Agriculture is the second largest contributor (20%) to total anthropogenic greenhouse gas (GHG) emissions in world. There a need identify energy and carbon efficient cropping systems that reduce GHG emission improve environmental quality. Using life cycle assessment (LCA), we evaluated four namely fallow – chickpea (F–C); Sesbania mustard (Ses–M); blackgram (B–C); sorghum + cowpea (S+C–M) cultivated during 2018-2022 period. The use pattern input-output relationship were analysed. Three...
Tillage is an important agricultural operation which influences soil properties, crop yield and environment. Nine combinations of three tillage practices including conventional (CT), minimum (MT) zero (ZT) were evaluated in fodder sorghum (Sorghum bicolor) + cowpea (Vigna unguiculata) – wheat (Triticum durum) cropping system for 5 years (2009–2014) on clay loam under limited irrigation. Continuous ZT significantly improved surface organic carbon, bulk density, infiltration rate maximum water...
The field experiment was conducted during the kharif and rabi seasons of 2020 2021 at ICAR-Central Institute for Research on Goats, Makhdoom, Mathura, Uttar Pradesh to optimize year-round fodder production 20 goats their 30 followers using one acre land through development intercropping concept with different cereals leguminous crops; along implementation good agricultural practices (GAP) rainy (kharif) winter (rabi) seasons. technique demonstrated potential yield 7,600 kg green 760 maize...
The perennial grass-legume cropping system benefits soil because of its high biomass turnover, cover nature, and different foraging behaviors. We investigated the response organic carbon (SOC) pools their stock to inorganic nutrient management in Guinea grass legume (cowpea-Egyptian clover) system.Depth-wise samples were collected after harvesting Egyptian clover. Based on ease oxidation with chromic acid, SOC oxidizable using Walkley-Black C method, very labile, less non-labile; dissolved...
Traditional way of rice transplanting is labor intensive and involves drudgery. Mechanical transplanter costeffective operation friendly. It helps in maintaining soil physical properties considered to be better from crop management productivity point view. In spite having an edge over the traditional transplanting, adoption rate mechanical transplanters low due high initial investment lack knowledge growing mat type nursery. Imparting technical knowledge, ensuring timely availability...
Engine performance and emission characteristics of unmodified biodiesel fueled diesel engines are highly influenced by their ignition combustion behavior. In this study, were studied when the engine operated using different blends (B10, B20, B30, B40) normal fuel (B0) as well varying compression ratio from 16.5 : 1 to 17.5 18.5 1. The change resulted in 27.1%, 27.29%, 26.38%, 28.48%, 34.68% increase cylinder pressure for B0, B10, B40, respectively, at 75% rated load conditions. Higher peak...
Bezoars are collections of non-digestible matter that usually accumulates in stomach and can extend to small bowel. Trichobezoars (concretions hair) unusual found young psychiatric females, who often deny eating their own hair (trichophagy). We presenting a case gastric trichobezoar with long thin tail 20 years female history trichophagia. Patient was managed by exploratory laparotomy anterior gastrotomy. Postoperatively she recovered well discharged satisfactory condition advice for follow-up.
Variable-rate technology (VRT) may reduce input costs, increase crop productivity and quality, help to protect the environment. The present study was conducted evaluate performance of a variable-rate fertilizer applicator for rice (Oryza sativa L.). Three replications were conducted, each which divided into four plots. Field system assessed at different nitrogen levels (N1 N4, i.e., 75, 125, 175, 225 kg ha−1), growth stages (tillering, panicle initiation, heading), heights (40, 60, 80, 100...
Soil organic carbon (SOC) is a key component for sustaining crop production. A field experiment was conducted during 2004–2018 to assess the changes in soil fractions under different fertilization practices grass-legumes mixture. The result indicates that application of farmyard manure (FYM) at 80 Mg ha–1 has increased SOC concentration leading sequestration rate 4.2 year–1. Further, it proportion labile total and have accumulated 126, 60, 83 95% higher very labile, less non-labile C stock...
Abstract In winter, the paddy residues become wet during morning and late evening due to dew, which restricts operation of sowing machines (Happy Seeder Super Seeder) into residues, as do not slide on furrow openers/tines. A PAU Smart (PSS) was developed evaluated for a four-wheel tractor that can sow wheat with optimum crop establishment in combined harvested rice fields. The PSS were its performance under varying straw load, forward speed, rotor speed terms fuel consumption, field...
Maize (Zea mays L) is one of the most versatile emerging cereal crops having wider adaptability under varied agro-climatic conditions. Pre and post harvesting operations are labour intensive that presently done manually in India need to be mechanized. The physical properties seeds play an important role for designing seed metering device. Three varieties maize PMH-1, PMH-10 PIONEER-3396 were evaluated their engineering laboratory. Therefore, such as size, shape, hundred grain weight, angle...
Paddy straw management in combine harvested paddy fields is a major problem paddy-wheat rotation. A study was conducted to evaluate the performance of tractor operated mulcher field. Effective field capacity 0.32 ha/h at forward speed 2.64 km/h. Average fuel consumption for machine 5.88 l/h. The percent chopped size by up 10 cm 83.44%. No or very little accumulation observed operation spatial no till drill direct drilling wheat after mulcher. grain yield treatment T1 (Paddy + sowing with...
Abstract To reduce the human effort involved in walk‐behind paddy transplanter operation, a remote‐control system consisting of an electronic control unit (ECU) was designed and developed. A separate remote handheld wireless kit developed to ECU. The deviation from straight‐line path measured by mounting real‐time kinematic global satellite navigation on provide plot transplanter. results field evaluation revealed that worked properly with effective capacity 0.16 ± 0.03 ha h −1 efficiency...
Onion (Allium cepa L.) is one of the major vegetable crops grown throughout India.Pelletizing onion seed by providing a coat helps in changing physical characteristics seed.Experiment was conducted for studying properties pelleted and these were compared to un-pelleted seed.The variety Punjab Naroya (PN) used experiment.The namely size, shape, thousand grain weight, angle repose, bulk density coefficient static friction are important from engineering view point.The seeds got pelletized three...
