<div>Background: The Zinc deficiency is a worldwide nutritional constraint for crop production in many types of soil. Appropriate application methods of Zn fertilizer are still unclear. The main objective of this study was to investigate the effects of Zn fertilizer and application methods on the growth characteristics of Vigna unguiculata.&nbsp; 
 
Methods: The present study was conducted to evaluate the effects of Zinc fertilizer and application method on photosynthetic characteristics and yield of Vigna unguiculata from June to September of 2019, in Jaipur, Rajasthan, India. A pot experiment was conducted as a factorial design with 3 replications.&nbsp; 
 
Result: The application of 15 kg ZnSO4.7H2O/ha increased chlorophyll content in leaves, improved photosynthesis and increased protein content of Vigna unguiculata, when applied as foliar application as opposed to being applied in basal application. These results have important implications for guiding the rational application of Zinc fertilizer and improving the yield of Vigna unguiculata.</div>

​Effectiveness of Foliar and Soil Application of Zinc Fertilizer on Growth Characteristics of Vigna unguiculata

Background: We aim to determine the effects of RGB reflectance index and chlorophyll contents on yielding of 15 durum wheat genotypes growing under semi-arid conditions.&nbsp; 
 
Methods: The genotypes tested were sown in a random block design with three replications.The following traits were measured from the head, number of days to heading, RGB reflectance index by numerical images analysis of flag leaves and using Mesurim Pro (version 2.8) software and Chlorophyll contents. Grain yield, thousand kernels weight, number of spikes per meter square, and plant height were measured at maturity. 
 
Result: ANOVA showed that genotype effect significant for all traits. The local landrace Boutaleb witch was the best yielding genotype registered a low red reflectance index and an average green reflectance index, blue reflectance index and chlorophyll contents. The study of the correlations reveled that chlorophyll contents was significantly and negatively correlated with reflectance index at red and blue bands and very significantly and positively correlated with reflectance index at green band. PCA showed thatgrain yield was affected by number of spike per mete square, a negative relation was observed between chlorophyll contents and RGB reflectance index.

<div>Cotton is one of the most important cash crop grown for its fibre, which is the raw material for the textile industry. In India, the average yield and profitability of cotton cultivation are low as compared to developing countries. The main reason for this is hand picking of bolls, which is labour intensive resulting into low income of cotton growers. Furthermore, in India, most of the cotton varieties are indeterminate where the bolls do not mature at the same time and thus requires repeated hand pickings. Whereas the developed countries have 100% mechanized cotton picking due to determinate or semi-determinate plant types. Adoption of mechanical harvesting in India is dependent upon the availability of suitable cotton varieties as well as defoliants, desiccants, boll openers, growth hormones and re-growth inhibitors (Thatikunta et al., 2018). Defoliation before cotton harvesting is very important to maintain the quality of produce. In this paper, a comprehensive review is presented on effect and timing of application of defoliants on physiological characteristics of cotton. This will help in developing further research proposals to develop plant types for mechanical harvesting and use of defoliates to produce good fiber quality and increased farm income.</div>
