This investigation was carried out at Hada AL-Sham Agricultural Research Station, KAU to study the behavior of three sugar beet cultivars (Farida, Dita and Heros) under three intercropping systems (sugar beet sole, 1sugar beet: 2 clover and 1sugar beet:3 clover rows) during 2016-208 seasons. Intercropping systems produced higher root and sucrose yield/ha more than sole plantation. In addition, Farida cv was the highest in root and sucrose yield compared with the other cultivars. Farida cv under the1sugar beet: 3clover intercropping system produced the highest sucrose yield/ha (4.45t and 7.04 t/ha in the 1st and 2nd seasons, respectively).

The growth to slaughter and carcase characteristics of purebred and crossbred lambs from five ewe breeds were compared in an experiment in 1971 and 1972 at Temora Agricultural Research Station. The ewe breeds were a Border Leicester x Merino fixed halfbred (BLM), Corriedale, Polwarth, a South Australian strong wool (SA Merino) and a medium wool Peppin strain of Merino. In each year, ewes of each breed were joined either to their own breed of ram or to Dorset Horn rams. The analysis used tested whether differences between ewe breeds in crossbred performance were halved compared with the differences between ewe breeds in purebred performances. The results supported this hypothesis for all characters measured. The largest breed effects on lamb performance were found for growth rate. Compared with the overall mean, the growth rates to weaning for purebred lambs were 118%,102%, 90%, 99% and 91% 10 for the BLM, Corriedale, Polwarth, SA Merino and Peppin Merino, respectively. The deviations from 100% for crossbred lambs were halved. Differences between breeds for carcase traits were estimated at the same carcase weight. South Australian Merino lambs had a lower dressing percentage than lambs from .the other breeds. Polwarths had the greatest depth of fat at the 12- 13th rib. Skins from Merino lambs had shorter staples and higher visual counts than skins from the other breeds. However, it was concluded that breed differences in carcase and skin characters, independent of carcase weight, were of little value in an economic comparison of the breeds for total productivity.

This experiment was conducted in Homs Agricultural Research Station, Homs, Syria during 2007/2008 and 2008/2009 seasons to study the effect of sowing date and plant density on bolting for four sugar beet varieties, tow are monogerm varieties i.e. Parade and Etna, while the other are multigerm varieties i.e. Nadir and Mammoth. Three sowing dates were applied, began from 15/9 to 15/10, the interval between the sowing dates was 15 days. Three plant densities were executed (133 000, 100 000 and 80 000 plantha-1). Split plot design was used with three replicates. The combined analysis exhibited the significant effect of varieties (V), sowing dates (S), and plant densities (D) on all types of bolting (Early, medium, late and total). Least significant test (L.S.D 0.05) clarified that early autumn sowing (15/9 and 1/10) increased total bolting percent 74.86 and 44.88 % respectively, as compared with date (15/10) 15.57% (control). The plant density (133 000 plant ha-1) decreased total bolting percent 43.56% as compared with the other plant densities (80 000 and 100 000 plant ha-1) 46.35 and 45.40% respectively. The results showed that the monogerm varieties were superior and more resistant to bolting as compared with the multigerm ones.

The initial growth of turmeric is rather slow and takes about 4-5 months to cover the inter space. Therefore, the available space between the rows of turmeric could be effectively utilized by growing short duration crops like, vegetables, cereals etc. Hence, it is worthwhile to explore the possibilities of growing compatible crops with turmeric. With this background the experiment on effect of intercrops on growth and yield of turmeric was conducted at Agricultural Research Station, Bhavanisagar. Among the different intercrops, turmeric with cowpea recorded the maximum fresh rhizome yield per hectare (30.78 t ha-1) while turmeric + bhendi registered the maximum B:C ratio (2.68:1). Monocropping of turmeric recorded the lowest B:C ratio (1.67:1) among all the treatments.

A field experiment was conducted during kharif, 2005 at Agricultural Research station, Devihosur, Haveri, Karnataka to assess the progress of powdery mildew at different time interval of sowing dates. Totally 20 different dates of sowings were imposed in the experiment at an interval of 10 days. The crop sown on last week of May to mid of June recorded minimum disease severity compared to rest of the date of sowings. This clearly indicated that crop sown during this period suffers less, which may be due to low inoculum potential, whereas late sown crop suffers more because of the readily available inoculum in the early sown crops. Low disease severity in last week of May to mid of June sowing may be attributed to the non-congenial weather factors for the development of the disease.

Field experiments were conducted from 2015-16 to 2017-18 on a Typic Rhodustalfs (Alfisol) soils of Telangana at Regional Agricultural Research Station, Palem, Nagarkurnool, Southern Telangana Zone, India to validate targeted yield based fertilizer prescription equations which developed for hybrid castor by adopting eight treatments viz., Blanket recommendation (100% RDF:80:40:30 kg N, P2O5 and K2O ha-1), Blanket+5 t ha-1 of vermin-compost (VC), STCR-Target yield with NPK alone at 25q ha-1, STCR-Target yield with IPNS at 25q ha-1, STCR-Target yield with NPK alone at 30q ha-1, STCR-Target yield with IPNS at 30q ha-1, Farmer’s practice (40:20:0kg N, P2O5 and K2O ha-1) and Absolute control (without inorganic and organic fertilizers). The findings of these test verification trials clearly revealed that the percent achievement of the aimed yield target was within + 10 percent variation confirming the validity of the equations. Using STCR-NPK@25 and 30q ha-1 recorded significantly higher seed (20.74 and 22.30q ha-1) and stalk (24.63 and 26.36q ha-1) yield over blanket recommendation (19.40 and 23.13 q ha-1), while STCR-IPNS at 25 and 30 q ha-1recorde relatively higher seed (20.98 and 22.69q ha-1) and stalk (25.88 and 27.13q ha-1) yield over STCR-NPK alone treatments. The magnitude of built-up was higher with STCR-IPNS treatments as compared to STCR-NPK alone, blanket recommendations, farmer’s practice and absolute control.

Deferred grazing is the practice of holding over pasture in situ that has been considered surplus to animal requirements in spring, to be grazed at a later date when a shortage of pasture occurs, usually in summer/autumn. This non-mechanical method of pasture conservation was developedandpractised from 1986-1989 at the Taranaki Agricultural Research Station as part of a low cost dairy system. At the low stocking rate (3.7 cows/ha) 13% of the farm area was conserved as deferred grazing and allowed to naturally reseed before grazing. The reseeding doubled the tiller density of perennial ryegrass, increasing pasture growth by 15 19% the following season. This, combined with the nil cost associated with conserving supplements, made this system more profitable than the traditional haysilage system. For the natural reseeding to be successful, the deferred grazed pasture should be removed from thegrazingrotationduringtheryegrassreproductive phase (mid-October to mid-November) and not grazed until after the ryegrass seed is mature (mid- January). The method developed to Wise deferred grazed pasture has been to strip graze between the morning and night milkings. Cows are offered a pasture allowance of 10 kg DM/cow/day or one, two hundred and fiftieth of the farm per day, to achieve a utilisation of around 50%. Cows graze selectively leavingaresidualofabout4000kg DM/ haofpredominantly dead material. Mowing before grazing increased utilisation, but there was no advantage in milk solids production. No benefits were observed when tall fescue or phalaris pastures were allowed to naturally reseed. Deferred grazing had no effect on grass grub or porina populations if grazed before April. No detrimental animal health effects have been measured with deferred grazing. To reduce farm operating costs and increase pasture growth, it is recommended that 10% of the farm is deferred and allowed to naturally reseed on an annual basis.
