We studied the effects of various cytokinins and urea derivatives on germination of aged seeds of in Lotus corniculatus L. The following substances were applied: N6-isoprenoid cytokinins (isopentenyl adenine and zeatin), adenine sulfate, N6-aromatic cytokinins (kinetin, benzyladenine) and their N9-ribosides, N-benzyl-9-(2- tetrahydropyranyl)adenine, and urea derivatives (diphenylurea, thidiazuron, and chloro-pyridyl phenylurea). With the exception of adenine sulfate, all cytokinins increased the percentage of seed germination up to twofold, depending on their kind and concentration. It is concluded that cytokinins may be among the missing factors in aged seeds of L. corniculatus contributing to the implementation of their full germination potential. They could be used to improve germination of both freshly harvested and aged seed samples, if necessary. .

Ageing Period

Seed deterioration is a serious problem in developing countries where seeds are stored in places usually without a proper control of humidity and temperature. In this investigation, an effort was made to identify crops as well as varieties of brassica spp. tolerance to ageing and predicting loss of seed viability at regular interval through standard germination under laboratory condition. Analysis of variance showed that mean squares due to crops, ageing periods and crop× ageing period were significant for % seed germination. Result revealed that standard germination declined from 95.63 to 37.54% in toria, 92 to 28.96 in yellow sarson, and 93.79 to 30.92% in mustard. Similar changes in germination % were observed at 9 and 12 months of observation. After 6 months, germination % declined from 95.13 to 35.50% in toria, 91.87 to 28% in yellow sarson and 93.33 to 29% in mustard. Analysis of variance showed significant differences for %seed germination due to varieties, ageing period and interaction of varieties × ageing periods. At varietal level AP2, AP3 and AP4 aged seed, Bhawani (82.66%, 68.16% and 28.17%) showed higher seed germination % respectively than other three varieties of toria. In case of yellowsarson and mus-tard least deterioration for standard germination were observed in B-9 and Kranti respectively.This study indicates that toria seeds have better storability than yeloowsarson and mustard. At varietal level good storage potential was found in Bhawani, B-9 and Krantivariety of toria, yellow sarson and mustard respectively than other three varieties of studied crops.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.
