This study evaluated the role of gibberellic acid [GA3; (0, 100, 200, and 300 ppm)] in modulation of the growth, physiology, yield, and quality traits in two varieties (BARI Mung-6 and BARI Mung-8) of mungbean (Vigna radiata L.). Irrespective of the two varieties (BARI Mung-6 and BARI Mung-8), 100, 200, and 300 ppm of GA3 differentially modulated the tested parameters (relative water content, RWC; photosynthetic pigments: chlorophyll a, chlorophyll b, and carotenoids; growth parameters: fresh and dry weights of leaves, petioles, stems, and roots; yield contributing traits such as plant height, number of pods plant−1, number of grains pod−1, pod length, and 100-grain weight; quality traits such as grain nitrogen and protein). However, compared to the lowest GA3 (100 ppm) and the highest GA3 (300 ppm), the moderate concentration of GA3 (200 ppm) led to highest values of leaf-RWC, where this parameter exhibited 16.1 and 13.4% increase in BARI Mung-8 and BARI Mung-6, respectively. Similarly, the tested herein growth parameters and the yield traits significantly increased up to the foliar application of the moderate GA3 concentration (200 ppm), and thereafter these traits decreased with 300 ppm GA3. The 200 ppm-led changes in the growth and yield traits were significantly higher in BARI Mung-8 when compared to BARI Mung-6. Considering the quality traits, GA3 positively influenced the nitrogen and protein content in grains, where 200 ppm of GA3 led to increases of 25.2% in N, and 17.7% in protein over control in BARI Mung-6; whereas, BARI Mung-8 exhibited 28.3% in N, and 18.3% in protein with 200 ppm GA3 over control. Overall, BARI Mung-8 significantly responded to the foliar supply of 200 ppm GA3 when compared to BARI Mung-6. Hence, in order to high yield and grain protein content, the application of 200 ppm GA3 may be applied in V. radiata before and during flowering. The major mechanisms underlying the responses of the water relation, growth, and yield traits to the GA3 concentrations need to be explored.

The present investigation was carried out during 2016-2017 with the objective of observing the effect of the tested systems of pruning on vegetative, fruiting, yield and quality traits of capsicum varieties. The experiment was laid out in a factorial randomized block design with four replications and nine treatments with Indra, Bachata and Inspiration cultivars of capsicum pruned with three intensities i.e. two shoots, four shoots and un-pruned (control). The results showed that the two stem pruning treatment significantly affected the plant growth and flowering characteristics in terms of plant height (194.75cm), number of days to first flower (20.25 days) in cv. Indra. Same cultivar when left un-pruned recorded more number of fruits per plant (23.64 fruits), but fruit yield per plant (4.14kg) was observed in four stem pruning treatment in Indra cultivar of capsicum than other cultivars tried.

Potassium (K) has a significant effect on wheat yield and quality. Owing to the limitations of irrigation and production costs, soil-based applications of potassium fertilizer are not performed in wheat production on the Loess Plateau of China. In the late growth stage of wheat, potassium deficiency occurs even under sufficient nitrogen/phosphorus (N/P) levels, so it is necessary to supplement potassium through foliar spraying. However, there are few studies on the effect of the foliar application of potassium fertilizer (KFA) on wheat quality. Field experiments were conducted at two experimental sites for 2 years to study the effects of different potassium fertilizer application levels and periods on wheat yield and quality. The results showed that KFA had no significant effect on the yield of the wheat variety Xinong 20 (XN20) but increased the yield of the wheat variety Xiaoyan 22 (XY22). The improvement effect of KFA on the wet gluten content and stabilization time (ST) of XN20 was better than that on these parameters of XY22, while the sedimentation value (SV) and formation time (FT) showed the opposite trend. KFA significantly reduced the albumin content of the two varieties but had no significant effect on the globulin content. Compared with that at the other two stages, the potassium application in the form of potash fertilizer spray at a concentration of 60 mmol L−1 (K2) at the flowering stage (BBCH 65) significantly increased the protein content, wet gluten content, SV and gluten protein content in XN20 grains, whereas the application at 10 days after flowering (AA10, BBCH 71) at the K2 concentration was more beneficial to prolonging the dough FT. For XY22, the application of potassium fertilizer at the K2 concentration at the flowering stage increased the wet gluten and gluten protein levels and dough development time. There were significant genotypic differences in the composition and content of HMW-GS between the two varieties. KFA significantly increased the levels of the 1, 7 + 8, and 4 + 12 subunits in XN20 and the 1 subunit in XY22, but had no significant effect on the 2 + 12 subunit in XY22. Partial least squares path modelling (PLS-PM) analysis showed that the processing quality indexes (SV, FT, ST) and gluten protein and HMW-GS levels were regulated by the potassium fertilizer foliar spraying stage and concentration and revealed in part that KFA affected the processing quality by affecting the HMW-GS content.

The high yield of ginger is function of adequate and timely supply of plant nutrients. Among the various agronomic technologies influencing the production of ginger, nutrition is found to exert a great influence on growth and yield of ginger. Imbalance, low or no fertilizer application is one of the most important factors in obtaining the poor yield. Hence, the trial was taken to study the effect of organic manures (FYM, neem cake, vermicompost, Azospirillum) and biostimulants (panchakavya, humic acid and PPFM) on growth, yield and nutrient uptake of ginger at Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore. The growth parameters like plant height, number of leaves, number of tillers and leaf area were found to be higher in the plants fed with 50% N (FYM) +25% N (Neem cake) + 25% N (Vermicompost) + Azospirillum (5kg/ha) + Panchakavya (3%). The maximum green rhizome yield (23.55 t ha-1) was obtained with the application of 50% N (FYM) +25% N (Neem cake) + 25% N (Vermicompost) + Azospirillum (5kg/ ha) + Panchakavya (3%) per hectare. The highest uptake of nitrogen (119.06 kg ha-1) and potassium (197.56 kg ha-1) was found in the application of 50% N (FYM) +25% N (Neem cake) + 25% N (vermicompost) + Azospirillum (5kg/ ha) + panchakavya (3%) per hectare The maximum amount of Phosphorus uptake (14.35 kg ha-1) was recorded in the application of 50% N (FYM) +25% N (neem cake) + 25% N (vermicompost) + Azospirillum (5kg/ha) + humic acid (0.1%). In ginger cultivation, the application of organic manures and inorganic fertilizers commonly practiced to increase the yield and quality of rhizome. Considering the world demand for organic food, the improvement of soil health, productivity and the availability of local resources, cultivation under organic farming can be encouraged.

Allelopathy and natural products are safe non-chemical modern techniques that applied as alternative to synthetic herbicides for controlling weeds. So, two pot experiments were conducted to evaluate the allelopathic effect of Psidium guajava leaf powder (PLP) and Acetic acid 5% as a natural product on the growth and yield of Capsicum annuum plants and both associated weeds: Phalaris minor (grassy weed) and Malva parviflora (broad-leaved weed). PLP was mixed with in the soil surface at successive rates (15, 30, 45 and 60 g/pot). In the corresponding treatments PLP at the same sequenced rates was mixed with the soil then sprayed with acetic acid 5% immediately. Moreover, sole spraying of acetic acid 5% treatment was sprayed on the soil surface. All treatments were applied before transplanting directly. Results revealed that the maximum inhibition of both weeds in both seasons was recorded by PLP at 60g + Acetic acid 5% as compared to unweeded control. Concerning to C. annuum growth parameters and yield traits, sole application of PLP at successive rates is more effective than PLP at the same successive rates with acetic acid 5%. So, it was observed that PLP at 60g/pot and 45 g/pot significantly developed most of growth parameters and yield traits of C. annuum than the healthy plants in both seasons. On the contrary, acetic acid treatment alone recorded the lowest value of all growth parameters and yield traits of Capsicum annuum plants.Allelopathy and natural products are safe non-chemical modern techniques that applied as alternative to synthetic herbicides for controlling weeds.

Zingiber zerumbet (L.) Smith, known as Lempoyang in Malaysia, belongs to the family Zingiberaceae. Previous studies on Lempoyang mainly focused on the chemical properties and biological activities of the rhizome extracts of this plant. Despite the tremendous demand for the rhizomes of Z. zerumbet, there is a lack of information on cultivation practices and a scarcity of planting materials. By using the pre-soaked technique, the challenges posed by Z. zerumbet dormancy can be overcome, obtaining good quality and uniform planting material throughout the year. Besides that, it is also crucial to determine the optimum shade level and NPK fertilizer rates to obtain a high yield and good quality rhizomes of Lempoyang. Six concentrations of 6-benzylaminopurine (BAP, 0, 50, 100, 150, 200, and 250 mg/L) and ethephon (0, 150, 300, 450, 600, and 750 mg/L) were tested to evaluate their effects on breaking rhizome dormancy. Three different shade levels (full sun, 30%, and 50% shade levels) and four combinations of Nitrogen (N), phosphorus (P), and potassium (K) (NPK) fertilizer at different rates were evaluated to study their effects on plant growth and yield performance. The results showed that BAP at 100 mg/L and ethephon at 300 mg/L performed better than the other compound concentrations tested in promoting the breaking of bud dormancy. A significant interaction effect was observed between shade levels and NPK fertilizer rates in all the growth parameters examined, except for the number of tillers per plant. Plants grown under 30% shade with NPK 4 produced the highest rhizome fresh weight, dry weight, and yield, but plants grown under 50% shade with NPK 4 showed the highest plant height and number of tillers per plant.

Boron is an important micronutrient, required for all plant growth, and critical for high yield and quality of crops. The aim of the present research was to determine the effects of boron on pot-grown parsley (Petroselinum sativum Hoffm.). The experimental design consisted of four treatments using Hoagland-Arnon (1950) nutrient solutions with two different boron concentrations (B1 - 15 ppm and B2 - 150 ppm), each with and without 10 ml humic acid addition (HB1 and HB2), and controls with full strength Hoagland-Arnon solutions. Growth analyses of the parsley revealed that 15 ppm boron application caused an increase in root length leaf fresh and dry weight root fresh and dry weight and leaf area compared to control values. 150 ppm B (B2) concentration decreased all growth parameters compared to controls. The two humic acid treatments (HB1 and HB2) did not increase any of those growth parameters either in controls (C) or in the two boron (B1 and B2) concentrations. Analysis by (ICP-MS) revealed that B content in the leaves increased gradually in B1 and B2, as well as in both humic treatments where in HB2 it increased to 99.38% compared to B1. In the leaves, Mn, Zn and Fe contents behaved the same as B, increasing in all treatments, with the amounts in HB2 being significantly greater than in C, B1 and B2 leaves.

Information on the inheritance of yield and quality traits is important for the selection of parents and breeding approaches to be adopted for the improvement of strawberry. The present study aimed to estimate the combining ability and gene effects for plant yield, fruits number/plant, fruit weight, pulp firmness and sugar content of strawberries in order to identify the best genitors and promising crosses, in 30 hybrids of six parents. The additive and non-additive gene action as well as the maternal effects was involved in the inheritance of the studied traits. For all traits, especially for fruit weight and plant yield, the additive gene action was more important than the non-additive one. The parents ‘A1’ and ‘Alba’ showed a higher concentration of favourable alleles for plant yield and fruits number, and they will allow the increase of plant yield when used as a donor of pollen and the increase of fruit number when used as a recipient of pollen. The variety ‘Marmolada’ was a good general combiner for sugar content, pulp firmness and fruit weight, especially when used as a female genitor. These parents could be used in hybridization in order to accelerate the genetic improvement of some yield and quality traits in strawberries. The cross ‘Mira’ × ‘Onda’ expressed desirable specific combining ability effects for yield traits and can be successfully use in strawberries breeding programs. In the case of ‘Alba’ × ‘Clery’ there is a high probability to select progenies with valuable yield traits associated with sweet fruits.

An experiment was conducted to investigate the mitigation of drought stress by foliar application of salicylic acid and potassium in mung bean. Treatments comprised of three drought stress (control, drought stress at flowering stage and drought stress at flowering and pod formation stages) and foliar application salicylic acid (100 ppm) alone and in combination with potassium (1%). Irrigation missing at flowering stage, affected less the growth and yield as compared with irrigation missing at both flowering and pod formation stage. Exogenous application of salicylic acid and potassium could mitigate the adverse effects of drought stress significantly.

Abstract The challenge of meeting the increasing demand for worldwide rice production has driven a sustained quest for advances in rice breeding for yield. Two breakthroughs that led to quantum leaps in productivity last century were the introduction of semidwarf varieties and of hybrid rice. Subsequent gains in yield have been incremental. The next major leap in rice breeding is now upon us through the application of rational design to create defined ideotypes. The exploitation of wide-cross compatibility and intersubspecific heterosis, combined with rapid genome sequencing and the molecular identification of genes for major yield and quality traits have now unlocked the potential for rational design.
