Birajdar And Suryawanshi Jaipal H | | Abstract : The The transformation in the pattern of agriculture in Ahmednagar
district, which has been transformed from extensive to intensive use of
land owes largely to the extension of irrigational ficilities. The district facing
rainfall vagaries and wide variability of rainfall from the last few decades.
The changes owe a great deal to variety of infrastructural developments
and increase inputs in general and extensive and intensive irrigational role
in particular. An attempt is made here, to study the impact of imitational
changes on agricultural characteristics of the district which is existed after
the advent of irrigation. Ahmednagar district has different sources of
irrigation sources well, canal lift and other sources. The important sources
available in the district are well and canal. Jowar, Bajore, Wheat account
for a major share of cropping of land under tillage in the district. With the
advent of irrigation, the shares of commercial crops are increased in total
cultivated area of the district. The traditional subsistence agricultural
structure of the study region appears to be crumbing or is in the process of
transformation into market oriented, semi-commercial ized pattern. | | | | Author Profile | Full-Text PDF | |
| | | 30 | Effect Of Pre-treatments On Seed Germination Of Some Acacia Species (Acacia Tortilis (Forsk) Hayne, Acacia Senegal (L), Acacia Leucophloea (Roxb.) Willd | | By : M.R. Khan | | Abstract : Acacia species mainly grown for development of greenery, wood Gum and some other medicinal purposes. Particularly arid environment is often Acacia species show poor germination and low seedling establishment information on seed biology and germination behavior and dormancy pattern of these valuable Acacia species is lacking we investigate the germination of three deferent Acacia species (Acacia tortilis (forsk). Hayne Acacia senegal (L) and Acacia leucophloea (Roxb) Willd required for in N2 fixation and rehabitation of arid and semi arid areas. One year old seeds were used for laboratory testing at times fail to germinate properly. This failure may be due to the state of seed dormancy, different treatment were applied in order to find the best treatment for enhancing the germination percentage of Acacia species. The seeds were Pre-treated with sand paper and with also H2SO4 and then H2O2 the highest germination percentage in all three species tested, mechanical scarification, hot water treatment growth regulator GA3 treatment were resulted better germination up to 72% The study proved that seed treatment are necessary to overcome dormancy in Acacia species. | | | | Author Profile | Full-Text PDF | |
