Wheat (Triticum aestivum) and bean (Vicia faba L.) sole crops and their mixture in three planting pattern (M1: alternate-row intercrop, M2: within-row intercrop, M3: mixed intercrop) were used to investigate the amount of resource consumption in terms of PAR interception and nutrient uptake. The experiment was carried out as randomized complete block design with four replications. The results showed that intercropping systems had a significant effect on environmental resources consumption, where intercropping systems had more nutrient uptake and light interception compared to sole crops, suggesting the complementarity effect of intercropping components in resources consumption. The ability of wheat and bean was different in intercropping systems in absorbing nutrients because of their differences in root morphology and cation exchange capacity.

AbstractBread wheat (Triticum aestivum L.) is one of the most important cereal crops in Ethiopia. The productivity of wheat is markedly constrained by nutrient depletion and inadequate fertilizer application. The experiment was conducted to study the effect of nitrogen (N) and potassium (K) fertilizer rates on growth, yield, nutrient uptake and use efficiency during 2019 cropping season on Kedida Gamela Woreda, Kembata Tembaro Zone Southern Ethiopia. Factorial combinations of four rates of N (0, 23, 46 and 69 kg Nha−1) and three rates of K2O (0, 30 and 60 kg Nha−1) in the form of urea (46–0-0) and murate of potash (KCl) (0-0-60) respectively, were laid out in a randomized complete block design with three replications. The results showed that most parameters viz yield, yield components, N uptake and use efficiency revealed significant differences (P < 0.05) due to interaction effects of N and K. Fertilizer application at the rate of 46 N and 30 kg K ha−1 resulted in high grain yield of 4392 kg ha− 1 and the lowest 1041 from control. The highest agronomic efficiency of N (52.5) obtained from the application of 46 kg N ha−1. Maximum physiological efficiency of N (86.6 kg kg−1) and use efficiency of K (58.6%) was recorded from the interaction of 46 and 30 kg K ha−1. Hence, it could be concluded that applying 46 and 30 kg K ha−1was resulted in high grain yield and economic return to wheat growing farmers of the area. Yet, in order to draw sound conclusion, repeating the experiment in over seasons and locations is recommended.

Nitrogen fertilization ensures productivity and persistency of pastures, but may be expensive. Perennial forage peanut, becomes an interesting alternative for N supply. Little is known about its use under grazing. The objective of this study was to evaluate regrowth process of forage peanut using an experimental protocol analogous to tropical forage grasses under rotational grazing. Treatments corresponded to two pre- (95% and maximum canopy light interception – LI95% and LIMax) and two post-grazing (post-grazing heights of 40 and 60% of pre-grazing height) conditions, in a 2x2 factorial arrangement in a randomized complete block design (n = 4). Targets of LI pre-grazing affected  pre-grazing height and LI post-grazing. The residual sward LAI did not vary, resulting in similar grazing interval. Greater rates and total herbage accumulation were recorded for LIMax target, consequence of the greater accumulation of stolons at the lower strata of the swards. Greater percentage of leaflets was recorded for the LI95% target. Given the stoloniferous growth habit of forage peanut, stolon accumulation in the lower strata of the sward do not represent a limitation to leaf accumulation and morphological composition. The greater pre-grazing sward height associated with the LIMax target facilitate herbage prehension and intake, further investigation is needed.

A field experiment was carried out in Ramhormoz, Iran during the 2008-2009 growing season to investigate the effects of different planting pattern of intercropping on environmental resource consumption and weed biomass. A randomized complete block design (RCBD) with three replications was employed to compare the treatments. Treatments included maize sole crop (M), cow pea sole crop (C), within row intercropping (I1), row intercropping (I2) and mix cropping (I3). The density of intercropping was according to replacement design (one maize replaced by three cow pea plants). The results showed that environmental resource consumption was significantly (P?0.05) affected by cropping system, where PAR interception, moisture and nutrients uptake were higher in intercropping systems compared to sole crop systems. Regarding to weed control, intercrops were more effective than sole crops and it was related to lower availability of environmental resources for weeds in intercropping systems.

An experiment was conducted to study the yield response and nutrient uptake of rice (BRRI dhan30) to reduced rates of N, P and K from the recommended fertilizer doses (RFD). The experiment was laid out in a randomized complete block design with four replicates. There were ten treatments viz. T1 (control), T2 (RFD), T3 (RFD - 20% N), T4 (RFD - 40% N), T5 (RFD - 20% P), T6 (FRD - 40% P), T7 (RFD - 20% K), T8 (RFD - 40% K), T9 (RFD - 20% NPK) and T10 (RFD - 40% NPK). The recommended fertilizer doses of the crop were 100 kg N, 20 kg P, 40 kg K, 20 kg S and 3 kg Zn ha-1. The highest grain yield (5.10 t ha-1) and straw yield (7.02 t ha-1) were obtained by applying recommended doses of fertilizers which were insignificantly different from those observed in the treatments where N, P and K were reduced at the rate of 20% from the recommended doses. Similar results were also found in case of P, K and S content and uptake by rice plant, while the variation for N was found significant. Overall results indicated that 20% reduction of either N or P or K from the recommended doses would not significantly affect the yield of rice.

Abstract Indonesia has many types of carbohydrate sources. Tacca (Tacca leontopetaloides) has potential as a source of the functional food industry, especially maltotriose and maltotetraose production. Tacca grows well in an open or a shaded area on sandy soil-mineral, soil pH is slightly alkaline, with very low to low Cation Exchange Capacity. Malapari (Pongamia pinnata) is a biofuel-producing plant with a natural distribution on coastal land. Planting combination between malapari as an energy-producing plant and tacca as a food source has never existed. So, it needs to be incentives in developing agroforestry that can provide intermediate results for farmers. The requirement of good quality tacca seedlings is a crucial factor in supporting food security. This study aimed to determine the effect of the types of tacca seeds used on the initial growth of tacca. The study used a randomized complete block design consisting of 3 (three) treatments: a) large tubers, b) small tubers, and c) the origin of seeds. The results showed that plants from large tubers produced the highest number of shoots, height, and diameter (5.83; 27.77 cm and 0.43 cm). Five years old malapari reaches a diameter of 6.95 cm, a height of 3.89 m, and a crown width of 2.43 m.

Abstract The field-based experiment was conducted during the 2020 – 2021 cropping season to evaluate the response of two types of bean (Vicia faba L.): Luz De Otono (C1) and Aquadulce (C2 for different spray treatments namely, control (T1), 40mg IAA.L-1 (T2) and 10gm of licorice with yeast.L-1 (T3),. The treatments were assigned to experimental plots following a randomized complete block design (R.C.B.D). Each treatment replicated trice time. Means were compared based on least significant differences (LSD) at 0.05 of probability. Plant height, leaves area, chlorophyll, N and K content in leaves were recorded as parameters. Results showed that the Aquadulce variety significantly increased in most studied measurements. T3 was significant and superior compare to other treatments in plant height (68.28cm), leaves the area (51.5dcm2), chlorophyll (23.98 SPAD), N(4.623%), and K(3.120%). Results also indicated that the interaction of C2T3 had a significant increase in plant height(68.95cm), leaves the area (57.0 dcm2), chlorophyll, N(4.88%), and K(2.68%).

In severely deficit soil, lentil (Lens culinaris Medic) crop requires micronutrients for increased production. Micronutrient management is, therefore, very important for lentil productivity but mostly ignored. This study was carried out from 2014–2015 to 2016–2017 to understand the effects of zinc (Zn), boron (B), and molybdenum (Mo) on lentil productivity, nodulation, and nutrient uptake and how these elements improve soil micronutrient fertility. The experiment was laid out in randomized complete block design, and the treatments were replicated thrice. Different combinations of Zn, Mo, and B were contrasted with no application of micronutrients. The treatments were Zn alone (Zn), B alone (B), Mo alone (Mo), Zn combined with B (ZnB), Zn with Mo (ZnMo), B with Mo (BMo), and Zn combined with B and Mo (ZnBMo). Doses of Zn, B, and Mo were 3, 2, and 1 kg ha−1, respectively. In this trial, the highest average seed yield (1807 kg ha−1) and yield increment (44%) was obtained in ZnBMo combined application with macronutrients. Single, dual, and combined application of Zn, B, and Mo had significant effects on yield parameters and yield of lentil (P < 0.05). The highest nutrient uptake, maximum nodulation (63.5 plant−1), and the highest protein content (26.6%) in seed were recorded from the treatment receiving all three micronutrients. The increased lentil yield might be associated with increased nodulation and nutrient uptake by the crop under micronutrient-applied treatments. The results suggest that combination of Zn, B, and Mo could be applied for increased lentil production in micronutrient deficit soils.

The economic rate of nutrients was determined with eight different fertilizer treatment applied on T. aman rice (var. Binadhan-7) in Old Brahmaputra Floodplain Soils (AEZ-9) during 2012 and 2013 at Trisal, Mymensingh. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The treatment combinations were: T1 (N64 P14 K28 S6 Zn1), T2 (N80 P14 K28 S6 Zn1), T3 (N80 P17.5 K28 S6 Zn1), T4 (N80 P14 K35 S6 Zn1), T5 (N64 P17.5 K35 S6 Zn1), T6 (N80 P17.5 K35 S6 Zn1), T7 (N48 P10.5 K21 S4.5 Zn0.75), and T8 (control). Grain and straw yields were significantly affected by the application of fertilizers at different rates. Results revealed that the average highest grain (4.86 t ha-1) was recorded in T6 (N80 P17.5 K35 S6 Zn1) treatment and straw yield (5.34 t ha-1) was recorded in treatment T3 (N80 P17.5 K28 S6 Zn1) which is 132.54% and 86.06% respectively higher over control treatment. The second highest grain yield (4.77 t ha-1) was obtained in T3 treatment and straw (5.18 t ha-1) was recorded in T6 treatment. Average (2012 & 2013) nutrient uptake (grain and straw) was the highest in T3 treatment. Partial budget analysis demonstrated the highest net benefit of Tk. 69,673 ha-1 in T6 followed by Tk. 68,833 ha-1 in T3 and the highest MBCR (4.29) was obtained in T3 treatment. The present investigation suggests that treatment T3 (N80 P18 K28 S6 Zn1) might be the best profitable fertilizers dose to sustain Binadhan-7 rice production in Old Brahmaputra Floodplain Soils.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22096 J.

The study aimed to determine the effects of different levels of phosphorous and zinc fertilizers on the yield and nutrient uptake of maize (Zea mays L.) The experiments were  conducted in a factorial experiment under Randomized Complete Block Design (RCBD) to determine the effect of P and Zn applications on TZL white composite improved variety            of maize. Four levels of phosphorus (0, 10, 20 and 30 kg P ha-1) and three levels of zinc (0, 5 and 10kg Zn ha-1) were applied on experimental plots of 4.5m x 5m replicated thrice.  The results shows no significant differences in both the  years however, highest mean values of 2327.5 kg ha-1  and 2191.5 kg ha-1 was recorded at 20 kg P ha-1 and 10 kg Zn ha-1 Application of P and Zn at different rates increases their uptake in the stover with highest values of 22.57 mg -1 kg  and 7.8 mg -1 kg  in 2018  at 30 kg Pha-1 and 18.40 mg -1 kg  and 5.21 mg -1 kg  at 20 kg Pha-1  in 2019. While 26.54 mg -1 kg and 21.85 mg -1 kg in 2018 at 10 kg Znha-1 and 6.76 mg -1 kg and 5.27 mg -1 kg in 2019 with 0 kg Znha-1 respectively. It is therefore recommended the best results of the application of 30kg P ha-1 and 10 kg Zn ha -1 should be adopted for optimum yield of maize.

Potassium is the key element for mungbean (Vigna radiata L.) productivity. The study was carried out to understand the effects of potassium (K) on mungbean productivity, quality, nutrient content and nutrient uptake and how this element can help to manage soil fertility.Therefore, an experiment was conducted during two consecutive years 2016 and 2017. The experiment was laid out in randomized complete block design considering six treatments with thrice replicates. The treatments were T1 = Control, T2 = 30 kg K ha-1, T3= 40 kg K ha-1, T4= 50 kg K ha-1, T5= 60 kg K ha-1 and T6= 70 kg K ha-1 along with the blanket dose of N15P20S10Zn2B1.5 kg ha-1. Results revealed that application of different levels of potassium showed significant effects on the plant height, number of pods per plant, number of seeds per pod and thousand seed weight which were influenced to obtain higher yield of mungbean. The highest average seed yield (1476 kg ha-1) and highest yield increment (39.5%) of mungbean were produced from the treatment T5. Most of the cases the highest nutrient (N, P, K, S, Zn and B) content was obtained in T5 treatment.The highest K uptake by mungbean, maximum nodulation, the highest protein content in seed and maximum apparent K recovery efficiency (54.8%) were, however, recorded from the treatment receiving of 60kg K ha-1. It was concluded that proper use of K with other nutrients facilitated to improve the productivity and quality of mungbean and also K played a significant role in maintaining soil fertility.
