Among genotypes, Dekalb 900 M Gold recorded significantly higher dry matter/plant, LAI, cobs placement height, grain yield, nitrogen content, protein content, protein yield and protein productivity than other genotypes. Leaves/plant and phytosynthetically active radiation (PAR) above canopy did not influenced by genotypes. Dry matter/plant, plant height, LAI, cobs placement height, protein content, protein yield and protein productivity exhibited higher under highest levels of nitrogen (160 kg N/ha), but at par with 120 kg N/ha. However, grain yield (6300 kg/ha) was highest under nitrogen levels of 120 kg/ha, but also at par with 160 kg N/ha (6240 kg/ha). The effect of applied nitrogen was found non-significant in respect of leaves/plant, PAR above and below canopy, photosynthetically active radiation interception and days taken to tasseling and silking.

Sugarcane is a major commercial crop consuming more labour force for planting. Sugarcane planting is a time consuming and labour intensive operation in sugarcane cultivation. In the traditional method in India, all the sugarcane cultivation processes are carried out by manual labour except land preparation. Sugarcane planting requires manual power and a pair of bullock or a tractor with ridger to plant sugarcane setts in one hectare on an average. Although number of useful machines have been designed, developed and being manufactured for cultivating sugarcane, but due to lack of extension and socio-economic reasons, still majority of the farmers are using indigenous tools and equipments. Shortage of timely labour availability and exorbitant wages compel our farmers to limit their acreage under sugarcane crop. Therefore there is an urgent need to mechanize sugarcane planting operations for reducing the cost of planting, as well as, for reducing the human drudgery involved. The field trials of Khalsa Make three row automatic sugarcane planter was conducted for planting of sugarcane at farmers' field as well as at research farm. The performance indicators of the planter viz. field capacity, efficiency etc. were calculated. The effective field capacity was 0.38 ha/h with field efficiency up to 70.4%. © 2012 Society for Sugar Research & Promotion. Source

The high seed rate and labor requirement are common problems associated to traditional sowing of bold seeds. For bold seeds such as maize, cotton, groundnut and pigeon pea planting and fertilizer placement are the two different unit operations performed either by tractor drawn planter or manually. Performance of tractor-drawn, commercially available raised bed planter for planting of wheat at the bed was tested. The machine has trapezoidal hopper and an inclined plate type metering unit. A suitable furrow opener system was equipped with the machine to place the seeds at the bed at desired depth. The power transmission to the metering unit is through a ground wheel by chain-sprockets system. The field trials were conducted for sowing of different seeds at farmers' field. The performance indicators of the planter viz. field capacity and efficiency were calculated by using the observed data in the field. An average field capacity of 0.28ha/h to 0.31 was obtained for continuous operation of raised bed planter at an average speed of 2.27km/h. A field efficiency of 71-73% was observed which was in the prescribed range of 65-75% for row crop planter. The average depth of placement of seed of 10 observations randomly selected was 4.1cm. The field machine index was recorded at an average of 77.38%. The seed rate obtained was 91kg/ha for wheat and depth of sowing was 38-45mm. Average plant population (plant/m2) after germination was found under the prescribed range i.e. 141-171. © 2012 Elsevier B.V. Source
