Abstract: |
Establishment of indeterminate
growth parameters and reproductive aspects is of crucial
importance during field conditions. Cotton plant has
particular aspects in many ways regarding its growth and
development, vegetative and reproductive as well as yield
components and field management. Although it is perennial in
its nature, it is much respondent to climate, environment,
field, soil and field preparatory practices adopted at field
level for maximum potential yield. Two year field study was
designed to carry out at the research area of CCRI, Multan
to investigate the effect of soil preparatory technique i.e.
chiseling and crop irrigation intervals in cotton field for
soil moisture holding capacity, yield of seed cotton and its
components. Cotton cultivar CIM-499 was manually dibbled on
silt loam soil in last week of May with bed and furrow
planting method duringthe both cropping years. Split plot
design was applied comprising inter culturing chiseling and
interculturing no chiseling were in main plots and
irrigation intervals (8 and days) treatments were kept in
sub plots. Results indicated that inter culturing +
chiseling produced the highest significant seed cotton
production (17.8%) more bolls plant-1 (14.3%) and water
intake (17.7%) than no chiseling with inter culturing.
However, irrigation interval after eight days produced the
maximum yield of seed cotton (14.2%), more 14.3%bolls
plant-1and water retention (35.6%) than 12 days irrigation
interval. |

Abstract: |
A pot trial was conducted in
the greenhouse of the Institute of Sustainable Agro
technology, University Malaysia Perlis, Padang Besar, Perlis,
Malaysia to analyze the influence of mungbean residue on the
properties of soil. The treatments involved three levels of
mungbean residue at three incubation periods (5%+ 1 week,
5%+ 2 weeks, 5%+ 4 weeks, 10%+ 1 week, 10%+ 2 weeks, 10%+ 4
weeks, 15%+ 1 week, 15%+ 2 weeks and 15%+ 4 weeks) and a
control treatment. The experiment was conducted within a
randomized complete block design (RCBD) with five
replicates. The collected data were analyzed using Analysis
of Variance (ANOVA) via statistical analysis system (SAS).
The measured parameters were significantly influenced
(p<0.05) by the mungbean residue treatments. The results
showed that the values of calcium, potassium, magnesium, CEC,
phosphorous, organic carbon, organic matter and carbon:
nitrogen ratio were significantly (p< 0.05) higher than that
of the control treatment. The residual effects of
mungbeanresidue significantly influence the soil nutrient
content. It can be concluded thatmungbeanresidue is
effective in increasing the fertility of the soil. |

Abstract: |
The present research was
carried out to determine the most suitable corm size of
saffron (Crocus sativus L.) in terms of saffron yield
(g/m²), corm yield (g/m²), corm number (number/plant) and
marketable corm ratio (%) during growing seasons of
2004-2005 and 2005-2006, under the Harran Plain conditions,
Sanliurfa, Turkey. The field experiments were arranged in
completely randomized block design with three replications
and 1-2 cm, 2-4 cm, 4-7 cm, 7-10 cm circumference lengths
were used as plant material. The results of study indicated
that the saffron with a large size cormwasflowered earlier
than the small corms. Large-size corms were also found to
continue to flowering for longer period than the small
corms. These findings showed that the corm size of 7-10 cm
could be suggested for saffron production but not for corm
production, due to lower marketable corm ratio (%) though
the highest corm yield (g/m²) values in small-size corm. For
corm production2-4 cm and 4-7 cm sized cormscouldbe
suggested. It was also determined that the corm sizes didnot
significantly affect the saffron quality. |
