ABSTRACT
The present investigation entitled “Effect of Morus alba on growth and yield of okra
(Abelmoschus esculentus (L.) Moh) under rainfed conditions” was carried out at experimental
field of the Department of Silviculture & Agroforestry, Dr. Y.S. Parmar University of Horticulture
and Forestry, Nauni, Solan, H.P. during the year 2016. The investigation was conducted with a view
to ascertain the effects of different organic manure combinations [T1: Recommended dose of fertilizer
(RDF) i.e NPK @ 76 kg, 57 kg and 54 kg per hectare + FYM (10 t ha-1), T2: 50% Vermicompost
(25.33 q ha-1) + 50% RDF + FYM, T3: 75% Vermicompost (38 q ha-1) +25% RDF + FYM, T4: 100%
Vermicompost (50.66 q ha-1) + FYM, T5: 50% Goat manure (12.66 q ha-1) + 50% RDF + FYM, T6:
75% Goat manure (19 q ha-1) + 25% RDF + FYM, T7: 100% Goat manure (25.33 q ha-1) + FYM, T8:
50% Poultry manure (12.54 q ha-1) + 50% RDF + FYM, T9: 75% Poultry manure (18.81 q ha-1) + 25%
RDF + FYM and T10: 100% Poultry manure (25.08 q ha-1) + FYM ] and planting conditions (1m
from tree trunk, 2m from tree trunk and open condition) on the growth and yield of okra and physicchemical
properties of soil. The experiment was laid out in a Randomized Block Design comprising
of 10 treatment combinations. All organic manure combinations had significant effect on the growth
and yield attributes of okra except plant height, inter nodal length, fruit weight and fruit volume.
Planting conditions had a significant influence on some growth and yield attributes of Okra viz;
germination, plant height, days to first flower, inter nodal length, below ground biomass, above
ground biomass, fruit length and yield per hectare but had non significant effect on number of nodes
per plant, number of fruits per plant, fruit diameter, fruit weight, fruit volume, weight of seed per fruit
and 100 seed weight. Organic manure combinations and planting conditions also had significant effect
on soil properties except on bulk density and particle density. From the present investigation it can be
concluded that T10 i.e. 100%Poultry manure (25.08 q ha-1) + FYM (10 t ha-1) under open condition
gave the best results of growth and yield attributes of Okra. However, soil physico-chemical
properties were found to be higher in plots treated with T10 at one meter distance from tree trunk.
Therefore, 100% poultry manure (25.08 q ha-1) + FYM (10 t ha-1) can be recommended to the farmers
to grow okra under agroforestry system.
