The effect of zinc fertilization and cow dung on sterility and quantitative traits of rice

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.

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.

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.
