The recent estimates that world s P reserves end by 2050 compelled scientists to explore the alternate means of crop phosphorus nutrition. The use of ACC-deaminase rhizobacteria for improved crop yield is now well established. However, no study reports the role of ACC-deaminase rhizobacteria in improving wheat yield based up on their phosphate solubilizing activity. The present book focuses up on the possibility of utilizing phosphate solubilizing ACC-deaminase rhizobacteria for sustainable wheat production under low-phosphorus-input agriculture. ····· 1036192141

As walnut required chilling temperature for its bearing. But its cultivation is impossible in low altitude area of the country. It can be grown in high as well as low altitude areas of our country. It will fetch higher prices in the market due to its unique taste and nutritious values. The trees may live and bear edible nuts for more than three hundred years. The major constraint in its spreading is stunted and restricted growth during seedling stage in the nurseries. An attempted has been made to furnish baseline information on the different concentration of nitrogen and zinc application to the Pecan nut seedling for bumper growth.

The experimental soil was silty clay, pH 6.0. The treatments were 4 levels of vermicomposts viz. V0 (0 t ha-1), V1 (1 t ha-1), V2 (2 t ha-1),V3 (3 t ha-1), and 4 levels of fertilizers viz. F0 = (0-0-0 kg ha-1), F1 = low (40-30-20 kg ha-1), F2 = medium (80-60-40 kg ha-1), F3 = high (120-80-60 kg ha-1) of N-P2O5-K2O with 16 treatments combinations and 3 replications. The results showed that with increasing the doses of vermicomposts and fertilizers increased grain and straw yield significantly up to a level. The maximum significant grain and straw yields were obtained with the treatment combinations V3F2 or V2F3. The highest doses of vermicompost and chemical fertilizers increased N,P,K and S concentrations in wheat plant significant at different stages of plant growth and also enhanced N, P, K and S uptake significantly at the ripening stage.

Breeding disease resistant varieties is the socio-economical and viable alternative to reduce the cost of cultivation. Since Banded leaf and sheath blight (Rhizoctonia solani f.sp sasakii) has become a disease of major concern in maize only recently, little work on genetic analysis and breeding for resistance to this disease has been undertaken. Moreover only a few resistance sources have been identified. So the emphasis was to screen additional inbred lines for identifying potential new sources. Also genetic analysis of resistance needs to be undertaken to understand the mechanism as well as to devise appropriate strategy for incorporation of resistance as well as to improve yield. By involving diverse maize inbred lines with different disease reactions, experimental hybrids with higher productivity and resistant to BLSB can be generated. This book provides an insight to the genetics of resistance to banded leaf and sheath blight along with yield.

In fact, we need the farming procedures on which the land characteristics meet the crop requirements and lead to the sustainable agricultural production. In this case, land suitability evaluation can provide data on the basis of which we are able to make decision about alternative cultivation in agricultural lands. Moreover new technologies such as remote sensing and geographical information systems have the ability to produce basic maps and interrelate spatially multiple types of information. This book, therefore, provides a method of generating land cover map as a basic map to investigate and show the results of land suitability evaluation. Also a practical instance of land suitability evaluation for major crops cultivated in Ardebil, Iran is investigated.
