Yield And Quality

The effect of different plant growth regulators on flowering, fruiting, yield, and quality of pomegranate (Punica granatum L.) cv. Bhagwa was studied in a field trial at ICAR - Indian Institute of Horticultural Research (IIHR), Bengaluru, during two seasons, namely ambe bahar (January–February) 2016 and hastha bahar (September–October) 2016-17. Nitrobenzene (NB) 1.0, 1.5, and 2.0 ml plant-1, Cycocel (CCC)  500, 1000, and 1500 ppm plant-1, Uracil  25 and 50 ppm plant-1, CCC  1000 ppm + Uracil  25 ppm plant-1, CCC  1500 ppm + Uracil  50 ppm plant-1, and Control were among the eleven treatments studied. The application of uracil  50 ppm plant-1 resulted in a higher number of hermaphrodite flowers plant-1 (264.7), number of fruits plant-1 (154.0), and fruit yield (27.1 kg/plant). Fruit weight (197.6 g), fruit length (6.64 cm), total aril weight (113.63 g), 100 aril weight (27.18 g), fruit juice weight (101.94 g), TSS content (19.96 OB), fruit anthocyanin content (6.46 mg 100 g) and low titrable acidity (0.41 percent) were recorded when CCC  1000 ppm + Uracil  25 ppm plant-1 was applied. During ambe bahar, the highest fruit width (6.90 cm) and volume (162.7 ml) were observed with CCC  1000 ppm and 1500 ppm plant-1, respectively. During hastha bahar, CCC  1500 ppm plant-1 resulted in a higher number of hermaphrodite flowers (287.8), the highest percentage of fruit set (86.10), the highest number of fruits plant-1 (156.66), the highest fruit yield (54.53 kg plant-1), the highest fruit weight (348.32 g), the longest fruit length (8.53 cm), and the largest fruit volume (8.53 cm) (33.93 ml), total aril weight (224.01 g), 100 aril weight (35.09 g), fruit juice weight (119.40 g) and TSS content (16.00 OB). A foliar spray of nitrobenzene  1.5 ml plant-1 compounded the high fruit anthocyanin content (6.47 mg 100g-1). As a result of the research, it can be concluded that CCC  1000 ppm + Uracil  25 ppm plant-1and CCC  1500 ppm plant-1were the most effective treatments for improving floral characters, fruiting, yield, and quality in pomegranate cv. Bhagwa during both seasons.

ABSTRACT Plant growth regulators can influence fruit yield and quality. This study aimed to evaluate the effect of cytokinin and gibberelin on the agronomic and physicochemical characteristics of banana fruits cv. ‘Prata’ (Musa spp. AAB), according to the formation period and position in the bunch. The experiment was conducted in a completely randomized 2 x 5 factorial design, two periods of bunch development (summer and winter), five treatments and ten replicates. To study the effect of position in the bunch, split plot was adopted, considering in the plot, 2 x 5 factorial and in subplots, hand 1, hand 4 and last hand. Treatments consisted of 2 pulverizations with water, 150 mg L-1 cytokinin, 200 mg L-1 of gibberellic acid, 100 mg L-1 of cytokinin plus 200 mg L-1 of gibberellic acid and 200 mg L-1 of cytokinin plus 200 mg L-1 of gibberellic acid, applied from the fourth to the last hand of the bunch. Cytokinin and gibberellin, alone or associated, regardless of formation period and position, did not affect the size and physicochemical characteristics of fruits, only delayed the bunch harvest.

Irrigation Levels

An experiment was conducted during the winter season of 2017-18 at College of agriculture, Bikaner to study the effect of irrigation levels and plant growth regulators on Cucumber under naturally ventilated Poly house condition. The experiment was laid out in split plot design with three replications. The treatments comprised of four drip irrigation levels (0.4, 0.6, 0.8 and 1.0 ETc or crop evapotranspiration) assigned to main plots and three plant growth regulators viz; water spray, NAA or Naphthalene Acetic acid (100 ppm) and GA3 (50 ppm) assigned to sub plots. The objectives of this study were to find out the effects of irrigation levels as well as plant growth regulators on yield attributes of cucumber and their interactions. Results indicated that earliness i.e. days to first flowering (35.40) and first harvest (52.00) were recorded maximum with 1.0 ETc as compared to other irrigation levels. The same treatment (1.0 ETc) significantly gave maximum fruit length (21.07 cm), number of fruits per vine (12.02), fruit weight (103.29 g), fruit yield (728.76 q ha-1) and net returns (765035.9 ha-1) with B:C ratio (2.46). However, water use efficiency (3.61 q ha-1 cm-1) was found maximum with 0.4 ETc. Among various plant growth regulators GA3 (50 ppm) recorded significantly higher yield attributes namely fruit length (21.63 cm), number of fruits per vine (12.34), fruit weight (99.48 g) and fruit yield (729.23 q ha-1). Water use efficiency, net returns and B:C ratio also exhibited higher values (2.57 q ha-1 cm-1, 765307.7ha-1 and 2.46, respectively) with same treatment. Similarly, earliness i.e. days to first flowering (34.19) and days to first harvest (50.70) were recorded with GA3. The treatment combination 0.8 ETc + GA3 (50 ppm) gave maximum value for fruit yield (793.93 q ha-1) per hectare.

The Impact

An experiment was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh to test the impact of plant growth regulators on growth and yield of summer tomato. The experiment consisted of two tomato varieties viz. BARI Hybrid Tomato-4 and BARI Hybrid Tomato-8 and four types of plant growth regulator (PGR)viz.,(i) control (without PGR), (ii) 4-CPA (4-chlorophenoxy acetic acid), GA3 (gibberellic acid) and 4-CPA +GA3. The two-factor experiment was laid out in randomized complete block design with three replications. The results of the experiment revealed that significant variations were observed for most of the characters studied. At 75 DAT, the tallest plant (79.35 cm), number of flowers and fruits (38.11 and 19.04, respectively) plant-1, individual weight (58.44 g) and fruit yield (22.75 t ha-1) were found in BARI Hybrid Tomato-8.At 75 DAT the maximum plant height (87.90 cm), number of flowers and fruits (49.04 and 21.9, respectively) plant-1, individual fruit weight (61.16 g), and fruit yield (27.28 tha-1) were found when 4-CPA + GA3 applied together, whereas the minimum for these characters were recorded from control plants. In case of combined effect of variety and plant growth regulator, the maximum plant height (87.90 cm), number of flowers and fruits (49.04 and 21.91, respectively) plant-1, individual fruit weight (61.16 g) and fruit yield (27.28 t ha-1) were observed in BARI Hybrid Tomato-8 when treated with 4-CPA + GA3together, and the minimum for all these parameters were found in control plants. The results of the present study suggest thatboth 4-CAP and GA3together can be practiced for increasing summer tomato production for both the varieties.Progressive Agriculture 26:32-37, 2015

The aim of the present work was to evaluate the effects of auxins and gibberellins when applied at pre-harvest to the fruit development, and to the ripening and natural fall of the fruit, in 'Pêra' oranges. Trees of Citrus sinensis Osbeck cv. Pêra, 5 years old, were utilized. The treatments applied were: GA3 + 2,4-D 12.5mg L-1 of each; GA3 + 2,4-D 25mg L-1 ; GA3 + 2,4-D 37.5mg L-1; GA3 + NAA 12.5mg L-1; GA3 + NAA 25mg L-1; GA3 + NAA 37.5mg L-1; NAA + 2,4-D 12.5mg L-1; NAA + 2,4-D 25mg L-1; NAA + 2,4-D 37.5mg L-1; and water (control). The treatments were applied 3 times, at intervals of 45 days. The variables evaluated were: rate of natural fall (%), fruit length and diameter (mm), and fresh fruit weight (g). None of the treatments promoved alterations in the development of the fruits, but they did reduce the natural fall rate, when compared to control, up to 78.05%, inhibiting the fruits' abscision as much as 3 months.

Abstract: The objective of this work was to investigate the effect of plant growth regulators for enhancing fruit color of 'Gala Standard' apples (Malus domestica). The experiment was carried out in the 2015 and 2016 crop seasons. The treatments consisted of water, as a control; 300 mg L-1 ethephon, as a positive control; 400 mg L-1 prohydrojasmonate; and 400 mg L-1 abscisic acid. Flesh firmness, soluble solids content, fruit weight, and red color were assessed after harvest. Plant growth regulators enhanced red color of fruit and chlorophyll degradation. Prohydrojasmonate and abscisic acid did not reduce flesh firmness, in the 2016 season.
