    Design, development and evaluation of baling attachment with self propelled combine harvester
    (Punjab Agricultural University, Ludhiana, 2022) Ajaib Singh; Singh, Shashi Kumar
    Paddy straw burning is the major issue of Punjab and its adjoining states. The problem of paddy residue burning can be reduced if the loose paddy residue coming out from the conventional combine harvester is managed successfully. A baling attachment with the self propelled combine harvester was designed and developed. Performance of the baling attachment with the combine harvester was evaluated at two levels of forward speed (F1 = 2.0 and F2 = 2.5 km h-1), three levels of belt conveyor speed (B1 = 1.15, B2 = 1.40 and B3 = 1.50 m s-1) in two paddy varieties (V1 = PR 126 and V2 = PR 122). The best operational parameters on the basis of less straw walker and sieve loss were F1B1, F1B2 and F1B3 and on the basis of less fuel consumption (l ha-1) and higher field capacity, the better operational parameters were F2B1, F2B2 and F2B3. The samples of untreated paddy straw, urea fermented baled and stacked paddy straw were analyzed for proximate principles (dry matter, total ash and crude protein) and cell wall constituents (acid detergent fibre, neutral detergent fibre and acid detergent lignin). All the parameters of the proximate principles and cell wall constituents of urea treated paddy straw (both in stack and bale form) were significantly different from the untreated paddy straw. The total income from the fermented bales formed by the baling attachment with self propelled combine harvester and bales from the conventional baling system came out to be Rs. 10046.00 ha-1 and Rs. 13065.10 ha-1, respectively.
