The growth and flowering of ‘Rupert’ and ‘Ronina’ lachenalia (Lachenalia) in a greenhouse environment were manipulated by varying planting times and flurprimidol treatments. Bulbs were planted in November, December, January, and February. At each planting date, the following flurprimidol treatments were tested: soaking the bulbs before planting (15 and 30 mg·L−1) or a single foliar spray (15, 30, 45, and 60 mg·L−1). The results showed that foliar application of flurprimidol was ineffective in controlling inflorescence stem height and inflorescence length; only soaking bulbs of ‘Rupert’ in flurprimidol at the concentration of 30 mg·L−1 shortened the inflorescence stem height. Moreover, soaking bulbs in the concentration of 30 mg·L−1 may be recommended for potted lachenalia production, as shorter and wider leaves were obtained and every planted bulb emerged and flowered. The later the date of planting of the bulbs, the more quickly the plants began to flower. As planting time was delayed, inflorescence stem length and leaf length decreased, and the number of florets and leaf width increased. Soaking the bulbs in the retardant (30 mg·L−1) delayed the emergence of flowers for 5–6 days, but the retardant did not affect the number of leaves or the number of florets per inflorescence. Regardless of the factors applied, the two cultivars of lachenalia differed with respect to each of the analyzed traits.

Commercially available foliar spray labeled as ‘Planto-fuel’ increased significantly (p ≤ 0.05) most of the growth traits viz., leaf length, bulb diameter (7.6 cm), bulb length (5.9 cm), leaves fresh weight/plant, neck fresh weight/plant, bulb fresh weight/plant (166.6 g) and plant fresh weight. It also produced the maximum yield (14.2 tons/ha) while the basal application of DAP significantly increased the number of leaves/plant and 2nd best results in yield whereas the lowest yield was observed through water spray. It is observed that the foliar application of micronutrients mixture in combination with nitrogen is the most suitable method to increase the onion production.

An experiment was conducted with a local cultivar of garlic to study the effects of planting date and gibberellic acid on the growth and yield of garlic at the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during November 2001 to April 2002. Early planting influenced the plant height, leaf number, bulb diameter and total dry matter. With the delay in planting time starting from November 7, the yield was chronologically reduced in later plantings. Significantly the highest bulb yield (2.67 t/ha) was recorded when planting was done on November 7 and lowest yield (0.92 t/ha) was obtained from December 22 planted crop. Bulb yield was higher in control plants than those of GA3 treated plants. The interaction effects of planting date and different concentrations of GA3 differed significantly in respect of plant height, number of leaves, bulb diameter and dry weight of roots, leaves and bulbs and yield of garlic.

This study aims to determine the growth response of the love wave plant (Anthurium plowmanii) on Petrovita leaf fertilizer in an advanced nursery conducted in August - October 2011 in Panarung Village, Pahandut District, Palangka Raya City. Single treatment design (one factor) with 10 (ten) repetitions in the form of Petrovita leaf fertilizer (D) consisting of 5 concentration levels, namely: d1 = 0.5 ml l-1 (0.05%); d2 = 1.0 ml l-1 (0.10%); d3 = 1.5 ml l-1 (0.15%); d4 = 2.0 ml l-1 (0.20%); and d5 = 2.5 ml l-1 (0.25%) using a completely randomized design. Observations were made when the plants in the advanced nurseries had received treatment applications 4 times at intervals of 2 weeks. Observations were made on plant height (cm); stem height (cm); number of leaves (leaves); leaf length (cm); leaf width (cm); and leaf area (cm2). The results of this study indicate that Petrovita complete leaf fertilizer has a very significant effect on increasing the growth of love wave plants aged 8 MST in advanced nurseries. Petrovita fertilizer concentration of 0.2% or 2 ml l-1 (d4) is the best and most efficient treatment for love wave plants in advanced nurseries. It is recommended to increase the growth of love wave plants in advanced nurseries using Petrovita 0.2% concentration but tried with an interval of less than 2 weeks (for example once a week).

Micronutrients applications are effective for better crop production in calcareous soils because these soils are usually deficit in iron (Fe), zinc (Zn) and boron (B). In Pakistan, most of soils are calcareous in nature. When tuberose is grown in such soils as a cut flower, its production is negatively affected. Therefore, a study was aimed to evaluate the effects of micronutrients as foliar sprays on cut tuberose production in calcareous soil. Micronutrients (Fe, Zn and B) alone and in combinations were sprayed on the plants after 60, 90 and 120 days of planting. The mixture of all these three micronutrients increased the plant height (95.77 cm), chlorophyll content (38.13 SPAD), number of leaves (79.63), leaf length (44.73 cm), fresh (111.64 g) and dry (16.16 g) plant weights, root length (15.13 cm), number of stalks (3.73), stalk length (79.03 cm), spike length (22 cm), number of florets (51.67), floret fresh weight (11.85 g), leaf Zn concentration (53.6 mg/g) and vase life (8.4 days). Fe + Zn enhanced the number of leaves (76.60), leaf length (45.83 cm), root length (15.05 cm), spike length (22.33 cm), and leaf Fe (128.18 mg/g) and Zn concentrations (55.02 mg/g). The Fe spray increased the leaf length (44.10 cm), days to flower initiation (142.47 days) and leaf Fe concentration (130.75 mg/g) in tuberose plants. Application of Zn improved the leaf length (45.87 cm) and diameter (1.32 cm), root (15.03 cm), spike (21.77 cm) and floret lengths (4.74 cm), floret dry weight (1.49 g) and leaf Zn concentration (57.5 mg/g). Foliar spray of B increased the B concentration (21.1 mg/g) in tuberose leaves. It is concluded that foliar application of micronutrients alone and in combinations improved the plant growth, flowering, leaf minerals concentrations and vase life of tuberose spikes. However, mixture of Fe, Zn and B was more effective as compared to other treatments. Moreover, current study encourages the foliar application of micronutrients in tuberose when grown in calcareous soils.

To study the effect of rationalizing irrigation and mepiquat chloride foliar application on growth, productivity and fruit quality of Florida Brines peach trees grafted on Nimagard root stock and grown in sandy soil at a private orchard in El- Tahadi road, EL-Behara Governorate, Egypt. A trial in a split plot design has carried out through two successive seasons of 2018 and 2019. Three drip irrigation levels (100, 80 and 60 % of ETc) were in the main plot and mepiquat chloride foliar application by three levels (without, 150 and 300 ppm) in sub plot and all trees had fertilized by recommended doses. Results indicated that shoot length (cm) and number of leaves/ shoot was not significantly affect by the three irrigation levels in both seasons. Reducing irrigation increased acidity of peach fruits and led to a significant reduction on leaf area (cm)2, total chlorophyll contents, yield, fruit weight, flesh weight, seed weight, TSS and total sugars but no significant difference between irrigation by 80 or 60 % from calculated ETc except with yield and seed weight in both studied seasons. Number of leaves/ shoot, yield either kg/tree or ton/feddan and fruit flesh thickness (cm) were not significantly affected by mepiquat chloride foliar application at all concentrations in both seasons. The highest fruit TSS and the lowest shoot length (cm), leaf length and width (cm), leaf area (cm2) and total fruit acidity were obtained from peach trees treated by mepiquat chloride foliar application at 300 ppm but by mepiquat chloride foliar application at150ppm achieved the highest increase in fruit weight (gr), flesh weight (gr) and fruit total sugars in both seasons. Additionally, the obtained data from the interaction between irrigation levels and mepiquat chloride foliar application showed that mepiquat chloride foliar application made the decrease in irrigation level gave no significantly reduction in shoot length, leaf length and width (cm), leaf area (cm2) especially with concentration 150 ppm and with 300 ppm on leaf total chlorophyll contents. However, this interaction failed to show a clear trend on others studied parameters in both seasons. In addition, peach leaf anatomy has affected by foliar application with mepiquat chloride at 150 ppm and 300 ppm where a prominent increase in thickness of lamina of leaf blade more than those of unsprayed ones (control) has found. Finally, irrigated peach trees by 60% of calculated ETc led to the highest water saving and gave the highest productivity of irrigation water where every used m3 water gave (4.83 & 5.33 kg peach fruits).

A field experiment was carried out to screen the best foliar concentration of salicylic acid (SA) out of 25, 50, 75 and 100 mg L-1 for its effect on various growth and yield parameters like number of leaves, plant height, number of fruits plant-1, fruit dimensions, leaf chlorophyll content and yield plant-1 in three chilli cultivars. The selected chilli cultivars included were Sky-Land-II, Sky-Land and 1130. The experiment was conducted in field area of the Department of Horticultural Sciences, The Islamia University of Bahawalpur, Pakistan during 2017. Results indicated that different levels of SA significantly increased plant growth and yield parameters, but the level of SA @ 75 mg L-1 highly improved the studied parameters in selected cultivars. Moreover, foliar spray of SA significantly increased growth in selected cultivars; however, Sky-Land-II performed better in response to different concentrations of SA. In conclusion, foliar spraying of 75 mg L-1 SA could be recommended to chilli growers under arid region of Bahawalpur for growing cultivar Sky-Land-II.
