Growth and Yield of Summer Tomato as Influenced by Plant Growth Regulators
نویسندگان
چکیده
A field experiment was carried out at Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh, to assess the effect of different plant growth regulators on tomato during summer season 2011. Different plant growth regulators (PGR) viz. PGR = Control, PGR = 4-CPA (4-chloro phenoxy 0 1 acetic acid) @ 20 ppm, PGR = GA (Gibberellic Acid) @ 20 ppm and PGR = 4-CPA + GA3 @ 20 ppm of each 2 3 3 were used in the study. The growth and yield contributing characters were significantly differed due to different plant growth regulators. The maximum plant height at 60 DAT (86.01cm), number of flowers cluster per plant (10.60), number of flowers per plant (39.69), number of fruits per plant (36.54), single fruit weight (74.01 g) and yield (28.40 t ha ) were found in PGR and the minimum for all the parameters were found in control (PGR ) 1 3 0 treatment.

Beneficial effect of titanium on plant growth, photosynthesis and nutrient trait of tomato cv. Foria
ABSTRACT- Titanium is a beneficial element for plant since its promotive effect on plant metabolism has been well documented. However, the physiological role of this trace element in tomato is not clear. This experiment was conducted as a complete randomized design to study two concentrations of titanium (1 and 2 mg/L Ti) and 0 as control on physiological and nutrient properties of tomato cv. F...
متن کاملSunflower morphology and yield as affected by foliar applications of plant growth regulators
Plant height of sunflower is a major agronomic trait affecting crop performance in the field and its adaptation to mechanical harvest. Field experiments were conducted to study the effect of foliar application of paclobutrazol (PBZ) at 12.5 g ai/ha, mepiquat chloride (MPC) at 25.0 g ai/ha and chlormequat chloride (CCC) at 1,500 g ai/ha in single or double applications on sunflower plant mor...

The effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (Lycopersicon esculentum L.) were investigated in Gorgan, Iran. A factorial experiment was conducted based on RCBD with four NaCl levels (0, 50, 100, and 150 mM) and four CaCl2 levels (0, 100, 200 and 300 mg L-1). Data of growth, yield and leaf’s Ca, K, and Na content were subjected to analyze ...
