Abstract: Chickpea (Cicer arietinum L.) is an important legume crop in Ethiopia. However, the productivity of the crop is very low due to a number of constraints out of which soil nutrient depletions a serious problem. Field experiment was conducted in 2015/16 in Goro, Bale Zone, Oromia Regional State to determine the effectiveness of Rhizobium strains and phosphorus fertilizer application on two varieties of chickpea (Arerti and Habru). The thirty treatments included: two Rhizobial inoculants (EAL018andEAL029), five P2O5 rate (0, 15, 30, 45and 60 kg P2O5 ha-1); and two varieties of chickpea (Arerti and Habru). The experiment was set up in split plot design with factorial arrangement of two varieties of chickpea on the main plots and five levels of P2O5 and two types of Rhizobium in the subplot. Flowering date and plant height (PH) were significantly affected due to varieties, application of P2O5 and Rhizobium inoculation. The shoot dry matter production, number of primary and secondary branch, maturity date, number of pod and seed per plant, above ground biomass (AGBM), grain yield, thousand grain weight, were significantly affected by variety, rhizobium inoculation and application of P2O5. Maximum response was obtained from EAL029 strain inoculation and application of 45kg P2O5 ha-1 for dry matter production, number of pod and seed per plant, AGBM and grain yield. However, increasing P2O5 applications from 45 to 60 kg ha-1 provide maximum thousand grain weight respectively. The current investigation indicated that Arerti variety inoculation with Rhizobium strain EAL029 along with application of P2O5 at rate of 45 kg ha-1 found to be appropriate for chickpea production in the study area. Since the experiment was conducted only for one year, we suggest the results to be verified with more varieties of chickpea and rhizobium strain under the same agro-climatic conditions.

Abstract: Plants provide space for the occurrence of different trophic groups of nematodes. The occurrence of nematodes near the rhizosphere of plants, such as parasitic, free-living etc. can determine the survival of plants and finally the production of plants. Altogether 40 samples from the 30 cm apart from the kiwi plants were tested to identify the distribution of nematodes in Kiwi plants at Central Horticulture Centre, Kirtipur, Kathmandu, Nepal. All together 10 genera of nematodes including both free living/beneficial and parasitic were identified during the study period. Overall, 830 individuals of 10 nematodes were found to be associated with Kiwi plants, among them order Rhabditida was reported to be the highest (40.96%) which was followed by Mononchida (33.74%), Dorylaimida (15.66%) and Tylenchida (9.64%). These four genera of plant nematodes have been reported for the first time associated with Kiwi plants in Nepal. The result indicated that the nematodes are not significantly distributed in all Kiwi plants. For more production we recommend proper management of manures and Kiwi plants treatment.

Abstract: The agricultural sector significantly contributes to the economic growth of every country. This sector faces challenges with respect to producing the right quantity and quality of food. Most traditional methods used in growing crops are inadequate to ensuring food security. This challenge can be addressed by applying Information and Communication Technology (I.C.T.) in the agricultural sector. In the cultivation of crops, the use of proper irrigation method is essential in enhancing the growth and yield of crops. This research focuses on the application of information technology to provide the required amount of water needed by crops for growth. With the emergence of Internet of Things (IoT) which involves the interconnection of electronic devices to the Internet and the acquisition of data from these devices through the use sensors, an IoT based Intelligent Irrigation System was built. The Intelligent Irrigation System consisted of a transmitter and a receiver circuit (which is connected to a water pump via an actuator). The transmitter circuit was responsible for reading the moisture content of the soil and transmitting it wirelessly to the receiver. The receiver then made decisions on whether to trigger the pump on or off depending on the received soil moisture data. The Intelligent Irrigation System was piloted on a carrot farm. A total of 16 beds were constructed for the study. It was divided into 2 different blocks. The first block comprised of 8 beds which were manually irrigated and the second block was made up of 8 beds which were irrigated by means of machine-to-machine (M2M) communication. For pre-harvest, the performance indicators used were the height of the plants and the number of leaves per plant. The weight, length and diameter of the carrot plants were used as performance indicators for post-harvest. It was realized that the crops that were watered via M2M communication showed better growth performances as compared to those that were watered manually.
