A field experiment was conducted to evaluate the efficacy of ametoctradin 300 g/l + Dimethomorph 225 g/l sc against downy mildew disease of grapes for 2 seasons at Agricultural Research Station Bagalkot district. It was found that Ametoctradin 300 g/ l + Dimethomorph 225 g/l sc is highly effective in reducing the downy mildew disease in grapes. Further the phytotoxicity was not observed in the chemical Ametoctradin 300 g/l + Dimethomorph 225 g/l sc to the treated plots of grapevine even at high doses and also exhibiting an appreciable increase in grape berry yield.

Sowing Dates

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.

A field experiment was conducted at Agricultural Research Station, Malnoor, University of Agricultural Sciences, Raichur on vertisols during kharif seasons of 2010-11 and 2011-12 to study the productive potential of pigeonpea genotypes in different planting geometry under protective irrigation. The experiment consisted of three genotypes (BSMR-736, TS-3R and Laksmi) and seven planting geometry ( 90 x 20 cm, 120 x20 cm, 120 x 60 cm, 120 x 90 cm, 150 x 20 cm, 150 x 60 cm and 150 x 90 cm). The experiment was conducted in split plot design with three replications. Results revealed that among three genotypes tested, BSMR-736 (1667 kg/ha) recorded significantly higher grain yield over Laksmi (1369 kg/ha) and TS-3R (823 kg/ha). With respect to planting geometry, 90 x 20 cm, 120x20 cm and 150x20 cm recorded the highest grain yield, net returns and B:C irrespective of the genotypes. The interaction between genotypes and planting geometry showed that the genotype BSMR-736 planted at 150X20 cm recorded the highest grain yield (2322 kg/ha), net returns (Rs. 64421/ha) and B:C (4.37).

A field experiment was conducted to study the influence of spacing on clusterbean varieties in alfisols of scarce rainfall zone under rainfed situation for consecutive three kharif seasons of 2013, 2014 and 2015 at the Agricultural Research Station, Ananthapuram of Andhra Pradesh. Pooled data revealed that higher yield was recorded with branched varieties (447 kg ha-1) than unbranched varieties (445 kg ha-1). Unbranched variety produced higher haulm yield. Among crop geometry, 22.5 x 10 cm recorded higher seed yield of 512 kg ha-1 while lowest seed yield of 393 kg ha-1 obtained with 45x10 cm. Among crop geometry tested, higher haulm yield was registered with 45x7.5 and 22.5x7.5 cm spacing resulted lowest haulm yield. Considering the economics and large scale availability of seed drills and planters with farmers sowing of cluster bean either branched or unbranched genotypes with 30 x 7.5 or 10 cm spacing was found optimum.

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.

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.

An experiment was conducted at the Hill Agricultural Research Station, Khagrachari from September 2002 to February 2003 to find out the effect of mulching method (Mulching one month before planting, mulching just after planting and no mulching) and planting times (01 October, 16 October and 01 November) on the yield and yield attributes of tomato in hill slope. The highest yield (21.43 t/ha) was obtained from plant where mulch was given one month before planting. Among three planting times, the highest yield (15.27 t/ha) was obtained from 01 October planting. In case of combined effect, mulching one month before planting with 01 October planting produced the highest yield (28.06 t/ha) of tomato in hill slope. Key Words: Mulching; planting time; tomato yield; hill slope.  DOI: 10.3329/bjar.v34i2.5793Bangladesh J. Agril. Res. 34(2): 227-232, June 2009

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.
