In order to study the effect of organic fertilizer on shoot yield and essential oil content of lavender, this experiment was conducted in the Research Institute of Forest and Rangelands, Karaj, Iran, in 2013-14. The treatment groups consisted of vermicompost (0, 5, 10 and 15 ton/ha) and cow manure (0, 10, 20 and 30 ton/ha). The experimental design was a factorial experiment based on randomized ...

Background: The cluster bean [Cyamopsis tetragonoloba (L.) Taub.] is a bushy annual herb having deep rooted system and drought resilient leguminous crop grown on sandy soils of arid semiarid regions. production list dominated by India as leading producers the in world contributing to around 75-82% total production. Methods: Field experiment was conducted Block-I at Regional Horticulture Researc...

The gap between actual and potential crop production can be minimized by maintaining plant health, which needs crop-specific technology interventions. On-farm trials were conducted during 2017-18 2018-19 in the farmers’ fields Sundarbans to study impact of technologies on yields. yield mustard increased about 47% with installation A. mellifera bee hives @ 3 ha-1 while it was 40% case cerena typ...

The role of the hematopoietic lineage-restricted minor histocompatibility (H) antigen HA-1 in renal allograft tolerance was explored. We obtained peripheral blood samples from three recipients of histocompatibility leukocyte antigen (HLA)-matched, HA-1-mismatched renal transplants, one of which had discontinued immunosuppression >30 yr ago while sustaining normal kidney function. Peripheral blo...

A field experiment was conducted for two years during 2019 - 21 at Field No.36 of Eastern block farm, Department Agronomy, Tamil Nadu Agricultural University, Coimbatore to identify the suitable plant spacing and nutrient levels getting higher fodder yield economics in maize pre-release culture TNFM 131-9. The laid out split plot design with three replications. treatments consisted four viz., 3...

Although commercial formulations of Bacillus thuringiensis subsp. kurstaki (Btk) are being widely used in forest protection against lepidopteran defoliators, optimal application prescriptions have often yet to be worked out in detail. We conducted field experiments over a 6-yr period (1996-2001) in southwestern Québec to determine application prescriptions for optimal protection of balsam fir, ...

The study was carried out for two consecutive years (2005-06 to 2006-07) to evaluate the wheat response to five different levels (0, 4, 8, 12 and 16 kg ha) of manganese (Mn) alongwith 150-100-60 kg NPK ha application. The experiment was laid out in randomized complete block design (RCBD) with three repeats under irrigated conditions at Agriculture Research Farm Karor, District Layyah. NPK was a...
