The nature of soil type is an important factor in the bioaccumulation of substances in plants. Application of nitrogen fertilizer is a common practice in vegetable farming. This study was therefore co...
Effect of foliar application of mepiquat chloride (1,1- Dimethyl-piperidinium chloride 5% SL (W/V), a plant growth regulator, was assessed on seed cotton yield (cv. CIM-473) at Agronomic Research Stat...
A study was conducted during kharif season of three successive years from 2001 to 2003 at Rice Research Institute, Kala Shah Kaku, Lahore, Pakistan. Nine nitrogen levels (0, 50, 75, 100, 125, 150,...
Two experiments were carried out to analyze the expression of some agronomic characteristics by semidwarfing gene sd-1, which has played an important role in improvement of rice productivity per area....
Under the two types of nitrogen dressing which prevail in Miyagi prefecture, rice cv. Sasanishiki was cultivated in the paddy field, and the tillering pattern was analyzed. One type of nitrogen dress...
Using high tillering semidwarf indica, IR36, and panicle type and low-til1ering japonica, Koganenishiki (KN), varietal differences of tillering response to shading and nitrogen (N) levels were studied...
Supernodulating soybeans, having several times more nodules than normal genotypes, are expected to produce higher dry matter and grain yields through a higher nitrogen fixation potential. However, the...
Effects of Shading and Fertilized Nitrogen Levels on the Growth, Yield Components and Physicochemical Properties of Rice.
Scarcity of water and N fertilizer are major constraints to rice production, particularly in developing countries where rainfed upland condition dominates. Improvement of genetic adaptability to inade...
The purpose of this study was to discuss the practical usefulness of the discrimination of indica and japonica cultivar groups based on the morphology of silica bodies from motor cells in rice (Oryza ...
This study was carried out to determine the effect of four nitrogen levels on forage yield and some attributes three corn cultivars under irrigated conditions in Mustafakemalpasa, Bursa, Turkey in 200...
The effects of 2 irrigation intervals (If1: 7 days and If2: 14 days), 4 nitrogen doses (Ng, N0, N1, N2 and N3) and 2 crop coefficients (Kpc1: 0.60 and Kpc2: 0.90) on pistachio nut fertigation were stu...
An field experiment was conducted during kharif, 2005 at Tamil Nadu Agricultural University Farm, Coimbatore, India to study the effect of different sowing dates (June 8th, June 23rd, July 8th and Ju...
Cooking and nutrition qualities of grain are two of the most important aspects of rice quality. To understand the difference in cooking and nutrition qualities among the grains at different positions ...
The experiment was carried out to study effect of two corn varieties intercropping combinations (75%SC704:25%SC604, 50%SC704:50%SC604, 25%SC704:75%SC604) on land use efficiency at various nitrogen lev...
