alternate row of male (S-2530) with MS-12
recorded the highest fruit set (27.33 %), fruit yield (48.80 g) per plant and seed yield (2.75
g) per plant. Nevertheless, two rows of female planted with single row of male gave
maximum seed yield per unit area (60.40 kg ha-1
) · while the quality remained at par. All the
foliar treatments significantly influenced plant height, number of fruits per plant, seed yield,
germination percentage and seed vigour over control. Foliar spray of GA3 20 ppm recorded
maximum fruit yield (49.25 g) per plant with the minimum seed yield of 45 kg ha·1
• The
highest seed yield (2.95 g) per plant and seed yield per unit area (70.16 kg ha-1
) was
recorded with the foliar spray of 1% urea. Foliar application of 1% urea_ was also effective in
significantly improving seed germination and seed vigour. Hence, it may be concluded that
maximum hybrid seed yield (89.38 kg ha-1
) of CH-3 can be produced by planting at 2:1 row
ratio of female:male parent followed by foliar spray of urea 1% at 30 and 40 days after
transplanting.Link for e-copy: http://elibrary.narc.gov.np/?r=265 Study on Use of Male Sterile Line for Hybrid Seed Production . in Chilli (Capsicum Annuum L.) [printed text] / R. Dhungel, Author ; T.R. Ghai, Author ; Kanwar, J.S., Author . - [s.d.] . - 302-306 p.
