Mungbean is one of the important grain legume crops in Pakistan due to its vigorous growth even in adverse environment. Mungbean is part of daily cuisine in the country but its production is low mostly due to imbalance fertilization. The study was carried out to find best combination of nitrogen (N), phosphorus (P) and potassium (K) for maximum production under less fertile soils during 2017-2018. In this study, three combinations of NPK (i.e., 30:30:0, 30:60:0 and 30:60:30 kg ha-1 ) were compared with control (without fertilization). Maximum pods per plant (22.43), pod length (9.51 cm), seeds per pod (8.97), 1000 seed weight (44.07 g), seed yield (1163 kg ha-1 ), biological yield (5231 kg ha-1 ) and harvest index (24.63 %) were obtained from 30:60:30 kg NPK ha-1 during 2017 and similar trends were found during 2018. Maximum leaf area duration (212.64, 215.09 days), crop growth rate (3.99, 4.02 g m-2 d -1 ), net assimilation rate (2.46, 2.54 g m-2 d -1 ) and fraction of intercepted radiation (0.89, 0.88 MJ m-2 ) were obtained from mungbean plant under 30:60:30 kg ha-1 NPK application during 2017 and 2018, respectively. These results are suggesting that integrated application of nitrogen, phosphorous and potash is very imperative to attain higher production of mungbean under semi-arid environments. It is concluded from the findings that farmers can harvest maximum final outputs of mungbean by the application of 30:60:30 kg ha-1 NPK, respectively.

ABSTRACT: Two-year field experiments were conducted to investigate the phytotoxicity of mesquite (Prosopis juliflora) on weed control and yield of wheat in 2013-14 and 2014-15. Mesquite aqueous extracts were prepared with 10, 20, 30 and 40% concentration of leaves, stems, and roots and were compared with tap water (control). These experiments were laid out in a completely randomized block design with four replications. All parameters (weed density, fresh weed biomass, dry weed biomass, chlorophyll content, leaf area index, leaf area duration, crop growth rate, net assimilation rate, plant height and number of tillers) were significantly reduced by applying the mesquite extracts. Among different concentrations, the maximum level (40%) of all three plant parts of mesquite subsequently reduced the study parameters including weed density, fresh and dry weed biomass, leaf area index, leaf area duration, crop growth rate, net assimilation rate, chlorophyll contents, plant height, number of tillers, spike length, number of grains, 1000-grain weight, grain yield, biological yield, harvest index and grain protein content. On the basis of the results, it is concluded that aqueous extracts of mesquite may contain many phytotoxic substances which can negatively affect the growth and yield of agricultural crops; therefore, wheat should not be planted close to mesquite.

The effects of five stake weights (50, 63, 75, 88 and 100 g) of three cassava cultivars (TMS 30572, TMS 91934 and NR 8083) on the growth and yield of cassava were studied for 2 years (1992/93 and 1993/94) in Nigeria. The leaf area index (LAI), crop growth rate (CGR), net assimilation rate (NAR), leaf area duration (LAD), harvest yield and harvest index (HI) were dependent on the weight of stake planted and were greatest at the stake weight of 88 g (875 kg/ha) irrespective of cassava cultivar. Variations in LAI, LAD and HI of stake weights between 75 and 100 g were non-significant. The profusely branching cassava cultivars, TMS 30572 and NR 8083, achieved greater LAI, CGR, NAR and LAD relative to the sparsely branching cultivar, TMS 91934. The significant growth and yield differences among the stake weights with the optimum at a stake weight of 88 g (875 kg/ha) indicates the need to adopt this stake weight for sustainable and improved growth and yield in cassava production.

An investigation was made to see the effect of different concentrations (10, 20, 30 and 40 ppm) of 2, 3, 5- triiodobenzoic acid (TIBA) on leaf area index (LAI), leaf area duration (LAD), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) of a cultivar of chickpea (Cicer arietinum L.) grown during rabi season of 2015 - 2016. Results revealed that LAI and LAD showed a positive response from flowering stage to maturity (66 - 110 DAS) due to 30 ppm TIBA application with maximum LAI and LAD occurring at the flowering stage. At 66 - 83 and 83 - 97 DAS, CGR was highest with the application of 30 ppm TIBA, while RGR was highest due to 10 ppm TIBA. Peak CGR was recorded at the time of pod setting to pod filling stage (8 - 97) and increased over control by 29.64%. Irrespective of the treatments, NAR was recorded maximum during flowering stage to pod setting (66 - 83 DAS) and thereafter decreased till maturity. At 66 - 83 and 83 - 97 DAS, maximum NAR values were recorded due to 30 ppm TIBA and the increases were 9.09 and 32.69% higher over the control, respectively.Journal of Bangladesh Academy of Sciences, Vol. 40, No. 2, 199-205, 2016

AbstractWe have investigated the effects of saline irrigation on growth and water relations of two sun-cured tobacco genotypes, Xp102 and Px107, which belong to the Xanthia and Perustitza tobacco ecotypes, respectively. We compared three commercial sea salt concentrations of the irrigation water (0.25%, 0.5%, and 1% w/v) plus a non-salinized control, corresponding to an electrical conductivity (ECw) of 4.4, 8.5, 15.7, 0.5 dS m-1 and osmotic potentials of -0.22, -0.35, -0.73, -0.02 MPa, respectively. The ECsoil increased with the salinity of the irrigation water. At high salinity (1%), the soil where Px107 plants were grown showed a significantly higher salinity compared to the soil of Xp102. For both genotypes, the soil water content increased at increasing salinity and during the growth season. Increasing salinity progressively reduced the leaf turgor pressure and enhanced the cellular osmotic adjustment. The latter resulted to be more pronounced in Px107 compared to Xp102 (0.36 vs. 0.20 MPa). At higher salinity (0.5% and 1%), both genotypes showed reduced leaf surface area, dry matter accumulation, water use, net assimilation rate (NAR) and crop growth rate (CGR). Px107 roots were more sensitive than shoot to salinity (3% reduction per dS m-1) and compared to Xp102 roots, which showed a reduced development only at 1% salinity. Assessment of plant salt tolerance according to the Maas and Hoffman model revealed a slope of 1-2% for both genotypes, indicating that these tobaccos are relatively more salt tolerant compared to other species.

Two field experiments were conducted in two successive seasons, 2005/2006 and 2006/2007, to determine whether management can improve faba bean competitiveness with weeds, thus helping to achieve its yield potential. The experiment included five treatments, composed of organic and mineral fertilizers, alone and mixed at different rates, along with a control and six weed control treatments, including oxadiargyl, prometryn, hand hoeing treatments alone or mixed with the herbicides, and a nonweeded treatment (control).The herbicide treatments were not superior to the two hand-hoeing treatments. Using compost favored growth and yield of faba bean more than of weeds. Adding fertilizer also improved most yield parameters. Application of compost alone or combined with 50 or 100% of the recommended NPK rate improved faba bean growth in terms of net assimilation rate, specific leaf area, and leaf weight ratio as components of relative growth rate. This improvement in growth resulted in increase of seed yield, yield components and protein of faba bean. Faba bean yield performance improved under interactive fertilizer effects and weed control treatments as growth improved, as a result of nutrient release from fertilizers and weed control.

The field experiments were carried out during rabi season of 2009-10 and 2010-11 at the Research Farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Chatha to assess the physiological growth indices in chickpea+mustard intercropping system under different weed management practices. The significant superiority of replacement series treatment for leaf area index of chickpea over additive series treatment was noticed. The crop of sole chickpea was followed by replacement and additive series treatments in recording highest dry matter, crop growth rate and net assimilation rate values. Sole stand of chickpea recorded numerically higher relative growth rate (RGR) followed by replacement and additive series treatments. Weed free treatment recorded numerically the highest crop growth rate (CGR) and net assimilation rate (NAR) of chickpea at all the stages of observation. Sole chickpea produced higher yield as compared to chickpea+mustard when grown in additive and replacement series in the respective order.

A field experiment was conducted at Regional Research Station (Punjab Agricultural University) Gurdaspur and Krishi Vigyan Kendra, Pathankot during the spring season of 2016, to determine the performance of kidney bean genotypes at different sowing dates under sub-mountainous conditions of Punjab. The two kidney bean genotypes i.e. red and speckled were evaluated for yield potential at two locations by adopting different sowing dates viz., 20th January, 1st February, 10th February and 20th February, 2016. The treatments were laid out in split plot design with four replications by keeping sowing dates in main plots and genotypes in sub plots. Among different dates of sowing, crop sown on 10th February showed superiority than other dates through higher emergence count per meter row length, plant height, branches per plant, pods per plant, seeds per pod, length of pod, biological yield and seed yield. The seed yield in February 10 sown crop was 66.4, 33.3 and 21.7 per cent higher than February 20, January 10 and February 1 sown crop, respectively at Gurdaspur. Similarly, at Pathankot, the percent increase in seed yield in February 10 sown crop was 36.0 and 7.2 per cent as compared to February 20 and February 1 sown crop, respectively. The kidney bean genotype speckled produced significantly higher yield attributes (seeds per pod, length of pod and 100 seed weight) and seed yield at both Gurdaspur and Pathankot (935.1 and 823.1 kg per ha, respectively) as compared to red genotype. Therefore, it can be concluded that to attain higher productivity of kidney beans, the speckled genotype could be used for cultivation by adopting February 10 as the optimum time of sowing in the sub-mountainous area of Punjab.

Background: The main pulses grown in India are chickpea, arhar, lentil, black gram, mung bean, moth bean, horse gram, pea, khesari, cowpea, etc. Black gram is fourth major pulse crop in India, that contributes 13 and 10 per cent of total area and production respectively. This is annual plant that attains 30-100 cm height and its stem is covered with brown hairs and much branched from the base. The pods are long and cylindrical being 5-6 cm length and 4-10 seed in pods. The seeds are generally black, very dark brown. Methods: The field experiment was conducted in kharif-2019 at research farm of Tirhut College of Agriculture Dholi, to study the effect of integrated nutrient management on growth, yield parameters and the yield of black gram cv-PU-31, by the use different sources of nutrient in a integrated manner such as three level of fertilizer i.e. F1-75, F2-100 and F3-125% RDF and two levels of organic manure i.e. M1-control and M2-FYM @ 5 t ha-1 and three levels of biofertilizer i.e., B1-rhizobium, B2-nutrient mobilizer, B3-rhizobium+ nutrient mobilizer. The treatments were allocated in randomized block design (factorial) and replicated thrice. Result: The results revealed that F3 produced taller plants, more dry matter, crop growth rate (CGR) yield attributes resulting higher yield of grain and straw (10.78, 22.61 q ha-1 respectively) which was statistically at par with plant height, dry matter, crop growth rate, yield attributes and yield of grain, straw and highest harvest index (10.73, 22.20 q ha-1 and 32.58% respectively) to F2. Among addition of organic manure significantly maximum plant height, dry matter and crop growth rate and yield attributes resulting maximum yield of grain, straw and harvest index (11.2, 22.79 q ha-1 and 33.31% respectively) was found in M2 over M1. In biofertilizer treatments, B3 recorded higher plant height, dry matter and crop growth rate, yield attributes resulting in significantly higher yield of grain, straw and harvest index (10.26, 21.90 q ha-1 and 31.92% respectively) over B1 and B2.
