Feathered apple trees promote earlier canopy structure formation, which simplifies pruning and reduces management costs. Feathering can be induced on young fruit trees by using different cultural techniques such as pruning (head back of 1-year-old wood), limb spreading and leaf removal (youngest cupped leaves) and also by use of plant growth regula...

Apples grown often produce more fruit, but they are characterised by heavy bloom and fruit set, which results in undersized, poorly coloured, and low-quality apples. The optimal crop load, which is a quantitative measure, results in a steady annual yield and marketable fruit. Winter pruning technique, chemical thinning, hand thinning, mechanical th...

The experiment laid out in a randomized block design (factorial) had treatment combinations of three planting density, two training systems and fertigation doses of 100 and 75 per cent of AD (NPK). The results revealed that trees planted at a density of 2666 trees ha-1 registered highest annual shoot growth, increase in tree height, spread, scion g...

Foliar application of humic acid along with bio-inoculants in 4-years old inarched guava cv. Lalit in meadow orcharding system was carried out. Foliar application of humic acid @ 30 and 60 mL/L at bud burst to flowering stage and bio-inoculants (Phosphorus solubilizing bacteria (PSB) @ 10 mL/plant + Azotobacter chroococcum @ 10 g/plant, and PGPR @...

An experiment was conducted during 2017–18 to study the effect of different N, P and K doses on vegetative growth and leaf nutrient content of apple nursery plants of cultivar Starking Delicious and to find out the optimum dose of nutrients for production of healthy planting material for Merton 793 rootstock. The experiment was laid out in a rand...

Aim: To assess the effect of biostimulant and biofertilizers on soil properties and plant growth of apple nursery under eco-friendly production system. Methodology: The experiment was laid out in a randomized block design comprising 18 treatments of biostimulant, biofertilizers and their combinations. Each treatment was replicated thrice. Nursery b...

ABSTRACT The present investigation was conducted on guava cv. Lalit spaced at 2 m � 1.5 m in meadow plant-soil interface during two consecutive rainy sea�sons of 2017 and 2018. Foliar application of humic acid was carried out at bud burst stage in two different levels i.e. 30 ml/L (HA30) and 60 ml/L (HA60), bio-inoculants were applied to the rhizos...

Kiwifruit is a dioecious plant requiring cross pollination. The nectar in kiwifruit flowers is negligible which makes it less attractive to honey bees. Hand pollination is a common practice for effective pollination but this practice is inevitable, laborious and time consuming. Spraying of bee attractants during the periods of anthesis can be helpf...

The comparative performance of nano-enabled Zn fertilization against conventional Zn analogues was carried out in strawberry (Fragaria × ananassa Duch.) cv. Sweet Charlie between late September to mid-October until June for two consecutive years of 2019 and 2020. Four foliar Zn fertilizer sources viz., nano-ZnO, Zn-EDTA, ZnO and ZnSO4 were included...

Though grafting in plants is in practice since ages only limited information is available on the graft-induced morphological, biochemical and molecular variations. The mechanism(s) by which rootstocks influence scion vegetative growth and development, and vice versa, are not fully understood. Therefore, in the present investigation, we studied graf...

The present research work was conducted with an objective to study the influence of auxin on rooting and growth of rooted plants of hardwood cuttings of new apple clonal rootstock M 116.
