Abstract: |
To check genetic variability,
heritability and genetic advance in F4 wheat lines a field
experiment was designed at the University of Agriculture
Peshawar, during 2015-16. Eleven genotypes (10 F4 lines and
one check) were studied in randomized block design using
three replications. Data noted on parameters included days
to heading, plant height, flag leaf area, spike length,
grain weight spike-1, 1000-grain weight, grain yield
plant-1, biological yield plant-1and harvest index.
Significant difference was statistically detected for all
the traits. High magnitude of heritability (˃0.62)
was noted for all parameters except spike length (0.57)
which was moderate. Low expected genetic advance was
recorded for days to heading (3.90%) and spike length
(8.13%), moderate expected genetic advance was observed for
plant height (9.95%), grain weight spike-1 (11.54%) and 1000
grain weight (13.41%), while high expected genetic advance
was noted for flag leaf area (24.72%), grain yield plant-1
(20.45%), biological yield plant-1 (23.64%) and harvest
index (24%). Grain yield plant-1 exhibited positively
genotypic and phenotypic correlation with days to heading,
plant height, flag leaf area, spike length, grain weight
spike-1, 1000-grain weight, grain yield plant-1, biological
yield plant-1and harvest index. Strong correlation of grain
yield plant-1 with these traits showed that these traits
could be safely used in future breeding program. |

Title: |

Abstract: |
A field experiment was
conducted to assess the effect of iron (Fe) and molybdenum
(Mo) on yield and nodulation of lentil (Lens culinaris
Medic) at Agriculture Research Farm (N) Mingora Swat during
2014 - 2015. The experiment was laid out in a randomized
complete block design (RCBD) with three replications. Basal
dose of NPK @ (20-60-60 kg ha-1) were applied to
the entire treatments plot in the form urea, SSP and SOP.
Iron was applied at the rate of 0.5 and 1.0 kg ha-1
in the form of ferrous sulphate (FeSO4.7H2O)
and molybdenum was applied at the rate of 0.05 and 0.10 kg
ha-1 in the form of ammonium molybdate {(NH4)6Mo
O24.4H2O)} as foliar spray. The
results showed that application of iron and molybdenum
significantly increased the grain yield, biomass yield,
harvest index (%), 1000 seed weight (g), total N uptake,
protein content, number of total and active nodules plant-1.
It was observed that combined application of iron and
molybdenum significantly produced greater crop yields and
more nodulation than the sole application of iron or
molybdenum. These results suggested that combined
application of iron @ 1.0 kg ha-1 and molybdenum
@ 0.10 kg ha-1 as foliar spray significantly
enhanced the crop yields and root nodulation in lentil under
the agro-climatic conditions of Swat valley. It is therefore
recommended that Fe and Mo may be applied to lentil in Swat
valley for better crop yields and greater root nodulation. |

Abstract: |
To investigate the element
properties of Ficus wood growing in Iraq, this experiment
has conducted on two species of the genus planted in Baghdad
region. Wood specimens were taken from five trees
representing each of F. nitidaand F. religiosa. Specimens
offered wood resembling four height levels and two radial
positions (outer and inner). Wood samples were separated
according to treatment combination, macerated and tested
microscopically. Three properties were investigated (fiber
length, fiber wall thickness, and vessel diameter). Results
showed that the two species had around the same fiber
length, but with wall thickness and vessel diameter F.
religiosawas the superior. Little addition was found in
fiber length of wood near to bark compared to inner wood.
Longitudinally, fiber length and vessel diameter were
increased as the height increased up to the third level
after which declining in dimension has occurred. |

Title: |
Fuzzy logic based
greenhouse climate control for tomato production |

Abstract: |
A fuzzy logic based Greenhouse
climate control is presented in this research. Primarily
seven most important greenhouse climate parameters affect
tomato production are considered soil type, plant water use
capability, plant root depth, temperature, humidity,
irrigation quantity required for crop grow and light day.
Manual tomato crop data input, actuator and sensor nodes has
been managed by fuzzy logic controller which mimics the
brain of the planter to provide reliable, power conserving
and autonomous control system of a greenhouse. Contrarily,
the conventional control methods are not efficient in terms
of energy, labor interference, productivity and flexibility.
In this research, the adoption of artificial intelligent
(AI) approach to controlling tasks within greenhouse is
presented. Fuzzy inference system has been designed and
fused within the coordinator node of real time sensors;
simulation of nodes and actuators has been presented. The
proposed fuzzy controller of tomato crops proves high
efficiently, cost effective method, beside flexibility of
tuning the whole system for other agricultural tasks. |
