Wheat (Triticum aestivum L.) is the uppermost cereal grain crop considered as a major stable food for the Egyptian people. Field experiments were conducted during two consecutive winter seasons of 2017-18 and 2018-19 to study the effect of two planting dates (PD) (20th of November and 20th of December) under four different planting methods (PM) (bed broadcast, flat broadcast, drill at 15 cm, and drill at 25 cm apart rows) on the productivity and water relations of wheat genotype (Egypt 1). The study is intended to assess the water relations for wheat planting dates and planting methods and determine the role of late planting date and planting methods on wheat productivity. Results showed that the values of grain yields and some attributed yields were highly significantly affected by planting dates and methods in the two growing seasons. Planting wheat at the optimal date (20th November) was better than sowing at the late date (20th December) for all values obtained from the studied parameters in both seasons of the study. The bed broadcast planting method gave the highest mean values for all studied parameters except the plant height which was recorded with drilling seeds at a 15 cm planting method in the two growing seasons. The highest values of water applied were recorded with the first date under the borders planting method (PD1M2), while the lowest of Aw recorded was from beds planting method with the second date. The highest mean values for WP were recorded with the bed broadcast planting method.

The Relationship

Crop rotations involving perennial alfalfa (Medicago sativa L.) present the unique problem of terminating the alfalfa stand. Intensive tillage currently used to terminate alfalfa increases the risk of soil erosion and reduces many of the rotational benefits from alfalfa. Inadequate alfalfa termination results in severe competition to the following crop by surviving alfalfa plants. Field experiments were conducted in Manitoba between 1991 and 1993 with the following objectives: 1) to investigate no-till vs. tillage management systems for successful alfalfa termination, 2) to compare fall vs. spring alfalfa termination, 3) to compare the performance of barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) seeded into alfalfa residue, and 4) to determine the relationship between alfalfa escapes and grain yield. Fall termination produced higher grain yields than spring termination, however this advantage was only achieved with the better termination treatments capable of lowering alfalfa regrowth below a critical level. The best herbicide treatment tested here was glyphosate at 1.78 kg a.i. ha−1. Successful treatments would have to reduce residual alfalfa basal crown area (a measure of alfalfa regrowth potential) after cereal grain harvest to below 2%. Alfalfa escapes reduced yield of following wheat and barley crops similarly (P > 0.05). When alfalfa termination treatment method allowed some regrowth, in-crop herbicide treatments significantly reduced alfalfa basal crown area. Results of this study indicate that it is feasible to terminate alfalfa with herbicides in the absence of tillage, however an overall cropping strategy, including adequate consideration of weeds present in alfalfa fields at time of termination, must be considered.

Field experiments were conducted for two consecutive years during kharif and rabi season of 2015-16 and 2016-17 at Research area, Department of Agronomy, CCSHAU, Hisar to evaluate the direct and residual effect of planting methods and phosphorus levels on productivity, agro-meteorological indices, thermal and energy efficiencies in mungbean– wheat cropping system. The experiment was laid out in split plot design during kharif and in split -split plot design during Rabi with five replications at same site during both the years. Main plot treatments consisted of planting methods viz. furrow irrigated raised bed (FIRB) and conventional where as sub plot consisted of three levels of phosphorus, viz., 30, 40 and 50 kg P2O5 /ha applied to mungbean in kharif and sub -sub treatments applied to wheat in rabi were 40, 50 and 60 kg P2O5 /ha. Sowing of mungbean and wheat crops on beds i.e. furrow irrigated raised bed was superior over conventional sowing in respect of productivity. In mungbean, application of 50 kg P2O5/ha to mungbean significantly increased grain yield over 30 and 40 kg P2O5/ha, respectively but it did not differ significantly with 40 kg P2O5/ha. The residual effect of phosphorous applied to mungbean was found to be non significant on yield attributes and yield of wheat. However, direct application of phosphorous to wheat had significant effect on yield attributes and yield. The agro meteorological indices values were similar under FIRB and conventional method however, thermal and energy efficiencies were higher under FIRB planting as compared to conventional and increased with increasing levels of phosphorous.

Soybean is a major grain crop in Brazil, and yields can be considerably improved by inoculation with selected Bradyrhizobium strains. However, the incompatibility between inoculation and seed treatments with fungicides and micronutrients represents a major barrier to the achievement of high rates of biological N2 fixation. Inoculation practices that can alleviate the negative effects of agrochemicals must therefore be found and in-furrow inoculation seems to be an attractive alternative. This study reports the results of seven field experiments conducted in three growing seasons in Brazil; three in soils previously cropped with inoculated soybean (> 10(4) cells g-1 of soil of Bradyrhizobium), and four in areas where the crop was sown for the first time (< 10² cells g-1 of soil of Bradyrhizobium). The compatibility with fungicides and micronutrients was compared in seeds inoculated with peat or liquid inoculants, or treated with different doses of liquid inoculant in-furrow. In areas with established Bradyrhizobium populations, seed-applied agrochemicals did generally not affect nodulation, but also did not increase yields, while inoculation always increased N grain accumulation or yield, and N fertilizer decreased both nodulation and yield. Where soybean was sown for the first time, the seed treatment with agrochemicals affected nodulation when applied together with peat or liquid inoculant. In-furrow inoculation alleviated the effects of seed treatment with agrochemicals; the best performance was achieved with high Bradyrhizobium cell concentrations, with up to 2.5 million cells seed-1.

Field experiments were conducted at Punjab Agricultural University, Ludhiana (Punjab) to study the effect of different agronomic aspects of bed planting on growth and yield of rice during Kharif seasons of 2012 and 2013. The 30 days old seedlings of both rice varieties PR-118 (V1) and PR-116 (V2) were transplanted on 15th June (D1), 30th June (D2) and 15th July (D3). The two rice varieties were transplanted under bed planting (M1) and conventional planting (M2) methods respectively. The results showed that growth parameters like number of tillers per plant, dry weight per plant leaf area index (LAI) and plant height were significantly higher in bed planting than conventional method. In bed planting method, grain yield of rice (48.82q/h) was found to be more than the conventional method (35.74 q/h) during 2012.Varieties PR-118 yielded 47.61q/h more than PR-116 (39.97 q/h) in bed planting. Yield contributing characters like number of effective tillers, number of grains per plant and 1000-grain weight of rice were more in bed planting than conventional method. Harvest index and biological yield was also found to be more in bed planting method than conventional planting. Rice transplanted on 15th June yielded (50.15q/h) more than 30th June (41.45q/h) and 15th July (35.27q/h). Similar results were found in Kharif 2013. Interaction between dates of transplanting and varieties and between varieties and planting methods were found significant.

Field experiments to identify suitable planting method under potato + maize system in the  high hill (2200 m) of eastern Nepal Sindhuwa, Dhankuta, was conducted during 2000 and  2001 seasons for the potato variety Hale and maize variety Ganesh 1. Of the different  planting methods tested, significantly the highest yield of potato (15.5 t/ha) was recorded  from the alternate row planting followed by recommended practice and flat row planting.  Early emergence (by 7-12 days) was in farmers' practice, whereas uniform plants (1-5  scale) observed in flat row and double row planting. Maize did not follow this trend.  Double row and farmer's practice favored good ground coverage (80-95%) by potato  plants, which attained height from 49.8cm (farmer's practice) to 56.8 cm (flat row).  Number of main stems/plant was higher in all treatments, except farmer's practice. Similar  trend was followed in tuber numbers. Maturity of crops did not depend on planting  methods. Final stand of potato ranged between 46.9 (alternate row) and 68.6 thousand/ha  (farmer's practice). Late blight and bacterial wilt infection was higher in the farmers'  practice. The height of maize plants was significantly differed between sole cropping (220  cm), which yielded higher followed by alternate row (183 cm) and flat row plantings.  Gross income from maize and potato was higher in flat row planting. The data revealed that  alternate row and flat row planting methods were superior over the common farmers'  practice and the recommended practice, so the identified planting methods were  recommended.Nepal Agric.

Field experiments were conducted in Prince Edward Island to determine the effects of MnSO4 H2O applied as a foliar spray and to the soil and the effects of chelated Mn applied as a foliar spray and limestone applications on Mn concentration and yields of alfalfa (Medicago sativa, L.), timothy (Phleum pratense L.), wheat (Triticum aestivum L.) and oats (Avena sativa L.). The Mn concentration in forages and cereal grain was not affected by method of application. Soil-applied Mn at 5 and 10 kg ha−1 was generally ineffective in increasing tissue Mn concentration. The second cut of alfalfa and timothy contained more Mn than the first cut. Yields of forages and cereals were not affected by Mn applications. Manganese concentrations as low as 29–31 μg g−1 in forages and 22 μg g−1 in cereals were not related to Mn deficiency. In spite of some foliage burning at the 2 kg Mn ha−1 foliar application, no yield reductions were found on any of the crops investigated. Applications of limestone to raise soil pH to 6.6–6.9 decreased tissue Mn in forages and cereal grain. The sharpest decreases occurred in timothy and alfalfa but did not result in low enough tissue Mn to cause Mn deficiency. Key words: Tissue Mn, soil-applied Mn, foliar-applied Mn, soil pH

Field experiments were carried between May and July 2014 to investigate the effects of three land preparation methods (flat surface, raised beds and ridges) on growth, yield and proximate composition of groundnut. The plots layout followed complete randomized block design with three replications. The results showed that growth parameters such as plant height, number of primary branches and leaf area were the highest in raised beds, followed by ridges and flat surface. Yield components such as number of matured pods per plant, number of seeds per plant and seed weight per plant were significantly higher in raised beds compared to other planting methods. Higher pod and seed yield were recorded under raised beds, but these were not statistically different from those of ridges. Regardless of the planting method, the percentage moisture, ash, fibre crude protein, crude fat and carbohydrate had values that ranged between 11.30 ± 0.88-10.67 ± 0.61%, 2.38 ± 0.33-2.07 ± 0.20%, 4.97 ± 0.05-9.95 ± 0.19%, 23.84 ± 0.14-26.51 ± 0.20%, 44.17 ± 0.37-48.86 ± 0.47% and 5.89 ± 0.14-9.59 ± 0.19% respectively. However, raised beds planting method had a remarkable influence on ash, fiber and crude protein, but limit the fat and carbohydrates contents of the seeds when compared to other planting methods. In view of its influence on growth, yield and some aspects of proximate composition, raised beds method of planting is therefore suitable for producing Arachis hypogaea L., ‘MK 373’ cultivar of groundnut.

Smart Agriculture

Besides a proper agronomic management followed by Nepalese farmers, wheat (Triticum aestivum L.) production has been severely affected by changing climate. There are many interventions, including climate-smart practices, to cope with this situation and possibly enhance crop and soil productivity. Field experiments were set up in a randomized complete block design with six treatments (TRT) with four replications in three locations (LOC) during wheat-growing seasons in Nepal from 2014 to 2016. Treatments included (i) Controlled Practice (CP), (ii) Improved Low (IL), (iii) Improved High (IH), (iv) Climate Smart Agriculture Low (CSAL), (v) Climate Smart Agriculture Medium (CSAM), and (vi) Climate Smart Agriculture High (CSAH), whereas those LOC were Banke, Rupandehi and Morang districts. There was a significant main effect of TRT and LOC on grain yield and a significant interactionn effect of TRT × LOC on biomass yield in 2014–2015. About 55.5% additional grain yield was produced from CSAM treatment compared to CP in 2014–2015. Among locations, grain yield was the highest in Banke (3772.35 kg ha−1) followed by Rupandehi (2504.47 kg ha−1) and Morang districts (2504.47 kg ha−1). In 2015–2016, there was a significant interaction effect of TRT × LOC on grain and biomass yields. The highest grain yield was produced from CSAH treatment in Banke district in 2015–2016. Overall, grain yield and other parameters showed a better response with either of the climate-smart interventions (mostly CSAH or CSAM) despite variability in geography, climate, and other environmental factors indicating the potential of climate-smart practices to improve wheat production in southern plains of Nepal.

To produce large elephant garlic (Allium ampeloprasum L.) bulbs in the southeastern United States, stock cloves must be planted in the fall. During extremely cold winters, however, winter survival rates can be very low. A 2-year study was undertaken to examine practices to increase winter survival rates. Two clove sizes (≤20 g or >20 g), three nitrogen rates (112, 224, and 336 kg/ha), and three planting methods (flat, mulched, and hilled) were tested in a RCB design with four replications. For all planting methods, cloves were set in a shallow trench and covered with soil to ground level. This was also the flat treatment. For the mulched treatment, 7 cm of straw was spread on top. For the hilled treatment, soil was mounded 10 to 15 cm high over the ground level. Cloves were planted in early October and harvested in mid-June. Use of large planting stock cloves increased winter survival rates during the harsh winter, but had no effect during the mild winter. Both years, winter survival was reduced with the flat treatment. Yields of marketable bulbs were 4 to 5 times higher when >20 g cloves were planted than when ≤20 g cloves were used. Nitrogen rate and planting method had no effect on yields. The >20 g cloves also produced larger bulbs than the smaller cloves. Of the three planting methods, the flat treatment produced the smallest bulbs. Bulbs were much larger following the mild winter than the harsh winter.
