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.

Nitrogen (N) is the most critical plant nutrient. Maize has a high nitrogen demand. Low maize (Zea mays L.), yields in smallholder farms of Malawi, the country’s staple, is attributable to declining N fertility aggravated by the ever increasing price of fertilizer. Little effort has been made to establish the best nitrogen rate in a maize- cowpea and maize-bean intercrop under variable soil conditions as a way of improving production, and was the objective of the current study. Field experiments were conducted at Chitedze Agricultural Research Station in Lilongwe and Makoka Agricultural Research Station in Zomba during the 2016/17 growing season. A split plot layout in a randomized complete block design, with three replicates was used. The main plots were; sole maize, sole bean, sole cowpea, bean/maize and cowpea/maize intercrop systems. The sub plots were N fertilizer rates (0, 52.5, 78.75 and 105 kg N ha-1), applied as urea. The data collected was subjected to analysis of variance using SAS software version 9.3 (SAS Institute Inc.) at P<0.05. Means were separated using Duncan Multiple Range (DMRT) test at 95% significance level. The results showed that application of N increased maize N uptake and grain yield. NUE however decreased with increasing N fertilizer rate.

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.

A relevant improvement of the cultivar conditions of Rosmarinus officinalis L. in desert areas was achieved by a specific combination between irrigation system and soil conditioner. A drastic reduction of water employment was obtained without affect the quality of the plants, determined by monitoring growth parameters and essential oil characteristics. In particular, the effect of surface and subsurface drip irrigation systems and different soil conditioners on growth parameters, yield, and essential oil constituents of rosemary plant was assessed. Field experiments at the Agricultural Research Station (Al-Adlya farm), SEKEM group Company, El-Sharkiya Governorate, Egypt, conducted over the two seasons revealed the effectiveness of the subsurface irrigation system in obtaining better performances, especially in terms of water saving. The combination of subsurface irrigation and the conditioner Hundz soil with bentonite showed the maximum mean values of growth characters compared with other soil amendments during both seasons. The possibility to employ a water-saving irrigation system as the subsurface one without any drawback in the resulting plants was also explored in terms of molecular composition. GC-MS analysis of the essential oil extracted from plants growth under different irrigation conditions revealed a comparable composition in both cases. The goodness of the most performing system was also confirmed by the comparable yield of the essential oil.

A field experiment was conducted at Agricultural Research Station, Baljigapade, Chikkaballapur taluk and district, which comes under the Eastern Dry Zone of Karnataka during Kharif season 2018. The experimental plot in the field was laid out following a randomized complete block design (RCBD) with fourteen treatments and three replications. The treatments included two levels of N and P2O5 (20 and 30 kg ha-1) and three levels of K2O (10,20 and 30 kg ha-1). Farmyard manure was applied at the rate of 6.25 t ha-1 to all the treatments except absolute control. Results indicated that application of 30 kg N+30 kg P2O5+30 kg K2O ha-1 with Farm Yard Manure (FYM) increased the micronutrient availability in soil N (150.29 kg ha-1), P2O5 (17.60 kg ha-1), K2O (160.84 kg ha-1). Application of FYM @ 6.25 t ha-1+30 kg N+20 kg P2O5 +20 kg K2O ha-1 significantly increased growth, yield, macronutrient content and uptake by brown top millet grain and straw against absolute control. The grain yield of browntop millet was increased by 61.46 percent in T10 and 59.07 percent in T9 as compared to the 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.
