Abstract/Description: | The experiments were conducted during 2007 and 2008 under simulated shade net house conditions by growing crops namely green gram (Vigna radiata L.) and soybean (Glycine max L. Merril.) with three different regimes of shade (33, 50 and 75%) or without shade as control (open sunlight) to test the influence of shade on the phenology of crops beginning with the germination. Although seed germination was successful (93% to 100%) in all the three regimes of shade and open field, germination was faster in shade than open field in both the crops. However, there was differential response with the requirement of days to achieve maximum germination between the crops where green gram showed faster rate of germination than soybean. Time taken for leaf maturity or full expansion varied with the crops and the intensity of shade. Expansion rates of leaf length (LER) and lamina width were higher in shade than in open field. These were faster in green gram than soybean. However, degree of difference in LER between shade and open grown plants was less in soybean than in green gram. In green gram, flowering initiation was observed within 31-38 DAS (days after sowing) either in open field or 33% shade and within 34-40 DAS in 50% or 75% shade. In soybean, flowering initiation was observed within 33-41 DAS in all the three regimes of shade and it took relatively more time to flower initiation in open condition i.e. 37-44 DAS. A trend similar to flowering initiation was also observed in pod formation in green gram and soybean. The observed consistent trend for all the parameters of crop phenology indicate a relatively better shade adaptability in terms of its resilience to shade induced changes in crop phenology in soybean than green gram in a semi-arid region. |
