Varying Seed Rates on Yield Performance

A field experiment was conducted to review the consequences of seed rates and selection on yield and yield elements of winter wheat (Triticum aestivum. L) at Panmure Experiment Station, Shamva District throughout 2018 winter cropping season. Six levels of seed rates (60; 80; 100; 120; a hundred and forty and a hundred and sixty kilo ha-1) and 3 varieties (Dande, Kana and Ncema) were tested. The experiment was arranged out as a irregular complete block style (RCBD) and was replicated thrice. Phenological growth, yield and yield connected knowledge were collected and their multivariate analysis was analyzed exploitation Cropstat version seven.0 and wherever treatment means that were considerably completely different, they were separated exploitation the smallest amount important distinction (LSD) at five-hitter likelihood level.
The results showed that exploitation {different|totally completely different|completely different} seed rates on different varieties had important effects. solely 5 parameters that embody days to flowering (flowering), days to physiological maturity, plant height, stem lodged plants and variety of impactive tillers per web plot had important effect on completely different seed rates. However ear length and average tillers per plot had no important effects to seed rates. The interaction of seed rates on grain yield and varieties conjointly showed no important distinction (p = zero.363) on grain yield. However, Kana had the best yield of 2927.5 kilo ha-1 and this was achieved at 32g/plot (80 kilo ha-1) seed rate.
There was significance (p zero.01) interaction between selection and seed rates with relevancy flowering time. Dande was the primary to achieve flowering at day fifty nine, beneath seed rate of 40g/plot (110 kilo ha-1) and 64g/plot (160 kilo ha-1). there have been important (p < zero.01) interactive effects of selection and seed rate with relevancy physiological maturity. Ncema selection induced earliest maturity, reaching physiological maturity at day 116 once emergence and this was achieved beneath seed rate of 24g/ plot (60 kilo ha-1) seed rate. However, any studies ought to be done beneath completely different soils exploitation higher seed rates over a hundred and sixty kilo ha-1 and reducing the entomb row spacing from zero.25m to 0.2m so as to use the advice of this study.
Agriculture is that the mainstay of the Zimbabwean economy providing livelihoods to about seventieth of the population, conducive between V-day and two hundredth of Gross Domestic Product (GDP) and providing four-hundredth of export earnings and activity sixty three of agro-industrial raw materials (Kapuya, Jongwe and Saruchera, 2010). This makes the agricultural sector strategic and really vital sector in coming up with ways and policies to scale back financial condition, cut back food insecurity and boost rural incomes. Republic of Zimbabwe Central applied mathematics workplace (ZIMSTAT) (2012), revealed a report on however wheat (Triticum aestivum. L) is that the second most significant strategic food security crop in Republic of Zimbabwe once maize. Wheat has become a staple crop given its high demand for bread and alternative confectioneries.
Wheat farming could be a major cropping activity and also the goods is extremely valued significantly its product, bread. Bread has become a key staple food in Republic of Zimbabwe so creating wheat the second most significant crop once maize, Kapuya et al. (2010). Wheat contributes regarding four p.c to the value of {zimbabwe|Zimbabwe|Republic of Republic of Zimbabwe|Rhodesia|Southern Rhodesia|African country|African nation} (Reserve Bank of Zimbabwe (RBZ), 2009). The immediate wheat merchandise area unit flour and bran. Flour is that the main ingredient for creating bread and alternative confectionaries consumed daily by largely urban Zimbabweans whereas wheat bran is especially employed in the stock feeds producing sector.
