Varietal trial of cabbage

Chetram, R.S. [1970]

The objective of this trial was to determine the yield potential and adaptability of 8 varieties of cabbage under Guyanese conditions. The experiment was conducted on onverwagt clay and each variety was replicated twice. The variety KK Cross had the highest yield of 32,648 lbs/acre and showed a high degree of resistance to black rot disease. It also had the highest heading percentage (95 %)

Soyabean spacing trial

Chetram, R.S. [1969]

The trial was conducted on sandy clay soils and the variety chosen was 240664. 3 inter-row spacings 6, 12 and 18 inches and 3 row spacings 4, 6 and 8 inches were compared. Results were not significant. However, when the spacing 6 inches x 4 inches was compared with the standard spacing, 18 inches x 6 inches, the former outyielded the latter by 897 lbs/acre

Varietal trial of tomatoes

Chetram, R.S. [1970]

A trial was conducted to determine the yield potential and adaptability of 11 varieties of tomatoes on onverwagt clay under Guyanese conditions. The variety Ogier gave the highest yield of 20,368 lbs/acre, but produced the smallest fruits. The yield of most of the varieties was low due to nitrogen and phosphorus deficiency and nematode attacks

An experiment to determine the yield potential of 11 varieties of sweet potatoes, including the local variety, White Lady, was carried out on onverwagt clay with a sandy substratum. The highest yield of 43,802 lbs/acre was obtained with the variety T67; C9/9 and 26/10 yielded over 40,000 lbs/acre and the local variety yielded 34,727 lbs. The lowest yield of 24,926 lbs/acre was obtained with th ...

The trial was conducted with the long-range objective of developing cassava as a supplemental cattle feed. Planting stock of 10 promising varieties of sweet cassava obtained from CIAT and 2 varieties obtained from farmers near Ebini, were included in the non-replicated variety test carried out on Kasarama loamy sand. Results indicated that acceptable yields can be produced on the intermediate ...

Corn varietal trial

Chetram, R.S. [1969]

The varieties used were Pioneer X 304, X 306, X 332, X 348, Oregon and Charity. Pioneer X 304 outyielded the others. The data indicated that the increase in yield was significant at 1 % level. With reduced spacing and increased fertilizers a yield of 6,000 lbs/acre can be obtained with Pioneer X 304
