A field trial was carried out for two years to ascertain performance of marigold (var. Pusa Narangi) planted at three spacings and on six different dates at bimonthly interval i.e. on first day of March, May, July, September, November and January. The crop planted on 1st March showed early flowering compared to other planting dates. The best performance with respect to flower size, weight and number of flowers per plant was recorded with 1st September planting. The highest number of branches and plant canopy spread were attained with May and July plantings. In both the years wider spacing of 40 cm × 40 cm produced best results with respect to maximum flower diameter, weight of individual flower and number of flower per plant. However, the total best yield per unit area was higher when the crop was planted on 1st September at 40cm × 20 cm spacing.Keywords

The effect of foliar spray of salicylic acid (SA) and boron along with traditional growth regulators like GA3, NAA and ethephon on growth, flowering and yield of guava variety Arka Amulya was investigated. Salicylic acid 100ppm recorded maximum increase in shoot length, number of leaves and leaf area over control. The minimum day for initiation of flowering (24.33) was taken by ethephon 100 ppm spray followed by SA 200 ppm (25.33). Concerning the effect of chemicals on number of fruits per shoot and fruit set per cent, maximum numbers of fruit (3.18) per shoot and fruit set per cent (74.16) were registered in S A 100 ppm which was statistically comparable to NAA 20 ppm. However, minimum fruit set percentage (35.57) was recorded in control. GA3 50ppm and ethephon 100 ppm increased fruit length and fruit breadth, respectively over other treatments. Maximum yield (12 .30 kg) per plant was registered under treatment SA (100ppm) which found statistically comparable to NAA 20 ppm. The highest TSS and vitamin C content were registered under 20 ppm and boron 200 ppm, respectively. While, the highest B: C ratio (11.18) was recorded from the plant treated with SA 100 ppm.Keywords

Planting time is one of the effective means of improving cut flower output under open field conditions. A field experiment was carried out on gerbera with eight planting dates starting from 1st August to 15th November at fortnightly interval during 2010 to 2013. Difference in planting time produced significant difference in performance of gerbera due to variation of climatic condition. Planting on 1st September showed the best response in terms of plant height (28.35 cm), number of leaves/plant (26.2), flower diameter (11.55 cm) flower stalk length (65.52 cm), number of flower/plant/year (29.85) and number of flower/m2 (268.65) compared to rest of the planting dates. The study clearly suggested that the best planting time for gerbera under open field condition in Bihar is beginning of September.Keywords
