A total of five separate field trials were conducted at farm farmers’ field in Sylhet area during three consecutive crops seasons of 2014-15, 2015-16 and 2016-17, respectively to evaluate the yield performance of improved varieties with the existing cultivars of five vegetables at farmers' field. Each experiment was laid out in randomized complete block design with six dispersed replications. The unit plot size was 5m x 8m.The results showed that improved variety of tomato (var. BARI Tomato-14) produced higher average fruit (55.60 t ha-1) yield with the yield increase of 16.93% over control. In case of country bean, the local variety Goalgadda performed better and produced higher green pod yield (14.31 t ha-1) compared to that of BARI Sheem-6. The brinjal variety BARI Bt Begun-2 was the best yielder with an average fruit yield of 25.62 t ha-1 i.e. 107.62% increase over non-Bt as check. In case of yield trial with Capsicum, locally grown cultivar California Wonder performed better and produced comparatively higher yield (14.02 t ha-1) than var. BARI Mistimorich-1. In case of summer hyacinth bean viz., BARI Sheem-7 gave higher pod yield of 14.96 t ha-1 compared to that of the check variety (11.41 t ha-1) in researcher-managed trial.SAARC J.

Recognition of high yielding and nitrogen (N) fixing groundnut genotypes and desegregating them in the cereal-based cropping systems common in savannah regions will enhance food security and reduce the need for high N fertilizers hence, minimize the high cost and associated environmental consequences. Field trials were conducted during the 2015 growing season at the Research Farms of Bayero University Kano (BUK) and Institute for Agricultural Research (IAR), Ahmadu Bello University, Samaru-Zaria to assess the yield potential and Biolog- ical N fixation in 15 groundnut genotypes (ICG 4729, ICGV-IS 07823, ICGV-IS 07893, ICGV-IS 07908, ICGV- SM 07539, ICGV- SM 07599, ICGV-IS 09926, ICGV-IS 09932, ICGV-IS 09992, ICGV-IS 09994, SAMNUT-21, SAMNUT-22, SAMNUT-25, KAMPALA and KWANKWAS). The groundnut genotypes and reference Maize crop (SAMMAZ 29) were planted in a randomized complete block design in three replications. N difference method was used to estimate the amount of N fixed. The parameters determined were the number of nodules, nod- ule dry weight, shoot and root dry weights, pod, and haulm yield as well as N fixation. The nodule dry weight, BNF, haulm, and pod yield were statistically significant (P<0.01) concerning genotype and location. Similarly, their interac- tion effect was also highly significant. ICGV-IS 09926 recorded the highest nod- ule dry weight of 2.07mg /plant across the locations while ICGV-IS 09932 had the highest BNF value of 140.27Kg/ha. Additionally, KAMPALA had the high- est haulm yield, while ICGV-IS 07893 had the highest pod yield across the loca- tions with a significant interaction effect. The result shows that ICGV-IS 07893 and ICGV-IS 09932, as well as ICGV-IS 09994 and SAMNUT – 22, were the best genotypes concerning BNF, haulm and pod yield in the Northern Guinea and Sudan Savannahs of Nigeria respectively with the potential for a corresponding beneficial effect.

from International Centre for Agricultural Research in the Dry Areas (ICARDA) including some advanced lines from Bangladesh Institute of Nuclear Agriculture in 2006. During Preliminary Yield Trial, the genotype LG-208 produced 18.62% and 29.47% higher seed yield than the check variety BARI Masur-5 at Ishurdi and Magura respectively. Through advanced yield trials, regional yield trials, on-station and on-farm trials from 2010-11 to 2015-16, it was found that exotic germplasm LG-208 showed better performance than check (BARI Masur-5). Genotype LG-208 had significantly highest seed setting and harvest index under 20% polyethylene glycol (PEG) induced drought and considered as the drought tolerant which showed similar performance with field trials in drought-prone areas (Chapainawabganj and Rajshahi). Based on the superior performance of exotic germplasm LG-208 line, BINA has decided with the National Seed Board (NSB) of Bangladesh to register this line as a high yielding drought tolerant lentil variety, named as Binamasur-10 in 2016.

Resistance Performance

Resistance performance of six groundnut varieties to Soybean Pod Borer (Etiella zinckenella Treitschke) at high and low elevation in Bengkulu.  Soybean pod borer (SPB), Etiella zinckenella Treitschke, often caused serious pod damage and reduced pod yield in several groundnut central in Bengkulu.  Field trials were conducted in two locations, Air Dingin (Rejang Lebong, 900 m asl.) and Kuro Tidur (Bengkulu Utara, 200 m asl.) to evaluate resistance performance of groundnut varieties to SPB. Six varieties,  Jerapah, Kacil, Bison, Pather, Singa dan Singa, were grown in Air Dingin.  Five varieties ( as above but minus Sima) were grown in Kuro Tidur. Susceptible local variety was used as control. Varieties were arranged in plots in randomized complete block design (RCBD) replicated three times,  in 3 m x 5 m plots and 20 cm x 30 cm planting space. Dolomite was applied at doses of 0.333 ton ha-1 in Air Dingin and 3 ton ha-1 in Kuro Tidur.  Plants were fertilized with N (Urea) - P (TSP) - K (KCl) at the nationally recommended doses (70 - 125 - 70 kg ha-1).  Damaged pods and larval density were observed three times at 63, 77 and 93 day after sowing (SAW).  Undamaged pods was weighted at harvest.  Data were analyzed with analysis of variance and LSD to separate varietal means.  The results revealed that the numbers and percetages of damaged pods incresed with plant age.  Four groundnut varieties (Kancil, Panther, Singa and Sima) suffered significantly less pod damage than local variety and the other two (Jerapah and Bison), and therefore they are more resistance than the last three. Regardless of varieties, pod damage was significantly higher in Kuro Tidur than that in Air Dingin.  The weight of undamage pods of  resistance varieties was significantly higher than that of local, but was not significantly difference from that of Bison and Jerapah, in Air Dingin. In contrast, there was no significant different undamage pod weight between all varieties in Kuro Tidur.

The effect of fungicides on potato yields in separate early blight and late blight trials during the 1996 to 2005 growing seasons at the INTA Balcarce experimental station was determined. Potato cultivars Pampeana INTA were used for early blight trials while Kennebec ones were used for late blight trials. A randomized complete block design with four replications was used in all trials. The fungicides Folicur 25EC at 0.5 liter/ha and Brestan 60WP at 0.5 kg/ha were tested in early blight trials while Dithane M80WP at 2.5 kg/ha and Ridomil Gold 68WP at 1.25 kg/ha were tested in late blight trials. Early blight infections were rated using a 0 to 50 a rating scale. Late blight severity was rated using a disease index of 0 to 5. Potatoes were graded into two categories, marketable (> 60 g) and undersize tuber “seeds” (< 60 g), and then weighed. Data was subjected to analysis of variance. Early and late blight symptoms were present every season. In early blight trials, the efficacy of the systemic fungicide Folicur 25EC was greater than that of the non-systemic Brestan 60WP. The average yield increase due to fungicide treatment during the ten-year period was 22.4% for marketable and 17.9% for total yield. In late blight trials the efficacies of Dithane M80WP and Ridomil Gold 68WP were similar. The average yield increase due to fungicide treatment during the study was 41.23% for marketable and 33.85% for total yield. Accepted for publication 23 October 2006. Published 2 February 2007.

Abstract Manganese is an essential plant micronutrient and has many functions in the plant. Deficient levels of manganese in the plant result in reduced crop yields. This study was conducted to determine the effects of foliar application of manganese salt of ethylenediamine tetra-acetate (MnEDTA) and the timing of application of the MnEDTA to the peanut (Arachis hypogaea L.) plant on crop grade, pod yield, and value. Field trials were conducted in Virginia during 1990 and 1991 to determine the optimum amounts of MnEDTA needed for production of the virginia-type peanut. The predominant soil type was Yemassee fine sandy loam (fine-loamy, siliceous, thermic Aeric Achroquults). Manganese treatments enhanced fancy pod development and increased the percentage of extra large kernels for NC-V 11 and NC7. Other grade factors were not influenced. Average pod yield increases over the control were 25 and 109% for NC-V 11 in two tests during 1990. In 1991 average pod yield increase for NC-V 11 and NC 7 above the control were 65 and 103%, respectively. Crop values paralleled the pod yield data in comparison to the control and standard treatments. MnEDTA treatments were comparable to the standard treatments especially at the higher rates. Amounts of Mn, as MnEDTA, needed for foliar application to peanut were 0.3 to 0.6 kg ha-1 per application. Results show that early initial application was needed (4 to 6 wk after planting) with at least three applications applied at 2-wk intervals.

Breeding for high yielding rice varieties with VVEM (&lt;90 days after sowing/ das) is considered important to increase cropping indexes in the fully irrigated farm lands. This research was aimed to evaluate the yield potential of 200 promising VVE and VE maturing rice lines. A total of 200 VVE and VE maturing rice lines and five check varieties (Ciherang, Dodokan, Inpari 1, Inpari 13, Silugonggo) were evaluated in Preliminary Yield Trial (PYT) at Sukamandi Experimental Farm using augmented design, during the dry season of 2012. The 17 lines selected from PYT along with three check varieties (Silugonggo, Inpari 13, Ciherang) were further evaluated in Advanced Yield Trial (AYT) using randomized complete block design at Sukamandi, Kuningan, Magelang and Klaten, during wet season of 2012. Of the 200 lines tested in PYT, three lines yielded significantly higher than the best check variety (Inpari 1) and 2 lines did equal to Inpari 1. A total of 155 lines were VVE (&lt;90 das), and 45 lines were VE maturing (91-104 das). Based on yield per day, 17 lines were selected to be evaluated in AYT in WS 2012. Based on combined analyses from four locations of AYT, seven lines produced grain yield/ha and grain yield/day higher than did the best check Silugonggo (5.51 t/ha and 51.7 kg/day); there were14 lines did better than Ciherang (5.07 t/ha; 41.9 kg/day), and 13 lines yielded better than did Inpari 13 (5.27 t/ha; 46.7 kg/day). The best seven lines and lines with higher productivity per day than that of the best check, with an average yield of 5.62 t/ha up to 6.12 t/ha, with days to maturity from 87 up to 94 das, were ready to be evaluated in Multi Locational Yield Trial to meet the requirement for the release of new variety.

Field trials were conducted at the Fadama Teaching and Research farm Jega, Kebbi state University of Science and Technology Aliero, during the 2017 and 2018 dry seasons, to study the Yield of Okra (Abelmoschus esculentus L. Moench) Varieties as Influenced by Cow Dung and Poultry Manure Application. The treatments consisted of two (2) manure levels (Cow dung 12 t ha-1 and Poultry manure 6.6 t ha-1); each were designed to supply 120 kg N ha-1 using cow dung and poultry manure and three (3) varieties of okra namely LD88, NHAE47-4 and Dogo variety which were laid out in a Randomized Complete Block Design (RCBD) and replicated three times. The results obtained revealed that yield parameters such as Number of pods per plant (13.08 and 14.11), Mean pod weight (17.59 g and 19.31 g), Mean pod length (6.13 cm and 6.83 cm), Fresh pod weight per plant (0.19 kg and 23 kg) and Pod yield (5.65 and 6.38 t ha-1) were significantly increased when the nitrogen dose of 120 kgN ha-1 was applied using PM 6.6 t ha-1 in conjunction with NHAE47-4 in both 2017 and 2018. Mean pod diameter (cm) was statistically similar with both the application of CD 12 t ha-1 and PM 6.6 t ha-1. Significant interaction effect was observed between variety and manure on Number of pod plant-1 (13.97 and 13.43), and Pod yield (6.21 and 7.29 t ha-1) in both 2017 and 2018 while Mean pod diameter (3.42 cm) in only 2017. From the results obtained, it can be concluded that in Jega, Kebbi state of Nigeria which falls within the Sudan Savannah agro-ecological zone, NHAE47-4 okra variety yields better than Dogo and LD88. Therefore, NHAE47-4 variety in conjunction with PM 6.6t ha-1 application could be selected for increased okra production in the study area.

Field trials were conducted in the wet seasons of 1997 and 1998 at Makurdi, Otukpo and Yandev in the Southern Guinea Savanna ecological zone of Nigeria to study the responses of ten soybean genotypes to intercropping. The experiment was laid out in a randomised complete block design. The genotypes TGX 1807-19F, NCRI-Soy2, Cameroon Late and TGX 1485-1D had the highest grain yield. All the Land Equivalent Ratio (LER) values were higher than unity, indicating that there is great advantage in intercropping maize with soybean. The yield of soybean was positively correlated with the days to 50% flowering, days to maturity, plant height, pods/plant and leaf area, indicating that an improvement in any of these traits will be reflected in an increase in seed yield. There was a significant genotype × yield × location interaction for all traits. This suggests that none of these factors acted independently. Similarly, the genotype × location interaction was more important than the genotype × year interaction for seed yield, indicating that the yield response of the ten soybean genotypes varied across locations rather than across years. Therefore, using more testing sites for evaluation may be more important than the number of years.

Background: Organic production of cluster bean is to contribute to the enhancement of production sustainability along with ecology. Sustainability in organic farming must therefore be seen in a holistic sense, which includes ecological, economic and social aspects. A synergistic effectof bio fertilizer with crop increases the crop productivity and sustainability also. Bio fertilizers are low cost, effective and renewable sources of plant nutrients to supplement chemical fertilizers. Therfore to overcome the ill effect of chemical based farming, organic system is becoming the emerging need of the society.Methods: A field experiment ’’was carried out in Pusa Navbahar variety of clusterbean during summer season (February to May) of 2019 at College farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat, India. Sixteen treatments having various combinations of organic sources of nutrients (FYM, vermicompost, and neem cake), bio fertilizers (Rhizobium + PSB + KSM) along with RDF (20/40/0 kg/ha) as a control. They were replicated thrice in a randomized block design having a plot size of 3.0 m × 2.0 m with a spacing of 60 cm × 20 cm. Standard practices were followed during the entire course of the investigation.Result: It showed highly significant differences among different treatments for majority of the growth and yield attributing traits, but treatment T6 (75% N through FYM + Rhizobium + PSB + KSM) was rated as the best treatment for characters like days taken for germination, number of root nodules per plant, plant height at 60 DAS (cm), number of pod per cluster, number of cluster per plant, green pod yield per plant (g), green pod yield per plot (kg) and green pod yield per hectare (kg) as compared to other treatment. It can be concluded that the organic nutrient management in cluster bean with the application of 75% N through FYM + Rhizobium + PSB + KSM is beneficial for obtaining a higher yield.
