In this paper an attempt has been made to analyse the agricultural landuse pattern at micro level in Solapur District. This study is based on secondary data collected from secondary records. Agriculture production is influenced by physical, climatological, socio-economic, technological and organization factors. An Endeavour is made here to study crop combination regions in Solapur District for year 2004-2005. This is normal year for agriculture phenomenon in this district. The crop data has been computed with the help of Weaver’s technique of crop combination. Solapur district occupies southern part of Maharashtra state. It occupies an area of 14,84559 sq.km. And supports 32.32 lack of population in 2001 censes. Administrative the district is divided in to eleven tahsils. Physiography, temperature, rainfall, soil and drainage influence on agriculture landuse pattern in this district. Temperature is high in summer. Because of district is located in drought prone area of Maharashtra. Rainfall varies between 200 to 600 millimeters rainfall from west to east in entire district. Thirteen crops have been considered for crop ranking and crop combination. Among these, jawar, wheat, bajara, sugarcane, gram, maize, safflower, cotton, etc. are the major crops. By computing crop ranks and crop combination in Solapur District has identified ten crop combination. Such type of study represents real situation of cropping pattern in Solapur District and helps to planners, agricultural scientists and research scholars.

The research was conducted to examine the effects of supplementation of Nigella sativa seeds to the broiler chicks’ diet on the performance and carcass quality. A total of 96 one – day – old unsexed broiler chicks (Hubbard) were used. The experiment lasted 5 weeks (8 – 42 day). Three experimental diets were supplied ad – libitum. 1% whole crushed Nigella sativa seeds (WCNSS) were added to the first experimental diet. To the second diet 2% Nigella sativa seeds was added. The third one which is the control was free of whole crushed Nigella sativa seeds (WCNSS). Supplementation of ground black seeds to the broilers chicks diet resulted in a significant (P< 0.01) decreased in feed consumption, body weight gain and live body weight. Birds fed on diet supplemented with 1% whole crushed Nigella sativa seeds showed a significant (P< 0.05) reduction in dressing % when compared to those fed on control or 2% supplemented diets. Addition of ground black seeds had no significant effect on feed conversion ratio liver, gizzard, heart and abdominal fat %. It was concluded that addition of 1% or 2% whole crushed Nigella sativa seeds to the broiler chicks diet produces adverse effects on the performance and carcass quality.

Field experiments were conducted in 2007 and 2008 at Calabar in the south eastern rainforest zone of Nigeria to evaluate the response of okra (Abelmoschus esculentus (L.) Moench) to four rates of nitrogen (0, 40, 80 and 120kg/ha) and three rates of lime (0, 5 and 10t/ha). Factorial combinations of the treatments were laid out in a randomized complete block design with three replications. Nitrogen had significant effects on plant height, number of leaves and branches/plant, number of pods/plant, fresh pod weight and total fresh pod yield. The 80kgN/ha rate maximized all the growth and yield attributes. Lime application had no consistent effect on plant height and number of branches/plant; but significantly improved all other growth and yield attributes. Total fresh pod yield was highest at 5t/ha lime rate, and this was 91% higher than the control. Significant interactions were recorded between nitrogen and lime on number of leaves/plant and fresh pod yields, with the combination of nitrogen and lime at 80kg/ha and 5t/ha giving the highest values.

The study was carried out to automate the operation of the ‘Bobcat’ tractor for the farming purpose. Bobcat tractor is a hydrostatic tractor that uses levers for steering, breaking and the forward and backward movements. Two set of screw shaft driven by car power window motor were used to move the two levers. The computer program was written to automate the movement of each lever. Bobcat tractor move straight forward when both levers move forward and vice versa. Bobcat tractor will turn left when only the left lever is moved forward and vice versa. The friction between the levers and the attachment was a major concern in this project. The bearing was introduced and the existence space between the levers and the attachment can solve the friction problem. Autonomous tractor increases the effectiveness of the field with little or no help of supervision.

Cyanobacteria are the pioneer oxygenic, gram negative photosynthetic prokaryotes distributed in almost all conceivable habitats. Cyanobacteria exhibit great diversity of forms and functions. Gunupur is a part of the southern belt of Orissa, rich in Cyanobactrial biodiversity in paddy ecologies. The study aimed to characterize the abundance and occurrence of Cyanobacteria in various paddy fields of Gunupur, identify the isolates and determine diversity indices in relation to the genera wise distribution .Average population counts of various locations brought out the major diversity among the locations sampled. This study indicate the maximum occurrence and abundance of Oscillatoriaceae and Nostocaeae in all sites of the Gunupur and Stigonemataceae shows less occurrence.
