To evaluate some agronomic properties and forage characteristics in the intercropping of barley (Hordeum vulgare L.) and vetch (Vicia ervilia L.), an experiment was conducted during 2014-2016 cropping seasons. A randomized complete block design with four replications was used. Intercropping patterns included 80% barley+ 20% vetch, 60% barley+ 40% vetch, 40% barley + 60% vetch and 20% barley + 80% vetch along with the sole culture of both crops (100% barley and100% vetch). The result showed that the highest value of plant height, grain number, thousand-grain weight, biological yield, grain yield and harvest in barley was observed from 80% barley + 20% vetch intercropping ratio, however, for vetch, it was detected from 100% vetch. Furthermore, the highest land equivalent ratio was obtained from 80% barley+ 20% vetch. Based on the results, the highest crude protein content and dry matter digestibility were observed in sole cropped vetch, whereas the highest neutral detergent fiber and acid detergent fiber were recorded in sole cropped barley. These results suggested that intercropped barley and vetch as 80% barley + 20% vetch ameliorated the grain yield and yield components, and forage quality compared to other intercropping ratios.

Abstract Foliar nitrogen (N) application is considered an important factor affecting phenology, growth, yield, and yield components of dryland wheat (Triticum aestivum L.). A field experiment was conducted to study effects of foliar N on dryland wheat (cv. Prisabk-2004) at the Agronomy Research Farm, The University of Agriculture Peshawar, Pakistan, during winter 2010-2011. The experiment was laid out in randomized complete block design using four replications. A plot size of 3 m by 4 m, having 8 rows, 4 m long and 30 cm apart was used. A total of 80 kg N ha−1 in the form of urea was applied. Out of 80 kg N ha−1, 70 kg N ha−1 was applied to the soil at sowing time, and the remaining 10 kg N ha−1 was applied in the form of foliar spray (2% N). The required foliar N was applied in various combinations (splits) at different growth stages viz. 30, 60, 90 and 120 days after emergence (DAE). Phenological development (days to anthesis and physiological maturity) was delayed, yield components and yield increased significantly (p ≤ 0.05) with foliar N over control (water spray without N). Wheat grain yield increased to the highest level (4427 kg ha−1) when 100 % foliar N was applied (no split) at 90 DAE, followed by 4050 kg ha−1 at 120 DAE, while the control (no foliar N) resulted in the lowest grain yield (2573 kg ha−1). We concluded from this study that 2 % foliar N application in a single split either at 90 or 120 DAE could improve wheat productivity under dryland condition.

 The objective of this study was to investigate the effect of some amino acids on tillering and grain yield of bread wheat cultivars. A field experiment was carried out at the agricultural experiment station, College of Agriculture Engineering Sciences, University of Baghdad during the two winter seasons, 2016-2017 and 2017-2018. Randomized Complete Block Design within split plots arrangement was used in three replicates. The experiment included two factors, the first (main plots) was the wheat cultivars (IPA 99, Buhooth 22, and Abu-Graib3) and the second (sub-plots) was foliar application three amino acids (L-Tryptophan, L-Glycine, and L-Lysine) with concentrations 50 and 100 mg L-1 and the amino acid L-Cystine at 100 and 150 mg L-1 and control treatment. The treatments of foliar application were applied during two growth stages, the first was when the main stem had three leaves (ZGS: 13) and the second was when the plant entered the flowering stage (ZGS: 60). Results showed the significant superiority of Buhooth 22 in most growth traits, which produced the highest number of tillers.m-2 (556.30 and 568.15 tillers m-2), number of spikes (476.74 and 494.19 spikes m-2), weight of 1000 grains (31.09 and 32.43 g), and grain yield (5.39 and 5.15 Mg ha-1) for the two seasons respectively. The treatment of foliar application L-Tryptophan at 50 mg L-1 was significantly superior in most traits of yield components which produced the highest values of the number of tillers (616.89 and 627.78 tillers m-2), number of spikes (477.00 and 944.67 spikes m-2), weight of 1000 grains (32.01 and 33.55g), and grain yield (5.77 and 5.33Mg ha-1) in the two seasons, respectively. The response of wheat cultivar growth and yield to amino acids differed significantly.

Although,chickpea isnitrogen fixing crop but water scarcity under rain-fed condition reduces its nodulation process severely and nutrients use efficiency too. An experiment was carried out regarding the combined effect of nipping as well as foliar applied fertilizers on yield and yield components of chickpea under rain-fed conditions. Nipping and foliar application of nutrients significantly improved number of pods plant-1, biological yield (kg ha-1), harvest index (%) and final grain yield (kg ha-1). However, non-significant influence was seen in 1000-grain weight and number of grains pod-1. Foliar application of N PK (20:20:20) @2.5 kg ha-1 × nipping was found to be the best interaction among others which significantly increased number of branches plant-1 (11.30), number of pods plant-1(115.36), plant height(59.48cm) and grain yield(2338.9 kg ha-1) as compared to the control treatment. Nipping along with foliar application of NPKcan be practiced in chickpea for higher profitability.

High Yielding Varieties

Production and productivity of green gram is governed by environmental, genotypic trait of the crop and crop management. The more specific reason for low production and productivity of pulses is the cultivation of local old varieties under marginally fertile lands and low input management conditions. Recently, high yielding varieties of green gram have been developed and evaluation of these varieties under various management conditions will be of great importance. In this view the study was conducted to investigate the growth and yield response of different green gram varieties in Kitui and Makueni counties in Kenya. Three green gram varieties (KS20, KAT 00308 and KAT 00309) were laid out in a randomized complete block design and replicated three times. The varieties differed significantly (P≤0.05) in plant height, number of effective nodules, 100-grain mass and grain yield in both sites. Variety KS20 was the tallest in both sites in all the stages while KAT00309 was the shortest. Variety (KS20) had the highest number of effective nodules in Ithookwe (11) and Kiboko (39) with the lowest were recorded for variety KAT00308. Days to 50% flowering and maturity were different between the varieties, and KS20 had the shortest where it was recorded that the periods were shorter in Kiboko by >15 days compared to Ithookwe. In both sites, the highest grain yield was recorded for KAT00309 with 2898 kg/ha and 1568 kg/ha in Kiboko and Ithookwe, respectively. There were no signficant differences on the biological yield between the varieties but the 100-grain mass differed signficantly in both sites where variety KAT00309 was the heaviest with 7.8 g and 6.9 g in Kiboko and Ithookwe, respectively. It was concluded that variety KAT00309 could lead to the highest grain yield in both Kitui and Makueni counties under water stress conditions of the two counties.

Aims: A short term field study was conducted to investigate the yield performance of selected African rice genotypes inoculated with biofertilizers.   Study Design: A randomized complete block design laid out in a split-plot arrangement was used to evaluate response of yield components and grain yield of some selected African rice genotypes will be to mycorrhizal fungi and rhizobium inoculation. Place and Duration of Study: The study was conducted at the Teaching and Research farm of the Federal university of technology, Akure Ondo state, Nigeria during the 2013 planting season. Methodology: The study was laid out in a split plot arrangement in Randomized Complete Block Design (RCBD), with mycorrhizal fungi, rhizobium inoculation and control in the main plot, while genotypes (N-U-1, N-U-8, WAB 56-104, OFADA GR and MOROBEREKAN) were in the sub-plot and treatments were replicated thrice. There were three main blocks, each block consist of 15 sub-plots with a size measurement of 2m x 1m and inter sub-plot spacing of 0.5m in between plots. A total of 50 plants were raised per sub plot. Transplanted seedlings were planted with the soil slurry containing rhizobium and mycorrhizal fungi inoculum into planting holes in the field at two seedlings per stand, according to their respective plot at a spacing of 25cm x 25cm. Yield component data collected include; number of days to 90% maturity, number of days to 50% flowering; plant height at maturity, number of primary tillers per plot, number of grains per panicle, number of panicles, number of filled and unfilled spikelet, weight of 1000 filled grains and grain yield per plot.  Results: Result showed significant (P<0.05) single and interactive effect of rhizobium and mycorrhizal fungi inoculation on rice yield and yield components. 61.4% increase in grain yield was observed in rhizobium inoculated genotypes when compared to 37.4% increase in mycorrhized genotypes and the un-inoculated control. WAB56–104 and N-U-8 had the best interactive response amongst genotypes inoculated with rhizobium while genotypes WAB56-104 and MOROBEREKAN responded better amongst mycorrhized genotypes in relation to yield components. Conclusion: The results from this study indicate that African rice genotypes differ in grain yield response and host specifity when inoculated with mycorrhizal fungi and rhizobium inoculums. However, inoculating specific African rice genotypes with mycorrhizal fungi and rhizobium can positively influence their grain yield and yield component development and this could play an important role in improving African rice productivity.

In the savanna soil of Nigeria, micronutrient deficiency was not noticed in the past but with the intensification of agriculture over the years, crop exploitation of soil available nutrients, crop removal and adverse cultural practices of farmers have led to the incidence of micronutrient deficiency with negative effect on growth, yield and quality of crops. To enhance micronutrient availability, use and use efficiency to crops, a field experiment was set up on sorghum at Samaru in the Northern Guinea Savanna of Nigeria with foliar Algifol (Alg) nutrients solution and NPK. The objectives of the studies were: To test the effectiveness of the nutrient solution and NPK on growth and yield of sorghum in the Nigeria savanna and to determine optimum rates of application of the nutrient solution on sorghum under a tropical condition. The treatments were four levels each for the nutrient solution, NPK and a combination of both as ½Alg, 1Alg, 1½Alg and 2Alg at the rate of [5:10:15:20ml) of the concentrated solution to 10 litres of water per hectare and 64:32:30 kgha-1 N, P2O5 and K2O being therecommendation for sorghum in the Northern Guinea Savanna. Data were collected on plant height, plant girth, panicle yield, grain yield and stover. The treatments were laid in a Randomized Complete Block Design (RCBD) with three replications. The results showed that plant height and girth were highly significant (P < 0.01) at 9 weeks after planting (WAP) and as well as stover. Head and grain yield were positively and highly significantly correlated (r = 0.69** and 0.62**) with dry matter yield (DMY) indicating a positive relationship amongst the plant parameters in response to treatments. Co-application of the nutrient solution with NPK had greater nutritional efficiency on sorghum in the savanna than their sole application since the nutrient solution is deficient in major plant nutrients.Keywords: Nutrient solution, northern guinea, complementary application and tropical environment.

This study was carried out at National Maize Research Program, Rampur, Chitwan, Nepal to evaluate the effect of sowing dates on growth and grain yield of maize inbred lines. Seven maize inbred lines namely NML-2, RML-17, RML-32, RML-4, RML-86, RML-95 and RML-96 were planted on three different dates i.e. September 02, September 12, September 22, 2015 during winter using randomized complete block design with two replications. The results of this study showed that the growth and yield traits were significantly affected by various planting dates. The inbred line RML-17 produced the highest grain yield where as NML-2 gave the lowest yield during winter season. The highest yield was obtained when inbred lines were planted on September 12 and the lowest yield on September 2. The planting from September 2 to September 12 increased the grain yield. The delay in planting i.e. September 22 decreased grain yield. Therefore September 12 planting was suitable for inbred lines to maximize grain yield production.
