An efficient design of conservation tillage trencher (CTT) saves time, natural resources, and conserves soil health by avoiding vigorous soil disturbance of tillage operations. A two-wheel tractor operated CTT has constructed with modified rotary shafts, toolbar frames, depth control bars, bed shapers and chisel ploughs for conservation tillage operation of sugarcane plantation. The performance evaluation of developed CTT was tested for comparing the suitability with small-scale farmer’s practice (SFP) and large farm practice (LFP). Finally, the CTT is applied for preparing sugarcane farmland in different conservation tillage methods of i) bed cum trenching (BT), ii) zero-tillage trenching (ZT) and iii) strip-tillage (ST). The performance of effective field capacities of CTT were 0.14 ha h-1, 0.12 ha h-1 and 0.14 ha h-1 for BT, ZT and ST, respectively. Developed CTT saved time 80% and 26-37% over SFP and LFP, and required 96% and 26-36% less labour than SFP and LFP, respectively. Conservation tillage required 7-10 l ha-1diesel whereas SFP and LFP required 25 l ha-1and 65 l ha-1, which reduced CO2 emission by 60-72% and 85-89% compared to SFP and LFP, respectively. Ultimately, newly developed CTT saved sugarcane land preparation costs by 86% to 90% compared to conventional tillage systems.

A small-scale maize harvester was designed and fabricated for developing countries and is composed of a harvester header, a chain conveyor, a drive power unit and a five-wheel tricycle. Fabrication of components was made and assembling of the devices on the tricycle was done. The performance evaluation of the small-scale maize harvester was done at 15% kernels moisture content (wet basis). Three rotational speeds of the engine, 1347, 1521 and 1937 rpm were used, while the forward velocity of the harvester was kept at an average of 0.617 km.hr-1. The testing experiment revealed significant effect of physical properties of maize (p<0,05). The highest machine capacity was obtained at 0.05 ha.hr-1, while the highest driving efficiency was 97.30% and the highest picking and conveying efficiencies were 84.11% and 98.21%, respectively. However, it was observed that the machine noise level decreased with increase in engine speed. Also, the engine speed affected both picking and conveying efficiencies. The designed machine is found suitable for most smallholder farms.

The climate of the terai region of West Bengal, India in general, is subtropical par humid to tropical with light textured acid soil with the problems like low moisture retention, low water use efficiency, leaching of bases, soil erosion, limited availability of multiple plant nutrients and restricted activity of beneficial soil micro-organisms. To combat these soil health related problems and to improve the overall productivity of North Bengal, a comparison between the conventional and conservation tillage was taken up and the immediate results were measured in terms of growth, yield attributes and yield. In the first two years of experimentation, though different growth attributes, grain yield, stover yield, and different yield attributing characters such as kernel rows cob-1, number of kernels row-1, 100 seed weight (g), number of seeds cob-1, girth of cob, length of cob and number of effective cob plant-1 were higher in conventional tillage as compared to conservation tillage but in terms of soil heath characteristics, conservation tillage had a meaningful remark from the initial years towards the future food security. Mulching @ 4 t ha-1 was found to have performed better than unmulched treatments. Application of 75% recommended dose of fertilizer + Vermicompost @ 10 t ha-1 resulted in better growth and yield attributes which directly influenced to have higher grain and stover yield.

Potato Peeling

An Irish potato peeling machine was developed for use at small-scale/household level. Machine performance evaluation was carried out using three locally grown Irish potato varieties namely; Nicola, Bartita and Bawondoya respectively. A 22x3 factorial experiment in completely randomized design (CRD) with three replications was used for evaluation where tuber feed rate, shaft speed and variety were the independent variables and peeling efficiency, tuber flesh loss and machine output capacity were the performance indicators. Analysis of variance (ANOVA) results showed the effects of variety on peeling efficiency and feed rate on output capacity as highly significant (P=.01). Also, the interaction of speed and variety on peeling efficiency and the effect of variety on output capacity was significant (P=.05). The interaction of variety and speed at 480 rpm achieved a maximum mean peeling efficiency of 55.6% for Bawondoya. Similarly, at slightly higher speed of 510 rpm, the maximum mean peeling efficiency of 64.6% was achieved for Bartita. Flesh loss value of 0.84% was the least obtained and this was for Bartita while the highest flesh loss of 1.43% was observed for Nicola. At feed rates of 50 g/sec and 60 g/sec; the minimum and maximum output capacities of 31.3 kg/h and 59.2 kg/h were obtained respectively.
