Wood sample taken from the trunk of 3 year old Leucaena leucoceaphala tree was found to have a medium density and EMC and a higher heating value. Its cellulose and carbon contents were high and the ash content was low. Similar sample taken from Sesbania grandiflora plant had a low density and FMC. Compared to Leucaena leucocephala wood, it had lower heating value, less cellulose, more lignin, a lower carbon content Ind higher ash and silica contents. On the basis of the physical and chemical charaeleristics, Leucaena leucocephala wood is considered to be a superior fuel wood and a better raw material for gasification and pyrolysis.- Study of Surface Profile of Rotary Blades

Wear of soil engaging components occurs because the materials used are normally softer than the natural abrasives in the soil. Most of blades of rotavator are manufactured locally which are hardly at par with the standards in terms of material, shape and size which affects operational life of rotary tool. So, there was a need to study wear characteristics of rotary blades so as to provide the proper blades in the rotary tools. Study was conducted in rotary soil bin in loamy soil and sandy loam soil. L-Shape blade of four different makes was mounted on the two flanges and their speed varied from 140-150 rpm. Two rollers along their stand were mounted on soil bin for compressing the soil upto 4.5 - 5.0 kg/cm2 compaction. The width of rotary blades was measured before and after the wear test. The profile change of rotary blades can also be used to determine the wear characteristics of tillage tools. The decrease in width of blade T1,T2, T3 and T4 at starting point of blade section were 10.65%, 13.95%, 3.68% and 4.36 %, respectively in loam soil while the decrease in width of blade T1,T2,T3 and T4 at starting point of blade section were 15.10%, 17.10%, 13.50% and 18.65 %, respectively in sandy loam soil.Keywords

Artificial ground water recharge is an effective way to counter the adverse effects of declining water table of Punjab. Most of the rainfall was received during the months of July, August and September in Hoshiarpur district during 2011-2013. The average rainfall received for year 2011-2013 is 768.6 mm. The maximum rainfall of 236.6 mm (28.7%) was received in the month of August and the minimum rainfall of 3.1 mm (0.4%) was received in the month of November. Excessive rainfall in the district causes excessive runoff and sediment loss due to undulating terrains. Rooftop rainwater harvesting during rainy season holds good potential for recharging the depleting groundwater aquifiers. A rooftop rainwater harvesting structure having siltation unit (1.5 m x 0.75m x 1.5m), filtration unit (1.5x 0.30m x 0.9m) and storage tank(1.5 m x0.45m x 0.9 m) was constructed and evaluated at Krishi Vigyan Kendra, Hoshiarpur. This structure contributed an average of 2.04 lakh litres groundwater recharge. The study revealed that there was a need to adopt this technique at mass level to get significant results. This would be possible only with the help of people participation.Keywords

Evaluation of different wheat sowing technologies under paddy residue conditions were conducted in a combine harvested paddy field. Field of paddy variety PR-121 was harvested with combine. The straw load was 8.22 t/ha at moisture content of 20.2 per cent. Wheat variety (HD 2967) was sown with different farm machines viz., T1: Happy seeder, T2: Spatially modified no till drill and T3: Roto till drill in combine harvested paddy fields. In T1, all the paddy straw was remained in the field itself but spreaded uniformly manually/stubble shaver, in T2, 40 per cent of loose paddy straw removed manually/chopping of paddy straw with paddy straw chopper cum spreader while in T3, there was a partial collection of loose paddy straw manually for better operation of the machines. The grain yield was maximum in treatment T2 (5395.9 kg/ha).Keywords

This study was conducted to evaluate the performance of maize combines having different types of headers i.e. snap roll type header and cutter bar type header. The mean forward speed and mean field capacity for cutter bar type header type header was 2.10 km/hr and 0.30-0.40 ha/hr, respectively while mean forward speed and mean field capacity for snap roll type header was 1.50 km/hr and 0.20-0.30 ha/hr, respectively. Shattering loss in snap roll type header combine was 12.50 to 18.50 per cent while shattering loss in case of cutter bar type header was 5.00 to 10.50 per cent.Keywords

The present study assessed the energy requirement for the harvesting of paddy with combine harvesting with/without Super Straw Management System and wheat sowing with different farm machinery having straw retention and straw incorporated in the fields. The straw retention treatments i.e. T1and T2 whereas straw incorporation treatments i.e. T3 and T4 were taken in the study. The total energy consumption was maximum for treatment T4 (5529.92 MJ/ha), followed by treatment T3 (5487.47 MJ/ha), followed by treatment T2 (3485.15 MJ/ha) and treatment T1 (2539.40 MJ/ha). The least human energy consumption (22.01 MJ/ha), diesel energy (551.95 MJ/ha) and tractor and machinery energy (551.95 MJ/ha) was observed for treatment T1, while the maximum human energy, diesel energy, and tractor and machinery energy was observed in treatment T4 (52.17 MJ/ha), T3 (3442.63 and T4 (644.89 MJ/ha). The electrical energy (1401.78 MJ/ha) and submersible pump energy (13.68 MJ/ha) was observed in treatment T3 and T4, respectively. The residue retention practice of wheat sowing with Happy Seeder after paddy harvesting with combine harvester having Super Straw Management System is the efficient energy input to manage the paddy residue.Keywords
