Rice is one of the most important cereals that hold the key for food security. SRI has reached certain level of acceptance among the research and scientific community in major rice producing countries. The SRI method of rice cultivation involves planting single seedling in wider row spacing i.e., 25x 25 cm, which involves more labour intensive and laborious process. Hence, the present study was conducted with an objective to compare the mechanized rice transplanting with different intra row spacing with mechanized rice transplanter method with SRI and normal method of rice cultivation. The study was conducted with four treatments i.e.,T1 - Machine transplanting at spacing of (30 x 14 cm), T2 – Machine transplanting at spacing of (30 x 18 cm), T3 - Machine transplanting at spacing of (30 x 20 cm), T4 - Machine transplanting at spacing of (30 x 22 cm) and T5 - Manual transplanting at spacing of (20 x 15 cm) (control). The study indicated that mechanized transplanting with rice transplanter adopting highest yield of (30 x 20 cm) row spacing recorded more 10.00 per cent more yield, when compared to 30 x 18 cm) method of planting. Mechanised paddy farmers were able to secure a net income Rs. 1.81/- per every rupee of expenditure. While, the convectional paddy farmers realized Rs. 1.42/-.Keywords

This study was conducted to investigate on alternative tray filling materials to replace the soil media on crop growth, yield characteristics and yield attributes in The Mechanized System of Rice Intensification (MSRI). Focusing on the different alternative filling materials suitable to replace the soil media with 100% seed germination, Ten treatments with different combinations were experimented and a fine thin layer of well decomposed farm yard manure was spread over all ten treatments o bed filling material [(i.e., T1-10% groundnut shell + 90 % soil; T2-10% vermincompost+ 90% soil; T3-10% rice husk+90% soil; T4-25% vermin-compost+75% soil; T5-25% rice straw + 75% soil; T6-25% rice husk + 75% soil; T7-10% rice straw+ 90% soil; T8-25% groundnut shell +75% soil; T9-Field soil (100%) (MT); T10-Manual plantin (MP)]. The observation of transplanted hills was also noted in ischolar_main growth and leaf number, leaf area index and number of tillers and panicle number, panicle length and grain number per panicle, grain filling and 1000-grain weight and straw weight. The raising nursery with different bedding materials transplanted with machine significantly influenced grain yield per hectare. The results revealed that highest grain yield per hectare was observed with T8 (25% GS) as 4858.5 kg/ha and followed by T4 (25% VC) as 4685 kg/ha. However, the lowest grain yield was recorded at 2212.6 kg/ha was observed in T6 (25% RH), due to lowest N, P, K contents in rice husk bed material. It is also observed from transplanted crop that ischolar_main length was highest with T5 (25% RS) as 11.39 cm followed by T3 (10% RH) as 11.16 cm, whereas lowest ischolar_main length 9.10 cm, ischolar_main spreading was highest with T8 (25% GS) as 20.72 cm followed by T1 (10% GS) as 19.46 cm, T2 (10% VC) as 19.00, T4 and 9 are comparable with each other and is 18.47 cm. whereas lowest ischolar_main spreading 13.08 cm was observed in T10 (manual planting). Finally it has been concluded that there is significant effect of bedding materials on crop growth and yield parameters.Keywords
