Experiments were conducted in an Oxisol in an attempt to clarify the role of Zn in crop production. The Capo fertilizer-yield equation was applied to the first of two consecutive corn crops of Pioneer X-3068 and Funk's G-795W, grown in an exposed Coto clay subsoil. The equation made possible the estimation of grain corn yields with a fair degree of precision. A crop of a white-fleshed sweet potato cultivar (Mina) was grown in a typical undisturbed Coto clay near the site where the corn experiments were conducted. Near maximum yields could be obtained with the application of only 3.3 kg/ha of Zn. Stover yields were estimated with a very high degree of precision (r2 = 0.98) from the corresponding equation. No response to Zn was obtained in the second consecutive corn crop (Funk's G-795W) nor in the sweet potato crop.

ABSTRACT This study aimed to evaluate sweet potato performance in succession to annual herbaceous leguminous plants, in monocropping or intercropped with corn, under agroecological management, under Baixada Fluminense conditions. The experimental design was randomized blocks, with five treatments and four replicates. The treatments consisted of pre-cropping with the following species: crotalária (Crotalaria juncea) under monocropping system, crotalária intercropped with corn (Zea mays), jack bean (Canavalia ensiformis) under monocropping system, jack bean intercropped with corn and spontaneous vegetation. The results showed that monocropped crotalária reached the greatest dry biomass accumulation during two consecutive years of succession. In the second year, this treatment provided greater accumulated amounts of N, K and Mg in plant biomass. Growing sweet potatoes in succession to the pre-cropping of crotalária is advantageous, as it provided an increase in vegetable productivity in the second year of succession.

Two herbicide experiments were carried out in 1980 to evaluate Alachor and Metribuzin alone or combined for weed control in sweet potato cultivar Miguela at the Isabela and Fortuna Substations, Metribuzin at 1.12 kg ai/ha rate controlled effectively both broadleaf weeds and grasses. A minimum rate of 6.73 kg ai/ha of Alachor was needed for acceptable weed control. Metribuzin at the 1.12 kg al/ha rate in combination with Alachor at the 3.36 kg ai/ha rate provided the best weed control. There was no visible herbicide injury to sweet potato plants at the Isabela Substation. Moderate crop injury as a consequence of Metribuzin application at 2.24 kg ai/ha was apparent at the Fortuna Substation. The highest tuber yield was obtained with Metribuzin at 1.12 kg ai/ha in combination with Alachor at 3.36 kg ai/ha at both Substations. Metribuzin at 1.12 kg ai/ha rate alone or in combination with any other herbicide also produced good tuber yield. Sweet potatoes with standard herbicide treatments, Diphenamid and Chloramben, yielded poorly because of weed competition.

Abstract The rate of world population growth gets faster every year, while on the other hand the land available for food production activities is increasingly limited. Efforts to increase income and food crop production by using cocoa farming to support national food security can be done by optimizing of land through crop diversification patterns by planting local tubers under cocoa farming. This research aims to analyze the optimization of land use, revenue and production costs. In addition, analyzing the nutritional content contained in each type of local tubers, namely sweet potato, cassava and taro. The research was conducted in the the buffer zone of Lore Lindu National Park (TNLL), Palolo District, Sigi Regency, Central Sulawesi Province, Indonesia. The results showed that the optimization of land use and revenue was obtained through the diversification pattern of sweet potato and cocoa. Optimization of the costs use occurs in the use of fertilizer production inputs. In addition, sweet potatoes have a higher calorific value, protein and fat compared to cassava and taro. However, the carbohydrate content of cassava is higher than that of sweet potato and taro.

Irrigation systems may exhibit variations in performance when poorly dimensioned or depending on the time of use. In this sense, the objective of this study was to evaluate the performance of irrigation systems located by micro sprinkler and drip irrigation in the sweet potato crop in a family property in the municipality of Guaraciaba do Norte-CE. The property under study in this research has a total area of 2.5 ha. The area cultivated with sweet potatoes is 120 m2 with 50% of the area irrigated by drip irrigation and the remainder irrigated by micro sprinkler. In order to analyze the performance of the irrigation systems, the methodology proposed by Keller and Karmeli (1975) was adopted, in which the flow rates of the emitters are determined in pre-established positions. Were determined the coefficients of uniformity of Christiansen (CUC); coefficient of statistical uniformity (CUE); Hart uniformity coefficient and distribution uniformity coefficient (CUD). Irrigation systems presented uniformity coefficients higher than 90%, for all the equations applied in this work, both also presented application efficiency higher than 85%. Due to the high coefficients of uniformity found it was concluded that the irrigation systems located on the property were well sized and mounted

Time Of Harvest

Selotapak is one of the villages in the Trawas District area of ​​Mojokerto Regency, East Java. This village is one of the sweet potato producing communities. At the time of harvest, the harvest reaches 40-50 tons per hectare. But often at the time of harvest, the price of sweet potatoes becomes very low. This price makes farmers unable to benefit, even many who lose. On the other hand, the storage period of sweet potatoes is also not long. The farmers must immediately sell their crops. Therefore another alternative is needed in marketing sweet potatoes so that the selling price can increase. One way to do this is by processing sweet potatoes into other products with longer shelf life and higher prices. In this activity, training in preparing sweet potatoes into several products, namely flour, noodles, brownies, roll ice cream, and yoghurt. This activity can be done through PKK empowermen and several youth organizations. Based on the training results, over 80% of the training participants feel the benefits of the training,. The participants can practice it independently in producing this sweet potato-based product. By making sweet potatoes into flour, the storage period extended. Sweet potato flour can be used to make other food products that become superior products in the village of Selotapak. For the sustainability of sweet potato processing, it is necessary to cooperate with all village communities in marketing their products. The role of the village government is essential in this regard, for example, by requiring presenting sweet potato products (at least one piece) as consumption in each village activity. For the next steps, supporting training is needed for the development of superior village products, for example training in making packaging and marketing.

Sweet potato (Ipomoea batatas L.) is an economically important food crop in Eswatini. Since its introduction, numerous agronomic research activities were carried out in agricultural research centers, non-governmental organizations, and universities. However, information on the correct vine length for planting to improve sweet potato root yield in Eswatini is scanty. Therefore, this study aimed at helping farmers with the correct vine length to be used for improved growth and yield of sweet potatoes. A field experiment was conducted at the Luyengo campus, crop production farm during the 2019/2020 crops season. It was laid in a Randomized Complete Block Design (RCBD) in a factorial arrangement with three replicates. The treatments were vines planted with or without leaves and different vine lengths; 25 cm, 30 cm, and 35 cm. Kenya white variety was used. Data were collected on growth and yield parameters. Results showed that leaf removal yielded significantly (P<0.05) lower than non-leaf removal. This may be attributed to delayed photosynthetic activity in the former.  The Vine length had no significant effect on yield. It is concluded that vines with leaves be used as planting material, and the length of vines to be used for planting should be 25 to 30 cm.
