Integrated nutrient management (INM) under reduced tillage practices improve soil properties and plant nitrogen (N) dynamics. The effects of urea, farmyard manure (FYM) and soybean residue (SR) under different tillage systems were evaluated in 2-year field experiments for N translocation and translocation efficiencies. Tillage systems included minimum (MT), conventional (CT) and deep (DT) tilla...

The field experiment entitled “Influence of Biofertilizers and Nitrogen on the Growth Yield Barley (Hordeum vulgare L.)" was conducted during Rabi season, 2022 at Crop Research Farm in Department agronomy, Naini Agriculture Institute, Sam Higginbottom University Agriculture, Technology Sciences, Prayagraj Uttar Pradesh. study included biofertilizers three levels (60, 80 100 kg/ha) control. layo...

A study was conducted to determine the effects of solid‐liquid separation of liquid swine manure on ammonia emissions from lagoons. This determination was done at full‐scale in two contiguous swine production units that had similar animal production management. One of these units was maintained as a control using the anaerobic lagoon treatment method. In the second production unit, solids were ...

Regaining the agricultural potential of sodic soils in the Indo-Gangetic plains necessitates the development of suitable salt tolerant rice varieties to provide an entry for other affordable agronomic and soil manipulation measures. Thus selection of high yielding rice varieties across a range of sodic soils is central. Evaluation of breeding lines through on-station and on-farm farmers' partic...

A field experiment was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during kharif¸ 2015 on loamy sand soil. The comprising four levels sulphur (0, 20, 40 and 60 kg/ha) sesame varieties (RT-125, RT-127, RT-346 RT-351) thereby making 16 treatment combinations laid out in randomized block design replicated thrice. Results revealed that N, P S concentration seed sta...

The low average grain yield (0.7 ton ha(-1)) of tef in Ethiopia is mainly attributed to low soil fertility, and inappropriate tillage and weeds control practices. Despite this, limited scientific information has been documented so far on their interaction effects on tef crop productivity in northern Ethiopia. The objective of this study was to assess the separate and interaction effects of till...

Long-term water quality records for assessing natural variability, impact of management, and that guide regulatory processes to safeguard water resources are rare for California oak woodland rangelands. This study presents a 20-yr record (1981-2000) of nitrate-nitrogen (NO(3)-N) and suspended sediment export from a typical, grazed oak woodland watershed (103 ha) in the northern Sierra Nevada fo...

Field experiment were conducted at CSK HPKV Research Farm, Palampur during Rabi seasons of 2000-01 and 2001-02, to study the response of onion (Allium cepa var Patna red) at four sulphur levels (0, 15, 30 and 60 kg ha(-1)) applied through Gypsum and S95. The analysis was done to allocate the limited availability of sulphur for maximizing net profit over fertilizer cost. The results show that th...

Wheat (Triticum aestivum L.) is widely cultivated in the Mediterranean zone where plantsgenerally suffer from water stress during heading and reproductive stages. This research wascarried out at the experimental farm of the faculty of agriculture, Kafrelsheikh University usingtwo water treatments (water stress and well-watered), four N levels (0, 80, 160 and 240 kg ha-1)and two ascorbic acid le...
