The population of marginal farmers in India is bound to increase due to continued division of farm holdings. Characteristically, marginal farmers are having more family labours but the production and productivity of their land holdings is low. The foremost reason behind this is the erratic rainfall and lack of assure supplementary irrigation during long dry spells. This paper presents the scope and applicability of a diaphragm based treadle pump in Bihar where groundwater is abundant and available at shallow depths round the year. Therefore, this pump could be very useful for marginal farmers in improving production and productivity of their tiny piece of land, as it uses human power and can be operated by male and female of age group 32- 45 years and lifts water from a depth ranging from 0- 30 feet. The water saving technologies such as bucket kit drum kit etc. could be used with this pump to irrigate the crops with high water productivity.

Twelve local maize populations were evaluated at the experimental farm, University of Prishtina, Kosovo. The study was conducted to assess the magnitude of genetic variation in local maize populations for different morphological-physiological and chemical composition under field and laboratory conditions. Randomized complete block design (RCBD) with three replications was used for laying out the experiment. The results showed that there were significant differences for most morphological and physiological traits under study. The mean grain yield of all populations was 102.96 g plant-1. The protein and oil contents ranged between 11.53 to 9.43% and 4.23 to 4.87% respectively. The cellulose content varied from 6.03 to 6.37%. There were also big differences regarding phenotypic correlations. The present study revealed considerable amount of diversity among the local maize populations which could be manipulated for further improvement in maize breeding.
