Mung bean has become an important cash and food crop in dry land areas of Ethiopia. However, there is no sufficient research information on the nitrogen (N) and phosphorus (P) fertilizers rates for the crop in the study area. Thus, field experiment was conducted to determine the effects of N and P fertilizer rates on growth, yield components and yield of mung bean under irrigation at Nura-Era, central Ethiopia. The treatments consisted of factorial combinations of three N fertilizer rates (0, 23 and 46 kg N ha-1) in the form of Urea (46% N) and five P fertilizer rates (0, 10, 20, 30 and 40 kg P ha-1) in the form of Triple Superphosphate (20% P)  laid out in randomized complete block design (RCBD) with three replications. Result of the main effect of nitrogen rate showed significantly highest number of primary branches per plant (4.25), number of  pods per plant (17.7), and 100 seed weight (4.94 g) at 23 kg N ha-1. Similarly, the main effect of P fertilizer rate showed that the application of 40 kg P ha-1 produced significantly the highest number of primary branches per plant (4.79), highest number of pods per plant (20.85), the highest number of seeds per pod (6.24), the highest aboveground dry biomass (6838.83 kg ha-1), the highest 100 seed weight (5.21 g) and the highest harvest index (25.96%). The interaction of N and P rates showed that the combination of 23 kg N ha-1 and 40 kg P ha-1 gave the highest grain yield (1902.78 kg ha-1). Thus, the combination of 23 kg N ha-1 and 40 kg P ha-1 can be used to increase the productivity of mung bean in the study area.

Mung bean (Vigna radiata L.) is a leguminous crop with a tremendous potential in achieving food and nutritional security in Ethiopia in future. In addition, mung bean plays a major role in improving soil nitrogen content through atmospheric nitrogen fixation, thus reducing the dependance on synthetic nitrogenous fertilizers. However, its productivity is limited by inadequate plant population and NPS fertilizer rate in the study area. Hence, this study was carried out to determine the optimum plant population and NPS fertilizer rates for mung bean borda variety in Bako. The experiment comprised of factorial combinations of four different plant populations (500000, 571429, 666667, and 800000 plants ha-1) and five NPS fertilizer rates (0, 50, 100, 150 and 200 kg ha-1) and it was laid out using Randomised Complete Block Design with three replications. Results indicated that main effect of plant population and NPS fertilizer rates had significant effect on phenology, growth, yield, and yield components of mung bean, except stand count, above-ground biomass, straw and seed yield, which were affected by the main factors and their interactions. Highest nodule dry weight per plant (0.14g), number of pods per plant (4.74 g), weight of seeds per pod (10.26 g), 100-seed weight (3.61g), and harvest index (31.16%) were observed under minimum plant population (500,000 plants ha-1). Moreover, effective nodules per plant (2.28), nodule fresh weight (0.33 gm), nodule dry weight (0.141g plant-1), number of pods per plant (4.79), seeds per pod (10.78 g), 100-seed weight (3.73 g) and harvest index (32.98%) were observed under 200 kg ha-1 NPS fertilizer rate. Highest stand count per hectare (780,667 plants ha−1), above-ground biomass (4,947kg ha-1), seed yield ha-1 (1,371kg ha-1) and straw yield (3,575 kg ha-1) were recorded at higher plant population (800,000 plants ha-1) with 200kg NPS ha-1 fertilizer rate. However, higher plant population (800,000 plants ha-1) at the rate of 100 kg NPS ha-1 fertilizer produced1, 325 kg ha-1seed yield which was the highest net benefit (50,080 TB) and marginal rate of returns (5,610.8%). Therefore, application of 100 kg NPS ha-1 fertilizer rate with plant population of 800,000 plants ha-1 can be recommended for mung bean production in the study area and similar agro-ecologies. However, the current study was carried out only in one location for one cropping season, hence further studies over many seasons and across several locations are needed to have a conclusive recommendation for wide range of agro-ecologies for mung bean production.

Mung bean need phosphate in seed formation and accelerate pod maturity. In acidic soil the P element is difficult to be available because it is bound by metal metals in the soil, it is given a palm bunch ash containing a lot of organic nutrients to release P from the metal and also increase soil pH. The study aims to determine the effect of P fertilization and palm bunch ash on the growth and production of mung bean. The study was conducted on community land in Medan Selayang from October to December 2019. The study used a factorial randomized block design, with 2 factors. The first factor is P fertilizer (0; 37.5; 112.5 kg SP-36/ha). The second factor is oil palm bunch ash consisting of 0; 2; 4 t/ha. The variables observed were a number of pods, weight of 100 seeds, weight of seed per plots, weight of seed per plant. The results showed that the application of P the applications of P fertilizer 112.5 kg SP-36/ha tended to produce the highest pod number and seed weight per plot. The applications of oil palm bunch ash 2 t/ha significantly increased seed weight per plant, seed weight per plot and pod number.

Cowpea (Vigna unguiculata L. Walp) is one of the potential substitutes of soybean due to its similar nutritional content. This study aims to determine the optimum rate of N fertilizer for the production of cowpea, and to determine the effects of the interaction between N fertilizer rates and goat manure application on cowpea production. The experiment was organized in a split-plot with a complete randomized block design with three replications. The main plot was goat manure, i.e. 0 and 5 tons.ha-1; the sub-plot was nitrogen fertilizer with five rates (0, 50, 100, 150, and 200% of the recommended rate), i.e. 0, 22.5, 45, 67.5, and 90 kg N.ha-1. Application of N fertilizer reduced the 100-seed weight and slightly reduced cowpea yield and yield components. Application of goat manure increased seed dry weight per plant, number of pods per plant, dry pod weight per plant, seed dry weight per m2, productivity, 100-seed weight, and the harvest index. There was no significant interaction between goat manure and different rates of nitrogen in affecting cowpea growth.

AbstractTwo field trials were conducted on the Research Farm of the Institute of Food Security, Environmental Resources and Agricultural Research, Nigeria during the late cropping seasons (Jun.–Nov.) of 2014 and 2015 to evaluate the agronomic performance of four recently released sunflower varieties (SAMSUN-1, SMASUN-2, SAMSUN-3 and SAMSUN-4) to three fertilizer regimes: Control, Split application of 30 kg N + 28 kg P2O5 at 21 days after sowing (DAS) and at anthesis and Single application of 60 kg N and 56 kg P2O5 at 21DAS. The experiment was laid out in a randomized complete block design using a 3 × 4 factorial arrangement and replicated three times. Data were collected on phenology, plant height, seed yield and yield attributes, and quality. The varietal effect was only significant in 2015 for head weight, a number of achene per head and 100 achene weight. Application of N and P fertilizer either as split or single significantly (P ≤ 0.05; F-test) enhanced plant height at R5 and R9, 100 achene weight, achene weight per head and grain yield in both years. Single application resulted in significantly (P ≤ 0.05) higher grain yield in 2014 than the split and control and was on par with a split. Significant variety × fertilizer regime was recorded for protein content in 2014 and 2015, and oil content in 2015. Therefore, a single application of N and P fertilizers at 21 WAS is recommended for adoption in the humid tropics to enhance seed and oil production of SAMSUN-3 and SAMSUN-4.

The success of any selection process is greatly enhanced by using appropriate selection indices. The knowledge of the relationship among various traits affecting grain yield is imperative to arrive at potentially effective selection index. The study was carried out to unveil the different attributes of genetic variability, the type of interrelationships among the various traits affecting yield. Fifteen local and improved maize inbred lines were crossed to three tester varieties to develop 45 test cross progenies. The parents and crosses (63 entries in all) were evaluated in two different locations with three replications at each location using the Randomized complete block design (RCBD). Data generated was recorded for the quantitative traits evaluated and subjected to statistical analysis for estimation of various variability parameters namely GCV, PCV, heritability and genetic advance alongside computing genotypic correlation coefficients and path coefficient analysis to unveil the direct and indirect effects of the various traits studied. The analysis of variability parameters evaluated revealed the presence of significant variability for all the traits studied. Grain yield, ear length, ear height, 100-seed weight and ear diameter showed high GCV estimates, with high heritability. The genetic advance was higher for plant height, ear length, grain/row and grain yield. The genotypic correlation coefficient revealed that ear diameter, 100 seed weight, ear length, kernel rows/ear and grains/row had highest significant correlation with grain yield. The path coefficient analysis revealed that highest direct effect on grain yield was exhibited by 100 seed weight followed by grains/row, kernel rows/ear, ear length and ear diameter. Most of the traits exerted their positive indirect effects through 100 – seed weight, kernel rows/ear and grains/row. The inferences of the results of the present study and their possible implications in maize breeding have been revealed.

Field trials were conducted during 2017 and 2018 rainy season, to investigate the effect of nitrogen fertilizer rates and time of application on the growth and yield of cowpea. The treatment consisted of three levels of urea: 0, 40, 80 kg N ha-1 and the times of fertilizer application: during planting of cowpea, 2 weeks after planting, 4 weeks after planting and 6 weeks after planting; which were factorially combined to form twelve treatments and laid in Randomized Complete Block Design (RCBD). The results showed that, Nitrogen fertilizer rates and time of application had a significant increased on all the growth and yield parameters of cowpea in both years of trials. Application of 80 kg N ha-1 produced the highest number of cowpea leaves (134.45 and 139.23), number of branches (9.45 and 10.54), vine length (78.23cm and 80.12cm) and highest seed weight of 0.52 t ha-1 in both 2017 and 2018 trials. However, the control plots produced plants with the highest number of root nodules (14.78 and 12.49) in both years of cropping. Also, application of nitrogen fertilizer at two weeks after planting of cowpea produced the highest growth and seed weight of 0.68 t ha-1 in 2017 cropping; while in 2018 trial, application of nitrogen fertilizer at two weeks after cowpea planting produced seed yield of 0.69tha-1 which is statistically similar with application of nitrogen fertilizer on the fourth week after planting which produced 0.55 t ha-1 of cowpea seeds. The interaction between nitrogen fertilizer application rates and time of application did not showed any significant difference in cowpea yield and yield components in both years of cropping.

<p>The objective of this research was finding the answer to comprehend the influence of herbicide kinds, tillage methods, and interaction between them on the growth and yield of mung bean (<em>Vigna radiata</em> L). The thinking background of this research is that mung bean is not tolerant with weed competition, meanwhile herbicide that can control weed on mung bean crop hasn’t been found yet. Sometimes tillage is need to control weed, too. But the effect of tillage on increasing the yield of mung bean hasn’t been completely recognized.</p><p>The research was carried out in Karangasem village, Surakarta, in about 106 meter height sea level water, at Entisol soil. The research was designed with Randomized Completely Block Design (RCBD) that arranged according to Split Plot Design, that had 2 factors with 12 treatment combinations and every combination was replicated 4 times. The first factor was tillage method as main plot, that had 3 levels as follow: no-tillage method (P0), one time tillage method (P1), and two times tillage method (P2). The second factor was herbicide kind as sub plot, that had 4 levels as follows: control (H0), Isopropylamine Glyphosate herbicide/Roundup (H1), Oxadiazone herbicide/Ronstar 250 EC (H2), and Oxyfluorfen herbicide/Goal 2E (H3). The result was analyzed with Analysis of Variance on 1% and 5% level and then analyzed with Least Square Design (LSD) test if Anova test showed significant result.</p><p>From the result of this research, we can concluded that Roundup is able to increase total mature pods and dry seed weight of mung bean, but not significantly affecting all other research variables. Goal and Ronstar can make the plant height and fresh plant biomass of mung bean lower, and not significantly affecting total mature pods, total immature pods, total unfilled pods, dry seed weight, and 100 dry seed weight of mung bean. Meanwhile Ronstar is not significantly affecting. Goal can make the dry plant biomass of mung bean lower. The tillage method treatments and interaction between tillage method and herbicide kind treatments is not significantly affecting all studied variables.</p>

Thirty biofortified inbred lines of maize were evaluated for 11 parameters to study the genetic diversity by using D2 statistics during kharif 2017in Randomized Block Design (RBD) with three replications at Agricultural Research farm, Institute of Agricultural Sciences, BHU Varanasi. In present investigation all genotypes were grouped into ten cluster. Among the different clusters of inbred lines, the cluster II with 8 inbreds emerged as the largest cluster. The intra cluster D2 value ranged from 10.82 to 44.89. The maximum intra cluster distance was observed for cluster X (D2 = 44.89). The maximum inter cluster distance was observed between cluster V and VI (D2 = 180.90) followed by cluster V and VII (D2 = 166.10), cluster IV and V (D2 = 155.60), cluster V and VIII (D2 = 135.02) and cluster I and VI (D2 = 127.66). The maximum contribution towards divergence was due to 100 seed weight (52.18%), thus, estimates of variation in seed weight could be used as a basis for selection of distantly related parents. Highest mean value for grain yield per plant (80.8) and Zn concentration (39.53) were observed in cluster IV, while the highest mean value for 100 seed weight was found in cluster V. Therefore, these clusters prove to be of prime importance for selection of parents in hybridization programme aimed at higher yield along with enhanced grain Zn concentration.
