Foliar applications of 500 and 1000 ppm KNap and 2 and 4 ppm mixtalol on Kanchan and Akbar varieties of wheat showed that in most cases spikelets per plant, grains per spikelet, weight of 1000 grains and grain yield per plant increased significantly. In Kanchan the highest yield was due to 4 ppm mixtalol and in Akbar it was due to 500 ppm KNap.

Background: Blackgram [Vigna mungo (L.) Hepper] is one of the most important cultivated legume crops with high nutritive value and agricultural importance. The productivity of blackgram is not adequate to meet the domestic demand of the growing Indian population. Consequently, there is an urgent need for enhancement of productivity through proper agronomic practices. With this background, a research experiment was conducted in a farmer’s field at Pudhupalayam, Coimbatore to investigate the effect of foliar application of PPFM, plant growth regulating compounds and nutrients on growth, yield attributes, yield and economics of irrigated blackgram. Methods: A field experiment was laid out in randomized block design with three replications during 2019 (kharif and rabi) season. The treatments include 100% recommended dose of NPK along with foliar application of diammonium phosphate (DAP), brassinolide (Br), salicylic acid (SA) and pink pigmented facultative methylotrophs (PPFM) with different concentration (1%, 2%, 1 ppm, 2 ppm, 50 ppm, 100 ppm, respectively) in addition to control. PPFM and PGRs were sprayed at 30 and 45 days after the sowing of blackgram. Result: The experiment results of the two seasons study revealed that the application of 100% RDF + PPFM @ 2% recorded higher growth characters viz., plant height (cm), number of branches plant-1, leaf area index and yield attributes viz., number of pods plant-1, number of seeds pod-1, pod weight (g), pod height (cm), 100 seed weight (g) and yield viz., grain yield (kg/ha), straw yield (kg/ha) and harvest index (%). As well as the same treatment recorded higher net return and B:C ratio. Correlation and regression analysis also indicated that the yield attributes had a positive impact on the grain yield with a magnitude of 1.91 and 1.67, respectively. Therefore, application of 100% RDF+2% PPFM spray can be recommended as the best technology to improve the yield and economics of blackgram.

Effects of 100 and 200 ppm of naphthalene acetic acid (NAA) on yield attributes and yield of two varieties of rice during 2009 - 2010 Boro season were evaluated. The highest plant height was observed due to 200 ppm in both BRRI dhan-29 (V1) and BRRI dhan-50 (V2). Number of tillers per plant were found to increase due to 100 ppm NAA only in BRRI dhan-29 and varied non-significantly. Yield attributes, viz. number of branches per panicle, number of grains per panicle and filled grains per panicle increased in BRRI dhan-29, following both 100 and 200 ppm NAA, whereas, most of the yield parameters decreased in BRRI dhan-50. Due to 100 and 200 ppm NAA, grain yield per plant increased by 27.67 and 6.85%, respectively in BRRI dhan-29 though not statistically significant. However, in BRRI dhan-50 grain yield per plant decreased by 26.54% due to 100 ppm and 27.67% due to 200 ppm. Out of the two concentrations 100 ppm NAA produced better stimulation.

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.

A field study was conducted during Rabi season of 2019-20 on “Response of Iron and Zinc on Yield Attributes, Yield and Economics of Wheat (Triticum aestivum L.)” at Research Farm of Vivekananda Global University, Jaipur. The treatments comprised different combinations of recommended dose of fertilizer and micronutrients. Results showed that the yield attributes and yield net returns and benefit cost ratio of wheat was significantly increased due to application of different treatment combinations of zinc and iron. The maximum number of effective tillers m-2, grains spike-1, spike length, grain yield (4887 kg ha-1), straw yield (6718 kg ha-1) and biological yield (11606 kg ha-1) of wheat was obtained with RDF + soil application of ZnSO4 @ 25 kg ha-1 + FeSO4 @ 50 kg ha-1 (T10). Application of RDF + soil application of ZnSO4 @ 25 kg ha-1 + foliar application of ZnSO4 (0.5%) at tillering stage (T6) gave highest net returns ( 65168 ha-1) and B: C ratio (2.83).

Increased crop competitiveness may complement existing weed control methods. The objective of this research was to establish whether spring wheat (Triticum aestivum L.) genotypes with contrasting competitive abilities respond differently to weed control levels. Four sibling genotypes differing in competitive ability were grown under simulated weedy conditions and subjected to four weed control levels. The competitive genotypes were superior to the less-competitive genotypes in grain yield under weedy and partially weedy conditions.

Abstract: The objective of this work was to evaluate nitrogen management alternatives using Azospirillum brasilense inoculation in wheat (Triticum aestivum) by seed and foliar applications. Treatments consisted of the inoculation or not of A. brasilense, via seed and leaves, associated with topdressing with 0, 70, and 140 kg ha-1 nitrogen. Three wheat cultivars were tested: BRS Parrudo, TBIO Quartzo, and TBIO Sinuelo. The experimental design was a randomized complete block, with three replicates. The following traits were evaluated: number of emerged plants, tillers, spikelets per ear, grains per ear, and grains per spikelet; 1,000-grain mass; hectoliter mass; and grain yield. The foliar management of A. brasilense showed a better association with the TBIO Sinuelo cultivar. The foliar application of A. brasilense, whether alone or combined with seed treatment, increases the grain yield and yield components of the evaluated cultivars.

The Cultivars are Latifia , AL-Rasheed and Iba 99. The growth regulators are Alga600, Atonik and Azomin32%. Factorial experiment in R.C.B.D.  with three replicates is used . The results showed that Iba 99  Cultivar gives the highest plant height , Spikes/m2 and grain yield , with a means 80.83 cm , 272.25 spike/m2 and 3.06 Ton/h) Respectively . Azomin32%  growth regulator gives the highest grain /spike , 1000 grain weight and grain yield , with a means 66.00 seed/spike ,43.55 gm , 272.33 spike/m2  respectively. In addition the interaction between Iba 99 Cultivar  and Azomin32% growth regulator gives the highest Leaf Area , number of grain/spike and grain yield with means 45.10 cm2 , 70.00 grain/spike and 3.16 ton/ha respectively.The combination treatment Iba 99 with Atonik growth regulator gives the highest number of spike/m2  with a mean 279.66 spike/m2  . In the other hand, the same cultivar with Atonik and Azomin32% gives the highest mean of grain yield with a amount 3.16 ton/ha.
