AbstractThere is a research gap related to the combined effects of compost produced from coffee husks and inorganic nitrogen fertilizer (urea). The objective of this study was to evaluate the yield and yield components of wheat (Triticum aestivum L.) under the integrated application of compost and nitrogen fertilizer (urea). A pot experiment was conducted in a lath house to determine the effects of the integrated use of compost produced from coffee husks and nitrogen fertilizer (urea) on the yield and yield components of wheat. The experiment consisted of nine treatments: T1, control (untreated); T2, 5 t ha−1 (8.12 g pot−1) compost; T3, 10 t ha−1 (16.24 g pot−1) compost; T4, 0 t ha−1 compost + 50 kg ha−1 nitrogen fertilizer (NF) (0.09 g pot−1); T5, 5 t ha−1 compost + 50 kg ha−1 NF; T6, 10 t ha−1 compost + 50 kg ha−1 NF; T7, 0 t ha−1 compost + 100 kg ha−1 (0.18 g pot−1) NF; T8, 5 t ha−1 compost + 100 kg ha−1 NF; and T9, 10 t ha−1 compost + 100 kg ha−1 NF. The treatments were arranged in a completely randomized design (CRD) with three replications. The compost was prepared from coffee husks and applied in wet conditions. The findings showed that the addition of compost had little effect on wheat yield and yield components in the absence of nitrogen fertilizer (urea). However, the application of the highest amount of nitrogen fertilizer (urea), which is equivalent to the recommended field rate (100 kg ha−1) (equivalent to 0.18 g pot−1), and compost (5 t ha−1) (equivalent to 8.12 g pot−1) led to a significant (P≤0.05) increase in grain yield. Under this treatment, the grain yield was 26 g pot−1 (equivalent to 14.741 t ha−1) which is a 66.29% increase compared with the control (8.9 g pot−1 (4.969 t ha−1)); in the treatment in which only the recommended amount of nitrogen fertilizer was used (21.98 g pot−1 (12.273 t ha−1)) grain yield increased by 16.74%. Spike length and dry matter yield also significantly (P≤0.05) increased with the application of integrated compost and nitrogen fertilizer (urea). The results of this experiment revealed that compost-based soil management strategies can enhance wheat production, thereby contributing positively to the viability and benefits of agricultural production systems. However, nutrient-compost interactions should receive special attention due to the great variability in the properties of compost, which may depend on the type of organic materials used.

Yield of maize hybrids could be low when grown below optimum management practices. Use of improved varieties and optimum nitrogen fertilizer application practices are unlocking the high yielding potential of hybrids maize. With these in view, a field experiment was executed on farmers’ field to determine the effect of varieties and nitrogen fertilizer rate on yield and yield components of maize in two cropping seasons. It is laid out with randomized complete block design in factorial arrangement with three replications. Five maize varieties (BH-540, BH-543, BH-661, BH-660, and BH-140) as main factor and two levels of nitrogen (55 and 110 Kg N ha−1) as subfactor were used with one maize variety (BH-543) without fertilizer as control. Leaf area and leaf area index of maize varieties were significantly affected by application of nitrogen fertilizer rates. Interaction of maize varieties with nitrogen fertilizer rates significantly affected all yield and yield components of maize. Application of half and full recommended nitrogen fertilizer produced mean grain yield advantages of 31 and 41% over control. Therefore, application of half and full recommended nitrogen fertilizer for improved maize varieties has significantly improved grain yield and recommended for maize production in midaltitude area of western Ethiopia.

An experiment was carried out at Bangladesh Agricultural University, Mymensingh to evaluate the effect of urea super granule (USG) as a source of nitrogen on the yield and yield components of transplant Aman rice cv. BRRI dhan39, BRRI dhan46 and BINA dhan7. Five levels of N (viz., 0, 60, 120 kg ha-1 as prilled urea and 60 and 120 kg ha-1 as USG) were taken as experimental treatments. The experiment was laid out in a randomized complete block design with three replications. Plant height, effective tillers hill-1, grains panicle-1 and grain yield varied significantly due to different cultivars. All the yield and yield components except 1000-grain weight were influenced significantly by the levels of nitrogen fertilizer. The highest grain yield (4.82 t ha-1) was recorded in BINA dhan7 and the lowest one (4.30 t ha-1) was recorded in BRRI dhan39. Nitrogen @ 120 kg ha-1 as USG performed the best among the treatments in respect of yield and yield components of rice. The highest grain yield (5.46t ha-1) was obtained from BINA dhan7 with 120 kg N ha-1 as USG which was statistically identical with 60 kg N ha-1 as USG. A considerable amount (31.25%) of prilled urea (PU) nitrogen could be saved by using USG. It may be concluded that USG could be used as N management to achieve better nitrogen use efficiency in reducing N loss than the PU.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19095 Progress.

An experiment was conducted at Agronomy Field Laboratory of Rajshahi University to evaluate the effect of variety and weeding regime on yield and yield components of wheat. Four varieties viz. Prodip -V1, Gourab -V2, Shatabdi -V3, Bijoy -V4 and five weeding regime viz. a) No weeding -W0, b) Weed free -W1, c) One hand weeding at 20 DAS -W2, d) Two hand weeding (1st at 20 DAS and 2nd at 42 DAS) -W3 and e) Lintur 70 WG @ 250 g ha-1 -W4 were included as treatments in the experiment. The experiment was laid out in a Split-plot Design with three replications. The results revealed that Prodip produced the highest grain yield (5.33 t ha-1) followed by Gourab (4.85 t ha-1), while the lowest grain yield (3.98 t ha-1) was obtained from Shatabdi. The highest grain yield (5.09 t ha-1) was obtained in Weed free (W1) followed by W3 (Two hand weeding) (4.89 t ha-1) and the lowest grain yield (4.13 t ha-1) was obtained in no weeding treatment (W0). The highest grain yield (5.64 t ha-1) was obtained from the combination of Prodip and weed free treatment (V1W1) and the lowest (3.57 t ha-1) was obtained from the combination between Shatabdi and no weeding treatment (V4W0).DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14800 J.
