Nutri-millets offer copious micronutrients like vitamins, beta-carotene etc. In this present day, all the millets are amazingly superior and are therefore, the result for the malnutrition and obesity that affects a vast majority of the Indian population. They have numerous beneficial properties like drought resistant, good yielding in areas where water is limited and they possess good nutritive values. The prospective water scarcity in semi-arid regions disturbs both normal as well as managed environments, which limits the cultivation of crops, fodder, and other plants. The issues faced by the rain-dependent farming of these semi-arid regions are primarily the unpredictability of the monsoon. Probability analysis of rainfall events are believed to contribute in deciding sowing dates for the current season and for successful crop production in semi-arid environments. The present study was carried out in semi-arid condition to quantify the performance of nutri-millets in the rain dependent farming. The experiment was laid out under factorial randomized block design with 3 replications. The treatments comprises of crop factor viz., Sorghum [Sorghum bicolor (L.) Moench] (C1) and, little millet [Panicum sumatrense Roth ex Roem. & Schult] (C2) and sowing window factor viz., sowing based farmer’s practice (M1) i.e. on 31st standard meteorological week (SMW); Sowing at 33rd SMW based on 50% rainfall probability (M2); Sowing at 38th SMW based on 75% rainfall probability (M3), Sowing window as per the current weather forecast, for this season on 35th SMW (M4).It is evident from the study that Sowing sorghum at 38th standard meteorological week based on 75% rainfall probability recorded higher grain yield, rain water use efficiency with elevated iron and calcium content. This shows that different sowing dates have significant influence on grain yield and quality of nutri-millets.

The adverse effects of abiotic stresses have always restricted oilseed crop production, particularly in arid and semi-arid regions. On the other side, global climate change has led us to adapt planting dates and select tolerant cultivars to encounter the new climatic conditions. To evaluate the effect of late-season drought stress under different planting dates on rapeseed cultivars, an experiment was conducted as a factorial split-plot based on randomized complete block design in Karaj region- Iran, during 2015-2017. Planting date and irrigation treatments were considered in the main plots as factorial and cultivars were placed in subplots. Two planting dates were regular date (October 7) (PD1) and late planting date (November 6) (PD2). Irrigation was also carried out at two levels of normal irrigation (NI) and irrigation interruption from flowering stage onwards (II). Experimental cultivars included ES Hydromel, ES Alonso, ES Darko, ES Lauren, and Ahmadi. According to the results, late-season drought stress and delayed planting date reduced leaf relative water content (LRWC), total chlorophyll content (TCC), proline (LPC), and grain yield (GY), and increased stomatal resistance (SR), canopy temperature (CT), and leaf soluble carbohydrates (CLS) in rapeseed cultivars. The highest grain yield (4505.6 kg ha-1) was obtained in NI conditions and PD1. Significant interactions of planting date, irrigation, and cultivar on LRWC, SR, and CLS traits indicated that the ES Hydromel was the most tolerant hybrid cultivar with the highest LRWC and the lowest SR and CLS levels compared to other ones in unfavorable conditions of late-season drought stress and delayed planting. To confirm these results, cluster analysis led to the formation of two clusters, where ES Darko, Ahmadi, and ES Lauren cultivars were placed in the sensitive cluster and ES Hydromel and ES Alonso cultivars were assigned to the tolerant cluster. Therefore, ES Hydromel can be introduced as a superior cultivar to be selected as a genotype that presents acceptable resistance under drought stress and late sowing in arid and semi-arid regions.

Vertisols are suited to dry-land crop production in semi-arid environments since the residual moisture in the soil can support crop growth after the end of the rainy season. However, traditional cropping systems seldom utilize residual moisture of Vertisols for crop production. Farmers need suitable crop species to sustain and enhance their production under such soil and climatic conditions. Chickpea is the strategic crop well adapted to Vertisols and derives most of its water requirements from the residual soil moisture. Yet, different chickpea varieties found to adapt and produce different yields at different locations. The experiments were conducted for two consecutive years (2016 and 2017) on farmers training centers in two districts of Southern Ethiopia. Six released varieties; Arerti, Habru, Yelibe, Naatolii, Fetenech, Kutaye and a Local check were used for the experiment. The trials were laid in a randomized complete block design with four replicates. Data were collected on phenological traits, growth and yield attributes, and grain yield. The results showed that there was significant variation among the tested chickpea varieties in all the agronomic traits recorded. Varieties Arerti and Habru revealed superiority in grain yield, pod setting, hundred seed weight and biomass over the Local check across locations. Based on yielding performance and farmers’ preference, varieties Arerti and Habru are recommended for production in the selected districts and similar agro-ecologies in southern Ethiopia.

Sustainable crop production is required for the semi-arid areas, and it will be achieved by the wise use of several production inputs which must be tailored to the unique conditions of each district. Effective nutrient management and irrigation are just two parts of the  crop production puzzle. It seems that nano-fertilizers may have high potential for achieving sustainable crop production. A field experiment was carried out to investigate the effect of adding different fertilizers on maize (S.C 704 Hybrid) growth under various irrigation regimes in Moghan, northwest of Iran. The experiment included three irrigation levels (up to ~100, ~50, and ~25% field capacity) which were applied from the beginning of the reproductive period. During the vegetative period, all plants were fully irrigated. Fertilizer treatments included control (no-fertilizer application), N  biofertilizer, P  biofertilizer, nano-chelated  B, nano-chelated  Zn, complete nanofertilizer, and bulk NPK fertilizer. Investigation of morphophysiological traits such as leaf area, ear length, ear diameter, relative water content, and chlorophyll content revealed that application of complete micronutrients, bulk NPK, and nano-chelated Zn significantly improved these traits over the control. A similar status was recorded for grain yield and yield components. Results indicated that although irrigation up to ~25% of field capacity (FC) reduced the grain yield compared to the control, there was not observed any significant difference between normal irrigation and ~50% FC. The best plant performance was recorded for plants grown by complete nanofertilizer under optimum or ~50% FC. Deficient irrigation up to ~50% FC could be assigned as an appropriate water management strategy in semi-arid regions to minimize water losses through evaporation and achieve higher water use efficiency. In conclusion, a combination of precision deficient irrigation and application of nanofertilizers play a critical role for enhancing the efficient use of water and improving the productivity of maize production systems in Mediterranean semi-arid regions.

In this study, the effect of nitrogen doses on yield and quality characteristics of durum wheat varieties (Levante, Zenit, Yelken 2000, Dumlupınar, Eminbey, Altın, Ç-1252, and Kızıltan-91) was investigated. The research was conducted in Isparta ecological conditions in 2010-2012 seasons using different nitrogen doses of 0, 5, 10 and 15 kg/da N. The experiments were carried out for two years using randomized complete block design with three replications in factorial arrangement. All of the phosphorus (6 kg/da P2O5) and half of the nitrogen were given with sowing and the other half of the nitrogen was given during the tillering period. As a result of two years in this study, it was determined that nitrogen doses have a significant effect on all examined characteristics (number of spikes per m2, grain yield, 1000 grain weight, test weight, vitreousness and crude protein ratio). But the effect of nitrogenous fertilization varied significantly according to the varieties. In general, increasing in the amount of nitrogen above 10 kg/ha did not create a statistically significant increase in other characteristics except 1000 grain weight. As a result when grain yield and quality characteristics are taken into consideration, 10 kg/da N dose and Çeşit-1252, Altın, Kızıltan-91 and Dumlupınar varieties could be recommended in Isparta conditions.

Grain Yield And Quality

The grain yield of rice is far below from its potential yield due low organic matter and micronutrients in the soil. Application of cow dung and zinc fertilizer increases grain yield and quality. A field experiment was, therefore, conducted to evaluate the effect of zinc fertilization and well decomposed cow dung on the spikelet sterility, yield, zinc concentration in grains and plants of aromatic rice (cv. Tulsimala). In this experiment,two levels of well decomposed cowdung (CD) of 0, 10 tha-1, and fourdoses of zinc fertilization viz. 0, 2.16, 4.32, 6.48 kg ha-1 of zinc were used followingeight treatment combinations. The experiment was laid out in a factorial randomized complete block design (RCBD) with replication thrice. The data revealed that zinc fertilization remarkably increased the grain yield of Tulshimala by reducing the spikelet sterility percentages in both conditions of CD and the efficiency of zinc fertilization was superior in manuring (CD) condition to non-manuring condition. However, zinc fertilization at the rate of 4.32 kg ha-1 of zinc produced the maximum grainyields under manuring and non-manuring conditions. Zinc fertilization increased the concentration of Zn in the rice plants and grains without and with CD. The strong linear relationship between the grain yield and zinc concentration in the rice plants and grains was found with in this study. Zinc fertilization increased grain yield and quality by decreasing sterility percentage under CD. Hence, for increasing productivity towards food security in future generation, integrated use organic and inorganic fertilizers should be used.
