The cono weeder was procured evaluated for its field performance for long duration in paddy crop (Sona masuri) at farmer's field. The average row spacing, hill to hill spacing and height of crop were found to be 30cm, 10cm and 38cm, respectively. The average plant population of crop in square meter area was 32. The type of weed observed was Cypruss rotendus and Cynodan dectylan. The average height and population of weed in square meter area were 10cm and 125cm, respectively. The results indicated that, the field capacity was in the range of 0.016 to 0.019 ha/h with a field efficiency in the range of 59.23 to 62.07 per cent. The per cent weeding efficiency was observed in the range of 72.00 to 85.0. The average effort required to push the cono weeder was 14.4kgf. The Brinell hardness number of the weeding cone was observed in the range of 159 to 187. The per cent wear on dimensional basis in the right and left weeding cones was observed 4.75 and 3.80, respectively.Keywords

An experiment was conducted to study the performance of cattle dung at different total solids (TS) viz., 10, 12, 15 and 18 per cent in three in prototype digesters of 1:0.5, 1:1 and 1:1.7 (H/D ratio) size for a retention period of 56 days under laboratory conditions. The results indicated that, at 10% TS, the cumulative gas production was maximum (345.8 litres) in 1:1.7 H/D size digester followed by 1:1 size digester (305.2 litres) and 1:0.5 size digester (255.8 litres) at the end of retention period of 56 days. While the maximum cumulative gas production of 393.9 litres was recorded in 1:1.7 H/D size digester followed by 1:1 size digester (358.1 litres) and 1:0.5 size digester (297.0 litres) at the end of retention period of 56 days at 12% TS . Whereas at 15 % TS, the maximum cumulative gas production of 474.5 litres was recorded in 1:1.7 H/D size digester followed by 1:1 size digester (419.3 litres) and 1:0.5 size digester (348.4 litres) at the end of retention period of 56 days. It was observed that the cumulative gas production was maximum in 1:1.7 H/D size digesters followed by 1:1 H/D size digester and 1:0.5 H/D size digester at all the total solids fed. The average percentage of methane content was maximum (57.09 %) in the gas produced from cattle dung at 15 per cent TS in 1:1.7 size (H/D ratio) digester, whereas a minimum of 52.48 percentage of methane content was recorded in the gas produced from cattle dung at 10 per cent TS in 1:0.5 size (H/D ratio) digester.Keywords
