Sustainable management of soil moisture, nutrient availability and microbial activity is important for maintaining the growth, productivity and fruit quality of Daisy mandarin. Mulching and biological inputs such as Jeevamrit and Panchgavya may improve the soil microenvironment; however, their combined effects on Daisy mandarin growth, yield, fruit quality and soil characteristics require evaluation. The present study was carried out at the College of Horticulture and Forestry, Neri, Hamirpur (H.P.), during 2024-2025. The experiment was laid out in a factorial randomised block design with three replications. The study comprised twelve treatments involving different types of mulching materials, viz. M0: no mulch, M1: grass mulch, M2: black polythene mulch and M3: mulch mat, and three biostimulant treatments: B0: no biostimulants, B1: Jeevamrit @ 10% and B2: Panchgavya @ 5%, either alone or in combination. The results showed that vegetative growth, flowering, yield, fruit quality, soil nutrient status and microbial populations were significantly enhanced under M1B1 (grass mulch + Jeevamrit @ 10%). The maximum increase in plant height (64.10 cm), maximum number of fruits (62.00/plant) and highest yield (12.52 kg/plant) were observed under M1B1 (grass mulch + Jeevamrit @ 10%). Biochemical parameters such as TSS, total sugars and ascorbic acid content were highest under M1B1 (grass mulch + Jeevamrit @ 10%). The highest soil organic carbon (1.52%), available soil nitrogen (274.90 kg/ha), available soil potassium (243.03 kg/ha) and total microbial count (1.64× 108 cfu g-1) were recorded under M1B1 (grass mulch + Jeevamrit @ 10%). Therefore, M1B1 (grass mulch + Jeevamrit @ 10%) can be regarded as the best treatment in the present study.

An experiment was conducted during 2025 at the Department of Fruit Science, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.), to assess in the enhancement of yield and quality attributes of litchi through the foliar application of NAA, Boron, and Zinc Sulphate. Nine treatments comprising two concentrations of NAA (40 and 60 ppm), three concentrations of boron (0.4, 0.6, and 0.8%), three concentrations of ZnSO4 (0.6, 0.8, and 1.0%), and one control were evaluated in a Randomised Block Design with three replications. Foliar sprays were done twice, once before flowering and again at the pea stage of fruit development. Significant differences were observed among treatments. NAA @ 40 ppm recorded highest fruit set (57.46%), lowest fruit drop (61.28%), and highest fruit retention (33.82%). However, Boron @ 0.6% proved superior in improving fruit quality and yield by recording minimum fruit cracking (7.95%), maximum fruit length (4.62 cm), fruit diameter (3.90 cm), fruit weight (20.00 g), pulp weight (16.42 g), TSS (22.55 °Brix), total sugars (18.52%), vitamin C (25.36 mg/100 g), pulp: stone ratio (5.97) and fruit yield (25.31 kg plant-1), with minimum seed weight (2.75 g) and titratable acidity (0.35%). Therefore, a foliar application of boron at 0.6% is recommended to improve yield and quality of litchi cv. Dehradun under the plains of northern India.

Overall, transcription factors from the DREB, NAC, MYB, and WRKY families are still considered the primary regulatory targets, but CRISPR/Cas-based gene editing is now able to provide precise, multiplex gene modifications in polyploid wheat.
