Trends in Indian rainfall records have been extensively studied but the subject remains complicated by the high spatiotemporal variability of rainfall arising from complex atmospheric dynamics. The aim of this work is to study the variation in rainfall pattern and classification of Agricultural products imports in Tamil Nadu. The dataset relates to monthly rainfall from various districts of Tamil Nadu for the period of January to December, from the Indian Meteorological Department we collected. The time frame of the data used in this study is 2007-2013. In this research article, we applied, K-means clustering technique and correspondence method. The cluster group are compared with agricultural product import during the year 2007 – 2013.

Some engineering properties of Rubus fruticosus fruits were characterized in order to provide fundamental information about their properties that will aid in designing modern technology for their handling, processing, storage, preservation, quality evaluation, distribution and marketing. The engineering properties studied are electrical properties.  The fruits samples of moisture content (5, 15, 30, 45, 60% (wb)) were conditioned to four different temperature levels, respectively before testing. American Standards for Testing and Materials (ASTM) and American Society of Agricultural and Biological Engineering (ASABE) standard procedures were used to test all the properties considered. Genstat, Mathlab, JMP in SAS, Duncan in SPSS and Microsoft excel statistical packages were used to analyze the generated data and the means were compared using the analysis of variance (ANOVA) at 5% level of probability. Dielectric constant and loss factor of the fruits decreased with increase in frequency (200 MHz – 20 GHz) and increased with temperature. The study was carried out in Anambra State Nigeria and took duration of 9 months. This information is recommended for design and development of efficient and effective technology for mechanizing Rubus fruticosus products.

The field experiment was conducted at the Horticultural farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka -1207 during the period from October 2014 to March 2015 to find out the efficacy of different organic manures and different varieties on the growth, yield performance of organically grown tomato. The experiment comprised of two different factors: Factor A. four types of organic manure [M0= Control (No organic manures application), M1 = Cow dung (30 t.ha-1), M2 = Poultry manure (25 t.ha-1) and M3 = Vermicompost (20 t.ha-1)] Factor B. three types of variety V1 = BARI tomato 15, V2 = BARI tomato 14 and V3 = BARI tomato 2. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Encouraging responses were monitored in all respects. Among the treatment combination M2V1 (Poultry manure + BARI Tomato 15) showed the highest plant height, maximum number of flower cluster, number of flower per cluster, number of fruits per cluster and number of fruit per plant with improved fruit size. The maximum yield (86.25 t/ha) was recorded from the treatment combination of M2V1 (Poultry manure + BARI Tomato 15), while the treatment combination of M0V3 (Control treatment + BARI Tomato 2) gave the minimum yield (31.25 t/ha). Therefore, BARI Tomato 15 coupled with poultry manure can be the most suitable for enhanced yield and can be considered a noble practice in sustainable agriculture.

Aim:  An experiment was conducted to assess the performance of growing snails fed maize-based concentrate and maize supplemented with Cola rostrata seed meal in addition to forage mixtures. 

Methodology: A total of eighty eight (88) growing snails with weight ranging from 94.45g - 94.73g  were randomly allotted to four treatment groups (T1, T2,  T3 and T4), replicated two times with eleven (11) snails per replicate in a completely randomized design (CRD).The snails on T1 were fed maize-based concentrate only, T2 were fed with maize concentrate supplemented with 40% cola rostrata seed meal, T3 were fed with forage mixture and maize-based concentrate while, T4 consisted of snails fed forage mixtures and maize concentrate supplemented with 40% Cola rostrata seed meal. The feeding trial lasted for fifty six (56) days.

Results: The results showed that the mean final body weight and total weight gain were higher for T4. More so, feed conversion ratio (FCR) of T4 was equally as good as that of the control (T1).

Conclusion: Diets comprising, maize-based concentrate with 40% Cola rostrata seed meal supplementation and leguminous forage mixtures gave better growth performance when compared with other treatment diets and therefore for optimum growth performance of Archachatina marginata it was recommended.

A pot experiment was conducted to investigate the effect of coconut oil cakes on the growth performance of gima kalmi (Ipomoea aquatica). The experiment was laid to fit a completely randomized design (CRD) with three treatments (5, 10, 20 tonha-1) of coconut oil cake treatment along with control (no oil cake) each having three replications for this experiment. After plant harvesting, the laboratory investigation was carried out in the Soil, Water and Environment Discipline, Khulna University, Khulna, Bangladesh. Yield contributing characters like plant height and leaf number were significantly (P <0.05) influenced by different treatments. Among the three treatments applied 20 tonha-1 treatment has shown highest response to plant growth due to nutrient availability of the soil. The sequence of response was in the order 20 tonha-1>10 tonha-1>5 tonha-1 significantly (P <0.05) difference in plant growth from the control (0 tonha-1). But the application of organic manure as coconut oil cake, decrease in soil pH was probably due to the production of organic acids during organic manure decomposition or by nitrification and EC value of soil was increased with different treatments. In addition, increased the organic carbon of the soil. Organic carbon increased due to the application of organic manure but insignificantly.
