Abstract

The demand of organic cultivation of plants is increasing and soil application of organic fertilizer reduces the hazardous usage of inorganic fertilizer and Humic acid is an organic compound derived from plant and animal residues and microbial cells with long-term physical, chemical, and biological processes. In addition, ultivation of soybean in Kurdistan region is not in a wide value therefore, the objective of this study was to determine the impact of soil application of different rates of Humic acid as an organic fertilizer on the growth characteristic of soybean cultivated and determining the best cultivation period for soybean growth. The experiment was conducted in randomized complete block design with two factor treatments and 3 replication, the first factor was one dose soil application of four different  Humic Acid rates (HAR) which were (0 (control), 2,4,6,8 g/L) and two cultivation period (CP) which were cultivation Period 1 (CP1) on 15 May 2022 and cultivation Period 2 (CP2) on 1st of  June 2022. Observations were made against the growth parameters of plant height number of branches, leaf area, root length, shoot fresh weight and shoot dry weight. The  effect of soil application of humic acid rates (HAR) was highly  significant on the plant height and root length and significant on the No. of branches, shoot fresh and dry weight. While, cultivation period insignificantly affected the growth parameter except for leaf area.  was significant. The maximum plant height, number of branches, leaf area, root length, shoot fresh and dry weight were observed with soil application of 8 g/L of humic acid  which were (82.83 (cm), 23.33, 8815 (mm2), 68.83 (cm), 503.33 (g) and 190.00 (g) respectively. The highest plant height (72 cm), number of branches (18.87), leaf area (7714 mm2), root length (57.13 g), shoot fresh (263.67 g) and dry weight  (102.93 g) were observed when the planted cultivated in 1st   period (CP1) compared to CP2.

Abstract

Low soil fertility is a limiting factor for crop production in general. Increasing the yield of garlic with balanced fertilization is an important key identified, also the right type and dose of fertilization is also a major problem. The purpose of this study was to determine the effect of inorganic fertilizer (nitrogen) and chicken manure doses on the growth and yield of garlic. The experimental design used in this research was a completely randomized design. The first factor was chicken manure, which consists of two levels, i.e., without chicken manure and 40 t/ha of chicken manure. The second factor was the dosage of N fertilizer which consists of twenty levels, ie, no fertilizer, urea with a dose of 50, 100, 150, 200, 250, 300, 350, 400. 450, 500 kg/ha, ZA with a dose of 50, 100, 150, 200, 250, 300, 350, 400. 450, 500 kg/ha. The results showed that the combination of urea fertilizer 500 kg/ha and chicken manure 40 tons/ha gave the highest yield of stored dry tubers and was significantly higher than control plots and other treatment combinations. Likewise other growth and yield parameters increased progressively. Therefore, it can be concluded that to increase the yield of garlic in the study area, 500 kg/ha of urea fertilizer and 40 tons/ha of chicken manure are needed. The recommendation is that on Andisol soil for garlic cultivation, it is better to use a combination of 500 kg/ha urea and 40 t/ha chicken manure.

Abstract

Climate extreme is one of Zambia's most pressing issues impacting socio-economic development. This paper assessed the impact of adaptation to climate extremes, as well as the effectiveness of adaptation strategies to mitigate the negative impact on food production. A total of 270 smallholder farmers were sampled. Descriptive analysis, and, the   endogenous switching regression model were applied. According to the study's findings, adaptors and non-adaptors have a number of different characteristics. Furthermore, based on the estimates of the endogenous switching regression model, radio ownership, seed quantity and farming experience, had a positive relationship with adaptation. Also, the results showed that adaptors are ‘better producers’ than the non-adaptors. In light of the findings, some policy recommendations were made. When drafting policies (a) it is necessary to draw on the expertise and experience of farmers and local institutions, (b) consider the assets of the farmers and (c) enhance farmers’ access to more affordable agricultural inputs.
