ABSTRACT
A field experiment was conducted at the New Developmental Research Farm, the University
of Agriculture Peshawar during rabi season 2016-17. A wheat variety Ata-Habib was
selected to check its performance by adopting methods of sowing and mixed tank herbicides
application. The experiment was arranged in split-plot with randomized complete block
(RCB) design with 4 replications. For practical adaptation of the experiment, the sowing
methods were allotted as the main plots, while tank mixed herbicides were kept in the subplots
to get prominent results for the possible positive differences among the treatments.
The sub-plot size measured as 1.5 X 3 m while row to row distance was kept 30 cm. Data
were recorded on weed density m-2, fresh and dry weed biomass (kg) , plant height (cm),
spike length (cm), leaf area (cm), number of tillers (m-2), number of grains spike-1, 1000
grain weight (g), biological yield (kg ha-1) and grain yield (kg ha-1), Harvest index (%).
These data parameters were formally observed with great care to avoid any repetition or
error of the data. Noxious weeds were observed and recorded in the field viz. Avena fatua,
Anagallis arvensis, Euphorbia helioscopia, Phalaris minor, Poa annua, Medicago denticulata,
Convolvulus arvensis, Coronopus didymus, Fumaria polymorpha, Melilotus parviflora,
Chenopodium album and Rumex crispus. The obtained results indicated that sowing
methods were statistically significant for plant height, grains spike-1,1000grain weight and
biological yield that showed a clear effectiveness of the recorded data parameters. In
addition to this, herbicides applications were also statistically significant for all the
parameters except grains spike-1, while the interaction of sowing methods and herbicides
application were also non-significant. In sowing methods, line sowing provided satisfactory
results. As general understandings various weeds were managed significantly through tank
mixed herbicide applications with a ratio of 60-72% for broad leaf and grassy weeds
respectively. Consequently the instant results provided 54% increased yield compared to
the untreated treatments. Hence it is concluded that, line sowing in combination with tank
mixed herbicides are more suitable for management of weeds in the wheat field and
increased yield in the agro-climatic conditions of Peshawar-Pakistan.
