Self-propelled Walking Behind Type Rice Transplanter - A Better Alternative For Manual Transplanting

摘要

Rice transplanting by self-propelled transplanter ensures timely operation, saving in cost and minimum humai, arut-gery. A detailed economics of both manual and mechanical transplanting were worked out based on the study done at College of Agricultural Engineering, Bapatla during the year 2008-09. The self-propelled walking behind type rice transplanter gave net profits of Rs 1189 and Rs.1860 ha~(-1) when annual use of machine was one season (300 h) i.e kharif and two seasons (500 h) i.e both kharifand rabi respectively over manual transplanting. The field capacity, field efficiency and fuel consumption of the transplanter were 0.12 ha ha~(-1), 58.39% and 5.10 I ha~(-1) respectively. The grain yield in respect of mechanically transplanted rice cropwas 5.13 t ha~(-1) and incase of manually transplanted rice crop was 4.57 t ha~(-1). 12% more yield and an additional income of Rs. 8339/ha were realized for mechanical transplanting over manual transplanting.
