Crop models are powerful tools to test hypotheses, synthesize and convey knowledge, describe and understand complex systems and compare different scenarios. Models may be used for prediction and planning of production, in decision support systems and control of the greenhouse climate, water supply and nutrient supply. The mechanistic simulation of tomato crop growth and development is described...

The effectiveness of Architect, SE growth regulator (mepiquat chloride, 150 g/l + pyraclostrobin, 100 prohexadione-calcium, 25 g/l) in winter rapeseed var. Vitovt and Mazari Mercedes hybrids is shown. application the preparation phase 4–5 leaves at rate 1,5 l/ha reduces height growing point by 47,7–55,2 %, increases diameter root crown on average 13,5–22,8 crop overwinter survival 3,7–12,3 % oi...

Nutrient recycling in a space-based Bioregenerative Life Support System (BLSS) will require an understanding of nutrient dosage effects on crop production, plant tissue partitioning, and geochemical fates within crop systems. Sodium (Na+), fluoride (F−), and iodide (I−) are found in human waste streams. These elements were examined using crops in hydroponic systems. Lettuce, radish, spinach, an...

The host suitability of 64 commercial corn hybrids for a Meloidogyne arenaria race 2 population and a M. incognita race 4 population was determined in greenhouse experiments. 'Northrup King 508' and 'Pioneer Brand 3147' maintained M. arenaria below and at the initial population level, respectively, indicating that these hybrids are relatively poor hosts for this species. RF values (final egg nu...

However, the inhibitory materials may be autoinhibitory or heteroinhibitory (Kumari and Kohli, 1987), some White top [Cardaria draba (L.) Desv.] and Syrian sage (Salvia can be highly selective (Stachon and Zimdahl, 1980; syriaca L.) are noxious common weeds of field crops and orchards Sahid and Sugau, 1993), and their effect is concentration in Jordan. This study was conducted to investigate an...

Isabgol is a major export oriented medicinal crop of India. The genetic variability available in this crop is limited owing to the narrow gene pool existing in our country. The physiological and growth characteristics of selected 7 species of Plantago were studied at DMAPR, Boriavi to investigate the relationship with the seed yield. Among the species studied, the lowest SLA (specific leaf area...

In a pot culture experiment, the root length density, potassium concentration in crop, and total K uptake by wheat (Triticum aestivum var. HD 2285) at different growth stages (CRIS-Crown Root Initiation Stage, MTS-Maximum Tillering Stage, FLS-Flag Leaf Stage and DFS-Dough Formation Stage) were determined. Wheat crop was grown in 72 pots containing 4.5 kg of three types of soils, namely Alfisol,...

The experiment was conducted at crop research farm in the department of agronomy during summer season 2022 on cowpea crop. treatments consisted 3 levels Boron (0.75,1,1.25 kg/ha) and Plant Growth Regulators (GA3 30 ppm, NAA 35 ABA 40 ppm ) as a foliar spray. laid out Randomized block design with 9 replicated “thrice”.0.75 kg/ha soil application combination gibberellic acid spray recorded maximu...

Two experiments, each consisting of 2 trials, were conducted to investigate the effect of feeding benzoic acid (BA) and turmeric meal (TM) individually or in combination (Exp. 1) or garlic meal (GM) and TM individually or in combination (Exp. 2) on growth performance, digesta pH, gut morphology, and nutrient utilization in broiler chickens. Diets consisted of a nutrient-adequate control diet an...
