Soil fertility is inherently low in sub Saharan Africa. The objective of this study was therefore to determine millet yield for two varieties in each zone using organic and inorganic fertiliser in two agro-ecological zones in Mali. A two-year experiment was conducted at Agricultural Research Station of Sotuba and Cinzana in 2013 and 2014. A combination of two pearl millet varieties and four fertilizer treatments were used. The fertilizers treatments used were: T1 Control (no application); T2 MANURE of 23:10:17 (5000 kg/ha); T3 NPK of 15: 15: 15 (50 kg/ha) and T4 combination of NPK + MANURE. The experiments were conducted in a randomised complete block design (RCBD) with four replications in a plot size of 10 m x 4.2 m. The varieties evaluated at Sotuba station were Sanioni, an improved local variety and Cho, a local variety while at Cinzana station Sosat, an improved variety form IER /ICRISAT and IBV8001, and an improved variety from ICRISAT were used. At Sotuba high grain with NPK+MANURE (1948 kg ha-1) followed by NPK (1281 kg ha-1), MANURE (1130 kg ha-1)and the Control (813 kg ha-1). In 2014, the grain yield NPK+MANURE) was 1602 kg ha-1, followed by NPK (1502 kg ha-1), MANURE (1466 kg ha-1) and the control (1440 kg ha-1). The grain yield gap for the Control treatment in 2013 (813 kg ha-1) and in 2014 (1440 kg ha1) was high compared to the NPK+MANURE, MANURE and NPK treatment grain yield gap for the same years. In Cinzana In 2013, higher grain yield with the treatments of NPK+MANURE, (1440 kgha-1)> NPK (1429 kg ha-1)> MANURE (1416 kg ha-1)>Control (1276 kg ha-1) were observed . In 2014, the highest grain yield with NPK+MANURE (1915 kg ha-1) followed by NPK (1561 kg ha-1), MANURE (1523 kg ha-1 1) and Control (1121 kg ha-1). The grain yield gap for the combined NPK+MANURE treatment in 2103 (1440 kg ha-1) and in 2014 (1915 kg ha1) was high compared to the others for the fertilizer grain yield gap for both years.

The purpose of this study was to assess the variation on agro-morphological traits and grain yield. A set of 14 early maize genotypes were studied at research field of Regional Agricultural Research Station (RARS), Doti, Nepal in summer seasons of 2015 and 2016. The experiment was carried out in Randomized Complete Block Design (RCBD) with three replications in each year. The variation among genotypes was observed for grain yield and flowering. The genotype SO3TEY-PO-BM produced the highest grain yield (4.33 t/ha) in 2015 whereas Rajahar Local Variety produced the highest grain yield (2.52 t/ha) in 2016. The combined analysis over years showed that Farmer’s variety was found earlier in tasseling (36 days) and silking (39 days), followed by S97TEYGHAYB(3) in tasseling (45 days) and by S97TEYGHAYB(3) and Arun-4 in silking (48 days). EEYC1 produced the highest grain yield (3.17 t/ha), followed by COMPOL-NIBP (3.09 t/ha), SO3TEY-PO-BM (2.90 t/ha), S97TEYGHAYB(3) (2.78 t/ha) and Rajahar Local variety (2.77 t/ha), respectively. The information on variation for the agro-morphological traits among studied early maize genotypes will be helpful to plant breeders in constructing their breeding materials and implementing selection strategies.

To estimate genetic parameters and heritability in durum wheat (Triticum turgidum var. durum) genotypes, seventeen genotypes (16 exotic from ICARDA and local variety (Buhooth 7)) were included in this study. 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.

Background: Pod fly, Melanagromyza obtusa is one of the most obnoxious pest causing grain damage ranging from 10-80% with a monitory loss of US$ 256 million annually. Being an internal feeder, infested pods do not show any external symptoms of damage until the fully grown maggots chew the pod wall, leaving a thin papery membrane intact called as window, through which adults exit from the pod. Several field studies were conducted to determine the efficacy of insecticides for the control of pod fly. However, these findings did not find acceptability and led to partial success. Insecticides that should leave lesser residues and pose lesser environmental threat have become imperative. The present study aimed to evaluate the efficacy of certain new insecticide molecules against pod fly in pigeonpea ecosystem. Methods: Two field experiments were conducted at Regional Agricultural Research Station, Lam, Guntur during Kharif, 2012 and 2013 in a randomized block design (RBD) using pigeonpea cv. ICPL 85063 (Lakshmi) with 17 treatments including untreated control and 3 replications. Two sprays were given at 10 days interval starting from pod initiation stage. At maturity, number of pods showing pod fly damage were recorded and expressed as percentage. Grain yield was recorded and cost–benefit ratio was worked out. Result: Among different insecticides, thiacloprid 21.7 SC, followed by diafenthiuron 50 WP, flubendiamide 480 SC and dimethoate 30 EC were very effective against pod fly with more grain yield and registered highest incremental cost benefit ratio (ICBR). It was further suggested that effective insecticides may be alternated in order to avoid development of resistance to pod fly in pigeonpea.

The experiments were conducted on station and on farm in three districts of Wolayta and Hadiya Zones, south region, Ethiopia, to evaluate the adaptation and yield, assess farmer’s preferences of desi chick pea varieties  to this agro ecological Zones during 2004/05 Meher Season. Data on plant height, hundred seed weight, pod per plant, days to flowering, days to maturity and grain yield were recorded. Five released varieties namely worku, Akaki, Mariye, Dubie, Dz-10-11 and local checks of respective locations were planted on 4.8m2 plots at spacing of 30cm*10cm. The trials were laid in randomized complete block design with three replications. Twelve farmers from three districts at four villages’ three farmers at each village were participated in conducting on farm trials with each farmer as a replicate. There were significant differences among varieties for grain yield and some of traits.  The varieties Akaki and worku were superior yielded overall to the standard and local check across villages ’and on stations. Thus, Akaki and worku out yielded other varieties and had average yields of 1440.95 kg/ha and 1434.75kg/ha at on station and similar trends on farm. The combined statistical analysis and farmers assessments revealed Akaki and worku out yielding other varieties which were also selected by farmers and researchers as the most preferred varieties’. It is therefore recommended that worku and Akaki which had higher yields be promoted for cultivation in the selected districts of south Ethiopia.

Superiority of hybrid maize cannot be overemphasized. Different types of hybrids are developed by plant breeders to improve productivity and multi-locational evaluation of these hybrids prior to release is necessary to select the best. The objectives of this study were to identify maize hybrids with superior agronomic potentials and compare the performance of top-cross and three-way cross hybrid maize varieties for grain yield and related traits under rain-fed condition in three different locations (Abeokuta, Ibadan and Akure) of Southwest Nigeria. The study consisted of ten hybrids each of top-cross and three-way cross hybrid varieties, tested with two checks. At each location, the experiment was laid out in randomised complete block design with three replications. The results showed that effects of locations, genotypes and genotype x location interactions were highly significant (p<0.01) for all the traits evaluated. Significant differences were also revealed between the top-cross and three-way cross hybrids for all the traits evaluated except days to 50% tasseling, ear diameter and 100-grain weight. The top-cross hybrids were superior over the three-way cross hybrids for grain yield by 5.25%. The hybrids ‘M0926-7’, ‘M0926-8’, ‘M1026-11’, ‘M1026-3’, ‘M1226-2’ (top-cross hybrids), ‘M1124-24’, ‘M1124-27’, ‘M1124-31’, ‘M1227-6’ and ‘M1227-7’ (three-way cross hybrids) showed highest stable yields across the three locations.  Hybrids ‘M0926-7’ (top-cross hybrid) and ‘M1124-24’ (three-way cross hybrid) that expressed early flowering with higher grain yield are recommended for drought stress prone areas because of their abilities to tolerate drought through escape.

Field experiments were conducted during kharif 2013 and 2014 at Agricultural Research Station, Mugad, University of Agricultural Sciences (UAS), Dharwad (Karnataka), to determine the response of zinc applicationon on growth, zinc content and grain yield of rice genotypes and also studied correlation between yield and zinc content. The experiment was comprised of 20 genotypes and three treatments viz., T1: Control (no zinc); T2: Soil application of ZnSO4 (20 kg ha-1) T3– Foliar Spray of ZnSO4 @ 0.5% at 50% flowering, laid out in factorial randomized block design with two replications. The data revealed that application of ZnSO4 recorded significantly higher plant height (85.9 cm), leaf area (764.5 cm-2 plant-1), number of tillers (95.4 m-1), total dry weight (26.1 g plant-1), panicle weight(15.3 g plant-1), number of panicles (81.6 m-1) and grain yield(3966 kg ha-1) over the foliar application of Zn and control . However number of grains panicle-1 (97.8 panicle-1), test weight (23.7 g), shoot and seed zinc content (15.9 and 21.2 ppm, respectively) were increased with foliar application of Zn. Correlation studies classified the genotypes as high seed zinc content (> 21 ppm) and low seed zinc content genotypes ( less than 21 ppm). High and low seed zinc content genotypes showed negative correlation with yield and yield attributes. However, shoot zinc content was positively correlated with yield.

Performance of different Tricho-inocula (Trichoderma harzianum inocula), Tricho-compost (T. harzianum compost) and Provax 200 WP (Carboxin + Thiram group fungicide) for controlling seedling mortality of chickpea was investigated under Sclerotium rolfsii and Fusarium oxysporum f. sp. ciceri inoculated soil in two different agro-ecological zones viz. Bangladesh Agricultural Research Institute (BARI), Gazipur and Pulses Research Station, Madaripur of Bangladesh. Tricho-compost was prepared with a mixed substrate of cow dung, rice husk and poultry refuse colonized by T. harzianum. The seedling mortality of chickpea was significantly reduced by the Tricho-inocula, Tricho-compost and Provax 200 WP where Tricho-compost was found superior with respect to reduction of seedling mortality and accelerating plant growth with increasing grain yield of chickpea under pot culture as well as field conditions in two different agro-ecological zones of Bangladesh

Chickpea is one of the important winter legumes in Nepal. It is grown after rice or maize either as sole or mixed crop. In Nepal, chickpea is mostly grown as rainfed crop on residual soil moisture or sometimes under irrigation. Lack of irrigation results drought and heat stress which affects crop growth and development. Irrigation at proper time is one of the most important factors for achieving higher crop yield.  The experiment regarding use of supplementary irrigation time on chickpea was carried out at Regional Agricultural Research Station, Khajura, Banke, Nepal during the winter season of the year 2011 and 2012. The experiment was laid out in Randomized Complete Block Design with three replications. Seven different time intervals of irrigation was applied in the experiment for both years. Treatments differed significantly in terms of grain yield but showed non -significant difference in days to flowering and maturity over the years. The combined analysis of the experiments showed that the highest grain yield (2318 kg/ha) was produced when irrigation was supplied at vegetative stage followed by irrigation supplied at flowering stage (2298 kg/ha) and pod fill stage (2104 kg/ha) respectively.Int J Appl Sci Biotechnol, Vol 3(3): 431-433

Two field experiments were conducted at Regional Agricultural Research Station, Tarahara, Nepal during 2012 and 2013 to determine the effect of agronomic management on growth and yield of Swarna Sub1 under flash floods. The first experiment was laid out in a split plot design with three replications; and four different nutrient combinations at nursery as main plots and three age groups of rice seedlings as sub plots. The second experiment was laid out in a randomized complete block design and replicated thrice; with three post flood nutrient doses at six and 12 days after de-submergence (dad). The experiments were complete submerged at 10 days after transplanting for 12 days. The survival percentage, at 21 dad, was significantly higher in plots planted with 35 (90.25%) and 40 (91.58%) days-old seedlings compared to 30 days-old seedlings (81.75%). Plots with 35 days-old seedlings produced 5.15 t ha-1 with advantage of 18.83% over 30 days-old seedlings. Plots with 100-50-50 kg N-P2O5-K2O/ha at nursery recorded the highest grain filling of 79.41% and grain yield of 5.068 t/ha with more benefit. Post flood application of 20-20 N-K20kg/ha at 6 dad resulted in higher plant survival and taller plants, leading to significantly higher grain yield of 5.183 t/ha and straw yield of 5.315 t/ha. Hence, 35-40 days old seedlings raised with 100-50-50 kg N-P2O5-K2O /ha in nursery and the additional application of20-20 kg N-K2O /ha at 6 dad improved plant survival and enhanced yield of Swarna Sub1 under flash flood conditions. The practice has prospects of saving crop loss with getting rice yield above national average yield leading to enhanced food security in the flood prone areas of Nepal.
