Bernas SM, Fitriana M, Wijaya A, Fitri SNA. 2020. Effect of the seedling age and compost to the growth of palm date lulu (Phoenix Dactylifera L.) nursery and investigation of female seedling. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 199-207.Indonesia imported very high amount of date palm fruits about 9.99 million kg or US$ 13.18 M, because of that it is necessary to develop a research about date palm seedling nursery and investigation of female date, since this is a dioecious plant. The aim of this investigation was to find out characteristics of female date seedling and the effects of seedling age and compost on seedling growth. There were 2 steps in this research: the first was application of compost on seedling (without and plus compost treatments) and the age of seedling (15 and 30 days old) for transplanting into polybag, the growth ability of plant was monitored. The second step was transplanting seedling at 30 days old into pan for investigation female date, which 20 seedlings were planted in one pan and replicated 3 times.  Results showed that compost increased roots and leaves growth on seedling.  Transplanted at 30 days old seedling had the ability to grow about 95% compared to 15 days old was only 45%. It was found that female seedling was about 25% and the rest (75%) was male or sterile. It is needed further investigation on growing female seedling in the field and can it produce fruit.

Pregermination exposure of Kharkov 22 M.C. winter wheat seeds (Triticum aestivum L.) to introduced magnetic fields resulted in a stable, temperature-independent enhancement of seedling growth rate. The level of magnetic intensity required to give maximum response appears to be between 0.5 and 100 oersteds when applied for 240 hours.

Aqueous solutions of triacontanol, dihydrogen triacontyl phosphate, sodium triacontyl sulfate, sodium triacontanoate and triacontyl acetate were tested over a 10 000-fold concentration range to determine the ability of these compounds to influence the germination rate of Leeds durum wheat seeds (Triticum durum). Water, Tween-20®, octadecanol, dihydrogen octadecyl phosphate, and sodium octadecyl sulfate over the same concentration range were used as control solutions (Tween-20 is a registered tradename for the complex polymer obtained by reaction of ethylene oxide with sorbitol dehydration products). Leeds durum wheat seeds were also treated with methylene chloride solutions of octadecanol and triacontanol and grown in soil and sand. After harvesting, the fresh and dry weights of plants were determined. No enhancement of the rate of germination or growth was found in either of these studies.

The present study has been focussed on the effect of untreated tannery effluent on germination, seedling growth and pigment contents of wheat (Triticum aestivum L. var. PBW-373).Germination studies were conducted with wheat seeds having various concentrations of (4.5, 9, 13.5, and 18%) tannery effluent and five treatments (Eo, E4.5, E9, E13.5 and E18).The +ve germination parameters i.e. cumulative percent germination, germination index etc. found to be maximum in E4.5. The –ve germination parameters like delay index, percent inhibition showed minimum values for E4.5. Growth parameters also decreased with increase in effluent concentration. The pigment contents i.e. chlorophyll-a and chlorophyll-b also showed good results at E4.5.

SummarySeeds of wheat (Triticum aestivum L.) were coated with a range of vegetable oils before sowing, in an effort to provide a hydrophobic coating that would only dissolve or wash away in the presence of sufficient water to maintain continued seedling growth. Germination of oil-treated seeds was reduced by 20–50% and time to 50% emergence was increased by two to five days. Treating pesticide-coated seeds with vegetable oil further decreased germination and extended time to emergence. Oil treatment did not decrease water uptake or affect seed respiration. Degree of saturation and linoleic acid:oleic acid ratio were not correlated with the effects of the various oils. The decreased germination and delayed emergence associated with the oil treatment were probably due to physiological rather than physical factors.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.

Slow establishment of caucasian clover (Trifolium ambiguum L.) is hindering the use of this legume in pasture mixtures. Improved genetic material is one strategy of correcting the problem. Newly harvested seed of hexaploid caucasian clover germplasm covering a range of origins, together with white and red clover and lucerne, were sown in 1 m rows in a Wakanui soil at Lincoln in November 1995. After 21 days, the caucasian clover material as a group had similar numbers of emerged seedlings as white clover and lucerne, but was inferior to red clover. There was wide variation among caucasian clover lines (48-70% seedling emergence), with the cool-season selection from cv. Monaro ranked the highest. Recurrent selection at low temperatures could be used to select material with improved rates of seedling emergence. Red clover and lucerne seedlings produced significantly greater shoot and root dry weight than caucasian and white clover seedlings. Initially, caucasian clover seedlings partitioned 1:1 shoot to root dry weight compared with 3:1 for white clover. After 2 months, caucasian clover seedlings had similar shoot growth but 3 times the root growth of white clover. Between 2 and 5 months, caucasian clover partitioned more to root and rhizome growth, resulting in a 0.3:1 shoot:root ratio compared with 2:1 for white clover. Both clover species had similar total dry weight after 5 months. Unhindered root/ rhizome devel-opment is very important to hasten the establishment phase of caucasian clover. The caucasian clover lines KZ3 and cool-season, both selections from Monaro, developed seedlings with greater shoot and root growth than cv. Monaro. KZ3 continued to produce greater root growth after 5 months, indicating the genetic potential for improvement in seedling growth rate. Different pasture estab-lishment techniques are proposed that take account of the seedling growth characteristics of caucasian clover.
