In this issue: Solar Protein
by Keelnatham T. Shanmugam , Raymond C. Valentine
Research is under way to investigate the possibility of creating new hybrid plants the self-sufficient for nitrogen, regulating and enhancing nitrogen fixation by legumes, and introducing a nitrogen-fixing symbiosis to grasses and cerals.
Modoc a new durum wheat for northern California
by Y. Paul Puri , Calvin O. Qualset , Kenneth G. Baghott , Herbert E. Vogt , William F. Lehman , E. Wayne Hempleman , William C. Shuey , John D. Prato
Modoc, a high-yielding, short-statured durum variety developed for the Tulelake area, produces grain of good for milling.
Dairy manure can be used safely
by Jewell L. Meyer , Roy S. Rauschkolb , Earl H. Olson
Research and experience have shown that proper management is the key to using dairy manure to fertilize crops without creating environmental problems.
Black scale now a major olive pest
by G. Steven Sibbett , John E. Dibble , John D. Babcock
Not available – first paragraph follows: Black scale, Saissetia oleae (Oliver), has, until recently, been a minor pest of olive in California, and the specific chemical controls established for black scale have seldom been used. Chemical control of another scale, Parlatoria, a more serious pest of olive, resulted in some inadvertent control of black scale.
Rotation ineffective as verticillium control
by Oen C. Huisman , Lee J. Ashworth
Not available – first paragraph follows: Verticillium wilt, caused by Verticillium albo-atrum, is a major pathogen of cotton and several other California crops. The pathogen is a soilborne fungus, attacking its host through the root system. It survives long host-free periods in naturally infested soil as micro-sclerotia, which are formed in infested host tissue. Incorporation of this host tissue into the soil and its subsequent decomposition are responsible for the inoculum levels of this fungus in the soil.
Drip application of nitrogen is efficient
by Robert J. Miller , Dennis E. Rolston , Roy S. Rauschkolb , David W. Wolfe
Not available – first paragraph follows: Fertilizer uptake by irrigated plants is influenced considerably by fertilizer placement and timing and by water application methods. Because some fertilizer elements move with water in the soil, these plant nutrients must remain or arrive within the sphere of the plant roots after fertilizer and water are applied. The goal is to develop cultural practices by which crop nutrient needs are satisfied by maximum uptake from a minimum quantity of applied fertilizer.

Maintaining quality of fruits and vegetables
Not available – first paragraph follows: A major portion of the estimated $200 million annual losses of fruit and vegetable during shipment and marketing can be attributed to disease caused by less than a dozen fungi and bacteria. Significent progress has been made in controlling these diseases.
