Abstract

An poly-pot experiment was conducted in factorial R.B.D. design with 4 replications to study the effect of nitrogen and phospborus on the growth and yield of bamboo seedlings. Application of nitrogen @ 5.0 gm and 10.0 gm of urea/pot containing 2 kg soil individually as well as in combination with single superphosphate significantly decreased all growth parameters and dry matter yield. However, phosphorus application @ 10.0 gm and 20.0 gm single superphosphate/ pot individually as well as in combination with nitrogen increased the height of plant, length of rhizome and dry matter yield. The correlation coefficients between some growth factors were calculated and were found highly significant. The results of this experiment suggest that with 'P' application better growth of bamboo seedlings may be obtained in short duration and healthy plantation stock could be made available.

Abstract

Germination studies on the seeds of four forest tree species viz. Dendrocalamus Strictus (Bamboo) of Betul and Amarkantak origin, Emblica officinalis (Awala) and Acacia auriculiformis (Australian Babul) were performed in different artificially prepared saline water of 3, 6, 9, 12 and 18 mmhos/cm electrical conductivity adjusted in Hoagland solution 1 by incorporating neutral salt, NaCl. Tap water was the control whose Electrical conductivity was .56 mmhos/cm and fresh Hoagland solution contained 1.76 mmhos/cm E.C. Germination data were subjected to statistically analysis with 7 treatments and 8 replications in factorial design. Eamtoo may tolerate higher salt concentration. Bamboo of Amarkantak origin may prove to be better In high salinity conditions, however the same may be very detrimental for the germination of Awala. Australian Babul may not fair well in salt affected conditions.
