An experiment to find out the wheat growth as affected by foliar application of potassium Sulphate (K2SO4) on different growth stages under rainfed conditions was conducted at the Agricultural Research Institute, Dera Ismail Khan, Pakistan. Potassium doses viz. 0, 12, 18, 24, 30 and 60 kg ha-1 were applied in foliar form at tillering, booting and heading stages of wheat. The course of study revealed that foliar application of K2O in booting stage produced maximum leaf area index (LAI), leaf area duration (LAD), crop growth rate (CGR), net photosynthesis rate (NPR) and grain yield, while its application at heading stage produced maximum net assimilation rate (NAR). Among different doses, the application of potassium at the rate of 60 kg ha-1 potassium at the rate of 60 kg ha-1 produced maximum growth and yield and its components during two consecutive cropping seasons of wheat crop while weed density (m-2), relative weed density (%), fresh weed biomass (g m-2) and dry weed biomass (g m-2) influenced non-significantly for both the years. These findings suggest that foliar application of potassium sulphate @ 60 kg ha-1 along with recommended dose of nitrogen (120 kg ha-1) and phosphorus (90 kg ha-1) is the most suitable for successful wheat production under rainfed conditions.

Wheat is one of the most important cereal crop and staple foods in the world. Increase in productivity of wheat by balance nutrient management is one of the most crucial factors. The main objective this study is to assessing the role of micronutrients in improving different components of wheat yield. There are different methods of application such as seed priming, soil application and fortification but foliar application is more beneficial. This is due to response of foliar application has positive and quadrate in nature i.e. the optimum dose of foliar application of zinc for grain yield of wheat was observed as 0.04%. Among treatments of micronutrient alone or combined forms give better results over control. Results have show that micronutrient application substantially improved leaf area index (LAI), leaf area duration, CGR (Crop growth rate), RGR (Relative growth rate), NAR (Net assimilation rate), plant height, spike length, spikelets/spike, grains/spike, test weight, tillers m-2, grain yield, chlorophyll content and biological yield as well as harvest index of wheat. The yield and quality of wheat products improved and boosted by micronutrient applications. Therefore, human and animal health will be protected with the feed of enriched and balanced nutrition of produce as well as it will help in facing the severe global food security.

Chitosan is biopolymer of glucosamine residues, nontoxic, biodegradable and friendly to environment and it also helps to enhance crop production due to their bioactivities. The present experiment was conducted to assess the efficacy of chitosan on the growth and yield related attributes of mulberry, Morus sp. with various concentrations such as 25, 50, 75, 100 and 125 ppm. The chitosan was sprayed thrice on 15, 30 and 45 days after pruning (DAP) on the foliage of three different mulberry varieties namely V1, MR2 and G4. The result revealed that, irrespective of varieties, the foliar application of chitosan at 75 ppm significantly increased the biometric as well as yield related attributes of mulberry over other concentrations. Among the three varieties, V1 showed more response to chitosan application than G4 and MR2. At 75 ppm, chitosan showed marked effect on VI variety of mulberry and significantly increased shoot length (170.67 cm), number of shoots per plant (9.03), number of leaves per shoot (29.48), leaf area (220.26 cm2) and leaf area index (2.72) were observed when compared with control. The application of chitosan at 75 ppm significantly enhanced the yield traits namely weight of 100 leaves (448.10 g), leaf shoot ratio (1.45) and leaf yield (14.01 MT/ha/harvest) in V1.

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.

Leaf area index (LAI) is a measure of leafiness per unit ground area and denotes the extent of photosynthetic machinery is an important growth and yield-determining factor because it is a major determinant of light interception and transpiration. Phosphorus (P) and zinc (Zn) and rate are the most important factors affecting leaf area index (LAI) of rice(<em>Oryza sativa</em> L.). A field experiment was conducted to assess the impact of phosphorus (0, 40, 80, 120 kg P ha<sup>-1</sup>) and zinc levels (0, 5, 10, 15 kg Zn ha<sup>-1</sup>) on LAI of rice (<em>Oryza sativa</em> L.) genotypes [fine (Basmati-385) and coarse (Fakhr-e-Malakand &amp; Pukhraj)]. The experiment was conducted on farmer field at Batkhela, Malakadnd in Northwest Pakistan during summer 2011 and 2012. When combined over the two years, the data revealed that the highest LAI at three different growth stages (tillering, heading and physiological maturity) was obtained with application of the highest P level (120 kg ha<sup>-1</sup>) being at par with 80 kg P ha<sup>-1</sup>, while the lowest LAI was recorded when P was not applied. Similarly, the highest LAI was obtained with application of the two higher Zn levels (10 and 15 kg Zn ha<sup>-1</sup>), while the lowest LAI was recorded when Zn was not applied. In case of rice genotypes, the highest LAI was obtained from Pukhraj than other two genotypes at all growth stages. The other two rice genotypes (Fakher-e-Malakand and Basmati-385) produced statistically similar LAI at different growth stages. The higher LAI of Pukhraj was attributed to its long and wider leaves that resulted in higher mean single leaf area, leaf area per tiller, per hill and per square meter. The LAI was highest at heading stages than at early (tillering) and later (physiological maturity) growth stages. The increase in LAI was attributed to the increase in tillers number and leaf area hill<sup>-1</sup>. The increase in LAI showed positive impact on crop growth rate, dry matter accumulationand yield. Application of 120 kg P + 10 kg Zn ha<sup>-1</sup> to rice genotype Pukhraj was more beneficial in terms of higher LAI and productivity in the study area.

Maize is staple food and the most cultivated crop in Eswatini. However, its yield is very low partly due to use of non-optimum plant density for different maturity group maize varieties. Thus, an experiment was conducted at Luyengo, Middleveld of Eswatini during the 2018/2019 cropping season. The experiment consisted of factorial combinations of two varieties [SC 403 (early maturing) and PAN 53 (medium maturing)] and three plant densities (44444 plants/ha, 50000 plants/ha, 57143 plants/ha) in randomised complete block design in three replications. Results showed that medium maturing maize variety PAN 53 had higher leaf area, leaf area index, plant height, cob height (139.4 cm), days to 90% anthesis (69 days), dry biomass, thousand kernels mass (374.0 g), grain yield (43.1 t/ha), and stover mass (59.8 t/ha) than the early maturing variety SC 403. With respect to the effect of plant density, as the plant density increased from 44444 to 57143 plants/ha, leaf area, dry biomass at V12 and R5 growth stages, number of cobs per plant, grain yield, stover mass, and thousand kernels mass (g) were decreased while the leaf area index was increased. The interaction effects of variety and plant density were not significant on all the parameters recorded. Thus, it can be concluded that medium maturing variety PAN 53 and plant density of 44444 plants/ha (90 cm ´ 25 cm) are best options to maximum productivity of maize in the study area. However, it is recommended that the experiment be repeated with inclusion of more varieties and densities to reach at more conclusive recommendation.

A field experiment was conducted during the summer, 2014 at College of Agriculture, Vellayani, Kerala to evaluate the influence of irrigation levels, nitrogen stress and method of application of fertilizers on growth and yield of yard long bean. The experiment consisted of four levels of irrigation, two levels of nitrogen and two methods of application. The results indicated that daily irrigation at 10 mm depth and recommended dose of nitrogen (30 kg ha-1) recorded superior values for growth parameters viz., functional leaves per plant and leaf area index The major yield attributes like number of pods per plant and pod yield per plant and total pod yield were not influenced by levels of irrigation and nitrogen indicating that irrigation once in three days at 20 mm depth and nitrogen level of 22.5 kg ha-1 is sufficient for yard long bean. Soil and foliar application of nitrogen and potassium recorded superior growth characters, however, the yield was superior when the recommended dose of nutrients were supplied as soil application. Increasing irrigation interval to three days and imparting N stress did not result in any reduction in gross income and net income while, a higher benefit: cost ratio was noted in irrigation at wider intervals. Soil application of nutrients recorded higher gross income, net income and BCR compared to soil + foliar application.

Shallot (Allium cepa L. Aggregatum group) is one of the most widely utilized vegetables by Indonesian people. Some technologies have been adapted to improved shallot productivity. One of those are the application of beneficial microorganisms. We applied mycorrhizal fungi, Trichoderma sp., and Bacillus thuringiensis as well as the combination among these microorganisms were applied in Shallots cultivation and were investigated to improve the growth and development of shallot. A field experiment was arranged in a Randomized Complete Block Design with two treatment factors. The first factor consisted of two shallot cultivars, namely Biru Lancor and Crok Kuning; whilst the second factor consisted of six beneficial microorganism treatments, i.e. control, mycorrhizae, Trichoderma sp., Bacillus thuringiensis, the combination of mycorrhizae and Trichoderma sp., and the combination of those three microorganisms. The observation was conducted on infection percentage of mycorrhizae, total population of Trichoderma sp., leaf area, leaf area index, net assimilation rate, crop growth rate, harvest index, and plant yield. The data obtained were subjected to analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT) at 5% significance level. The results showed the leaf area of shallot was improved as affected by the application of mycorrhizal fungi. The effectiveness and implication of mycorrhizal fungi on shallot growth would decrease if the application of was combined with other microorganisms. However, the application of beneficial microorganisms had not been able to increase component yield and yield of Biru Lancor and Crok Kuning, indicated by bulb weight, number of bulb, bulb diameter, number of bulb per cluster, and bulb yield per hectare.
