In ratoon crop of banana cv. Grande Naine, date of shooting could be advanced by 35 days with application of 200g N in 5 splits + 60g P2O5 (86 days), compared to 300g N in 5 splits + 60g P2O5 (121 days). Subsequently, date of harvest also got advanced by 53 days, and fruits were harvested on 9th December in the same treatment. Higher dose of N fertilization delayed shooting and harvesting period, taking 121 days for shooting and 145 days from shooting to harvest in the treatment 300g N (5 split doses) + 90g P2O5. Various N and P treatments affected bunch weight and number of hands per bunch significantly. Although N and P combination-treatments had no significant effect on bunch weight or number of hands per bunch, application of 200g N in 5 splits and 60g P2O5 per plant gave maximum bunch weight (18.11kg) and number of hands per bunch (10.61). Minimum bunch weight (15.37kg) and the least number of hands per bunch (7.08) were obtained with 150g N in 5 splits + 90g P2O5. Hand-weight (2.20kg), number of fingers per hand (19.75), and finger length (20.30cm) was highest with application of 200g N in 5 splits + 60g P2O5 per plant. Least hand-weight (1.64kg), number of fingers per hand (15.77), and finger-length (17.92cm) was recorded with 150g N in 5 splits + 90g P2O5. Bunch weight, number of hands per bunch, hand-weight and number of fingers per hand too was affected significantly with sole application of nitrogen or phosphorus.Keywords

To improve fruit quality in grape cv. Flame Seedless, application of Ethephon (400 and 500 ppm) and trunk girdling was done at veraison stage. Cluster thinning was done by retaining 100, 75 and 50% of total number of bunches on the vines, and, the rest were removed immediately after full bloom. Highest yield was obtained in the treatment 100% Crop load + 500ppm Ethephon, followed by 75% Crop load + 500ppm Ethephon. The treatment of 50% Crop load + 500ppm Ethephon resulted in maximum bunch weight, lowest percentage of uneven coloured berries, maximum TSS, minimum acidity and maximum TSS:acid ratio, maximum anthocyanin content, advanced maturity by 9 days and had maximum sensory rating. But, in this treatment, yield was significantly lower than in treatments where either 75% or 100% Crop load was retained. Thus, considering yield as well as quality parameters, the treatment 75% Crop load + 500ppm Ethephon was found to be the best.Keywords

The present investigation was carried out to study variability induced by gamma rays with respect to vegetative characters and LD50 dose in Rough lemon. Rough lemon seeds were gamma irradiated at doses of 0, 4, 6 and 8 kr along with control. Seed germination decreased with increasing dose of gamma radiation. Seedling height and leaf size also decreased with increasing dose of gamma radiation, whereas, apical branching, number of branches/seedling, number of variegated / albino seedlings and number of leaves increased with increasing dose of gamma radiation. Maximum variability for seedling height, number of leaves, leaf size, colour, internode length, and per cent apical branching was observed at two months from sowing in seeds treated with 8 kr dose of gamma radiation. Variability for all characters was, however, found to be minimum in the control.Keywords

An investigation was carried out to study the effect of various levels of N and P on growth and yield of banana cv. Grand Naine in first ratoon crop at Punjab Agricultural University, Ludhiana. The treatments consisted of six levels of nitrogen at 150, 200 (in 4 and 5 splits), 250 (in 4 and 5 splits) and 300 g (in 5 splits) per plant as urea, phosphorus at 60 and 90 g per plant as single super phosphate. Application of N and P at the rate of 200 g N in 5 splits + 60 g P2O5 per plant to ratoon crop of banana cv. Grand Naine proved to be the best among all treatment combinations. This also resulted in maximum plant growth, early shooting and fruit maturity. In addition, the fruit yield per plant (18.9 kg) was maximum with the above mentioned treatment. Finger length increased with increase in dose of N from 150 g to 200 g per plant.Keywords
