Abstract

Rice straw is an abundant resource that was still seen as a waste in intensive rice cultivation. Rice straw is said to be a resource because it can be used as organic fertilizer (compost) and contains nutrients that were beneficial for crop growth and soil fertility. The fact in the field was still found that rice straw was wasted, one of which was burned. A study was conducted through a method of observation and survey involving rice paddy farmers in 3 sub-districts in the district of Klungkung, namely Banjarangkan, Klungkung and Dawan. The aim of the research was to know the production of rice straw waste and the potential of wasted organic fertilizer in intensive rice cultivation. Based on the results obtained the production of dried straw waste in each harvest about 10.21 tons/ha.  Farmers do not utilize rice straw as compost by reason, not knowing how to composting. There were 30.34% of farmers who burn straw because based on the knowledge gained burn is an easy way to restore rice straw to the ground. The impact of burning rice straw was around 5,887,086 - 7,888.7 tons of organic fertilizer wasted.

Abstract

Seedling performance is a prerequisite for successful palm oil cultivation. Determining the growth of seedlings in addition to genetic factors can also be influenced by the provision of nutrients at the beginning of growth. This research was conducted with the aim to get the best combination of cow manure with urea and NPK on the growth of oil palm seedlings in pre-nursery. This experiment used a factorial design, consisting of a single factor arranged in a completely randomized design (CRD), which is a combined application of cow manure, urea fertilizer and NPK fertilizer consisting of 4 combination levels (0.4 g urea + 0.4 g NPK; 0.2 g urea + cow manure fertilizer, 0.2 g NPK + cow manure fertilizer, and 65 g cow manure fertilizer). Research data was analyzed using Analysis of Variance (ANOVA) at 5% significance level. The results showed that administration of a combination of 0.2 g urea + 40 g cow manure produced the best growth of oil palm seedlings, although it had the same effect as a combination of 0.4 g NPK fertilizer + 50 g cow manure, whereas the combination treatment of 0.4 g urea + 0.4 g NPK fertilizer and 65 g cow manure treatment resulted in lower growth of oil palm seedlings.DOI: 10.37637/ab.v3i1.419

Abstract

The study was conducted in 2019/2020 for two years in Habru, Kobo, and Dawa Chefa districts of the Eastern Amhara with the main objectives of evaluating and validating the productivity, evaluating economic feasibility and selecting the best performing sowing method and seed rate of tef technologies under farmers condition. The districts were selected based on their representativeness for the growth of tef. Three treatments were used for the study namely row planting with 5kg.ha-1, row planting with 10kg.ha-1, and hand broadcasting methods. Tef (Zoble variety) was used for the study purpose. Based on the data obtained, the highest yield was obtained from the hand broadcasting (25kg.ha-1) and the lowest yield was from the row planting (5kg.ha-1). The mean yield of tef from the hand broadcasting (25kg.ha-1) was 16.5% higher than the row planting (5kg.ha-1). Similarly, the labor utilization has increased from hand broadcasting 25kg.ha-1to row planting of (5kg.ha-1) and 10kg.ha-1. The labor cost for row plantings of tef was also higher, whereas the hand broadcasting (25kg.ha-1) consumed the least labor. This study therefore has proved that hand broadcasting is both high yielder and economically feasible in the Eastern Amhara. In addition to this, the study suggests that there should be additional seed rate study on broadcasting In order to gain optimum tef yield with feasible economic advantage.

Abstract

This study was proposed to analyze farmers’ varietal perception of bread wheat. From Meket district, four kebeles were randomly selected to achieve the above objective. The study uses cross-sectional data collected from randomly selected 214 farming households through an interview schedule. Fourteen Likert items were included in two categories as advantages and disadvantages of the technology.  Five-point Likert scale was used to analyze varietal perceptions. One-way ANOVA was employed for testing the overall mean differences among bread wheat technology adoption categories. In addition, the Relative Importance Index (RII) was used to analyze item relative importance. Farmers supported improved bread wheat varieties for specific attributes such as, high marketability, early maturity, better grain yield, grain color, food quality, and storability were found to be taking the average score of 4.43, 4.43, 4.33, 4.01, 3.85, 3.45, and 3.26, respectively. Whereas, improved bread wheat varieties were perceived to be unsuitable for shattering problems, straw quality, and low yield performances in poor soil types. Therefore, breeding objectives should be oriented towards improving bread wheat variety traits related to shattering and straw quality. Limitation of labor is one of the major reasons for the low adoption rate of row planting. Hence, machinery should be carried out to promote row planting of bread wheat. Moreover, the study indicates the need to entertain farmers’ perception of bread wheat technologies for creating wider adoption.
