Substantial increases in grain yield of cereal crops are required to feed a growing human population. Here we show that a natural variant of SEMIDWARF AND HIGH-TILLERING (SDT) increases harvest index and grain productivity in rice. Gain-of-function sdt mutation has a shortened polyadenylation tail on the OsmiR156h microRNA precursor, which cause the up-regulation of OsmiR156h. The plants carryi...

OsWUS has recently been shown to be a transcription factor gene critical for tiller development and fertility in rice. The OsWUS protein consists of three conserved structural domains, but their biological functions are still unclear. We discovered a new rice mutant resulting from tissue culture, which hardly produced tillers and exhibited complete female sterility. The male and female floral o...

The teosinte branched1(tb1) gene is a major QTL controlling branching differences between maize and its wild progenitor, teosinte. The insertion of a transposable element (Hopscotch) upstream of tb1 is known to enhance the gene's expression, causing reduced tillering in maize. Observations of the maize tb1 allele in teosinte and estimates of an insertion age of the Hopscotch that predates domes...

A field experiment was conducted during kharif 2015-17 to study the efficacy of growth retardants on physiology and yield pearl millet at Durgapura (Jaipur). Growth retardants, viz. cycocel mepiquat chloride were sprayed @ 250, 500 750 ppm tillering (40 DAS) flowering (60 stages. The laid out in randomized block design with 4 replications. Results showed that plant height decreased, whereas chl...

A field experiment was carried out to identify the best suitable rice variety for aerobic cultivation in Cauvery delta region. Ten ruling varieties were sown two consecutive Kharif seasons, with regular nutrient and weed management practices under condition. Growth parameters viz.,plant height, leaf area index, root length dry weight studied. Similarly yield viz., panicles m-2, Dry matter produ...

Spatial variation in sugarcane production is examined relation to weather variables understand the role of climatic conditions controlling yield states Maharashtra and Uttar Pradesh (and Uttaranchal). Since a set optimum that are conducive for maximum rate growth this crop already documented, it also important assess at each phases from values making microclimatic manipulation by using mulch ir...

In modern socio-economic conditions, the production of high-quality grain remains main task agricultural production. The way to solve it is increase productivity by introducing new varieties and crops with high potential improving cultivation technology minimal costs. Agrarians North-East Non-Chernozem Zone Russia, having in their land, use poorly fertile sod-podzolic soils varying degrees cult...

This work aimed to study the competitive ability between Paspalum virgatum L. and Panicum maximum cv. Mombaça in different soil fertilities. Three independent experiments were set up a completely randomized design, with four replications. Each experiment corresponded levels of fertility (low, medium high) arranged substitutive series proportions 100:0, 75:25, 50:50, 25:75 0:100% The height, num...

In the present study, the research results concluded that yield attributes of scented rice under aerobic culture responded up to 150 kg/ha nitrogen with four equal splits of nitrogen at 1⁄4 basal + 1⁄4 at active tillering + 1⁄4 at panicle initiation and 1⁄4 at heading. Grain and straw yields obtained higher values with highest level of nitrogen i.e. 175 kg/ha comparable with 150 kg/ha. Grain qu...
