A field experiment was carried out during kharif 2013, 2014, 2015 and 2016 at Zonal Agricultural Research Station, V. C. Farm, Mandya to study the performance of cowpea under organic production system in red sandy loam soil. The results revealed that application of 100% N equivalent compost + recommended FYM (10 t/ha) + beejamrutha (seed treatment) + jeevamrutha (500 liter/ha) recorded significantly higher grain yield during all the years of experimentation (2056, 1987, 2108 and 2365 kg/ha, respectively) and also in their pooled data (grain yield 2129 kg/ha). This increased yield was attributed to more availability of nitrogen (289.5 kg/ha), phosphorus (40.5 kg/ha) and potassium (182.3 kg/ha) in the soil compared to other treatments. The benefit: cost ratio was higher with application of 100% N equivalent compost + jeevamrutha + beejamrutha (2.81). Soil chemical properties, viz. soil pH, organic carbon content and electric conductivity, were not influenced significantly by application of organic manures. However, there was an improvement in the soil chemical properties (289.5, 40.5 and 182.3 N, P2O5 and K2O kg/ha, respectively) compared to initial soil data (229, 19.2 and 135 NPK kg/ha).

A field experiment was carried out in Kharif 2016 on B-deficient sandy loam soil at College of Agriculture, VC Farm, Mandya to study the effect of graded levels borax (5, 10, 15 and 20 kg ha1) and gypsum (100 and 200 kg ha-1) on yield and soil chemical properties of irrigated finger millet (Eleusine corocana L.) in Southern Dry Zone of Karnataka. A significantly higher grain yield of 45.95 q ha-1 (17.56% higher than the control) and a B:C ratio of 3.06 were also recorded at T12 compared with RDF + FYM (T1). Due to application of borax and gypsum, the pH, EC, and organic carbon content in soil during flowering stage and at crop harvest were non-significant. However, at the flowering and harvest of the crop, the T4 treatment had the lowest pH (7.49 and 7.43, respectively), whereas the T12 (flowering stage) and T10 (after harvest) treatments had the highest pH (7.65 and 7.67, respectively). Higher soil NPK values were detected in all treatments at flowering stage compared to after the crop was harvested. Application of borax 10kg ha-1 + 100 kg gypsum ha-1 along with RDF and FYM had a significantly higher exchangeable calcium content after harvest (6.77 cmol kg-1) than T1 (5.23 cmol kg-1). Sulphur content in soil at flowering stage and after harvest of crop was found to be significant among the treatments due to application of different levels of  gypsum. High levels of borax applied treatments, i. e. T5 (T1+20 kg borax ha-1) and T15 (T5 + 200 kg gypsum ha-1) recorded significantly higher content of B at flowering stage (4.18 and 4.09 mg kg-1, respectively) and at harvest of crop (3.88 and 3.68 mg kg-1, respectively) when compared to T1 (1.32 and 1.16 mg kg-1, respectively). Therefore finger millet absorption of boron may be reduced by using borax with a greater dosage of gypsum (200 kg ha-1). As a result, optimising the Ca/B ratio in the soil and plant is critical for increasing irrigated finger millet yields.

This experiment was conducted using a randomized complete block design with three replications at Field Crops Research Station, Abu-Graib, Office of Agricultural Research, during 2011-2012 and 2012-2013. The results revealed significant differences among genotypes for the studied characters at both seasons. The best genetic/environmental variance ratio attained for spike length (11.90) and no. of spikes. m-2 (9.22) in the first season, and grain yield (8.82) then harvest index (4.87) in the second season. High GCV observed for grain yield (15.68), no. of spikes. m-2 (15.18) in the first season, and harvest index (16.89) and grain yield (14.22) in the second season. High heritability estimates associated with high genetic advance for no. of spikes. m-2, in the first season. While, moderate h2bs estimates associated with high GA for same trait in the second season. Expected response to selection ranged from 0.93 to 84.6, also selection index ranged from 1.23 to 106.44 for grain yield and number of spikes. m-2, respectively in the first season also the same pattern was observed for value of second season. Characteristics like no. of spikes. m-2, plant height, no. of grains. Spike-1 and grain weight showed high heritability coupled with high genetic progress. Therefore, these characters should be given top priority during selection breeding in durum wheat.

<p>An improvement in soil chemical properties and crop development with silicate application has been confirmed in several plant species. The effects of silicate application on soil chemical properties and wheat growth were investigated in the present study. The experiment was carried out in 8-L plastic pots in a greenhouse. Treatments were arranged in a randomized block design in a 3 × 5 factorial: three soils [Rhodic Acrudox (Ox1), Rhodic Hapludox (Ox2) and Arenic Hapludult (Ult)] and five silicate rates (0, 1, 2, 4 and 6 Mg ha–1 of calcium/magnesium silicate), with four replications. The plant length, number of spikes per pot, shoot dry matter and grain yield, were measured after 115 days of wheat (<em>Triticum aestivum </em>L.) growth. Changes in the soil chemical properties (pH, H+ + Al3+, Al3+, P, K, Ca, Mg, Si, Cu, Zn, Fe and Mn) were analyzed after wheat harvest. Application of calcium/magnesium silicate reduces the potential acidity (H+ + Al3+) and Al3+ phytotoxic; and increases the soil pH, available Ca, Mg and Si, cation exchange capacity (CEC) and soil base saturation. Silicate application did not affect the available P, exchangeable K and availability of micronutrients (Cu, Zn, Fe and Mn) in the three soils. The application of calcium/magnesium silicate in an acid clayey Rhodic Hapludox improves the development and yield of wheat; however, the silicate application in soil with pH higher to 5.3 and high Si availability does not affect the agronomic characteristics and grain yield of wheat.</p><p><strong> </strong></p>

A field experiment was carried out at El-Kod Agricultural Research Station, Abyan Delta, Abyan Governorate during the seasons 2014 and 2015 in soil sandy silt to assess four levels of nitrogen fertilizers (0, 55, 110 and 165 kg N/ha) utilizing urea fertilizer (46% N) on some crop characteristics and efficiency of nitrogen application on two local cultivars of sorghum (Sorghum bicolor L. Moench). Split plot design was applied in four replicates. Fertilizer levels were distributed in main plots whereas, the cultivars in subplots. The results revealed significant differences between cultivars Benny and Saif in all characteristics during the two seasons. Cultivar Benny was significantly superior to cultivar Saif in all crop characteristics, except the length of spike which was significantly superior in Saif cultivar compared to cultivar Benny in both seasons. The increase in nitrogen level led to significant increase in all parameters of crop growth under study in both seasons, where the highest dose of nitrogen (165 kg N/ha) gave highest grain yield (3013 and 3201 kg/ha) in both seasons respectively, while the efficiency of nitrogen utilization declined with increased level of nitrogen application and highest value in nitrogen efficiency (12.78 kg grain/kg N). The interaction between cultivars and nitrogen fertilizer showed significant differences in terms of all studied parameters during both seasons. The cultivar Benny responded to high level of nitrogen (165 kg N/ha) and gave high grain yield (3640 and 3305 kg/ha) in both seasons respectively. The results yielded significant effect for efficiency of nitrogen application on grain yield between the cultivars, the levels of fertilizers and their interaction in the first season whereas, no significant differences were detected in the second season.

An experiment was conducted to assess the yield and yield components of QPM genotypes to plant population under irrigated conditions in a semi arid ecology of Northern Nigeria. Field trials were conducted at the Irrigation Research Station, Institute for Agricultural Research, Kadawa (11° 39'N, 08° 20'E) and 500 m above sea level) during dry seasons 2007, 2008 and 2009 to study the effect of (Zea mays L.) genotypes (TZE-W Pop X 1368, EV-DT W99 STR and DMR-ESRW), four plant population (33333, 44444, 55555 and 66666 plants ha-1) and three irrigation scheduling (40, 60 and 80 centibars soil moisture tension) on the growth and yield of quality protein maize. A split plot design was used with combinations of genotypes and irrigation regimes assigned to the main plot and plant population assigned to the sub-plot. The treatments were replicated three times. The study revealed that genotype EV-DT W99 STR had significantly higher weight of ears per plant, cob length, cob diameter, number of rows per cob, 100 grain weight, grain yield, shelling percentage and harvest index than the other two genotypes used in the trial. Irrigating at 40 and 60 centibars significantly increased weight of ears per plant, while delayed irrigation significantly depressed total dry matter production. Based on the results obtained in this study, it can be concluded that the use of genotype EV-DT W99 STR, at 60 centibars irrigation scheduling and population of 55,555 plants ha-1 had resulted in good agro-physiological characters of QPM at Kadawa.

A field experiment was conducted at Regional Agricultural Research Station, Parwanipur in 1998/99 and 1999/00 with an aim to find out the alternate management practices to compensate the loss in the grain yield due to flood. Irrespective of the varieties and transplanting dates, age of seedlings had no effect on grain yield of rice. But transplanting dates had significant effect on grain and grain contributing characters. The yield of rice transplanted at 1 Sept was 25.6 and 37.5% less in 1998/99 and 1999/00 respectively as compared to rice grain yield of 14 July transplanting. Radha 11 registered the highest grain yield of 4086 kg ha-1 in 1999/00 and 2662 kg ha-1 in 1998/99, which was at par to the yield obtained by Sabitri at the same year. The interaction effect of the age of seedlings, transplanting dates and varieties were found significant in both the years. 25 days old seedlings transplanted on 14 July in 1999/00 of rice varieties Masuli and Radha 11, produced statistically the similar yield. Radha 11 was the best among the tested varieties. 25 days old seedlings of Masuli, Basmati, Sabitri and Radha 11 can be recommended to transplant as late as Sept 1 .Key words: Age of seedlings; Rice; Transplanting datesDOI: http://dx.doi.org/10.3126/narj.v4i0.4858Nepal Agriculture Research Journal Vol. 4&5, 2001/2002Page: 14-17Uploaded date: 7 June, 2011

The field experiment was conducted at Pulses Research Centre (PRC), Ishurdi, Pabna and Regional Agricultural Research Station (RARS), Jamalpur during rabi 2012-2013 to find out the effect of seed rate and walkway for green pea production as relay cropping with transplanted Aman rice. The experiment was based on six seed rates @ 50, 60, 70, 80, 90 and 100 kg ha-1 and two walking ways viz. 15 cm wide walkway at 2 m interval over the plot and control with three replications. A local cultivar of pea, named Natore was used in this trial. Results revealed that the treatment with 100 kg seed ha-1 gave the highest pod yield of 5.13 t ha-1 and 4.98 t ha-1 at Jamalpur and Ishurdi locations, respectively which was similar to 80 (S4) and 90 (S5) kg seed ha-1.. Walkway had no significant variation in yield and yield contributing characters but it produced the higher yield over the control. Using walkway, 100 kg seed ha-1 (S6) and 15 cm walkway at 2 m interval over the plot (W1) produced the highest pod yield of 5.14 t ha-1 and 4.95 t ha-1 and fodder yield of 6.70 t ha-1 and 6.13 t ha-1 at Jamalpur and Ishurdi locations, respectively. Maximum gross margin of Tk. 1,06,040 ha-1 and Tk. 1,02,401 ha-1 was contributed by combinations of using 100 kg seed ha-1 and 15 cm walking way but maximum benefit cost ratio (BCR) of 3.40 and 3.43 were obtained from S5×W1 combination at Jamalpur and Ishurdi locations, respectively. It is concluded that pea cultivar can be successfully cultivated for green pod production through the use of 90-100 kg ha-1 seed with walkway of 15 cm wide in the plot after 2 m intervals.
