Acid lime (Citrus aurantifolia Swingle) belongs to the family Rutaceae and widely grown in tropical and subtropical regions of India. Fruits are rich in vitamin C, minerals and salts. Micronutrients such as Zinc, Iron and boron play a vital role in acid lime for growth and development. Generally, acid lime is micronutrient loving plant hence application of micornutrients considerably increases flowering, fruit set and fruit quality and reduces fruit drop. With this background, the present experiment was conducted at find out optimum levels of foliar application of micronutrients on growth, yield and fruit quality of acid lime var. PKM-1 at Citrus Research Station (TNAU), Sankarankovil, Tirunelveli district, Tamil Nadu during 2019-2020. Foliar application was given twice in a season viz., the first spray at at peak flowering stage and next spray during fruit set stage on selected five trees for each treatment at farmer's field. The trial was laid out in a randomized block design (RBD) with thirteen treatments and replicated thrice. The present study results revealed that T12 (1.0% Ferrous sulphate + 1.0% Zinc sulphate + 1.0% Copper sulphate + 1.0% Manganese sulphate + 0.3% borax) recorded the highest values of growth, yield and quality traits such as plant height (3.90 m), tree spread (4.70 m) (5.05 cm), number of fruits per plant (612.20), fruit weight (42.80 g), fruit girth (4.95 cm), fruit volume (40.10 cc) and yield per plant (15.08 kg/tree) and quality traits viz., TSS (6.53 o Brix), juice content (35.50 ml), ascorbic acid content (33.30 mg/100g), acidity (8.90%) and B:C ratio (2.10) and followed by T11 (0.5% Ferrous sulphate + 0.5% Zinc sulphate + .5% Copper sulphate + 0.5% Manganese sulphate + 0.1% borax) whereas the lowest values was observed in control (T13).

Calcareous and alkaline nature of soil hinders smooth up take of micronutrient from soil. Hence, the impact of foliar feeding of micronutrients (Zn, Fe, B, Cu) in different combinations on growth, yield and quality of sweet orange cv. Mosambi in a non-conventional citrus growing area was evaluated. Results revealed that treatment combination of Zn @ 0.5% + Fe @ 0.2% + B @ 0.3% + Cu @ 0.1% (T9) followed by B @ 0.3% + Fe @ 0.2% (T6) and Zn @ 0.5% + B @ 0.3% (T7) was most effective for improving growth of Mosambi plants in terms of shoot length, leaf number, leaf area as well as photosynthetic efficiency of the plant. The yield per plant was also obtained maximum in T9 (14.94 kg). Further, fruit quality attributes in terms of TSS, total sugar, flavonoids, ascorbic acid content as well as antioxidant capacity of the fruit were recorded maximum in T9 with at par result in T6. Therefore, three foliar spray of Zn @ 0.5% + Fe @ 0.2% + B @ 0.3% + Cu @ 0.1% from May-July can be recommended to...

The present investigation was carried out at during 2008-09 growing seasons to study the effect of foliar application of bio-regulators and nutrients on growth and yield of lemon (Citrus limon Burma.) cv. Pant Lemon-1. On the basis of overall performance of treatments on growth and yield characters of fruits, it can be concluded that the maximum values for fruit set (3.12%), days to maturity (148.23), yield of fruits (39.25kg) per plant have been obtained maximum with minimum fruit drop (33.58%) under GA 3 (20 ppm), minimum fruit cracking was found under NAA 50 ppm, while minimum number of seeds (10.48) per fruit and minimum seed weight (0.580gm) per fruit under GA 3 (10 ppm) treatment. However, the maximum number of fruits (403.27) per plant and maximum pulp:seed ratio (20.89) was recorded under NAA (10 ppm) foliar application.

The present investigation was carried out for two consecutive years of 2017 and 2018 at Horticulture Research Station, Bidhan Chandra Krishi Viswavidyalaya, Mondouri, Nadia to study the effect of micronutrients on fruit set, yield and quality of sweet orange (Citrus sinensis Osbeck) cv. Mosambi in the Gangetic alluvial region of West Bengal. The experiment was laid out in RBD, replicated 3 times with seven treatments, viz., Boric acid @ 0.2 & 0.4%, Zinc sulphate (ZnSO4) @ 0.3 & 0.6%; Copper sulphate (CuSO4) @ 0.2 & 0.4% and control (water spray only) and imposed two times as foliar spray- 1st at onset of flowering and 2nd at 30 days after 1st spray on 4 years old sweet orange plants cv. Mosambi. The results revealed that, application of ZnSO4 @ 0.6%, followed by ZnSO4 @ 0.3% significantly improved fruit retention percent (20.43% and 18.46%, respectively) over control (12.35%). The highest fruit yield was obtained with foliar application of ZnSO4 @ 0.6% (33.93 kg/ha), followed by ZnS...

The present investigation was conducted at the farm of Department of Fruit Science, VCSG Uttarakhand University of Horticulture and Forestry Bharsar, Pauri Garhwal, Uttarakhand during 2016-17, to study the effect of foliar spray of Zn, Cu and B on growth, yield and fruit quality of sweet orange (Citrus sinensis L.) cv. Mosambi. The experiment was laid out in Randomized Complete Block Design with ten treatments and three replications. Based on the result obtained from the present investigations, it was observed that the highest annual shoot growth and leaf area were observed with treatment T8 [Zn (0.5%) + B (0.7%) + Cu (0.5%)], while fruit set, fruit weight, fruit length, fruit breadth, fruit volume, fruit yield/plant and estimate yield (tonnes/ha.) were recorded highest with the treatment T10 [Zn (0.5%) + B (0.7%) + Cu (0.7%)]. Hence, it was concluded that the micronutrients spray in treatment T10 [Zn (0.5%) + B (0.7%) + Cu (0.7%)] was found most effective in improving the yield and...
