für 49.41€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Rainfall being a stochastic variable, the spatial and temporal distribution as well as quantity is highly unpredictable and erratic. Consequently rainfed farming especially in the arid and semi-arid areas is a major challenge. Drought and crop failures are quite common in these areas as the soil moisture availability often does not match with the evaporation loss. In order to address these problems, standardization of technologies viz. in situ rain-water harvesting and conservation is inevitable for increasing crop productivity. A substantial part of post-monsoon (January - April) rains can be effectively harvested through land shaping and using suitable mulches. With such models arid fruit crops like ber, bael, aonla, pomegranate, custard apple, wood apple, phalsa, fig etc. may be grown profitably. Considering the above facts a research programme on efficiency of different in situ rainwater harvesting techniques for improved productivity and quality of aonla, ber, custard apple and pomegranate were carried out and the inferences drawn from the study is compiled. ····· 103613364

In the recent past, the successful SRI practices are being extrapolated to other crops in the name of System of Crop Intensification (SCI). The SCI practices also proved to increase the yield levels more than two times. In pursuit of extending the beneficial effect of SRI to SCI in greengram, the present study was programmed. Greengram is one of the important food legumes grown in India and emerged as a nutritive and remunerative pulse crop, capable of providing the quickest return in the shortest possible time besides offering nutritional security to millions of people. By virtue of its superior nutritional quality, short duration and high monetary return, greengram can be grown as intercrop and rice-fallow crop especially by small and marginal farmers. Adoption of SCI practices may enhance the productivity and reduce the gap between per capita availability and consumption and in turn possible to contribute to nutritional security of the world. ····· 103613353

It is said to be originated in Mediterranean region. It produces an enlarged fleshy tap root that is edible and possesses high nutritive value.The popularity of carrot is increasing day by day in Bangladesh especially among the urban people because of its high nutritive value and possible diversified use in making different palatable foods. Plant spacing and Sowing time is one of the important factors for the increased production of carrot. To extend the availability of carrot during the early and late period of growing season and sowing time may play a critical role. Also quality of the roots depends on the harvesting time under Bangladesh condition. There is also a significant interaction between plant spacing and sowing date. ····· 103613328

Consequently, nutrient disorders seem among the most critical factors of crop production, particularly in salt-affected soils. The essentially of P and Zn for plants has been established long ago but interaction effects on economic yields of crops are still controversial. Wheat is the most important cereal crop in the world. In a pot study on wheat grown on salt-affected soil, results indicated that mean number of tillers per pot, height of fertile tillers, straw dry weight, 1000-grain weight and P uptake in straw was recorded maximum with control closely followed by T5 (P @ 150 kg ha-1 + Zn @ 10 kg ha-1) while Zn concentration was maximum in straw and grains, P uptake by grains, Zn uptake by straw and grains with P @ 150 kg ha-1 + Zn @ 10 kg ha-1. However, when P-Zn interactions were investigated, it was observed that application of 150 kg P ha-1 & 10 kg Zn ha-1 could be the appropriate fertilizer combination for significant increase in growth and yield of wheat in salt-affected soil. Moreover, adverse effect of salinity/sodicity can be minimized by increasing the fertility status of the salt-affected soil. ····· 103613324

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In Sub-Saharan Africa, sorghum is the second most widely grown cereal crop after maize. Sorghum is largely grown in the marginal, arid and semi-arid areas where annual rainfall is very low, erratic, poorly distributed and soils are of low fertility. In these marginal areas, the grain yields of sorghum are very low due mainly due to the frequent drought stress and intense Striga weed infestations. Stay-green a secondary trait in sorghum has been used to measure drought tolerance. To overcome, the effects of drought stress and Striga damage, plant breeders have utilized molecular markers to select for the quantitative trait loci (QTL) of the stay-green trait and Striga resistance. The development and utilization of drought tolerant and Striga-resistant sorghum varieties holds the best promise of combating and reducing the effect of drought stress and Striga weed on sorghum yield in Africa. The studies reported here utilized molecular markers for the stay-green trait and for Striga resistance already available in the public domain to select for the respective QTL and to integrate the selected QTL into farmer preferred sorghum varieties of Eastern Africa. ····· 103613302

Spoilage occurs more frequent when sprouts are not refrigerated. Sprout can be easily bruised and readily infected with various micro-organisms during handling and transportation. Sprouts cannot be stored for longer time under ambient conditions. So a method to increase the shelf life of sprout would be advantageous to producers as well as to the consumers. This book is an outcome of a research done to assess the shelf life of chickpea sprouts under modified atmospheric packaging. The shelf-life was extended by designing a suitable modified atmospheric packaging system and created a favorable environment by the use of suitable polymeric film based on the design calculations. A mathematical model was also developed and validated. The technology was successful in extending the postharvest life of chickpea sprouts under modified atmosphere at 10 degree celcius.

Specifically, the main purpose of this study was to quantify the impact of changes in temperature, solar radiation and CO2 concentration that affect the level of wheat production. The impact of climate change on wheat production can be minimized through adaptability, varietal management and agronomic practices using CERES-wheat model. In Uttarakhand, wheat productivity accounted 15 % to 30 % more with the timely sown crop (20th November) than late sowing. Wheat yield has the positive correlation with CO2 concentration and negatively correlated with temperature. This book, therefore, provides a new metric of success for farmers to deciding agricultural operations and minimize the risks and extremely important to planners in the developing countries which will be the most vulnerable to the effects of global warming. ····· 103613172

Esto no implica que su actividad en cuanto a la absorción de nutrientes no pueda mantenerse más allá de dicho estado fenológico. Los objetivos del presente trabajo fueron analizar la producción, distribución y actividad radical y su grado de incidencia sobre la calidad, en etapas tardías del desarrollo del cultivo, bajo fertilización y dos sistemas de labranza en tres cultivares de trigo pan. Mientras que la materia seca aérea se incrementó paulatinamente para cada estado fenológico considerado, la materia seca radical, en términos generales, disminuyó desde antesis hacia madurez. No obstante su actividad específica no sólo se mantuvo relativamente constante sino que incluso aumentó durante la última etapa analizada, lo que sugiere que el N acumulado en el grano por el cultivo no sólo proviene del N removilizado sino también del absorbido postantesis, indicando que la actividad radical es un proceso que puede mantenerse durante estados avanzados del cultivo bajo buenas condiciones de fertilidad del suelo. ····· 103612958
