A field experiment was carried out to evaluate the influence of ground and unground rice straw application as organic manure on the yield and proximate composition of groundnut seeds, at the University of Ilorin teaching and research farm. The field layout was a split plot Complete Randomized Block Design with four replications. The ground and unground rice straw were in the main plot and different application rates of the rice straw (0; 1,250; 2,500; 3,750 and 5,000 kg /ha) were in the subplots. The results revealed that ground and unground rice straws at 1,250 and 2,500 kg/ha application rates significantly increased (p < 0.05) yield attributes such as pods’ number with a range of 48.33-74.33 pod weight (23.95-42.70), number of seeds (45.67-77.33), seeds’ weight (13.55-25.56 g) and hundred seed weight (34.34-38.05 g) as well as some aspect of proximate composition such as ash content, crude protein and crude fats which ranged between 2.71-2.79%, 31.47-31.56% and 46.61-47.13% respectively, in order of their mention. The forgoing study revealed that ground and unground rice straw applied at the rate of 1,250 and 2,500 kg/ha can serve as an alternative for soil nutrient amendment in groundnut as it ensured a reasonable yield that is able to meet the nutritional needs of man and livestock.

Maize yield represents the interaction between genotype and environment. An excellent genotype should have high mean yield and small variation across common locations.This information could be obtained through yield performance test and stability analysis of yield data obtained from multilocation trials. This research was aimed to find out yield stability of eight early maturing maize promising lines at five sites using the AMMI method. There were total 12 genotypes of maize hybrids used in this research, consisted of eight hybrids (CH-1, CH-2, CH-3, CH-4, CH-5, CH-6, CH-7, and CH-8) and four check varieties (Gumarang, Bima 3, AS-1, and Bisi 2). This research was conducted at five locations ie. Gowa (South Sulawesi), Donggala (Central Sulawesi), Manado (North Sulawesi), Probolinggo (East Java) and Lombok Barat (West Nusa Tenggara) from April to September 2013. The treatments were arranged in a randomized complete block design (RCBD) with 3 replications. Variable measured was grain yield at all trial locations. Analysis of variance was performed for each site data to determine the performance of each genotype at each location. Results showed that genotype CH-2, CH-4 and CH-6 were considered as stable genotypes. Genotype CH-2 and CH-4 have a potensial to be released as new early maturing variety, due to its high yield of 8.71 and 7.52 t/ha averaged over 5 locations. Genotype CH-6 yielded below the mean yield of all genotypes, while genotype CH-8 was adaptive to a specific location, such as in Donggala, with yield of 8.38 t/ha.

<p class="AbstractTitle">ABSTRACT<br /><br />Maize is commonly developed in dry land areas with limited irrigation water in Indonesia, thereby posing a threat to its poductivity. Thus, availability of early harvest varieties able to adapt to limited water is important. The aim of this study was to analyze the performance of maize hybrid genotypes candidates in dry land. The research was conducted from April to July 2016 at Gowa, South Sulawesi. The experiment   was designed with a randomized complete block design consisting of 8 genotypes, namely GJ1, GJ2, GJ3, GJ4, GJ5, GJ6, GJ7, GJ8, and two control varieties, i.e., Bima 7 and Lamuru.  The results showed genotypes GJ1, GJ6, GJ7 and GJ8 had higher plant growth as compared to Bima 7 and Lamuru.  All genotypes were harvested less than  90 days. Genotypes GJ6, GJ7, and GJ8  yielded 6.85 tons ha-1, 6.51  tons ha-1 and 8.31 tons ha-1, respectively, which were higher 13-45% than the Lamuru control variety. Because this experiment was carried out in an optimun condition, it would be necessary to further study the three genotypes in drought stress conditions before being developed for early harvest and high yielding hybrid varieties.<br /><br />Keywords: early harvest, genotype, maize, performance<br /><br /></p>

Abstract One of the strategies to increase maize production is by selecting the proper combination among variety and planting density. The plant density population experiment was carried out to identify the candidate of maize variety that has high productivity with limited sunlight levels. Our hypothesis was how the erect leaf maize type can get optimal sunlight and affect the productivity. The study was conducted in IP2TP Bajeng, Gowa, South Sulawesi from March to June 2020. This study was designed under split plot design where spacing or plant density as the main plot with 3 levels of treatment (70 cm x 20 cm (population 71,428 plants/ha), 60 cm x 20 cm (population 83,333 plants/ha) and 50 cm x 20 cm (population 100,000 plants/ha). Furthermore, eight genotypes of hybrid maize (ERC 01, ERC 02, ERC 03, ERC 04, ERC 05, ERC 06, ERC 07, ERC 08), including control varieties (JH 45 and Pioneer 36) were treated as the sub-plots. The results indicated that the maize yield increase in line with the increase in plant population. The plant’s spacing of 70 x 20 cm with 100,000 plants/ha was produced 10.61 t/ha, significantly higher than other treatments.

Abstract Planting sorghum twice a year on dry land is constrained by the short duration of rainfall, so it requires technology to increase yields with the ratoon cropping system. The research was carried out in Agricultural Technology Research and Assessment Installation of Bajeng, Gowa, South Sulawesi from March to October 2019. The superior genotypes of sorghum were planted on marginal land as the main crop with a spacing of 75 cm x 20 cm (66,666 plants/ha). The ratoon plant used a split-split plot design. The main plot consisted of two mulches: M1=no mulch + 50% dose of main crop fertilization and M2=sorghum stover mulch + biodecomposer 1kg/ha without NPK fertilizer. The sub-plots consisted of 2 populations: P1=population of 66,666 plants/ha (1 shoot/hole), P2=133,332 ratoon plants/ha (2 shoots per hole). The sub-sub-plots consisted of 5 (five) genotypes/varieties of sorghum: V1=Numbu, V2=No.58-1, V3=No. 86.1, V4=No.103-1 and V5=No. 113-1, so that 20 treatment combinations were obtained with 3 replications. The results showed that to obtain high grain yield in ratoon cultivation in dry land, NPK fertilization (150-100-50)/ha is still necessary. The increase in population density of ratoon from 66,666 to 133,333 plants/ha significantly affected the increase in grain yield. Sorghum genotype No. 58-1, No. 86-1, No. 103-1 and No. 113-1 is technically and economically feasible to be developed in the cultivation of the double harvest ratoon system with the profit (Rp 10,989,000-12,247,500/ha) from the cultivation of sorghum once the main crop (Rp 4,003,000-4,856,000). The R/C value is 2.00-2.10 and the MBCR value is 2.27-2.38.

Many see organic agriculture as the most sustainable form of farming and as the paradigm for global food production in the future. One of the solutions to food insecurity and malnutrition in Sub-Saharan Africa is to promote local crops, encourage the use of locally source materials as amendment, improve their traditional system of production, and so diversify subsistence crop. The major reasons are the lack of knowledge and skill in land preparation and agronomic practices, weather uncertainties, pest outbreak and above all the use of fertilizer. Hence, this research will be carried out to investigate the effects of integrated application of Urea fertilizer and Goat Manure on soil Nutrient Availability and Okra performance. Field trials were conducted with four treatments replicated three times in a Randomized Complete Block Design (RCBD). The treatments were Control (no Urea, no goat manure), 8t/ha-1 goat manure + 200kg/ha-1 urea fertilizer; 8t/ha-1 goat manure + 175kg/ha-1 urea fertilizer and 8t/ha-1 goat manure + 150kg/ha-1 urea fertilizer. Treatments were applied three weeks after planting by ring method with Urea and goat manure mixed. Soil physical and chemical properties, growth and yield parameters were evaluated. Data were analyzed using Analysis of Variance (ANOVA) and Duncan Multiple Range. 8t/ha-1 goat manure + 200kg/ha-1 urea fertilizer gave the highest plant height, leaf area as well as number of leaves than other treatment. However, the fruits weight, days of 50% flowering, number of fruit, fruits diameter and fruits length were significantly increased at 8t/ha-1 goat manure + 200kg/ha-1 urea fertilizer.
