The experiment was carried out at Horticulture Garden, Department of Fruit Science, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur (U.P.) during two subsequent years i.e., 2020 and 2021. Sixteen treatments viz., four levels of GA (0, 20, 40 and 60 ppm) and Zn (0, 0.3, 0.5 and 0.7%) were studied in a Factorial Completely Randomized Design with three replications. Spraying was done twice i.e., before flowering (07 Feb.) and at pea stage (05 April) during both the years. Application of GA 60 ppm and Zinc 0.7% increases length of new shoot (24.41 and 24.44 cm), number of leaves per shoot (23.55 and 24.06), length of panicle (34.89 and 35.96 cm), number of fruit per panicle (21.11 and 22.19), length of fruit (4.21 and 4.30 cm), diameter of fruit (4.22 and 4.29 cm), fruit weight (20.22 and 21.16 g), weight of pulp (13.69 and 13.70 g), and pulp stone ratio (4.65 and 4.62) in both respective years and reduced days required to flowering after first spray (22.13 and 21.30) days, length of seed (2.16 and 2.14 cm), diameter of seed (1.32 and 1.30 cm), weight of seed (3.20 and 3.17 g) and rind weight (2.54 and 2.52 g). We suggest that the foliar application of GA (60ppm) and Zn (0.7%) may be included in strawberry farming for profitable yields and high GA and Zn concentration in strawberry fruit in the plains of Northern India.

“…), an indigenous crop of South-East Asia, also recognized as "Queen of the fruits" is an important subtropical evergreen fruit tree belonging to the family Sapindaceae which produces sweet arillate fruits that are very succulent, juicy, aromatic and rich in vitamins and minerals.The major producing countries are China, India, Taiwan, Thailand, Myanmar, South Africa, Mauritius, Hawaii, Madagascar, Brazil, Vietnam, Pakistan, Australia, Israel and Florida (Ghosh, 2001). It was introduced in India by end of 17 th century to explore the possibilities of litchi cultivation due to the availability of convenient temperature and climatic conditions in some states of the country (Priyadarshi et al, 2018). Litchi fruits are rich in sugar contents 6.74-18.0%, acid content 0.20 to 0.64% (malic acid, citric acid, levulinic acid, phosphoric acid, glutamic acid).…”

“…India ranks 2 nd in the world from the production point of view with cultivated area expansion of 30% in the last fifteen years, it occupies about 92 thousand hectares of land with 600 thousand metric tonnes of production and productivity of 6 mt ha -1 (Anonymous, 2018). Still, Litchi suffers from widespread problem of low and irregular bearing habits, poor fruit set, heavy fruit drop, fruit cracking and poor quality (Priyadarshi et al, 2018;Stern et al, 2000). Litchi has been identified as one of the potential fruit for export in India but the yield from the litchi orchards is often low and variable (Mandal et al, 2017).…”

A field experiment was carried out at Regional Research Station, New Alluvial Zone, Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, Nadia, West Bengal, India during September 2014 to July 2017 to study the effect of different sources of potassium on fruit growth, yield and quality of Litchi cv. Bombai grown in Indo-gangetic plain of West Bengal. The experiment was laid out in Randomized Block Design consisting of seven treatments with three replications. All the plants were uniform in growth, 12 years of age and healthy spaced at 10×10 m2. The results revealed that the application of different sources of potassium significantly improved the physico-chemical qualities and leaf mineral content of litchi. Among the different sources of potassium in the study, application of KNO3 @ 2% along with fixed doses of N @ 1000 g and P2O5 @ 500 g-1 plant-1 year-1 showed maximum vegetative growth in terms of plant height (5.00 m), spread (N-S and E-W) while application of K2SO4 @ 2% along with fixed doses of N @ 1000 g and P2O5 @ 500 g plant-1 year-1 showed highest fruit retention m-2 (32.50 no), yield (72.60 kg plant-1), fruit weight (23.03 g), fruit length (4.08 cm), breadth (3.30 cm), aril weight (15.99 g), TSS (19.17 °Brix), total sugar (14.98 %), lowest reducing sugar (11.19%) with highest Vitamin C (32.83 mg 100 g-1), Anthocyanin content (38.02 mg 100 g-1)and highest mineral content (N, P, K, Ca, B and Zn) of the leaf.

“…The excessive fruit drop is a major limiting factor in litchi production (Zhao and Li, 2020). Various attempts have been made to improve fruit set and retention as well quality of the fruit with exogenous application of plant growth regulators, nutrients and pesticides (Singh and Malik, 2005;Priyadarshi et al, 2018). Fruit drop to some extent can regulate the crop for next fruiting and commercial litchi production can also be manipulated by restriction of fruit load per panicle.…”

Individual panicles produce hundreds of pistillate flowers but only a small proportion of these bear fruit and reach maturity. There are some stages of fruit drop during growth and development caused by different factors. An experimental trial was conducted in National Active Germplasm Site (NAGS) at ICAR-NRC on Litchi, Muzaffarpur, to assess the fruit drop due to different factors during 2014–2015. The result revealed that four factors viz., improper pollination and fertilization, embryo abortion, seed and fruit borer, and normal fruit abscission were associated with fruit drop in litchi and fruit drop varied from 23.53–77.54% with a maximum in Shahi and lowest in Elaichi during the first week of flowering. Fruit drop increased to 92.65–97.86% during the third week of flowering because of improper pollination and fertilization, and it reached a maximum level of 98.51–99.70% at the time of ripening stage with the lowest in Deshi. Embryo abortion was one primary cause of fruit drop during the 4th week whereas infestation of seed and fruit borer was the major factor for fruit drop during the 5–7th week. Such fruit drop can be controlled by managing the infestation of borer. Abscission due to ethylene production and heat stress during the maturity of fruit was yet another cause of fruit drop. This study will help to researcher to find out the time of infestation of seed and fruit borer which causes heavy fruit drop and it can be controlled with pest management option.
